For realizing above-mentioned technical purpose, the technical scheme of the present invention is achieved in that
A kind of elastic connector rod liner of push-pull cable, comprises the connector rod, guide pipe and the injection moulding sleeve pipe lid that connect successively, and guide pipe is internal cavity structures, and one end of guide pipe arranges tip side, and the inwall of described tip side is evenly provided with some elasticity boss; The other end of guide pipe is provided with bulb end; One end of described injection moulding sleeve pipe lid is provided with coupling end, the spherical interior hole that the inwall of described coupling end is provided with described bulb end adapts; Connector rod is socketed in guide pipe through tip side; One end of guide pipe is connected with injection moulding sleeve pipe lid, and the other end of guide pipe is connected to connector rod thus realizes guide function; Guide pipe and connector rod are provided with elasticity boss on tip side inner wall of end, when connector rod does pendulum angle and axial motion in guide pipe, receive certain elasticity preliminary tension that elasticity boss provides, avoid connector rod and the sound that guide pipe produces because of running fit.
Further, described connector rod one end arranges flat hollow out end, and flat hollow out end is connected with wheel box, and the connector rod the other end axially moves in guide pipe.
Preferably, the cross section that described elasticity boss card is tightly held is circular arc.
Preferably, described connector rod is elongated rod shape.
Preferably, described guide pipe is a rotator, and connector rod can axially move in the interior hole of guide pipe.
Preferably, the quantity of the elasticity boss on described tip side inwall is three, is evenly distributed, and utilizes the stability of trilateral, stable elasticity preliminary tension can be provided, the size of this preliminary tension is formed by elasticity boss simultaneously internal diameter and the impact of land length to connector rod.
Further, it is provided with spherical interior hole in described coupling end, it is the basis that guide pipe is installed, and the swing space of certain angle is provided to guide pipe.
The useful effect of the present invention: the present invention is by increasing by three elastic independent boss of band at guide pipe inwall, the internal diameter that three boss are formed is less than the internal diameter in other regions of guide pipe, also the external diameter of connector rod it is slightly less than, when such connector rod is assemblied in guide pipe to do pendulum angle and axial motion, boss will be subject to its preliminary tension, avoid connector rod and the sound that guide pipe produces because of running fit, effectively reduce drag-line noise, provide to automobile good in noise result.
