The present application relates to a door opener, comprising a frame, the frame is provided with a drive motor, the drive motor is provided with a first drive wheel, the side wall of the drive wheel is provided with a plurality of installation holes, the installation holes are slidably installed with first gear teeth, and the installation holes The bottom of the hole is connected with the first gear teeth through a spring, the reel is equipped with a second driving wheel, the second driving wheel is provided with a second gear tooth meshing with the first gear teeth, the frame is provided with a limit mechanism, and the wall is provided with a switch. When the rolling shutter door is opened, the clothes of the human body are hung on the rolling shutter door to increase the weight of the rolling shutter door. The increased weight will cause the second gear teeth to press the first gear teeth into the installation hole, so that the rolling shutter door stops opening, and people remove the clothes from the rolling shutter door. After taking it off, the elastic force of the spring re-supports the first gear teeth to drive the second drive wheel to rotate to open the rolling shutter door.
Description
technical field [0001] The present application relates to the field of door auxiliary equipment, in particular to a door opener. Background technique [0002] Rolling shutter door is a kind of door made of multi-joint movable door pieces connected in series. When the rolling shutter door is installed, a reel is installed horizontally above it, and one end of the rolling shutter door is fixedly connected to the reel. The guide rail, the two sides of the rolling shutter door are slidingly matched with the guide rails. When the rolling shutter door needs to be opened, people push the rolling shutter door upward, and the rolling shaft will cooperate with the thrust of the person to put up the rolling shutter door. When it needs to be closed, people directly pull down the rolling shutter door and lock it. That is, and since the rolling shutter door is heavy, a motor connected to the reel is usually installed to drive the reel to rotate, so that people can save effort when opening...
