Embodiment Construction

[0024] Such as figure 2 As shown in and 3 , a connecting pipe fitting includes a pipe fitting connecting body 1 and a connecting cap 2 matched with the joint 11 of the pipe fitting connecting body 1 .

[0025] As shown in Figure 4, the pipe fitting connector 1 is preferably made of metal materials such as copper alloy and cast iron, and high-strength plastics such as PVC and ABS can also be used. 121, suitable for connecting metal pipes or corresponding plastic threaded pipes, the other end of the connector 11 has an internal thread 111, and the lower end of the internal thread 111 has a fastening port 112 with a certain slope. The inclination of the fastening port 112 is between It is at an angle of between 5° and 45° to the axial direction, preferably at an angle of 30°. An overflow hole 113 and a pipe fitting hole 114 are sequentially connected to the lower end of the fastening port 112 , and the diameter of the overflow hole 113 is slightly larger than that of the pipe f...

Abstract

The invention discloses a connecting pipe fitting, which comprises a pipe fitting connector and an attachment cap matched with the joint of the pipe fitting connector, wherein, the joint of the pipe fitting connector is provided with an internal thread, and the lower end of the internal thread is provided with a fastening port with certain slope, a pipe fitting hole and a stopping ring sequentially. The attachment cap is made of plastic materials, which has a through hole in the middle and comprises a cylinder part and a fastening head part, wherein, part or all of the outer surface of the cylinder is lathed with an external thread matched with the internal thread of the joint of the pipe fitting connector, the length of the cylinder part is greater than that of the inlet of the fastening port of the pipe fitting connector to the end face, the head of the cylinder part pushes against the slope of the fastening port of the pipe fitting connector directly. Compared with the connecting pipe fitting in the prior art, the invention has the advantages of safety, reliability and fast connection, and is particularly applied to the connection between the plastic pipes or between the plastic pipe and the metal pipe fitting.

Description

technical field [0001] The invention relates to a connecting pipe fitting, which is especially suitable for connecting with plastic pipes or between plastic pipes and metal pipe fittings. Background technique [0002] At present, plastic pipe fittings such as PE, PVC, ABS pipes, etc. have been widely used because of their good plasticity, convenient construction and cost advantages. When connecting between plastic pipes or between plastic pipes and metal pipes, construction personnel need a connecting pipe fitting with good sealing performance, easy operation and quick connection. [0003] Connection fittings for existing pipes are attached figure 1 As shown, the connecting pipe includes a pipe connecting body 7 , a connecting cap 8 matched with the joint 70 of the pipe connecting body 7 , and a collar 9 . The pipe fitting connecting body 7 is made of metal materials such as copper alloy or cast iron. The inner car of the joint 70 has an internal thread 71, and the lower e...
