[0002] As a common food, eggs have a huge demand in daily life and commercial circulation. In order to protect eggs from being damaged during transportation and storage, various egg packaging devices have emerged. Among them, the opening and closing type egg packaging device has been widely used due to its advantages such as convenient use and easy observation of the egg state.

[0003] During transportation, the existing opening and closing type egg packaging device is prone to looseness due to factors such as vehicle bumps and vibrations, and may accidentally open. Once the packaging is opened, the eggs are easily collided and damaged, which not only affects the quality of the eggs, but may also cause economic losses and is not convenient for stacking and preventing collapse. Therefore, we urgently need to provide an opening and closing type egg packaging device.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

Detailed Description of the Embodiment

[0019] The following further elaborates on the present application in detail Figures 1-4 with reference to the attached drawings.

[0020] An embodiment of the present application discloses an opening and closing type egg packaging device. Referring to Figures 1-3 , it includes a packaging box 1. Two opening and closing covers 2 are provided at the upper end of the packaging box 1. A limiting column 5 is fixedly connected to the upper end of one of the opening and closing covers 2. A sliding rail 6 is opened at the upper end of the other opening and closing cover 2. A slider 7 is slidably connected to the inner side of the sliding rail 6. A return spring 8 is fixedly connected to the side of the slider 7. The other end of the return spring 8 is fixedly connected to the inner surface of the sliding rail 6. A rotating shaft 9 is rotatably connected to the upper end of the slider 7. A connecting rod 10 is fixedly connected to the surface of the rotating shaft 9. The other end of the connecting rod 10 is fixedly connected to a hook 11. The inner surface of the hook 11 is connected to the middle of the outer surface of the limiting column 5. When closing the opening and closing cover 2, the connecting rod 10 rotates around the rotating shaft 9 and pushes the slider 7 to move towards the side of the return spring 8. When the hook 11 is connected to the surface of the limiting column 5, the connecting rod 10 is released. The slider 7 is tightened under the elastic return of the return spring 8, realizing the firm locking of the two opening and closing covers 2, ensuring the safety of eggs during transportation and storage. When opening the opening and closing cover 2, the hook 11 is pulled. The hook 11 drives the rotating shaft 9 to rotate through the connecting rod 10. At the same time, the slider 7 slides in the sliding rail 6 and compresses the return spring 8, so that the hook 11 disengages from the limiting column 5, and the opening and closing cover 2 can be opened. Two L-shaped connecting blocks 12 are respectively fixedly connected to the upper ends of the two opening and closing covers 2. A plurality of fitting blocks 13 are evenly and fixedly connected to the four corners of the bottom of the packaging box 1. A card slot 14 is opened on the surface of the plurality of fitting blocks 13. The plurality of L-shaped connecting blocks 12 are respectively clamped inside the card slot 14. When a plurality of packaging boxes 1 are stacked, the fitting blocks 13 at the bottom of the upper packaging box 1 are embedded in the card slots 14 clamped by the L-shaped connecting blocks 12 of the lower packaging box 1. The shape matching of the fitting blocks 13 and the card slots 14 and the clamping effect of the L-shaped connecting blocks 12 limit the movement of the packaging box 1 in the horizontal and vertical directions, so that the packaging boxes 1 can be stably stacked together, improving the space utilization rate and facilitating warehousing and transportation.

[0021] Referring to Figures 2-4, a foam cushion 3 is fixedly connected to the bottom of the inner surface of the packing box 1. A plurality of arc-shaped grooves are evenly formed in the upper end of the foam cushion 3. Sponge energy-absorbing layers 4 are fixedly connected to the inner surfaces of the two opening and closing covers 2. The bottom of the sponge energy-absorbing layer 4 corresponds to the upper end of the foam cushion 3. During transportation, the foam cushion 3 and the sponge energy-absorbing layer 4 can play a buffering role for the eggs, reducing the damage caused to the eggs by vibration and collision, effectively protecting the integrity of the eggs. A plurality of grooves 15 are evenly formed in the bottoms of both sides of the packing box 1. Fixing rods 16 are fixedly connected to the bottoms of the plurality of grooves 15. A plurality of connecting rings 17 are evenly fixedly connected to the bottom of the two opening and closing covers 2. The inner sides of the plurality of connecting rings 17 are respectively rotatably connected to the surfaces of the fixing rods 16. The opening and closing covers 2 are hingedly connected to both sides of the packing box 1 through the connecting rings 17, so that the opening and closing covers 2 can be stably connected to the packing box 1, facilitating the opening and closing operations, and can maintain a relatively stable position during transportation, reducing the influence on the overall structure of the packaging device due to shaking.

[0022] The implementation principle of an opening and closing type egg packaging device according to an embodiment of the present application is as follows: During specific use, first place the eggs in the arc-shaped grooves of the foam cushion 3 at the bottom of the inner surface of the packing box 1, and then close the two opening and closing covers 2. During the closing process, the connecting rod 10 rotates around the rotating shaft 9 and pushes the slider 7 to move towards the side of the return spring 8 in the slide rail 6. When the hook 11 contacts and connects to the surface of the limit post 5, release the connecting rod 10. The slider 7 is tightened under the rebounding action of the return spring 8, thereby firmly locking the two opening and closing covers 2. When it is necessary to open the opening and closing cover 2, pull the hook 11. The hook 11 drives the rotating shaft 9 to rotate through the connecting rod 10. At the same time, the slider 7 slides in the slide rail 6 and compresses the return spring 8, so that the hook 11 disengages from the limit post 5, and the opening and closing cover 2 can be opened. During transportation, the foam cushion 3 and the sponge energy-absorbing layer 4 play a buffering and protective role for the eggs. At the same time, the locking structure of the opening and closing cover 2 prevents the packaging device from loosening and opening. When a plurality of packing boxes 1 need to be stacked, the fitting blocks 13 and the card slots 14 at the bottom of the packing box 1 and the L-shaped connecting blocks 12 and the grooves 15 on the opening and closing cover 2 cooperate with each other, so that the packing boxes 1 can be stably stacked together.
