For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
The connector rod guider that a kind of push-pull cable is elastic, including the connector rod being sequentially connected with, guide pipe and injection casing cover, guide pipe is internal cavity structures, and one end of guide pipe arranges tip side, if the inwall of described tip side is evenly arranged with dry elasticity boss；The other end of guide pipe is provided with bulb end；One end of described injection casing cover is provided with connection end, and the inwall of described connection end is provided with the spherical endoporus adapted with described bulb end；Connector rod is socketed in guide pipe through tip side；One end of guide pipe is connected with injection casing cover, and the other end of guide pipe is connected to connector rod thus realizes guide function；Guide pipe and connector rod are provided with elastic boss on tip side inner wall of end, when connector rod does pivot angle and axially-movable in guide pipe, receive certain elastic pre-stress that elastic boss provides, it is to avoid the sound that connector rod produces because of matched in clearance with guide pipe.
Further, described connector rod one end arranges flat hollow out end, and flat hollow out end is connected with change speed gear box, and the connector rod other end axially moves in guide pipe.
Preferably, the cross section of described elastic boss clamping end is circular arc.
Preferably, described connector rod is elongated rod shape.
Preferably, described guide pipe is a rotary body, and connector rod can axially move in the endoporus of guide pipe.
Preferably, the quantity of the elastic boss on described tip side inwall is three, is evenly distributed, and utilizes the stability of triangle, stable elastic pre-stress, the size of this pretightning force is formed by elasticity boss simultaneously internal diameter and land length can be provided to be affected to connector rod.
Further, in described connection end, it is provided with spherical endoporus, is the basis of guide pipe installation, and the swing space of certain angle is provided to guide pipe.
The beneficial effects of the utility model: this utility model is by increasing, at guide pipe inwall, the independent boss that three bands are elastic, 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 doing pivot angle and axially-movable in so connector rod is assemblied in guide pipe, will be by the boss pretightning force to it, avoid the sound that connector rod produces because of matched in clearance with guide pipe, effectively reduce drag-line noise, provide good noiselessness effect to automobile.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained, broadly fall into the scope of this utility model protection.
As shown in Figure 1 to Figure 3, according to the connector rod guider that a kind of push-pull cable described in this utility model embodiment is elastic, including the connector rod 1 being sequentially connected with, guide pipe 2 and injection casing cover 3, guide pipe 2 is internal cavity structures, one end of guide pipe 2 arranges tip side 21, if the inwall of described tip side 21 is evenly arranged with dry elasticity boss 22；The other end of guide pipe 2 is provided with bulb end 23；One end of described injection casing cover 3 is provided with connection end 31, and the inwall of described connection end 31 is provided with the spherical endoporus 32 adapted with described bulb end 23；Connector rod 1 is socketed in guide pipe 2 through tip side 21；One end of guide pipe 2 is connected with injection casing cover, and the other end of guide pipe 2 is connected to connector rod 1 thus realizes guide function；Guide pipe 2 and connector rod 1 are provided with elastic boss 22 on tip side 21 inner wall of end, when connector rod 1 does pivot angle and axially-movable in guide pipe 2, receive certain elastic pre-stress that elastic boss 22 provides, it is to avoid the sound that connector rod 1 produces because of matched in clearance with guide pipe 2.
Described connector rod 1 one end arranges flat hollow out end, and flat hollow out end is connected with change speed gear box, and connector rod 1 other end axially moves in guide pipe 2.
