Abstract
The utility model discloses a framework type dust seal which comprises a reversed-L-shaped framework, a rubber body and a dustproof lip. A cross arm of the reversed-L-shaped framework extends outwards. The dustproof lip is composed of more than three dustproof lip lines. The framework type dust seal has the advantages of improving dustproof ability, being simple in assembly, and not improving the cost of a shock absorber.
Description
Technical field
The utility model belongs to the dust prevention of vibration absorber technical field, relates to the skeleton dust seal of a kind of three lips.
Background technique
The at present design of dust prevention of vibration absorber envelope has two kinds of designs basically, and a kind of is full glue dust seal, another kind of skeleton dust seal.Two kinds of designs respectively have pluses and minuses, and full glue dust seal cost is lower, and rigidity is slightly poor; Skeleton dust seal good rigidity, cost are slightly high, but its lip structure dust sealing is not enough.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and a kind of skeleton dust seal that dirt exclusion capabilities, assembling simply and not improve the vibration damper cost that can be applicable to improve is provided.
The purpose of this utility model is achieved in that a kind of skeleton dust seal, is comprised of skeleton, rubber body and dust excluder lips, is characterized in that the transverse arm of inverted L-shaped skeleton stretches out, and dust excluder lips is made of the above dust excluder lips in three roads.
The utility model is distinguishing feature and good effect compared with the prior art: the utility model is that the transverse arm of inverted L-shaped skeleton stretches out, dust excluder lips is made of the above dust excluder lips in three roads, dust seal has the support of metal frame, the good rigidity of lip, skeletal structure is reasonable, increase the service life, dust excluder lips is comprised of the above dust excluder lips in three roads, the dustproof lip of multiple tracks can seal up the fine dusts that enters by the dustproof lip in front effectively, thereby further improve the dirt exclusion capabilities of dust seal, can be applicable to improve dirt exclusion capabilities thereby make the utlity model has, assembling simply and not improves the characteristics of vibration damper cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Embodiment, a kind of skeleton dust seal, with reference to Fig. 1, the inside that skeleton 1 is wrapped in rubber body 2, skeleton 1 stretches out for the transverse arm of inverted L-shaped and inverted L-shaped skeleton 1, and the inboard of rubber body 2 extends to form dust excluder lips 3, and dust excluder lips 3 is made of the above dust excluder lips in three roads, present embodiment adopts three road dust excluder lips, and this consists of a kind of structure of the present utility model.
