[0003] The utility model with application No. CN202323404921.8 (publication No. CN221564078U) discloses a plastic storage box with a slidable cover, which comprises a cover and a box body. Two limit grooves, which are closed at one end and open at the other end, are symmetrically arranged on the bottom of the cover along the length direction. The cross-sectional structure of the limit groove is inverted T-shaped. A limit protrusion, which is matched with the limit groove, is symmetrically arranged on the top of the side wall of the box body along the length direction. The cross-sectional structure of the limit protrusion is T-shaped.

[0004] The above-mentioned patent is a kind of existing box body with slidable cover. The opening and closing of the box body are realized by the cover that can be pulled out. However, the box body lacks sealing after being closed. The common cross-sectional shapes of the inflatable sealing ring include O-shaped and D-shaped. On the one hand, the sealing is not strict and leakage may occur after long-term use through surface sealing. On the other hand, the conventional sealing ring cannot completely retract into its installation groove after being inflated, which is not convenient for the installation and removal of the drawer type box cover.

[0033] like Figures 1-5 As shown, this utility model provides a sealing ring structure for a pull-out box, which has a box body 1, a box cover 13 slidably connected to the top of the box body 1, a sealing groove 15 opened on the top of the box body 1, and a sealing ring 2 that cooperates with the box cover 13 to seal the box body 1 installed in the sealing groove 15.

[0034] When the sealing ring 2 is inflated, it abuts against the bottom surface of the box cover 13 to form a linear seal. When the sealing ring 2 is not inflated, it is far away from the bottom surface of the box cover 13.

[0035] Optionally, in the above technical solution, the sealing groove 15 has a square ring structure, the sealing ring 2 has a hollow air cavity 20 inside, and the sealing ring 2 is composed of a U-shaped part 21, two adjusting parts 22 and a protrusion 23. The two sides of the protrusion 23 are respectively fixedly connected to the ends of the two adjusting parts 22 that are close to each other, and the ends of the two adjusting parts 22 that are far from each other are respectively fixedly installed on the same side of the upper end of the U-shaped part 21.

[0036] Optionally, in the above technical solution, the bottom wall of the U-shaped part 21 abuts against the bottom wall of the sealing groove 15, and the side wall of the U-shaped part 21 abuts against the side wall of the sealing groove 15.

[0037] Optionally, in the above technical solution, the middle of the left and right sides of the sealing groove 15 is provided with a slot 16 that penetrates the outer wall of the box 1, and an air inlet 31 is inserted into the slot 16.

[0038] Optionally, in the above technical solution, the front wall of the box 1 is provided with a through pull-out opening 11, and the inner rear wall and inner side wall of the box 1 are provided with pull-out grooves 12. The bottom walls of the pull-out opening 11 and the pull-out grooves 12 are located on the same plane, and the sealing groove 15 is opened on the bottom wall formed by the pull-out opening 11 and the pull-out grooves 12.

[0039] A lid 13 is slidably connected to both the pull-out opening 11 and the pull-out groove 12, and the front end of the lid 13 has a handle 14.

[0040] Optionally, in the above technical solution, the air inlet 31 is fixedly connected to the front and rear ends of the sealing ring 2 and communicates with the inside of the air inlet 20.

[0041] The direction of the pull-out is perpendicular to the line connecting the two air nozzles 31 to avoid interference.

[0042] Among them, the sealing ring 2 is a square ring structure that is adapted to the sealing groove 15.

[0043] Among them, the air inlet 31 is an existing structure, which has its own anti-leakage function.

[0044] like Figure 4 When the inflation chamber 20 is filled with gas, the top of the protrusion 23 abuts against the bottom wall of the cover 13, and the ends of the adjusting parts 22 that are close to each other tilt upwards; Figure 3 When the gas in the inflation chamber 20 is released, the top of the protrusion 23 is not higher than the top of the sealing groove 15, and the adjustment part 22 is in a horizontal state.

[0045] Working principle:

[0046] First, completely detach the lid 13 from the body 1, install the sealing ring 2 into the sealing groove 15, and snap the air inlet 31 into the slot 16 (at this time, the sealing ring 2 is lower than the height of the sealing groove 15).

[0047] During sealing: Insert the lid 13 into the pull-out slot 12 along the pull-out opening 11, inflate one of the air nozzles 31 (the other air nozzle 31 is closed), and the sealing ring 2 expands after inflation. The gas in the inflation chamber 20 drives the protrusion 23 to move vertically upward, and the two adjustment parts 22 tilt upward at the same time. After inflation is completed, the protrusion 23 adheres tightly to the bottom wall of the lid 13 to generate a sealing force, thereby sealing the box 1 (the seal here is a linear seal, that is, there is a sealing line between the protrusion 23 and the lid 13). This can meet the requirement of long-term sealing for 3 months.

[0048] When the box cover 13 needs to be pulled out: open the two air inlet valves 31, and make the gas in the sealing ring 2 quickly leak through the two air inlet valves 31 (the leakage time is less than 10s), at this time, the sealing ring 2 is contracted after being leaked, and returns to the state of being lower than the height of the sealing groove 15 (i.e. the convex part 23 does not abut against the box cover 13), so that the box cover 13 can be smoothly pulled out.

[0049] The preferred embodiments of the present application are described above, but the present application is not limited to the above. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
