Referring initially to fig. 1-6, and with appropriate reference to fig. 7-8, an embodiment of the present invention provides a lock assembly 100 for selectively locking a door body 200 to a door post 300.

The lock assembly 100 includes a lock cylinder 10, a lock catch 20, a first actuator 30, and a second actuator 40. It should be noted that the lock cylinder 10 and the lock catch 20 of the present embodiment are both a conventional lock cylinder and lock catch as shown in fig. 1.

As shown in fig. 1, the lock cylinder 10 includes a lock body 11 fixed to the doorpost 300, and a passive portion 12 and a latch 13 movably connected to the lock body 11. The lock body 11 has a lock slot 111, and the latch 13 is disposed in the lock slot 111 and is interlocked with the passive portion 12 to move from a locking position to an unlocking position when the passive portion 12 is actuated. In this embodiment, the passive portion 12 is a shifting block and is adapted to be actuated along a vertical second direction, and the latch 13 is also extended and retracted in the lock slot 111 along the second direction and located at the locking position and the unlocking position, respectively. In addition, the passive part 12 is farther from the door body 200 than the latch 13, in other words, the passive part 12 is located at a position further back than the latch 13.

It should be noted that the linkage relationship between the latch 13 and the passive part 12 may be: the driven part 12 slides after being actuated, and drives the lock tongue 13 to slide through the inclined surface, but not limited to this, and other transmission structures may be used inside the lock cylinder 10 to drive the lock tongue and the lock tongue to slide. In addition, the lock cylinder 10 may further include an elastic reset mechanism inside, so that the passive portion 12 is reset when not actuated, and the latch 13 is also reset to the locking position.

With continued reference to fig. 1, the latch 20 is fixedly connected to the door 200 and is adapted to establish and release a stopping engagement relation with the latch 13 along a first direction when the latch 13 is located at the locking position and the unlocking position, respectively. It is self-evident that when the latch tongue 13 and the latch buckle 20 establish the stop mating relationship, the latch buckle 20 is already inserted into the lock groove 111, and the door body 200 is locked with respect to the doorpost 300 and is in a closed state; when the latch tongue 13 and the latch buckle 20 are released from the stop engagement relationship, the latch buckle 20 can freely exit from the lock groove 111, and the door body 200 is unlocked relative to the door post 300 and is in a door-opening state. In this embodiment, the first direction is horizontal and perpendicular to the second direction.

Referring to fig. 4 and 6, the first actuating member 30 is slidably coupled to the doorpost 300 along the second direction to slide relative to the lock body 11 along the second direction and actuate the passive portion 12. In this embodiment, the first actuating member 30 actuates the driven portion 12 when sliding to a second engagement position. When the second matching position is located, the first actuating piece 30 is overlapped with the orthographic projection of the lock cylinder 10 along the first direction.

In a specific structure, the first actuating member 30 is a sheet metal member having a bent structure, and is provided with a receiving portion 31 and a pushing portion 32. The receiving portion 31 extends along the first direction and has a receiving surface perpendicular to the second direction. The abutting portion 32 has an abutting surface perpendicular to the second direction, and is used for surface-matching with the passive portion 12 of the lock cylinder 10, so as to avoid damaging the passive portion 12.

Referring to fig. 5 and 6, the second actuator 40 is rotatably connected to the door body 200 and has a rotation axis perpendicular to the sliding direction of the first actuator 30, i.e., a rotation axis parallel to the first direction. When the second actuating member 40 rotates to a first engagement position, the first actuating member 30 is toggled to drive the first actuating member 30 to slide and actuate the driven part 12, and when the second actuating member 40 is located at the first engagement position, the orthographic projection of the second actuating member 40 and the lock cylinder 10 along the first direction is not overlapped, so that the second actuating member 40 is suitable for opening with the door body 200 and is far away from the door post 300.

In a specific structure, the door body 200 is provided with a handle (not shown in the figure) rotatably connected with the door body 200, and a rotation axis of the handle is parallel to the first direction. The second actuator 40 is a sheet metal part with a bent structure, and has a second connecting portion 41 and a toggle portion 42, the second connecting portion 41 is connected with the handle in a rotation-stopping manner, and the toggle portion 42 extends along the first direction and has a transition arc surface 42A. When the second actuating member 40 rotates, the transition arc surface 42A is engaged with the line surface of the abutted surface and abuts against the first actuating member 30 to slide. Because the transition arc surface 42A is suitable for being matched with the line surface of the supported surface, and because the shifting portion 42 and the supported portion 31 both extend along the first direction, the contact range is large enough, the shifting process is smooth, and the sliding process of the first actuating element 30 is stable.

It can be seen that the lock assembly 100 of the present embodiment provides two actuating members, the first actuating member 30 slides relative to the lock body 11 to actuate the driven portion 12 of the lock cylinder 10, the second actuating member 40 rotates relative to the door body 200 and is adapted to toggle the first actuating member 30 to drive the lock cylinder to slide, and furthermore, the second actuating member 40 does not coincide with the orthographic projection of the lock cylinder 10 along the first direction when the first actuating member 30 is toggled, i.e. is spaced from each other. In this way, the first actuating member 30 is switched to greatly shorten the length of the second actuating member 40, so that the second actuating member 40 moving with the door body 200 and the door body 200 does not interfere with the key cylinder 10 during the door opening process of the door body 200. Therefore, the lock assembly 100 of the present embodiment can effectively ensure successful door opening and reduce the possibility of the second actuating member 40 accidentally injuring a human body.

It should be noted that, in the present embodiment, when the toggle portion 42 of the second actuating member 40 does not abut against the abutted portion 31 of the first actuating member 30, the first actuating member 30 naturally slides down and resets along the second direction under the action of gravity, so as to facilitate the next unlocking operation.

Preferably, in the present embodiment, the first actuating element 30 has a first connecting portion 33, and the first connecting portion 33 is perpendicular to the first direction and is provided with a first waist hole 33A extending along the second direction. The lock assembly 100 also includes a connector 50 and a limit screw 60. The connecting member 50 is fixedly connected to the doorpost 300, and the limit screw 60 passes through the first waist hole 33A and is in threaded fit with the connecting member 50, so that the first actuating member 30 is in sliding fit with the connecting member 50 only along the second direction, and the structure is simple and reliable.

Preferably, the extended length of the first waist hole 33A is further configured to limit the sliding stroke of the first actuator 30, so that the sliding stroke of the first actuator 30 can be effectively limited by configuring the extended length of the first waist hole 33A, and the first actuator is prevented from sliding excessively to actuate the passive portion 12 excessively and damage the passive portion 12.

Further, the lock assembly 100 further includes a set screw 70 for screwing the lock body 11 of the key cylinder 10 to the connector 50. In addition, connecting piece 50 is equipped with the edge the second waist hole (not shown in the figure) that the second direction extends, second waist hole is used for adjusting connecting piece 50 rigid coupling in behind the gatepost 300 be in the ascending position of second direction to make connecting piece 50 possess the function of adjusting the mounted position in the second direction, be convenient for make hasp 20 get into lock core 10 along the first direction comparatively accurately after the installation, effectively avoided because the installation error of the door body 200 leads to when hasp 20 gets into lock core 10 after the actual installation, easily collide with the lock body 11 of lock core 10 and lead to the condition that hasp 20 buckles and damages.

Referring next to fig. 7-8, the present embodiment also provides a cabinet 1000 comprising a cabinet door and a cabinet body hinged to each other. The cabinet door comprises the door body 200, and the cabinet body comprises a bolt 13 door post 300.

In addition, the cabinet 1000 also includes a lock assembly 100 as described in previous embodiments. The door body 200 is selectively latched to the doorpost 300 by the latch assembly 100. In this embodiment, the hinge shaft of the cabinet door and the cabinet body is vertical, the sliding direction of the first actuating member 30 is vertical, and the first direction is horizontal. It goes without saying that since the cabinet 1000 of the present embodiment employs the lock assembly 100 of the foregoing embodiment, all advantages thereof are inherited.

The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments of the utility model or portions thereof through a reasonable analysis, inference or limited experimentation, in light of the common general knowledge, the common general knowledge in the art and/or the prior art, are intended to be within the scope of the utility model.
