Working principle of automatic telescopic reel:
The automatic telescopic reel is a winding device involving water pipes, air pipes, and cables, which includes a reel, a winding spring, and a self-locking pawl positioned between the left and right shells through a fixed shaft. The reel is equipped with winding discs on both sides, where the winding spring and the self-locking pawl are respectively located on both sides inside the reel. The inner end of the winding spring is fixedly connected to the fixed shaft, and the outer end is fixedly connected to the wall of the reel. The self-locking pawl is located on a fixed seat fixedly connected to the fixed shaft. There is a return spring between the self-locking pawl and the fixed seat. There are arc-shaped internal teeth on the reel corresponding to the tip of the self-locking pawl, and the tip of the self-locking pawl cooperates with the arc-shaped internal teeth. Suitable for coiling water pipes, air pipes, and cables, it has the advantages of simple structure, safety and reliability, long service life, and easy installation and use
The input end is connected to an external power cord (air source, water source) and does not have automatic expansion and contraction function< Output end wires (air and water pipes) can be connected to sockets and wiring boards (quick connectors). There is a self-locking device inside the scroll, which has an automatic wiring function. After pulling out a section of the cable, the self-locking device takes effect (the power cord stops moving). When the cable needs to be retracted, another section of the cable needs to be pulled out. When the cable passes over the self-locking device, gently hold the cable with your hand, and the cable will automatically retract. The automatic telescopic scroll can swing horizontally 180 degrees after being fixed< One end of the scroll is fixed on the wall or ceiling, and can be used to wrap cables, air pipes, water pipes, work lights, maintenance lights, and other cables inside. The input end of the cable reel is connected to an external power cord, which is usually a plug part (without automatic extension function); The power cord at the output end is equipped with a self-locking device, and the reel has an automatic wiring function. After pulling out a section of the cable, the self-locking device comes into effect (the power cord stops moving). If you want to retract the cable, you need to pull out another section of the cable. When the cable passes through the self-locking device and is released, the cable will automatically retract
The principle of the tracheal spool is similar to that of the tracheal spool. The working principle is as follows: the input end is connected to a section of tracheal tube, and the output end is equipped with a self-locking device. The spool has an automatic wiring function. After pulling out a section of tracheal tube, the self-locking device takes effect (the tracheal tube stops moving). If you want to retract the tracheal tube, you need to pull out another section outward. After the tracheal tube passes through the self-locking device, release the tracheal tube and retract it
