Technical Field
[0001] The utility model relates to the technical field of rolling shutter doors, in particular to an emergency manual release and self-locking device for rolling shutter doors. Background Art
[0002] A rolling shutter door is a special door body composed of multi-jointed movable door panels connected in series. It can rotate up and down within a fixed slide with the scroll above the door as the center to achieve the effect of winding or closing. It is commonly used in various buildings such as shops and independent garages to serve as horizontal partitions. The rolling shutter door contains an emergency manual release mechanism, so that even in the event of power outages or fire, the clutch structure on the mechanism can still be manually pulled to move the brake shaft, thereby driving the brake pads to move away from the friction body on the motor shaft, causing the rolling shutter door body to fall due to its own weight, blocking both sides.
[0003] The existing announcement number is CN211314023U, which discloses a temperature control and manual release device for a rolling shutter door, including an end cover and a brake shaft. The brake shaft passes through the end cover. A clutch rod is provided on the brake shaft on one side outside the end cover. The clutch rod is provided with a fulcrum portion that contacts the end cover. The clutch rod can rotate with the fulcrum portion as a fulcrum to move the brake shaft. A soft shaft is provided on the clutch rod, which is convenient for assembly and maintenance, and can realize manual and temperature control release and lowering of the door. In real life, as mentioned in the reference patent, the fuse part used in the emergency manual release mechanism is generally also connected to a pull ring that supports manual pulling, and the pull ring can be pulled to realize manual release of the rolling shutter door. However, the structure of the fuse part is usually fixedly installed at a certain height on the wall, which makes it difficult for shorter people to use it easily. If the installation height is too low, it is easy to be accidentally pulled by curious children, causing unnecessary release of the rolling shutter door.
[0004] Therefore, the installation height set for the fuse part in the emergency manual release and door lowering mechanism in the above-mentioned rolling door device is fixed and cannot be adjusted, which makes it impossible to adapt to the use needs of people of different heights. It also faces the risk of accidental activation of the mechanism due to unintentional human pulling. A rolling door emergency manual release and self-locking device can be designed. By starting the adjustment motor to drive the threaded rod to rotate, the lifting and lowering sliding block and sliding plate drive the height position of the fuse body to be adjusted, which can be used by people of different height requirements to prevent children from accidentally pulling the pull ring on the fuse body, causing unnecessary release and closure of the rolling door body.

When the device is in normal use, the camera 14 will monitor people in the area. When someone is too close to the fuse body 7, the sound and light alarm 12 will be controlled to sound an alarm to warn people to avoid touching the fuse body 7. When an unexpected rapid fall of the rolling shutter door body 3 occurs, the controller 11 controls the start-up drive motor 24 to drive the bidirectional screw 23 to rotate, and cooperates with the stable guidance of the guide rod 27 to control the two push plates 18 to move relatively close, further pushing the two clamping plates 17 to clamp the upper part of the stretched end of the rolling shutter door body 3, so as to avoid the sudden fall of the rolling shutter door body 3 under abnormal accidents and cause harm to the people walking on the lower side.
[0028] Through the above steps, the device can start the adjustment motor 10 to drive the threaded rod 8 to rotate, and the sliding block 9 drives the sliding plate 6 to slide up and down, thereby adjusting the height position of the fuse body 7. It can be used by people with different height requirements. By raising the position of the fuse body 7, it also avoids children accidentally pulling the pull ring on the fuse body 7 due to curiosity and play, causing unnecessary release and closure of the rolling door body 3, so as to solve the problem that the installation height of the fuse part in the emergency manual release door lowering mechanism in the existing rolling door device is fixed and cannot be adjusted, which leads to the inability to adapt to the use needs of people of different heights, and also faces the risk of accidental activation of the mechanism due to unintentional human pulling.
