It easily loosens, the good wear-resisting reinforcing reducer union of structural stability.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of wear-resisting reinforcement type reducer union, including reducer union ontology, the reducer union bodies top are equipped with internal thread,
Bottom is equipped with outer silk, and middle part axially penetrates through a channel, inner sleeve is additionally provided at the top of the channel, between the inner sleeve and internal thread
Link slot is formed, the top of the outer surface of the reducer union ontology is equipped with several first pressure arms, and first pressure arm passes through torsion
Turn spring and reducer union ontology is rotatablely connected, the free end of first pressure arm is equipped with the first pressure head；The reducer union sheet
The middle part of the outer surface of body is equipped with several second pressure arms, and second pressure arm is connected by torsionspring and the rotation of reducer union ontology
It connecing, the free end of second pressure arm is equipped with the second pressure head, and first pressure arm pressurizes to the top-direction of reducer union ontology,
Second pressure arm pressurizes to the bottom direction of reducer union ontology.
As an improved technical scheme, first pressure arm and the second pressure arm are bending, the length of first pressure arm
Spend the length less than the second pressure arm.
As an improved technical scheme, the inner sleeve top is cylindrical tube shape, and bottom is up-narrow and down-wide horn-like.
As an improved technical scheme, the thickness of the inner sleeve is uniform, thickness range 1-5mm.
As an improved technical scheme, first pressure head and the second pressure head are sphere, the internal diameter of first pressure head
Less than the internal diameter of the second pressure head.
As an improved technical scheme, the vertical range of the internal thread to inner sleeve is not less than 5mm.
As an improved technical scheme, the quantity of first pressure arm and the second pressure arm is equal, and quantitative range is 4-8
It is a.
The utility model has the following beneficial effects:
(1) a kind of wear-resisting reinforcement type reducer union provided by the utility model uses interior nested structure, can block fluid
For the infiltration and impact at screw thread, the abrasion at internal thread is greatly reduced；
(2) a kind of wear-resisting reinforcement type reducer union provided by the utility model, due to the buffer function and pressure arm of inner sleeve
The addition of structure can balance the twisting resistance between the screw thread formed when use, maintain integrally-built stability, prevent junction
Loosening；
(3) structure is simple, easy to use, and inner sleeve can according to need selection thickness, to be suitable for different size thickness
Threaded fitting has good promotion and application prospect.
