The utility model discloses set up the oil filler point direct alignment bulb position on the dust cover body, make oil pour into the dust cover inner chamber into easily to lubricate the bulb better, improve life, this structural strength is high, and dust seal is effectual, and can guarantee better reliably with being connected of bulb round pin.
Description
Technical Field
The utility model relates to a bulb dust cover that is used for bulb to connect position dustproof and waterproof in trades such as mechanical engineering, car.
Background
The bulb is connected and is used widely in trades such as mechanical engineering, car, for the bulb round pin that uses in the car control arm, for the nimble rotation of guaranteeing bulb round pin during operation, the bulb round pin generally all can set up the dust cover outward and carry out protection such as dustproof and waterproof, sets up the oil filler point at the afterbody of bulb round pin component simultaneously, and the shortcoming is: the oiling direction is not correct, the oiling is difficult, the ball head is difficult to be lubricated well, the lubricating effect is poor, and the service life is short.
Disclosure of Invention
The technical problem to be solved by the utility model is to provide a set up oil filler point direct aim at bulb position on the shield body, make oil pour into the dust cover inner chamber into easily to lubricate the bulb better, improve life's bulb dust cover.
The utility model discloses an adopt following technical scheme to realize:
bulb dust cover, including the dust cover body of rubber material, the dust cover body has upper and lower open end, its characterized in that: the side wall of the lower opening end of the dustproof cover body is provided with an oil filling hole, an oil filling channel of the oil filling hole is provided with a metal hole lining, a first skeleton ring is arranged in the lower opening end of the dustproof cover body, and the first skeleton ring and the metal hole lining are of an integrated stamping part structure.
The inner ring of the first skeleton ring is provided with spline teeth, tooth tops of the spline teeth are arranged around the inner wall of the lower opening of the dustproof cover body, and the tooth tops of the spline teeth do not expose the inner wall of the lower opening of the dustproof cover body.
And a second skeleton ring is arranged in the upper opening end of the dustproof cover body.
The inner wall of the upper opening of the dustproof cover body is provided with an annular sawtooth groove.
The upper end face of the dustproof cover body is provided with an annular end face groove.
After the technical scheme is adopted, the utility model has the advantages of it is following: 1. the dustproof cover body is provided with the oil filling hole, so that the oil filling hole can be directly aligned to the ball head part, oil is easily filled into the inner cavity of the dustproof cover, the ball head is better lubricated, the service life of the dustproof cover body is prolonged, the rubber dustproof cover body is reliably provided with the oil filling nozzle, and an oil filling channel of the oil filling hole is provided with a metal hole lining so as to be beneficial to installation of the oil filling nozzle; 2. the first and second framework rings are arranged in the upper and lower opening ends of the dustproof cover body, so that the structural strength of the dustproof cover is high, meanwhile, the inner ring of the first framework ring is provided with the spline teeth, the tooth tops of the spline teeth are arranged around the inner wall of the lower opening of the dustproof cover body, the point contact between the lower opening of the dustproof cover body and the excircle of the ball head seat body is realized, and the reliable connection between the dustproof cover and the ball head pin is better ensured; 3. the inner wall of the upper opening of the dustproof cover body is provided with the annular sawtooth groove, so that the sealing of the pin rod section of the ball pin can be increased, and the dustproof sealing effect is improved; 4. the up end of the dust cover body is provided with an annular end surface groove, the elastic deformation generated by compressing the up end of the dust cover body after installation increases the dust sealing effect of the up end direction of the dust cover, and the service life is prolonged.
