Abstract

The utility model relates to a highly flexible compact type sleeve used as driving pushing and pulling rope assembly. The highly flexible compact type sleeve comprises an internal lining pipe 1, a circular shaped steel wire 2 that is entwisted around the circumference of the internal lining pipe, and a coating 3 that covers onto the external circumference of the circular shaped steel wire. The utility model is characterized in that the steel wire 2 is closely arranged on the external circumference at the external wall of the internal lining pipe 1. The steel wires keep a certain distance with each other. The external circumference of the coating 3 that covers onto the external circumference of the circular shaped steel wire 2 takes a circular shape, and is filled into all the gaps between the steel wire and steel wire 2, between the steel wire 2 and the internal lining pip 1. The three components jointly form a compact pipeline sleeve. The utility model improves the softness of the sleeve. After the sleeve is bent, the changes on the shape and dimension of the internal hole are very small without increasing the resistance of reciprocating movement in the sleeve to the pushing pulling rope. The utility model also is beneficial for improving the application lifetime and safety as well as reliability of the driving pushing, pulling rope assembly.

Description

High flexibility compact-type stopper push-pull cable assembly sleeve pipe

Technical field:

The utility model relates to a kind of high flexibility compact-type stopper push-pull cable assembly sleeve pipe.Adapt to automobile, engineering machinery remote stopper control system.

Background technology:

The sleeve pipe of traditional ordinary construction form as shown in Figure 2, steel wire is compact arranged in the bushing pipe peripheral distribution, the periphery coat only contacts with the part surface in the steel wire outside, between steel wire and steel wire, have space A between steel wire and internal lining pipe, its flexibility is poor, and what have relative slippage between internal lining pipe and steel wire may, cause crooked when excessive, the knee inner diameter diminishes, and round pass changes, and has influenced the crank motion of cable core in sleeve pipe.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, a kind of high flexibility compact-type stopper push-pull cable assembly sleeve pipe is provided, satisfy sleeve pipe and have under enough rigidity and the elastomeric condition, improve its flexibility, adapt to deploying to ensure effective monitoring and control of illegal activities of crooked stroke, do not influence the motion of cable core in sleeve pipe.

The purpose of this utility model is achieved in that a kind of high flexibility compact-type stopper push-pull cable assembly sleeve pipe, comprise internal lining pipe, twist with the fingers and be coated on the coating of round wire periphery around the round wire of internal lining pipe periphery, being characterized in that steel wire is close on the internal lining pipe outer wall circumference distributes, do not contact between steel wire and steel wire, and leave the gap, the coating periphery that is coated on the round wire periphery is for circular, and be full of between steel wire and steel wire, all spaces between steel wire and internal lining pipe, three kinds of members form closely knit tubular sleeve.

Sleeve pipe of the present utility model, the internal lining pipe periphery twist with the fingers around steel wire on circumference, has the well-distributed gap that suits, steel wire periphery coat not only is coated on the steel wire periphery, and be full of between steel wire and steel wire, all spaces between steel wire and internal lining pipe, around coating material and the every steel wire, all can closely glue (subsides) with internal lining pipe and close, formed the integral body of annular arrangement.Though whole sleeve pipe is made up of three parts, formed the tubular body of compact-type in fact, improved the flexibility of sleeve pipe.Behind the casing buckling, the variation of the shape and size of endoporus is little, can not increase push-pull cable reciprocating resistance in sleeve pipe, helps improving service life, safety and the reliability of stopper push-pull cable.The utility model has been expanded the range of use of sleeve pipe, has satisfied the operating needs of stopper push-pull cable assembly.

Description of drawings:

Fig. 1 is a cross-sectional structure scheme drawing of the present utility model.

Fig. 2 is the cross-sectional structure scheme drawing of existing sleeve pipe.

The specific embodiment:

As Fig. 1, the utility model relates to a kind of high flexibility compact-type stopper push-pull cable assembly sleeve pipe.It is the internal lining pipe 1 made by the plastic material of low-friction coefficient (polytetrafluoroethylene), twist with the fingers around high strength, the high tenacity round wire 2 of internal lining pipe periphery and be coated on the member of the tubular that the high-temperature resistance plastice coating 3 of round wire 2 peripheries forms.

Internal lining pipe 1 cross-sectional plane is an annular arrangement, and twisting with the fingers around the steel wire 2 of internal lining pipe 1 periphery is round section, and steel wire 2 is close to distribution equidistantly on the internal lining pipe 1 outer wall circumference.Steel wire 2 does not contact with 2 on steel wire, and leaves certain uniform gap, and coating 3 peripheries that are coated on round wire 2 peripheries are for circular, and is full of all spaces of 1 of steel wire 2 and 2 on steel wire, steel wire 2 and internal lining pipe.Three kinds of members form closely knit tubular sleeve.The sleeve pipe of this special structure form except that having the total characteristic of ordinary casing, and has fabulous flexibility.Adapt to automobile, limited space and the position of construction machinery and equipment transmission stopper, suitable bending is deployed to ensure effective monitoring and control of illegal activities, and does not influence the motion of cable core in sleeve pipe.
