Description

Technical Field

[0001] The utility model relates to the technical field of rolling door equipment, in particular to a fast automatic rolling door. Background Art

[0002] Automatic rolling doors can be opened and closed quickly, greatly improving the traffic efficiency of people and vehicles, reducing waiting time, and thus improving operational efficiency. At the same time, its anti-pinch, anti-collision, anti-pry and other safety functions can effectively protect the safety of people and vehicles.

[0003] There are many existing technologies for automatic rolling doors, such as:

[0004] Chinese patent announcement number CN214118020U discloses an automatic rolling shutter door, which includes a bracket, a rolling door, and a reel. Two brackets are provided and the two brackets are vertically fixedly connected to the ground. The reel is provided at the top position between the two brackets, and the two ends of the reel are respectively rotatably connected to the two brackets. The rolling door is slidably connected between the two brackets. One end of the rolling door close to the reel is fixedly connected to the reel. One end of the bracket side wall close to the reel is provided with a roller brush assembly along the width direction of the rolling door. The roller brush assembly includes a roller brush, a first rotating shaft, and a first fixed plate. The first fixed plates are respectively vertically fixedly connected to the side walls of the two brackets. The two ends of the first rotating shaft are respectively rotatably connected to the two first fixed plates. The roller brush is sleeved on the first rotating shaft. The length of the roller brush is the same as the width of the rolling door. The side of the roller brush close to the rolling door is closely attached to the surface of the rolling door. The present application has the effect that the cleaning mechanism of the rolling shutter door itself can easily clean the entire surface of the rolling shutter door.

[0005] When the existing automatic silent rolling shutter door is closed, if the user does not notice the state of the rolling shutter door, the rolling shutter door will continue to fall even when it has reached the bottom, thereby causing damage to the rolling shutter door or even the driving structure. In addition, in order to raise the rolling shutter door that was originally in a closed state, the driving structure needs to be started again to roll up the rolling shutter door, which consumes more energy than the rolling shutter door lowering process. For example, the automatic rolling shutter door proposed in the above patent drives the rolling shutter door up and down through the roller, and cannot remind the operator when the rolling shutter door falls to the lowest point, and has the problem of high energy consumption when rolling up the rolling shutter door.

[0006] In view of this, we propose a fast automatic rolling door to improve the shortcomings of the existing technology. Utility Model Content

[0009] As a further improvement of the technical solution, the driving assembly includes a pair of door frames arranged at intervals, a main rod is rotatably connected between the tops of the two door frames, a reel is coaxially connected to the periphery of the main rod, and the main rod is driven by a servo motor.

[0026] Example

[0027] See also Figure 1-Figure 4 As shown, the present embodiment provides a fast automatic rolling door, including a driving assembly 10 installed in a wall, a rolling door 20 is wound on the top of the driving assembly 10, the driving assembly 10 is used to drive the rolling door 20 to rise and fall, a deceleration assembly 30 is coaxially connected to one side of the top of the rolling door 20, the deceleration assembly 30 is used to ensure the stability of the rolling door 20 when it descends, and an unlocking assembly 40 is provided on the top of the deceleration assembly 30, the unlocking assembly 40 is used to release the restriction of the deceleration assembly 30 on the driving assembly 10 during rotation.

[0028] Working principle: When the fast automatic rolling shutter door provided by the utility model is used, the driving component 10 is provided to drive the rolling door 20 to rise and fall, and then the rolling door 20 at the lowest point is automatically retracted through the torsion spring 50, and the deceleration component 30 is used to ensure the stability of the rolling door 20 when it descends. In addition, the "click" sound emitted by the deceleration claw 32 when it passes through the surface of the deceleration wheel 31 reminds the operator of the status of the rolling door 20 at all times, and then the unlocking component 40 is used to release the restriction of the deceleration component 30 on the rotation of the driving component 10.

[0029] In order to drive the rolling door 20 to rise and fall, the driving assembly 10 includes a pair of door frames 11 arranged at intervals, a main rod 12 is rotatably connected between the tops of the two door frames 11, a reel 13 is coaxially connected to the periphery of the main rod 12, and the main rod 12 is driven by a servo motor; a torsion spring 50 is provided between the outer wall of the main rod 12 and the inner wall of the reel 13, the inner circle of the torsion spring 50 is fixedly connected to the outer wall of the main rod 12, and the outer circle of the torsion spring 50 is fixedly connected to the inner wall of the reel 13; after the power is turned on, the servo motor drives the main rod 12 coaxially connected to its own output shaft to rotate, and the main rod 12 then drives the reel 13 coaxially connected to it to rotate, thereby driving the rolling door 20 wound on the reel 13 to descend, during which the torsion spring 50 is continuously tightened, and when the rolling door 20 needs to be opened, the restriction of the deceleration assembly 30 on the main rod 12 is released by the unlocking assembly 40, and the main rod 12 drives the reel 13 to reverse under the action of the restoring force of the torsion spring 50, thereby automatically retracting the lowered rolling door 20.

[0030] In order to ensure the stability of the rolling door 20 when it is descending and to remind the operator of the status of the rolling door 20 at all times, the reduction assembly 30 includes a reduction wheel 31 coaxially connected to the main rod 12, and a reduction claw 32 is clamped on the top of the reduction wheel 31; the reduction assembly 30 belongs to a ratchet mechanism, and its working principle is as follows: the ratchet is fixed by a central axis, and its outer ring has a series of ratchet teeth arranged evenly at intervals. When an external force acts on the ratchet, the ratchet teeth will start to rotate due to the torque. The special shape of the ratchet teeth makes them only able to rotate in one direction and be blocked in the other direction. When the ratchet rotates, they will pass through the adjacent ratchet teeth one by one. This transmission method effectively transmits the input torque to the next ratchet to realize power transmission. This transmission method of only transmitting one ratchet at a time makes the ratchet have higher accuracy and stability when transmitting power.

[0031] In order to release the restriction of the reduction assembly 30 on the driving assembly 10 during rotation, the unlocking assembly 40 includes a lock buckle 41 which is clamped on the top of the reduction claw 32. The bottom of the lock buckle 41 is provided with hydraulic rods 42 on both sides of the reduction claw 32. The piston end of the hydraulic rod 42 fits with the bottom of the lock buckle 41. The hydraulic rod 42 is started to lift the lock buckle 41 through its piston end, and the lock buckle 41 then drives the reduction claw 32 away from the reduction wheel 31, thereby releasing the restriction of the reduction assembly 30 on the rotation of the main rod 12.

[0032] When the fast automatic rolling shutter door provided in the utility model is used, the driving assembly 10 is provided to drive the rolling shutter 20 to rise and fall, and then the rolling shutter 20 at the lowest point is automatically retracted through the torsion spring 50. Specifically, after the power is turned on, the servo motor drives the main rod 12 coaxially connected to its own output shaft to rotate, and the main rod 12 then drives the reel 13 coaxially connected to it to rotate, thereby driving the rolling shutter 20 wound on the reel 13 to descend. During this period, the torsion spring 50 is continuously tightened. During this period, when the rolling shutter 20 needs to be opened, the restriction of the deceleration assembly 30 on the main rod 12 is released by the unlocking assembly 40. The main rod 12 drives the reel 13 to reverse under the action of the restoring force of the torsion spring 50, thereby automatically retracting the lowered rolling shutter 20; the deceleration assembly 30 is used to ensure the stability of the rolling shutter 20 when it descends. Specifically, the deceleration assembly 30 belongs to a ratchet mechanism, and its working principle is as follows: the ratchet is fixed by a central axis, and its outer ring has a series of uniform The ratchets are arranged at intervals. When an external force acts on the ratchet, the ratchets will start to rotate under the action of torque. The special shape of the ratchets makes them only rotate in one direction and are blocked in the other direction. When the ratchet rotates, they will pass through the adjacent ratchets one by one. This transmission method effectively transmits the input torque to the next ratchet to achieve power transmission. This transmission method of only transmitting one ratchet at a time makes the ratchet have higher accuracy and stability when transmitting power. In addition, the "click" sound emitted by the reduction claw 32 when it passes through the surface of the reduction wheel 31 reminds the operator of the status of the rolling door 20 at all times, and then the unlocking component 40 is used to release the restriction of the reduction component 30 on the rotation of the drive component 10. Specifically, the hydraulic rod 42 is started, and the lock buckle 41 is lifted through its piston end. The lock buckle 41 then drives the reduction claw 32 away from the reduction wheel 31, thereby releasing the restriction of the reduction component 30 on the rotation of the main rod 12.
