Luggage carrier

The present invention relates to a kind of luggage carrier, and more specifically to a kind of luggage carrier in which a telescopic pipe is provided between a handle and a vehicle body.

In a conventional carrier, it consists of a steering wheel, a car body, a loading platform and wheels, the loading platform is attached to the vehicle body, and the casters are installed under the vehicle body.

<p> Although the structure of such a carrier is simple, it is inconvenient to carry due to its large volume. There is also a folding carrier, which houses the steering wheel, loading platform and casters all in the car body, and although the volume of the carrier has been greatly reduced, the structure is complicated and it is very inconvenient to operate. At the same time, due to the fixed length of the steering wheel and the car body, the steering wheel cannot be adjusted to the user's proper height, which requires extra force to pull the carrier and makes the user's hands tired easily. ..</p><p> The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a foldable luggage carrier having a telescopic device between a handle and a vehicle body.</p>

<p> In order to solve the above problems, the luggage carrier of the present invention is a kind of luggage carrier, which includes a loading platform, casters, a vehicle body, and a handle, and is connected to the vehicle body with one screw at each end of the loading platform. Two wheels are attached to the casters below the car body, and the steering wheel and the car body are connected by a multi-stage telescopic pipe.</p><p> A switchgear is installed on the multi-stage pipe. The switchgear consists of a switchgear and a switchgear, which is connected to the lock bar inside the multi-stage pipe.</p><p> The number of stages of the multi-stage pipe is changed from 2 to 4, the pipes of each stage are connected by a pipe plug, the inner pipe is provided with a hook, and there is a part inside the pipe plug of the inner pipe, which is fixed to the lock bar through the hook. Is connected. A spring and a ball are provided in the pipe plug of each pipe, and the spring is placed between the annular convex base formed on the part and the upper part of the pipe plug. The ball is placed in a hole in the wall of the pipe plug and on the ring-shaped convex base of the part. The cross section of the annular convex base described above is trapezoidal. The wall of the outer pipe does not have a hole corresponding to the pipe plug wall hole position, and the diameter of the hole is smaller than the ball.</p><p> A spiral gear is provided on each caster, a spring is fitted in the spiral gear, and a swivel pipe mounted on the vehicle body is interlocked with the spiral gear.</p>

<p> In the case of the component mounting structure according to claim 1 of the present invention, a multi-stage telescopic pipe is provided between the handle and the vehicle body to significantly reduce the volume of the carrier, and at the same time, the handle can be raised to the most appropriate height by the user. Since it can be adjusted, the user does not feel so tired when pulling the luggage. In addition, the spiral gears on the casters are linked to the swivel pipe of the car body, so the spiral gears can be driven to fold the casters when storing the loading platform. This makes the operation even more convenient.</p>

The utility model will be further described below with reference to the attached figure.

As shown in the figure, this utility model cites a three-stage telescopic pipe device as an example.

As shown in Fig. 1 and Fig. 2, this utility model luggage carrier includes the loading platform 1, casters 2, vehicle body 3, and handle 4, and is connected to the vehicle body 3 with one screw 5 at each end of the loading platform 1, and two wheels 2 respectively. Attach it to the caster 21 below the car body 3. Handle 4 and vehicle body 3 are connected by a three-stage multi-stage telescopic pipe 6.

A switchgear 7 is provided on the three-stage pipe 6. The switchgear 7 is attached to the upper end of the three-stage pipe 6, and the switchgear 7 is composed of an opening / closing base 71 and an opening / closing button 72, and the opening / closing button 72 is connected to a lock bar 8 inside the three-stage pipe 6. As shown in FIGS. 5 and 6, the pipes of each stage are connected by a pipe plug 10, a hook 9 is provided in the inner pipe, and a part 11 is provided in the pipe plug of the inner pipe, which is a lock bar through the hook 9. It is fixedly connected to 8; a spring 1 2 and a ball 13 are provided in the pipe plug 10 of each pipe, and a spring 1 is provided between the annular convex base 15 formed on the part 11 and the upper part of the pipe plug 10. 2 is placed. The ball 13 is placed in a hole made in the wall of the pipe stopper and on the part ring convex base 15. The cross section of the annular convex base 15 described above is a trapezoid.

The wall of the outer pipe has a hole 14 corresponding to the pipe plug wall hole position, the diameter of the hole 14 is smaller than the ball 13.

As shown in FIG. 4, a spiral gear 23 is provided on each caster 21, a spring 22 is fitted in the spiral gear 23, and the swivel pipe 31 mounted on the vehicle body has the spiral shape. It is linked to gear 23.

As shown in Fig. 3, when the utility model is folded and the loading platform 1 is opened by hand, the loading platform and the vehicle body 3 are unfolded, and at the same time, the screws 5 have a constant curve, so that the casters are driven. Along with this, the spring 22 in the spiral gear 23 is compressed. Since there is a swivel pipe 31 fixed to the vehicle body, the spiral gear 23 can realize caster deployment as shown in Fig. 2 by interlocking the casters along the rotation direction of the swivel pipe 31.

When adjusting the height of the three-stage telescopic pipe, if the open / close button 72 of the switchgear is grasped upward, the lock bar 8 moves up and the hook 9 interlocks the part 11 in the pipe stopper 10. , The spring 1 2 is compressed, the two balls 13 in the pipe plug 10 are pulled, and the annular convex base 15 returns to the concave position below. At this time, the ball 13 is separated from the connection point between the pipe plug 10 and the pipe, and the multi-stage pipe can now be extended to an appropriate position. When the open / close button 72 is released, the elastic action of the spring 12 causes the trapezoidal annular convex base 15 to keep pushing the ball 13 into the outer pipe wall until the ball 13 falls into the hole 14 provided on the outer pipe wall. Since the diameter of the hole 14 is smaller than that of the ball 13, the ball 13 is surely caught in the hole 14, and the length of the multi-stage pipe can be adjusted after all.

This utility model is compact, convenient to operate and carry, and has a solid structure, so it can be applied in various cases.
