Embodiment Construction
[0020] Such as 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 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 in the steel ball 5 and the spring 4;
[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 in...

The utility model relates to a pull-rope disconnector. A plastic base wraps an internally threaded pipe, the middle of the pipe wall of the internal threaded pipe is provided with a hole and passes through the plastic base; It is sleeved on the cylindrical outer circle with the handle steel ball, and there are mesh nuts at both ends of the inner threaded pipe to screw the handle steel ball and the spring into it; one end of the bolt has a through hole for the bolt, and the outer circumference of the other end of the bolt has a sealing groove. and spherical grooves. The pressure of the spring forces the steel balls with the steel balls at both ends to be in close contact with the spherical grooves of the plug, and the sealing ring forms the frictional force of the plug from the plastic base. The tension required for disengagement is adjusted with a spring. The latch is released from the plastic base when the set tension is reached. Beneficial effects: The pulling rope release device is used to solve the function of separating the driver from the vehicle by using the momentum of the motorcycle to activate the starting device when the driver encounters an accident while riding a motorcycle. The plastic base and the latch will not be easily disengaged to avoid misoperation. Adjustable spring to adjust tension.
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 release device, 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 interna...
