Description
Technical Field
The utility model relates to a sealing device, more specifically relates to a ball round pin dust cover.
Background
An automotive steering ball pin is one of important components for realizing a transmission function in a vehicle, and is used for realizing the work of a plurality of components in the automobile through the rotation of a ball pin arranged in a ball pin casting body. In order to ensure that the ball pin can keep good working performance, a dust cover is usually arranged outside the ball pin to avoid the influence of dust entering the ball pin on the performance of the ball pin; however, in the ball pin dust cover in the prior art, the dust cover rotates with the ball pin for a long time, and a gap often appears at the joint between the dust cover and the ball pin, so that the sealing performance of the dust cover is seriously reduced, the dust prevention effect is reduced, and the performance and the service life of the ball pin are affected.
SUMMERY OF THE UTILITY MODEL
It is so to have an inspection, the utility model provides a ball round pin dust cover that dustproof effect is good, stable in structure, sealed effectual.
In order to solve the problem, the utility model adopts the following technical scheme:
the utility model provides a ball round pin dust cover, its outside of settling in the ball round pin casting body which characterized in that: including setting up in the dust cover body of ball round pin casting body outside, being located the shaft hole of dust cover body upper end and being located the seal lip of dust cover body lower extreme, the dust cover body is equipped with the arch that is used for strengthening dustproof effect, the seal lip is equipped with the skeleton.
Preferably, the framework is made of metal.
Preferably, the dust-proof cover body is made of rubber.
Preferably, the framework has a V-shaped cross-section.
Preferably, the sealing lip is of annular configuration.
Preferably, the skeleton is located inside the sealing lip.
Preferably, the protrusion is of annular configuration.
The utility model discloses an increase a protruding structure on traditional dust cover body, be favorable to strengthening its dustproof effect, the skeleton setting can prevent that the skeleton from being corroded and coming off in the inside of seal lip, influences dustproof effect, guarantees ball round pin normal work, improves the life-span of ball round pin, and the skeleton is the metal material, and the dust cover body is the rubber material, and the transversal V-arrangement of personally submitting of skeleton, and the seal lip is the loop configuration, and the arch is the loop configuration, is favorable to guaranteeing the steadiness of dust cover.
