Labor-saving mistaken door opening prevention device
The invention discloses a labor-saving mistaken door opening prevention device, and belongs to the technical field of door stoppers. The labor-saving mistaken door opening prevention device comprisesa door body, a rotary stretching part, a handle, a secondary door stopper and a primary door stopper; and a rotating groove is formed in the portion, close to the left side, of the door body, a rope groove is formed in the bottom end of the rotating groove, a door stopper groove is formed in the lower end of the rope groove and penetrates through the rear side of the door body, a handle shaft holeis formed in the rear end face of the door body and penetrates through the front side and the rear side of the door body, and the handle shaft hole is coaxial with the rotating groove. According to the device, wind blowing and ordinary human accidentally touch can not make the secondary door stopper and the primary door stopper disconnected, the mistake opening probability of a door is reduced, human body work when an operator separates the secondary door stopper from the primary door stopper is reduced, work needed for rotating the door body when the operator closes the door is omitted, operation burdens and operation time of the operator are reduced, work required for the operator to rotate the handle is reduced, and interference between the handle and mechanisms such as a lock on the left side of the handle is effectively avoided.
本申请公开了一种省力的防误开门，属于门吸技术领域。一种省力的防误开门，包括门体、转动拉伸部、把手、子门吸和母门吸。门体靠近左侧的内部开设有转动槽，转动槽底端开设有绳槽，绳槽下端开设有门吸槽，门吸槽贯穿门体后侧，门体后端面开设有把手轴孔，把手轴孔贯穿门体前后两侧，把手轴孔与转动槽同轴，它可以实现风力吹动和普通人力误碰无法时子门吸与母门吸断开，减少了门的误开几率，降低操作者将子门吸与母门吸分离时的人体做功，省去操作者关门时转动门体所需的做功，减轻了操作者的操作负担及操作时间，减少操作者转动把手所需的做功，有效避免把手与把手左侧的锁头等机构干涉。
