Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a lock with a wiring protection function. Background Art

[0002] Some existing smart door locks are equipped with a fingerprint head module on the handle of the lock. Then, a cable is required to enter the handle inside the lock to electrically connect the fingerprint head module with the circuit board. When the user usually uses the smart door lock, he unlocks the door by turning the handle to drive the square bar on the lock body inside the door. In the existing smart locks of this type, when the user drives the handle to rotate, the cable will be driven to swing with the handle to a large extent. Over time, the cable will be easily worn out, resulting in disconnection and fingerprint head failure. Among them, it is inevitable that the cable swings because the handle is rotated when the door is actually opened. However, most users are used to turning the handle after closing the door to see if the door is locked and cannot be opened. Some people who cannot unlock the door with fingerprints will also turn the handle in front of the door to try to open the door. Therefore, these handle rotation actions that are not actually able to open the door will greatly increase the frequency of large swings of the cable, thereby causing wear and damage to the cable. In view of this, the present application makes improvements. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the attached embodiment of the utility model Figure 1-9 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] like Figures 1 to 9 As shown, the utility model discloses a lock with a wiring protection function, including a panel 1, a handle 2 is rotatably connected to the panel 1, a fingerprint head module 3 is provided on the handle 2, a front clutch 4 fixedly connected to the handle 2 is provided inside the panel 1, that is, on the rear side of the panel 1, and a rear clutch 5 is rotatably connected to the front clutch 4, a connecting seat 51 is integrally formed on the rear side of the rear clutch 5, a square bar socket 52 is opened on the connecting seat 51, and the square bar socket 52 is subsequently used for inserting the square bar on the lock body in the door, wherein a locking rod 66 is provided on the lower side of the rear clutch 5, and a driving mechanism for pushing the locking rod 66 to insert into the front clutch 4 is provided in the panel 1, in addition, a wiring entry port 53 located in front of the connecting seat 51 is opened on the upper side of the rear clutch 5, and the rear clutch 5 is also provided with a wiring guide frame 54 at the position of the wiring entry port 53.

[0028] When the flat cable 9 is connected from the circuit board 8 to the fingerprint head module 3 in the handle 2, Fig. 9 As shown, the cable 9 enters the cable entry port 53 on the rear clutch 5 through the cable guide frame 54 on the rear clutch 5, passes through the rear clutch 5 and the front clutch 4, enters the handle 2 and is electrically connected to the fingerprint head module 3. In the utility model, when the user simply rotates the handle 2, the handle 2 rotates to drive the front clutch 4 to rotate. Since the rear clutch 5 is rotationally matched with the front clutch 4, the friction between the front clutch 4 and the rear clutch 5 is insufficient to drive the rear clutch 5 to rotate with the square bar on the lock body, so the door cannot be opened, and the rear clutch 5 will not rotate either. Therefore, it is avoided that the cable 9 makes a large swinging movement with the rotation of the rear clutch 5. After the user performs fingerprint recognition through the fingerprint head module 3, the driving mechanism pushes the lock rod 66 to insert the front clutch 4. At this time, when the handle 2 rotates, the front clutch 4 can drive the rear clutch 5 to rotate together, and the rear clutch 5 drives the square bar on the lock body to rotate, so that the lock body is unlocked, and the user can open the door. In summary, the utility model can prevent the cable 9 from following the handle 2 to perform a large swinging motion when the handle 2 is not actually capable of opening the door, thereby effectively reducing the wear and damage of the cable 9 and effectively protecting the cable 9.

[0029] The specific structure of the front clutch 4 fixed on the handle 2 is as follows: Figure 8 As shown, a connection socket 21 is provided on the handle 2, and a wire port 22 leading to the fingerprint head module 3 is provided on one side of the connection socket 21. Figures 5 to 7As shown, a connecting plug 41 is provided on the front clutch 4 and inserted into the connecting socket 21, and a line outlet 42 corresponding to the line passing port 22 is opened on the side wall of the connecting plug 41, wherein the cable 9 enters the cable entry port 53 on the rear clutch 5, enters the connecting plug 41 of the front clutch 4 and passes through the line outlet 42 and the line passing port 22 to reach the position of the fingerprint head module 3 and is electrically connected to the fingerprint head module 3.

[0030] Furthermore, in order to improve the connection strength between the front clutch 4 and the handle 2, a screw 43 is provided inside the connecting tube 41, and a threaded hole 23 for threading the screw 43 is provided on the handle 2.

[0031] The specific structure of the rear clutch 5 rotatingly engaging with the front clutch 4 is as follows: Figure 7 As shown, a matching sleeve 44 is integrally formed at the rear end of the front clutch 4 , and the front clutch 4 is rotatably matched on the matching sleeve 44 .

[0032] In addition, a locking rod socket 45 for inserting the locking rod 66 is radially opened on the side wall of the matching sleeve 44, and two locking rod sockets 45 are symmetrically opened on the matching sleeve 44. This is to facilitate the matching sleeve 44 to change the direction of the handle 2 when the user adjusts and changes the rotation unlocking direction.

[0033] The specific structure of the lock rod 66 disposed on the rear clutch 5 is as follows: Figure 4 As shown, an assembly groove 55 is provided on the rear clutch 5, and the locking rod 66 is slidably fitted in the assembly groove 55. A supporting ring 61 is also provided on the locking rod 66, and a spring 62 for pushing the locking rod 66 away from the locking rod socket 45 is provided in the assembly groove 55. In this way, in a natural state, the locking rod 66 will not enter the locking rod socket 45, and can only enter the locking rod socket 45 when the driving mechanism pushes the locking rod 66.

[0034] The driving mechanism specifically includes an arc-shaped push plate 71 and an electric cylinder 72. The arc-shaped push plate 71 is located at the lower side of the lock rod 66. The electric cylinder 72 is fixed in the panel 1. The output shaft on the electric cylinder 72 is connected to the arc-shaped push plate 71. The electric cylinder 72 can push the arc-shaped push plate 71, so that the arc-shaped push plate 71 pushes the lock rod 66 into the lock rod socket 45, so that the rear clutch 5 and the front clutch 4 cannot rotate relative to each other. At this time, when the handle 2 rotates, the front clutch 4 can drive the rear clutch 5 to rotate together, thereby driving the square bar inserted in the square bar socket 52 to rotate, so that the lock body in the door is unlocked.

[0035] In the present invention, the panel 1 is fixedly connected with a cable guide post 11 located on the upper side of the cable guide frame 54, and two cable guide posts 11 are symmetrically arranged, which is also for the convenience of the handle 2 when the user adjusts and changes the rotation unlocking direction to cooperate with the sleeve 44. Fig. 9As shown, because at this time the handle 2 drives the front clutch 4 and the rear clutch 5 to rotate clockwise to unlock, that is, to rotate in the direction of the cable guide column 11 that the cable 9 bypasses, the cable 9 must bypass the cable guide column 11 on the right side, so that when the rear clutch 5 rotates, it can prevent the cable 9 from being pulled. The setting of the cable guide column 11 can enable the cable 9 to enter the cable guide frame 54 from the circuit board 8 in an orderly manner, and is also beneficial to reduce the swing amplitude of the cable 9 when the rear clutch 5 rotates, which is beneficial to protect the cable 9.

[0036] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
