Description
Technical field
The utility model relates to the doorframe anti-jamming device.
Background technology
At present, the electronic or pneumatic keying of the normal employing of the gate open of elevator, bus or big bus, especially in closing course, when running into slight resistance, door can not in time be withdrawn, and causes the personal injury phenomenon to happen occasionally.
Summary of the invention
The purpose of this utility model is: a kind of doorframe anti-jamming device is provided, and this anti-jamming device is installed in the doorframe outer side edges, and when meeting obstructions in the doorframe closing course, anti-jamming device action in time allows the motor counter-rotating drive the doorframe withdrawal, guarantees personal safety.
Technical solution of the present utility model is: this anti-jamming device is made up of microswitch, microswitch collision block, by the anti-pinch support microswitch is installed at the doorframe inner side edge, the microswitch collision block that cooperates with microswitch is installed on the sliding axle, sliding axle is installed on the anti-pinch support, one end of sliding axle is installed back-moving spring, and the anti-pinch pressing plate is installed on the sliding axle through back-moving spring by screw.
In the doorframe anti-jamming device of the present utility model, the anti-pinch enclosure is installed on doorframe on anti-pinch pressing plate outer side edges.
During use, in the doorframe closing course, when the anti-pinch cover meets obstructions, anti-pinch cover interlock anti-pinch pressing plate extruding sliding axle, the microswitch collision block touches the microswitch top sheave, triggers microswitch and drives the doorframe withdrawal by the motor counter-rotating.
The utility model is simple in structure, is quick on the draw, and reduces risk, improves safety, ensures that the person is injury-free.
