Hand-pinching prevention wood door

Abstract

The invention discloses a hand-pinching prevention wood door which comprises a door frame and a movable door body. The left side edge of the door frame and the left side face of the movable door bodyare connected through hinges, and common pinching-prevention devices are further arranged between the left side edge of the door frame and the left side edge of the movable door body. A circuit switchis mounted on the front surface of the right side edge of the door frame. A standby pinching-prevention device is arranged at the right end of the lower surface of the upper side edge of the door frame. The common pinching-prevention devices comprise first magnets and first electromagnets. The standby pinching-prevention device comprises a pinching-prevention plug, a pin shaft, a second electromagnet, a second magnet and a reset spring. By utilizing repulsive force between the electromagnets, the door closing speed is decreased when the wood door is accidentally closed; and through the effectof the standby pinching-prevention plug, after the power outage, the pinching-prevention plug can be opened automatically to achieve the pinching prevention purpose.

Description

technical field [0001] The invention relates to the field of safety equipment, in particular to an anti-pinch wooden door. Background technique [0002] With the improvement of living standards, more and more people use exquisite wooden doors in home decoration. The wooden doors on the market now mainly include composite doors, solid wood doors and full wooden doors. In daily life, there are often doors that get caught The situation arises. Tracing it to its cause, it can be attributed to the abnormal closing of the door by non-human force (such as strong wind), or the negligence of the person who closes the door. [0003] Among the currently authorized patents, such as the invention with the application number: "201721351361.6", after using infrared rays to sense foreign matter, by closing the electromagnet, the mutual repulsion of the electromagnet after energization can achieve the purpose of preventing hand pinch, but the equipment cost In addition, once the circuit fa...
