It should be understood that, in practical applications, the auxiliary latch fixing plate 42 and the fixing plate transmission member 43 may also be other structures than those described above, and the present invention is not limited thereto as long as the above components can achieve the above-described functions.

The latch bolt module 2 in this embodiment includes a latch bolt 201, an actuating member a, and a stopper 212. In the figure, the actuating component a includes a latch bolt rod 202 and a latch bolt limiting component 216, the latch bolt limiting component 216 is connected to the latch bolt rod 202, and the latch bolt rod 202 and the latch bolt limiting component 216 can act together under the action of an external force, specifically, the external force is applied to the latch bolt rod 202 or the latch bolt limiting component 216 through a shifting piece.

Of course, the structure of the actuating component a is not limited to this, as long as it can drive the latch 201 to extend and contract and can be abutted against the stop component 212.

Specifically, the operation mode of the operating member a may be moving, swinging, or rotating, and in the figure, the latch rod 202 and the latch stopper 216 move in the longitudinal direction (i.e., X direction) of the latch rod 202.

The latch bolt 201 is connected to the actuating component a, in the figure, both the latch bolt 201 and the latch bolt limiting component 216 are connected to the latch bolt rod 202, and when the latch bolt rod 202 and the latch bolt limiting component 216 are actuated by an external force, the latch bolt 201 is driven to extend outwards or retract inwards relative to the lock body 9. The lock body 9 is provided with a side bar 91, the side bar 91 is provided with an oblique tongue hole, and the oblique tongue 201 can penetrate through the oblique tongue hole and extend out of the lock body 9. When unlocking, the latch bolt 201 needs to be retracted inwards to the unlocking position, and when the latch bolt 201 is located at the unlocking position, the whole latch bolt 201 is usually located inside the lock body 9. When the lock is closed, the latch bolt 201 needs to extend outward to the closed position, and when the latch bolt 201 is located at the closed position, the latch bolt 201 is at least partially located outside the lock body 9.

The stopper 212 is arranged on one side of the path of motion of the moving part a, and the stopper 212 can be switched between a stop position and a non-stop position. When the stopper 212 is switched to the stop position, the stopper 212 at least partially blocks the motion path of the motion member a, thereby stopping the motion member a. When the stopper 212 is switched to the non-stop position, the stopper 212 is not in the movement path of the moving member a, and thus does not affect the movement of the moving member a.

During normal opening and closing of the lock, the stop 212 is in the stop position. When the direction change of the latch 201 is required, the stop member 212 is located at a non-stop position. The latch 201 is reversed to accommodate different door opening directions. When the latch bolt 201 is reversed, the latch bolt 201 needs to extend outward to a position (referred to as a reversing position) that is a little bit further outward than the locking position, that is, during normal locking and unlocking, the latch bolt 201 only needs to move in a small interval of the locking position and the unlocking position, and during reversing, the latch bolt 201 needs to move in a large interval of the locking position and the reversing position. Therefore, when the latch 201 is reversed, the stopper 212 needs to be switched to the non-stop position, and after the reversal is completed, the stopper 212 needs to be switched to the stop position.

When the stop member 212 is located at the stop position and the actuating member a drives the latch bolt 201 to extend outward to the locking position, the abutting surface of the actuating member a will abut against the abutting surface of the stop member 212, so that the latch bolt 201 cannot extend outward any more, and is stabilized at the locking position.

At least one of the collision surface of the acting part a and the stop surface of the stopper 212 is provided with a cushion 213, that is, the cushion 213 may be provided by the collision surface of the acting part a, the cushion 213 may be provided by the stop surface of the stopper 212, or both the cushions 213 may be provided. The cushion pad 213 may be made of silica gel or cotton pad with sound absorption and noise reduction effects.

Through setting up blotter 213, close at every turn and lock when leading to action part A's conflict face and the conflict face of stopping part 212 to contradict, the touching noise can be effectively reduced by blotter 213, consequently can reduce the noise of switch lock in-process, promotes the silence effect of lock body.

In this embodiment, the latch module 2 further includes a latch spring 205 and a spring pressing member 206. The latch bolt spring 205 is sleeved on the periphery of the latch bolt rod 202, and the latch bolt spring 205 is limited between the latch bolt 201 and the spring pressing piece 206. The position of the spring biasing member 206 remains unchanged when the latch rod 202 is retracted inward or extended outward. In the illustrated embodiment, the spring pressing member 206 is a ring-shaped structure and is disposed around the latch rod 202, but the structure of the spring pressing member 206 is not limited to the ring-shaped structure, and may be any structure as long as it can press the latch spring 205.

When the latch bolt 201 is driven to retract inward by the action of the external force, the latch bolt spring 205 is gradually compressed, and when the external force is removed, the latch bolt rod 202 and the latch bolt limiting member 216 are driven to move in the opposite direction by the elastic force of the latch bolt spring 205, so as to drive the latch bolt 201 to extend outward. Therefore, under the condition that the latch bolt spring 205 and the spring pressing piece 206 are arranged, after the lock is unlocked, the lock body can be automatically closed under the action of elastic force, so that the lock body is more intelligent and more convenient to use. Certainly, in some embodiments, the latch spring 205 and the spring pressing member 206 may not be provided, and an external force in a reverse direction is applied to the latch 201 or the latch limiting member 216 to drive the latch 201 to extend outward, so as to achieve locking.

In this embodiment, the latch bolt module 2 further includes a trigger 211, the trigger 211 is linked with the action component a, and in the figure, the trigger 211 is integrally disposed on the latch bolt limiting member 216, so that the trigger 211 is linked with the action component a.
