Embodiment 1

[0031] refer to Figure 1 to Figure 4 , a new type of rolling door lock, including a lock core 7 and a spring 71 that moves the lock core 7 toward the rolling door 3 and locks the rolling door 3. The rolling door lock also includes a cable 6 , a clutch device 5 and a motor, wherein the clutch device includes a frame body 51 , a rotating shaft 52 , a clutch assembly 53 , a disc 54 and a damping wheel 55 . The lock cylinder 7 is a straight rod slidably arranged along its length direction, and the rolling shutter door 3 is provided with a socket 31 matched with the lock cylinder 7 .

[0032] refer to Figure 2 to Figure 4 , the frame body 51 is U-shaped and forms a mounting groove 512 , and at least one cylinder 511 is disposed in the mounting groove 512 .

[0033] refer to Figure 2 to Figure 4 , the rotating shaft 52 is rotatably arranged in the installation groove 51, and the rotating shaft 52 is driven by the above-mentioned motor.

[0034] refer to Figure 1 to Figure 6...

Embodiment approach

[0042] refer to Figure 7 , the rolling door lock includes a rolling door motor 1 , an acceleration box 4 , a clutch device 5 , a cable 6 , a spring 71 and a lock cylinder 7 . Regarding the specific setting method of the lock core 7, another specific embodiment: the rolling door lock also includes a supporting block 10, a bracket 8 and at least one connecting rod 9, and the lock core 7 is provided with a concave surface 32 on the inside of the rolling door 3.

Abstract

The invention discloses a novel roller shutter door lock and an operating principle thereof, and relates to the technical field of roller shutter doors. The roller shutter door lock comprises a lock cylinder, a spring, an inhaul cable, a clutch device and a motor, wherein the spring enables the lock cylinder to move towards a roller shutter door and locks the roller shutter door. One end of the inhaul cable is connected with the lock cylinder, and the other end of the inhaul cable is connected with the clutch device. The motor is used for driving the clutch device to wind the inhaul cable, the lock cylinder is separated from the roller shutter door, and the roller shutter door is unlocked. After the motor is stopped, the inhaul cable wound by the clutch device is stretched by the spring, and the lock cylinder moves towards the roller shutter door and locks the roller shutter door. The novel roller shutter door lock and the operating principle thereof have the advantages that no extra operation is needed when the roller shutter door is unlocked or locked, only the roller shutter door needs to be lifted normally, and accordingly the roller shutter door lock can unlock or lock the roller shutter door automatically; operation is easy and the antitheft effect is good.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a novel rolling door lock and its working principle. Background technique [0002] The door leaf of the rolling door is a movable door leaf composed of multiple door panels connected in series. The door leaf is rolled up and down to realize the opening and closing of the door. At present, the opening and closing of the rolling door is realized by the rolling door motor set on the rolling door reel. Usually, the rolling door does not have a separate The door lock relies entirely on the self-locking function of the rolling door motor, which is easy to be pried open and has poor anti-theft performance. In order to improve the anti-theft performance of the rolling door, a mechanical lock is usually installed on the door leaf of the rolling door at present. Although the mechanical lock increases the anti-theft performance of the rolling door, manual operation is required for ea...
