Abstract
The invention discloses a ball head dust cover, which comprises a dust cover body made of rubber, wherein the dust cover body is provided with an upper opening end and a lower opening end, and is 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 dustproof cover body is provided with the oil injection hole which is directly aligned with the ball head, so that oil is easily injected into the inner cavity of the dustproof cover, the ball head is better lubricated, the service life is prolonged, the structure strength is high, the dustproof sealing effect is good, and the reliable connection with the ball head pin can be better ensured.
Description
Technical Field
The invention relates to a ball head dust cover for preventing dust and water at a ball head connecting part in the industries of mechanical engineering, automobiles and the like.
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
Aiming at the defects of the prior art, the invention aims to provide the ball head dust cover which is provided with the oil injection hole to directly align to the ball head part, so that oil is easily injected into the inner cavity of the dust cover, the ball head is better lubricated, and the service life is prolonged.
The invention is realized by adopting the following technical scheme:
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 invention has the following advantages: 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.
Drawings
The invention has the following drawings:
figure 1 is a view showing the configuration of the present invention,
figure 2 is a half-sectional view of figure 1,
fig. 3 is a schematic structural view of a first skeleton ring.
Detailed Description
As shown in the figure, the ball head dust cover comprises a dust cover body 1 made of rubber, wherein the dust cover body 1 is provided with an upper opening end and a lower opening end, an oil filling hole 4 is formed in the side wall of the lower opening end of the dust cover body 1, the oil filling hole 4 can be directly aligned with a ball head after the dust cover is installed, an oil filling channel of the oil filling hole 4 is provided with a metal hole lining 5, a first skeleton ring 2 is arranged in the lower opening end of the dust cover body 1, the first skeleton ring 2 and the metal hole lining 5 are of an integral stamping piece structure, the inner ring of the first skeleton ring 2 is provided with spline teeth 8, the tooth tops of the spline teeth 8 are arranged around the inner wall of the lower opening of the dustproof cover body 1, the tooth tops of the spline teeth 8 do not expose the inner wall of the lower opening of the dustproof cover body 1, the upper opening end of the dustproof cover body 1 is internally provided with a second skeleton ring 3, the inner wall of the upper opening of the dustproof cover body 1 is provided with an annular sawtooth groove 6, and the upper end face of the dustproof cover body 1 is provided with an annular end face groove 7.
