As shown in fig. 1-3, the present invention provides a technical solution: the utility model provides a reducing pipe connecting device that water supply and drainage engineering used, includes reducing connecting pipe 3, and the reducing pipe is also known as reducer, is one of important water drainage pipe fitting for the connection between two kinds of different pipe diameters divide into concentric reducer and eccentric reducer again, needs more actual conditions, chooses for use different reducing pipes, leads to the staff in the maintenance work, because the condition is unclear, often need carry the reducing pipe of more specifications, and is comparatively troublesome, consequently designs this reducing connecting pipe 3. The reducing connecting pipe 3 comprises a movable reducing joint pipe 303, the movable reducing joint pipe 303 comprises a reducing intermediate joint 3302, one side of the reducing intermediate joint 3302 is fixedly connected with a reducing connecting slide rail 3305, one end of the reducing connecting slide rail 3305 is fixedly connected with a reducing connecting joint 3304, and a reducing connecting slide groove is arranged at the connecting part of the reducing connecting joint 3304 and the reducing connecting slide rail 3305. The other side of the reducing middle section 3302 is provided with a reducing connecting chute 3303, the reducing middle section 3302 is fixedly connected with a reducing increasing section 3301 through the reducing connecting chute 3303, and one end of the reducing increasing section 3301 is fixedly connected with an increasing connecting slide rail. It should be noted that in this embodiment, the number of the movable reducing pipes 303 is not necessarily three, but is determined according to the thickness difference between two pipes to be connected. In order to ensure a certain smoothness of the reducing coupling pipe 3, the movable reducing coupling pipe 303 is used as thin as possible, and the smoothness is increased by using as many movable reducing coupling pipes 303 as possible. In addition, in order to ensure the sealing performance of the reducing connecting pipe 3, the arrangement of the movable reducing joint pipes 303 is also specified in this embodiment.

In this embodiment, the movable reducing joint pipe 303 is used without distinction except for the difference in the inner and outer diameters, so that one side of each movable reducing joint pipe 303 is fixedly connected with a reducing connecting slide rail 3305, and the other end is provided with a reducing connecting slide groove 3303. When the eccentric reducing pipe needs to be used, the reducing connecting slide rail 3305 of the movable reducing pipe 303 is slid into the reducing connecting slide groove 3303 of the previous movable reducing pipe 303, and the lowest end points of the two movable reducing pipes 303 are overlapped. It should be noted that each section of the movable reducing pipe 303 has an outer wall with the same thickness, so when the lowest end points of the two sections of the movable reducing pipe 303 are overlapped, the lowest points of the inner diameters thereof are also overlapped, so that the channel formed inside the reducing connecting pipe 3 has a smooth side and a constricted side, and is used for matching the flat top or flat bottom requirement when the eccentric reducing pipe is installed. It should be noted that the dimension of each section of movable reducing pipe 303 cannot be larger than the thickness of the outer wall, otherwise, the two sections of movable reducing pipe 303 cannot shield the inner diameter after being connected together, which may cause leakage. When the concentric reducing pipe is needed, the centers of the two movable reducing pipe sections 303 are aligned in the sliding process. Because the diameter difference between the two does not exceed the thickness of the outer wall, the shielding can still be kept after the installation.

In order to fix the movable reducing joint pipe 303, the reducing connecting slide rail 3305 and the rear half section of the movable reducing joint pipe 303 are provided with corresponding fixed screw ports. It should be noted that the fixed screw ports are arranged in a group of three, the middle screw port is located at the axis of the movable reducing joint pipe 303, and the distance between the upper screw port and the lower screw port and the middle screw port does not exceed the thickness of the outer wall of the movable reducing joint pipe 303. When an eccentric reducing pipe is adopted, the reducing fixing bolt 3306 penetrates through the lower two screw ports of the three fixed screw ports of the front movable reducing joint pipe 303 and the upper two screw ports of the three fixed screw ports of the rear movable reducing joint pipe 303, so that the rear movable reducing joint pipe 303 sinks to achieve the eccentric effect, and the rest screw ports are shielded by the movable reducing joint pipe 303, so that leakage cannot be caused. When the concentric reducing pipe is used, the three screw ports are sequentially rotated in opposite directions and are fixed by the reducing fixing bolt 3306 in a threaded manner.

The reducing section 3304 one end fixedly connected with small-end connection flange, small-end connection flange one end fixedly connected with small-end connecting pipe 304, small-end connecting pipe 304 one side fixedly connected with small-end connector bolt 306, and small-end connector bolt 306 communicates to the small-end connection flange inboard. One end of the reducing enlarged joint 3301 is fixedly connected with a big end connecting convex plate 302, one side of the big end connecting convex plate 302 is fixedly connected with a big end connecting pipe 301, one end of the big end connecting convex plate 302 is fixedly connected with a big end connecting bolt 307, and the big end connecting bolt 307 is communicated to the outer side of the big end connecting pipe 301. In this embodiment, the small-head connection convex plate and the large-head connection convex plate 302 are substantially the same as the reducing connection slide rail 3305, and are connected by the fixing screw and the fixing bolt, but the large-head connection convex plate 302 and the small-head connection convex plate hopper are only connected concentrically. One end of the big end connecting pipe 301 is fixedly connected with a big end pipeline 1. One end of the small-end connecting pipe 304 is fixedly connected with a small-end pipeline 4.

When using this utility model, need according to actual conditions, according to eccentric reducing pipe or concentric reducing pipe's specification assemble reducing connecting pipe 3 to correspond at both ends and install major part connecting pipe 301 and microcephaly connecting pipe 304, install it between major part pipeline 1 and microcephaly pipeline 4 after that, thereby communicate two pipelines.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
