[0007] Furthermore, a set of mating holes are connected to the front side of the slide groove, and a mating groove is connected to the front side of the mating holes. A first wedge block is slidably installed on the left side of the mating groove, and a second wedge block is mated and installed on the right rear side of the first wedge block. The second wedge block is slidably installed inside the mating groove, and a positioning post is fixedly installed on the rear side of the second wedge block. The positioning post is slidably installed in the mating holes.

[0008] Furthermore, a set of positioning holes is provided at the front end of the slide rail, and the positioning holes are installed in conjunction with the positioning posts.

[0009] Furthermore, two sets of second springs are fixedly installed at the front end of the rear inner wall of the mating groove, and the ends of the second springs are fixedly connected to the second wedge block.

[0010] Furthermore, a rotating shaft is movably mounted on the left side of the first wedge block via a bearing, and a nut is fixedly mounted on the outer side of the left end of the rotating shaft.

[0011] Furthermore, a set of threaded holes is provided on the left side of the mating groove, and a threaded part is provided in the middle of the rotating shaft, the threaded part being installed in conjunction with the threaded holes.

[0012] The beneficial effects of this utility model are as follows: by inserting the slide rail into the slide groove and then rotating the rotating nut, the threaded part and the threaded hole are rotated to make the first wedge block be pushed to the right, so that the second wedge block moves upward, and finally the positioning pin is inserted into the positioning hole to complete the positioning and fixing of the slide rail, preventing it from falling off during movement. Through the double buffering of the rubber pad and the first spring, the car body is protected, and the cargo loaded inside the car body is buffered and protected during movement.

Car body Detailed Implementation

[0021] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0022] like Figures 1 to 6 As shown, this utility model includes a platform 1, a cargo box 21 is provided above the platform 1, two sets of sliding grooves 2 are provided on the rear side of the platform 1, slide rails 6 are slidably installed in the slide grooves 2, a moving groove 7 is provided inside the rear side of the slide rails 6, and mounting columns 8 are slidably installed in the moving grooves 7. A first spring 9 is fixedly installed on the front side wall inside the moving groove 7, and the mounting column 8 is fixedly installed at the end of the first spring 9. C-shaped frames 11 are fixedly installed at the rear ends of the two sets of mounting columns 8. A set of side baffles 12 is provided on each of the left and right sides of the C-shaped frame 11. Rubber pads 13 are fixedly installed on the side baffles 12 and the outer side of the C-shaped frame 11. The C-shaped frame 11 is located at the rear end of the platform 1 and can protect the two rear corners. In use, the double buffering of the rubber pads 13 and the first springs 9 protects the platform 1 and provides buffer protection for the movement of the goods loaded inside the cargo box 21.

[0023] like Figures 1 to 4 As shown, a set of mating holes 3 are connected to the front side of the slide groove 2, and a mating groove 4 is connected to the front side of the mating holes 3. A set of threaded holes 5 are provided on the left side of the mating groove 4. A first wedge block 14 is slidably installed on the left side of the mating groove 4. A rotating shaft 15 is movably installed on the left side of the first wedge block 14 via a bearing. A nut 17 is welded to the outer side of the left end of the rotating shaft 15. A threaded part 16 is provided in the middle of the rotating shaft 15. The threaded part 16 is fitted with the threaded hole 5. By rotating the nut 17, the threaded part 16 is rotated in conjunction with the threaded hole 5, thereby adjusting the first wedge block 14. A wedge block 14 is pushed to the right, and a second wedge block 18 is installed on the right rear side of the first wedge block 14. The second wedge block 18 is slidably installed inside the mating groove 4, so that the second wedge block 18 moves upward. A positioning post 20 is fixedly installed on the rear side of the second wedge block 18. The positioning post 20 is slidably installed in the mating hole 3. A set of positioning holes 10 is provided at the front end of the slide rail 6. The positioning holes 10 are installed in conjunction with the positioning post 20, so that the positioning post 20 is inserted into the positioning hole 10 to complete the positioning and fixing of the slide rail 6 and prevent it from falling off during movement.
