Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe connection technology, and in particular to a reducing pipe connection structure. Background Technology
[0002] A reducer is a type of pipe fitting used at pipe diameter changes. It is one of the chemical pipe fittings used to connect two pipes of different diameters. The most common reducer is the reducing fitting, which is further divided into concentric reducers and eccentric reducers. When the flow rate of the fluid in the pipeline changes, such as increasing or decreasing, and the required flow velocity does not change significantly, a reducer is required.
[0003] However, existing reducer connection structures have some problems in use. They are relatively complicated to use, and the sealing effect may be poor after the pipe is connected to the reducer, which may lead to leakage. At the same time, they are not convenient for filtering impurities in the water flow inside the pipe, and the filtration equipment is not easy to clean, which reduces the applicability of reducers. Utility Model Content
[0004] The purpose of this invention is to provide a reducing pipe connection structure to solve the problems mentioned in the background art.
[0005] The technical solution of this utility model is a reducing pipe connection structure, including a telescopic reducing pipe body. Both ends of the telescopic reducing pipe body are provided with pipes. Both ends of the telescopic reducing pipe body are provided with a first annular groove. A second magnetic ring is fixedly connected in each of the first annular grooves. The end of the pipe near the telescopic reducing pipe body is provided with a second annular groove. A first magnetic ring is fixedly connected in each of the second annular grooves. The first magnetic ring and the second magnetic ring are fitted together.
[0006] In one embodiment, L-shaped rings are fixedly connected to the outer edges of the telescopic reducer body near both the left and right sides. Two elastic rods are fixedly connected to the side of the L-shaped ring away from the center of the telescopic reducer body. Each L-shaped ring is provided with a sealing ring. The sealing rings are together sleeved on the telescopic reducer body and the outer edge of the pipe. The end of the elastic rod away from the L-shaped ring is fixedly connected to the side of the sealing ring.
[0007] In one embodiment, a fixing rod is fixedly connected to both the top and bottom of the pipe, and an arc-shaped plate is fixedly connected to the end of the fixing rod away from the pipe. The arc-shaped plate is sleeved on the outer edge of the adjacent L-shaped ring.
[0008] In one embodiment, the arc-shaped plate has first threaded holes on both the front and rear sides, and the L-shaped ring has two second threaded holes on both the front and rear sides. Bolts are threaded into the first threaded holes, and one end of the bolts is threaded into the adjacent second threaded holes.
[0009] In one embodiment, a vertical plate is provided at the center of the inner cavity of the telescopic reducer body, and the top and bottom of the vertical plate are fixedly connected to the top and bottom of the inner cavity of the telescopic reducer body.
[0010] In one embodiment, a through hole is provided at the center of the vertical plate, and a horizontal bar is provided through the through hole. Filter plates are fixedly connected to both ends of the horizontal bar, and the two filter plates are located in the inner cavity of the telescopic reducer.
[0011] In one embodiment, the two filter plates are arranged side by side.
[0012] The beneficial effects provided by this utility model are:
[0013] By cooperating with the telescopic reducer body, filter plates, L-shaped rings, and sealing rings, the telescopic reducer body can be placed between two pipes. The length of the telescopic reducer body can be adjusted according to the distance between the two pipes. The second magnetic rings at both ends of the telescopic reducer body attract the first magnetic ring on the pipe, thus initially installing the telescopic reducer body. The L-shaped ring is placed on the pipe surface, and the sealing ring moves to the surface of the telescopic reducer body and the pipe, sealing the telescopic reducer body and the pipe to prevent leakage. The bolts are then turned onto the arc plate and L-shaped ring to further install the telescopic reducer body. The filter plates on both sides of the inner cavity of the telescopic reducer body can perform double filtration of the water flow. After the telescopic reducer body is disassembled, the filter plates can be moved to the left or right to clean the two filter plates. Attached Figure Description

[0020] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, a reducing pipe connection structure includes a telescopic reducing pipe body 1. Pipes 2 are provided at both ends of the telescopic reducing pipe body 1. First annular grooves are opened at both ends of the telescopic reducing pipe body 1. Second magnetic rings 10 are fixedly connected to each of the first annular grooves. A second annular groove is opened at the end of each pipe 2 near the telescopic reducing pipe body 1. A first magnetic ring 9 is fixedly connected to each of the second annular grooves. The first magnetic ring 9 and the second magnetic ring 10 are fitted together. L-shaped rings 6 are fixedly connected to the outer edges of the telescopic reducing pipe body 1 near both the left and right sides. Two elastic rods 7 are fixedly connected to the side of each L-shaped ring 6 away from the center of the telescopic reducing pipe body 1. Sealing rings 8 are provided inside each L-shaped ring 6. The sealing rings 8 are collectively sleeved on the outer edges of the telescopic reducing pipe body 1 and the pipe 2. The end of each elastic rod 7 away from the L-shaped ring 6 is fixedly connected to one side of the sealing ring 8.
[0021] Fixed rods 11 are fixedly connected to the top and bottom of pipe 2. An arc-shaped plate 12 is fixedly connected to the end of the fixed rod 11 away from pipe 2. The arc-shaped plate 12 is sleeved on the outer edge of the adjacent L-shaped ring 6. The arc-shaped plate 12 has first threaded holes on both the front and rear sides. The L-shaped ring 6 has two second threaded holes on both the front and rear sides. Bolts 13 are threaded into the first threaded holes.

The two filter plates 5 are located in the inner cavity of the telescopic reducer body 1 and are arranged left and right.
[0022] Working principle: The telescopic reducer body 1 is placed between two pipes 2. The length of the telescopic reducer body 1 is adjusted according to the distance between the two pipes 2. The second magnetic rings 10 at both ends of the telescopic reducer body 1 attract each other to the first magnetic rings 9 on the pipes 2, thus initially installing the telescopic reducer body 1. The L-shaped ring 6 is fitted onto the surface of the pipe 2. The sealing ring 8 moves to the surface of the telescopic reducer body 1 and the pipe 2, thus sealing the telescopic reducer body 1 and the pipe 2 to prevent leakage. The bolt 13 is rotated onto the arc plate 12 and the L-shaped ring 6, thus further installing the telescopic reducer body 1. The filter plates 5 on the left and right sides of the inner cavity of the telescopic reducer body 1 can perform double filtration of the water flow. After the telescopic reducer body 1 is disassembled, the filter plates 5 can be moved to the left or right to clean the two filter plates 5.
