In addition, corresponding to the receiving groove 782 of the sliding member 70, the connecting plate 82 of the rotating member 80 is provided with a notch 826, and the notch 826 is close to the sliding handle 842 and away from the rotating handle 840. Corresponding to the convex point 789 on the fixed portion 78 of the sliding member 70, a recess 828 is formed on the rotating member 80.

When assembling, when the rotating member 80 is connected to the fixing portion 78 of the vertical plate 74 of the sliding member 70, the pivot hole 820 of the connecting plate 82 of the rotating member 80 is aligned with the riveting hole 784 of the fixing portion 78, and the fixing The protruding post 780 on the part 78 is inserted into the arc-shaped groove 824 of the rotating member 80, and then a rivet 90 is inserted through the pivot hole 820 of the connecting plate 82 and the riveting hole 784 of the fixing part 78, and is riveted and fixed to the riveting hole 784. In this way, the rotating member 80 is connected to the fixed portion 78 of the sliding member 70, and the rivet 90 can be rotated as the central axis, and the convex post 780 penetrated in the arc-shaped groove 824 limits the arc that the rotating member 80 can rotate. .

As shown in FIG. 7, when the convex post 780 is located at the top of the arc-shaped groove 824, the convex point 789 on the fixed portion 78 of the sliding member 70 just enters the recess 828 of the rotating member 80, so that the rotating member 80 and the sliding member 70 The buckle positioning is formed to avoid relative rotation between the two. At this time, the operating portion 84 of the rotating member 80 is approximately horizontal, and the connecting plate 82 of the rotating member 80 overlaps the fixed portion 78 of the sliding member 70, and the operating portion 84 is The sliding handle 842 is substantially upright. When an external force acts on the rotating handle 840 to rotate the rotating member 80 relative to the sliding member 70, the convexity of the sliding member 70 Point 789 is separated from the recess 828 of the rotating member 80. The rotating member 80 rotates within the range limited by the arc-shaped groove 824. When the rotating member 80 rotates until the convex post 780 is located at the bottom end of the arc-shaped groove 824, the rotating member 80 becomes inclined. In the state, the rotating handle 840 of the rotating member 80 is higher than the sliding member 70, and the slot 826 of the rotating member 80 is inclined downward, as shown in FIG. 5.

When connecting the sliding member 70 to the bracket 60, first place the sliding member 70 on the bottom side of the corresponding short side of the bracket 60, so that the connecting portion 76 of the vertical plate 74 of the sliding member 70 is located at the connection of the bracket 60. The inner side of the member 64 and the two are substantially overlapped, and the fixing portion 78 of the sliding member 70 and the connecting member 64 are generally located on the same plane. At this time, the connecting pin 66 on the tray 62 of the bracket 60 corresponds to the opening 792 of the slide groove 79 on the plate 72 on the sliding member 70, and the connecting pin 66 on the connecting member 64 of the bracket 60 corresponds to the opening 792 of the sliding member. The opening 792 of the sliding groove 79 on the connecting portion 76 of the vertical plate 74 of 70 corresponds to the opening 792, and then the end 662 of the connecting pin 66 enters the opening 792 of the corresponding sliding groove 79, and the sliding member 70 is pushed to make the sliding member 70 face each other The bracket 60 slides, more specifically, the sliding member 70 located on the left side of the bracket 60 slides backward relative to the bracket 10, and the sliding member 70 located on the right side of the bracket 60 slides forward relative to the bracket 10 until the rod of the connecting pin 66 The body 660 slides along the slot 790 of the sliding groove 79 to the closed end of the slot 790. At this time, the protrusion 644 on the connecting piece 64 of the bracket 60 is facing the second connecting portion 76 of the vertical plate 74 of the sliding piece 70. The position of the groove 762 enters the second groove 762 of the connecting portion 76, and the two form a snap fit, which restricts the relative sliding between the sliding member 70 and the bracket 60, and temporarily positions the sliding member 70 to the bracket 60superior, now the rod 660 of the connecting pin 66 is located in the chute The closed end of the slot 790 of 79, the end 662 of the connecting pin 66 abuts on the outer periphery of the closed end of the slot 790 of the slider 70, because the diameter of the end 662 of the connecting pin 66 is larger than the narrow end of the sliding groove 79 The width of the groove 790 is such that the connecting pin 66 will not fall off from the sliding groove 79 of the slider 70.

It can be seen from the above that the sliding member 70 and the bracket 60 can be conveniently connected into one body by their own snap-fitting structure. Similarly, the sliding member 70 and the rotating member 80 can also be connected into one body by their own structural fit, so that the buckle of the present invention The combined structure 50 can be easily assembled as a whole without additional assembly components. Understandably, when assembling the fastening structure 50, the sliding member 70 can be connected to the bracket 60 first, and then the rotating member 80 can be riveted to the sliding member 70 by the rivet 90, or the rivet 90 can be used to The rotating part 80 is riveted to the sliding part 70, and then the sliding part 70 with the rotating part 80 is connected to the bracket 60 together.

After the circuit board 30 is fixed to the tray 62 of the fastening structure 50, the circuit board 30 can be conveniently fixed to the substrate 10 of the server. First, as shown in FIGS. 4-6, the rotating member 80 of the fastening structure 50 is rotated to an inclined state, and the slot 826 of the rotating member 80 is inclined downward, and then the fastening structure 50 can be placed on the substrate 10 At this time, the fixing post 14 and the positioning post 16 of the substrate 10 respectively pass through the corresponding assembly hole 620 on the tray 62 and the corresponding perforation 32 on the circuit board 30. Since the assembly hole 620 and the perforation 32 are both smaller than the body 140 of the fixing post 14, Therefore, the buckle structure 50 is temporarily positioned on the supporting surface 146 of the fixed column 14 of the base plate 10. At this time, since the rotating member 80 is inclined, the pin 18 of the base plate 10 enters the receiving groove 782 of the slider 70 and cuts the rotating member 80. Slot 826. At this time, the substrate 10 rests on The two fixing posts 14 of the connecting member 64 near the bracket 60 are respectively located outside the two sliding parts 70 and opposite to the notches 720 of the two sliding parts 70, and the other two fixing posts 14 are respectively penetrated into the grooves of the corresponding sliding parts 70 722 in the round hole 724.

Then, as shown in FIGS. 7-8, the rotating handle 840 of the rotating member 80 is rotated to make the rotating member 80 in a horizontal state. At this time, the convex point 789 on the fixed portion 78 of the sliding member 70 just enters into the rotating member 80. In the recess 828, the rotating member 80 and the sliding member 70 form a buckle positioning to connect the rotating member 80 and the sliding member 70 as a whole. At this time, the two fixing posts 14 close to the connecting piece 64 are still located outside the sliding piece 70 and opposite to the notch 720 of the sliding piece 70, and the other two fixing posts 14 still pass through the round holes 724 of the slot 722.

Finally, as shown in Figures 9-10, push the sliding handle 842 of the rotating member 80, so that the rotating member 80 drives the sliding member 70 to slide relative to the bracket 60 together, so that the connecting pin 66 slides along the sliding groove 79 toward the opening 792 until the corresponding missing groove The neck 144 of the fixing column 14 of 720 completely enters the notch 720 of the sliding member 70. At this time, the necks 144 of the other two fixing columns 14 penetrated in the circular holes 724 of the slot 722 respectively enter the corresponding slot 722. In the limiting groove 726, since the head 142 of the fixed column 14 is larger than the width of the limiting groove 726 and the notch 720 of the sliding member 70, both ends of the sliding member 70 are clamped on the head 142 and the fixed column 14 The main body 140 cannot move in the vertical direction. At this time, due to the movement of the sliding member 70 relative to the bracket 60, the protrusion 644 of the connecting member 64 of the bracket 60 separates from the second groove 762 of the sliding member 70 and slides and finally enters the first groove 760, thereby protruding The ridge 644 forms a snap fit with the first groove 760 to limit the further movement of the sliding member 70 in the lateral direction. The distance between the groove 760 and the second groove 762 is less than the length of the slot 790 of the sliding groove 79. At this time, the end 662 of the connecting pin 66 is located approximately in the middle of the slot 790 of the sliding groove 79, thereby avoiding sliding The piece 70 falls off from the bracket 60. So far, the fastening structure 50 stably fixes the circuit board 30 on the substrate 10 of the server.

When the circuit board 30 needs to be disassembled from the substrate 10, it is only necessary to push the sliding member 70 in the reverse direction to disengage the fixed column 14 from the notch 720 of the sliding member 70, and then rotate the rotating member 80 so that the cut groove 826 of the rotating member 80 is inclined State, so that the buckle between the pin 18 and the rotating member 80 is released. At this time, only the buckling structure 50 and the circuit board 30 fixed on the buckling structure 50 can be moved upwards to remove the circuit board 30 from the substrate 10. Therefore, the fastening structure 50 of the present invention does not need to resort to screws and screwdrivers whether it is installed or disassembled, which is convenient and quick.
