Both sides of the surface of the connecting rod 11 are installed The reset mechanism 12 can return the movable frame 8 to its original position after it moves, so as to facilitate the subsequent movement of the first blocking door 3 and the second blocking door 4. The bottom of the lower movable frame 8 is rotatably connected with a pedal 13. One side of the first blocking door 3 and the second blocking door 4 is fixedly connected with a limit plate 14. The pedal 13 is used in conjunction with the limit plate 14. Under this action, the staff can move the two movable frames 8 by stepping on the pedal 13, so as to facilitate the control of the positioning mechanism 10, and the pedal 13 can be limited with the cooperation of the limit plate 14, so that the movable frame 8 will not move at will.
[0023] The locking mechanism 7 includes a fixing plate 71, the surface of which is fixedly connected to the surface of the mounting block 6, a pin rod 72 is fixedly connected to one side of the fixing plate 71, and the number of the pin rods 72 is several. A connecting shell 73 is fixedly connected to one side of the second blocking door 4, and the number and position of the connecting shells 73 correspond to the pin rods 72. The surface of the pin rod 72 is slidably connected to the inner wall of the connecting shell 73. Under this action, the first blocking door 3 and the second blocking door 4 can be connected, so that the first blocking door 3 and the second blocking door 4 will not rotate at will, thereby improving the blocking effect on the goods.
[0024] The positioning mechanism 10 includes a slider 101, the surface of which is slidably connected to the inner wall of the connecting groove 9, and the cross-sectional shape of the connecting groove 9 is a T-shaped structure design. Under this action, the slider 101 will not be easily detached from the inside of the connecting groove 9, effectively improving the stability of the slider 101. A movable rod 102 is fixedly connected to one side of the slider 101, and two locations on both sides of the inner cavity of the cargo box body 1 are fixedly connected to positioning shells 103. The inner wall of the positioning shell 103 is slidably connected to the surface of the movable rod 102. Under this action, the first blocking door 3 and the second blocking door 4 can be limited by the movable rod 102, so that the first blocking door 3 and the second blocking door 4 will not rotate and move easily, effectively improving the stability of the first blocking door 3 and the second blocking door 4. The surface of the movable rod 102 is slidably connected to the limiting sleeve, and the limiting sleeve is fixedly connected to the surface of the first blocking door 3 and the second blocking door 4. Under this action, the movable rod 102 can be limited and guided, so that it will not move at will.
[0025] The reset mechanism 12 includes a fixed shell 121, one side of which is fixedly connected to the surfaces of the first blocking door 3 and the second blocking door 4, and a connecting plate 122 is slidably connected to the inner cavity of the fixed shell 121. One side of the connecting plate 122 is fixedly connected to the surface of the connecting rod 11, and a compression spring 123 is fixedly connected to the surface of the connecting plate 122. The other end of the compression spring 123 is fixedly connected to the inner wall of the fixed shell 121. Under this action, the connecting rod 11 can drive the connecting plate 122 to move, and the connecting rod 11 can return to its original position with the cooperation of the compression spring 123. , so that the movable frame 8 can return to its original position. The inner wall of the fixed shell 121 is fixedly connected with a guide rod 15, and the other end of the guide rod 15 passes through the other side of the connecting plate 122 and is slidably connected to the inner wall of the passing point. Under this action, the connecting plate 122 can be guided when it moves, so that the connecting plate 122 can move more stably. The guide rod 15 is located inside the compression spring 123. Under this action, the compression spring 123 can be more stable when compressed or rebounded, avoiding the displacement of the compression spring 123 and affecting the movement effect of the connecting plate 122.
[0026] It is worth noting that the technical features such as the cargo box body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.
[0027] Working principle: first, install the cargo box body 1 on the beam of the truck, and then place the cargo inside the cargo box body 1. After the cargo is placed, the staff pushes the first blocking door 3 and the second blocking door 4 in turn, and with the cooperation of the installation track 2, the first blocking door 3 and the second blocking door 4 are close to the cargo. Then the staff steps on the pedal 13, and under the action of the pedal 13, the slider 101 is pushed to move through the cooperation of the movable frame 8 and the connecting rod 11 and the connecting groove 9. Then, under the action of the slider 101, the movable rod 102 is embedded in the interior of the positioning shell 103 to limit the first blocking door 3. Then, the pedal 13 is rotated to make it contact with the limiting plate 14 to prevent the movable rod 102 from returning to its original position, and then the second blocking door 4 is fixed. Then, the staff pushes the fixing plate 71 to drive the pin rod 72 to embed into the interior of the connecting shell 73, so as to connect the first blocking door 3 and the second blocking door 4.
