In this embodiment, the mounting seat 1 is integrally cast, so that the structural strength of the mounting seat 1 is higher.

[0030] The working principle of this embodiment:

[0031] When the cabinet does not need to be protected from theft or the cabinet door does not need to be temporarily closed in a short period of time, the user first switches the locking structure 45 to the unlocked state by using the key, and then the key can be deposited. After that, the user only needs to press the release button 43 to unlock the cabinet lock, so that the cabinet lock can be used by keyless users. It is more convenient to use in scenarios where there are many users and the cabinet does not need to be protected from theft or the cabinet door does not need to be temporarily closed in a short period of time. When the cabinet needs to be protected from theft, the locking structure 45 is switched to the locked state by using the key, and the release button 43 is locked by the locking structure 45 and cannot be pressed, so that the keyless user cannot unlock the cabinet lock.

In this embodiment, the locking elastic member 42 is a tension spring, one end of the locking elastic member 42 is connected to the mounting seat 1, and the other end of the locking elastic member 42 is connected to the fastening portion 411.

[0033] like Figure 5 , Figure 6 and Figure 7 As shown, a limiting structure 11 is formed on the mounting seat 1. The limiting structure 11 is a limiting hole for the fastening portion 411 of the fastening piece 41 to pass through. The limiting structure 11 is used to limit the range of motion of the fastening portion 411 of the fastening piece 41 in the forward rotation. The hook head 4111 of the fastening piece 41 is also formed with an extrusion slope 4112. When the cabinet lock switches from the unlocked state to the locked state, the extrusion slope 4112 can be squeezed by the handle 2 to drive the fastening piece 41 to rotate in the reverse direction. With such a design, when the handle 2 is locked, there is no need to perform an additional operation of giving way to the fastening piece 41, which is more convenient to use.

[0034] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the release button 43 includes a button body 431, a pressing portion 432 and a locking portion 433. The button body 431 is a cylindrical structure, one end of the button body 431 is an operating end, and the other end of the button body 431 is a pressing end. A mounting groove 4311 is formed on the end surface of the pressing end of the button body 431, and the button body 431 can be slidably mounted on the mounting seat 1; the reset elastic member 44 is a compression spring, and the reset elastic member 44 is compressed and arranged in the mounting groove 4311 of the button body 431 and the mounting seat 1; one end of each of the pressing portion 432 and the locking portion 433 is connected to the circumferential surface of the button body 431, and the other end of each of the pressing portion 432 and the locking portion 433 is extended along the axis of the button body 431 and protrudes from the pressing end surface of the button body 431; the pressing portion 432 can be driven by the positively sliding button body 431 to squeeze the unfastening portion 412 of the fastening member 41; the locking portion 433 can be blocked by the locking structure 45 in the locked state to prevent the button body 431 from sliding forward. In this embodiment, the pressing portion 432 and the locking portion 433 are respectively arranged on opposite sides of the button body 431, and the length of the pressing end of the pressing portion 432 protruding from the button body 431 is greater than the length of the pressing end of the locking portion 433 protruding from the button body 431; by setting the design of the pressing portion 432 and the locking portion 433, the length dimension of the button body 431 can be reduced, and the production cost can be reduced.

[0035] like Figure 7 As shown, the mounting seat 1 is also formed with a first positioning slideway and a second positioning slideway, the pressing portion 432 of the release button 43 is slidably embedded in the first positioning slideway, the locking portion 433 of the release button 43 is slidably embedded in the second positioning slideway, and the sliding directions of the pressing portion 432, the locking portion 433, and the button body 431 of the release button 43 are parallel, so that the release button 43 is positioned in the circumferential direction. In the process of using the release button 43, such a design can prevent the positions of the pressing portion 432 and the locking portion 433 from being offset and affecting the normal operation of the locking mechanism 4.

[0036] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the locking structure 45 includes a lock core 451 and a locking paddle 452. The locking paddle 452 is rotatably mounted on the mounting base 1. The locking paddle 452 can be switched between a locked state and an unlocked state by rotating. The locking paddle 452 in the locked state can block the locking portion 433 of the release button 43 to prevent the release button 43 from sliding forward. The lock core 451 is mounted on the mounting base 1. The movable portion of the lock core 451 is connected to the locking paddle 452, so that the movable portion of the lock core 451 can be rotated by a key to drive the locking paddle 452 to rotate. This design can make the connection structure between the locking structure 45 and the release button 43 simpler and more compact, reducing the production cost.

[0037] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the present embodiment also includes an anti-disassembly plate 5, on which four fixing holes 51 connecting the two side surfaces are formed, and the four fixing holes 51 are arranged in a rectangular array on the anti-disassembly plate 5; four fixing protrusions 13 are formed on the mounting seat 1, and a fixing protrusion 13 is connected to a fixing hole 51 by reverse riveting, so that the mounting seat 1 and the anti-disassembly plate 5 are enclosed to form a mounting cavity; the locking elastic member 42, the release button 43, the reset elastic member 44, the lock core 451 and the locking paddle 452 of the locking mechanism 4 are all arranged in the mounting cavity, and when the cabinet lock is in a locked state: the distance D1 between the locking paddle 452 and the anti-disassembly plate 5 is smaller than the distance D2 between the release button 43 and the fastening member 41. When a large force is applied to the release button 43, such as using a hammer or other tool to hit the release button 43 from the outside of the mounting base 1, the locking paddle 452 may be displaced due to the squeezing of the release button 43, resulting in the locking paddle 452 being unable to prevent the release button 43 from sliding forward, so that the release button 43 can drive the locking paddle 452 to continue to slide forward and press the fastening member 41, so that the cabinet lock can be unlocked by force. By adding the design of the anti-disassembly plate 5, the movable range of the locking paddle 452 driven to slide by the release button 43 can be limited, and the four fixing holes 51 of the anti-disassembly plate 5 are connected to the mounting base 1 by reverse riveting, so that the connection structure between the anti-disassembly plate 5 and the mounting base 1 is very stable, thereby preventing the cabinet lock in a locked state from being unlocked by force, thereby improving the safety of the cabinet lock.

[0038] In this embodiment, two installation folds 52 are formed on the anti-disassembly plate 5 by bending in the direction away from the mounting seat 1. The buckle 41 is rotatably mounted between the two installation folds 52. A clearance opening 53 connecting the two sides of the anti-disassembly plate 5 is formed. The clearance opening 53 is located between the two installation folds 52 to provide a rotation space for the buckle 41. A reinforcement hole 54 is also formed on the anti-disassembly plate 5. The reinforcement hole 54 is located on one side of the clearance opening 53. The four fixing holes 51 are located on the other side of the clearance opening 53. A reinforcement convex portion 14 is formed on the mounting seat 1. The reinforcement convex portion 14 is connected to the reinforcement hole 54 by reverse riveting. The end of the locking elastic member 42 that is not connected to the buckle 41 is mounted on the anti-disassembly plate 5, and the end of the reset elastic member 44 that is not connected to the release button 43 is mounted on the anti-disassembly plate 5. Such a design makes the structure of the cabinet lock more compact, the force structure between the anti-disassembly plate 5 and the mounting seat 1 more reasonable, and the connection structure between the anti-disassembly plate 5 and the mounting seat 1 more stable.
