Spring bolt mechanism and lock
The invention relates to a spring bolt mechanism and a lock. The spring bolt mechanism comprises a spring bolt, a movable plate and an elastic piece; the spring bolt can move in a telescopic mode, anda limiting piece is arranged on the spring bolt; the movable plate is provided with a sliding groove, and the sliding groove comprises a first groove section which is obliquely arranged relative to the movable direction of the spring bolt; the limiting piece is arranged in the sliding groove in a penetrating mode, so that linkage of the spring bolt and the movable plate is achieved; a guide inclined plane parallel to the first groove section or forming a small included angle with the first groove section is arranged on one side surface of the movable plate; one end of the elastic piece is connected with the spring bolt, and the other end of the elastic piece abuts against the side face, provided with the guide inclined plane, of the movable plate; and when the movable plate moves to pushthe spring bolt to move in a telescopic mode, the limiting piece moves in the first groove section, and the end, abutting against the side face of the movable plate, of the elastic piece moves on theguide inclined plane. In the whole locking and unlocking process, the elastic piece does not deform or deforms little, so that when the spring bolt contracts for unlocking, only the friction force between the spring bolt and a lock hole needs to be overcome, unlocking can be achieved without large torsion, and labor is saved during unlocking.
本发明涉及一种锁舌机构及锁具，包括锁舌，锁舌可伸缩移动，其上设有限位件；移动板，移动板上设有滑槽，滑槽包括相对于锁舌移动方向倾斜设置的第一槽段；限位件穿设于所述滑槽内，实现锁舌与移动板联动；移动板的一侧面上设有平行于第一槽段或与第一槽段形成小角度夹角的导引斜面；弹性件，弹性件一端与锁舌连接，另一端与移动板设有导引斜面的侧面相抵靠；其中，移动板移动，推动锁舌伸缩移动时，限位件在第一槽段内移动，弹性件抵靠移动板侧面的一端则在导引斜面上移动。在整个上锁解锁的过程中，弹性件不会发生形变或形变较少，所以锁舌收缩解锁的时候，只需要克服锁舌与锁孔之间的摩擦力，无需较大的扭力即可解锁，解锁省力。
