Abstract
The utility model discloses a type connecting rod dust cover seals, including ball round pin seal port, dustproof cover body wall and ball key seat seal port, the dustproof cover body wall is flat cover body wall, and ball round pin seal port exit end is equipped with and seals the cover on the dustproof cover body wall, and the maximum diameter department on dustproof cover body wall outer wall is equipped with the die parting line circle. The utility model discloses ball round pin seal port exit end is equipped with and seals the cover on the dustproof cover body wall, and it becomes the one -level dust cover to seal the cover, and dustproof effect obtains the reinforcing, and is simple and efficient during the use, the fracture of dust cover inner wall can be avoided to the die parting line circle when vulcanization molding, improve the quality of dust cover, prolongs the life of dust cover, improves effect dustproof, muddy water preventing.
Description
Technical field
This utility model belongs to manufactruing equipment of automobile technical field, relates to a kind of rubber seal, is specifically related to a kind of sealing type connecting rod dust cover.
Background technology
In the power unit of motor vehicles, between the connector of motion transmission, many employing dust covers carry out dust seal.Existing dust cover many employings natural rubber, the dust cover having in manufacturing process can produce slit cracking, and can produce some slits at rubber cracking, although sometimes with perusal less than, but in long-term fierce motor process, due to quality dissatisfaction；Dust cover meeting cracking failure, dust-proof effect is poor, and motion transmission is produced harmful effect.
Utility model content
For above-mentioned the deficiencies in the prior art, this utility model provides a kind of sealing type connecting rod dust cover.
The technical solution adopted in the utility model is:
A kind of sealing type connecting rod dust cover, including ball pin seal, dust cover body wall and ball pin seat seal, dust cover body wall is flat type cover body wall, and in dust cover body wall upper end, the ball pin seal port of export is provided with sealing cover, is provided with die parting line circle at the maximum gauge on dust cover body wall outer wall.
Further, this body wall thickness at the maximum gauge on dust cover body wall outer wall is minimum.
Further, the cross section of die parting line circle is circular arc type, and die parting line circle seamlessly transits with dust cover body wall junction.
Further, die parting line circle and sealing cover are same rubber global formation with dust cover body wall.
This utility model beneficial effect is obvious: (1) is provided with sealing cover at the dust cover body wall upper end ball pin seal port of export, and sealing cover becomes one-level dust cover, and dust-proof effect is strengthened, simple and efficient during use；(2) in dust cover main body, set die parting line circle, be avoided that the cracking of dust cover inwall when sulfidization molding, improve the quality of dust cover, extend the service life of dust cover, improve the effect of muddy water dust-proof, anti-.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference: ball pin seal 1, dust cover body wall 2, ball pin seat seal 3, die parting line circle 4, sealing cover 5.
Detailed description of the invention
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings, but, scope of the present utility model is not limited to following embodiment.
Embodiment 1
A kind of sealing type connecting rod dust cover, including ball pin seal 1, dust cover body wall 2 and ball pin seat seal 3, dust cover body wall 2 is flat type cover body wall, and ball pin seat seal 3 outer body wall is provided with fastening mounting groove.
In dust cover body wall 2 upper end, ball pin seal 1 port of export is provided with sealing cover 5, and sealing cover is strengthened as one-level dust cover, dust-proof effect.
I.e. it is provided with die parting line circle 4 at this body wall thickness minimum at maximum gauge on dust cover body wall 2 outer wall.This is in motion transmitting procedure, and local is easiest to be deformed, in practice it has proved that, the product sulfidization molding inwall having die parting line is the most easy to crack, and the product without die parting line has stealthy cracking, in use mostly, particularly in long-term fierce motor process, product breakage easy to crack.
The cross section of die parting line circle 4 is circular arc type, and die parting line circle 4 seamlessly transits with dust cover body wall junction.Die parting line circle 4 and sealing cover 5 are same rubber global formation with dust cover body wall 2.
The ball pin seal 1 of dust cover is connected with ball pin, and in ball pin seal, 1 is provided with two dust-proof profile of tooth circles, profile of tooth circle tooth depth 1mm.Ball pin seat seal 3 is fixed on ball pin seat by clip clamping.
