Description

Technical Field

[0001] This utility model relates to the field of gas meter connectors, specifically to a guide positioning sleeve for quick connection of gas meter connectors. Background Technology

[0002] Gas meter connectors are crucial components connecting gas pipelines and gas meters, primarily ensuring the safe and stable delivery of gas to users. Gas meter connectors are typically made of copper (such as brass), offering excellent sealing and corrosion resistance, and are compatible with media such as natural gas and liquefied petroleum gas. Their thread design conforms to international standards (such as ISO 228), ensuring a tight connection with the gas pipeline and preventing leaks. Regular checks are necessary to ensure the connectors are not loose or damaged, preventing gas leaks caused by aging or vibration. If any abnormalities are found, contact a professional immediately for repair. When gas meter connectors are connected, there is a lack of a dedicated guide and positioning structure, which requires time to center them. Furthermore, misalignment is prone to occur during installation, which can damage the threads at the contact point, affecting the sealing effect of the connection and the service life of the interface. This is a shortcoming. Utility Model Content

[0003] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a guide positioning sleeve for quick docking of gas meter connectors, which has the characteristics of guiding positioning and assisting centering docking.

[0004] (II) Technical Solution To solve the above technical problems, this utility model provides a guide positioning sleeve for quick docking of gas meter connectors. The clamping mechanism includes an upper clamping ring and a lower clamping ring arranged symmetrically. The end faces of the two clamping rings are respectively formed with upper and lower bolt plates with bolt holes. Locking bolts are screwed into the bolt holes of the two clamping rings. The upper clamping ring and the lower clamping ring clamp an annular cavity, and limit bolts are screwed into the opposing screw holes of the two rings respectively. One end of the upper clamping ring is formed with a protruding guide ring plate, and one end of the lower clamping ring is formed with a protruding support ring plate. The guide ring plate and the support ring plate close together to form an annular cavity.

[0005] Preferably, the upper clamping ring and the lower clamping ring have the same structure but are installed in opposite directions. The gas meter connector to be assembled is clamped between the two, and the annular cavity clamped by the two is on the same axis as the gas meter connector.

[0006] Preferably, the screw holes on the upper and lower clamping rings are located at the ends, and a clamping gap is left between the inner wall of the other end and the gas meter connector.

[0007] Preferably, the limiting bolt is threadedly engaged with the upper clamping ring or the lower clamping ring, and one end of the limiting bolt that penetrates the inner cavity and abuts against the gas meter connector is a rubber component.

[0008] Preferably, the guide ring plate is a short ring, the support ring plate is a long ring, and the combined annular cavity is semi-open.

[0009] Preferably, the upper clamping ring and the guide ring plate are an integral structure, and the lower clamping ring and the support ring plate are an integral structure, with the same inner diameter.

[0010] The above-mentioned technical solution of this utility model has the following beneficial technical effects: Since the combined structure of the upper and lower clamping rings is sleeved on the outside of the gas meter connector as a centering structure, the annular cavity formed by the two is semi-open. The other connector to be connected can be directly inserted by the combined structure of the semi-open guide ring plate and the support ring plate. The support ring plate directly supports the other connector and screws it into the other connector along the guide ring plate. The connection can be directly performed without centering. Moreover, due to the enclosure and limitation of the two during the connection process, misalignment and damage to the threads can be prevented during the connection. During the screwing process, the upper and lower clamping rings can also surround and limit the outer wall of the other connector, improving the stability of the connection.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0014] like Figure 1-5As shown, the present invention proposes a guide positioning sleeve for quick docking of gas meter connectors. The clamping mechanism includes an upper clamping ring 11 and a lower clamping ring 13 arranged symmetrically. The end faces of the two are respectively formed with an upper bolt plate 12 and a lower bolt plate 14 with bolt holes. A locking bolt 15 is screwed into the bolt holes of the two. An annular cavity is held between the upper clamping ring 11 and the lower clamping ring 13, and limit bolts 2 are screwed into the opposing screw holes of the two respectively. One end of the upper clamping ring 11 is formed with a protruding guide ring plate 3, and one end of the lower clamping ring 13 is formed with a protruding support ring plate 4. The guide ring plate 3 and the support ring plate 4 close together to form an annular cavity.

[0015] It should be noted that the upper clamping ring 11 and the lower clamping ring 13 have the same structure but are installed in opposite directions. The gas meter connector to be assembled is clamped between the two. The annular cavity clamped by the two is on the same axis as the gas meter connector. First, the upper clamping ring 11 and the lower clamping ring 13 are fitted outside the gas meter connector. The external annular cavity is used to assist in centering before docking.

[0016] In this embodiment, the guide ring plate 3 is a short ring and the support ring plate 4 is a long ring. Since the combined structure of the upper and lower clamping rings is sleeved on the outside of the gas meter connector as a centering structure, the annular cavity formed by the two is semi-open. The other connector to be connected can be directly inserted by the semi-open guide ring plate 3 and support ring plate 4 combined structure. The support ring plate 4 directly supports the other connector and screws it into the other connector along the guide ring plate 3. The connection can be directly performed without centering. Moreover, due to the surrounding and limiting of the two during the connection process, misalignment and damage to the threads can be prevented during the connection. During the screwing process, the upper and lower clamping rings can also surround and limit the outer wall of the other connector, improving the stability of the connection.

[0017] In one embodiment, the upper and lower clamping ring combination structure acts as a detachable external limiting structure, providing external limiting guidance during use. During disassembly, the bolt 15 is removed from the bolt holes attached to the upper bolt plate 12 and the lower bolt plate 14, and the combination structure can be disassembled after the locking between the two is removed, making it reusable.

[0018] To facilitate the placement of the connector within the combined structure of the guide ring plate 3 and the support ring plate 4, the combined annular cavity is further designed to be semi-open, with the opening of the guide ring plate 3 used to insert the connector and the support ring plate 4 serving as a support structure.

[0019] It is understandable that the upper clamping ring 11 and the guide ring plate 3 are an integral structure, and the lower clamping ring 13 and the support ring plate 4 are an integral structure. The inner diameters of the two are the same. After the upper and lower clamping rings are centered, the joint does not need to be centered again during its movement along the guide ring plate 3 and the support ring plate 4.

[0020] As an example of centering the upper and lower clamping rings: the limiting bolt 2 is threadedly engaged with the upper clamping ring 11 or the lower clamping ring 13. The end of the limiting bolt 2 that penetrates into the inner cavity and abuts against the gas meter connector is a rubber component. Through the screwing movement of the limiting bolt 2 in the two screw holes, the two limiting bolts 2 clamp the gas meter connector at the same central axis position.

[0021] The screw holes on the upper clamping ring 11 and the lower clamping ring 13 are located at the ends, and a clamping gap is left between the inner wall of the other end and the gas meter connector. During the docking process, the clamping gap is used for the insertion of the other connector.

[0022] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
