Description

Technical Field

[0001] This utility model belongs to the field of fingerprint lock technology, specifically relating to a modularly assembled fingerprint lock structure. Background Technology

[0002] A fingerprint lock is an intelligent lock that uses human fingerprints as the identification medium and method. Traditional fingerprint locks are installed on the lock body panel by screws and include a handle body, a cover plate, and a fingerprint button module, as shown in CN202021610714.1. During assembly, the fingerprint button module is attached to the cover plate of the handle body, and then the screw passes through the cover plate from the inside of the door and is fixed to the handle body with the fingerprint button module. Because the fingerprint button module needs to be manually pressed when it is attached to the cover plate during installation, and then the screw is tightened, it is not only inconvenient to disassemble and assemble, but the fingerprint button module may also shift relative to the cover plate when the screw is tightened, which will affect the stability of the assembly and the efficiency of the installation. Therefore, its applicability is difficult to meet the needs of the market. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] See Figures 1 to 4 As shown, a modular fingerprint lock structure includes an electronic lock front panel 1, a locking screw 2, and a fingerprint lock module 3. The front of the electronic lock front panel has a fingerprint lock mounting chamber 4, and the bottom wall of the fingerprint lock mounting chamber has a connection terminal 5 and at least one locking protrusion 6. The bottom edge of the fingerprint lock module has a mounting terminal 18 and a locking slot 7 that mates with the locking protrusion. Its connection terminal is connected to the circuit board inside the electronic lock front panel to ensure the effectiveness of data transmission and electrical connection. This is a conventional structure in the prior art. The locking protrusion and locking slot can ensure the stability and reliability of the fingerprint lock module installation during maintenance.

[0030] During use, the fingerprint lock module is inserted into the fingerprint lock mounting cavity, and the locking protrusion is locked into the locking slot for limitation. The locking screw passes through the front panel of the electronic lock and is threadedly connected and fixed to the inner side of the fingerprint lock module. This, combined with the locking screw, ensures a stable and reliable connection.

[0031] In this embodiment, a locking nut that mates with a locking screw is embedded within the fingerprint lock module; and the locking screw is threadedly connected to the locking nut. The position of the locking nut is fixed, ensuring the stability and reliability of the connection with the locking nut.

[0032] In this embodiment, the front panel of the electronic lock is provided with a mounting through hole 8; the front panel of the electronic lock is provided with a limiting through hole 9, and a magnet 10 is embedded on the mating surface of the fingerprint lock module; a guide cylinder 11 with its bottom closed is provided in the limiting through hole, and the guide cylinder is fixed to the front panel of the electronic lock by screws; a lifting column 12 is provided in the guide cylinder, and a magnetic block 13 is fixed to the top of the lifting column; a spring 14 is provided between the lifting column and the bottom wall of the guide cylinder; the spring is mainly used for the lifting column to rise and fall in the guide cylinder. In use, the fingerprint lock module is mated to the outer side of the front panel of the electronic lock, and the magnetic block and the magnet are magnetically attracted and limited; the locking screw passes through the mounting through hole and is threaded onto the locking nut. During maintenance, the fingerprint lock module is initially positioned using magnets and magnetic blocks, eliminating the need for additional force. Then, a locking screw is installed from the inside of the front panel of the electronic lock, which improves the ease of installation and facilitates the threaded connection between the locking screw and the fingerprint lock module, enhancing installation reliability, reducing the installation difficulty of the fingerprint lock module, and making it highly adaptable.

[0033] In this embodiment, using the above structure, when the lifting column is magnetically attracted to the magnet and the magnetic block, the spring will be stretched. When the fingerprint lock module is magnetically attracted, the external force disappears, and under the reset action of the spring, the fingerprint lock module is attracted to the upper limit of the outer side of the front panel of the electronic lock.

[0034] The inner wall of the guide cylinder is provided with a guide strip 15; the bottom end of the lifting column is integrally formed with a protruding ring 16, and the edge of the protruding ring is provided with a guide groove 17 that cooperates with the guide strip. Through the above structure, the lifting column can be raised and lowered smoothly, and the magnetic attraction operation of the fingerprint lock module magnet can be completed within a certain distance range.

[0035] The magnetic block is a screw, which is threaded and fixed to the end of the lifting column. The height of the limiting cylinder is matched with the thickness of the front panel of the electronic lock.

[0036] The structure of this utility model is reasonable. The fingerprint lock module is inserted into the fingerprint lock installation cavity, and the locking protrusion is locked into the locking slot hole for limitation. The locking screw passes through the front panel of the electronic lock and is threadedly connected and fixed to the inner side of the fingerprint lock module. Through the above structure, modular disassembly and assembly for maintenance of the smart lock can be realized, which helps to reduce the difficulty of maintenance and improve the effectiveness and convenience of maintenance. Moreover, locking and positioning by locking screw also helps to improve the stability and reliability of the connection.

[0037] Meanwhile, in this embodiment, a guide column is provided on the front panel of the electronic lock, and a lifting column and a spring are provided inside the guide column. A magnetic block is provided on the lifting column, and a magnet is embedded in the fingerprint lock module. When the fingerprint lock module is installed, it is initially limited by magnetic attraction through the magnetic block and the magnet, and then the locking screw is installed from the inside of the front panel of the electronic lock. It is not necessary to stabilize the fingerprint lock module separately, which helps to improve the convenience of disassembly and assembly. Furthermore, when installing the locking screw, it can also prevent the fingerprint lock module from shaking or shifting, thereby improving the installation accuracy and stability, and making it highly applicable.

[0038] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
