Detailed Description
An embodiment of a reversing mechanism of a latch bolt according to the present invention will be described in further detail with reference to fig. 1 to 3.
A reversing mechanism of a latch bolt comprises a lock shell 1, a latch bolt 2 penetrating out of an expansion opening of the lock shell 1, a limiting component 4 arranged in the lock shell 1 and a rotating shaft 3 rotatably arranged in the lock shell 1, wherein one end of the rotating shaft 3 is connected with the latch bolt 2, the other end of the rotating shaft is connected with a top plate 32, and the top plate 32 is abutted against the limiting component 4;
wherein, the rotating shaft 3 is also sleeved with a first spring 31, and one end part of the first spring 31 is propped against the latch bolt 2;
the limiting assembly 4 comprises a limiting plate 41, and the limiting plate 41 is rotatably arranged in the lock shell 1 through a rotating fulcrum 411;
one end of the limit plate 41 is abutted against the top plate 32, a second spring 42 for urging the limit plate 41 against the top plate 32 is arranged near the end, a rotating button 412 is arranged at the other end of the limit plate 41, and the rotating button 412 penetrates out of the lock shell 1;
when an external force acts on the rotation button 412, the limit plate 41 rotates around the rotation fulcrum 411 and compresses the second spring 42, at this time, the top plate 32 is separated from the limit of the limit plate 41, the latch bolt 2 and the rotation shaft 3 move towards the extension opening on the lock shell 1 and extend out of the lock shell 1 under the elastic force of the first spring 31, at this time, the rotation shaft 3 is rotated 180 degrees, so that the orientation of the latch bolt 2 is changed; when the rotating button 412 is loosened, the limiting plate 41 automatically resets under the action of the compressed second spring 42; thereby realizing the reversing of the latch bolt 2, and having simple structure and labor-saving and simple reversing operation; so that the lock can be simultaneously suitable for the installation of a left door and a right door;
