Description

Technical Field

[0001] This utility model relates to the field of isolator rat hole door technology, specifically an automatic pull-up stopper door. Background Technology

[0002] Segmented sterilization of the isolator's interior is gradually becoming a widely recommended sterilization method. This requires the installation of a sealed rat-hole door between the front and rear cavities at the boundary of the isolator's zones. The isolator needs to maintain a relatively stable pressure gradient relative to the room, and the interior of the isolator must be sterilized before production, thus meeting certain leakage rate requirements. For isolators requiring zoned sterilization, a sealing structure for the rat-hole door is needed at the connection between the front and rear zones. At the same time, sterilization must be thorough, and the rat-hole door must be easy to operate and clean.

[0003] Existing mouse hole doors are divided into lift doors and plug doors. During sterilization, there are sterilization dead corners at the connection between the lift door and the airtight seal. After sterilization, when the door is opened, the sterilization dead corners will be directly exposed inside the cavity, which will lead to contamination of the cavity. In addition, both the existing plug doors and lift doors need to be opened manually, which is cumbersome and poses a risk of contamination during manual opening. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 An automatic pull-out stopper includes: a rat hole door 1 and two limiting rails 2 installed on the inner side of the isolator wall, with the two limiting rails 2 located on both sides of the rat hole door 1. A rodless cylinder 3 is installed inside each of the two limiting rails 2. A first movable arm and a second movable arm are respectively installed on the piston surface of the two rodless cylinders 3. One end of the first movable arm and the second movable arm are connected to the surface of the rat hole door 1. A guide groove 6 is provided on the surface of the limiting rail 2, and the surface of the second movable arm is connected to the inner wall of the guide groove 6.

[0019] The mouse hole door 1 is symmetrically provided with a first positioning ear 7 and a second positioning ear 8, and the first positioning ear 7 is rotatably connected to the first movable arm, and the second positioning ear 8 is rotatably connected to the second movable arm.

[0020] The first movable arm includes a transition rod 41 and a first connecting rod 42. The transition rod 41 is mounted on the piston surface of the rodless cylinder 3. One end of the transition rod 41 is rotatably connected to one end of the first connecting rod 42, and the other end of the first connecting rod 42 is rotatably connected to the first positioning ear 7.

[0021] The transition rod 41 includes a support section 411 and a fixing plate 412. The support section 411 and the fixing plate 412 are integrally formed and connected. The fixing plate 412 is installed on the piston surface of the rodless cylinder 3. One end of the support section 411 is rotatably connected to the top end of the first connecting rod 42.

[0022] The fixing plate 412 is provided with screws 9. The piston surface of the rodless cylinder 3 is provided with fixing holes corresponding to the position of screws 9, and the inner wall of the fixing holes is threaded to one end of screws 9.

[0023] The second movable arm includes a second connecting rod 51 and a limiting bearing 52. The top end of the second connecting rod 51 is rotatably connected to the piston surface of the rodless cylinder 3. The bottom end of the second connecting rod 51 is connected to a connecting post 10. The connecting post 10 is mounted on the second positioning ear 8, and the limiting bearing 52 is mounted on the surface of the connecting post 10. The surface of the limiting bearing 52 is slidably connected to the inner wall of the guide groove 6.

[0024] Connecting bearings 11 are installed at both ends of the first connecting rod 42 and at the top of the second connecting rod 51.

[0025] The guide groove 6 is an L-shaped guide groove 6.

[0026] When the mouse hole door 1 needs to be opened, the rodless cylinder 3 is activated. The piston of the rodless cylinder 3 drives the first and second movable arms to move. When the piston moves, it also drives the transition rod 41 and the connecting column to move. The top of the first connecting rod 42 rotates around one end of the support section 411 of the transition rod 41. The second connecting rod 51 is rotated and connected to the piston of the rodless cylinder 3 through the connecting column. When the first connecting rod 42 and the second connecting rod 51 are pulled, the limit bearing 52 slides in the guide groove 6, thereby guiding the movement trajectory of the mouse hole door 1, so that the mouse hole door 1 can move in the direction perpendicular to the movement direction of the rodless cylinder 3 and in the direction parallel to the movement direction of the rodless cylinder 3. This allows the mouse hole door 1 to smoothly enter and exit the mouse hole, which can reduce the sterilization dead angle between the mouse hole door 1 and the mouse hole, making sterilization more thorough and reducing the risk of contamination. The opening and closing of the mouse hole door 1 is driven by the rodless cylinder 3, reducing manual intervention.
