[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides an L-shaped path isolation door, including a support base 1, an isolation door 2, and a drive structure. There are two support bases 1, each with two L-shaped tracks 3 on its adjacent side. The L-shaped tracks 3 are L-shaped and arranged in parallel. Two rotating shafts 4 are connected to the isolation door 2, one of which penetrates through the door. A protruding strip protrudes from the surface of the isolation door 2 and is connected to one side of the door. The rotating shaft 4 rotates through the end of the protruding strip. The ends of the two rotating shafts 4 are respectively located within the two L-shaped tracks 3. The drive structure drives the rotating shaft 4 to slide within the L-shaped tracks 3.

[0027] It should be noted that the two rotating shafts 4 on the isolation door 2 are on the same horizontal plane on the isolation door 2, and the largest side of the isolation door 2 is the reference plane. The two rotating shafts 4 slide simultaneously into the bending sections of the two L-shaped tracks 3.

[0028] The drive structure includes a lead screw 5, a connecting plate 6, a push plate 7, and a connecting rotating assembly. One end of the lead screw 5 is connected to the connecting plate 6, which is mounted on the push plate 7. Two rotating shafts 8 are fixedly connected to both sides of the push plate 7, arranged symmetrically about the push plate 7. A connecting strip protruding from the surface of the push plate 7 is connected to the side of the push plate 7 closest to the isolation door 2, with rotating shafts 8 symmetrically connected to both ends of the connecting strip. The protruding strip is located on the isolation door 2 near the push plate 7, and it is diagonally opposite to the connecting strip. The two rotating shafts 8 are slidably mounted within two L-shaped tracks 3. Two connecting rotating assemblies are connected between the rotating shafts 8 and the rotating shaft 4.

[0029] The connecting rotating assembly includes a first chain link 9, a connecting rod 10, and a second chain link 11. One end of the first chain link 9 is fixedly mounted on the rotating shaft 8, and the other end of the first chain link 9 is rotatably connected to one end of the second chain link 11 through the connecting rod 10. The other end of the second chain link 11 is fixedly connected to the rotating shaft 4.

[0030] During use, the lead screw 5 is driven to move using existing technologies such as cylinders and hydraulic rods. The lead screw 5 pushes the connecting plate 6 and the push plate 7 to move synchronously. When the push plate 7 moves laterally, it drives the rotating shafts 8 on both sides to slide within the two L-shaped tracks 3. Since the rotating shafts 8 are connected to the first chain link 9, the movement of the rotating shafts 8 will drive the first chain link 9 to move. The first chain link 9 is rotatably connected to the second chain link 11 through the connecting rod 10, and the second chain link 11 is fixedly connected to the rotating shaft 4. When the first chain link 9 moves, it drives the two rotating shafts 3 to move. The rotating shaft 4 slides within the two L-shaped tracks 3, and simultaneously drives the isolation door 2 to slide laterally. At this time, the isolation door 2 moves horizontally. When the rotating shaft 4 moves to the bend section of the L-shaped track 3, the isolation door 2 moves synchronously with the rotating shaft 4 because the rotating shaft 4 enters the bend section at the same time. This increases the distance between the isolation door 2 and the push plate 7, causing the isolation door 2 to abut against the door frame and press against the sealing strip on the door frame, thus forming a sealing structure between the isolation door 2 and the door frame.

[0031] A sealing ring 12 is installed on the side of the isolation door 2. The sealing ring 12 has a ring-shaped structure. A storage groove for storing the sealing ring 12 is opened on the side of the isolation door 2. The storage groove is a rectangular groove that can fit perfectly against the side of the door frame. A rotating shaft 4 passes through the isolation door 2 and is rotatably connected to the isolation door 2. An eccentric protrusion 14 is connected to the outer periphery of the rotating shaft 4. A rotating groove is opened inside the isolation door 2 to rotatably engage with the eccentric protrusion 14. An ejector is slidably installed in the storage groove and is connected between the eccentric protrusion 14 and the sealing ring 12.

[0032] The ejector assembly includes a rectangular pusher 13 and a retraction component. The rectangular pusher 13 consists of a rectangular ring-shaped frame with vertical plates connected to both sides. A roller is rotatably connected to the side of the vertical plate away from the rectangular frame. The rectangular pusher 13 is slidably installed in the receiving groove. The outer side of the eccentric protrusion 14 is slidably engaged with one side of the rectangular pusher 13. A sealing ring 12 is installed on the side of the rectangular pusher 13 away from the eccentric protrusion 14. The retraction component allows the eccentric protrusion 14 to tend to retract into the receiving groove.

[0033] When the gap between the isolation door 2 and the push plate 7 changes, the isolation door 2 and the push plate 7 can be regarded as two parallel planes. Since the position between the connecting rod 10 and the push plate 7 does not change, the second link 11 is rotatably connected between the connecting rod 10 and the rotating shaft 4. It can be assumed that the rotating shaft 4 and the connecting rod 10 are two rotation points. The second link 11 can be regarded as a line segment connecting the two points of the rotating shaft 4 and the connecting rod 10. When the gap between the isolation door 2 and the push plate 7 increases, the line segment formed by the second link 11 needs to rotate to ensure that the gap between the two points of the rotating shaft 4 and the rotating shaft 8 changes, so as to ensure that the distance between the two rotation points remains unchanged. It is similar to a parallelogram. When the distance between two parallel sides increases, the angle between that side and its adjacent side will change.

[0034] Similarly, the angle between the second link 11 and the isolation door 2 will inevitably increase. Since the second link 11 is fixedly connected to the rotating shaft 4, a deflection occurs between the second link 11 and the isolation door 2. The rotating shaft 4 drives the eccentric protrusion 14 to rotate. When the eccentric protrusion 14 rotates, its outer surface contacts the upper roller of the first rectangular pusher 13. The first rectangular pusher 13 slides within the receiving groove due to the eccentric protrusion 14, and the first rectangular pusher 13 drives the sealing ring 12, which is adhered to it, to extend out of the receiving groove and abut against the door frame to form a sealing structure. With this design, when the isolation door 2 moves laterally, there will be no contact or friction between the isolation door 2 and the sealing ring 12, reducing the possibility of jamming when the isolation door 2 slides. Traditional sealing rings 12 are usually installed on the outside of the door frame or door panel. When waiting, some people will unconsciously reach out and pry them off. However, in this solution, the sealing ring 12 is hidden in the storage groove when the door is open or closed, and fingers cannot be inserted into the storage groove to pry it off.

[0035] The retraction assembly includes an anti-detachment slider 15 and a return spring 16. The anti-detachment slider 15 is connected to the side of the first rectangular pusher 13. The side wall of the storage slot is provided with a limiting groove that slides with the anti-detachment slider 15. The return spring 16 is located in the limiting groove, and the two ends of the return spring 16 are respectively connected to the inner wall of the limiting groove and the anti-detachment slider 15.

[0036] When the door is opened, the reset spring 16 acts on the anti-detachment slider 15, causing the anti-detachment slider 15 to slide within the limiting groove. The anti-detachment slider 15 then drives the first rectangular pusher 13 and the sealing ring 12 to retract into the storage groove for storage.

[0037] Example 2

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, the difference between this embodiment and embodiment one is that the sealing ring 12 is a hollow structure, and the installation position of the sealing ring 12 is also at the opening of the storage groove; moreover, the second rectangular pusher 17 does not need to retract the assembly when it retracts into the storage groove.

[0039] The ejector includes a second rectangular pusher 17; the structure of the second rectangular pusher 17 is the same as that of the first rectangular pusher 13. The sealing ring 12 is a hollow structure and is filled with liquid. The sealing ring 12 is installed at the opening of the receiving groove, and both sides of the sealing ring 12 are partially bonded to the inner wall of the receiving groove. The second rectangular pusher 17 is slidably installed in the receiving groove, and the width of the second rectangular pusher 17 is the same as the width of the receiving groove. The two ends of the second rectangular pusher 17 abut against the sealing ring 12 and the eccentric protrusion 14, respectively.

[0040] When the second rectangular pusher 17 pushes the sealing ring 12, the sealing ring 12 is compressed. Since only part of both sides of the sealing ring 12 are bonded to the inner wall of the opening of the storage groove, the partial bonding design between the sealing ring 12 and the inner wall of the opening of the storage groove allows the sealing ring 12 to have a greater amount of compression, causing the liquid inside the sealing ring 12 to exert greater pressure on the sealing ring 12 on the outer side of the storage groove. The liquid inside the sealing ring 12 expands outward under compression, causing the outwardly expanding sealing ring 12 to press against the door frame to complete the seal.

[0041] During retraction, the deformation of the sealing ring 12 itself causes the second rectangular pusher 17 to retract into the storage groove.

[0042] Example 3

[0043] Please see Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 As shown. The difference between this embodiment and Embodiments 1 and 2 is that the two sides of the sealing ring 12 are completely bonded to the inner walls of the two sides of the opening of the storage groove. When the sealing ring 12 is pushed out of the storage groove, the rectangular frame 19 is used to push the sealing ring 12 to deform and protrude out of the storage groove to abut against the door frame for sealing.

[0044] The ejector assembly includes a third rectangular pusher 18 and a rectangular frame 19; the third rectangular pusher 18 and the first rectangular pusher 13 have the same structure. The third rectangular pusher 18 is slidably installed in the storage slot, and one end of the third rectangular pusher 18 is slidably engaged with the outer wall of the eccentric protrusion 14. The rectangular frame 19 is connected to the side of the third rectangular pusher 18 away from the eccentric protrusion 14, and the side of the rectangular frame 19 away from the third rectangular pusher 18 abuts against the sealing ring 12. The width of the rectangular frame 19 is smaller than the width of the sealing ring 12.

[0045] In actual use, the third rectangular pusher 18 pushes the rectangular frame 19 to move within the storage groove. The rectangular frame 19 compresses the sealing ring 12, causing the middle part of the sealing ring 12 to deform and protrude outward from the storage groove, abutting against the door frame to complete the seal. The width of one side of the rectangular frame 19 is smaller than the width of the storage groove, which facilitates the deformation of the sealing ring 12 to protrude outward from the storage groove. The repositioning of the rectangular frame 19 and the third rectangular pusher 18 is driven by the deformation of the sealing ring 12 to retract into the storage groove.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
