Summary of the invention
The purpose of this utility model is to provide a kind of two-stage vibration damping fuel pipe pipe clamp assembly, to reduce the vibration that pipe clamp passes to vehicle body.
Two-stage vibration damping fuel pipe pipe clamp assembly described in the utility model, comprise pipe clamp seat and pipe clamp lid, described pipe clamp lid is fastened on the pipe clamp seat, offer two bolt via holes at pipe clamp seat and pipe clamp Gai Zhongjun, described pipe clamp seat and pipe clamp lid is connected with double-screw bolt on being fixed on body platform by described bolt via hole, and fix with nut, be with spring at described double-screw bolt, one end of this spring and body platform are conflicted, the other end is pressed on the interior positive stop lug boss of bolt via hole, and described pipe clamp seat does not contact with body platform under spring action; Cover the rubber dampers that respectively are provided with two band half slots respectively at pipe clamp seat and pipe clamp, two rubber dampers that described pipe clamp covers respectively with two of corresponding formations of two rubber dampers on the pipe clamp seat for the fixing fixed hole of fuel pipe.
Further, an end of described pipe clamp lid and pipe clamp seat is connected as a single entity by flexible connection piece, and the pipe clamp lid can be around this flexible connection piece rotation.
Further, offer limit sliding chutes at the outer wall of described rubber damper, cover at pipe clamp seat and pipe clamp and be equipped with the spacing barb that cooperates with this limit sliding chutes, limit sliding chutes with can prevent the loosening of rubber damper cooperating of spacing barb.
Further, in the half slot of described rubber damper, be provided with the clamping convex tendon, with the fuel pipe in the hole that is fixedly clamped, prevent that fuel pipe is loosening.
Further, be provided with first positioning block at the middle part of described pipe clamp seat, cover at pipe clamp and be provided with the first corresponding positioning groove, this first positioning block is inserted in this first positioning groove.
Further, also be provided with second positioning block at an end of described pipe clamp seat, cover at pipe clamp and be provided with the second corresponding positioning groove, this second positioning block is inserted in second positioning groove.
Further, be provided with the spline platform at described double-screw bolt, described nut screwing clamping is at this spline platform place, to avoid undue holddown spring.
The beneficial effects of the utility model are: the secondary vibration damping of the one-level vibration damping by the rubber damper that contacts with fuel pipe and the spring that contacts with body platform, realize flexibly connecting of fuel pipe and pipe clamp assembly, pipe clamp assembly and vehicle body, therefore greatly reduced the vibration that fuel pipe passes to vehicle body.And the assembling of this pipe clamp assembly is simple, and accurate positioning can fixedly secure two fuel pipes simultaneously.
