Description

Technical Field

[0001] The utility model relates to the technical field of rolling door motors, in particular to an anti-slip device for a rolling door motor. Background Technique

[0002] A rolling door is composed of many parts such as a door curtain, a seat plate, a support, a reel, and a quick release switch of a manual device. It can move by arranging multi-joint movable door pieces in series. The function of the rolling door is similar to that of a wall, both playing a role of separation, and it is very widely used in daily applications. The rolling door motor is a device for controlling the lifting of the rolling door. When the rolling door motor is in use, the main stressed part of the chain on the motor is the upper chain. Therefore, the upper chain in the chain often breaks. When the chain breaks, since the lower chain part of the chain is still connected to the large and small sprockets of the rolling door motor, the large sprocket will still rotate when the chain breaks, thus driving the rolling door to descend, which is very dangerous and lacks safety, and may cause losses to property and life.

[0003] In order to solve the above technical problems, a Chinese patent with the publication number of CN220869295U in the prior art discloses an anti-slip mechanism for a rolling door motor, including a door frame. An electric motor is arranged inside the door frame. The bottom end of the electric motor is fixedly connected with a bottom plate. Two through grooves are opened inside the bottom plate. Plug plates are arranged inside both of the two through grooves. Slots are opened on both sides inside the door frame. One end of each of the two plug plates facing away from each other extends into the slots at corresponding positions respectively. A cross plate is arranged at the bottom of the bottom plate.

[0004] Although the above prior art solution improves the safety during use, the motor is directly installed on the gearbox. When the components inside the motor body fail or age, it is difficult for workers to quickly disassemble it for maintenance and repair, thus affecting the efficiency of maintenance and replacement.
