Abstract
Description
Technical Field
[0001] This utility model relates to the field of egg storage technology, and in particular to a multi-layer egg box. Background Technology
[0002] An egg carton is a container used to pack and protect eggs, primarily to reduce breakage caused by shock and impact during handling and transportation. Egg cartons are designed for ease of handling, transport, and carrying.
[0003] Chinese utility model patent CN217533944U discloses an egg storage device that can be equipped with multiple trays to make full use of three-dimensional space to store more eggs. Regarding the aforementioned related technology, the inventors believe that the following defects exist:
[0004] In actual use, the upper tray needs to be flipped up to facilitate the retrieval and placement of eggs from the lower layer. After retrieving or placing eggs, the flipped tray must be reset, which increases the number of steps required to operate the device and reduces its practicality. Therefore, we provide a multi-layer egg carton. Utility Model Content
[0005] To address the problem in the aforementioned background technology where the inconvenience of quickly retrieving eggs from the lower layer or placing them on the lower tray reduces the practicality of the device, this utility model provides a multi-layer egg box.
[0006] This utility model is achieved using the following technical solution: a multi-layer egg carton, including a carton body, three sets of placement plates are equidistantly arranged inside the carton body, and placement grooves are evenly opened on the placement plates. Two sets of sliding plates are symmetrically arranged at the bottom of the inner cavity of the carton body. Two sets of sliding rods are also symmetrically fixedly connected to the bottom of the inner cavity of the carton body, and the sliding rods are slidably connected to the two sets of sliding plates at the same time. Springs are sleeved on both sides of the sliding rods. The sliding plates and the bottom placement plates are symmetrically hinged to each other by connecting rods.
[0007] As a further improvement to the above solution, a cover plate is rotatably connected to one side of the box body via a pivot, and a latch is provided on the cover plate. Two sets of handles are also symmetrically fixedly connected to the box body.
[0008] As a further improvement to the above solution, a handle is fixedly connected to the top of the upper placement plate.
[0009] As a further improvement to the above solution, movable grooves are provided on both sides of the middle and lower placement plates, and movable support columns are slidably connected inside the movable grooves. One end of the movable support column is fixedly connected to a limit plate.
[0010] As a further improvement to the above solution, arc-shaped grooves are provided on both sides of the top of the box.
[0011] As a further improvement to the above solution, adjacent sets of placement plates are fixedly connected by connecting columns.
[0012] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the inner wall of the box and the slide plate, respectively.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by removing the top layer of eggs, reduces the overall weight of the placement plate. Through the sliding cooperation between the sliding rod and the sliding plate, the spring's own rebound, and the hinged cooperation between the sliding plate, the bottom placement plate, and the connecting rod, the lower placement plate can be pushed upwards. This allows the eggs on the lower placement plate to be pushed to an easily accessible position, facilitating direct retrieval of the eggs without additional steps, thus increasing the convenience of the device.
[0015] 2. This utility model allows eggs to be placed on the bottom shelf. Due to the increased weight of the shelf, the sliding cooperation between the sliding rod and the sliding plate, the spring's own rebound, and the hinged cooperation between the sliding plate, the bottom shelf, and the connecting rod, the bottom shelf can automatically descend into the box, making it easier to place eggs on the top shelf without repeatedly flipping the shelf, thus further improving the convenience of using the device.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0022] Example 1:
[0023] Please combine Figure 1-3 The multi-layer egg carton of this embodiment includes a carton body 1. Three sets of placement plates 2 are equidistantly arranged inside the carton body 1. Placement slots 3 are evenly distributed on the placement plates 2. Two sets of sliding plates 4 are symmetrically arranged at the bottom of the inner cavity of the carton body 1. Two sets of sliding rods 5 are also symmetrically fixedly connected to the bottom of the inner cavity of the carton body 1, and the sliding rods 5 and the two sets of sliding plates 4 are slidably connected simultaneously. Springs 6 are sleeved on both sides of the sliding rods 5. Connecting rods 7 are symmetrically hinged between the sliding plates 4 and the bottom placement plates 2 via hinges. A cover plate 8 is rotatably connected to one side of the carton body 1 via a pivot. The cover plate 8 is provided with… The box 1 has a locking mechanism for easy sealing. Two sets of handles 9 are symmetrically fixed to the box 1 for easy movement. A handle 10 is fixedly connected to the top of the upper placement plate 2 for easy lifting. Movable grooves are provided on both sides of the middle and lower placement plates 2. Movable support columns 11 are slidably connected inside the movable grooves. A limit plate 12 is fixedly connected to one end of the movable support column 11. Arc-shaped grooves 13 are provided on both sides of the top of the box 1. Adjacent sets of placement plates 2 are fixedly connected by connecting columns 14.
[0024] The implementation principle of a multi-layer egg carton in this application embodiment is as follows: When storing, firstly, the movable support column 11 on the lower placement plate 2 is pulled out from the movable groove and placed in the arc-shaped groove 13. Then, eggs are placed in the placement groove 3 on the lower placement plate 2 in sequence. Subsequently, the movable support column 11 is pushed back into the movable groove and the placement plate 2 is slowly released by the handle 10. At this time, due to the increased weight of the placement plate 2, the sliding cooperation between the slide rod 5 and the slide plate 4, the rebound effect of the spring 6 itself, and the hinged cooperation between the slide plate 4 and the lowest placement plate 2 and the connecting rod 7, the lower placement plate 2 can automatically descend into the box body 1. Then, the above operation is repeated to place eggs on the middle placement plate 2, and finally, eggs are placed on the upper placement plate 2 to complete the storage of eggs. When all three sets of placement plates 2 are filled with eggs, the three sets of placement plates 2 are completely inserted into the box body 1. The lid 8 is closed and locked by the latch, making it easy to seal the box body 1.
[0025] When using the eggs, simply open the cover plate 8 and take the eggs directly from the upper placement plate 2. As eggs are continuously removed, the overall weight of the placement plate 2 decreases. Through the sliding cooperation between the slide rod 5 and the slide plate 4, the rebound effect of the spring 6, and the hinged action between the slide plate 4, the lower placement plate 2, and the connecting rod 7, the lower placement plate 2 can be pushed upwards. When all the eggs on the upper placement plate 2 have been removed, the middle placement plate 2 will move back to the initial position of the upper placement plate 2. Similarly, when all the eggs on the middle placement plate 2 have been removed, the lower placement plate 2 will move back to the initial position of the upper placement plate 2. This pushes the eggs on the lower placement plate 2 to a more accessible position, making it easier to use the eggs directly without any extra steps, thus increasing the convenience of the device.
[0026] Example 2:
[0027] This embodiment is an improvement on embodiment 1, wherein the two ends of the spring 6 are fixedly connected to the inner wall of the box 1 and the slide plate 4, respectively.
[0028] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
