Door lock device capable of saving labor during door closing
The door lock device comprises an upper shell, a lower shell and a locking body, a mounting cavity is formed in a shell formed by the upper shell and the lower shell, the locking body is arranged in the mounting cavity, a lock hole allowing a door hook to be inserted is formed in the upper shell, and the door lock device further comprises a driving plate and a spring. A driving plate is arranged on one side of the locking body, a spring is arranged on the side, back on to the locking body, of the driving plate in a matched mode, the spring exerts acting force abutting against the locking body on the driving plate, the locking body is provided with an equidistant upper arc face and a variable-pitch lower arc face, and when the driving plate makes contact with different positions of the equidistant upper arc face, the variable-pitch lower arc face abuts against the variable-pitch upper arc face. The distance between the driving plate and the locking body shaft of the locking body is kept unchanged, and when the driving plate makes contact with the variable-pitch lower arc face, under the action of the spring, acting force for assisting in closing the door is applied to the locking body. The door lock device is small in door closing force, convenient to operate and capable of resetting after door closing after false triggering, and maintenance is not needed.
本发明提出了一种关门省力的门锁装置，包括上壳体、下壳体和锁定体，所述上壳体与下壳体组成的壳体内部具有安装腔，所述安装腔内设置有锁定体，所述上壳体上开设有可供门钩插入的锁孔，还包括驱动板、弹簧，所述锁定体的一侧设有驱动板，所述驱动板背向锁定体的一侧配设有弹簧，所述弹簧对驱动板施加一朝向锁定体抵靠的作用力，所述锁定体上具有等距上圆弧面、变距下圆弧面，所述驱动板与等距上圆弧面的不同位置相接触时，驱动板与锁定体的锁定体轴之间的距离保持不变，所述驱动板与变距下圆弧面相接触时，在弹簧的作用下，对锁定体施加一辅助关门的作用力。该门锁装置不仅关门力小，便于操作，而且在误触发后再关门能够复位，无需维护。
