[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0024] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0027] See also Figure 1-7 , the utility model provides a technical solution:

[0028] A guide sliding mechanism for an extended plate of a truck cargo box comprises a car body 1, a mounting frame 2 mounted on the inner side of the car body 1 and an extended plate body 3 arranged on the inner side of the mounting frame 2. The outer side of the mounting frame 2 is detachably connected to a connecting frame 4 with an inverted U-shaped cross-section by bolts. A fixing plate 5 is fixedly connected to the inner wall of the connecting frame 4. A limiting groove 7 is provided on the inner side of the fixing plate 5. A sliding groove 6 connected to the limiting groove 7 is provided on the side of the fixing plate 5 away from the inner wall of the connecting frame 4. The inner side of the limiting groove 7 is slidably connected to a limiting block 8. A slider 9 is fixedly connected to the outer side of the limiting block 8. A positioning plate 11 is fixedly connected to the side of the slider 9 away from the limiting groove 7. The positioning plates 11 are symmetrically arranged on both sides of the extended plate body 3 and fixedly connected to the extended plate body 3.

[0029] The slider 9 is arranged on the inner side of the slide groove 6 and is slidably connected with the slide groove 6. The slider 9 is symmetrically arranged. This arrangement enables the slider 9 to slide together with the positioning plate 11 to guide the positioning plate 11; the top and bottom of the positioning plate 11 are provided with grooves 12 of equal groove diameters, and the inner side of the groove 12 is provided with a spring 13. The inner side of the groove 12 is slidably connected with a block 14 with an arc-shaped arrangement on one side. The top and bottom of the connecting frame 4 are provided with grooves 10 of equal groove diameters, and the one side of the block 14 is arc-shaped and engages with the inner side of the groove 10. This arrangement makes it possible for the extension of the extension drag plate body 3 to be completed when the block 14 engages with the inner side of the groove 10; the two ends of the spring 13 are fixedly connected to the inner wall of the groove 12 and the block 14 respectively, and the spring 13 is evenly arranged. This arrangement enables the spring 13 to be used in conjunction with the block 14, and the elastic force generated by the compression of the spring 13 makes the block 14 fit more closely with the groove 10. The sliding groove 6 and the limiting groove 7 arranged on the inner side of the fixing plate 5 are opened at one end away from the card groove 10. This arrangement allows the limiting block 8 and the slider 9 to be separated from the limiting groove 7 and the sliding groove 6 respectively, thereby realizing the disassembly of the extension drag plate body 3.

[0030] When the extension plate body 3 is to be slid and extended, the extension plate body 3 is pulled so that the extension plate body 3 drives the positioning plate 11 and the fixed plate 5 to slide relative to each other. At this time, the positioning plate 11 drives the slider 9 to slide on the inside of the slide groove 6, and the slider 9 drives the limit block 8 to slide on the inside of the limit groove 7. The cooperation of the limit block 8 and the limit groove 7 ensures that the slider 9 will not separate from the slide groove 6 when sliding with the positioning plate 11, so that the extension plate body 3 can slide stably under the cooperation guide of the slider 9 and the slide groove 6. When the block 14 is engaged with the inner side of the slot 10, it indicates that the extension of the extension plate body 3 is completed. In this process, the block 14 will be acted upon by the inner wall of the connecting frame 4, so that the block 14 will slide on the inside of the groove 12 and act on the spring 13, so that the spring 13 is compressed. When all the blocks 14 are moved to the inside of the slot 10, the elastic force generated by the compression of the spring 13 will make the blocks 14 fit more closely with the slot 10, thereby achieving the positioning of the positioning plate 11 and the extension carriage body 3. When the extension carriage body 3 is to be disassembled, the bolts connecting the connecting frame 4 and the mounting frame 2 are removed by a tool, and the connecting frame 4 together with the positioning plate 11 and the extension carriage body 3 can be separated from the car 1. Then, the extension carriage body 3 is pushed away from the slot 10, so that the limit block 8 and the slider 9 move away from the slot 10. When the limit block 8 and the slider 9 are respectively separated from the limit groove 7 and the slide groove 6, the extension carriage body 3 is disassembled and can be repaired. The reverse operation can be performed to achieve the installation of the extension carriage body 3.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
