Abstract
The utility model relates to valve body equipment technical fields, especially a kind of high reliability ball pin assembly, compared with prior art, the high reliability ball pin assembly includes ball stud, bulb pin boss and end cap, the bulb guide is on bulb pin boss, end cap is covered in bulb pin boss rear end, and end cap is stuck on bulb pin boss by a circlip；An outer ring is additionally provided between ball stud and bulb pin boss, the outer surface of outer ring and the inner surface of bulb pin boss match；Across one layer of polymer plastic sarking between outer ring and ball stud, by the way that one layer of outer ring is arranged between ball stud and bulb pin boss, then one layer of polymer plastic sarking is embedded on outer ring again, it is engaged by polymer plastic sarking with ball stud, i.e. using flexible cooperation, the degree of wear of ball stud can be substantially reduced, the problem that effective solution ball stud and outer ring rigidity cooperate noise big has many advantages, such as that high reliablity, wearability are good, noise is small.
Description
Technical field
The utility model relates to valve body equipment technical field, especially a kind of high reliability ball pin assembly.
Background technique
Ball pin cooperation in the prior art is all rigidity cooperation, i.e., ball pin is directly engaged with ball pin shell, and use is this
Although structure structure is simple, manufacturing cost is low, due to being rigidity cooperation, it is prone to wear in long-term cooperation, Er Qieqiu
The noise that friction generates when pin uses is big, influences properties of product and service life.
Summary of the invention
For solve the problems, such as defect present in ball pin assembly in the prior art and, it is total to provide a kind of high reliability ball pin
At.
The utility model is that technical solution used by solving its technical problem is: a kind of high reliability of the utility model
Ball pin assembly includes ball stud, bulb pin boss and end cap, and on bulb pin boss, end cap is covered in bulb pin boss the bulb guide
Rear end, end cap are stuck on bulb pin boss by a circlip；An outer ring, outer ring are additionally provided between ball stud and bulb pin boss
Outer surface and the inner surface of bulb pin boss match；Across one layer of polymer plastic sarking, institute between outer ring and ball stud
The polymer plastic sarking stated by a protruding shaft be embedded in outer ring in be fixed on outer ring, the inner surface of polymer plastic sarking with
Ball stud matches, and the outer surface of polymer plastic sarking and the inner surface of outer ring match.
The cooperation outer end face of the ball stud and bulb pin boss is sealed cooperation by a polygon fold seals circle,
A locking steel wire is also cased with outside polygon fold seals circle.
The protruding projecting shaft of the ball stud, with unification adjustable nut on projecting shaft, adjustable nut outer end is logical
A bolt is crossed to be positioned.
The beneficial effects of the utility model are: compared with prior art, a kind of high reliability ball pin of the utility model is total
At by the way that one layer of outer ring is arranged between ball stud and bulb pin boss, one layer of polymer plastic backing strap is then embedded on outer ring again
Layer, is engaged by polymer plastic sarking with ball stud, i.e., using flexible cooperation, can substantially reduce ball stud
The problem that the degree of wear, effective solution ball stud and outer ring rigidity cooperate noise big, with high reliablity, wearability is good, makes an uproar
The advantages that sound is small.
Detailed description of the invention
A kind of high reliability ball pin assembly of the utility model is made with reference to the accompanying drawings and detailed description further
Explanation.
Fig. 1 is a kind of structural schematic diagram of high reliability ball pin assembly of the utility model.
Specific embodiment
As shown in Figure 1, a kind of high reliability ball pin assembly of the utility model includes ball stud 1, bulb pin boss 2 and end cap
3.1 set of ball stud on bulb pin boss 2, the protruding projecting shaft 4 of ball stud 1, on projecting shaft 4 with unification adjustable nut 5,
5 outer end of adjustable nut is positioned by a bolt 6.
As shown in Figure 1, end cap 3 is covered in 2 rear end of bulb pin boss, end cap 3 is stuck on bulb pin boss 2 by a circlip 7.
An outer ring 8 is additionally provided between ball stud 1 and bulb pin boss 2, the outer surface of outer ring 8 and the inner surface of bulb pin boss 2 match.
Across one layer of polymer plastic sarking 9 between outer ring 8 and ball stud 1, polymer plastic sarking 9 is embedded in by a protruding shaft 10
It is fixed on outer ring 8 in outer ring 8, inner surface and the ball stud 2 of polymer plastic sarking 9 match, polymer plastic sarking
The inner surface of 9 outer surface and outer ring 8 matches, i.e., polymer plastic sarking 9 is directly contacted with ball stud 1, is between the two
A kind of flexible cooperation, ball stud 1 carry out mediate contact by polymer plastic sarking 9 and outer ring 8 and bulb pin boss 2, avoid
Rigidity cooperation between the two.
As shown in Figure 1, the cooperation outer end face of ball stud 1 and bulb pin boss 2 carried out by a polygon fold seals circle 11 it is close
Envelope cooperation, is also cased with a locking steel wire 12, polygon fold seals circle 11 and polygon fold seals outside polygon fold seals circle 11
The setting of circle 11 and circlip 7 ensure that the leakproofness cooperated between ball stud 1 and bulb pin boss 2.
In conclusion compared with prior art, a kind of high reliability ball pin assembly of the utility model passes through in ball stud
One layer of outer ring is set between bulb pin boss, is then embedded in one layer of polymer plastic sarking on outer ring again, passes through polymer plastic
Sarking is engaged with ball stud, i.e., using flexible cooperation, can substantially reduce the degree of wear of ball stud, effectively
It solves the problems, such as that ball stud and outer ring rigidity cooperation noise are big, has many advantages, such as that high reliablity, wearability are good, noise is small.
The embodiment according to the present utility model description to being illustrated property of the utility model and not restrictive, but answer
Understand, the protection scope of the utility model is not limited thereto, and is not departing from relevant scope defined by the claims
In the case where, those skilled in the art can make change and/or modification, and should all cover the protection in the utility model
Within the scope of.
