Technical Field

[0001] This utility model relates to the field of vacuum lunch box technology, and more specifically, to a square-structured vacuum lunch box with a leak-proof mechanism. Background Technology

[0002] A vacuum lunch box is a type of lunch box that uses vacuum technology. Its main feature is its ability to effectively isolate heat transfer, thus providing a long-lasting heat preservation effect. The body of a vacuum lunch box is designed with a vacuum, with vacuum between the layers. This effectively isolates heat conduction, achieving a better heat preservation effect.

[0003] Currently, some vacuum lunch boxes use buckles to connect and fix the lid to the body. However, these buckles need to be operated independently, which is inconvenient and can easily lead to accidental loosening and leakage. Therefore, we provide a square vacuum lunch box with a leak-proof mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a square-structured vacuum lunch box with a leak-proof mechanism to solve the problems mentioned in the background art.

[0005] Currently, some vacuum lunch boxes use clips to connect and secure the lid to the body. However, these clips require independent operation, which is inconvenient as users need to operate them multiple times during use. They are also prone to accidental loosening, leading to leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A square vacuum lunch box with a leak-proof mechanism includes a box body and a lid. The lid has a circular hole inside, and a circular plate is rotatably connected inside the circular hole. A first groove is formed inside the lid on the side near the circular hole, and a second groove is formed on the side of the lid away from the circular hole. Both the circular hole and the second groove communicate with the first groove. A locking block is slidably connected inside the second groove, and a sliding plate is slidably connected inside the first groove. The sliding plate is fixedly connected to the locking block. The box body has a locking groove inside, which cooperates with the locking block. An inclined groove is formed inside the circular plate and above the sliding plate. A sliding rod is slidably connected inside the inclined groove and fixedly connected to the sliding plate.

[0008] Preferably, the outer side of the card block near the slide plate is provided with a slope.

[0009] Preferably, a limiting groove is formed inside the box cover and on the corresponding two sides of the slide plate. The limiting groove communicates with the first groove. A limiting block is slidably connected inside the limiting groove, and the limiting block is fixedly connected to the slide plate.

[0010] Preferably, the circular plate has a third groove inside, and a slider is slidably connected inside the third groove. A spring is provided between the slider and the third groove. One end of the spring is fixedly connected to the circular plate, and the other end of the spring is fixedly connected to the slider. An insert is fixedly connected to the side of the slider away from the spring. The insert penetrates the circular plate and extends to the outside of the circular plate. The insert is slidably connected to the circular plate. The box cover has a slot inside, and the slot is used in conjunction with the insert.

[0011] Preferably, a handle is fixedly connected to the top of the slider, and the handle is slidably connected to the circular plate.

[0012] Preferably, the outer side of the insert block away from the slider has a chamfer.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By rotating the circular plate with the handle, the plate presses against the sliding rod through the inclined groove. The sliding rod, via the slide plate, moves the locking block closer to the slot and engages with it. Simultaneously, under the elastic force of the spring, the insert block engages with the slot. To open the box cover, push the handle. The handle, via the slider, moves the insert block away from the slot. Then, by rotating the circular plate with the handle, the locking block is separated from the slot. Simply rotating the circular plate controls the engagement and disengagement of the four locking blocks and slots. The operation is convenient, and the requirement to push the handle before rotating the circular plate prevents accidental contact and leakage. Attached Figure Description

A first groove 5 is formed on the side of the lid 2 closest to the hole 3, and a second groove 6 is formed on the side of the lid 2 furthest from the hole 3. Both the hole 3 and the second groove 6 communicate with the first groove 5. A locking block 7 is slidably connected inside the second groove 6. Four locking blocks 7 engage with locking slots 9 from four different directions. The mechanism can be easily changed by rotating the circular plate 4. The four locking blocks 7 are operated simultaneously. The first groove 5 has a sliding plate 8 slidably connected inside, and the sliding plate 8 is fixedly connected to the locking block 7. The box body 1 has a locking groove 9 inside, which is used in conjunction with the locking block 7. The circular plate 4 has an inclined groove 10 inside and above the sliding plate 8. The inclined groove 10 has a sliding rod 11 slidably connected inside, and the sliding rod 11 is fixedly connected to the sliding plate 8. When the circular plate 4 rotates, it will drive the sliding plate 8 to move through the inclined groove 10 and the sliding rod 11. The sliding plate 8 then controls the locking block 7 to engage or disengage from the locking groove 9.

[0024] Furthermore, a slope 20 is provided on the outer side of the card block 7 near the slide plate 8. After the card block 7 engages with the card slot 9, the pressure from the slope 20 can make the lid 2 and the box body 1 more secure.

[0029] The steps for using this utility model are as follows: When using this square vacuum lunch box with a leak-proof mechanism, place the lid 2 on the box body 1, rotate the circular plate 4 by the handle 19, the circular plate 4 presses the slide rod 11 through the inclined groove 10, the slide rod 11 drives the locking block 7 to approach the locking groove 9 through the slide plate 8 and engage with it. At the same time, under the elastic force of the spring 16, the insert 17 engages with the slot 18. To open the lid 2, push the handle 19, the handle 19 drives the insert 17 to separate from the slot 18 through the slider 15, and then rotate the circular plate 4 by the handle 19. The circular plate 4 again drives the slide plate 8 and locking block 7 to move through the inclined groove 10 and the slide rod 11. At this time, the locking block 7 separates from the locking groove 9. Only rotating the circular plate 4 is needed to control the engagement and disengagement of the four locking blocks 7 and the locking groove 9, making the operation more convenient. Moreover, the circular plate 4 needs to be pushed first before rotating the handle 19 to prevent accidental contact and prevent leakage.
