Embodiment Construction
[0020] like figure 1 ——As shown in 6, a pull cord release device includes a plastic base 1, an internal threaded pipe 2, a reticulated nut 3, a spring 4, a steel ball with a handle 5, a pin 6, a sealing ring 7,
[0021] The plastic base 1 wraps the internally threaded pipe 2, the middle part of the pipe wall of the internally threaded pipe 2 has a hole 10 and penetrates the plastic base 1, and the two ends of the internally threaded pipe 2 have internal threads 8, 9,
[0022] The steel ball 5 with a handle is in the shape of a cylindrical connection steel ball, the spring 4 is set on the outer circle of the cylinder with the steel ball 5, and the two ends of the inner threaded pipe 2 are respectively provided with reticulated nuts 3 to screw the steel ball 5 and the spring 4 in;
[0023] One end of the latch 6 has a latch through hole 12, and the outer circumference of the other end of the latch 6 has a sealing groove and a spherical groove 13,
[0024] The plug pin 6 is inse...

The invention relates to a pull rope separating device. A plastic base wraps an internal ribbed tube, the middle part of the wall of the ribbed tube is provided with a hole and penetrates through the plastic base, the two ends of the ribbed tube are provided with internal thread, a steel ball with handle is in the shape of cylinder connected with steel ball, a spring is sheathed on the excircle of the cylinder of the steel ball with handle, the two ends of the ribbed tube are respectively provided with a ribbed nut to cause the steel ball with handle and the spring to be twisted in; and one end of a bolt is provided with a bolt through hole, and the periphery of the other end of the bolt is provided with a seal groove and a spherical groove. Pressure of the spring forces the steel ball of the steel ball with handle at the two ends to be tightly contacted with the spherical groove of the bolt, and a seal ring forms friction force for the bolt to separate from the plastic base. The tension required at separation is adjusted by utilizing the spring. When reaching the set tension, the bolt is separated from the plastic base. The invention has the beneficial effect that the pull rope separator can utilize impulsive force of motorcycle to initiate starting device, so as to separate people from the motorcycle when a driver meets an accident. The plastic base is not easily separated from the bolt, thus avoiding false operation. The tension can be adjusted by adjusting the spring.
Description
technical field [0001] The invention relates to a pull cord release device, which belongs to the technical field of machinery. Background technique [0002] At present, the connection and detachment devices of ropes generally rely on the elastic force of the connectors, and it is very difficult to control the intensity of the detachment force. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art structure, the present invention provides a pull cord release device. [0004] The technical solution adopted by the present invention to solve the technical problem is: a pull cord disconnector, including a plastic base, an internal threaded pipe, a reticulated nut, a spring, a steel ball with a handle, a latch, a sealing ring, [0005] The plastic base wraps the internally threaded pipe. There is a hole in the middle of the pipe wall of the internally threaded pipe and runs through the plastic base. Both ends of the internall...
