The invention discloses a limiting device for an electric shutter. The limiting device comprises an upper beam, wherein the upper beam is of a hollow structure, a motor for driving the electric shutter is arranged in the hollow structure and is in transmission connection with a transmission tube, and the transmission tube is movably and rotatably arranged in the upper beam. A limiting block is fixedly connected onto the transmission tube, a limiting rod is arranged on the limiting block, the upper beam is fixedly connected with a support, the lower end of the support is connected with an upper limiting micro-switch, and the upper end of the support is connected with a lower limiting micro-switch. The upper limiting micro-switch and the lower limiting micro-switch are electrically connected with a controller, the controller is electrically connected with the motor, an ejection rod for ejecting the lower limiting micro-switch is arranged on the support and located at the left end of lower limiting micro-switch, and a spring is sleeved on the ejection rod. The limiting device for the electric shutter is low in cost and good in stability, the limiting rod is movably arranged on the limiting block, fine adjustment can be performed when deviation arises, an ejection block at one end of the limiting block is provided with certain radian, and when the transmission tube rotates, the limiting device can be loosened and is sensitive in response.
Description
technical field [0001] The invention relates to a limiting device for an electric shutter. Background technique [0002] Electric blinds are a kind of curtains that are widely used. They are made into the shape of venetians and are very popular among the public. The drive system of the electric blinds consists of a motor, a rope reel and a limit device. The existing limiting device for electric shutters has the problems of high cost, slow response, and poor stability, which urgently need to be solved. Contents of the invention [0003] The object of the present invention is to address the above problems and provide a limiting device for electric blinds to solve the problems of high cost, slow response and poor stability of existing limiting devices for electric blinds. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] A limit device for electric blinds, comprising an upper beam, the upper beam is a hollow str...
