However, when the lock tongue of the conventional lock moves from the unlocking position to the locking position, the lock tongue protrudes outward for a certain distance relative to the housing, so that a deep locking groove needs to be formed in the door frame relative to the lock tongue for the lock tongue to extend into, but the door frame with a thin thickness cannot be provided with the deep locking groove, or the locking groove of the conventional door frame needs to be deepened again to match the movement of the lock tongue, so that the conventional lock has many limitations and inconvenience in use.

Disclosure of Invention

Therefore, the present invention develops a technical solution that can improve the existing drawbacks in view of the existing lock structure and the inconvenience and limitation in use.

The present invention provides a lock, which can keep the spring bolt not protruding out of the housing when the spring bolt is from the unlocking position to the locking position, so that the lock can be matched with a door frame with a thinner thickness without deepening the locking groove on the door frame, thereby improving the practicability and the convenience of the lock.

To achieve the above object, the present invention provides a lock device, which comprises:

a housing;

a lock tongue which is telescopically and movably arranged in the shell and can protrude out of the shell;

a bolt seat fixedly connected with the bolt and capable of moving relative to the shell;

a linkage piece movably arranged in the shell, connected with the bolt seat and forming a relative displacement with the bolt seat, wherein, a moving groove which can make the linkage piece move relative to the bolt seat is arranged on the bolt seat, one end of the linkage piece can movably extend into the moving groove, and a hook part which can be buckled with the inner wall of the moving groove is formed on the linkage piece; and

and the locking mechanism is arranged on the shell and can be abutted against the linkage part so as to position the lock tongue seat and the lock tongue at a locking position.

By the technical means, when the linkage piece moves from the unlocking position to the locking position, the lock tongue can keep the original position relative to the shell without extending and moving, so that the lock can be suitable for a structure with a thinner door frame or a shallower clamping groove on the door frame, and the deep clamping groove does not need to be additionally dug, and the use elasticity and the use convenience of the lock can be improved.

In the first embodiment of the present invention, the linkage member 30 includes a pivot member 32 and a sliding member 34, the pivot member 32 is pivotally connected to the latch base 22, the sliding member 34 is slidably connected to the pivot member 32, the moving slot 40 is disposed on the pivot member 32 of the linkage member 30, and one end of the sliding member 34 of the linkage member 30 movably extends into the moving slot 40 and forms a hook portion 342 capable of being engaged with the inner wall of the moving slot 40.

The locking mechanism 60 is disposed on the housing 10 and can abut against the linking member 30 to limit the linking member 30 from moving relative to the housing 10, so as to position the bolt seat 22 and the bolt 20 at the locking position.

The linking mechanism 50 is rotatably disposed on the housing 10 and connected to a handle, and can be driven by the handle to rotate relative to the housing 10, the linking mechanism 50 is provided with a shifting block 52 protruding thereon for driving the linking member 30 to move relative to the housing 10, wherein, a moving part 54 driven by the shifting block 52 and moving relative to the housing 10 is further disposed in the housing 10, a buckle block 542 capable of being buckled with the linkage 30 is disposed on the moving part 54, and a buckle slot 346 capable of being buckled with the buckle block 542 is concavely disposed on the sliding part 34 of the linkage 30, so that when the handle is rotated, the shifting block 52 can drive the moving member 54 to move relative to the housing 10, and by means of the mutual engagement of the locking block 542 on the moving member 54 and the locking groove 346 on the sliding member 34, the sliding member 34 is driven to move relative to the housing 10, so as to further drive the pivot member 32, the bolt seat 22 and the bolt 20 to move relative to the housing 10 and retract into the housing 10.

A sliding groove 24 is concavely arranged on the bolt seat 22, a stop 26 is convexly arranged in the sliding groove 24, so that an inverted U-shaped sliding channel is formed in the sliding groove 24, and a propping block 36 which can slide in the sliding channel and can prop against the stop 26 is convexly arranged on the linkage piece 30.

When the lock of the present invention is used, please refer to fig. 3 and fig. 4, a lock core mechanism 70 is further disposed on the housing 10, the lock core mechanism 70 is disposed with a rotatable push block 72, both sides of the lock core mechanism 70 are respectively disposed with a turn button and a key hole, so that the push block 72 can be rotated by rotating the turn button or inserting the key, when the push block 72 rotates, the push block 72 can push against the sliding member 34 of the linking member 30 to move the sliding member 34 relative to the housing 10, and the linking member 30 can also pivot relative to the housing 10 and the lock tongue seat 22 by the pivotal connection of the pivotal member 32 and the lock tongue seat 22, because the sliding member 34 can move relative to the moving slot 40 on the pivotal member 32, when the sliding member 34 is pushed by the push block 72 and moves relative to the housing 10, the pivotal member 32, the lock tongue seat 22 and the lock tongue 20 can keep the original position relative to the housing 10 and not move relative to the housing 10, at this time, the abutting block 36 on the sliding element 34 moves along the sliding path in the sliding groove 24 to bypass the stop 26, and one end of the locking arm 62 is caught in the locking groove 344, so that the sliding element 34 cannot move reversely due to the abutting of the locking arm 62, and thus the lock tongue 20 can be positioned to protrude out of the housing 10 without retracting into the housing 10, and thus the lock is in the locking position.

When the lock is to be unlocked, the lock core mechanism 70 is rotated reversely by rotating the knob or inserting a key into the keyhole, so as to rotate the push block 72 reversely, when the push block 72 rotates reversely, the linkage 30 pivots reversely by the push block 72, and pushes the locking arm 62 to separate from the position abutting against the locking groove 344, so as to release the locked state of the linkage 30, so as to drive the sliding member 34 to move reversely, and the abutting block 36 on the sliding member 34 moves to the other side of the stopper 26 along the sliding path in the sliding groove 24, bypassing the stopper 26, so as to return the linkage 30 to the unlocked position, at this time, the hook 342 at one end of the sliding member 34 of the linkage 30 is engaged with the inner wall of the moving groove 40 on the pivoting member 32, so as to refer to fig. 5 again, if the handle is rotated, the moving block 52 of the linkage 50 drives the linkage 30 to move towards the inner side of the housing 10 through the moving member 54, then, the hook 342 of the sliding element 34 is engaged with the inner wall of the moving slot 40 to drive the bolt seat 22 and the bolt 20 to move toward the inside of the housing 10, so that the bolt 20 is retracted into the housing 10, and thus, the user can open the door panel for people to pass through.

In addition, when someone unlocks the lock cylinder mechanism 70 and rotates the handle at the same time, please refer to fig. 5 and 6, at this time, the shifting block 52 will drive the moving member 54 to move inward relative to the housing 10 first, so that when the lock cylinder mechanism 70 is rotated to drive the linking member 30 to move and release the locking state, because the moving member 54 has moved inward of the housing 10 first, when the sliding member 34 of the linking member 30 moves to the unlocking position, the catch 542 on the moving member 54 will not catch on the catch 346 on the sliding member 34, after releasing the handle, the catch 542 on the moving member 54 moving back will push against the sliding member 34, at this time, because of the stop 26 disposed in the sliding groove 24 on the latch base 22, when the linking member 30 is pushed against by the moving member 54, the stop 26 and the abutment block 36 abut against each other, the linking member 30 is restricted from moving outward of the housing 10, and the linking member 30 can only pivot relative to the latch base 22, meanwhile, the design of the height of the stop 26 can be utilized, so that the abutting block 36 on the sliding member 34 is not enough to bypass the stop 26, but the fastening block 542 on the moving member 54 is fastened in the fastening groove 346 of the sliding member 34, so that the linked member 30, the latch bolt seat 22 and the latch bolt 20 can retract and move relative to the housing 10 through the transmission of the shifting block 52 and the moving member 54 by rotating the handle, so as to open the door panel.

Referring to fig. 7 to 9, in a second embodiment of the present invention, the moving slot 40A is disposed on the latch seat 22A, the linking member 30A is an integrally formed structure, one end of the linking member 30A movably extends into the moving slot 40A, and a hook 31A capable of being engaged with an inner wall of the moving slot 40A is formed at the end, and the locking mechanism 60A includes a locking arm 62A pivotally disposed on the housing 10, a locking protrusion 64A is disposed on the locking arm 62A, and a locking block 33A capable of abutting against the locking protrusion 64A on the locking arm 62A is disposed on the linking member 30A.

Thus, when the lock is located at the unlocking position as shown in fig. 8, the locking block 33A on the interlocking member 30A is located at one side of the locking projection 64A on the locking arm 62A relative to the inside of the housing 10, and when the lock core mechanism 70 is rotated, the pushing block 72 of the lock core mechanism 70 pushes the interlocking member 30A to move toward the outside of the housing 10 and simultaneously pushes the locking arm 62A to pivot relative to the housing 10, so that the locking block 33A on the interlocking member 30A reaches the other side of the locking projection 64A through the position of the locking projection 64A, and thus, the interlocking member 30A, the latch holder 22A and the latch 20 are restricted from retracting and moving relative to the inside of the housing 10 by the mutual abutting of the locking block 33A and the locking projection 64A, and the lock is located at the locking position.

At this time, when the interlocking member 30A moves toward the outside of the housing 10, the hook portion 31A at one end of the interlocking member 30A moves relative to the moving groove 40A due to the provision of the moving groove 40A, and the latch holder 22A and the latch 20 are held at the positions not moved relative to the housing 10, and do not move to protrude relative to the housing 10.

Referring to fig. 10 to 12, in a third embodiment of the present invention, the moving slot 40B is disposed on the latch seat 22B, the linking member 30B is an integrally formed structure, one end of the linking member 30B movably extends into the moving slot 40B, and a hook 31B capable of being engaged with an inner wall of the moving slot 40B is formed at the end, the locking mechanism 60B includes a locking protrusion 64B protruding from the housing 10, a locking member 38 capable of abutting against the locking protrusion 64B is disposed on the linking member 30B, wherein the locking member 38 is movably disposed on the linking member 30B and capable of abutting against the pushing block 72 of the lock core mechanism 70 to move relative to the linking member 30B, and a spring 39 abutting against the locking member 38 is disposed on the linking member 30B.

Therefore, when the lock cylinder mechanism 70 is rotated, the pushing block 72 of the lock cylinder mechanism 70 pushes the locking member 38 to move relative to the linking member 30B, and simultaneously pushes the linking member 30B to move toward the outside of the housing 10 relative to the housing 10, and due to the movement of the locking member 38 relative to the linking member 30B, the locking member 38 can bypass the locking protrusion 64B on the housing 10, and compress the spring 39, and after the locking member 38 bypasses the locking protrusion 64B, the spring 39 pushes the locking member 38 back to the position abutting against the locking protrusion 64B, so that the mutual abutting of the locking protrusion 64B and the locking member 38 can limit the linking member 30B from moving toward the inside of the housing 10, and the lock tongue seat 22B and the lock tongue 20 are positioned at the position extending out of the housing 10 and cannot retract into the housing 10, so that the lock is positioned at the locking position.

At this time, since the hook 31B of the linking member 30B can move relative to the moving groove 40B, when the linking member 30B moves toward the outside of the housing 10, the latch bolt seat 22B and the latch bolt 20 can be kept at the original position relative to the housing 10, and do not extend and move again toward the outside of the housing 10 along with the linking member 30B.

Referring to fig. 13 to 15, in a fourth embodiment of the present invention, the moving slot 40C is disposed on the latch holder 22C, the linking member 30C is an integrally formed structure, one end of the linking member 30C movably extends into the moving slot 40C, the linking member 30C is formed with a hook 31C capable of being engaged with the inner wall of the moving slot 40C, the moving slot 40C is disposed with a spring 42 having two ends respectively abutting against the inner wall of the moving slot 40C and one end of the linking member 30C, the locking mechanism 60C includes a locking arm 62C capable of moving relative to the housing 10, the linking member 30C is recessed with a locking slot 344C into which one end of the locking arm 62C extends, the locking slot 344C is formed with an opening facing one side of the locking arm 62C, and a side of the opening facing the latch holder 22C is an inclined plane.

Thus, when the locking arm 62C is pushed relative to the housing 10, one end of the locking arm 62C is inserted into the locking groove 344C of the linking member 30C, and the locking arm 62C pushes against the inclined surface of the opening of the locking groove 344C, so that the linking member 30C moves relative to the housing 10 along the moving groove 40C, and compresses the spring 42, after the locking arm 62C moves to the position of being clamped in the locking groove 344C as shown in fig. 15, the linking member 30C is limited from moving relative to the housing 10 by the mutual abutting of the inner wall surfaces of the locking arm 62C and the locking groove 344C, so that the latch tongue 20 and the latch tongue seat 22C are positioned at the locking position, and after the locking arm 62C moves reversely to leave the locking groove 344C, the linking member 30C can be pushed reversely to the original position as shown in fig. 14 by the restoring elastic force provided by the spring 42, so as to release the locking state of the lock.

When the lock is switched from the unlocking position to the locking position, the lock tongue 20 can keep the original position without extending and moving relative to the shell 10 due to the relative movement of the

linkage members

30,30A,30B and 30C relative to the lock tongue seats 22,22A,22B and 22C, so that the lock can be suitable for the structure with a thinner door frame or a shallower clamping groove on the door frame, and the clamping groove does not need to be additionally dug deeply, thereby improving the use elasticity and the use convenience of the lock.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
