Abstract
Description
Technical Field
[0001] This utility model relates to the field of locking structure technology, specifically to a smart fingerprint lock locking structure. Background Technology
[0002] A fingerprint lock is an intelligent lock that uses fingerprints as its identification medium. It represents the perfect fusion of computer information technology, electronic technology, mechanical technology, and modern hardware craftsmanship. A fingerprint lock generally consists of two parts: electronic identification and control, and a mechanical linkage system.
[0003] For home users, the fact that fingerprint locks require lubrication is a huge blind spot. Because the lock body itself lacks a lubrication mechanism, and users rarely perform proactive maintenance, its core components are essentially in a state of "dry friction" for extended periods. Every time the door is opened and closed, it exacerbates the wear and tear on the internal metal parts, causing problems to accumulate silently and inevitably manifest as difficulty unlocking or even sudden, complete locking. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows: A smart fingerprint lock locking structure includes a door lock mechanism, a lubrication mechanism, and an oil squeezing mechanism. The door lock mechanism includes a door lock cover and a lock body, with the lock body rotatably extending through the front side of the door lock cover. The lubrication mechanism includes a cross bar located on one side of the lock body, a sleeve that is interference-fitted to the top of the cross bar and fixed to one side wall of the inner side of the door lock cover, and a thin tube connected to and communicating with the sleeve, the outer end of which is in contact with the front side wall of the lock body. The oil squeezing mechanism includes an S-shaped plate that is in contact with the bottom of the cross bar, a gear shaft fixed to the rear side wall of the S-shaped plate, a support plate fixed to the outer edge of the lock body, a lever rotatably mounted on the front side of the support plate and meshing with the gear shaft, and a thin spring fixed between the support plate and the lever.
[0006] By adopting the above technical solution, each time the door is opened, the lock body drives the support plate, lever, and thin spring to rotate clockwise and counterclockwise once. When rotating clockwise, the lever, under the compression of the thin spring, causes the gear shaft and S-shaped plate to rotate one notch. When rotating counterclockwise, the S-shaped plate maintains the angle it has rotated. After multiple door opening actions, when the S-shaped plate rotates to a vertical position, the cross rod pushes into the tube sleeve and forces lubricating oil into the thin tube, which then drips into the lock body. This achieves the purpose of lubrication and effectively reduces the probability of jamming or even locking during the unlocking process.
[0007] In a preferred embodiment, the present invention can be further configured such that: the cross rod is composed of a piston rod and a cross plate, the bottom of the cross plate is fitted with the top of the S-shaped plate, and the cross plate is fixedly sleeved on the outside of the piston rod.
[0008] In a preferred embodiment, the present invention can be further configured such that the lever is located at the bottom of the thin spring, and the front side of the lever is flush with the rear side of the S-shaped plate.
[0009] In a preferred embodiment, the present invention can be further configured such that: a support assembly is provided on the rear side of the gear shaft, the support assembly including a bearing plate fixedly connected to the rear side wall of the gear shaft, two limiting plates rotatably embedded in the top and bottom of the bearing plate and fixedly connected to the front side wall of the door lock cover, and two limiting rods detachably embedded in the rear side of the bearing plate and fixedly connected to the front side wall of the door lock cover.
[0010] In a preferred embodiment, the present invention can be further configured such that: the limiting rod is composed of a metal rod and a rubber ball, the rubber ball is fixedly sleeved on the front end of the metal rod, and the rubber ball extends with interference fit to the rear side wall of the bearing plate.
[0011] In a preferred embodiment, the present invention can be further configured such that: a rod sleeve is provided at the bottom of the horizontal plate, the rod sleeve is movably sleeved on the outside of the piston rod, and is fixedly connected to the front side wall of the door lock cover.
[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, each time the door is opened, the lock body drives the support plate, lever, and thin spring to rotate clockwise and counterclockwise once. When rotating clockwise, the lever, under the compression of the thin spring, causes the gear shaft and S-shaped plate to rotate one notch. When rotating counterclockwise, the S-shaped plate maintains the angle it has rotated. After multiple door opening actions, when the S-shaped plate rotates to a vertical position, the cross rod pushes into the tube sleeve and forces lubricating oil into the thin tube, which then drips into the lock body. This achieves the purpose of lubrication and effectively reduces the probability of jamming or even locking during the unlocking process.
[0013] 2. In this utility model, the cross rod will fall down every time the S-shaped plate rotates 180°, thereby restoring the lubricating oil level in the sleeve and preventing the continuous injection of lubricating oil into the thin tube, effectively reducing the lubricating oil consumption rate and reducing the lubricating oil usage cost.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an intelligent fingerprint lock locking structure. Example 1
[0019] Combination Figure 1-6 As shown, the present invention provides an intelligent fingerprint lock locking structure, including a door lock mechanism 100, a lubrication mechanism 200 and an oil squeezing mechanism 300. The door lock mechanism 100 includes a door lock cover 110 and a lock body 120, and the lock body 120 rotatably passes through the front side of the door lock cover 110. The lubrication mechanism 200 includes a cross bar 210 disposed on one side of the lock body 120, a sleeve 220 that is interference-fitted to the top of the cross bar 210 and fixed to the inner side wall of the door lock cover 110, and a thin tube 230 that is connected and communicates with the sleeve 220. The outer end of the thin tube 230 is in contact with the front side wall of the lock body 120. The oil squeezing mechanism 300 includes an S-shaped plate 310 that is attached to the bottom of the cross bar 210, a gear shaft 320 that is fixed to the rear side wall of the S-shaped plate 310, a support plate 330 that is fixed to the outer edge of the lock body 120, a lever 340 that is rotatably mounted on the front side of the support plate 330 and meshes with the gear shaft 320, and a thin spring 350 that is fixed between the support plate 330 and the lever 340.
[0020] Furthermore, the cross rod 210 is composed of a piston rod 211 and a horizontal plate 212. The bottom of the horizontal plate 212 is attached to the top of the S-shaped plate 310, and the horizontal plate 212 is fixedly sleeved on the outside of the piston rod 211. The structural design of the cross rod 210 enables it to squeeze the lubricating oil in the sleeve 220, providing conditions for the lubricating oil to be injected into the thin tube 230 and even into the lock body 120.
[0021] Furthermore, the lever 340 is located at the bottom of the thin spring 350, and the front side of the lever 340 is flush with the rear side of the S-shaped plate 310. The layout design of the lever 340 ensures that it will not affect the rotation of the S-shaped plate 310. Example 2
[0022] Combination Figure 1 , 2 5 and Figure 6 As shown, based on Embodiment 1, a support assembly 400 is provided on the rear side of the gear shaft 320. The support assembly 400 includes a bearing plate 410 fixedly connected to the rear side wall of the gear shaft 320, two limiting plates 420 rotatably embedded in the top and bottom of the bearing plate 410 and fixedly connected to the front side wall of the door lock cover 110, and two limiting rods 430 detachably embedded in the rear side of the bearing plate 410 and fixedly connected to the front side wall of the door lock cover 110. The bearing plate 410 and the limiting plates 420 cooperate to enable the gear shaft 320 to stably drive the S-shaped plate 310 to rotate, thereby improving the overall structural stability of the device. The limiting rods 430 prevent the S-shaped plate 310 from rotating in the opposite direction.
[0023] Specifically, the limiting rod 430 is composed of a metal rod and a rubber ball. The rubber ball is fixedly sleeved on the front end of the metal rod and extends with interference fit to the rear side wall of the bearing plate 410. The structural design of the limiting rod 430 enables it to stably restrict the rotation of the bearing plate 410. Example 3
[0024] Combination Figure 1 , 2 4 and Figure 5 As shown, in the above embodiment, the bottom of the horizontal plate 212 is provided with a rod sleeve 500. The rod sleeve 500 is movably sleeved on the outside of the piston rod 211 and fixed to the front side wall of the door lock cover 110. The rod sleeve 500 can guide the cross rod 210 and improve the lifting stability.
[0025] Working principle and usage process of this utility model: When this device is put into actual use, the lock body 120 will drive the support plate 330 to rotate clockwise and counterclockwise once each time the door is opened.
[0026] During this process: Clockwise rotation phase: Under the compression of the thin spring 350, the lever 340 rotates clockwise and drives the gear shaft 320 and S-shaped plate 310 to rotate by a predetermined angle. Counterclockwise reset phase: When the support plate 330 returns to its counterclockwise position, the lever 340 resets accordingly and loses its driving constraint on the gear shaft 320. At the same time, since the bearing plate 410 connected to the gear shaft 320 is restricted by the limit rod 430, the gear shaft 320 and the S-shaped plate 310 are prevented from rotating in the opposite direction, thereby maintaining the already rotated angle.
[0027] After repeated opening actions, the S-shaped plate 310 rotates continuously in one direction until it is in a vertical position. At this position, the cross bar 210 is pushed into the sleeve 220. The lubricating oil pre-stored in the sleeve 220 is then precisely injected into the lock body 120 through the thin tube 230 under pressure, realizing a periodic and automatic lubrication function. This design can effectively reduce the risk of jamming or even locking during the unlocking process and improve the long-term operational reliability of the lock.
[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
