Abstract

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

A kind of pull rope separating device

Technical field

The present invention relates to a kind of pull rope separating device, belong to field of mechanical technique.

Background technology

The present dockingundocking device of rope generally relies on the elastic force of attaching parts, and controlling it, to break away from intensity of force very difficult.

Summary of the invention

In order to overcome the deficiency of above-mentioned prior art structure, the invention provides a kind of pull rope separating device.

The technical scheme that technical solution problem of the present invention is adopted is: a kind of pull rope separating device, comprise plastic base, and rifled pipe, the reticulate pattern nut, spring is with steel ball, latch, seal ring,

Plastic base parcel rifled pipe, the tube wall middle part of rifled pipe is porose and connect out plastic base, and there is negative thread at the rifled pipe two ends,

Band is steel ball that cylinder connects the steel ball shape, spring housing band the cylinder cylindrical of steel ball on, the two ends of rifled pipe have the reticulate pattern nut to be with respectively steel ball and spring are screwed into;

One end of latch has the latch through hole, and the excircle of the other end of latch has seal groove and spherical groove,

Latch inserts in the hole of rifled pipe, and the spherical groove of latch contacts the steel ball of steel ball coupling with band, and the seal groove of latch is installed the seal ring contact in the hole of rifled pipe.

The pressure of spring forces the steel ball of (the two ends band is steel ball) and the spherical groove closed contact of latch, and seal ring forms the friction force that latch breaks away from plastic base.

Utilize spring to regulate needed pulling force when breaking away from.Latch breaks away from plastic base when reaching the pulling force that sets.

Beneficial effect of the present invention is specific as follows:

Pull rope separating device is when solving chaufeur and running into accident by motorcycle, can utilize the impulse force of motor bike to start the effect that starter gear relief people car separates.

Plastic base 1 can not break away from easily with latch 6, avoids misoperation.Regulating spring scalable pulling force.

The specific embodiment

As Fig. 1--shown in 6, a kind of pull rope separating device comprises plastic base 1, rifled pipe 2, reticulate pattern nut 3, spring 4 is with steel ball 5, latch 6, seal ring 7,

Plastic base 1 parcel rifled pipe 2, the tube wall middle part porose 10 of rifled pipe 2 also connects out plastic base 1, and there is

negative thread

8,9 at rifled pipe 2 two ends,

Band is cylinder connection steel ball shape to steel ball 5, and spring 4 is enclosed within to be with on the cylinder cylindrical of steel ball 5, and the two ends of rifled pipe 2 have reticulate pattern nut 3 to be with respectively steel ball 5 and spring 4 are screwed into;

One end of latch 6 has latch through hole 12, and the excircle of the other end of latch 6 has seal groove and spherical groove 13,

Latch 6 inserts in the hole of rifled pipe 2, and the spherical groove 13 of latch 6 contacts the steel ball of steel ball 5 coupling with band, and the seal groove of latch 6 is installed seal ring 7 contacts in the hole 10 of rifled pipe 2.

The pressure of spring 4 forces the steel ball of steel ball 5 and the spherical groove closed contact of latch 6, and seal ring 7 forms the friction force that latch 6 breaks away from plastic base 1.

Plastic base 1 porose 11.Hole 11 connects draw ring, and the other end of draw ring connects starter gear.

Latch through hole 12 connecting ropes 15 of latch 6, the other end coupling hook ring 18 of rope 15, rope 15 are with

pressure head cover

16,17.
