[0002] Reducers, also known as reducers, are one of the important drainage pipe fittings. They are used to connect two pipes of different diameters. They are divided into concentric reducers and eccentric reducers. Different reducers need to be selected according to actual conditions.

[0003] Pipes are usually installed independently, which makes it inconvenient to connect reducers. However, if conditions permit, coaxial installation of different pipes can produce special effects. Utility Model Content

[0004] The purpose of the utility model is to provide a coaxial installation device for pipes of different diameters to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a coaxial installation device for pipes of different diameters, comprising a first pipe and a second pipe;

[0006] The pipe is connected to the second pipe in a sleeve manner, and an inner support ring is inserted between the first pipe and the second pipe;

[0007] The same inner support ring type joint is provided between two adjacent first pipes and between two adjacent second pipes.

[0008] Preferably, the inner support ring is formed in one piece.

[0009] Preferably, the inner support ring type joint includes a connecting plate and an outer clamping tube and an inner clamping tube fixedly sleeved on the connecting plate, and the outer clamping tube is sleeved on the outside of the connecting plate, the pipe one is sleeved in the outer clamping tube, and the pipe two is sleeved in the inner clamping tube.

[0010] Preferably, the inner support ring comprises an outer tube and an inner tube, the inner tube is sleeved inside the outer tube, and a plurality of connecting pieces are connected between the outer tube and the inner tube at equal intervals.

[0011] Preferably, there are multiple inner support rings, and the multiple inner support rings are arranged at equal intervals between pipe one and pipe two.

[0012] Preferably, the inner support ring type joint adopts an integral molding process.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The device has a simple structure. Both the inner support ring and the outer support ring are hollow pipe fittings composed of an inner (short) tube, an outer (short) tube and a connecting piece. Both can be produced by an integrated molding process, and have the advantages of simple structure and low cost.

[0015] 2. The installation and construction are simple and convenient. When coaxially installing different-diameter pipes, it is only necessary to place a certain number of inner support rings between the two pipes. When connecting the pipes, it is only necessary to connect the large pipe and the small pipe to the inner support ring joint at the same time, which is basically the same as the ordinary pipe connection method.

[0016] 3. Save space, increase efficiency and reduce costs, and have good application prospects. Coaxial installation of two different-diameter pipes can save building space, improve pipeline installation efficiency, and reduce the overall cost of the project. In addition, the application of coaxial reducers in specific scenarios can achieve special effects. Its uses can be continuously explored and it has good application prospects.
