Description

Technical Field

[0001] This utility model relates to the field of linkage door technology, and in particular to a linkage door with anti-collision buffer. Background Technology

[0002] Interlocking doors refer to two doors that are mutually locked. When one door is opened, the other cannot be opened; either door can only be opened when both are closed. According to bank security regulations, two doors must be installed at the entrances and exits of cash counters in savings branches and other financial institutions. Employees must lock the first door (outer door) properly before entering the second door (inner door). If the first door is not properly closed, the employee will not be allowed to enter the second door. This effectively prevents unauthorized personnel from entering the bank or other financial institutions.

[0003] However, the above-mentioned operating procedures are completed manually, and errors are inevitable when done manually. If the operator is distracted, the first door (outer door) may not be closed or properly closed, which could lead to serious information leaks within the financial sector. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-8 This utility model provides a technical solution for a linkage door with anti-collision buffer: A linkage door with anti-collision buffer includes a passage 1, a first door panel 2 on the right side of the passage 1, and a second door panel 4 on the left side of the passage 1. Two hinges are provided on the rear side of the first door panel 2 and the front side of the second door panel 4. The first door panel 2 and the second door panel 4 are movably connected to the passage 1 through the hinges. A first door lock 3 is installed on both the left and right sides of the first door panel 2, and a second door lock 5 is installed on both the left and right sides of the second door panel 4. The first door lock 3 is close to the front side of the first door panel 2, and the second door lock 5 is close to the rear side of the second door panel 4. A protective cover 6 is matched with the first door lock 3 and the second door lock 5 respectively.

[0027] Protective covers 6 are provided on the left side of the first door panel 2 and the right side of the second door panel 4. A movable rod 7 is fixedly connected to the top of the protective cover 6. Two through holes are opened at the top of the channel 1. The top of the movable rod 7 moves through the adjacent through holes. The cross-section of the movable rod 7 is L-shaped. A first slot 8 is opened on the movable rod 7. A fixed rod 9 moves through the inner cavity of the first slot 8. A connecting plate 10 is fixedly connected to the bottom of the fixed rod 9. A connecting rod 11 is fixedly connected to the side wall of the connecting plate 10. Two second slots 19 are opened at the top of the channel 1. The connecting rod 11 is inclined. The bottom of the connecting rod 11 moves through the second slot 19. A rotating shaft 12 is fixedly connected through the connecting rod 11. The rotating shaft 12 is rotatably connected to the inner cavity of the second slot 19.

[0028] A mounting bracket 13 is provided on one side of the connecting rod 11. A roller 14 is rotatably connected to the inner side of the mounting bracket 13. The connecting rod 11 and the roller 14 are in contact with each other. A fixing plate 16 is provided on the side of the mounting bracket 13 away from the connecting rod 11. A spring 17 is provided on the side of the fixing plate 16 away from the mounting bracket 13. A crossbar 15 is movably passed through the fixing plate 16. One end of the crossbar 15 is fixedly connected to the mounting bracket 13. The other end of the crossbar 15 movably passes through the spring 17 and is fixedly connected to a pressure plate 18. The fixing plate 16 is fixedly connected to the top of the inner cavity of the channel 1. The two ends of the spring 17 are fixedly connected to the pressure plate 18 and the fixing plate 16 respectively. The two pressure plates 18 are in contact with the first door panel 2 and the second door panel 4 respectively. The spring 17 is in a compressed state.

[0029] Working principle: This utility model is a linkage door with anti-collision buffer. During use, the staff enters the passage 1 by opening the first door lock 3 on the right side of the first door panel 2. At this time, the first door panel 2 moves away from the adjacent pressure plate 18. The pressure plate 18 moves under the elastic action of the spring 17. The pressure plate 18 drives the crossbar 15 and the roller 14 to move away from the connecting rod 11. The connecting rod 11 is no longer limited by the roller 14. The movable rod 7 and the protective cover 6 move downward under the action of gravity. At the same time, the connecting rod 11 rotates around the pivot 12. The connecting rod 11 drives the fixed rod 9 to move in the inner cavity of the first slot 8. That is, the protective cover 6 on the right side of the second door panel 4 moves downward to block the second door lock 5.

[0030] Afterwards, the staff enters passage 1. At this time, because the first door panel 2 is opened, the protective cover 6 on the right side of the second door panel 4 moves downward and blocks the second door lock 5, making it impossible to operate the second door lock 5 on the right side of the second door panel 4. At this time, the first door panel 2 must be closed. When the first door panel 2 is closed, it pushes the adjacent pressure plate 18 to move inward to the inside of passage 1. At the same time, the spring 17 is compressed. The pressure plate 18 drives the crossbar 15 and the roller 14 to move in the direction of the connecting rod 11. The roller 14 pushes the connecting rod 11 to flip. The roller 14 rolls on the surface of the connecting rod 11. The connecting rod 11 flips around the pivot 12. The connecting rod 11 drives the fixed rod 9 to flip upward. The fixed rod 9 drives the movable rod 7 to move upward. The movable rod 7 drives the protective cover 6 to move upward. That is, the protective cover 6 on the right side of the second door panel 4 moves upward and exposes the second door lock 5. Only then can the second door lock 5 on the right side of the second door panel 4 be operated to open the second door panel 4.

[0031] After opening the second door panel 4 and entering the passage 1, the protective cover 6 on the left side of the first door panel 2 moves downward to cover the first door lock 3 on the left side of the first door panel 2. Only when the second door panel 4 is closed can the protective cover 6 on the left side of the first door panel 2 be moved upward to expose the first door lock 3 on the left side of the first door panel 2. Only then can the first door lock 3 on the left side of the first door panel 2 be operated to open the first door panel 2.

[0032] During the use of this device, after the staff enters the passage 1, they must close the open door panel in order for the corresponding protective cover 6 to move upward and expose the corresponding door lock. This achieves mechanical linkage and prevents the staff from being distracted and causing the door panel to not be closed or closed tightly, thereby preventing unauthorized personnel from following in and improving safety.

[0033] When the first door panel 2 and the second door panel 4 are closed, the first door panel 2 and the second door panel 4 first come into contact with the corresponding pressure plate 18, and the pressure plate 18 compresses the spring 17, thereby playing a role in anti-collision buffering.
