[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-7 As shown, a sealing structure for a sliding inspection door and an operating room includes an inspection door 1 and a door frame 2, including a convex strip 22 fixedly arranged on the edge of the door frame 2:

[0029] A rubber frame 11 fixedly mounted on the inspection door 1 includes a groove for accommodating the ridge 22;

[0030] The sealing strip 12 is located on the groove and is used to seal the gap between the convex strip 22 and the rubber frame 11. It is Z-shaped to fit the convex strip 22, and the sealing strip 12 expands and fills as the inspection door 1 and the door frame 2 are in close contact. A folding suction cup 15 is fixedly provided on the end face of the sealing strip 12, and the folding suction cup 15 folds when the sealing strip 12 expands.

[0031] Specifically, the ridge 22 includes at least one raised portion corresponding to the rubber frame 11. As the sliding access door 1 approaches the door frame 2 and the edges of the access door 1 and the door frame 2 cling to each other, the ridge 22 and the rubber frame 11 interlock and form a curved sealing path, which initially achieves a sealing effect. The sealing strip 12 then begins to expand and fill the gap between the ridge 22 and the rubber frame 11, achieving a better sealing effect.

[0032] Furthermore, a sensor can be set between the inspection door 1 and the door frame 2, and an air pump for inflating the sealing strip 12 can be installed on the inspection door 1, so that the sealing strip 12 expands when the inspection door 1 and the door frame 2 are in close contact; or an air bag connected to the sealing strip 12 can be set on the edge of the inspection door 1, and as the convex strip 22 squeezes the air bag, the gas is squeezed into the sealing strip 12 to expand; or other driving methods known to those skilled in the art can be used to achieve it.

[0033] Furthermore, when the sealing strip 12 expands, it drives the folding suction cup 15 toward the door frame 2, and the folding suction cup 15 is folded by the reaction force of the door frame 2, thereby being adsorbed on the door frame 2. The adsorption force of the folding suction cup 15 makes the sealing strip 12 fit better with the convex strip 22, thereby preventing the sealing strip 12 from being detached when the inspection door 1 shakes.

[0034] In the above technology, the sealing strip 12 expands and fills the gap between the convex strip 22 and the rubber frame 11, thereby achieving a better sealing effect. In addition, the adsorption force of the folding suction cup 15 makes the sealing strip 12 fit better with the convex strip 22, thereby preventing the sealing strip 12 from being detached when the inspection door 1 shakes.

[0035] As an embodiment further provided by the present invention, a sliding wheel 16 is slidably provided on the inspection door 1 , and a first spring 17 is provided on the sliding wheel 16 .

[0036] Specifically, the inspection door 1 makes sliding smoother through the setting of the sliding wheel 16, reducing the friction generated during the sliding process. The first spring 17 keeps the sliding wheel 16 in close contact with the ground, and can play a role in buffering vibrations, making the sliding of the inspection door 1 more stable.

[0037] As another embodiment further provided by the present invention, it also includes an air chamber 19 for inflating the sealing strip 12 and a piston plate 18 that cooperates with the piston of the air chamber 19. The piston plate 18 is fixedly connected to the sliding wheel 16, and a guide block 21 that slides with the sliding wheel 16 is provided on the door frame 2.

[0038] Specifically, during the process of the inspection door 1 approaching the door frame 2, the sliding wheel 16 contacts the guide block 21 and slides along the upper surface of the guide block 21, thereby causing the sliding wheel 16 to move up in the vertical direction. At this time, the first spring 17 contracts and drives the piston plate 18 to move up and squeeze the gas in the air chamber 19. The gas in the air chamber 19 enters the sealing strip 12, causing the sealing strip 12 to expand. When the inspection door 1 is closed, the sealing strip 12 automatically expands and blocks the gap between the inspection door 1 and the door frame 2. After the inspection door 1 is opened, the sliding wheel 16 slides in the opposite direction along the upper surface of the guide block 21, and the first spring 17 is released, driving the sliding wheel 16 to move down and driving the piston plate 18 to move down, sucking the air in the air chamber 19, so that the sealing strip 12 no longer expands and the sealing state is released.

[0039] As another embodiment further provided by the present invention, it also includes a locking clip 14 rotatably arranged on the rubber frame 11, a steel ball 23 is movably arranged on the door frame 2, and there is a station where the locking clip 14 is engaged with the steel ball 23 during the rotation process.

[0040] Specifically, a hook-shaped groove 141 with the same diameter as the steel ball 23 is provided on the locking clip 14, and a second spring 24 for pushing the steel ball 23 is provided in the door frame 2. When the inspection door 1 approaches the door frame 2, the locking clip 14 is tangent to the door frame 2 and rotates under the drive of friction. During the rotation of the locking clip 14, the steel ball 23 is first pushed upward, and the second spring 24 contracts. When the locking clip 14 rotates to the lower position, the hook-shaped groove 141 corresponds to the steel ball 23, and the steel ball 23 is pushed into the hook-shaped groove 141 under the elastic release of the second spring 24. At this time, the hook-shaped groove 141 is engaged with the steel ball 23, so that the inspection door 1 is automatically locked after closing.

[0041] As another embodiment further provided by the present invention, the locking clip 14 includes a trigger rod, and the locking clip 14 is provided with a torsion spring 142 for keeping the trigger rod at a predetermined angle.

[0042] Specifically, the trigger rod extends toward the door frame 2 at a predetermined angle. When the inspection door 1 approaches the door frame 2, the door frame 2 pushes the trigger rod to overcome the elastic force of the torsion spring 142 and rotates to the working position, thereby driving the hook groove 141 to engage with the steel ball 23.

[0043] As another embodiment further provided by the present invention, it also includes a vent pipe 13 arranged on the rubber frame 11, on which a connecting pipe 133 for connecting with the sealing strip 12 is fixedly arranged, and a rotating part 134 for sealing the connecting pipe 133 is arranged in the connecting pipe 133.

[0044] Specifically, the rotating member 134 is rotatably disposed within the connecting tube 133. The end of the rotating member 134 extends to the outside of the inspection door 1 and is provided with a torsion bar for manual rotation. The connecting tube 133 is provided with an opening at a location within the sealing strip 12, and the rotating member 134 is provided with a through-hole corresponding to the opening. To release the seal of the inspection door 1, the through-hole of the rotating member 134 is first rotated so that it corresponds to the opening. At this time, the sealing strip 12, the connecting tube 133, and the vent tube 13 are all connected, and the gas within the sealing strip 12 flows outward through the vent tube 13, and the inspection door 1 is no longer sealed. When the inspection door 1 remains sealed, the through-hole of the rotating member 134 is offset from the opening, the connecting tube 133 is blocked by the rotating member 134, and the sealing strip 12 remains inflated.

[0045] As another embodiment further provided by the present invention, an elastic folding bag 131 for pushing the steel ball 23 is provided at the end of the vent pipe 13 .

[0046] Specifically, an air outlet 132 is provided on the folding surface of the elastic folding bag 131, and the air outlets 132 of the elastic folding bag 131 are in contact with each other in the folded state. When the sealing state of the inspection door 1 needs to be released, the through hole of the rotating part 134 is first rotated to correspond to the opening. At this time, the sealing strip 12 and the connecting pipe 133 and the vent pipe 13 are all connected. The gas in the sealing strip 12 flows into the elastic folding bag 131 through the vent pipe 13, and the elastic folding bag 131 is expanded by the air pressure. Since the elastic folding bag 131 is provided on the rubber frame 11 and the elastic folding bag 131 is located directly below the locking clamp 14 station, the elastic folding bag 131 expands and pushes the steel ball 23 out of the hook-shaped groove 141, and the inspection door 1 is unlocked. After the elastic folding bag 131 is expanded, the air outlet 132 that was originally in contact expands, so that the air flows out through the air outlet 132, and the sealing strip 12 no longer expands. Then the sliding wheel 16 slides in the opposite direction along the upper surface of the guide block 21, and the first spring 17 is released, driving the sliding wheel 16 to move downward and driving the piston plate 18 to move downward, sucking the air in the air chamber 19, and then the through hole and the opening of the rotating part 134 are staggered, and the connecting pipe 133 is blocked by the rotating part 134.

[0047] Working Principle: As access door 1 approaches doorframe 2, sliding wheel 16 contacts guide block 21 and slides along its upper surface, causing sliding wheel 16 to move vertically. At this point, first spring 17 contracts, driving piston plate 18 upward and squeezing the gas within gas reservoir 19. The gas within gas reservoir 19 enters sealing strip 12, causing it to expand. When access door 1 is closed, sealing strip 12 automatically expands and blocks the gap between access door 1 and doorframe 2. Doorframe 2 pushes against the trigger lever, overcoming the elastic force of torsion spring 142 and rotating it to the working position, thereby engaging hook groove 141 with steel ball 23. To release the seal of access door 1, first rotate the through-hole of rotating member 134 to align with the opening. This now connects sealing strip 12 to connecting pipe 133 and vent pipe 13. Gas within sealing strip 12 flows through vent pipe 13 into elastic accordion bladder 131, which expands under the pressure. Since the elastic folding capsule 131 is provided on the rubber frame 11 and is located directly below the station of the locking clamp 14, the elastic folding capsule 131 unfolds and pushes the steel ball 23 out of the hook-shaped groove 141, and the inspection door 1 is unlocked. After the elastic folding capsule 131 unfolds, the air outlet 132 that was originally in contact with the rubber frame 11 unfolds, allowing the air to flow out through the air outlet 132, and the sealing strip 12 no longer expands. The sliding wheel 16 then slides in the opposite direction along the upper surface of the guide block 21, and the first spring 17 is released, driving the sliding wheel 16 and the piston plate 18 downward, sucking the air in the air chamber 19, and then the through hole of the rotating member 134 is staggered with the opening, and the connecting pipe 133 is blocked by the rotating member 134.

[0048] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
