Example 1:

Referring to fig. 1-9, the present embodiment provides a detachable fingerprint lock, which includes a first lock housing 100, a second lock housing 200, and a lock cylinder 300;

The first lock case 100 is generally used for being mounted on a storage box body, the first lock case 100 is provided with a lock case bottom plate 110 and a lock case cover plate 120, the lock case bottom plate 110 is detachably connected with the lock case cover plate 120, and a mounting cavity is formed between the lock case bottom plate 110 and the lock case cover plate 120 and provides a space for mounting the lock cylinder 300; a first through hole 111 is formed on one side of the lock case bottom plate 110, and a second through hole 121 is formed on the lock case cover plate 120;

The second lock case 200 is generally used for being mounted on the storage box cover, the second lock case 200 is provided with a lock pin 210 which can be inserted into the first through hole 111, and a lock groove 211 is formed on the side surface of the lock pin 210;

The lock cylinder 300 is installed in the installation cavity, and the lock cylinder 300 comprises a driving component 310, a lock tongue 320, an installation plate 410 and a fingerprint identification module 330; the driving component 310 and the lock tongue 320 are arranged in the mounting cavity, and the driving component 310 is linked with the lock tongue 320; the lock tongue 320 is disposed near the first through hole 111, and the lock tongue 320 has a locking end 321 that can be inserted into the locking groove 211; the fingerprint recognition module 330 is fixed on a mounting plate 410, and the mounting plate 410 covers the second through hole 121; the fingerprint identification module 330 is electrically connected with the driving component 310;

when in use, a correct fingerprint is input to the fingerprint identification module 330, so that the fingerprint identification module 330 controls the driving component 310 to drive the lock tongue 320 to be close to or far away from the first through hole 111, thereby enabling the lock end 321 to be inserted into or withdrawn from the lock groove 211, and realizing the locking or unlocking of the first lock case 100 driving the box body and the second lock case 200 driving the box cover.

The detachable fingerprint lock of the embodiment is provided with the first lock shell 100 and the second lock shell 200, wherein an installation cavity is formed in the first lock shell 100 and a lock cylinder 300 is installed; the first lock case 100 is used for being mounted on a storage box body, the second lock case 200 is used for being mounted on a storage box cover, the box cover is covered on the box body, so that the lock pin 210 of the second lock case 200 is inserted into the first through hole 111 on the second lock case 200, and the lock tongue 320 extends to insert the lock end 321 into the lock groove 211 to clamp the lock end, thereby realizing the locking of the storage box. When unlocking, a correct fingerprint is input to the fingerprint identification module 330, and after identification is successful, the driving component 310 drives the lock tongue 320 to move in a direction away from the first through hole 111, so that the lock end 321 is away from the lock groove 211, and the lock is unlocked; the key is not required to be independently equipped or found, and the use is convenient and quick. Through setting up second through-hole 121 to with fingerprint identification module 330 through mounting panel 410 lid in second through-hole 121, only need expose mounting panel 410 part and box body surface during the installation, fingerprint lock occupation space is little, satisfies the receiver to the requirement of box body surface aesthetic property. By opening the mounting plate 410 covered on the second through hole 121, the parts in the mounting cavity can be replaced and maintained, and when the fault occurs, the parts such as the battery can be replaced only by opening the mounting plate 410, so that the box body or the lock catch is not required to be damaged, and the practicability is high.

In some embodiments, the mounting plate 410 may be covered on the second through hole 121 by a manner of a buckle, which has the advantages of simple disassembly, but has the problem of poor connection strength and stability, and in order to overcome the problem, the mounting plate 410 and the second through hole 121 are fixed by a threaded connection manner; however, since the fingerprint recognition module 330 on the mounting board 410 needs to be connected with the driving assembly 310 through wires, the mounting board 410 can drive the wires to twist and wind during rotation, which results in a risk of line failure. 7-8, the detachable fingerprint lock of the present embodiment is provided with a fixing ring 420 circumferentially sleeved on the mounting plate 410, and the fixing ring 420 can rotate along the axis of the fixing ring relative to the mounting plate 410; specifically, the mounting plate 410 is circumferentially formed with an annular groove, and the fixing ring 420 is disposed in the annular groove so that the fixing ring 420 can rotate with respect to the mounting plate 410; the fixing ring 420 is screwed with the lock case cover 120.

Further, a first limiting member 411 is disposed on a side of the mounting plate 410 near the lock housing bottom plate 110, the first limiting member 411 in this embodiment is a clamping block, a second limiting member 112 is disposed at a corresponding position of the lock housing bottom plate 110, and the second limiting member 112 in this embodiment is a clamping groove adapted to the clamping block; by clamping the clamping block into the clamping groove, the mounting plate 410 is positioned, so that the fingerprint identification module 330 is fixed at a correct angle, and the rotation of the mounting plate 410 relative to the lock case bottom plate 110 is limited.

The periphery of the fixed ring 420 is circumferentially provided with a first anti-slip part 421; thereby increasing friction force and facilitating the loading and unloading of the fixing ring 420. In order to make the surface of the storage box more attractive, the volume of the fingerprint lock exposed on the surface of the box body is always smaller, and the too small force application point is not beneficial to the assembly and disassembly of the fixed ring 420, based on the fact, the fingerprint lock of the embodiment is further provided with a force-aid ring 430, the inner side of the force-aid ring 430 is provided with a second anti-slip part 431 matched with the first anti-slip part 421, the force-aid ring 430 is sleeved on the outer side of the fixed ring 420, the first anti-slip part 421 is clamped with the second anti-slip part 431, and when the fingerprint lock is used, the torque of the force-aid ring 430 is transmitted to the fixed ring 420 to enable the mounting plate 410 to be screwed or unscrewed, and after the assembly and disassembly steps are completed, the force-aid ring 430 can be disassembled, so that the attractive surface of the storage box is maintained.
