The invention provides electromagnetic switch control equipment for a fireproof door, and mainly relates to the field of fireproof door control. The electromagnetic switch control equipment for the fireproof door comprises a sliding rail, the sliding rail is fixedly installed on a door frame on the upper portion of the fireproof door through bolts, a locking device is fixedly installed at one end of the sliding rail through bolts, a sliding block is installed in the sliding rail in a sliding mode, the locking device comprises a fixing frame, and a circuit board is fixedly installed in the fixing frame. An electromagnet is fixedly installed in the fixing frame, a spring bolt is arranged at one end of the electromagnet, and a rocker arm is rotationally installed in the fixing frame. The equipment has the beneficial effects that the structure is simple, energy is saved, the electromagnet is integrated with the locking mechanism, and the electromagnet does not need to be powered up at ordinary times; by utilizing the characteristic that a plastic material can be stressed to generate elastic deformation, the door can be automatically reset and locked without other operations when the door is opened; the internal pressure of the structure is concentrated in a very small area, so that cast aluminum materials are not used, the door closer is made of poly-carbon or ABS materials, and the cost is lower than that of a traditional door closer.
Description
technical field [0001] The invention mainly relates to the field of fire door control, in particular to a fire door electromagnetic switch control device. Background technique [0002] A fire door is a fireproof device that closes automatically in the event of a fire to prevent the fire from spreading. The normally closed fire door needs to be opened manually when people pass through, and it will be automatically closed under the action of the door closer after the person passes, but sometimes people need to pass through frequently. In order to facilitate the passage of people, we hope that the normally closed fire door can Although there are some door closers with the function of stopping the door, that is, the door does not close automatically after the door is opened at a certain angle, but for safety reasons, such door closers are prohibited from being used on fire doors. of. At present, in order to keep the normally closed fire door normally open under certain conditi...
