Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In this application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present application, it is to be understood that the terms "longitudinal," "lateral," "horizontal," "top," "bottom," "upper," "lower," "inner" and "outer" and the like are used in the orientation or positional relationship shown in the drawings, which are used for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1-6, the present invention provides a trolley, which comprises a guide rod 10, a fixed plate 20 and a movable plate 30, wherein the fixed plate 20 and the movable plate 30 form a cargo platform. The guide bar 10 is arranged in the transverse direction; the fixed plate 20 is fixedly arranged on the guide rod 10; the moving plate 30 is mounted on the guide bar 10 and slidably coupled to the guide bar 10.

The moving plate 30 and the fixed plate 20 each have an extension 40, and both overlap each other through the extension 40. When the moving plate 30 slides on the guide bar 10, the side of the moving plate 30 close to the fixed plate 20 always completely covers the fixed plate 20 due to the design of the extension portion 40. Sliding movement of the moving plate 30 changes the size of the cargo platform. Meanwhile, since the side of the moving plate 30 close to the fixed plate 20 is always completely covered on the fixed plate 20, the enlarged cargo platform does not have a large gap, so that the luggage or cargo with small volume is not easy to fall off from the cargo platform.

The bottom of the movable plate 30 and/or the fixed plate 20 is provided with a plurality of casters 21 to facilitate the movement of the trolley 60.

In one embodiment, the moving plate 30 has two pieces and is located at both sides of the fixed plate 20. This design is convenient for the user, who pushes the moving plate 30 away from the fixed plate 20 when the cargo platform needs to be enlarged.

In one embodiment, the guide bar 10 is formed with a plurality of positioning holes 11 along the extending direction thereof, and the moving plate 30 is mounted with the locking device 50. The locking device 50 serves to lock the position of the moving plate 30 on the guide bar 10, so that the size of the enlarged cargo platform remains stable. Specifically, the locking device 50 includes a positioning block 51 and a spring 52. The positioning block 51 is mounted on the moving plate 30, a positioning rod 53 is disposed on one side of the positioning block 51 close to the guide rod 10, and the positioning rod 53 can penetrate through the moving plate 30 and then extend into the positioning hole 11. The spring 52 is disposed on the moving plate 30, one end of the spring 52 is connected to the moving plate 30, and the other end is connected to the positioning block 51, and the positioning rod 53 tends to abut against the guide rod 10 due to the spring 52.

The specific using process is as follows: when the cargo platform needs to be enlarged, the user first pulls the positioning block 51 by hand to disengage the positioning rod 53 on the positioning block 51 from the initial positioning hole 11, and then releases the positioning block 51 after pushing the moving plate 30 to slide a short distance on the guide rod 10, at this time, the positioning rod 53 keeps abutting against the guide rod 10 under the action of the spring 52. Then, the moving plate 30 is further pushed to slide on the guide rods 10 in a direction away from the fixed plate 20, and when the positioning rod 53 slides to a position aligned with another positioning hole 11, the positioning rod 53 is inserted into the positioning hole 11 under the action of the spring 52, thereby locking the moving plate 30. The process of shrinking the cargo platform is the reverse of the above steps and will not be described in detail herein.

In one embodiment, the fixed plate 20 and/or the moving plate 30 are provided with a telescopically adjustable pull rod 60, and the pull rod 60 is movably connected with the fixed plate 20 and/or the moving plate 30. Specifically, the pull rod 60 includes a first sleeve 61, a second sleeve 62, and a U-shaped rod 63, wherein one end of the first sleeve 61 is hinged to the upper surface of the fixed plate 20 and/or the movable plate 30, one end of the second sleeve 62 is telescopically coupled to the other end of the first sleeve 61, and the U-shaped rod 63 is telescopically coupled to the other end of the second sleeve 62. Therefore, the height of the pull rod 60 can be adjusted, and the use by users with different heights is convenient.

The cargo platform is also provided with a receiving groove 70 for receiving the pull rod 60. The joint of the first sleeve 61 and the second sleeve 62 is further provided with a cross bar 64 to enhance the stability of the whole pull rod 60.

In one embodiment, the moving plate 30 is also provided with a hand grip 80. The hand-held portion 80 can be a small through hole or a handle, and when the pull rod 60 vehicle needs to be retracted, the pull rod 60 vehicle can be conveniently moved through the hand-held portion 80.

In one embodiment, the caster 21 is a universal wheel with a self-locking function. The universal wheels make the trolley 60 more flexible in use. The self-locking function can limit the rolling of the universal wheels, so that the pull rod 60 can not slide away randomly in the process of loading and unloading the cargos, and a user can load and unload the cargos conveniently.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
