Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, specifically to a password-protected smart lock password leakage prevention device. Background Technology

[0002] A smart lock (also known as an intelligent lock) is a type of lock that differs from traditional mechanical locks in that it is more intelligent in terms of user identification, security, and management. A smart lock is the locking mechanism in an access control system. Electronic locks cannot be called smart locks; the intelligence of a smart lock is demonstrated by its ability to be remotely controlled via smartphone and integrated with smart home systems.

[0003] A known Chinese patent (application number: CN202220239501.5) discloses a password leakage prevention device for a smart lock. The smart lock includes a main body, password input areas on the upper and lower sides of the front of the main body, and a handle. A leakage prevention shell is located on the front of the password input area and above the handle. A guide rail is fixed to the outer left side of the main body and inside the leakage prevention shell. A slider is fixed to the lower inner left side of the leakage prevention shell and slidably mounted on the guide rail. A movable wiping component is fixed to the inner front side of the leakage prevention shell. During the up-and-down movement of the main body, the movable wiping component moves up and down, wiping the password input area and removing residual fingerprints. This maintains cleanliness and prevents thieves from stealing the password based on fingerprints, thus eliminating security risks.

[0004] The above-mentioned technical solution removes fingerprints and prevents password leakage by wiping the pad. However, after long-term use, the surface of the wiping pad is prone to stains. If it continues to be used, not only will the fingerprints not be completely removed, but the stains may even transfer to the password input area, causing the password input area to become dirty. Therefore, a password smart lock password leakage prevention device is proposed. Utility Model Content

[0005] This utility model proposes a password leakage prevention device for a smart lock, which solves the problem in the above-mentioned technical solutions of the related technology that use a wiping pad to remove fingerprints and prevent password leakage. However, after long-term use, the surface of the wiping pad is prone to stains. If continued use is made, not only will fingerprints not be completely removed, but the stains may even transfer to the password input area, causing the password input area to become dirty.

[0006] The technical solution of this utility model is as follows: A password smart lock password leakage prevention device, comprising: a smart password lock and a housing;

[0007] The inner wall of the housing has grooves on both sides, and the inner wall of the grooves has a limiting groove. Multiple first springs are fixedly installed on the inner wall of the housing.

[0012] Preferably, the housing has multiple protrusions on both sides, and the multiple protrusions are arranged sequentially from top to bottom.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] After prolonged use, by tilting the housing to one side, the insert rod rotates inside the groove. Simultaneously, the second spring contracts, disengaging the limiting pin from the mounting slot and tilting the housing. At this point, the soft wiping block can be removed from the rectangular housing for replacement. This effectively prevents dirt from adhering to the surface of the soft wiping block after long-term use, thus avoiding problems with fingerprint removal. After replacing the soft wiping block, by tilting the housing back, the insert rod rotates inside the groove. When the limiting pin aligns with the limiting groove, the second spring drives the limiting pin to reset, inserting it into the limiting groove for fixation. Attached Figure Description

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 5 A password-protected smart lock password leakage prevention device includes: a smart lock 1 and a housing 2;

[0024] Grooves 3 are formed on both sides of the inner wall of the housing 2. Limiting grooves 4 are formed on the inner wall of the grooves 3. Multiple first springs 5 ​​are fixedly installed on the inner wall of the housing 2. One end of the multiple first springs 5 ​​is fixedly connected to a rectangular housing 6. A soft wiping block 7 is provided inside the rectangular housing 6.

[0025] The moving mechanism 12 is set on both sides of the smart combination lock 1. The moving mechanism 12 is provided with a plug rod 8. The plug rod 8 is inserted into the groove 3. The outer wall of the plug rod 8 is provided with an installation groove 9. The inner wall of the installation groove 9 is fixedly installed with a second spring 10. The top of the second spring 10 is fixedly connected to a limit pin 11. The limit pin 11 is inserted into the limit groove 4.

[0026] The technical solution provided by this utility model is as follows: After long-term use, the soft wiping block 7 can be turned to one side by flipping the housing 2, causing the insertion rod 8 to rotate inside the groove 3. At the same time, the second spring 10 retracts, and the limiting pin 11 disengages from the mounting groove 9, causing the housing 2 to tilt. At this time, the soft wiping block 7 can be removed from the rectangular housing 6 and replaced. This effectively prevents the surface of the soft wiping block 7 from accumulating dirt after long-term use, which would affect the removal of fingerprints. After replacing the soft wiping block 7, the housing 2 can be turned back, and the insertion rod 8 can rotate inside the groove 3. When the limiting pin 11 is in the same position as the limiting groove 4, the second spring 10 drives the limiting pin 11 to reset, so that the limiting pin 11 is inserted into the limiting groove 4 for limiting and fixing.

[0027] Furthermore, the moving mechanism 12 includes slide rails 120 disposed on both sides of the smart lock 1, and a slider 121 is slidably connected on the slide rails 120, with one side of the slider 121 connected to the insertion rod 8.

[0028] Specifically, by pulling the housing 2 upward, the slider 121 slides upward on the slide rail 120, thereby exposing the password input area 13 for password input.

[0029] Furthermore, the smart lock 1 has a password input area 13 on the front side and a handle 14 on the front side. The handle 14 is located below the password input area 13. The outer wall of the handle 14 is covered with an anti-slip sleeve 15, which is made of natural rubber.

[0030] Specifically, the password input area 13 is used for users to enter a password. After entering the password, the user holds the handle 14 and turns the handle 14 to open the door. The anti-slip sleeve 15 on the handle 14 is used to prevent the user from slipping when holding the handle 14.

[0031] Furthermore, multiple protrusions 16 are provided on both sides of the housing 2, and the multiple protrusions 16 are arranged sequentially from top to bottom.

[0032] Specifically, multiple protrusions 16 on the housing 2 are used to prevent slippage when the user pulls the housing 2.

[0033] The working principle of this utility model is as follows: By pulling the housing 2 upwards, multiple protrusions 16 on the housing 2 provide anti-slip protection during the pulling process. The slider 121 slides upwards on the slide rail 120, thereby exposing the password input area 13 for password input. After input, the door is opened by the user holding and rotating the handle 14. The anti-slip sleeve 15 on the handle 14 provides anti-slip protection. After long-term use, the soft wiping block 7 can be activated by turning the housing 2 to one side, causing the insertion rod 8 to rotate inside the groove 3. When the second spring 10 retracts, the limiting pin 11 disengages from the mounting groove 9, causing the housing 2 to tilt. At this time, the soft wiping block 7 can be removed from the rectangular housing 6 and replaced. This effectively prevents the surface of the soft wiping block 7 from becoming stained after long-term use, thus preventing the problem of fingerprint removal. After replacing the soft wiping block 7, the housing 2 is flipped back, and the insert rod 8 rotates inside the groove 3. When the limiting pin 11 and the limiting groove 4 are in the same position, the second spring 10 drives the limiting pin 11 to reset, so that the limiting pin 11 is inserted into the limiting groove 4 for limiting and fixing.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
