Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection devices, in particular to a water heating pipeline connector. Background Technique

[0002] A water heating pipeline system includes pipelines for heating and water supply and their connecting components. These pipelines are usually used to transport hot water, cold water or steam to ensure the normal operation of the heating and water supply systems in buildings. The connector is used to tightly connect two sections of pipelines.

[0003] The existing Chinese patent document CN221004146U discloses a metal connector for building water heating pipelines, including a connecting sleeve. The inside of the connecting sleeve is threadedly connected with water heating pipes. A middle piece is squeezed between the connecting sleeves. Sealing rings are fixedly connected to both sides inside the middle piece. Threaded sleeves are threadedly connected to both sides of the outer surface of the middle piece. An external threaded pipe is fixedly connected to the outer surface of the connecting sleeve on one side of the threaded sleeve. An upper ring sleeve and a lower ring sleeve are symmetrically attached to the outer surface of the middle piece between the threaded sleeves. By threadedly connecting the connecting sleeve with the water heating pipeline and inserting it into the inside of the middle piece to form a good sealing effect, and then rotating the threaded sleeve to be partially threadedly connected to the outer surface of the external threaded pipe, the two pipelines can be quickly and conveniently connected. At the same time, the upper ring sleeve and the lower ring sleeve are used to limit the threaded sleeve to prevent the threaded sleeve from loosening and rotating back, ensuring the stability of the overall connection. However, this connector still has deficiencies: the structural specifications of its iron ring and sealing ring are fixed, and they are used to wrap and seal the inner side and end face of the water heating pipeline, resulting in limited use range of the connector and inability to adapt to the connection of water heating pipelines with the same outer diameter but different wall thicknesses. When the wall thicknesses of the water heating pipelines to be connected are different, the connector cannot be used, reducing the versatility of the connector. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water heating pipeline connector to solve the problem that in the above-mentioned water heating pipeline connector, the structural specifications of its iron ring and sealing ring are fixed, and they are used to wrap and seal the inner side and end face of the water heating pipeline, resulting in limited use range of the connector and inability to adapt to the connection of water heating pipelines with the same outer diameter but different wall thicknesses. When the wall thicknesses of the water heating pipelines to be connected are different, the connector cannot be used, reducing the versatility of the connector.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water heating pipe connector, comprising: a threaded sleeve 1, a threaded sleeve 2, a water heating pipe 1 and a water heating pipe 2, the threaded sleeve 1 is provided with a sealing ring groove inside, a rubber ring gasket is embedded in the sealing ring groove, a fixed sleeve is provided with a limit ring 1 at one end of the outer side of the threaded sleeve 1, a sealing protrusion ring is fixedly connected to one end of the threaded sleeve 1, a limit ring 2 is fixedly provided at one end of the outer side of the threaded sleeve 2, a sealing groove ring is fixedly connected to one end of the threaded sleeve 2, a clamping sleeve at the connection between the threaded sleeve 1 and the threaded sleeve 2 is provided with a clamping hoop 1 and a clamping hoop 2 which are hinged to each other, one end of the clamping hoop 1 is fixedly connected with a limit frame provided with a limit groove, one end of the clamping hoop 2 is fixedly connected with a limit plug, and one end of the limit plug is provided with a spring groove with a connecting spring and a limit cover arranged inside.

[0006] As a further solution of the utility model: the threaded sleeve 1 and the threaded sleeve 2 are respectively screwed together with the outer sides of the opposite ends of the water heating pipe 1 and the water heating pipe 2 through connecting threads, and the threaded sleeve 1 and the threaded sleeve 2 are both sleeve structures with shrinkage limit rings arranged at the opposite ends.

[0007] As a further solution of the utility model: the sealing ring groove and the rubber ring gasket are both L-shaped in cross-section and the protruding end is located at the ring groove and ring gasket structure arranged on the outer ring, and the rubber ring gasket slightly protrudes from the sealing ring groove toward the water heating pipe.

[0008] As a further solution of the utility model: the interior of the second threaded sleeve is provided with sealing ring grooves and rubber ring gasket structures of the same number and specifications as those of the first threaded sleeve, and the water-passing sides of the shrinkage limit rings at the opposite ends of the two are provided with smooth chamfers.

[0009] As a further solution of the utility model: the specifications of the sealing bump ring and the sealing groove ring are matched and a sealing ring gasket is provided at the connection. When the sealing bump ring and the sealing groove ring are plugged into each other, there is still a certain gap at the base of the two to improve the connection tightness of the bump and the groove.

In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "set" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. The following will illustrate the embodiments according to the overall structure of the present utility model.

[0023] Refer to Figures 1 to 6 , in the embodiment of the present utility model, a plumbing pipe connector includes: a first threaded sleeve 1, a second threaded sleeve 2, a first plumbing pipe 3, and a second plumbing pipe 4. A sealing ring groove 5 is formed inside the first threaded sleeve 1, and a rubber ring gasket 6 is embedded inside the sealing ring groove 5. A first limiting ring 7 is fixedly sleeved at one end of the outer side of the first threaded sleeve 1. A sealing convex ring 8 is fixedly connected to one end of the first threaded sleeve 1. A second limiting ring 9 is fixedly sleeved at one end of the outer side of the second threaded sleeve 2. A sealing groove ring 10 is fixedly connected to one end of the second threaded sleeve 2. A first clamping hoop 11 and a second clamping hoop 12 which are hinged to each other are clamped and sleeved at the connection of the first threaded sleeve 1 and the second threaded sleeve 2. A limiting frame 13 provided with a limiting groove 14 is fixedly connected to one end of the first clamping hoop 11. A limiting insert 15 is fixedly connected to one end of the second clamping hoop 12. A spring groove 16 with a connecting spring 17 and a limiting cover 18 arranged inside is formed at one end of the limiting insert 15.

[0024] Refer to Figure 1 and Figure 2, the first threaded sleeve 1 and the second threaded sleeve 2 are respectively screwed and connected to the outer sides of the opposite ends of the first plumbing pipe 3 and the second plumbing pipe 4 through connecting threads. Both the first threaded sleeve 1 and the second threaded sleeve 2 are sleeve structures with shrinkage limiting rings provided at their opposite ends.

[0025] With the above solution: when the first threaded sleeve 1 and the second threaded sleeve 2 are tightened with the first plumbing pipe 3 and the second plumbing pipe 4, the shrinkage limiting rings provided inside abut against the end faces of the plumbing pipes. Moreover, the structure in which the split connectors are respectively screwed is more convenient than the integral structure and avoids the trouble of rotating the plumbing pipe body.

[0026] Refer to Figure 3 and Figure 4 , both the sealing ring groove 5 and the rubber ring gasket 6 are ring groove and gasket structures with an L-shaped cross-section and the protruding ends located on the outer ring. Moreover, the part of the rubber ring gasket 6 facing the first plumbing pipe 3 slightly protrudes from the sealing ring groove 5.

[0027] With the above solution: the L-shaped rubber ring gasket 6 wraps the outer side port of the plumbing pipe, and the slightly protruding structure increases the tightness of the wrapped connection. Compared with the structure that wraps the inner side port, it can adapt to plumbing pipes with the same outer diameter but different wall thicknesses, improving the versatility of the connector.

[0028] Refer to Figures 1 to 4 , the second threaded sleeve 2 is internally provided with the same number and specifications of sealing ring grooves 5 and rubber ring gasket 6 structures as the first threaded sleeve 1, and chamfers with smooth lines are provided on the water passing sides of the shrinkage limiting rings at their opposite ends.

[0029] With the above solution: the rubber ring gasket 6 provides a sealed connection, and the chamfer setting of the shrinkage limiting ring avoids excessive influence on the water flow situation inside the plumbing pipe.

[0030] Refer to Figure 4 , the sealing convex ring 8 and the sealing groove ring 10 are of matching specifications and a sealing ring gasket is provided at the connection. When the sealing convex ring 8 and the sealing groove ring 10 are inserted into each other, there is still a certain gap at their bases to improve the connection tightness between the convex and the groove.

[0031] With the above solution: the structure in which the sealing convex ring 8 and the sealing groove ring 10 are inserted into each other and tightly abut against each other and the sealing ring gasket structure provided at the connection are convenient for ensuring the sealing performance when the first threaded sleeve 1 and the threaded sleeve 2 are connected.

[0032] Refer to Figure 5 and Figure 6 , the first clamping hoop 11 and the second clamping hoop 12 connect the first threaded sleeve 1 and the second threaded sleeve 2 by closing and clamping the first limiting ring 7 and the second limiting ring 9. The limiting frame 13 is fixedly connected to both sides of the first clamping hoop 11, the limiting cover 18 is elastically connected to the inside of the spring groove 16 through the connecting spring 17, and the limiting groove 14 and the limiting cover 18 are of matching specifications and positions.

[0033] By adopting the above scheme: the clamping hoop 11 and the clamping hoop 2 12 quickly tighten the threaded sleeve 1 and the threaded sleeve 2 2 by closing the clamping limit ring 1 7 and the limit ring 2 9, and the limit cover 18 elastically connected to the inside of the spring groove 16 is engaged with the limit groove 14 to quickly fix the closed state of the clamping hoop 11 and the clamping hoop 2 12, which improves the disassembly and replacement speed compared with the connection method of the threaded barrel and the bolt.

[0034] The working principle of the utility model is as follows: when in use, the threaded sleeve 1 and the threaded sleeve 2 are respectively screwed together and connected to the outer sides of the opposite ends of the water heating pipe 1 3 and the water heating pipe 2 4 through the connecting threads, the rubber ring gasket 6 is embedded in the sealing ring groove 5, and the rubber ring gasket 6 slightly protrudes from the sealing ring groove 5. In the screw-tight state, the rubber ring gasket 6 of the L-shaped structure presses the outer side surface of the water heating pipe to play a sealing role. The sealing structure wrapped around the outer side surface can flexibly adapt to the connection requirements of water heating pipes with the same outer diameter but different wall thicknesses relative to the sealing structure wrapped around the inner side surface, has a wider range of applications, improves the versatility of the connector, and is generally A limiting ring 17 and a limiting ring 29 are provided to connect two sets of threaded sleeves through the clamping hoop 11 and the clamping hoop 2 12, so that the relatively arranged sealing protrusion ring 8 and the sealing groove ring 10 are plugged into each other and sealed. The relative threaded tube connection and bolt connection are more convenient for quick disassembly and assembly. When the clamping hoop 11 and the clamping hoop 2 12 are closed, the end of the limiting insert 15 is inserted into the limiting frame 13, and the limiting cover 18 elastically connected to the spring groove 16 through the connecting spring 17 is then clamped into the limiting groove 14. The above-mentioned overall structure is easy to connect and disassemble, which is beneficial to improving the disassembly and assembly speed and the replacement and installation efficiency.

[0035] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
