DETAILED DESCRIPTION

[0026] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] Refer to Figures 1-9As shown, the utility model provides a fingerprint lock with protective treatment, including a cylindrical shell 1, the outer wall of the cylindrical shell 1 is provided with a fingerprint panel 2, and the outer end surface of the cylindrical shell 1 is provided with a password panel 3, which can be unlocked and opened by fingerprint or password. A lock body structure clutch is provided in the cylindrical shell 1, and is electrically connected to the fingerprint panel 2 and the password panel 3 (the lock body structure belongs to the prior art and will not be elaborated here). The focus is on the protection of the fingerprint panel 2 and the password panel 3, specifically involving a circular smart lock. Because the prior art smart locks often have rectangular frames, a sliding cover is provided to erase the fingerprints remaining on the fingerprint panel 2 and the password panel 3 to prevent unauthorized elements from collecting fingerprints or passwords, which may cause danger to people and property. However, circular smart locks currently have few protective treatments on the panel and the sliding cover type is not applicable. Therefore, this application also includes a first protective member 4 and a second protective member 5. The first protective member 4 is connected to the outer wall of the cylindrical shell 1. The first protective member 4 is used to protect the fingerprint panel 2. The second protective member 5 is detachably connected to the outer end face of the cylindrical shell 1. It can be achieved by threaded connection, socket connection, snap connection, etc. The second protective member 5 is used to protect the password panel 3. The protective members are set according to the actual situation of the circular smart lock. This application takes the fingerprint panel 2 as an example and the password panel 3 as an example. It is also possible that the fingerprint and password are both set on the outer end face or the outer wall of the cylindrical shell 1. Therefore, only one protective member can be set.

[0028] Refer to Figure 4 、 Figure 5 As shown, the first protective member 4 and the second protective member 5 are both provided with a cleaning layer 17, which is used to erase residual fingerprints on the password panel 3 and the fingerprint panel 2. The cleaning layer 17 is a cleaning sponge or a cleaning cloth, which is fixed to the first protective member 4 and the second protective member 5 by Velcro or snap connection.

[0029] Refer to Figure 1-Figure 4As shown, the outer wall of the cylindrical shell 1 is provided with guide grooves 11 on both sides corresponding to the fingerprint panel 2, and a first spring 12 is provided in the guide groove 5411, and a limiting groove 13 is extended on both sides of the guide groove 11. The first protective member 4 includes an arc-shaped plate, and the arc-shaped plate is provided with a guide block 42 corresponding to the guide groove 11, and the guide block 42 abuts on the first spring 12.

A V-shaped hinged rod is connected between the blocks, and a rotating rod 8 is connected to the hinged end of the V-shaped hinged rod. The rotating rod 8 is threadedly connected to the convex channel. The outer end of the rotating rod 8 is provided with a cross slot, and the arc plate is provided with an opening corresponding to the convex channel. When the first protective member 4 needs to be removed, an external screwdriver is inserted into the cross slot to rotate the rotating rod 8, so that the movable block is recovered and then disengaged from the limiting groove 13, so that the arc plate and the guide block 42 are removed from the guide slide 11, which is convenient for replacing parts or cleaning the layer 17 or repairing the fingerprint panel 2 or other problems. The arc plate is different from the cylindrical shell 1 in that the end of the arc plate near the fingerprint panel 2 extends upward and is provided with an elastic abutment plate 44. The elastic abutment plate 44 is used for the finger to push the arc plate to move so that the fingerprint panel 2 is exposed and the finger is placed on the fingerprint panel 2. At this time, the spring is in a compressed state; when the finger is disengaged, the spring loses its resistance and generates a restoring force to restore the arc plate. During the restoration process of the arc plate, the cleaning layer 17 wipes the fingerprint panel 2 and blocks the fingerprint panel 2.

[0030] Refer to Figure 5-Figure 9 As shown, the second protective member 5 includes a protective shell 51, the inner wall of the protective shell 51 is connected to the outer end surface of the cylindrical shell 1 by a clip or a thread or a bolt, and the protective shell 51 is provided with a rectangular through groove 53 corresponding to the password input area on the password panel 3, for the user to touch the password input area, while other places are protected by the protective shell 51, and the upper and lower side walls of the rectangular through groove 53 are provided with a slide groove 54, and a moving member 52 is provided at the slide groove 54, and a cleaning layer 17 is provided on the moving member 52. The left and right sides of the rectangular through groove 53 are provided with a placement cavity 55 for placing the moving member 52, and the moving member 52 includes a rectangular bar 6 and a driving part 7. The upper and lower ends of the rectangular bar 6 are provided with sliders that are slidably connected to the slide groove 54, and the slider is connected to the driving part 7. The driving part 7 is provided with two structures, and the corresponding driving part 7 is selected according to actual conditions, such as Figure 8 As shown, the first structure is a rotating rod 8 connected to the slider, and the rotating rod 8 is provided with a driven bevel gear, which is engaged with the main driving rod 10. The main driving rod 10 is provided with an active bevel gear, and the main driving rod 10 is provided with a driven gear, which is engaged with the main gear. The main gear is connected to a motor, and the motor is equipped with a battery power cavity to power the motor. The battery power cavity is set on the protective shell 51. The start of the motor is initiated by the controller. The setting condition is that the door lock is unlocked after the correct password is entered to start the motor, and the fingerprint on the password panel 3 is erased.

[0031] like Figure 9 As shown, another structure comprises a traction rope 14 connected to the slider. The traction rope 14 is connected to a roller 15, which is connected to the motor. A second spring 16 is also provided in the chute 54. One end of the second spring 16 is fixedly connected to one end of the chute 54, and the other end is fixedly connected to one end of the slider. When the correct password is entered and the door lock is unlocked, the motor starts, rotating the roller 15 to retract the traction rope 14. When the traction rope 14 is retracted, the second spring 16 is compressed, and the traction rope 14 moves the rectangular bar 6 laterally with the cleaning layer 17 to achieve cleaning. When the door lock is unlocked after the correct password is entered again, the motor reverses or idles, and the second spring 16 resets to clean the password panel 3. The provision of the second protective member 5 provides protection for the circular smart door lock password panel 3, improving the security of the lock.
