[0030] 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.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment of a foldable plastic turnover box, comprising a box body 1, the inner wall of the box body 1 is slidably connected to the installation box 2, the inner wall of the box body 1 is provided with a slide groove, which can allow the installation box 2 to slide up and down, the box body 1 and the installation box 2 constitute the entire turnover box, and some turnover boxes are mainly used in the field of logistics, which can protect the goods from damage and pollution, help optimize the packaging and loading of goods, reduce space waste, and improve loading efficiency. The right end side wall of the box body 1 is fixedly connected with a handle 3, and the outer wall of the handle 3 is provided with a notch, which is convenient for the staff to hold the handle 3 to carry the box body 1. The inner wall of the handle 3 is provided with a limiting mechanism, the right end side wall of the box body 1 is provided with a short transverse groove 7, the plug block 6 matches the short transverse groove 7, and can allow the plug block 6 to move horizontally in the short transverse groove 7, and the right end side wall of the installation box 2 is provided with an L groove 8, the L groove 8 is divided into a vertical opening and a transverse opening, which can enable the plug block 6 to slide vertically in the vertical opening. After the plug block 6 coincides with the transverse opening, the installation box 2 is limited.

[0032] Reference Figure 3The cam 6 is connected to the inner wall of the handle 3 and the cam 6 is connected to the inner wall of the handle 3 so that the cam 6 can move left and right.

[0033] Reference Figure 1 、 Figure 4 and Figure 5 The outer wall of the box body 1 is fixedly connected with a fixed block 12, and the outer wall of the box body 1 is fixedly connected with a limited plate 9. A short transverse groove 7 is provided on the limited plate 9, which allows the inclined block 11 to move laterally in the short transverse groove 7. The inner wall of the right end of the limited plate 9 is elastically connected with the inclined block 11 through the return spring 10. The left end side wall of the inclined block 11 is an inclined surface. When the inclined block 11 is squeezed, the inclined block 11 will move laterally on the inner wall of the limited plate 9. The inclined block 11 passes through and is slidably connected to the inner wall of the limited plate 9. The fixed block 12 is hollow and can meet the requirements of the limited plate 9. According to the requirements, the inner wall of the right end of the limit plate 9 is fixedly connected to one end of the return spring 10, and the other end of the return spring 10 is fixedly connected to the right end side wall of the inclined block 11. When the inclined block 11 is moved to the right by hand, the return spring 10 is squeezed. When resetting, the reverse action of the return spring 10 is used to push the inclined block 11 to move to the left. The limit plate 9 is plugged into the inner wall of the fixed block 12, and the inclined block 11 contacts the upper and lower ends of the fixed block 12. The inclined block 11 returns to its initial state under the elastic force of the return spring 10. Figure 5 A notch is provided at the bottom of the box body 1 so that the top of the installation box 2 can be plugged into the notch when two turnover boxes are stacked.

[0034] Working principle: First, when the loading space of the installation box 2 needs to be adjusted, just pull up the installation box 2 to make the insert 6 and the L-slot 8 slide relative to each other. When the insert 6 coincides with the horizontal opening of the L-slot 8, since the positioning spring 4 is initially in a compressed state, the insert 6 moves to the right under the elastic force of the positioning spring 4, so that the insert 6 is stuck on the inner wall of the horizontal opening of the L-slot 8, completing the position limit of the installation box 2 and the box body 1. It is necessary to restore the position of the installation box 2 to Figure 1As shown, you only need to use your hand to push the raised part of the pull column block 5 to the left, so that it drives the insert block 6 to move to the left, and separate the insert block 6 from the horizontal opening of the L-slot 8. At this time, the insert block 6 coincides with the vertical opening of the L-slot 8, and the positioning spring 4 is in a compressed state. At the same time, let the staff press the installation box 2 downward to make the pull column block 5 slide relative to the inner wall of the vertical opening of the L-slot 8. Finally, loosen the pull column block 5, so that the insert block 6 is squeezed on the inner wall of the vertical opening of the L-slot 8, so that the positioning spring 4 is in a compressed state, thereby completing the change of the loading capacity of the turnover box.

[0035] When multiple boxes 1 need to be stacked and fixed, it is only necessary to insert the limit plate 9 into the inner wall of the fixed block 12, and let the bottom end of the fixed block 12 squeeze the inclined surface of the inclined block 11, so that the inclined block 11 moves to the right. At this time, the return spring 10 is in a compressed state. When the inclined block 11 is not in contact with the fixed block 12, the inclined block 11 moves to the left under the elastic force of the return spring 10 to reset, and let the bottom end of the inclined block 11 contact the top of the fixed block 12, so that the inclined block 11 blocks the fixed block 12. When the boxes 1 need to be separated, it is only necessary to move the inclined block 11 to the right to compress the return spring 10, and at the same time let the staff hold the box 1 and move upward to separate the two groups of boxes 1. When the inner wall of the fixed block 12 is no longer in contact with the outer wall of the inclined block 11, loosen the inclined block 11 to restore the spring to its original state, and complete the stacking and separation of the turnover boxes.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
