[0026] Referring to Figures 1-5, a leak-proof food packaging box with a self-locking sealing lid includes a box body 1 and a lid 2. The bottom of the lid 2 has a first slot 201, and the inner wall of the first slot 201 is provided with a rubber pad 3, which is inserted and connected to the top of the box body 1. The top of the box body 1 has a fixing plate 4 on both sides, and the fixing plate 4 is inserted and connected to a second slot 202 on the top of the first slot 201. A second sliding groove 203 is provided on one side of the second slot 202, and a wedge block 5 is slidably installed in the second sliding groove 203. The wedge block 5 matches the limiting groove 401 on the fixing plate 4, and a connecting post 6 is fixedly installed at one end. The end of the connecting post 6 extends to the outside of the box body 1 and is fixedly installed with a first handle 7. A spring 8 is sleeved on the connecting post 6, and the two ends of the spring 8 are respectively connected to the first handle 7 and the outer wall of the box body 1.
[0027] In this embodiment, after the lid 2 is placed on top of the box body 1 and pressed, the box body 1 will be inserted into the first slot 201, and the sealing effect can be ensured by the rubber gasket 3. During the insertion process, the fixing plate 4 will enter the second slot 202 and push the wedge block 5 away from the limiting groove 401 in the second slide groove 203. At this time, the spring 8 is in a stretched state. When the limiting groove 401 is aligned with the second slide groove 203, the elastic force of the spring 8 will push the wedge block 5 into the limiting groove 401, which can lock the fixing plate 4 in the second slot 202, realizing the self-locking of the lid 2. It is more convenient to use without manual operation. Similarly, after pulling the first handle 7 outward, the wedge block 5 can be driven away from the limiting groove 401, which can release the locking of the fixing plate 4 in the second slot 202. At this time, the lid 2 can be removed from the top of the box body 1.
[0028] Guide rails 9 are fixedly installed on both sides of the box body 1. Pins 10 are slidably installed on the guide rails 9. The pins 10 are located on the movement trajectory of the first handle 7 and match the pin holes 701 opened on the first handle 7.
[0029] In the above embodiment, after pulling the first handle 7 to drive the wedge block 5 away from the limiting groove 401, the pin 10 can be installed on the guide slide 9 and the pin 10 can be inserted into the pin hole 701, thereby locking the wedge block 5 in the current position. At this time, the box cover 2 can be directly removed from the top of the box body 1.
[0030] It also includes multiple layered boxes 11, which are stacked inside the box body 1 to hold different types or flavors of food.
[0031] The inner wall of the box 1 is provided with a first sliding groove 101 on both sides. The bottom of the first sliding groove 101 coincides with the top of the uppermost layered box 11. A pressure plate 12 is slidably installed in the first sliding groove 101. One end of the pressure plate 12 is threadedly connected to a threaded rod 13. The threaded rod 13 is rotatably connected to the box 1, and its end extends to the outside of the box 1 and is provided with a second handle 14.
[0032] In this embodiment, after grasping the second handle 14 and rotating it, the threaded rod 13 rotates synchronously, which drives the pressure plate 12 to slide in the first slide groove 101 so that the pressure plate 12 abuts against the top of the uppermost layered box 11, thereby preventing the layered box 11 from shaking inside the box body 1 during transportation.
[0033] The bottom of the box body 1 is provided with a rectangular array of card blocks 15, which match the card slots 204 opened on the top of the box cover 2.
[0034] In this embodiment, during stacking and transportation, the upper card block 15 can be engaged in the lower card slot 204 to improve the stability during stacking and prevent collapse during transportation.
[0035] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
[0036] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
