Description

Technical Field

[0001] This utility model relates to the field of valve locks, and in particular to an intelligent valve lock. Background Technology

[0002] With the rapid pace of urbanization in China, the design of public area pipeline valves by early developers, due to cost and space constraints, is often simplistic and susceptible to vandalism. Furthermore, the arbitrary opening or closing of these valves can cause unnecessary losses for users, increase management burdens, and easily lead to group lawsuits. To protect the interests of users and related personnel, valve lock boxes are installed on the pipeline valves to lock them, thus preventing unauthorized opening or closing.

[0003] In traditional technology, the valve lock box is directly fitted onto the valve, and the opening and closing of the valve lock box allows for the exposure or closure of the valve joint. However, the existing valve lock box has a simple locking structure design, making it easy for people to damage it. This allows the valve lock box to be opened at will, posing a problem of theft. At the same time, the valve lock box generally uses a key to open or lock, which has poor security performance and is susceptible to malicious unlocking. Therefore, it is not very practical and has a limited range of applications.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an intelligent valve lock. It utilizes the rotation of the rotating shaft to make the protrusion contact or separate from the movable pin, thereby achieving locking or unlocking between the upper and lower boxes. With the addition of a sensing and remote communication control module, it eliminates the use of traditional key unlocking, reduces the possibility of malicious unlocking, has excellent security performance, and a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] As a preferred embodiment, the device also includes a vandal-proof alarm, which is mounted on the first PCB board. The vandal-proof alarm has an upward-resetting elastic boss that protrudes from the upper end of the lower housing. When the lower and upper housings are locked, the upper housing acts downward on the elastic boss to press it down. When the lower and upper housings are maliciously unlocked, the elastic boss pops up and resets. The vandal-proof alarm then sends information back to the first PCB board and notifies the user via a remote communication control module.

[0015] As a preferred embodiment, a fastener is provided on the other end of the lower box body.

[0020] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves a movable snap-lock between the movable pin and the latch under the action of the elastic reset component through the design of each component. The rotation of the rotating shaft causes its protrusion to contact the movable pin, preventing the movable pin from retracting and locking it with the latch. Alternatively, when the rotating shaft rotates to its concave position and is opposite to the movable pin, the movable pin has room to retract and can be unlocked with the latch. This achieves locking or unlocking between the upper and lower boxes.

At the same time, the limiting part and the limiting step are designed to limit the movement of the movable pin on the movable slot, which improves the stability of the movable pin. Furthermore, the anti-vandalism alarm uses the movement of the elastic boss to detect whether the product has been unlocked without an unlocking command. When the product has been unlocked without an unlocking command, the anti-vandalism alarm sends the information to the first PCB board. The first PCB board then notifies the user through the remote communication control module, thereby improving the anti-theft performance of the product and ensuring its usability.

[0022] Furthermore, the design of the snap fasteners and slots enhances the locking stability between the upper and lower boxes. Combined with the waterproof rubber ring, the snap fasteners' snap-fit ​​against the slots in the upper box compresses and deforms the waterproof rubber ring, sealing the interior of the lock box for waterproofing. Simultaneously, the second positioning part and second positioning hole facilitate the connection and positioning between the first and second locking parts, improving their ability to lock the valve connector. Moreover, the connection part and connection groove facilitate the assembly and positioning of the locking parts on the corresponding boxes, allowing for the assembly of appropriate locking parts according to different valve connectors, thus meeting the usage requirements of various valve connectors and ensuring excellent usability.

In this way, through the design of each component, the rotation of the rotating shaft 24 causes the protrusion 241 to contact the movable pin 22, so that the movable pin 22 cannot retract and is locked with the latch 21. Alternatively, the rotation of the rotating shaft 24 causes the recess 242 to correspond to the movable pin 22, so that the movable pin 22 can be moved back to the recess 242. Thus, the locking or unlocking between the upper box 11 and the lower box 12 is realized. With the setting of the sensing module and the remote communication control module, the use of traditional key unlocking is eliminated, the possibility of malicious unlocking is reduced, the security performance is good, the practicality is strong, the user needs are met, and the application range is wide.

[0055] In this embodiment, the latch 21 has a mounting plate 211, which has an extension 212 extending downward toward the locking groove 121.

Two extensions 212 and two latching parts 213 are arranged at left-right intervals at the lower end of the mounting plate 211. Correspondingly, two movable pins 22 and two elastic reset members 23 are arranged at left-right intervals on the lower housing 12. The rotation... The shaft 24 is disposed between two movable pins 22. The rotating shaft 24 has two protrusions 241 and two recesses 242. Specifically, the lower end of the upper box 11 is provided with a first positioning part 112, and the latch 21 is provided with a first positioning hole 214. The first positioning part 112 is adapted to the first positioning hole 214 to realize the assembly and positioning of the latch 21 on the upper box 11. Thus, the first positioning part 112 and the first positioning hole 214 are provided to facilitate the assembly and positioning of the latch 21 on the upper box 11.

[0056] The lower housing 12 is internally provided with a mounting bracket 14. A movable groove 122 and a mounting groove 123 are formed between the mounting bracket 14 and the lower housing 12.

The movable pin 22 is disposed on the movable groove 122, and the rotating shaft 24 is disposed on the mounting groove 123. A limiting part 221 is provided on the outer side of the movable pin 22, and a limiting step 124 is provided on the movable groove 122. The two ends of the elastic reset member 23 act on the limiting part 221 and the movable groove 122 respectively. Preferably, the elastic reset member 23 is a spring. In this way, the setting of the limiting part 221 and the limiting step 124 realizes the movement limitation of the movable pin 22 on the movable groove 122, thereby improving the stability of the movable pin 22 in use.

[0057] The device also includes an anti-vandalism alarm 15, which is mounted on the first PCB board 13. The anti-vandalism alarm 15 has an upwardly repositionable elastic boss 151 that protrudes from the upper end of the lower housing 12. When the lower housing 12 and the upper housing 11 are locked, the upper housing 11 acts downward on the elastic boss 151 to keep it in a depressed state. When the lower housing 12 and the upper housing 11 are maliciously unlocked, the elastic boss 151 pops up and resets. The anti-vandalism alarm 15 feeds back the information to the first PCB board 13 and notifies the user through the communication module. Thus, the anti-vandalism alarm 15 uses the action of the elastic boss 151 to detect whether the product has been unlocked without an unlocking command. When the product has been unlocked without an unlocking command, the anti-vandalism alarm 15 feeds back the information to the first PCB board 13, and the first PCB board 13 notifies the user through the communication module, thereby improving the anti-theft performance of the product and enhancing its usability.

[0058] Furthermore, a buckle 16 is provided on the other end of the lower box 12.

The second positioning hole 103 and the second positioning part 102 are matched and connected to each other.

[0061] Specifically, the first locking member 18 is detachably mounted on the upper box 11, and the second locking member 19 is detachably mounted on the lower box 12. Both the first locking member 18 and the second locking member 19 are provided with connecting parts 104. The upper box 11 and the lower box 12 are provided with connecting grooves 105 corresponding to the connecting parts 104. The connecting parts 104 are adapted to be positioned on the connecting grooves 105 of the corresponding boxes, and are sequentially connected to the connecting parts 104 and the connecting grooves 105 by locking fasteners 106, so as to realize the assembly connection of the corresponding locking members on the boxes. In this way, the setting of the second positioning part 102 and the second positioning hole 103 is conducive to the connection and positioning between the first locking member 18 and the second locking member 19, improving the locking use of the first locking member 18 and the second locking member 19 for valve joints. Moreover, the setting of the connecting part 104 and the connecting groove 105 is conducive to the assembly and positioning connection of the locking members on the corresponding boxes, and the corresponding locking members are assembled according to different valve joints, thereby meeting the usage requirements of different valve joints and having good usability.

[0062] The key design feature of this utility model lies in the fact that, through the design of each component, the movable pin can be movably locked with the latch under the action of the elastic reset component. The rotation of the rotating shaft causes its protrusion to contact the movable pin, preventing the movable pin from retracting and locking it with the latch. Alternatively, when the rotating shaft rotates to its concave position and aligns with the movable pin, the movable pin has room to retract and can be unlocked with the latch. This achieves locking or unlocking between the upper and lower boxes. Combined with the setting of the sensing module, the use of traditional key unlocking is eliminated, reducing the possibility of malicious unlocking. It has excellent security performance, strong practicality, meets user needs, and has a wide range of applications.

[0063] Secondly, the first positioning part and the first positioning hole are designed to facilitate the assembly and positioning of the latch on the upper box. At the same time, the limiting part and the limiting step are designed to limit the movement of the movable pin on the movable slot, which improves the stability of the movable pin. Furthermore, the anti-vandalism alarm uses the movement of the elastic boss to detect whether the product has been unlocked without an unlocking command. When the product has been unlocked without an unlocking command, the anti-vandalism alarm sends the information to the first PCB board. The first PCB board then notifies the user through the communication module, thereby improving the anti-theft performance of the product and ensuring its usability.

[0064] Furthermore, the design of the snap fasteners and slots enhances the locking stability between the upper and lower boxes. Combined with the waterproof rubber ring, the snap fasteners' snap-fit ​​against the slots in the upper box compresses and deforms the waterproof rubber ring, sealing the interior of the lock box for waterproofing. Simultaneously, the second positioning part and second positioning hole facilitate the connection and positioning between the first and second locking parts, improving their ability to lock the valve connector. Moreover, the connection part and connection groove facilitate the assembly and positioning of the locking parts on the corresponding boxes, allowing for the assembly of appropriate locking parts according to different valve connectors, thus meeting the usage requirements of various valve connectors and ensuring excellent usability.
