Description

Technical Field

[0001] The utility model relates to the technical field of password locks, in particular to an improved intelligent password lock emergency unlocking mechanism. Background Art

[0002] At present, the smart password locks on the market are deeply loved by consumers because of their convenience. Smart password locks usually control the motor to start unlocking through password buttons or fingerprint recognition devices. When the battery of the smart password lock is out of power, or the electric unlocking fails, an emergency unlocking device is required to unlock the door. At present, the emergency unlocking devices of smart password locks are all implemented with keys. This emergency unlocking method requires relying on keys. Once the door lock battery is out of power due to a long time away, and the emergency unlocking key is forgotten, the door lock cannot be opened and the lock needs to be removed to enter the door. Therefore, a password lock emergency unlocking mechanism is set, and a roller lock is used instead of a key. The lock can be unlocked by turning the roller and entering the password.

[0003] However, the existing processing equipment has the following shortcomings:

[0004] In the existing equipment, the roller lock is directly exposed on the surface of the equipment. The exposed roller lock is easily affected by external factors, causing certain damage to the body of the roller lock, making it difficult for the wheel lock to operate normally and causing the situation of unlocking.

[0005] Therefore, we have proposed an improved intelligent password lock emergency unlocking mechanism to solve the above-mentioned problems. Utility Model Content

[0008] Furthermore, a pressing groove is provided on the side of the protective cover, and a limiting hole is provided inside the first connecting plate. By arranging a protective cover on the surface of the first connecting plate, the roller lock can be protected, thereby reducing the risk of the roller lock being easily damaged when the device is in use.

[0009] Furthermore, a stop block is slidably connected to the inner wall of the pressing groove, one end of the stop block is fixedly connected to a stop rod, and the stop rod is clamped with the inside of the limiting hole. The stop rod is provided to facilitate limiting the protective cover.

[0010] Furthermore, one end of the stop block away from the stop rod is fixedly connected to a second spring, and one end of the second spring away from the stop block is fixedly connected to the inner wall of the pressure groove. The second spring is provided to facilitate applying a restoring elastic force to the stop block.

[0011] Furthermore, a pressing device is provided inside the first connecting plate, and the pressing device includes a pressing hole and a pressing block. The pressing hole is opened on the side of the first connecting plate, and the pressing block is slidably connected to the inner wall of the pressing hole. One end of the pressing block is fixedly connected to a pressing rod. By providing the pressing device, the push rod is effectively moved, which plays a role in moving the push rod. When the equipment is used, the push rod is combined with the inside of the first connecting plate. When the protective cover needs to be opened, the user needs to use a special tool to operate to open the protective cover. The use of special tools is not only too cumbersome, but also easy to lose, making it difficult for the user to open the protective cover, thereby improving the practicability of the equipment.

[0012] Furthermore, one end of the pressure rod is in contact with one end of the support rod, and the pressure rod is provided to facilitate the movement of the support rod.

[0013] Furthermore, a third spring is fixedly connected to the surface of the pressing block, and one end of the third spring away from the pressing block is fixedly connected to the inner wall of the pressing hole.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, when using the device, the user installs the device on the door. When the device has no electricity, the user rotates the roller lock, aligns the password, and locks the device. When using the device, the user rotates the protective cover to move, and then the first spring generates elastic force, and then the push rod is moved. The movement of the push rod drives the second spring to displace and deform to generate elastic force, and then the push rod is engaged with the inside of the limiting hole to limit the protective cover. By setting the protective device, the roller lock is effectively protected, and the roller lock is protected. When the device is in use, since the roller lock is set on the surface of the first connecting plate, when not in use, the roller lock is exposed to the surface of the device, which is easy to be played by children or bumped by foreign objects, causing certain wear and damage to the roller lock, resulting in the roller lock being unable to roll and use normally. The protective cover can protect the surface of the roller lock, thereby improving the protection of the roller lock itself.

[0016] 2. In the utility model, by setting a pressing device, when using the equipment, the user presses the pressing block, and then the pressing block moves to drive the pressure rod to move, and the pressure rod moves to drive the push rod to move. When the pressing block moves, it drives the third spring to displace and deform to generate elastic force. By setting a pressing device, the push rod is effectively moved, which plays a role in moving the push rod. When using the equipment, the push rod is combined with the inside of the first connecting plate. When the protective cover needs to be opened, the user needs to use special tools to operate to open the protective cover. The use of special tools is not only too cumbersome, but also easy to lose, which makes it difficult for the user to open the protective cover, thereby improving the practicality of the equipment.

[0023] See also Figure 1-5 The utility model provides a technical solution: an improved intelligent password lock emergency unlocking mechanism, including a first connecting plate 1 and a protective device 6, one end of the first connecting plate 1 is fixedly connected to the second connecting plate 2, the surface of the first connecting plate 1 is provided with a display screen 4, the surface of the first connecting plate 1 is provided with a handle 3, and the surface of the first connecting plate 1 is provided with a roller lock 5.

[0024] The specific arrangement and function of the protection device 6 and the pressing device 7 will be described in detail below.

[0025] In this embodiment: the protection device 6 is arranged on the surface of the first connecting plate 1, the protection device 6 includes a protection cover 61 and a rotation groove 62, the rotation groove 62 is opened inside the first connecting plate 1, the protection cover 61 is arranged on the surface of the roller lock 5, the side of the protection cover 61 is fixedly connected with a rotating column 64, the interior of the rotating column 64 is provided with a groove 65, the inner wall of the rotation groove 62 is provided with a limiting groove 63, the inner wall of the groove 65 is fixedly connected with a rotating rod 66, the rotating rod 66 is rotatably connected to the inside of the limiting groove 63, the inner wall of the groove 65 is fixedly connected with a first spring 67, and the end of the first spring 67 away from the groove 65 is fixedly connected to the inside of the rotation groove 62.

[0026] Specifically, a pressing groove 68 is provided on the side of the protection cover 61 , and a limiting hole 69 is provided inside the first connecting plate 1 .

[0027] In the present embodiment: the protective cover 61 is rotatably connected to the surface of the first connecting plate 1, and can completely cover and protect the surface of the roller lock 5. The function of the protective cover 61 is to cover and hide the roller lock 5, and at the same time to protect the surface of the roller lock 5 from dust, thereby reducing the risk of dust in the air easily accumulating on the surface of the roller lock 5 when the device is used. When the device is installed on the door lock, the dust in the air is easily accumulated on the surface of the roller lock 5. When the user rolls the roller lock 5 to unlock it, the dust is easily brought into the roller lock 5, causing the inside of the roller lock 5 to be stuck and blocked, making it difficult to rotate the roller lock 5 to unlock it.

[0028] Specifically, the inner wall of the pressing groove 68 is slidably connected with a stop block 611, one end of the stop block 611 is fixedly connected with a stop rod 610, and the stop rod 610 is clamped with the inside of the limiting hole 69. The stop block 611 arranged inside the pressing groove 68 can effectively limit the stop rod 610. Without the stop block 611, it is easy for the stop rod 610 to completely detach from the inside of the pressing groove 68, making it difficult for the stop rod 610 to limit the protective cover 61.

[0029] Specifically, one end of the stop block 611 away from the stop rod 610 is fixedly connected to the second spring 612, and one end of the second spring 612 away from the stop block 611 is fixedly connected to the inner wall of the pressure groove 68. The second spring 612 arranged on the side of the stop block 611 can apply a reset elastic force to the stop block 611. When the stop block 611 applies pressure, the shape of the second spring 612 is changed, and the elastic force of the second spring 612 is increased, so that when the stop block 611 loses pressure, the second spring 612 releases the elastic force and pushes the stop block 611 out to fit tightly with the inside of the pressure groove 68 to limit the position.

[0030] In this embodiment: a pressing device 7 is arranged inside the first connecting plate 1, and the pressing device 7 includes a pressing hole 71 and a pressing block 72. The pressing hole 71 is opened on the side of the first connecting plate 1, and the pressing block 72 is slidably connected to the inner wall of the pressing hole 71. One end of the pressing block 72 is fixedly connected to a pressing rod 73.

[0031] In this embodiment: the pressing device 7 arranged inside the first connecting plate 1 can effectively push the push rod 610 on the side of the protective cover 61. The process of pushing the push rod 610 out of the limiting hole 69 is the pressing device 7. Generally, the push rod 610 is moved out of the limiting hole 69. The user needs to use a special tool to insert the tool into the first connecting plate 1, push the push rod 610, and then the protective cover 61 opens. The use of special tools is not only too cumbersome, but also easy to lose the tool. In the case where it is difficult to quickly open the protective cover 61, the pressing device 7 can quickly open the protective cover 61, thereby improving the convenience of use for users.

[0032] Specifically, one end of the pressure rod 73 abuts against one end of the push rod 610. The pressure rod 73 is arranged inside the pressure hole 71, and the push rod 610 can be mechanically moved, so that the push rod 610 can be moved out of the limiting hole 69 quickly and conveniently to open the protective cover 61.

[0033] Specifically, a third spring 74 is fixedly connected to the surface of the pressing block 72, and one end of the third spring 74 away from the pressing block 72 is fixedly connected to the inner wall of the pressing hole 71. The pressing block 72 is arranged at the end of the pressing rod 73 close to the outside, which is convenient for the user to effectively apply pressure.

[0034] Working principle: when using the device, the user installs the device on the door. When the device has no power, the user rotates the roller lock 5, aligns the password, and installs the device. When using the device, the user rotates the protective cover 61 to move, and then the first spring 67 generates elastic force, and then the push rod 610 is moved. The movement of the push rod 610 drives the second spring 612 to displace and deform to generate elastic force, and then the push rod 610 is engaged with the inside of the limiting hole 69 to limit the protective cover 61. By setting the protection device 6, the roller lock 5 is effectively protected, and the role of protecting the roller lock 5 is played. When using the device, since the roller lock 5 is set on the surface of the first connecting plate 1, when not in use, the roller lock 5 is exposed on the surface of the device, it is easy to be played by children or knocked by foreign objects, causing certain wear and damage to the roller lock 5, resulting in the situation that the roller lock 5 cannot be rolled and used normally. The protective cover 61 can protect the surface of the roller lock 5, thereby improving the protection of the roller lock 5 itself.

[0035] When using the device, the user presses the pressure block 72, and then the pressure block 72 moves to drive the pressure rod 73 to move, and the pressure rod 73 moves to push the push rod 610 to move. When the pressure block 72 moves, it drives the third spring 74 to displace and deform to generate elastic force. By setting the pressing device 7, the push rod 610 is effectively moved, which plays a role in moving the push rod 610. When using the device, the push rod 610 is combined with the inside of the first connecting plate 1. When the protective cover 61 needs to be opened, the user needs to use a special tool to operate to open the protective cover 61. The use of special tools is not only too cumbersome, but also easy to lose, resulting in difficulty in using and opening the protective cover 61, thereby improving the practicability of the device.
