Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a temporary pipe connection device for water supply pipe renovation:

[0024] In this embodiment, each fastener 1 includes a bearing seat 101 connected to the fixing plate 3. Each bearing seat 101 has an inner ring connected to a threaded rod 103. The outer surface of each threaded rod 103 is threadedly connected to a threaded cylinder 102. The outer surfaces of the two sets of threaded cylinders 102 are respectively connected to the outer surfaces of two fastening rings 6. A rotating handle 4 is provided at the ends of the two sets of threaded rods 103 that are far apart from each other. The sides of the two sets of rotating handles 4 that are close to each other are respectively connected to the ends of the two sets of threaded rods 103 that are far apart from each other. Each support member 2 includes a support rod 202 connected to the connecting plate 8. A sliding cylinder 201 is slidably connected to the outer surface of each support rod 202. The outer surface of each sliding cylinder 201 is connected to the fastening ring 6. The outer surface of ring 6 is connected; specifically, by utilizing the design of the rotating handle 4 and the threaded rod 103, it is convenient for the rotating handle 4 to drive the threaded rod 103 to rotate inside the bearing seat 101, so that the threaded cylinder 102 moves on its surface following the rotation of the threaded rod 103. Then, through the connection relationship between the threaded cylinder 102 and the fastening ring 6, it is convenient to drive the fastening ring 6 closer to the pipe flange. At the same time, by utilizing the cooperation between the fastening ring 6 and the connecting ring 5, it is convenient to apply pressure to the pipe flange, thereby facilitating the connection of the pipe. In addition, with the cooperation of the support rod 202 and the slide cylinder 201, it is convenient to increase the stability of the fastening ring 6. Combined with the above cooperation, it is beneficial to strengthen the connection of the pipe and solve the problem of pipe leakage.

The ends of the two sets of positioning posts 7 that are far apart from each other are respectively connected to the sides of the two fastening rings 6 that are close to each other. A sealing gasket 9 is provided on the side of the two fastening rings 6 that is close to each other. The sides of the two sealing gaskets 9 that are close to each other are respectively connected to the left and right sides of the connecting ring 5. Specifically, the positioning posts 7 are used to facilitate the positioning of the pipe flange and prevent the pipe from rotating. The sealing gaskets 9 are used to improve the sealing effect.

[0026] Working principle: When using this temporary pipe connection device for water pipe renovation, the user first places the fastening ring 6 on the outside of the pipe, then brings the two pipes close to the sealing gasket 9. Next, the user rotates the rotating handle 4 to drive the threaded rod 103 to rotate inside the bearing seat 101. At the same time, according to the connection relationship between the threaded rod 103 and the threaded cylinder 102, the threaded cylinder 102 follows the rotation of the threaded rod 103, driving the fastening ring 6 to approach the pipe flange and pushing the positioning pin 7 into the hole opened in the flange. At the same time, the fastening ring 6 and the fixing plate 3 are used to clamp and position the pipe flange, thereby completing the pipe connection.
