Description

Technical Field

[0001] This utility model relates to the field of pipe connectors, and in particular to a pipe tee connector that is easy to adjust the angle. Background Technology

[0002] Pipe tees are a type of pipe fitting used to connect three pipes together, enabling them to communicate with each other. They are a common type of pipe fitting used in daily life and are widely used in various fields due to their function. When connecting pipes with existing tee connectors, their function is simple and the connection is convenient. However, the pipe angles of existing tee connectors are generally fixed, which makes it inconvenient to adjust them according to the situation. Utility Model Content

[0003] The purpose of this invention is to provide a pipe tee fitting that is easy to adjust the angle of, thus solving the problem that existing pipe tee fittings cannot adjust the pipe connection angle.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A pipe tee fitting with adjustable angle includes a tee fitting body, the tee fitting body including a main pipe and a branch pipe, the branch pipe being connected to the middle of the main pipe via a corrugated pipe, an upper telescopic support rod and a lower telescopic support rod being provided above and below the corrugated pipe respectively, the upper end and lower end of the upper telescopic support rod being connected to the outer wall of the main pipe and the top surface of the branch pipe respectively via a rotating support, and the upper end and lower end of the lower telescopic support rod being connected to the bottom surface of the branch pipe and the outer wall of the main pipe respectively via a rotating support.

[0006] In this solution, corrugated pipes are used to connect the main pipe and the branch pipes. This allows for adjustment of the branch pipe connection angle. After adjustment, the upper and lower telescopic support rods are used to position the angle, resulting in better adaptability.

[0007] As a further preferred embodiment of this utility model, both the upper telescopic support rod and the lower telescopic support rod include a sleeve rod, a plug rod, and a rotating joint. One end of the plug rod is threadedly connected to the sleeve rod, and the other end of the plug rod is connected to the rotating support through the rotating joint.

[0008] The lengths of the upper and lower telescopic support rods can be adjusted by rotating the plug rod. To avoid affecting the rotating support when rotating the plug rod, a rotary joint is used to connect the plug rod and the rotating support.

[0009] As a further preferred embodiment of this utility model, the tee head of the tee connector body is connected to a pipe connector via a telescopic corrugated pipe, and a telescopic outer protective shell is also provided at the tee head of the tee connector body, with the other end of the telescopic outer protective shell being inserted into the pipe connector.

[0010] A pipe connector is installed at the tee head of the tee fitting body, and the pipe connector is connected to the tee fitting body through a telescopic corrugated pipe. In this way, when a small error occurs in the measurement, the expansion space of the corrugated pipe can play an adaptive adjustment role, so that the tee fitting body can adapt to various errors without replacing the pipe, saving installation costs. In addition, due to the fragility of the corrugated pipe, a telescopic outer protective shell is also installed outside the corrugated pipe, which is connected to the tee head of the tee fitting body. This shell can protect the corrugated pipe and can also adjust the length of the protection, making it highly adaptable.

[0011] As a further preferred embodiment of this utility model, the wall of the telescopic corrugated pipe includes a heat insulation layer, a metal wire layer and an anti-corrosion layer arranged sequentially from the inside to the outside.

[0012] The inner side is insulated, and the metal wire layer can protect it from being cut, while the anti-corrosion layer can prevent corrosion.

[0013] As a further preferred embodiment of this utility model, the outer wall of the pipe connector is provided with external threads for connection.

[0014] The pipe is connected to the pipe fitting via an internal thread on the inner wall of one end of the pipe.

[0015] As a further preferred embodiment of the present invention, the outer wall of the pipe connector is further provided with a sealing ring. The sealing ring is set tightly against the pipe connector. The sealing ring includes a ring body and an edge limiting part. The ring body is set around the outer wall of the pipe connector, and the edge limiting part is set along the edge of the ring body. The edge limiting part is located on the side of the outer wall of the pipe connector where the external thread is provided.

[0016] Sealing rings can provide a seal after pipe connections are made, thus enhancing the sealing performance.

[0017] As a further preferred embodiment of this utility model, a sealing strip is provided in the groove formed by the ring body, the edge limiting part, and the outer wall of the pipe connector.

[0018] As a further preferred embodiment of this utility model, the pipe connector has a plug groove at one end facing the tee connector body. The plug groove is adapted to the plug block at one end of the telescopic outer protective shell. The surface of the pipe connector is uniformly provided with threaded holes communicating with the plug groove. The threaded holes are set perpendicular to the plug groove.

[0019] After connecting the pipes, adjust the length of the telescopic outer protective shell so that the plug at one end is inserted into the plug groove of the pipe connector. Then, use bolts inserted into the threaded holes to press and rub the plug to fix it in place. This will ensure that the telescopic outer protective shell does not retract.

[0020] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0021] 1. A pipe connector is installed at the tee head of the tee fitting body, and the pipe connector is connected to the tee fitting body through a telescopic corrugated pipe. In this way, when there is a small error in the measurement, the expansion space of the corrugated pipe can play an adaptive adjustment role, so that the tee fitting body can adapt to various errors without replacing the pipe, saving installation costs. In addition, due to the fragility of the corrugated pipe, a telescopic outer protective shell is also installed outside the corrugated pipe, which is connected to the tee head of the tee fitting body. It can protect the corrugated pipe and can also adjust the length of the protection, which has good adaptability.

[0022] 2. The inner side is insulated, and the metal wire layer can protect it from being cut, while the anti-corrosion layer can prevent corrosion.

[0023] 3. The sealing ring can play a sealing role after the pipe is connected, thus enhancing the sealing performance.

[0024] 4. After connecting the pipes, adjust the length of the telescopic outer protective shell so that the plug at one end is inserted into the plug groove of the pipe connector. Then, use bolts inserted into the threaded holes to press and rub the plug to fix it. This will ensure that the telescopic outer protective shell does not retract. Attached Figure Description
