However, since the position of the rotating shaft of the motor is not fixed after each stop, but the position of the threaded core in the saddle bypass is fixed, this leads to the failure of the core-pulling fixture and the threaded core to cooperate smoothly again, resulting in the failure of the motor to start normally core pulling

Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 , figure 2 As shown, a saddle-type bypass core-pulling transmission connector of the present invention includes an adjustment sleeve 11 , a stop pin 12 and a connecting sleeve 13 , and in this embodiment, there are two stop pins 12 . One end of the adjusting sleeve 11 is provided with a first mounting hole 111 (square hole) matched with the threaded core, and the other end of the adjusting sleeve 11 is provided with a connecting hole 112 (round hole). Two arc grooves 113 are provided at different positions on the surface, the width of the arc grooves 113 is slightly larger than the outer diameter of the stop pin 12, and the arc of the arc grooves 113 is at least 90°. One end of the connecting shaft sleeve 13 is provided with a second mounting hole 131 (round hole plus keyway) matched with the output shaft of...

Abstract
The invention relates to the technical field of pipe fitting production, and technically aims to provide a saddle bypass core-pulling transmission connector that is convenient for connection of a threaded core and a core-pulling fixture so as to facilitate normal start of a motor to conduct core pulling. The saddle bypass core-pulling transmission connector comprises an adjustment sleeve, stop pins and a connection shaft sleeve. One end of the adjustment sleeve is provided with a first mounting hole fitting the threaded core, and the other end is provided with a connecting hole. The outer surface of the adjustment sleeve is provided with arc grooves. One end of the connection shaft sleeve is equipped with a second mounting hole fitting a motor output shaft, and the other end is provided with a connecting shaft fitting the connecting hole. Through holes are disposed at a connecting shaft position corresponding to the arc grooves. The stop pins are inserted into the through holes and can rotate in the arc grooves. During use of the saddle bypass core-pulling transmission connector provided in the invention, no matter where the output shaft on the motor stops, smooth fitting of the core-pulling fixture and the threaded core and normal core pulling operation can be realized by adjusting the position of the adjustment sleeve.
Description
technical field [0001] The invention relates to the technical field of pipe fitting production, and more specifically, to a saddle-type bypass core-pulling transmission connector. Background technique [0002] In the prior art, the saddle-type bypass (such as PE electrofusion saddle-type bypass) generally has many threads inside, and the threads must be injection-molded through a thread core. Due to the many internal threads of the saddle bypass, it is usually taken out of the mold together with the threaded core during demoulding, and then the core-pulling fixture fixed on the motor shaft is driven to rotate by starting the motor, thereby pulling out the threaded core. However, since the position of the rotating shaft of the motor is not fixed after each stop, but the position of the threaded core in the saddle bypass is fixed, this leads to the failure of the core-pulling fixture and the threaded core to cooperate smoothly again, resulting in the failure of the motor to st...
