Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 5 As shown, the utility model provides a stretchable plastic turnover box, including a turnover box body 1, a pull-out plate 2 is slidably arranged inside the turnover box body 1, a baffle 3 is fixedly arranged on the right side of the pull-out plate 2, and the baffle 3 is pulled to pull the pull-out plate 2 out of the turnover box body 1 to form a larger turnover box body 1 for storing items, and the top of the turnover box body 1 also includes a cover plate stretching assembly 10;

[0026] The cover plate stretching assembly 10 includes a cover plate 101 rotatably arranged with the turnover box 1, and a torsion spring winding box 102 is rotatably arranged at the top of the cover plate 101. The torsion spring winding box 102 can be wound by the torsion spring to pull out the flexible cloth 103. The flexible cloth 103 is wound inside the torsion spring winding box 102, and a stopper 104 is fixedly arranged at the other end of the flexible cloth 103. The stopper 104 structure serves as a counterweight pulling structure to pull the flexible cloth 103 out from the inside of the torsion spring winding box 102.

[0027] Specifically, both the front and rear sides of the turnover box 1 are provided with a slide groove 5, a slider 4 is slidably arranged inside the slide groove 5, and the slider 4 is fixed to the pull-out plate 2. The turnover box 1 can move inside the slide groove 5 through the slider 4 to perform a stable unfolding operation.

[0028] Furthermore, a positioning buckle 6 is fixedly provided at a corner of the top of the turnover box body 1, and an insert plate 7 is rotatably provided inside the positioning buckle 6. A first positioning shaft 8 is fixedly provided on the side of the insert plate 7 facing the cover plate 101, and the first positioning shaft 8 is plugged into the cover plate 101. By rotating the insert plate 7, the first positioning shaft 8 can be inserted into the interior of the cover plate 101 for quick positioning.

[0029] Furthermore, a spring 9 is fixedly provided on the outer side of the plug plate 7 , and the spring 9 is fixedly provided with the positioning buckle 6 , and the spring 9 can pull the plug plate 7 to maintain a position close to the outer side of the positioning buckle 6 .

[0030] It is worth noting that a rotating fork frame 105 is rotatably provided at the bottom end of the stopper 104 , and the rotating fork frame 105 is slidably provided with the cover plate 101 , and the rotating fork frame 105 is controlled to control the stopper 104 to be stably unfolded.

[0031] It is worth noting that a positioning hook 106 is rotatably provided on the outer side of the stopper 104, and a second positioning shaft 107 is fixedly provided on the top right side of the baffle 3. The positioning hook 106 can be rotatably connected to the outer side of the second positioning shaft 107 to form a limiting structure to keep the pull-out plate 2 closed after opening.

[0032] Among them, the turnover box 1 is the existing technology and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0033] Working principle and process:

[0034] When the staff uses the turnover box 1 to transport items, they can directly open the cover plate 101 in the cover plate stretching assembly 10 and put the items into the turnover box 1 for storage. If the items to be placed are large and the storage space of the turnover box 1 needs to be increased, the baffle 3 can be pulled to pull out the built-in pull-out plate 2 from the inside of the turnover box 1, and the turnover box 1 can be unfolded to increase the storage space of the turnover box 1 to store larger items. When the pull-out plate 2 moves inside the slide groove 5 of the turnover box 1 through the outer slider 4, a stable effect can be maintained to avoid deviation of the pull-out plate 2 of the expanded structure of the turnover box 1. After the items are stored, the cover plate 101 structure in the cover plate stretching assembly 10 can be rotated to seal the turnover box 1. After the sealing is completed, the staff rotates the torsion spring winding box 102. The torsion spring winding box 102 can be rotated to After the rotating fork frame 105 is rotated and opened, the stopper 104 can drive the flexible cloth 103 to stretch and unfold from the inside of the torsion spring winding box 102. After the flexible cloth 103 moves and unfolds, it can cover the remaining space above the pull-out plate 2. When it is unfolded and close to the baffle plate 3, the positioning hook 106 on the outside of the stopper 104 can be rotated to rotate and snap the positioning hook 106 into the outside of the first positioning shaft 8 on the outside of the baffle plate 3 for quick positioning. After the assembly is completed, a sealing structure similar to the cover plate 101 above the turnover box 1 is performed above the pull-out plate 2 and the baffle plate 3 to store and seal the articles inside the turnover box 1 and the pull-out plate 2 to prevent the articles from falling out of the inside of the turnover box 1 and maintain the storage stability of the turnover box 1 during transportation.
