Abstract
The utility model discloses a kind of damping dust plug, comprise cylindrical body, cylindrical body comprises position limit socket, breeze way and linkage section, and position limit socket is fixed by interference fit and breeze way one end, and linkage section and breeze way are fixed away from position limit socket one end; The periphery of position limit socket is provided with the bump of multiple outwardly convex, and above-mentioned bump is against the inwall of breeze way, and position limit socket is provided with multiple claw turned over to evagination away from linkage section one end, and above-mentioned claw and breeze way fasten away from the sidewall hook of linkage section side; Breeze way has ripple struction, from near position limit socket one end to away from position limit socket one end, above-mentioned ripple struction medium wave ripple length reduces gradually and wave pitch reduces gradually, breeze way is provided with some vents, from near position limit socket one end to away from position limit socket one end, the density of above-mentioned vent reduces gradually.Bellows disclosed in the utility model, its intensity is high, and anti-seismic performance is good, long service life.
Description
Technical field
The utility model relates to technical field of engines, particularly relates to a kind of damping dust plug.
Background technique
After the automobile running long period, the performance of vibration damper there will be decline, reason mainly in the process of moving road surface silt be splashed into the working position of vibration damper, have impact on the vibration damper life-span.This just needs at vibration damper arranged outside dust-proof cover.Damper dust-proof cover used in the market adopts cushion pad and bellows to form mostly, its deficiency is: because the elastic deformability of common bellows is poor, rock in the violent large intensity of vibration damper, when being similar under destructive work (as racing car racing track), easy distortion, causes fracture failure.
Model utility content
In order to solve the technical problem existed in background technique, the utility model proposes a kind of damping dust plug, its intensity is high, and anti-seismic performance is good, long service life.
A kind of damping dust plug that the utility model proposes, comprise cylindrical body, cylindrical body comprises position limit socket, breeze way and linkage section, and position limit socket is fixed by interference fit and breeze way one end, and linkage section and breeze way are fixed away from position limit socket one end; The periphery of position limit socket is provided with the bump of multiple outwardly convex, and above-mentioned bump is against the inwall of breeze way, and position limit socket is provided with multiple claw turned over to evagination away from linkage section one end, and above-mentioned claw and breeze way fasten away from the sidewall hook of linkage section side; Breeze way has ripple struction, from near position limit socket one end to away from position limit socket one end, above-mentioned ripple struction medium wave ripple length reduces gradually and wave pitch reduces gradually, breeze way is provided with some vents, from near position limit socket one end to away from position limit socket one end, the density of above-mentioned vent reduces gradually.
Preferably, on position limit socket, bump quantity is 4-6, and each bump is around the distribution of position limit socket circumference.
Preferably, the quantity 3-5 of position limit socket upper clipping claw is individual, and each dog rings is around the distribution of position limit socket circumference.
Damping dust plug in the utility model, in one end of breeze way, position limit socket is set, on the one hand, the bump of position limit socket periphery can support breeze way, improve the support strength to breeze way, reduce breeze way and occur circumference vibrations, on the other hand, claw on position limit socket can carry out spacing to breeze way, reduces breeze way and occurs axial float; Ripple struction on breeze way is designed to, from near position limit socket one end to away from position limit socket one end, ripple wavelength reduces gradually and wave pitch reduces gradually, thus make the breeze way of zones of different have different stretchability, thus adapt to the flexible requirement of each breeze way on its position, meanwhile, vent is set, contribute to preventing breeze way from telescopic process, producing negative pressure distortion, be conducive to the working life extending dust-proof cover; Therefore, it is high that above-mentioned dust-proof cover has intensity, and anti-seismic performance is good, the advantage of long service life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of damping dust plug that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the schematic diagram of a kind of damping dust plug that the utility model proposes.
With reference to Fig. 1, in one embodiment, a kind of damping dust plug that the utility model proposes, comprise cylindrical body, cylindrical body comprises position limit socket 3, breeze way 2 and linkage section 1, position limit socket 3 is fixed by interference fit and breeze way 2 one end, and linkage section 1 and breeze way 2 are fixed away from position limit socket 3 one end; The periphery of position limit socket 3 be provided with the bump of 6 outwardly convexs and each bump around the distribution of position limit socket 3 circumference, above-mentioned bump is against the inwall of breeze way 2, position limit socket 3 linkage section 1 one end is provided with 4 claws 4 turned over to evagination and each claw 4 around the distribution of position limit socket 3 circumference, above-mentioned claw 4 fastens with the sidewall hook of breeze way 2 away from linkage section 1 side; Breeze way 2 has ripple struction, from near position limit socket 3 one end to away from position limit socket 3 one end, above-mentioned ripple struction medium wave ripple length reduces gradually and wave pitch reduces gradually, breeze way 2 is provided with some vents 5, from near position limit socket 3 one end to away from position limit socket 3 one end, the density of above-mentioned vent 5 reduces gradually.
In the above-described embodiments, in one end of breeze way 2, position limit socket 3 is set, on the one hand, the bump of position limit socket 3 periphery can support breeze way 2, improve the support strength to breeze way 2, reduce breeze way 2 and occur circumference vibrations, on the other hand, claw 4 on position limit socket 3 can carry out spacing to breeze way 2, reduces breeze way 2 and occurs axial float; Ripple struction on breeze way 2 is designed to, from near position limit socket 3 one end to away from position limit socket 3 one end, ripple wavelength reduces gradually and wave pitch reduces gradually, thus make the breeze way 2 of zones of different have different stretchability, thus adapt to the flexible requirement of each breeze way 2 on its position, meanwhile, vent 5 is set, contribute to preventing breeze way 2 from telescopic process, producing negative pressure distortion, be conducive to the working life extending dust-proof cover; Therefore, it is high that above-mentioned dust-proof cover has intensity, and anti-seismic performance is good, the advantage of long service life.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
