Description

A sewage pipe connection device

Technical Field

The utility model relates to the technical field of pipeline connection, in particular to a sewage pipeline connection device.

Background Art

When sewage pipes are produced, they are generally limited in length due to processing requirements and transportation convenience. However, the length of the laid sewage pipes is not restricted. Therefore, sewage pipes need to be connected when they are laid and used.

Existing sewage pipes are generally connected by pipe joints. The connected sewage pipes are generally placed in a constructed pipe trench. However, the bottom of the pipe trench is often displaced horizontally and vertically due to factors such as uneven settlement of the soil layer, movement and changes of the earth's crust, and earthquakes, which causes the central axis of adjacent pipes to be misaligned and deflected, and the coating on the pipe is damaged. There is always an angle between the pipes, which requires that the sewage pipe connection can meet the needs of terrain changes, and also meet the bending, sealing and flexibility of the pipe connection.

However, since most existing sewage pipe connections are connected in the above-mentioned fixed manner, this method lacks proper coupling mobility when used. When bending operations are performed, the connection points of the pipes are easily damaged, resulting in leakage at the pipe connection parts, and in severe cases, rupture.

Utility Model Content

In view of this, the purpose of the utility model is to provide a sewage pipe connecting device to solve the problem that the existing sewage pipe connecting device cannot meet the bending, sealing and flexibility of the pipe connection.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Referring to Figures 1 to 4, an embodiment of the utility model provides a sewage pipe connecting device, including a first tube body 1 and a second tube body 2 connected by a connecting piece 3, the adjacent ends of the first tube body 1 and the second tube body 2 are respectively provided with connecting grooves 4, a plurality of slots 8 are formed in each connecting groove 4, rotatable balls 9 are respectively inserted in the slots 8, and these balls 9 are located between a single connecting groove 4 and a waterproof sleeve 5 connecting the first tube body 1 and the second tube body 2.

Specifically, the first tube body 1 is connected to the second tube body 2 through a connector 3. In addition, the coupling surfaces of the first tube body 1 and the second tube body 2 are respectively provided with a plurality of slots 8, and a rotatable ball 9 is respectively inserted into each slot 8, so that the sewage pipe connection device can swing flexibly, thereby enabling the first tube body 1 and the second tube body 2 to move relative to each other in a curved shape. The adjacent ends of the first tube body 1 and the second tube body 2 are respectively provided with connection grooves 4 for installing waterproof sleeves 5 to prevent water from entering the tube bodies through the coupling point between the first tube body 1 and the second tube body 2.

Therefore, the waterproof sleeve 5 can provide a waterproof seal for the coupling point of the first tube body 1 and the second tube body 2 to prevent water from entering the first tube body 1 and the second tube body 2. In addition, the ball 9 installed between the connecting grooves 4 of the first tube body 1 and the second tube body 2 can provide a larger bending angle for the sewage pipe connecting device, making the pipe more flexible, so that the sewage pipe connecting device is not easily damaged when abnormally bent, thereby extending the service life of the pipe.

In a specific embodiment, the side walls of the first tube body 1 and the second tube body 2 are respectively provided with an annular groove 15 .

In addition, a waterproof ring 14 is installed on the inner wall of the connecting member 3 , and the bottom of the waterproof ring 14 is movably connected to the annular groove 15 .

In a specific embodiment, two symmetrically arranged waterproof rings 14 are installed on the inner wall of the connecting piece 3, and these waterproof rings 14 can be inserted into the annular grooves 15 formed in the first tube body 1 and the second tube body 2 respectively to prevent water from entering through the coupling point between the connecting piece 3 and the first tube body 1 and the second tube body 2.

In a specific embodiment, a first gasket 11 is movably mounted on the end surface of the first tube body 1 , one end of the first gasket 11 is connected to the second tube body 2 , and the other end is movably connected to the side wall of the waterproof sleeve 5 .

The first gasket 11 installed between the first tube body 1 and the second tube body 2 is used to eliminate the gap between the uneven or rough coupling surfaces between the first tube body 1 and the second tube body 2 to prevent water from entering the tube body, and also provides a buffering effect on the coupling point during the pipeline installation process to avoid applying pressure that may cause damage to the first tube body 1 and the second tube body 2 during the installation process. In addition, the first gasket 11 is movably connected to the side wall of the waterproof sleeve 5, limiting the position of the first gasket 11 to only within the waterproof sleeve 5, thereby protecting it from displacement.

In a specific embodiment, a second gasket 13 is provided, which is installed between the first pipe body 1 and the second pipe body 2. The second gasket 13 installed between the first pipe body 1 and the second pipe body 2 is used to increase the wear resistance of the coupling point between the first pipe body 1 and the second pipe body 2. In addition, the second gasket 13 has a certain deformation ability and a high compressive strength, which can reduce the service life of the sewage pipe connection device, because the second gasket 13 absorbs the pressure transmitted from the inside of the sewage pipe connection device during the curve advancement of the pipeline.

Furthermore, the first tube body 1 and the second tube body 2 are respectively provided with a plurality of card slots 7, which are continuously connected to the connecting slots 4, and a plurality of card blocks 6 are inserted, the bottom of the card block 6 is movably connected to the waterproof sleeve 5, and the card block 6 inserted into the card slot 7 is connected to the waterproof sleeve 5 to fix the waterproof sleeve 5.

When in use, the first tube body 1 is connected to the second tube body 2 through the connector 3, and the coupling surfaces of the first tube body 1 and the second tube body 2 are respectively provided with a connecting groove 4, and a waterproof sleeve 5 is installed around the connecting groove 4 to prevent water from entering through the coupling point between the first tube body 1 and the second tube body 2. The coupling surfaces of the first tube body 1 and the second tube body 2 also have a plurality of slots 8, and a rotatable ball 9 is inserted in each slot. The ball 9 enables the sewage pipe connection device to bend significantly, so that the first tube body 1 and the second tube body 2 can be advanced in a curved shape. The waterproof ring 14 installed on the connector 3 can be inserted into the annular groove 15 formed in the first tube body 1 and the second tube body 2 to enhance the waterproof performance of the sewage pipe connection device. The first gasket 11 installed on the first tube body 1 and the second gasket 11 installed on the first tube body 1 are connected to the first gasket 11 installed on the first tube body 1. The two tube bodies 2 are connected to reduce the load on the first tube body 1 and the second tube body 2 during the installation process. The first gasket 11 can not only eliminate any gap between the first tube body 1 and the second tube body 2 to prevent water from entering, but also provide a buffering effect for the coupling point of the first tube body 1 and the second tube body 2 to protect the coupling surface from damage caused by pressure. The first gasket 11 is connected to the side wall of the waterproof sleeve 5, limiting the first gasket 11 only inside the waterproof sleeve 5 to prevent its possible displacement. The second gasket 13 is inserted between the first tube body 1 and the second tube body 2 to reduce the pressure transmitted from the inside of the sewage pipe connection device when the first tube body 1 and the second tube body 2 are pushed in a curve. In addition, the waterproof sleeve 5 is fixed by a clamping block 6 to prevent the waterproof sleeve 5 from falling off when the pipeline is installed.
