Technical Field

[0001] This utility model relates to the field of fingerprint locks, and in particular to a fingerprint lock that is easy to install. Background Technology

[0002] A fingerprint lock is a smart lock that uses human fingerprints as identification credentials. It is a perfect combination of computer information technology, electronic technology, mechanical technology, and modern hardware craftsmanship. A fingerprint lock consists of two panels, an inner and an outer panel, located on opposite sides of the door. The battery is located in the inner panel, providing the necessary power. The fingerprint recognition area is located on the outer panel. Users simply place their finger on the fingerprint recognition area to quickly unlock the door, eliminating the need to carry keys and avoiding the inconvenience of lost, stolen, or forgotten keys. Fingerprint locks are widely used in homes, offices, hotels, and other places, providing a safer and more convenient access control solution for people's lives and work.

[0003] Currently, fingerprint locks typically use a square rod inserted into a square hole in the lock body for mechanical linkage between the front and rear locks. The length of this connecting rod is usually fixed. However, due to the varying thicknesses of door panels across different brands, a certain length is usually reserved during manufacturing to ensure a proper connection between the front and rear panels when installing a fingerprint lock on a thicker door panel. On thinner door panels, the connecting rod needs to be cut according to the actual thickness, a time-consuming process that can reduce installation efficiency. Furthermore, the front and rear panels are usually secured to the sides of the door panel with screws and spring washers to prevent loosening, making the installation process somewhat complicated and potentially damaging to the door panel.

[0004] Therefore, those skilled in the art have provided a fingerprint lock that is easy to install in order to solve the problems mentioned in the background art. Utility Model Content

The inner wall of the slot 204 is flush with the small-sized snap-fit ​​block 306. The outer surfaces fit tightly together, and the small locking block 306 can only move up and down when a certain external force is applied. When no external force is applied, the locking groove 204 and the small locking block 306 are in a stable locking state. The movable cavity 205 allows the control block 207 and the triangular block 208 to move. The control block 207 can slide up and down. The spring telescopic rod 206 supports the control block 207.

When the control block 207 moves down, it applies downward pressure to the triangular blocks 208. The triangular blocks 208 and the sliding block 202 are rotatably connected by a spring clip. When the triangular blocks 208 are not subjected to external force, the spring force of the spring clip will cause them to retract inside the movable cavity 205.

[0040] Reference Figure 2 , Figure 3 , Figure 7 The rear component 3 includes a rear panel 301. A large card holder 305 is fixedly connected to the front end of the rear panel 301 near the upper end, and a small card holder 306 is fixedly provided at the lower end of the large card holder 305.

[0041] The rear panel 301 is located at the rear end of the door panel 401. The rear handle 302 is rotatably sleeved near the middle of the rear end of the rear panel 301. The battery slot 303 is opened near the upper end of the rear end of the rear panel 301. The movable plate 304 is slidably arranged near the upper end of the rear end of the rear panel 301. The large snap-fit ​​block 305 is slidably arranged in the groove 203, and the small snap-fit ​​block 306 is slidably arranged in the slot 204.

[0042] Specifically, the rear panel 301 is located inside the door panel 401, the rear handle 302 has the same function as the front handle 102, the battery slot 303 is used to store batteries, and the movable plate 304 controls the opening and closing of the battery slot 303. When the large locking block 305 and the small locking block 306 are respectively locked into the groove 203 and the slot 204, the connection between the adjustment component 2 and the rear component 3 can be realized.

[0043] Reference Figure 4 , Figure 6 , Figure 7The door assembly 4 includes a door panel 401. A square groove 402 is provided at the front end of the door panel 401. Limiting grooves 403 are provided on both sides of the inner surface of the square groove 402 near the rear end.

[0044] Specifically, the door panel 401 is the main body on which the fingerprint lock needs to be installed. The inner wall of the square groove 402 has the same dimensions as the outer surface dimensions of the fixed block 105 and the sliding block 202. The fixed block 105 and the sliding block 202 can slide smoothly in it. The square groove 402 can prevent the connecting rod from rotating, thereby ensuring the upright position of the fingerprint lock body. The limiting groove 403 can engage with the triangular block 208 to lock the position of the sliding block 202 and ensure the stability after the length of the connecting rod is adjusted.

[0045] Working principle: When the fingerprint lock needs to be installed, the fixed rod 104, fixed block 105, sliding rod 201 and sliding block 202 form a connecting square rod. Slide the sliding block 202 backward to maximize the length of the entire connecting square rod. Align the connecting square rod with the square groove 402 and move the front panel 101 backward to control the electric telescopic block to extend and engage in the square groove 402. Then, align the large locking block 305 on the rear panel 301 with the groove 203. Place the large locking block 305 and the small locking block 306 tightly against the groove 203 and slide them slightly downward so that the lower end of the small locking block 306 engages in the slot 204. However, no pressure is applied to the control block 207, thus connecting the sliding block 202 with the rear panel 301 and ensuring the synchronous movement of the sliding block 202 and the rear panel 301.

[0046] Then, the rear panel 301 is moved forward so that its front end is flush with the rear end face of the door panel 401. At this point, the length of the connecting rod matches the thickness of the door panel 401, and the two sides of the movable cavity 205 are aligned with the two limiting grooves 403. Next, the rear panel 301 is moved downward, causing the small locking block 306 to continue moving downward. During this movement, the small locking block 306 applies downward pressure to the control block 207, causing the control block 207 to move downward along the inner wall of the movable cavity 205. The spring telescopic rod 206 retracts accordingly. As the control block 207 moves downward, its lower ends can push the two triangular blocks 208 to flip to both sides. The mechanism allows a portion of each of the two triangular blocks 208 to slide from the movable cavity 205 into the limiting groove 403. The two triangular blocks 208 are respectively engaged with the two limiting grooves 403. The limiting effect of the limiting grooves 403 can lock the sliding block 202, stabilizing the connecting rod at a suitable length. At the same time, the front panel 101 is installed through the engagement of the electric telescopic block. The rear panel 301 is connected to the sliding block 202 through the engagement of the small engagement block 306. The sliding block 202 is connected to the door panel 401 through the engagement of the triangular blocks 208, thus realizing the installation of the rear panel 301. This enables the installation of the fingerprint lock.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
