Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following instance is used for illustrating the utility model, but is not used for limiting scope of the present utility model.
Relay-set door lock blocking device of the present utility model, comprising: the protection screen door 3 of protection screen cabinet 1 and energy and the folding of protection screen cabinet, protection screen door 3 is installed in rotation on protection screen cabinet 1 by door-hinge 4.Protection screen cabinet 1 is provided with electromagnet 2 with the folding position of protection screen door 3, and electromagnet 2 is connected with power supply by solenoid circuit 6, and power supply adopts direct current, and solenoid circuit 6 is provided with circuit breaker contact point 9.Protection screen door 3 is provided with for lock core 5 sealed with electromagnet 2 or that separate.Lock core 5 comprises door lock housing 51, door lock unshakable in one's determination 52 and elastic component, and door lock housing 51 is fixed on protection screen door 3, and door lock housing 51 is provided with a lockhole towards electromagnet; Door lock iron core 52 is slidably disposed in door lock housing 51 by elastic component, and door lock iron core 52 can stretch out and indentation lockhole.Elastic component is preferably coil tension spring 53 in the present embodiment; Coil tension spring 53 is fixed in door lock housing 51, and door lock 52 empty sets unshakable in one's determination are in coil tension spring 53, and door lock iron core 52 is provided with the boss coordinating with coil tension spring.
Further, solenoid circuit is provided with indicator lamp 7 and power interface 8, and solenoid circuit 6 is connected with power supply by power interface 8.
When broken circuit protecting equipment is during in running status, circuit breaker contact point 9 closures, indicator lamp 7 is bright, and electromagnet 2 is with magnetic, and door lock iron core 52 is moved to the left compression coil tension spring 53, makes door lock unshakable in one's determination 52 and electromagnet 2 adhesives, pins door lock, makes to protect screen door 3 not open; In the time that circuit breaker contact point 9 disconnects, indicator lamp 7 does not work, and electromagnet 2 loses electromagnetic force, and door lock iron core 52 is opened door lock under the active force of coil tension spring 53, and door is opened.
The utility model adopts the door lock assembly of electromagnet and lock core composition to make to protect screen door or to disconnect by the closed of circuit breaker contact point, makes to protect screen door cabinet sealed or separate, thereby prevents tuning error, maloperation and the accident of by mistake touching occurs, and improves safety.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
