Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter doors, in particular to a pry-proof bank anti-theft rolling shutter door structure. Background Art

[0002] Rolling door is a door that is connected in series with multiple joints, and rotates up and down in a fixed slideway with the roller above the door as the center. It consists of curtain plate, seat plate, guide rail, support, roller, box, control box, rolling door machine, limiter, door lintel, manual quick release switch device, button switch and safety device.

[0003] As an important financial institution, the bank carries a large amount of wealth and therefore faces a high security risk. In order to protect the safety of the bank and the interests of customers, the bank adopts a series of security measures including rolling shutters. In the prior art, except for the manual rolling shutters which are provided with a latch lock at the bottom when closed, most electric rolling shutters do not have a safety anti-theft mechanism after closing. As long as the lifting force is greater than the weight of the door body, the curtain piece will move up and the door leaf can be opened, which cannot play a role in safety protection and is not practical enough. Therefore, it is necessary to redesign a pry-proof bank anti-theft rolling shutter door structure to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a pry-proof bank anti-theft rolling shutter door structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] Advantages of the present utility model:

[0013] 1. By providing components such as a screw rod, a moving plate, a plug rod and a fixed block, when the screw rod rotates, it can drive the moving plate to move through cooperation with the limiting rod. During the movement of the moving plate, the plug rod can be driven to move into the jack on the outer wall of the fixed block.

By providing an upper ejector rod, an upper top block and a contact switch, when the curtain board is pried, through the transmission of force, the fixed block can drive the upper top block to move upward through the upper ejector rod, and thus the upper top block can be disengaged from the bottom wall of the contact switch. At this time, the contact switch is stressed and will supply power to the sound and light alarm, causing the sound and light alarm to flash and emit an alarm to achieve a warning effect.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Referring to Figures 1-6 , a structure of an anti-pry bank anti-theft rolling shutter door includes a guide rail 1 and a curtain board 2. Two upper ejector rods 4 are slidably installed on the inner wall of the guide rail 1 through a support mechanism. The support mechanism includes a support plate 3 fixedly installed on the inner wall of the guide rail 1. The upper ejector rod 4 slidably penetrates through the support plate 3. Upper ejector blocks 5 are fixedly installed on the outer walls of the two upper ejector rods 4. Return springs 6 are installed on the outer walls of the two upper ejector rods 4. Two ends of the two return springs 6 are elastically connected to the upper end surface of the support plate 3 on the same side and the bottom wall of the upper ejector block 5 respectively. Fixed blocks 7 are fixedly installed at the ends of the two upper ejector rods 4. Fixing holes are opened on the outer walls of the two fixed blocks 7. Two contact switches 8 cooperating with the upper ejector blocks 5 are fixedly installed on the inner wall of the guide rail 1. Two moving frames 9 are fixedly installed on the inner wall of the curtain board 2. Screw rods 10 are rotatably installed inside the two moving frames 9. Driven bevel gears 11 are fixedly installed on the outer walls of the two screw rods 10. A motor 13 is fixedly installed on the inner wall of the curtain board 2 through a connecting mechanism. The connecting mechanism includes a connecting frame 12 fixedly installed on the inner wall of the curtain board 2. The motor 13 is fixedly installed on the outer wall of the connecting frame 12.

[0024] The outer wall of the output shaft of the motor 13 is connected to the two driven bevel gears 11 through a rotating mechanism. The rotating mechanism includes a driving bevel gear 14 fixedly mounted on the outer wall of the output shaft of the motor 13. The driving bevel gear 14 is vertically meshed with the two driven bevel gears 11. The outer walls of the two screws 10 are both threadedly mounted with a moving plate 16. The two moving frames 9 are both fixedly mounted with a limit rod 15. The two limit rods 15 slide through the moving plates 16 on the same side respectively. The limit rod 15 can limit the moving plates 16 so that the moving plates 16 can only move axially along the outer wall of the screw 10. The outer walls of the two moving frames 9 are both slidably penetrated with a plug rod 17. The ends of the two plug rods 17 are respectively fixedly connected to the outer walls of the moving plates 16 on the same side. The outer wall of the guide rail 1 is fixedly mounted with two sound and light alarms 19 through a connecting mechanism. The connecting mechanism includes a connecting plate 18 fixedly mounted on the outer wall of the guide rail 1, and the sound and light alarm 19 is fixedly mounted on the upper end surface of the connecting plate 18.

[0025] When the utility model is used, when the rolling shutter door is in a closed state, the motor 13 can drive the active bevel gear 14 to rotate, and at this time the active bevel gear 14 can engage and rotate the two driven bevel gears 11 and make the two screws 10 rotate. When the screw 10 rotates, it can drive the moving plate 16 to move by cooperating with the limiting rod 15. During the movement of the moving plate 16, the plug rod 17 can be driven to move to the insertion hole of the outer wall of the fixed block 7. Through the cooperation of the plug rods 17 on both sides and the insertion hole, the limit between the curtain plate 2 and the guide rail 1 can be achieved to prevent the curtain plate 2 from being pried open;

[0026] When the curtain plate 2 is pried, the force on it can drive the fixing block 7 to move upward through the insertion rod 17. At this time, the distance between the curtain plate 2 and the ground is extremely small, which does not affect the protective effect of the rolling shutter door. At the same time, the fixing block 7 can drive the upper ejector block 5 to move upward through the upper ejector rod 4 and squeeze the reset spring 6, thereby making the upper ejector block 5 contact the bottom wall of the contact switch 8. At this time, the contact switch 8 will be powered by the sound and light alarm 19 when it is subjected to force, so that the sound and light alarm 19 flashes and sounds an alarm. When the curtain plate 2 is not forced to move downward and reset, the upper ejector block 5 can be driven to move downward and reset under the elastic action of the reset spring 6, thereby making the contact switch 8 free from force, thereby disconnecting the power supply to the sound and light alarm 19 and releasing the alarm state of the sound and light alarm 19. Before the rolling shutter door is opened, the motor 13 can drive the active bevel gear 14 to reverse. At this time, the insertion rod 17 can be moved out of the insertion hole under the reverse drive of the screw rod 10, thereby releasing the limit between the curtain plate 2 and the guide rail 1.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
