Latch bolt turnover locating structure and door lock
The invention discloses a latch bolt turnover locating structure which comprises a latch bolt, a connecting rod, a limiting device, a reset elastic piece and a guide device. The connecting rod is provided with a head end and a tail end, and the connecting rod is slidably connected to the guide device; the head end of the connecting rod is rotatably connected to the latch bolt; a guide hole is formed in the limiting device, and the connecting rod is slidably arranged in the guide hole in a penetrating mode; the two ends of the reset elastic piece abut against the limiting device and the guide device separately; the latch bolt is provided with a first locating surface and a second locating surface which are connected and obliquely arranged, and the first locating surface is perpendicular to the connecting rod; the limiting device abuts against the first locating surface or the second locating surface; when a door is opened, the latch bolt is squeezed by a door frame to turn over and swing forwards, and the object that the limiting device abuts against is switched from the first locating surface to the second locating surface; the limiting device remains abutting against the second locating surface after completion of door opening action, and the situation that the latch bolt is turned over and swung backwards to reset and consequently noise is generated is avoided.
本发明公开了一种斜舌翻转定位结构，包括斜舌、连接杆、限位装置、复位弹性件和导向装置；连接杆具有首端和尾端，连接杆可滑动地连接于导向装置，连接杆的首端转动连接于斜舌；限位装置上设有导向孔，连接杆可滑动地穿设于导向孔，复位弹性件的两端分别抵接于限位装置和导向装置；斜舌具有相连接且倾斜设置的第一定位面和第二定位面，第一定位面与连接杆垂直设置，限位装置抵接于第一定位面或第二定位面；斜舌在开门时受门框的挤压而正向翻转摆动，限位装置的抵接对象由第一定位面切换至第二定位面，使限位装置在开门动作完成后保持与第二定位面相抵接，避免斜舌反向翻转摆动以复位而产生噪音。
