Abstract
The utility model discloses a dustproof bumper block which comprises a bumper block body and a hard dustproof cover arranged at the lower end of the bumper block body. A through hole is formed inside the bumper block body, the lower end of the hard dustproof cover is provided with a soft dustproof cover, and the hard dustproof cover and the soft dustproof cover are integrated. The dustproof bumper is simple in structure, strong in dustproof capability, good in using effect and capable of isolating the outside dust and sandstones, and a piston rod and an oil seal of an absorber are effectively protected.
Description
Technical field
The utility model belongs to automobile component, is specifically related to a kind of automotive suspension dustproof bumper block.
Background technique
Current most of automobile adopts suspension frame structure; in the situation that road conditions are poor; in existing suspension frame structure, be provided with buffer stopper and limit suspension travel; to absorb, from wheel, pass to the impulsive load vehicle body; conventionally buffer stopper is arranged on the piston rod of vibration damper; vehicle plays buffer function when motion; yet the mounting point of vibration damper has determined that it is in rugged environment always; the dust coming from the outside and sandstone are constantly attacked piston rod and the oil sealing of vibration damper; piston rod and oil sealing are worn, cause damper leakage and inefficacy.
Chinese patent CN201020223656.7 discloses a kind of dustproof bumper block, it is characterized in that: it comprises the dustproof portion of tubular and is arranged on the buffer part of dustproof portion end, the inner side of buffer part is along the through hole that runs through buffer part that is axially arranged with of dustproof portion, the cavity that the through hole of buffer part inner side and dustproof portion surround communicates with each other, and described dustproof portion and buffer part are connected as a single entity.Although this model utility plays certain dustproof buffer action, do not avoid piston rod and the oil sealing of dust and sandstone invasion and attack vibration damper completely.
Model utility content
The utility model is for the problems referred to above, and a kind of simple in structure, dirt exclusion capabilities is strong, using effect is good dustproof bumper block is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of dustproof bumper block, comprise buffer stopper and the hard dust-proof cover that is arranged on buffer stopper lower end, described buffer stopper inside is provided with through hole, it is characterized in that: described hard dust-proof cover lower end is provided with soft dust-proof cover, and described hard dust-proof cover and soft dust-proof cover are integrated.
Further, described soft dust-proof cover is tapered, and described soft dust-proof cover lower end is provided with protective port.
Further, described buffer stopper cylindrical upper end is provided with the outer groove of ring-type, and described buffer stopper cylindrical middle part is provided with rectangle annular groove.
Further, described annular groove inner sleeve has plastics hoop.
Further, described through-hole wall is provided with ring-type inner groovy.
Further, described buffer stopper one end is provided with connecting groove.
Further, described hard dust-proof cover is connected with buffer stopper by connecting groove.
The utility model has the advantages that: the utility model is simple in structure, dirt exclusion capabilities is strong, using effect is good.
Except object described above, feature and advantage, the utility model also has other object, feature and advantage.Below with reference to figure, the utility model is described in further detail.
Accompanying drawing explanation
The accompanying drawing that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of dustproof bumper block of the present utility model.
Reference character:
1 is that buffer stopper, 2 is that annular groove, 3 is that plastics hoop, 4 is that through hole, 5 is that connecting groove, 6 is that hard dust-proof cover, 7 is that soft dust-proof cover, 8 is that protective port, 9 is that outer groove, 10 is inner groovy.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
With reference to figure 1, a kind of dustproof bumper block as shown in Figure 1, comprise buffer stopper 1 and the hard dust-proof cover 6 that is arranged on buffer stopper 1 lower end, described buffer stopper 1 inside is provided with through hole 4, and described hard dust-proof cover 6 lower ends are provided with soft dust-proof cover 7, and described hard dust-proof cover 6 is integrated with soft dust-proof cover 7, integral structure design is convenient to install, can reduce the Short Item that installation and maintenance cause, also can reduce installation time, save material; Described soft dust-proof cover 7 is tapered, and described soft dust-proof cover 7 lower ends are provided with protective port 8, and the conical design of soft dust-proof cover 7 is convenient to the piston rod of protection motion, prevents that dust from entering in soft dust-proof cover 7; Described buffer stopper 1 cylindrical upper end is provided with the outer groove 9 of ring-type, described through hole 4 inwalls are provided with ring-type inner groovy 10, described buffer stopper 1 cylindrical middle part is provided with rectangle annular groove 2, described annular groove 2 inner sleeves have plastics hoop 3, and such structural design can guarantee that this dustproof bumper block has good vibration damping, buffering and energy absorption performance; Described plastics hoop 3 can improve the rigidity of buffer stopper 1, also has the effect of explosion while preventing the compression of this dustproof bumper block; Described buffer stopper 1 one end is provided with connecting groove 5; Described hard dust-proof cover 6 is connected with buffer stopper 1 by connecting groove 5, and when the setting of connecting groove 5 is convenient for changing and keeps in repair while being convenient to each parts damages, convenient inspection dismantled; Described protective port 8 closely cooperates with oil storage cylinder of shock absorber, can, by extraneous dust and sandstone isolation, effectively protect piston rod and the oil sealing of vibration damper.
The utility model is simple in structure, dirt exclusion capabilities is strong, using effect is good, can, by extraneous dust and sandstone isolation, effectively protect piston rod and the oil sealing of vibration damper.
The foregoing is only preferred embodiment of the present utility model, the utility model includes but not limited to this example, and the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
