Technical field

This utility model relates to vehicle fuel feed system, is specifically related to the pipe clamp of a kind of band vibration-proof structure.

Background technology

Along with the requirement of automotive quality is improved by consumer day by day, automobile noise and vibration are increasingly subject to the concern of society, It is relatively big that vehicle fuel pipe moves towards span, for arranging specification, it is to avoid interfere, it usually needs with multiple pipe clamps, oil pipe is fixed on vehicle body Diverse location.The existing pipe clamp 1 that at present fixing oil pipe 13 is used as it is shown in figure 1, it is fixed on body platform 14, existing pipe Folder central aperture, coordinates hole with the welding screw 12 on body platform, then coordinates with welding screw with existing nut 11 and tighten, Existing pipe clamp is compressed and fits in body platform plane.This mounting means, is Hard link between pipe clamp and vehicle body, transports at vehicle During row, in pipe, vibration and the pipe of the generation of flowing of liquid are the most directly passed through to manage by the vibration that external interference causes Folder is delivered to vehicle body, the most directly causes car load vibration noise higher.CN202868084U discloses " a kind of vibration damping pipe Folder ", including: support, described support one end is fastened on pipeline, and the other end is connected on vehicle body, helps for fixed car hydraulic pressure Power steering pump pipeline；Rubber sleeve, is lining in described support in described rubber sleeve；Rubber blanket, described rubber blanket is arranged on described Frame is connected to the one end on vehicle body.The vibration of automobile hydraulic electric power steering pump conduit can be played well by described vibration damping pipe clamp Twin-stage attenuation.Certainly, this is a kind of useful exploration of art.

Summary of the invention

The purpose of this utility model is to provide the pipe clamp of a kind of band vibration-proof structure, and it can not only avoid oil pipe vibration to be passed It is delivered to vehicle body, and pipe clamp body axial motion can also be limited, reduce the noise of car load, improve the comfortableness of car load.

The pipe clamp of a kind of band vibration-proof structure described in the utility model, including pipe clamp body, sets at the middle part of pipe clamp body There are vertical installing hole, both sides to be provided with the clamp structure of clamping oil pipe, it is characterized in that:

The installing hole of the one shock-reducing sleeve described pipe clamp body of press-in is interior and two ends flush with the two ends of installing hole, described shock-reducing sleeve Inwall be mating holes；

One metal liner is pressed into from the mating holes lower end of described shock-reducing sleeve, the bushing pipe seat of described metal liner and pipe clamp body Below be close to, the upper surface of described metal liner is slightly above the upper end of mating holes, and the inwall of described metal liner is bushing pipe hole；

One stud is vertically welded on body platform, the bushing pipe borehole jack of described metal liner in the outside of stud, described spiral shell The upper end of post is stretched out bushing pipe hole and is connected with a dish type cap nut screw connection.

Further, the diameter of the flange face of described dish type cap nut is more than the external diameter of described shock-reducing sleeve.

Further, described pipe clamp body uses integral molded plastic molding.

This utility model is to add shock-reducing sleeve (rubber sleeve) between pipe clamp body and body platform, derives from oil pipe Vibration needs just can be delivered to body platform by rubber blanket, makes pipe clamp body directly and the connection of body platform becomes pipe clamp originally Body, rubber blanket, the flexibly connecting of body platform, pipe clamp body is fixing with oil pipe and body platform uses nut to be connected, and makes pipe clamp Convenient and reliable assembly.This utility model has been reached to reduce oil pipe and has been delivered to the vibration of vehicle body, and pipe clamp effectiveness in vibration suppression by pipe clamp Adjustable, assemble light, difficult drop-off, accurate positioning.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further described.

The pipe clamp of a kind of band vibration-proof structure shown in Figure 2, uses integral molded plastic molding including pipe clamp body 21, at pipe The middle part of folder body is provided with vertical installing hole 211, both sides are provided with the clamp structure of clamping oil pipe 13, and its substantive distinguishing features is:

In one shock-reducing sleeve 22 is pressed into the installing hole 211 of described pipe clamp body 21 and two ends flush with the two ends of installing hole, institute The inwall stating shock-reducing sleeve is mating holes 221；

One metal liner 23 is pressed into from mating holes 221 lower end of described shock-reducing sleeve 22, the bushing pipe seat 231 of described metal liner It is close to below pipe clamp body 21, the upper end of the upper surface 232 slightly above mating holes 221 of described metal liner, described metal The inwall of bushing pipe is bushing pipe hole 233；

One stud 24 is vertically welded on body platform 14, and the bushing pipe hole 233 of described metal liner 23 is enclosed within stud 24 Outside, the upper end of described stud is stretched out bushing pipe hole and is connected with a dish type cap nut 25.The flange of described dish type cap nut 25 The diameter in face is more than the external diameter of described shock-reducing sleeve 22.

During assembling, see Fig. 2 and Fig. 3, first shock-reducing sleeve is pressed in the installing hole in pipe clamp body, make the two ends of shock-reducing sleeve Face flushes with the both ends of the surface of installing hole, is pressed in the mating holes of shock-reducing sleeve by metal liner the most again, makes the upper end of metal liner Face is more slightly higher than the end face of shock-reducing sleeve, and makes to be close to below bushing pipe seat and pipe clamp body, bushing pipe hole be vertically welded on vehicle body ground Stud on plate coordinates, and bushing pipe seat is fitted with body platform, finally, then is connected with stud by dish type cap nut, dish type cap The flange face of nut is pressed on the upper surface of metal liner, i.e. assembling puts in place.Owing to shock-reducing sleeve itself is more yielding, pipe clamp is originally Body, shock-reducing sleeve, metal liner assembling simplicity, difficult drop-off.

Owing to the upper surface of metal liner is more slightly higher than the upper surface of the upper end of shock-reducing sleeve, installing hole, dish type cap nut Flange face (i.e. dish type shade) is big compared with the upper surface of metal liner, also big than the upper surface of shock-reducing sleeve, therefore, and dish type cap nut Flange face both can guarantee that the upper surface pushing down metal liner, again the upper surface of malcompression shock-reducing sleeve and pipe clamp body, but can limit Shock-reducing sleeve processed and the axial motion of pipe clamp body.

Having had the flexible anti-vibration effect of shock-reducing sleeve between pipe clamp body and metal liner, effectiveness in vibration suppression can be by regulation metal Bushing pipe realizes relative to the hardness of shock-reducing sleeve and the relative altitude of pipe clamp body and regulation shock-reducing sleeve, the vibration nothing of pipe clamp body Method is directly delivered on body platform by metal liner, thus plays the effect of damping vibration.
