Description

Technical Field

[0001] This application relates to the field of gas pipelines, and more particularly to a gas pipeline safety locking device. Background Technology

[0002] In gas systems, the safety control of gas pipelines is a crucial aspect of ensuring gas supply safety and preventing gas leaks. Traditional gas pipeline safety locking devices are primarily used to quickly cut off the gas supply in emergencies to prevent fires or explosions caused by gas leaks.

[0003] Currently, some gas pipeline safety interlock devices use a spiral structure for closing or opening. This design involves rotating a handle to move an internal blocking component along a spiral track, thereby sealing or opening the gas pipe. While the spiral design offers relatively good sealing performance and operational stability to some extent, its operation is relatively cumbersome, requiring multiple rotations of the handle to complete the closing or opening action. Especially in emergencies, this can delay the time for rapid gas shut-off, reducing the efficiency of the safety response. Furthermore, the complexity of the spiral structure increases the device's size and occupies a large space, particularly limiting its installation and use in confined environments such as home kitchens or corner areas of industrial plants.

[0004] Therefore, there is a need for a gas pipeline safety latch device that is compact in structure and can be quickly closed or opened. Utility Model Content

[0030] Embodiments of this application provide a gas pipeline safety locking device, comprising:

[0031] A lock cylinder, including an air guide tube extending through the lock cylinder.

[0032] A blocking component is disposed inside the locking cylinder and is perpendicularly disposed on the axis of the air guide tube. The blocking component is used to block or open the air guide tube.

[0033] A handle assembly is disposed adjacent to the air guide tube on one side of the lock cylinder, and the handle assembly is connected to the blocking assembly. The handle assembly controls the movement of the air guide tube along an axis perpendicular to the air guide tube.

[0034] The aforementioned gas pipeline safety locking device, by designing a blocking component within the locking cylinder to be vertically positioned on the gas pipe axis and connected to a handle assembly, achieves a compact and easy-to-operate gas control solution. The handle assembly, located on one side of the locking cylinder, controls the movement of the blocking component in a direction perpendicular to the gas pipe axis, thereby quickly blocking or opening the gas pipe. This design not only simplifies the operation process and improves the efficiency of quickly cutting off gas in emergencies, but also reduces the size of the device, making it easier to use in space-constrained installation environments.

[0035] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] according to Figures 1-4 This application provides a gas pipeline safety locking device 100, including: a locking cylinder 10, a blocking component 30 and a handle component 40.

[0037] The locking cylinder 10 includes an air guide tube 20 passing through the locking cylinder 10, a blocking component 30 disposed inside the locking cylinder 10 and perpendicularly disposed on the axis of the air guide tube 20, the blocking component 30 being used to block or open the air guide tube 20; and a handle assembly 40 disposed adjacent to the air guide tube 20 on one side of the locking cylinder 10, the handle assembly 40 being connected to the blocking component 30, the handle assembly 40 controlling the movement of the air guide tube 20 along an axis perpendicular to the air guide tube 20.

[0038] Specifically, the locking cylinder 10 serves as the main structure, with a gas guide pipe 20 running through it to ensure normal gas flow. The blocking component 30 is vertically positioned on the axis of the gas guide pipe 20, and its up-and-down movement enables precise control of the gas guide pipe 20. This design greatly simplifies the operation process and improves response speed. Placing the handle component 40 adjacent to the gas guide pipe 20 maximizes the use of space on one side of the locking cylinder 10, avoiding unnecessary space waste. This allows operators to more easily access and operate the handle without having to go around or cross other components, improving space utilization and ease of operation. The handle component 40 connects to the blocking component 30; simple manual operation of the handle component 40 drives the blocking component 30 to quickly cut off or restore the gas supply. This design is not only compact and easy to install in corners and other confined spaces, but also simple to operate, making it particularly suitable for emergency gas shut-off applications such as home kitchens and industrial plants, effectively improving the safety and reliability of the gas system.

[0039] Furthermore, when a gas leak or other emergency is detected, the operator can quickly pull or push the handle assembly 40 to move the blocking assembly 30 along the axis of the vertical gas pipe 20, thereby quickly cutting off the gas supply.

[0040] In one specific embodiment, the lock cylinder 10 further includes a placement hole 11. When viewed along the axial direction of the air guide tube 20, the extension direction of the placement hole 11 is perpendicular to the axial direction of the air guide tube 20, and the placement hole 11 is connected to the air guide tube 20.

[0041] Specifically, the placement hole 11 extends perpendicularly to and communicates with the axis of the air duct 20, and is used to place the blocking component 30. When the blocking component 30 is in use, it moves along the extension direction of the placement hole 11 to form a cavity, allowing the blocking component 30 to close or open the air duct 20 in the extension direction of the placement hole 11. The placement hole 11 also greatly facilitates the maintenance and internal inspection of the blocking component 30.

[0042] In one specific embodiment, the lock cylinder 10 further includes a first side 12 and a second side 13 disposed opposite to the first side 12, and the air guide pipe 20 includes a first port 21 and a second port 22 disposed opposite to the first port 21. The first port 21 is disposed on the first side 12, and the second port 22 is disposed on the second side 13.

[0043] Specifically, the lock cylinder 10 is divided into a first side 12 and a second side 13. The two ends of the gas guide pipe 20 are respectively located on these two sides, forming the inlet and outlet of the gas pipeline. This creates a complete channel inside the lock cylinder 10 for transmitting gas. This design not only facilitates the connection and installation of the gas pipeline, but also ensures that the position of the gas guide pipe 20 inside the lock cylinder 10 is fixed and unique, and it cooperates well with other components inside the lock cylinder 10, thus effectively avoiding the risk of gas leakage.

[0044] In one specific embodiment, the lock cylinder 10 further includes a fixing hole 14, which is disposed on the first side 12 and communicates with the air guide tube 20. The handle assembly 40 is disposed on the fixing hole 14.

[0045] Specifically, the fixing hole 14 provides a stable mounting point for the handle assembly 40, ensuring that the handle assembly 40 can be firmly fixed to the lock cylinder 10 via a threaded connection, and is not easy to fall off or loosen. The fixing hole 14 is located on the first side 12 of the lock cylinder 10 and is connected to the air guide tube 20.

[0046] The handle assembly 40 extends axially into the fixing hole 14 along the air guide tube 20 and is connected to the fixing hole 14 via a threaded connection. The connection between the fixing hole 14 and the handle assembly 40 makes the lock structure more compact and reduces unnecessary space occupation.

[0047] In one specific embodiment, the blocking assembly 30 includes a first connecting shaft 31 and a blocking plate assembly 32. One end of the first connecting shaft 31 is disposed on the fixing hole 14, and the other end is connected to the blocking plate assembly 32. The blocking plate assembly 32 is perpendicularly disposed on the axis of the air guide tube 20.

[0048] Specifically, one end of the first connecting shaft 31 is fixed to the fixing hole 14, and the other end is connected to the blocking plate assembly 32, so that the blocking plate assembly 32 can rotate around the fixing hole 14 connected to the first connecting shaft 31. The blocking plate assembly 32 moves along the axis of the air guide tube 20 toward the placement hole 11, and the blocking plate assembly 32 connects the air guide tube 20.

[0049] Furthermore, when the device is in the off state, the blocking plate assembly 32 can completely block the flow of gas to prevent any leakage; and when the gas needs to be turned on, the blocking plate assembly 32 will quickly move away to ensure that the gas can flow smoothly.

[0050] In one specific embodiment, the handle assembly 40 includes a second connecting shaft 41 and a control handle 42. The second connecting shaft 41 is embedded in the fixing hole 14, and one end of the second connecting shaft 41 is connected to the first connecting shaft 31, while the other end extends out of the fixing hole 14 and is connected to the control handle 42.

[0051] Specifically, the second connecting shaft 41 is embedded in the fixing hole 14, and a threaded screw is fitted around the outer ring of the second connecting shaft 41. The screw engages with the thread on the fixing hole 14, fixing the second connecting shaft 41 within the fixing hole 14 and restricting its position. One end is tightly connected to the first connecting shaft 31 in the blocking assembly 30, while the other end extends out of the fixing hole 14, seamlessly connecting with the control handle 42. This design not only ensures the accuracy and stability of the transmission but also, through its reasonable layout, makes the entire operation process smoother and more natural, reducing unnecessary friction and wear. During operation, the user only needs to push or pull the control handle 42, causing the second connecting shaft 41 to rotate, thereby driving the first connecting shaft 31 and the blocking plate assembly 32 to move along the direction of the placement hole 11, achieving rapid blocking or opening of the air duct 20.

[0052] In one specific embodiment, the first connecting shaft 31 includes a first limiting hole 311, which is located at one end away from the blocking plate assembly 32, and is disposed opposite to the fixing hole 14; the second connecting shaft 41 includes a first limiting block 411, which is disposed in the first limiting hole 311, and the shape of the first limiting block matches that of the first limiting hole 311.

[0053] Specifically, the first limiting hole 311 is used to cooperate with the first limiting block 411 on the second connecting shaft 41 to realize the limiting function of the connecting shaft. The limiting hole usually has a specific shape and size to ensure that only the matching part can be inserted and fixed. The first limiting block 411 can ensure the stability of the first connecting shaft 31 in a specific position and prevent unnecessary movement or misalignment during use.

[0054] In one specific embodiment, the second connecting shaft 41 includes a second limiting block 412, which is disposed at one end away from the first limiting block 411; the control handle 42 includes a second limiting hole 421, which is disposed opposite to the fixing hole 14, and the second limiting block 412 is disposed within the second limiting hole 421, and the shape of the second limiting block 412 matches that of the second limiting hole 421.

[0055] Specifically, the second limiting block 412 is located at the end away from the first limiting block 411, and is used to cooperate with the control handle 42 to realize the control connection between the control handle 42 and the second connecting shaft 41, so that the control handle 42 controls the rotation direction of the second connecting shaft 41. A second limiting hole 421 is designed on the control handle 42, which is opposite to the fixing hole 14, and is used to cooperate with the second limiting block 412 on the second connecting shaft 41.

[0056] In one specific embodiment, the diameter of the blocking plate assembly 32 is larger than the diameter of the air duct 20.

[0057] Specifically, the diameter of the blocking plate assembly 32 is larger than the diameter of the gas guide pipe 20, ensuring that the blocking plate assembly 32 can form an effective seal when blocking the gas guide pipe 20, preventing gas leakage and improving the safety performance of the device.

[0058] In one specific embodiment, the lock cylinder 10 further includes a sealing cover 50, which is disposed on the placement hole 11.

[0059] Specifically, the lock cylinder 10 also includes a sealing cover 50, which is located on the placement hole 11. This not only prevents external impurities from entering the interior of the lock cylinder 10 and affecting the normal operation of the blocking component 30, but also maintains the overall aesthetics and cleanliness of the device, thus enhancing the user experience.

[0060] Therefore, the gas pipeline safety locking device 100 provided above achieves a compact and easy-to-operate gas control solution by designing the blocking component 30 inside the locking cylinder 10 to be vertically mounted on the axis of the gas pipe 20 and connected to the handle assembly 40. The handle assembly 40 is located on one side of the locking cylinder 10 and controls the movement of the blocking component 30 in a direction perpendicular to the axis of the gas pipe 20, thereby quickly blocking or opening the gas pipe 20. This design not only simplifies the operation process and improves the efficiency of quickly cutting off gas in emergencies, but also reduces the size of the device, making it easier to use in space-constrained installation environments.

[0061] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
