By adopting technique scheme, increased the Joint strenght of this kind of car puller hook therefore use multiple rod members to increase connecting portion simultaneously; Elastic telescopic rod member due to what use around connecting rod, when racing occurring in the time dragging or turning anxious extraordinary circumstances of stopping and so on, there is good buffering effect, greatly reduce in above-mentioned pulling force and the impact of impulsive force on towed vehicle and a kind of car puller hook of the utility model in particular cases, can well solve surface of vehicle distortion and short problem of car puller hook life-span.
The utility model is further set to: described elastic telescopic rod member and connecting rod are in the same plane, and described elastic telescopic rod member is symmetrically distributed in the both sides of described connecting rod.
By adopting technique scheme, adopt conplane being symmetrically distributed in to ensure when the utility model is attractive in appearance to avoid elastic bar to produce axial power to hinge-point, thereby make to the utlity model has service life more of a specified duration.
The utility model is further set to: described connecting rod and the tapered distribution of described elastic telescopic rod member, one end that opening is little is positioned at and described car puller hook body coupling end.
By adopting technique scheme, share by the elastic telescopic rod member that setting is with it angle distribution connecting rod around stressed, thereby increase the tensile strength of this kind of car puller hook.
The utility model is further set to: described connection base is provided with some the first hinged seats, described car puller hook body is provided with some the second hinged seats, described the first hinged seat and the second hinged seat are triangular in shape, and described the first hinged seat and the second hinged seat top are circular arc.
By adopting technique scheme, use hinged seat to reinforce interface point, thereby avoid connecting rod and elastic telescopic rod member and the contact that is connected base, car puller hook body and hinged seat to prevent that touching from causing damage or distortion simultaneously.
The utility model is further set to: described connection base is provided with some through holes for installing.
By adopting technique scheme, use detachable replacing easy for installation and repairing.
In sum, a kind of car puller hook of the utility model has buffer protection vehicle, the advantages such as stronger tensile strength and Joint strenght and longer service life.

Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of car puller hook of the utility model is described further.
As shown in Figure 1, a kind of car puller hook, comprise car puller hook body 3, connect base 1, connecting rod 4 and two are distributed in connecting rod 4 elastic telescopic rod member 2 around, increased the Joint strenght of this kind of car puller hook therefore use multiple rod members to increase connecting portion simultaneously, described car puller hook is annular arrangement, cirque structure is simple, the large larger transport truck of weight that is relatively applicable to of intensity, described elastic telescopic rod member 2 and connecting rod 4 are in the same plane, described elastic telescopic rod member 2 is symmetrically distributed in the both sides of described connecting rod 4, adopt conplane being symmetrically distributed in to ensure when the utility model is attractive in appearance to avoid elastic bar to produce axial power to hinge-point, thereby make to the utlity model has service life more of a specified duration.
The two ends of described connecting rod 4 and elastic telescopic rod member 2 are respectively with described car puller hook body 3 with to be connected base 1 hinged, described connecting rod 4 is identical with elastic telescopic rod member 2 rotation directions, and rotating shaft core line is perpendicular to described elastic telescopic rod member 2 and connecting rod 4 place planes, described connecting rod 4 and elastic telescopic rod member 2 place straight lines intersect at and described car puller hook body 3 pin jointed ends, elastic telescopic rod member 2 due to what use around connecting rod 4, the elastic telescopic rod member 2 that is with it angle distribution around connecting rod 4 by arranging is shared stressed, thereby increase the tensile strength of this kind of car puller hook, when racing occurring in the time dragging or turning anxious extraordinary circumstances of stopping and so on, there is good buffering effect, greatly reduce in above-mentioned pulling force and the impact of impulsive force on towed vehicle and a kind of car puller hook of the utility model in particular cases, can well solve surface of vehicle distortion and short problem of car puller hook life-span.
Described connection base 1 is provided with six and is evenly distributed on the through hole 11 of connection base 1 both sides for installing, and by adopting technique scheme, uses detachable replacing easy for installation and repairing.
As shown in Fig. 1 to 2, described connection base 1 is provided with three and is positioned at same level line and well-distributed the first hinged seat 12, described car puller hook body 3 is provided with three the second connected hinged seats 31, described the first hinged seat 12 and the second hinged seat 31 are triangular in shape, described the first hinged seat 12 and the second hinged seat 31 tops are circular arc, described the first hinged seat 12 and the second hinged seat 31 are crown center and are provided with the groove that runs through two prisms, the two ends of described pipe link and elastic telescopic rod member 2 are equipped with the lug with hinge hole, described lug end face is circular arc, described lug thickness matches with described groove, by adopting technique scheme, use hinged seat to reinforce interface point, avoid connecting rod 4 and elastic telescopic rod member 2 simultaneously and be connected base 1, thereby the contact of car puller hook body 3 and hinged seat prevents touching and causes damage or distortion.
As shown in Figure 2 to Figure 3, described elastic telescopic rod member 2 is spring 22 expansion links, described spring 22 expansion links comprise sleeve 21, sliding bar 23 and spring 22, described sliding bar 23 is slidably mounted in sleeve 21, one end that described sliding bar 23 is positioned at sleeve 21 is provided with bulge loop, described spring 22 is enclosed within on sliding bar 23 and one end is fixed on described bulge loop, and interior sliding bar 23 external parts of the other end and sleeve 21 are affixed.At present elastic telescopic rod member 2 kinds are roughly divided into that spring 22 is flexible, three classes are contracted in the gentle pressure stretch of hydraulically extensible, and the object of selecting spring 22 expansion links is mainly in order to reduce production costs.
A kind of car puller hook of the utility model also has another embodiment in scope with sovereign right, in above-described embodiment, absolutely prove effect when a kind of car puller hook level of the utility model is arranged on vehicle, under the prerequisite of same structure, a kind of the utility model car puller hook is vertically arranged on to the vehicle being formed by Uneven road can also solve on some unfairness hill paths trailer on vehicle time and shakes mutually and produce the problem of larger vibration, can fully alleviate the mutual interference of vehicle part phase.
