Description

Technical Field

[0002] Rolling doors are divided into manual and electric types. Electric rolling doors are easier to open and close than manual rolling doors. Electric rolling doors are driven by a rolling door machine installed on the mounting plate, that is, the rolling door motor. The rolling door motor rolls up the drum and drives the door curtain to rise and fall. Some rolling door motors are directly exposed to the outside during installation, and external dust is prone to clogging the heat dissipation holes, reducing the heat dissipation effect of the rolling door motor. Protecting the rolling door motor with an external protective cover may cause damage to the internal components of the rolling door motor due to untimely heat dissipation.

[0003] For example, a rolling door motor safety protection device with announcement number CN219654597U has a structure including a protection component including a U-shaped plate sleeved on the motor, a slide groove and a fixing part arranged on both sides of the U-shaped plate, a rotating block on the L-shaped plate arranged on one side of the U-shaped plate, a slide rod arranged on the top plate cooperates with the rotating blocks on both sides, and the sliding rod moves up by touching the rotating block upward and rotating, so that the top plate touches the motor, and a limiting block is provided at the lower end of the rotating block to limit the angle of the rotating block, thereby fixing the sliding rod on the rotating block and allowing the top plate to be adjusted to the height corresponding to the motor. However, the rolling door motor is directly exposed to the outside. After long-term use, external dust may block the heat dissipation holes of the rolling door motor, thereby reducing the heat dissipation effect of the rolling door motor, and due to the large weight of the rolling door body, the connection between the rolling door motor and the mounting plate is subject to large tension, and the installation stability of the rolling door motor needs to be maintained.
