The invention belongs to the technical field of door locks, and particularly relates to a silent door lock. The silent door lock comprises a first lock block and a second lock block. The included angle between a first slope on a limiting block designed in the silent door lock and the end face of a door frame and the included angle between a second slope on the limiting block and the end face of the door frame are small, when a square bolt impacts the first slope on the limiting block, due to the fact that the impact face is the slope, therefore, the impact sound is smaller than that of vertical impact, and the noise caused by the first-time impact in the background is reduced to a certain extent; after the limiting block slides to be disengaged from the square bolt, the square bolt can cross the first slope on the limiting block, at the moment, the sliding block slides towards the outer side of a mounting shell under the action of a reset spring, meanwhile, the limiting block resets under the action of a return spring, so that the second slope on the limiting block is matched with a slope on the square bolt; and due to the fact that the distance at which the limiting block moves out again after moving back is much smaller than the distance at which a traditional square bolt moves after being disengaged from a metal sheet, noise caused by second-time impact in the background isreduced.
本发明属于门锁技术领域，尤其涉及一种静音门锁，它包括第一锁块和第二锁块，本发明设计的限位块上的第一斜面和第二斜面与门框端面之间的夹角较小，在方形锁舌撞击限位块上的第一斜面的时候，因撞击面为斜面，所以撞击的声音相对垂直撞击要小，一定程度上降低了背景中所述的第一次撞击所带来的噪音；在限位块滑动到与方形锁舌脱离后，方形锁舌就会越过限位块上的第一斜面，此时滑块复位弹簧的作用下向安装壳外侧滑动，同时限位块在回位弹簧的作用下复位，使得限位块上的第二斜面与方形锁舌上的斜面配合；因限位块回移后再次移出的间距相对传统的方形锁舌在与金属片脱离后移动的间距要小很多，降低了背景中第二次撞击所带来的噪音。
