Existing ball-joint is divided into bulb pin-type and the two different structures of spherical surface pin-type.Existing bulb pin assembly such as China
Patent document data discloses a kind of automobile pull rod joint mechanism [application number: 200920005436.4 of proposition；Authorization Notice No.:
201330794 Y of CN], including ball rod, dust cover, bulb circle, circlip, rod head, ball seat, end cap formed, end cap peace
Lower position loaded on rod head, end cap top are equipped with ball seat, and ball rod is installed in rod head and connects with ball seat
It touches, bulb circle is installed in the middle part of ball rod, dust cover is installed, dust cover is fixed by circlip between ball rod and rod head
In on rod head, the material of ball seat is nitrile rubber.
In above-mentioned automobile pull rod joint mechanism, it is dust-proof that ball rod has certain probability appearance in limit swing process
Cover the phenomenon that falling off, and dust cover falls off and will lead to external dust and contact with bulb, accelerates bulb to wear, aging.
Utility model content
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of ball stud, solution
Technical problem is how to prevent dust cover from falling off.
The purpose of this utility model can be realized by the following technical scheme: a kind of ball stud, including pin rod and bulb, pin
The both ends of bar are respectively thread segment and the conical section for being connected with bulb, and pass through arc transition between conical section and bulb,
It include the cylindrical section for being connected with conical section in the middle part of the pin rod, which is characterized in that clamping is cased with outside the pin rod
Set, inner sidewall of the gripping sleeve close to one end of bulb is the conical surface to match with conical section, and gripping sleeve passes through the conical surface and taper
The mode of section tight abutment is fixedly connected with pin rod, and the other end of the gripping sleeve is positioning region annular in shape, positioning region with
Cylindrical section faces, and clamp port annular in shape is formed between positioning region and cylindrical section.
When actual assembled, there is one section of interconnecting piece annular in shape, and interconnecting piece is clamped in clamp port on dust cover.
Clamp port clamping part dust cover falls off in the bonding strength of enhancing dust cover and pin rod to avoid dust cover same
When, and the compactness that dust cover is contacted with pin rod can be reinforced, the sealing effect that Lai Tigao dust cover is connected with pin rod, to ensure ball
The normal rotation of head.
Secondly, the conical surface and conical section tight abutment will form reliable sealing, and clamp port and the conical surface are coaxial arrangement again,
Sealed pathway can be extended in this way, to further increase the leakproofness that dust cover is connected with pin rod, turned to further increase bulb
Dynamic stability.
In above-mentioned ball stud, integrally formed with annular plush copper on the inner sidewall of the positioning region, and annular plush copper
It is coaxially disposed with positioning region.In the case where positioning region compresses effect, the compactness of dust cover and pin rod contact can further improve.
In above-mentioned ball stud, the annular plush copper is distributed there are two and along the axial direction of positioning region.
In above-mentioned ball stud, section of the annular plush copper in the axial direction of positioning region is arc-shaped.
Compared with prior art, this ball stud has the advantage that
1, clamp port clamping part dust cover falls off in the bonding strength of enhancing dust cover and pin rod to avoid dust cover
Meanwhile and the compactness that dust cover is contacted with pin rod, the sealing effect that Lai Tigao dust cover is connected with pin rod, to ensure can be reinforced
The normal rotation of bulb.
2, the conical surface and conical section tight abutment will form reliable sealing, and clamp port and the conical surface are coaxial arrangement again, this
Sample can extend sealed pathway, to further increase the leakproofness that dust cover is connected with pin rod, to further increase bulb rotation
Stability.
