Beneficial effects of the present invention
1. extend a connection anchor ring to inner side in male connection end, the positioning of annular is set on connection anchor ring
Groove；Extend an interface channel for truncated cone-shaped structure on the inwall of female adapter, the end of interface channel is plugged on
In detent on connection anchor ring.The cooperation grafting of the end and detent of interface channel makes male connection and internal thread
The load force of the threaded connection place of joint is disperseed, i.e., a support is also functioned between the end of interface channel and detent
Effect.And inwall, connection anchor ring, the longitudinal sectional view of interface channel these three parts connection of female adapter are in triangle
The structure of shape, using the stability of triangle, so that the connection of male connection and female adapter is more consolidated.When even
The end for connecting road is inserted when in detent with the rotation of screw thread, because the outer ledge of detent is outwards rolled
Tiltedly, the incline direction of the outer ledge of interface channel is consistent with the incline direction of the outer ledge of detent, so connection is logical
The end in road can produce an inwardly angled power to detent, synthesis and decomposition knowledge according to power, inwardly angled power
So as to resolve into a radial load and axial force, radial load pass through the transition of annular clamping ring so as to play internal threads joint and
The radial direction of male connection screws effect, so as to reach the effect of radially locking, so that male connection and female adapter
Connection more consolidate.
2. spacing ring block is provided with the outside of male connection, female adapter end is contradicted in spacing ring block
On.Female adapter end first can contradict spacing ring block due to the rotation of screw thread, and spacing ring block also can internal spiral shell
Line fitting end produces the axial load power of an active force, dispersion male connection and female adapter, makes male connection
More consolidated with what female adapter was connected.
3. spacing ring block is provided with the first inclined plane, and the first inclination faces out the inclination of nipple end direction.So
Structure make to produce radial load between male connection and female adapter, dispersion male connection and female adapter axial direction
Load.
4. female adapter end is provided with the second inclined plane, and the second inclined plane and the first inclined plane contradict connection.It is such
Structure further increases and radial load is produced between male connection and female adapter, and dispersion male connection and internal thread connect
The axial load of head.
5. the second inclined plane includes contact inclined-plane and connection inclined-plane, inner side of the connection inclined-plane located at contact inclined-plane；Contact is oblique
Always, connection inclined-plane is opposite with the incline direction on contact inclined-plane for face and the first inclined incline direction.Such structure makes interior spiral shell
Space is produced between line fitting end and male connection lateral surface, so as to reduce the weight of female adapter end, is made outer
Nipple is more prone to the effect that internal threads joint produces radial load, further increases male connection and internal thread connects
The steadiness of head, while the also further axial load of dispersion male connection and female adapter.
6. the inner side on connection inclined-plane sets a support ring block, and support ring block and male connection lateral surface recline.Support
The effect that ring block is set is that the radial forces for producing male connection internal threads joint are fully postponed to male connection
With the threaded connection place of female adapter, the axial load power of dispersion male connection and female adapter increased external screw thread
Joint and the stability of female adapter connection.
7. sealing ring is set in detent, the sealing between male connection and female adapter is increased.
