[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail with reference to the accompanying drawings.

Example 1

[0039] Figures 1, 2, 3, 4, and 5 show Embodiment 1 of the present invention. In this embodiment, a portable backpack device is provided, which includes a back frame 1 and a strap system 12. The frame 1 includes two uprights 1T and bottom supports 1-2. The two uprights 1-1 are located on both sides of the back of the human body. The uprights 1-1 are curved according to the biological curve of the back of the human body. The bottom supports 1-2 are set on the back of the human body. At the bottom end, a load-fixing self-locking device 2 is arranged between the columns 1-1, the load is placed on the back frame, and is limited and fixed by the load-fixing and self-locking device 2, and the bottom bracket 1-2 supports the load below.

[0040] The strap system is connected and fixed with the back frame 1, and the back frame 1 is carried on the back of the human body through the strap system.

[0041] Column 1-1 imitates the design of the biological curve of the human back, especially combining the average height of Chinese soldiers and the average carrying size of portable equipment products, in line with the human bone curve in the Chinese military ergonomics, and the back streamline design can closely fit the human body , It solves the problem of uncomfortable shaking and uncomfortable shaking after being carried by the existing back frame products that do not fit the human back.

[0042] The arc curve of the column 1-1 is also suitable for gripping, which enhances the user's comfort when taking the portable back frame 1.

[0043] As shown in FIG. 3, a number of lateral reinforcement bars 1-6 are arranged from top to bottom between the two uprights 1-1, and brackets 1-3 are also arranged between the uprights 1-1, and the backs of the brackets 1-3 are also provided. Bulging toward the back of the human body, a number of vertical reinforcing bars 1-4 are arranged on the bracket 1-3, and the load-fixing self-locking device 2 is arranged on the vertical reinforcing bars 1-4.

[0044] The bracket 1-3 bulges back toward the back of the human body, so that the supporting surface of the bracket 1-3 is at an appropriate distance from the human body, leaving a working space for the load-fixing self-locking device 2.

[0045] In this embodiment, the bracket 1-3 includes two symmetrically arranged U-shaped frames, which are respectively fixed on a column 1-1; the horizontal reinforcement strips 1-6 and the vertical reinforcement strips 1-4 are both present Plate-shaped.

[0046] The horizontal reinforcement bar 1-6 includes three, the vertical reinforcement bar 1-4 includes three, and the vertical reinforcement bar 1-4 located in the middle connects the U-shaped frames on both sides, so that the two U-shaped structures form a whole .

[0047] As shown in FIGS. 1 and 2, the load-fixing self-locking device 2 includes two rows of hanging slots 1-5 arranged on the front of the vertical reinforcement bar 1-4, and two rows of hanging slots 1-5 arranged on the back of the vertical reinforcement bar 1-4. Two fixing strips 6, the fixing strip 6 is provided with cylindrical pins 14 corresponding to the hanging grooves 1-5, and the vertical reinforcing strips 1-4 are provided with long holes corresponding to the cylindrical pins 14, and the cylindrical pins 14 extend into the hanging holes through the long holes. In slots 1-5; a U-shaped buckle 5 is provided on the load, an R-shaped limit groove is provided on the outer hook plate of the buckle 5, and a wedge-shaped lock tongue is provided on one side of the limit groove, and the hook plate is inserted into the In the hanging grooves 1-5, the cylindrical pin 14 is connected and locked with the limit groove to limit and fix the load.

[0048] The outer hook plate of the buckle 5 is designed with an R-shaped limit groove, which facilitates the cylindrical pin 14 to enter the limit groove and be locked.

[0049] A number of connecting holes are provided on the inner hook plate of the buckle 5, which can be fitted with screws and fixed on the load.

It can ensure that the back frame 1 is well-stressed, pressure-resistant and wear-resistant, reduces the load of the carrying personnel, and solves the shortcomings of the existing portable back frame of heavy weight, large volume and poor user experience.

[0051] For structural strength requirements, the fixing strip 6 and the buckle 5 are made of stainless steel. The cylindrical pin 14 can be vertically welded and fixed on the fixing bar 6.

[0052] As shown in FIGS. 2 and 4, a locking strip 4 is provided on the back of the vertical reinforcement strip 1-4, the locking strip 4 is U-shaped, and the locking strip 4 limits the fixing strip 6 to the vertical reinforcement strip. On 1-4, the fixed strip 6 can move horizontally back and forth in the locking strip 4.

[0053] The fixing strip 6-end is provided with a clamping hole 15, the column 1-1 is provided with a load ring locking device 7, and the load ring locking device 7 is provided with a hook 7- corresponding to the clamping hole 15 on the fixing strip 6. 1. Move the fixing strip 6 to set the clamping hole 15 on the hook 7-1, the cylindrical pin 14 and the limiting groove are in an unlocked state, and the buckle 5 is taken out from the hanging groove 1-5 to remove the load.

[0054] The card hole 15 needs to be designed as a long hole, so that it is convenient to put the card hole 15 on the hook 7-1.

[0055] As shown in FIG. 4, the fixing strip 6 is provided with three U-shaped bends, and the cylindrical pin 14 is provided on the protrusion of the U-shaped bend. The design is to facilitate the cylindrical pin 14 to extend into the hanging groove 1-5 in.

[0056] The U-shaped bend in the upper and middle part of the fixing strip 6 is provided with an elastic recovery device 8. When the fixing strip 6 moves toward the load ring locking device 7-side, the elastic recovery device 8 is compressed and stored by the support 1-3, cylindrical When the pin 14 and the limit groove on the buckle 5 are in the unlocked state, under the action of the elastic restoring force of the elastic restoring device 8, the fixing bar 6 moves away from the load ring locking device 7 until the cylindrical pin 14 and the limit position The groove is in a locked state, and the buckle 5 cannot be taken out from the hanging groove 1-5 at this time.

[0057] In this embodiment, the elastic recovery device 8 includes a spring and a positioning column, the positioning column is arranged in a horizontal state, the bottom end of the positioning column is fixed at the U-shaped bend, the spring is sleeved on the positioning column, and the brackets 1-3 The upper corresponding positioning post is provided with a socket. When the fixing bar 6 moves toward the load ring locking device 7 side, the positioning post is inserted into the socket on the bracket 1-3, and the spring is compressed and stored by the bracket 1-3.

[0058] When the cylindrical pin 14 is in a locked state with the limiting groove, the positioning column of the elastic recovery device 8 is still inserted into the socket on the bracket 1-3.

[0059] As shown in FIG. 4, the upper and lower ends of the locking strip 4 are respectively provided with bolts, and the vertical reinforcement strips 1-4 are correspondingly provided with threaded holes, and the locking strip 4 is installed and fixed in the vertical through the bolts and threaded holes. To the reinforcement bar 1-4.

[0060] The bottom support 1-2 is U-shaped, and the connection between the bottom support 1-2 and the column 1-1 is provided with a triangular reinforcing rib plate, and the end of the bottom support 1-2 facing away from the back of the human body is bent downward to form a footrest. The feet are used to maintain balance when the person places the portable backpack on the ground.

[0061] A number of cross bars are provided in the bottom support 1-2, which can support the load.
