Description

Technical Field

[0001] The present invention relates to the field of locks, and in particular to a lock and a protective mechanism thereof. Background Art

[0002] A lock is a device used for security and access control that can restrict access to an area, item, or building. The basic function of a lock is to ensure that only authorized personnel can open and use a specific door, cabinet, or other storage space. In order to achieve the purpose of not having to carry keys, a touch screen is generally installed on the lock, and the user unlocks the lock by entering a dynamic or static password; the keyless design undoubtedly brings convenience to actual use and avoids the risk of key loss. The dynamic password can be changed after adapting to the mobile terminal through the Bluetooth module, which can avoid the risk of password leakage and improve security to a greater extent.

[0003] However, the existing locks still have the following defects: ① In order to control the touch screen and Bluetooth module, a controller and a power supply for the touch screen, Bluetooth module and controller are set inside the lock body. In order to improve the portability of the lock body, the power supply generally uses a built-in button battery or lithium battery, but the power storage capacity of button batteries and lithium batteries is limited by their size and is generally small. The power supply often needs to be replaced regularly, which is a poor actual experience.

[0004] ② The locking effect of the lock body on the lock head is unreliable; the structure of the existing lock is as shown in the attached Figure 1 As shown, a hollow area 12 is provided inside the lock 11, and a lock execution block 13 and a downward pressure spring 14 are provided inside the lock body. The lock execution block 13 can extend downward into the hollow area 12 to lock the lock 11 under the push of the downward pressure spring 14. Although this method has a simple structure, the locking effect is poor. Under severe shaking, the lock execution block is easy to move up and get unlocked. At the same time, the anti-theft effect is poor. The thief can use a tool to push up the lock execution block so that the lock execution block is separated from the hollow area to unlock the lock and steal. Therefore, it is necessary to optimize the existing structure to improve the stability of the lock execution block after locking the lock. Summary of the invention

[0019] 5. In the present invention, the stabilizing clamping block can pass through the connecting hole. When the short extension section extends downward into the hollow area, the intercepting extension section will touch the boosting auxiliary block to limit the position. At this time, the stabilizing groove will correspond to the position of the connecting hole.

With the continuous introduction of the gaseous medium, the expansion cavity will expand, and the auxiliary block and the lock execution block will be pushed up, and the short extension section will be separated from the hollow area of ​​the lock head, so as to achieve the purpose of unlocking the lock head; the setting of the guide notch can allow the introduction of air medium to push the inner movable block open, so that a gap is generated between the sealing block and the sealing section; the setting of the discharge hole and the micro solenoid valve can automatically discharge the gaseous medium under the control of the controller.

[0022] 8. In the present invention, a micro air pump is used as a driving source. After the micro air pump generates a gaseous medium, it is introduced into the first guide channel through a branch pipe. The present invention takes advantage of the convenient introduction and discharge of the gaseous medium. At the same time, the gaseous medium can be temporarily stored after the micro solenoid valve is closed to allow the lock execution block to maintain an upward state. When the lock head needs to be inserted into the inner locking hole, there is no need to turn on the micro air pump again to control the lock execution block to move upward, thereby simplifying the steps.

The power supply source 24 will supply power to the electrical control component, the touch display screen 233 lights up, the controller 231 and the Bluetooth module 232 work, and when the user needs to change the password, it can be done by interacting with the Bluetooth module 232; when the user enters the correct password on the touch display screen 233, the controller 231 controls the micro air pump to start.

[0040] 3. After the micro air pump is started, it can generate a gaseous medium (air in this embodiment), which is introduced into the guide gap 76 through the branch pipe 221, the first guide channel 71, and the guide cavity 72; as the gaseous medium is continuously introduced, the inner movable block 65 will continuously move to the right, and the firm pressing block 52 will move to the right and hide in the through hole 64, which will not hinder the movement of the boosting main block 43; at the same time, as the inner movable block 54 continues to move to the right, a gap will be generated between the sealing block 752 and the sealing section 74, and the gaseous medium will then be introduced into the expansion cavity 481 through the second guide channel 73, the sealing chamber 63, the second connecting hole 77, the connecting pipe 78 and the first connecting hole 482; as the gaseous medium is continuously introduced, the expansion cavity 481 will expand, so as to push the boosting auxiliary block 45 and the lock execution block 13, and the short extension section 421 will be away from the inner locking hole 211 to avoid hindering the extension of the lock head 11.

[0041] 4. According to the set time, the micro air pump (in this embodiment, the micro air pump has a built-in one-way valve) is automatically closed; at this time, the gaseous medium in the expansion cavity 481 cannot be discharged, and the lock execution block 13 will remain in the upward state. When the lock head 11 needs to be inserted into the inner locking hole 211, there is no need to turn on the micro air pump again to control the lock execution block 13 to move up, which is not only convenient but also can save the power of the power supply 24.

[0042] 5. Insert the lock head 11 into the inner locking hole 211 until the lock head 11 touches the long extension section 422; operate by touching the display screen 233 to open the micro solenoid valve 82, and the gaseous medium in the expanded inner cavity 481 will be continuously discharged from the discharge hole 81; then the lock execution block 13 will continue to move downward under the elastic force of the downward pressure spring 14, and the short extension section 421 in the lock execution block 13 can be guided by the lock execution block 13 to extend downward into the hollow area 12 to lock the lock head 11; at this time, the stabilizing groove 431 will correspond to the position of the connecting hole 411, and the stabilizing pressing block 52 can pass through the connecting hole 411 to the left and press against the stabilizing groove 431, thereby stabilizing the position of the booster main block 43.

[0043] 6. Apply force to rotate the knob 33 in the opposite direction, so that the trigger push block 36 is separated from the trigger switch 37, and the trigger switch 37 is in the cut-off state again.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
