[0008] As a preferred embodiment of the connector for the renovation of water supply pipelines in old residential areas described in this utility model, the docking mechanism includes a connector support ring, one end of the head support ring has an external thread connector, the inner wall of the connector interface has an internal thread, and the inner wall of the connector interface is threaded to the external thread connector.

[0009] A rubber sleeve is inserted into the joint support ring, and one end of the rubber sleeve has a slit;

[0010] The rubber sleeve is fitted with two reinforcing rings, which are fixed together by bolts.

[0011] As a preferred embodiment of the connector for the renovation of water supply pipelines in old residential areas described in this utility model, the external threaded connector is fitted with a sealing ring, which is located between the connector support ring and the connector interface, and the sealing ring is in a compressed state.

[0012] As a preferred embodiment of the connector for the renovation of water supply pipelines in old residential areas described in this utility model, wherein: a butt block is welded to the outer wall of the end of the reinforcing ring, and an internal thread hole is opened on the butt block, and the adjacent butt blocks between the two reinforcing rings are fixed by bolts.

[0013] As a preferred embodiment of the connector for the renovation of water supply pipelines in old residential areas described in this utility model, the end of the rubber sleeve is integrally provided with a reinforcing strip, the reinforcing strip is provided with a through hole, and the adjacent reinforcing strips between the two rubber sleeves and the adjacent mating blocks between the two reinforcing rings are jointly fixed by bolts.

[0014] Compared with existing technologies:

[0015] By setting docking mechanisms at both ends of the connector body, the rubber sleeve in the docking mechanism has slits. When the slit end of the rubber sleeve is turned outward, the slit end of the rubber sleeve is placed on the top and bottom of the water pipe. This allows for quick modification of the water pipe without damaging it, and the modification work can be completed without removing the water pipe, thus improving the efficiency of water supply pipeline renovation in old residential areas.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] This utility model provides a connector for the renovation of water supply pipes in old residential areas. Please refer to [link / reference]. Figure 1-6 It includes a connector body 1, with connector interfaces 2 at both ends. A docking mechanism is installed on the connector interface 2, which can connect the connector body 1 to the old water supply pipe.

[0025] The connector body 1 has a third connector interface 3 in the middle, and the end of the third connector interface 3 away from the connector body 1 has a flange.

[0026] The docking mechanism includes a connector support ring 5, one end of which has an external threaded connector 51, and the inner wall of the connector interface 2 has an internal thread, with the external threaded connector 51 being threadedly connected to the inner wall of the connector interface 2.

[0027] A rubber sleeve 6 is inserted into the connector support ring 5. One end of the rubber sleeve 6 has a slit 62. Therefore, when a section of the old water pipe is cut off in the middle, the slit end of the rubber sleeve 6 can be folded to both sides. Then, the slit end of the rubber sleeve 6 can be placed on the top and bottom of the water pipe. This allows for quick modification of the water pipe without damaging it.

[0028] Two reinforcing rings 7 are fitted onto the rubber sleeve 6, and the two reinforcing rings 7 are fixed together by bolts.

[0029] A sealing ring 4 is fitted on the external threaded connector 51. The sealing ring 4 is located between the connector support ring 5 and the connector interface 2, and the sealing ring 4 is in a compressed state.

[0030] A mating block 71 is welded to the outer wall of the end of the reinforcing ring 7. The mating block 71 has an internal threaded hole 711. The adjacent mating blocks 71 of the two reinforcing rings 7 are fixed together by bolts.

[0031] The end of the rubber sleeve 6 has an integral reinforcing strip 61, and the reinforcing strip 61 has a through hole 611. The adjacent reinforcing strips 61 between the two rubber sleeves 6 and the adjacent mating blocks 71 between the two reinforcing rings 7 are fixed together by bolts.

[0032] In practical use, after cutting off a section from the middle of the old water pipe, the cut end of the rubber sleeve 6 can be folded to both sides. The cut end of the rubber sleeve 6 can then be fitted over the top and bottom of the water pipe, allowing for quick pipe modification without damage. The adjacent reinforcing strips 61 between the two rubber sleeves 6 and the adjacent mating blocks 71 between the two reinforcing rings 7 are secured together with bolts. The rubber sleeves 6 are then tightly fitted over the old water pipe, thus completing the modification of the old water pipe.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
