摘要： A top-and-bottom latch structure for a lock mainly includes a lock formed by a casing, and a lock tongue, a lock core, a handle spindle, and other components disposed in the casing. The handle spindle is provided with a first and a second protruding rod disposed at different angles, and is respectively provided with a first and a second braking piece above and under the handle spindle, so that the two braking pieces are respectively clamped by the protruding rods. The top-and-bottom latch structure for a lock further includes: two fixing members, respectively connected to the braking pieces; and tact switches, connected to a door panel by the fixing members via connecting rods. Therefore, when the door is closed, the tact switches once touching the door frame are embedded into the door frame and the fixing members move downwards to rotate the handle spindle and lock the lock tongue. When the handle spindle is pressed down, the lock tongue is drawn back, and at the same time drives the fixing members to move upwards to make the lock tongue be disengaged from the door frame to unlock, and thus the lock has the effect of the top-and-bottom latch, thereby improving the safety of the lock.
摘要翻译：用于锁的顶部和底部闩锁结构主要包括由壳体形成的锁和锁舌，锁芯，手柄主轴和布置在壳体中的其它部件。手柄主轴设置有以不同角度设置的第一和第二突出杆，并且在手柄主轴上方和下方分别设置有第一和第二制动片，使得两个制动片分别由突出的杆。用于锁的顶部和底部闩锁结构还包括：分别连接到制动片的两个固定构件; 和触控开关，通过连接杆通过固定构件连接到门板。因此，当门关闭时，触摸门框的触控开关被嵌入门框中，并且固定构件向下移动以旋转手柄主轴并锁定锁舌。当手柄主轴被按下时，锁舌被拉回，并同时驱动固定部件向上移动，使锁舌从门框上脱离开锁，因此锁具有顶部和底部闩锁，从而提高锁的安全性。
