Description

Technical Field

[0001] This utility model relates to the technical field of gas pressure testing devices, and in particular to a bracket for a gas pressure testing device. Background Technology

[0002] In the process of urban renewal, accelerating the replacement of gas pipelines has become a necessary means to reduce the risk of gas leaks for residents. In order to adapt to the progress of the project, it is necessary to test the pressure of gas pipelines. Existing gas pipeline pressure testing devices usually have multiple connection ports on a single pipeline, allowing multiple gas pipelines to be connected separately for batch pressure testing.

[0003] Based on feedback from operators, the pressure testing device is inconvenient to operate, mainly due to two reasons. First, the device is often placed on the ground for connection, requiring operators to adjust its position according to the interface location and connect the pipes, often necessitating a squatting or bending posture, which can lead to fatigue. Second, the connection between the device and the gas pipeline is made by tightening each pipe individually, which is inefficient and prolongs preparation time before testing. To address these operational inconveniences, a support for the gas pressure testing device is proposed. Utility Model Content

[0004] In view of this, embodiments of the present invention provide a bracket for a gas pressure testing device to solve the technical problems of existing gas pressure testing devices being too high to operate and having low efficiency in connecting gas pipelines.

[0005] An embodiment of this utility model provides a bracket for a gas pressure testing device, comprising: bottom frame; At least two support frames are provided, each support frame having a pipe support at its upper end for supporting the pressure testing device. Each support frame is detachably mounted on the base frame. Each support frame includes two insert rods, a lifting rod, a threaded sleeve, a threaded rod, and a handwheel. The lifting rod is slidably connected to the insert rod. The handwheel and the threaded rod are movably mounted on the lifting rod. The threaded sleeve is disposed inside the insert rod and threadedly connected to the threaded rod. The handwheel is connected to the threaded rod via a gear structure. Rotation of the handwheel drives the threaded rod to rotate via the gear structure. The threaded rod and the threaded sleeve are threadedly engaged, allowing the lifting rod and the insert rod to slide relative to each other.

[0006] Furthermore, the insert rod is hollow inside to provide space for accommodating the threaded rod, and the threaded sleeve is disposed at the end of the insert rod in the hollow portion; The lifting rod has a support plate inside, and the threaded rod is rotatably connected to the support plate through a bearing.

[0007] Furthermore, the gear structure includes a first bevel gear and a second bevel gear, which mesh at a 90-degree angle to each other. The first bevel gear is connected to the end of the threaded rod, and the second bevel gear is mounted on the handwheel.

[0008] Furthermore, the pressure testing device is equipped with a quick-connect plug at its connection end for connecting to a gas pipeline. The quick-connect plug includes a pressure testing connection end, a gas connection end, and a locking sleeve. The pressure testing connection end is equipped with a locking bead structure for engaging the gas connection end. The locking sleeve is movably disposed on the pressure testing connection end for locking the pressure testing connection end and the gas connection end.

[0009] Furthermore, the bead-locking structure includes multiple pressure beads, and multiple bead holes are circumferentially opened on the inner wall of the front end of the test pressure connection end. Each bead hole contains one pressure bead, and the pressure bead can move within the bead hole. A limiting groove for pressing the pressure bead is provided on the outside of the gas connection end.

[0010] Furthermore, the bead hole is configured such that the diameter of the bead hole is the same as the diameter of the pressure bead, and the end of the bead hole facing the axis of the test pressure connection end is tapered, so that the pressure bead can extend outside the bead hole but will not come out of the bead hole.

[0011] Furthermore, a groove is formed at the front end of the test pressure connection end, so that the diameter of the front end of the test pressure connection end is smaller than the diameter of the sliding connection part between the test pressure connection end and the locking sleeve. The front end of the locking sleeve has a sliding part that slides against the groove, so that an annular space is formed between the sliding part and the groove.

[0012] Furthermore, an elastic element is provided between the inner wall of the groove and the side wall of the sliding part. The elastic element pushes the locking sleeve to slide relative to the test pressure connection end, and makes the sliding part cover the bead hole.

[0013] Furthermore, a blocking ring is provided at the end of the test pressure connection, the blocking ring being located on one side of the bead hole, for limiting the sliding limit position of the locking sleeve.

[0014] Furthermore, the bottom frame is provided with a plurality of insert cylinders, each insert rod is inserted into a corresponding insert cylinder, and the insert cylinder is externally threaded with a bolt for locking the relative movement of the insert rod and the insert cylinder.

[0015] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The bracket for the gas pressure testing device of this utility model converts the rotational motion into linear sliding of the lifting rod relative to the insertion rod through a 90-degree steering transmission mechanism composed of a handwheel, bevel gear, threaded rod, and threaded sleeve. This allows for continuous adjustment of the height of the pressure testing device with one hand. The adjustment process is smooth, precise, and requires no additional tools, solving the problem of high fatigue during operation of traditional gas pressure testing devices with fixed heights. A quick-connect plug consisting of a conical bead hole, a pressure bead, a limiting groove, a locking sleeve, and an elastic element is provided between the pressure testing connection end and the gas connection end. The elastic element automatically pushes the locking sleeve to cover the bead hole, so that the pressure bead is continuously pressed into the limiting groove to form a self-locking mechanism. This achieves a one-second insertion locking and pull-out unlocking operation, greatly improving the pressure testing efficiency. The overall structure is simple and compact, easy to operate, and highly adaptable, significantly improving the efficiency of gas pipeline pressure testing. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings. The following description presents a preferred embodiment of several possible embodiments of this utility model, intended to provide a basic understanding of the utility model, but not intended to identify the key or decisive elements of the utility model or to limit the scope of protection sought.

[0019] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0020] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures. Also, it should be understood that, for ease of description, the dimensions of the various parts shown in the figures are not drawn to actual scale.

[0022] In the description of this utility model, it should be noted that the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0023] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please refer to Figure 1 and Figure 2 This utility model provides a bracket for a gas pressure testing device, including a base frame 1 and at least two support frames. Each support frame has a pipe support 5 at its upper end for supporting the pressure testing device 6. Each support frame is detachably mounted on the base frame 1, specifically by inserting a rod 3 into a cylinder 2 on the base frame 1. This facilitates transportation and storage, and improves the versatility and practicality of the bracket.

[0025] Please refer to Figures 2-3 The bottom frame 1 is provided with multiple insert cylinders 2. Each insert rod 3 is inserted into a corresponding insert cylinder 2. The insert cylinder 2 is connected to a bolt 13 on its external thread to lock the relative movement of the insert rod 3 and the insert cylinder 2.

[0026] This design makes the connection between the support frame and the base frame 1 more stable, effectively preventing the support frame from shifting or tipping over due to vibration or external forces during pressure testing, thus improving the stability and safety of the entire support system. At the same time, the detachable connection method facilitates the assembly, disassembly, and transportation of the support system, reducing maintenance costs.

[0027] Please refer to Figure 3 Each support frame is H-shaped and includes two insert rods 3, two lifting rods 4, two threaded sleeves 7, two threaded rods 9, and one handwheel 11. The insert rod 3 is hollow inside to provide space for the threaded rod 9. The threaded sleeve 7 is located at the hollow part of the insert rod 3 and is threadedly connected to the threaded rod 9. The lifting rod 4 has a support plate 8 inside, and the threaded rod 9 is rotatably connected to the support plate 8 through a bearing to ensure the stability and smoothness of the threaded rod 9 during rotation.

[0028] Furthermore, both the handwheel 11 and the threaded rod 9 are movably mounted on the lifting rod 4. The handwheel 11 is connected to the threaded rod 9 via a gear structure. The gear structure includes a first bevel gear 10 and a second bevel gear 12, which mesh at a 90-degree angle. The first bevel gear 10 is connected to the end of the threaded rod 9, and the second bevel gear 12 is mounted on the handwheel 11.

[0029] Rotating the handwheel 11 drives the second bevel gear 12 to rotate, which in turn drives the first bevel gear 10 and the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly engaged with the threaded sleeve 7, the rotational motion of the threaded rod 9 is converted into the linear sliding of the lifting rod 4 relative to the insert rod 3, thereby achieving the height adjustment of the support frame.

[0030] It should be noted that the handwheel 11 is Z-shaped, with one end passing through the lifting rod 4. The second bevel gear 12 is fixedly connected to the end of the handwheel 11 that passes through the lifting rod 4. Thus, the second bevel gear 12 can be driven to rotate synchronously by rotating the handwheel 11 outside the lifting rod 4.

[0031] This design allows operators to easily and accurately adjust the height of the pressure testing device 6 to adapt to different construction environments and operational needs, thereby improving work efficiency.

[0032] Please refer to Figure 4 and Figure 5 In this embodiment, the pressure testing device 6 is equipped with a quick-connect plug at its connection end for connecting to a gas pipeline. The quick-connect plug includes a pressure testing connection end 14, a gas connection end 15, and a locking sleeve 16. The pressure testing connection end 14 is provided with a retaining bead structure for engaging the gas connection end 15. The retaining bead structure includes multiple pressure beads 18, and multiple bead holes 17 are circumferentially formed on the inner wall of the front end of the pressure testing connection end 14. Each bead hole 17 contains a pressure bead 18, which can move within the bead hole 17.

[0033] The diameter of the bead hole 17 is the same as that of the pressure bead 18. The end of the bead hole 17 facing the axis of the test pressure connection end 14 is tapered, allowing the pressure bead 18 to extend outside the bead hole 17 without falling out. The gas connection end 15 is provided with a limiting groove 19 for pressing the pressure bead 18. When the gas connection end 15 is inserted into the test pressure connection end 14, the pressure bead 18 extends out of the bead hole 17, and the extended part of the pressure bead 18 is embedded in the limiting groove 19, realizing the insertion connection of the gas connection end 15.

[0034] Furthermore, the locking sleeve 16 is movably disposed on the pressure test connection end 14 to lock the pressure test connection end 14 and the gas connection end 15. A groove 141 is formed at the front end of the pressure test connection end 14, such that the diameter of the front end of the pressure test connection end 14 is smaller than the diameter of the sliding connection portion between the pressure test connection end 14 and the locking sleeve 16. A sliding portion 161 protrudes from the front end of the locking sleeve 16, sliding against the groove 141 to form an annular space between the sliding portion 161 and the groove 141. An elastic element 20 is provided between the inner wall of the groove 141 and the side wall of the sliding portion 161. The elastic element 20 pushes the locking sleeve 16 to slide relative to the pressure test connection end 14, and causes the sliding portion 161 to cover the bead hole 17. In the connected state, the elastic force of the elastic element 20 causes the sliding portion 161 of the locking sleeve 16 to press tightly against the pressure bead 18, preventing the pressure bead 18 from dislodging from the limiting groove 19, ensuring the firmness and sealing of the connection. When disassembly is required, simply pull the locking sleeve 16 backward to compress the elastic element 20, causing the sliding part 161 to leave the bead hole 17, and the pressure bead 18 to disengage from the limiting groove 19, thus achieving quick disassembly.

[0035] This design is not only easy to operate, but also reliable in connection, significantly improving the connection efficiency between the pressure testing device 6 and the gas pipeline, and is especially suitable for application scenarios that require frequent disassembly and assembly.

[0036] A retaining ring 21 is provided at the end of the pressure test connection 14. The retaining ring 21 is located on one side of the bead hole 17 and is used to limit the sliding limit position of the locking sleeve 16. This prevents the locking sleeve 16 from sliding excessively and disengaging from the pressure test connection 14 under the action of the elastic element 20, thus ensuring the structural integrity and safety of the quick connector.

[0037] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.
