Description

Technical Field

[0001] The invention relates to the technical field of safety door control devices, and in particular to a safety door with a control device. Background Art

[0002] The combination of safety doors and door openers in the current market can provide users with great convenience and safety. For example, the sliding door opener is designed to control the safety door to improve the convenience and safety of door operation. The sliding door opener focuses on the automatic operation of the door, while the automatic sliding door focuses more on intelligence and safety. The safety door will drive the door to move horizontally by installing a rack and meshing with the door opener gear. The door opener has the function of automatically stopping when the door is blocked and automatically returning when the door is blocked, and the force is adjustable, thus ensuring the safety of use. The existing sliding door opener will guide the movement by driving the rack on the door, but the exposed rack is easily polluted by dust at ordinary times, and the climate in the rainy season affects it, so that the covering materials such as mud and sand stick to the rack or tooth groove. When the gear and rack are driven, the mud and sand particles will act as abrasive particles, aggravating the wear of the gear and rack, accelerating the fatigue and life decay of the parts, and the loose meshing causes vibration noise, affecting the stability and reliability of the equipment.
