Description

[0002] Electric fusion pipe fittings refer to a type of plastic (polyethylene) pipe fittings that can be connected by melting through the temperature generated by electric current. When in use, electric fusion pipe fittings usually need to be fixed between the pipes to be connected, and an external power supply is connected through the electrodes on the electric fusion pipe fittings. As the resistance wire inside the pipe fittings generates heat, the pipe fittings are melted and welded to the pipes, thereby achieving a sealed connection effect between the pipes.

With the continuous rotation of the drive shaft 503, the connecting piece 201 can be pulled to the position aligned with the pipeline. 1 is put into place, and finally the fixing seat 501 and the second screw 502 are removed. In order to ensure the stability of the fixing seat 501 when the connecting piece 201 is pulled by the second screw 502, the arc-shaped concave part in the middle of the fixing seat 501 is abutted against the appropriate position of the pipe 1 through the second friction pad 604, and then the fixing sleeve 601 is connected to the traction frame 605 through the connecting groove 608. The inner side of the traction frame 605 is provided with a positioning column 606, which can locate the sliding position of the fixing sleeve 601, and then the operator needs to rotate the third screw 602 on the bottom side of the fixing seat 501 to traction the traction frame 605. 05 is driven, the traction frame 605 will pull the fixing sleeve 601 to the bottom side, so that the fixing sleeve 601 is tightly in contact with the outer side of the pipeline 1 through the first friction pad 603 on the bottom side, so as to achieve the fixation between the fixing seat 501 and the pipeline 1. At this time, the user can connect the connecting piece 201 and the pipeline 1 through the second screw 502. When connecting the second screw 502 and the first bevel gear 504, a pulling plate 701 is provided on the side of the fixing seat 501, and the end of the second screw 502 that passes through the connecting ear 401 continues to pass through the corresponding end of the pulling plate 701. A tooth block is provided on the inner side of the pulling plate 701 703, at this time, the pulling plate 701 is slid. Due to the inclined tooth structure on the side of the tooth block 703, the second screw rod 502 can slide under the condition of traction. After the pulling plate 701 slides out a proper distance, the pulling plate 701 is released. Under the traction of the fifth spring 702, the tooth block 703 will drive the second screw rod 502 to slide toward the fixed seat 501 as the pulling plate 701 slides, until the end of the second screw rod 502 conflicts with the middle of the first bevel gear 504. At this time, the user can directly rotate the driving shaft 503 to complete the threaded connection between the second screw rod 502 and the first bevel gear 504, which is convenient for operation.
