As shown in fig. 1 to 5, the cabinet lock of the present application includes a lock body 10, a signboard 20, a locking assembly 30, and a handle 40. The lock body 10 has a mounting cavity 11; the signboard 20 has an insertion portion 21, the insertion portion 21 can be inserted into or withdrawn from the installation cavity 11, and the insertion portion 21 has a locking groove 211; the locking assembly 30 is arranged in the installation cavity 11, and the locking pin 31 of the locking assembly 30 can move in the installation cavity 11; the handle 40 is movably connected with the lock body 10, the handle 40 is provided with a sensing piece 41 for driving the locking pin 31 to move towards the handle 40, the lock body 10 is also provided with a locking component, the locking component is provided with a locking state and an unlocking state, wherein when the locking component is in the locking state, the locking component locks the handle 40 at the covering position, and the sensing piece 41 of the handle 40 drives the locking pin 31 to be inserted into the locking groove 211 so as to lock the signboard 20; when the locking component is in the unlocking state, the locking component releases the locking of the handle 40, the handle 40 is switched from the covering position to the opening position, the locking pin 31 is separated from the sensing range of the sensing piece 41, the locking pin 31 exits from the locking groove 211, and the limitation on the signboard 20 is released.

When the cabinet lock with the structure is used, after the insertion part 21 of the signboard 20 extends into the installation cavity 11 to a certain position and the handle 40 is switched from the open position to the closed position, the locking pin 31 of the locking component 30 passes through the locking groove 211 under the action of the sensing piece 41, so that the insertion part 21 is locked, and at the moment, the part of the insertion part 21 extending into the installation cavity 11 cannot exit the installation cavity 11. When the handle 40 is switched from the closed position to the open position, the sensor 41 releases the action on the locking pin 31, so that the locking pin 31 can be withdrawn from the locking groove 211, and the insertion portion 21 can be inserted into or withdrawn from the mounting cavity 11. Therefore, the cabinet lock in this application has solved the inconvenient problem of operation when taking out signboard 20 of cabinet lock among the prior art effectively.

Specifically, the sensing member 41 is a magnetic member having a force to the latching pin 31.

Preferably, in a specific embodiment of the present application, the sensing element 41 is a magnetic steel, and the limit pin 50 can move in the mounting cavity 11 under the magnetic force of the magnetic steel.

Optionally, the handle 40 is pivotally or slidably connected to the lock body 10. In one embodiment of the present application, the handle 40 is pivotally connected to the lock body 10.

Specifically, the lock body 10 has an open structure in communication with the mounting cavity 11, and the handle 40 is capable of covering the open structure and in a covering position. It should be noted that when the latch assembly 30 is in the locked position, the handle 40 covers the open configuration and is in the closed position. When the locking assembly 30 is in the unlocked state, the handle 40 no longer covers the open structure and is switched from the closed position to the open position.

Specifically, the handle 40 is elongated, one end of the handle 40 is a pivoting end connected to the lock body 10, and the sensing element 41 is located on the handle 40. It should be noted that the position of the sensing member 41, the position of the latching groove 211 after the insertion portion 21 is inserted into the mounting cavity 11, and the position of the latching pin 31 are corresponding to each other, or are on the same straight line, so that it can be ensured that the latching pin 31 can pass through the latching groove 211 and lock the insertion portion 21 under the action of the sensing member 41 after the insertion portion 21 is inserted into the mounting cavity 11.

As shown in fig. 1, the insertion portion 21 is a plate shape, and the lock body 10 has an insertion hole 12 through which the insertion portion 21 extends into the mounting cavity 11. The lock body 10 may be formed with an insertion hole 12 at one side wall, or may be formed with an insertion hole 12 at both side walls, so that the insertion portion 21 of the signboard 20 may be inserted into or withdrawn from the installation cavity 11 from the insertion hole 12 at any one side wall of the lock body 10.

Specifically, the cabinet lock further has a handle returning member 60, and the handle returning member 60 is accommodated between the mounting cavity 11 and the handle 40 to provide a returning force for switching the handle 40 from the closed position to the open position. By so arranging, when the locking assembly 30 is switched from the locking state to the unlocking state, it can be ensured that the handle 40 can be more easily switched from the covering position to the opening position by the restoring force of the handle restoring member 60.

In a specific embodiment of the present application, one end of handle resetting piece 60 abuts against the inner wall of mounting cavity 11, the other end of handle resetting piece 60 abuts against handle 40, when handle 40 is in the covering position, handle 40 presses handle resetting piece 60, when handle 40 is switched from the covering position to the opening position, handle 40 moves under the action of handle resetting piece 60, and handle resetting piece 60 is restored from the compressed state to the state before being compressed until handle 40 moves to the opening position.

As shown in fig. 1, the latching assembly 30 further includes a latching release 32, and one end of the latching release 32 abuts against the latching pin 31 to provide the latching pin 31 with a release force to exit the latching groove 211. It should be noted that in the present application, the force applied to the latching pin 31 by the sensing member 41 is greater than the force applied to the latching pin 31 by the unlocking return member 32. Therefore, when the handle 40 is located at the covering position, the latching pin 31 moves toward the sensing member 41 by the sensing member 41 and presses the unlocking restoring member 32, so that the latching pin 31 can pass through the latching groove 211 and lock the portion of the insertion portion 21 protruding into the mounting cavity 11. When the handle 40 is switched from the closed position to the open position, the sensing member 41 no longer acts on the latching pin 31, so that the latching pin 31 can be withdrawn from the latching groove 211 by the unlocking reset member 32 to unlock the insertion portion 21.

As shown in fig. 1, the locking assembly 30 further includes a mounting seat 33, the mounting seat 33 has a mounting groove 331, the locking pin 31 is movably disposed in the mounting groove 331, at least a portion of the locking pin 31 can protrude from the mounting groove 331, and the unlocking reset member 32 abuts between the mounting groove 331 and the locking pin 31. The arrangement can limit the movement direction of the locking pin 31 through the mounting groove 331, so that the locking pin 31 cannot deflect in the movement process, thereby ensuring that the locking pin 31 can pass through the locking groove 211 under the action of the sensing piece 41, and further effectively improving the usability of the cabinet lock.

In one embodiment of the present application, the circumferential side wall of the latching pin 31 further has an annular protrusion, one end of the release and return member 32 abuts against the mounting seat 33, and the other end of the release and return member 32 abuts against the annular protrusion.

In one embodiment of the present application, when locking the signboard 20, the handle 40 is first switched to the open position, the insertion portion 21 can be inserted into the installation cavity 11, after the insertion portion 21 is inserted into the installation cavity, the handle 40 is switched from the open position to the closed position, and the locking pin 31 is inserted into the locking groove 211 to lock the signboard 20. It should be noted that if the handle 40 is switched from the open position to the closed position before the insertion portion 21 is not inserted into the mounting cavity 11, the latching pin 31 is moved to the position of the insertion latching groove 211, so that the insertion portion 21 can not be inserted into the mounting cavity 11 due to the limiting function of the latching pin 31, or even if the insertion portion 21 is inserted into the mounting cavity 11, the insertion portion 21 cannot be inserted into the mounting cavity 11.

In another embodiment of the present application, the side of the latching pin 31 entering toward the insertion part 21 has a guide slope 311, the insertion part 21 presses the guide slope 311, the latching pin 31 moves and exits the insertion track of the insertion part 21, so that the latching pin 31 is inserted into the latching groove 211 after the insertion part 21 is inserted into position. With this arrangement, when the handle 40 is in the covering position and the insertion portion 21 does not extend into the mounting cavity 11, since the locking pin 31 has the guide inclined surface 311 on the side toward the insertion portion 21, the insertion portion 21 can extend into the mounting cavity 11 and press the guide inclined surface 311, so that the locking pin 31 releases the action on the insertion portion 21, and after the insertion portion 21 extends into the mounting cavity 11 to a certain position, the locking groove 211 is aligned with the locking pin 31, so that the locking pin 31 can pass through the locking groove 211 under the action of the sensing member 41 and complete the locking of the signboard 20. Therefore, the problem that the cabinet lock cannot be inserted into the signboard 20 in the locked state in the prior art is effectively solved through the arrangement. However, in this case, the insertion portion 21 can be inserted into the mounting cavity 11 only from the insertion hole 12 facing the guide slope 311.

As shown in fig. 3 and 5, the locking pin 31 further has a limiting groove 312, and the cabinet lock further includes a limiting pin 50, and the limiting pin 50 is inserted into the limiting groove 312 to limit the moving distance of the locking pin 31. Through the arrangement, the locking pin 31 can be prevented from being separated from the mounting seat 33 under the action of the sensing piece 41, so that the usability of the cabinet lock is effectively ensured.

From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects:

1. the problems that the cabinet lock is inconvenient to operate when the signboard is taken out and the signboard cannot be inserted in a locking state in the prior art are effectively solved;
