Description

Technical Field

[0001] This utility model relates to the field of controller support technology, specifically a quick-assembly and disassembly support structure for a gas valve controller. Background Technology

[0002] Natural gas is typically transported via pipelines to urban gas distribution centers and industrial enterprises for use. Because these pipelines are buried underground for extended periods, and some sections involve outdoor environments, they are susceptible to soil corrosion and aging, increasing the risk of leaks. Since most existing gas pipelines are already in place, in the event of a leak, personnel must manually reach the gas valve well to shut off the valve. Since the valves are often located inside the well, requiring personnel to enter and operate them, this process is not only time-consuming and labor-intensive but may also exacerbate the accident due to delayed response.

[0003] To reduce the hazards of leak accidents, remote control of gas valve opening and closing has become a key solution. Chinese patent CN202222669854.1 discloses an easy-to-install automatic gas valve opening and closing device. While it achieves remote valve closing, the structural design of its core component, the electric actuator, has significant flaws. This structure consists of three independently adjustable support rods and threaded extension rods. Installation requires calibrating the length of each support rod and adjusting the thread tightness, making the process cumbersome and time-consuming. Similarly, disassembly and maintenance require loosening each component step by step, greatly impacting emergency response efficiency.

[0004] Another type of mainstream support structure uses a double telescopic rod load-bearing controller, such as... Figure 5 As shown, its adjustment method still relies on the traditional nut thread locking mechanism, requiring the nuts of the two rods to be turned separately to control the extension length. This not only makes it difficult to unify the adjustment accuracy, but also requires repeated turning operations during disassembly and assembly, resulting in a long installation or disassembly time for a single set of structures. This inefficient disassembly and assembly method cannot meet the needs of emergency repair of gas pipelines and rapid deployment of controllers, and also increases the cost of manual operation and maintenance.

[0005] Addressing the core pain points of existing support structures, such as numerous disassembly and assembly steps and low adjustment efficiency, there is an urgent need to develop a simple, easy-to-operate, and quick-disassembly support structure to adapt to the rapid installation, maintenance, and replacement requirements of gas valve controllers in different scenarios. Therefore, a quick-disassembly gas valve controller support structure is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a quick-assembly and disassembly support structure for a gas valve controller, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly and disassembly gas valve controller support structure, comprising two main rods, each of the two main rods having a telescopic rod slidably connected to the inner side of one end, a first snap-fit ​​plate snapping onto the outer side of the two main rods, and a second snap-fit ​​plate snapping onto the outer side of the two telescopic rods;

[0008] A housing is installed in the middle of the first snap-fit ​​plate, a pull rod is installed through one side of the housing, a second toothed plate is installed at one end of the pull rod, and a spring is installed on the outside of the pull rod;

[0009] A first toothed plate is slidably connected to the other side of the interior of the housing. The first toothed plate is adapted to a second toothed plate. A connecting rod is hinged to the top of the first toothed plate, and the other end of the connecting rod is hinged to the middle of the upper surface of the second snap-fit ​​plate.

[0010] Preferably, a first hinge seat is installed in the middle of the second snap-fit ​​plate, a second hinge seat is installed on the top of the first toothed plate, and the two ends of the connecting rod are respectively hinged to the first hinge seat and the second hinge seat.

[0011] Preferably, a first limiting ring is installed on the outer side of both the main rod and the telescopic rod to limit the first and second locking plates.

[0012] Preferably, both ends of the first and second snap-fit ​​plates are integrally formed with an arc-shaped snap ring located between the two first limiting rings.

[0013] Preferably, the pull rod is mounted on the outer side wall outside the housing with a second limiting ring for limiting the position of the second toothed plate.

[0014] Compared with existing technologies, the advantages of this utility model are: pressing the first toothed plate drives the telescopic rod to extend and fix itself, eliminating the need for step-by-step calibration or repeated tightening, greatly simplifying the operation process. Disassembly and assembly are extremely convenient; pulling the lever releases the toothed plate engagement lock, significantly improving efficiency and overcoming the limitations of traditional threaded locking mechanisms. This allows for rapid installation and disassembly, meeting the needs of emergency repairs of gas pipelines and rapid deployment of controllers, while reducing manual maintenance costs.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a quick-assembly and disassembly gas valve controller support structure, including two main rods 1, which serve as basic support components. Each main rod 1 has a telescopic rod 2 slidably connected to its inner side at one end. The telescopic rod 2 can slide along the inner axial direction of the main rod 1 to achieve overall length adjustment. A first snap-fit ​​plate 3 is snapped onto the outer side of each main rod 1, serving to fix and support subsequent components. A second snap-fit ​​plate 4 is snapped onto the outer side of each telescopic rod 2, and the second snap-fit ​​plate 4 moves synchronously with the telescopic rod 2. A housing 6 is fixedly installed in the middle of the first snap-fit ​​plate 3, providing installation space for internal components. A pull rod 12 is installed through one side of the housing 6, allowing it to move laterally along the housing 6. A second toothed plate 10 is fixedly installed at one end of the pull rod 12, and a spring 11 is fitted onto the outer side of the pull rod 12, generating an elastic restoring force when the pull rod 12 moves. A first toothed plate 7 is slidably connected to the other side of the interior of the housing 6. The first toothed plate 7 and the second toothed plate 10 mesh with each other to achieve locking or unlocking functions. The teeth on the first toothed plate 7 and the second toothed plate 10 are similar to the structure of a cable tie. When the first toothed plate 7 is pressed down, it can move smoothly downward. However, when the first toothed plate 7 is pulled upward, the second toothed plate 10 will restrict the position of the first toothed plate 7. The first toothed plate 7 can only be pulled upward when the second toothed plate 10 is separated from the first toothed plate 7. A connecting rod 5 is hinged to the top of the first toothed plate 7. The other end of the connecting rod 5 is hinged to the middle of the upper surface of the second locking plate 4. This can convert the sliding of the first toothed plate 7 into the displacement of the second locking plate 4, thereby driving the telescopic rod 2 to complete the telescopic adjustment.

[0023] like Figure 3 and Figure 4As shown: A first hinge seat 8 is fixedly installed in the middle of the second snap plate 4, and a second hinge seat 9 is fixedly installed on the top of the first toothed plate 7. The two ends of the connecting rod 5 are respectively hinged to the first hinge seat 8 and the second hinge seat 9. This structure can ensure that the connecting rod 5 rotates smoothly during the transmission process, avoid jamming, and at the same time realize the stable transmission of force, ensuring the smoothness of the adjustment process of the telescopic rod 2.

[0024] like Figure 4 As shown: A first limiting ring 13 is fixedly installed on the outer side of both the main rod 1 and the telescopic rod 2. The first limiting ring 13 is used to limit the axial displacement of the first locking plate 3 and the second locking plate 4, to prevent the first locking plate 3 from moving arbitrarily on the main rod 1 and the second locking plate 4 from moving arbitrarily on the telescopic rod 2, and to ensure the connection stability of the overall structure.

[0025] like Figure 1 and Figure 2 As shown: Both ends of the first snap-fit ​​plate 3 and the second snap-fit ​​plate 4 are integrally formed with arc-shaped snap rings. The arc-shaped snap rings are located between the two first limiting rings 13. Their curvature matches the curvature of the outer wall of the main rod 1 and the telescopic rod 2, which can enhance the fit between the snap-fit ​​plate and the rod body and improve the snap-fit ​​firmness.

[0026] like Figure 3 As shown: A second limiting ring 14 is fixedly installed on the outer side wall of the outer side of the housing 6. The second limiting ring 14 is used to limit the extreme position of the second toothed plate 10 to prevent the second toothed plate 10 from extending too far into the housing 6 and causing it to be unable to be effectively inserted with the first toothed plate 7.

[0027] Working Principle: First, place the device at a preset height inside the valve well, aligning the pointed ends of the two main rods 1 with the pre-drilled holes or brick seams on the inner wall of the valve well to complete the initial positioning. Hold the first locking plate 3 with both hands to keep the device stable, then press down on the first toothed plate 7. Because the first toothed plate 7 and the second toothed plate 10 adopt a one-way meshing structure similar to a cable tie, the second toothed plate 10 will not hinder the downward movement of the first toothed plate 7 when pressed, and the spring 11 is in a naturally extended state at this time, providing continuous meshing pressure for the second toothed plate 10. When the first toothed plate 7 slides downward, it drives one end of the connecting rod 5 to move downward synchronously through the second hinge seat 9 at the top. The other end of the connecting rod 5 transmits force through the first hinge seat 8 in the middle of the second locking plate 4, causing the second locking plate 4 to move outward along the axial direction of the telescopic rod 2. Because the arc-shaped retaining rings at both ends of the second retaining plate 4 are restricted by the two first limiting rings 13 on the outside of the telescopic rod 2, they will not deviate during the movement, thus stably driving the two telescopic rods 2 to extend axially along the inner side of the main rod 1 until the end of the telescopic rod 2 is inserted into the corresponding hole or brick joint on the other side of the valve well.

[0028] At this point, the first toothed plate 7 stops moving downwards, and the second toothed plate 10, under the elastic force of the spring 11, remains tightly engaged with the first toothed plate 7, thus locking the position of the first toothed plate 7 and preventing the telescopic rod 2 from retracting. Simultaneously, the first locking plate 3 is restricted from axial displacement by the first limiting ring 13 on the outer side of the main rod 1, forming a stable support for the overall structure and completing the installation and positioning of the gas valve controller support structure.

[0029] When it is necessary to disassemble or adjust the device, pull the lever 12 towards the outside of the housing 6. The lever 12 drives the second toothed plate 10 to move outward in sync. During the process, the outer spring 11 is compressed. At this time, the second toothed plate 10 separates from the first toothed plate 7, and the locking state is released.

[0030] Then, pull the first toothed plate 7 upwards, which drives one end of the connecting rod 5 upwards via the second hinge seat 9. The connecting rod 5 then pulls the second locking plate 4 towards the first locking plate 3 via the first hinge seat 8, thereby pulling the two telescopic rods 2 back axially along the inner side of the main rod 1. After the telescopic rods 2 are fully retracted, the main rod 1 can be removed from the hole or brick joint in the valve well, completing the disassembly of the entire device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
