Further, the outside of described male connection is provided with spacing ring block；Conflict in described female adapter end
On spacing ring block.
Further, described spacing ring block is provided with the first inclined plane；The first described inclination faces out nipple
The connection toroidal direction of end tilts.
Further, described female adapter end is provided with the second inclined plane；Described second inclined plane and the first inclined plane
Conflict and connect.
Further, the second described inclined plane is consistent with the incline direction of the first inclined plane.
Further, the second described inclined plane includes contacting inclined-plane and connects inclined-plane；Described connection inclined-plane is located at contact
The inner side on inclined-plane；The incline direction of described contact inclined-plane and the first inclined plane is always；Described connection inclined-plane with contact inclined-plane
Incline direction contrary.Form annular space between described connection inclined-plane, the first inclined plane and male connection lateral surface.
Further, the inner side on described connection inclined-plane is provided with support ring block；Outside described support ring block and male connection
Side reclines.
Further, the longitudinal cross-section structure triangular in shape of described support ring block.
Further, it is provided with sealing ring in described detent.
Beneficial effects of the present invention
1. extend a connection anchor ring in male connection end to inner side, the positioning of annular is set on connecting anchor ring
Groove；The interface channel of one truncated cone-shaped structure is extended on the inwall of female adapter, the outboard end of interface channel is inserted
It is connected in the detent connecting on anchor ring.The cooperation grafting of the outboard end of interface channel and detent makes male connection
Disperseed with the carrying of the threaded connection place of female adapter.And the inwall of female adapter, connect anchor ring, connect logical
Longitudinal sectional view that road these three parts connect structure triangular in shape, using the stability of triangle, so that external screw thread connects
The connection of head and female adapter is more firm.
2. the outside in male connection is provided with spacing ring block, is conflicted in spacing ring block in female adapter end
On.Can be conflicted to due to the rotation of screw thread spacing ring block in female adapter end first, spacing ring block also can internal spiral shell
Stricture of vagina fitting end produces an active force, the axial load power of dispersion male connection and female adapter, makes male connection
More firm with what female adapter connected.
3. spacing ring block is provided with the first inclined plane, and first tilts to face out nipple end direction tilts.So
Structure make between male connection and female adapter produce radial force, 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 are conflicted and connected.Such
Structure further increases generation radial force between male connection and female adapter, and dispersion male connection and female thread connect
The axial load of head.
5. the second inclined plane includes contacting inclined-plane and connects inclined-plane, connects the inner side located at contact inclined-plane for the inclined-plane；Contact is tiltedly
The incline direction of face and the first inclination always, connects inclined-plane contrary with the incline direction contacting inclined-plane.Such structure makes interior spiral shell
Producing space between stricture of vagina fitting end and male connection lateral surface, thus decreasing the weight of female adapter end, making outer
Nipple is more prone to the effect that internal threads joint produces radial force, further increases male connection and female thread connects
The steadiness of head, the axial load of also further dispersion male connection and female adapter simultaneously.
6. the inner side connecting inclined-plane arranges a support ring block, and support ring block and male connection lateral surface recline.Support
The effect of ring block setting is so that the radial forces that male connection internal threads joint produces fully is postponed to male connection
With the threaded connection place of female adapter, disperse the axial load power of male connection and female adapter, increased external screw thread
Joint and the stability of female adapter connection.
7. sealing ring is set in detent, increased the sealing between male connection and female adapter.
