DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] The utility model provides Figure 1-Figure 5 A double-layer blister tray that can prevent items from falling off is shown, including a first tray 1, a second tray 11 is arranged above the first tray 1, and the upper surfaces of the first tray 1 and the second tray 11 are both provided with tray grooves 2 for placing items, one end of the first tray 1 and the second tray 11 is fixedly connected to a rotating block 4, the rotating block 4 on the first tray 1 is fixedly connected to the lower end of the support shaft 5, and the rotating block 4 on the second tray 11 is rotatably arranged at the upper end of the support shaft 5, the first tray 1 and the second tray 11 form a double-layer tray structure for accommodating items, and the second tray 11 can rotate on the support shaft 5, so that the first tray 1 can be conveniently covered or opened to facilitate the storage of items.

[0024] A first card plate 7 is fixedly provided on the lower surface of the second tray 11, and a first card slot 3 is provided on the upper surface of the first tray 1. The first card slot 3 and the first card plate 7 are engaged and fixed with each other. The first card plate 7 is an elastic rubber strip structure. When the second tray 11 rotates, it can be engaged in the corresponding first card slot 3 through the first card plate 7, which facilitates the positioning between the first tray 1 and the second tray 11, making it difficult for the second tray 11 to detach from the first tray 1, thereby preventing the items stored in the tray structure from falling off.

[0025] It should be noted that two first card slots 3 are provided, and the two first card slots 3 are respectively provided at two ends of the upper surface of the first tray 1 , so as to facilitate the stable positioning of the first tray 1 and the second tray 11 .

[0026] A second card slot 8 is provided on the upper surface of the second tray 11. A cover plate 6 is provided above the second tray 11. The cover plate 6 is slidably connected to the second card slot 8. The cover plate 6 can slide on the second card slot 8, thereby covering the tray slot 2 on the second tray 11, making it convenient to store items in the tray slot 2 of the second tray 11.

[0027] In actual setting, a buffer rubber pad is fixedly arranged on the bottom surface of the tray slot 2, so that the articles placed in the tray slot 2 have good buffering performance.

[0028] Taking into account that the second tray 11 can rotate around the support shaft 5, when the second tray 11 rotates to the top of the first tray 1, in order to increase the relative stability of the first tray 1 and the second tray 11, it is necessary to position the second tray 11. Therefore, a positioning mechanism is provided on the rotating block 4 at one end of the second tray 11. The positioning mechanism includes a limit pin slot 14 and a limit pin plate 10. A circular hole is provided in the middle of the rotating block 4, which penetrates the upper and lower surfaces of the rotating block 4 at the same time. The circular hole is for the support shaft 5 to movably pass through. The limit pin slot 14 is connected between the outer side surface of the rotating block 4 and the inside of the circular hole. The limit pin plate 10 is slidably connected in the limit pin slot 14; the support shaft 5 corresponds to the side surface of the second tray 11 The upper and lower positions are disconnected, and a limit column 9 is set at the disconnected position. There are multiple limit columns 9, and the multiple limit columns 9 are distributed in a ring array. The upper and lower ends of the limit columns 9 are respectively fixedly connected to the upper and lower structures of the disconnected position of the support shaft 5. The multiple limit columns 9 are all located in the circular hole inside the rotating block 4, and a gap is formed between adjacent limit columns 9 for the limit pin plate 10 to be engaged and connected; during operation, when the second pallet 11 rotates to above the first pallet 1, the limit pin plate 10 is inserted into the corresponding gap from the limit pin slot 14 to achieve positioning between the first pallet 1 and the second pallet 11. When the end of the limit pin plate 10 moves out of the corresponding gap, the second pallet 11 can continue to rotate.

[0029] Because the second tray 11 can rotate around the support shaft 5, and the tray slot 2 inside the second tray 11 is used to store items, the weight of the items will press the end of the second tray 11 away from the support shaft 5 to tilt downward. When the items are heavy, the end of the second tray 11 away from the support shaft 5 may be excessively squeezed and contacted with the upper surface of the first tray 1, causing the second tray 11 to be difficult to rotate. Therefore, a telescopic slot 12 is provided inside the end of the second tray 11 away from the rotating block 4, and a support rod 13 is slidably provided inside the telescopic slot 12. The upper end of the support rod 13 is fixedly connected with a spring 15, and the spring 15 is fixedly connected to the upper end inner wall of the telescopic slot 12, and the lower end of the support rod 13 is movably fitted to the upper surface of the first tray 1; the spring 15 supports the telescopic slot 12 to contact the upper surface of the first tray 1, and has an elastic supporting effect on the end of the second tray 11 away from the support shaft 5, thereby preventing the end of the second tray 11 away from the support shaft 5 from being excessively pressed against the upper surface of the first tray 1, thereby ensuring that the second tray 11 can smoothly rotate around the support shaft 5.

[0030] Furthermore, the end of the support rod 13 that fits the upper surface of the first tray 1 is a hemispherical structure. There is point contact between the hemispherical structure and the upper surface of the first tray 1, so the damping is small. When the second tray 11 rotates, it is smoother and less likely to cause wear to the upper surface of the first tray 1, so it has a long service life.
