[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] See also Figure 1-5 The utility model provides a technical solution: an expandable tailboard structure for a truck, comprising a tailboard body 1, a storage groove 7 fixedly connected to the lower surface of the tailboard body 1, an expansion plate 8 is provided at the rear end of the storage groove 7 for pulling out, a handle 9 is fixedly connected to the rear end of the expansion plate 8, and a second reinforcing rib 10 is fixedly connected between the end of the handle 9 and the surface of the expansion plate 8.

[0024] The lower surface of the receiving groove 7 is provided with a clamping structure for fixing the expansion board 8 after being pulled out, and connecting parts 6 are provided on both sides of the front end of the tail board body 1.

[0025] A plurality of first reinforcement blocks 2 are transversely fixedly connected to the lower surface of the tailgate body 1 , and the plurality of first reinforcement blocks 2 are evenly spaced and arranged along the length direction of the tailgate body 1 .

[0026] The second reinforcement blocks 3 are fixedly connected to both sides of the lower surface of the tailgate body 1 , and the third reinforcement block 4 is fixedly connected to the rear end of the lower surface of the tailgate body 1 in a transverse direction.

[0027] The clamping structure includes two accommodating boxes 11, which are respectively fixedly connected to the two sides of the rear end of the lower surface of the storage groove 7. The inner cavity of the accommodating box 11 has a sliding plate 13 that slides in the vertical direction, and the upper surface of the sliding plate 13 is fixedly connected with a clamping block 14.

[0028] The top end of the clamping block 14 is pulled out and extended to the inside of the receiving groove 7 , a spring 16 is vertically fixedly connected between the upper surface of the sliding plate 13 and the top of the inner wall of the receiving box 11 , and a handle 12 is fixedly connected to the lower surface of the sliding plate 13 .

[0029] The bottom of the pull handle 12 is pulled out and extended to the outside of the storage box 11. Both ends of the front side of the lower surface of the expansion plate 8 are provided with second snap-in sockets 17 adapted to the snap-in block 14, and both ends of the rear side of the lower surface of the expansion plate 8 are provided with first snap-in sockets 15 adapted to the snap-in block 14.

[0030] After the handle 12 is pulled to drive the sliding plate 13 to move, the clamping block 14 can be driven to descend. When the clamping block 14 is retracted to the inner cavity of the accommodating box 11, the expansion plate 8 can be pulled by the handle 9 to move.

[0031] When the expansion plate 8 is moved to the outside of the storage slot 7, the load-bearing area of ​​the tailgate body 1 is expanded, so that it can carry more cargo and can be adapted to a longer manual transport truck for carrying, thereby improving the safety and stability during cargo handling, facilitating truck loading and unloading, and improving the safety of the staff's handling operations.

[0032] After the expansion plate 8 is pulled to move to the outside, the elastic force of the spring 16 drives the clamping block 14 to embed into the inner wall of the second bayonet 17, so as to limit and fix the expansion plate 8 after movement, thereby improving the stability during the load-bearing process.

[0033] The connection between the first reinforcement block 2 , the second reinforcement block 3 and the third reinforcement block 4 improves the overall strength of the tailgate body 1 , improves the stability of the tailgate body 1 during operation, and extends the service life of the tailgate body 1 .

[0034] Furthermore, a plurality of first reinforcing ribs 5 are fixedly connected between the side wall of the third reinforcing block 4 and the lower surface of the tailgate body 1 . The first reinforcing ribs 5 can effectively improve the bearing strength of the tailgate body 1 .

[0035] Furthermore, an anti-skid pad 21 is fixedly connected to the upper surface of the tailgate body 1 , and an anti-skid pattern is provided on the upper surface of the anti-skid pad 21 .

[0036] In this embodiment, the anti-slip pad 21 improves the anti-slip property of the manual transport vehicle after it moves to the upper surface of the tailgate body 1 , thereby improving the stability during the transport process.

[0037] Furthermore, the front and rear sides of both end surfaces of the expansion plate 8 are rotatably connected to rollers 18, and both sides of the inner wall of the storage groove 7 are provided with sliding grooves 19 for the rollers 18 to slide.

[0038] In this embodiment, when the expansion board 8 is pulled out and moved, the roller 18 is driven to slide inside the slide groove 19, guiding and limiting the expansion board 8 during movement, thereby improving the stability and smoothness of the expansion board 8 during movement.

[0039] Furthermore, a reflective sticker 20 is fixedly connected to the lower surface of the first reinforcement block 2. The reflective sticker 20 is convenient for providing reflective warning at night after the tailgate body 1 is folded and closed.

[0040] The working principle and usage process of the present invention: After the present invention is installed, the handle 12 is pulled to drive the sliding plate 13 to move, which can drive the clamping block 14 to descend. When the clamping block 14 shrinks to the inner cavity of the accommodating box 11, the expansion plate 8 can be pulled by the handle 9 to move. When the expansion plate 8 moves to the outside of the storage slot 7, the bearing area of ​​the tailgate body 1 is expanded, so that it can carry more goods and can be adapted to a longer manual transport vehicle for carrying, thereby improving the safety and stability during the cargo handling process, facilitating the loading and unloading of trucks, and improving the safety of the staff's handling operations. After pulling the expansion plate 8 to the outside, the elastic force of the spring 16 drives the clamping block 14 to embed into the inner wall of the second bayonet 17, so that the expansion plate 8 can be limited and fixed after movement, thereby improving the stability during the bearing process.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
