Abstract
The utility model relates to a turning-connection piece. The turning-connection piece comprises a first connecting part and a second connecting part. The first connecting part is provided with a thread installing hole, and the second connecting part is provided with annular grooves. The inner walls, located outside the annular grooves, of the second connecting parts are provided with annular seal grooves, and the bottom wall surfaces of the annular seal grooves are arranged into slopes. The second connecting part is provided with the two annular seal grooves, and the bottom surfaces of the annular seal grooves are concaved inwards with the central lines of the bottom surfaces as the axes. When the turning-connection piece is used, the parts, which are enlarged due to deformation, of the bottom portions of articles in the annular grooves can be contained in the bottom wall slopes of the annular seal grooves, and the articles can be unlikely to extrude the space formed by the annular grooves through the turning-connection piece. Seal rings can be arranged in the annular seal grooves during the turning-connection piece using process to play a sealing role, and therefore the overall sealing performance of the turning-connection piece is improved.
Description
Technical field
The utility model relates to a kind of interface unit, is a kind of adaptor with being specifically related to.
Background technique
Existing in prior art, the adaptor that a side is arranged to circular groove is therein in the process using, material in its circular groove, after using for a long time, under the impact of meeting because of series of physical effects such as being squeezed, and produces certain deformation in its bottom; Will push like this circular groove space of adaptor, this makes will produce slot in the time changing the material of same specification, has affected the sealing effect of adaptor entirety.
Model utility content
The utility model object is that a kind of adaptor is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of adaptor, comprise connect one be connected two, in one of described connection, be provided with threaded mounting hole, have circular groove on connecting two; Two of described connections are provided with annular seal groove on the inwall of the outside of circular groove, and its diapire face is arranged to inclined-plane.
Further, in two of described connections, be provided with two annular seal grooves, and the bottom surface of described annular seal groove is take its center line as axial sunken inside.
Further, the outer surface of two of described connections is arranged to circular-arc.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Adaptor described in the utility model, on outer side wall due to circular groove, be provided with annular seal groove and diapire face is arranged to inclined-plane, this makes this adaptor in the process using, its bottom of material set in its circular groove can be held by circular groove diapire inclined-plane because of the part that distortion increases, and is unlikely to push the space that the circular groove of this adaptor forms; In the process that the annular seal groove being simultaneously provided with can use at adaptor, seal ring is set, to play effect of sealing, and then has improved adaptor overall sealing performance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The sectional view that accompanying drawing 1 is adaptor described in the utility model;
Wherein: 1, connect one; 2, connect two; 3, threaded mounting hole; 4, circular groove; 5, annular seal groove; 6, inclined-plane.
embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
In two 2 of wherein said connections, be provided with two annular seal grooves 5, and the bottom surface of described annular seal groove 5 is take its center line as axial sunken inside; The outer surface that described connection is two 2 is arranged to circular-arc.
Adaptor described in the utility model is in the process using, if the interior set material of its circular groove 4 is under a series of External Force Actings such as extruding, its bottom produces distortion and the part that increases can be held by the inclined-plane 6 of circular groove 4 diapires, is unlikely to push the space that the circular groove 4 of this adaptor forms; In the process that the annular seal groove 5 being simultaneously provided with can use at adaptor, seal ring is set, to play effect of sealing, and then has improved adaptor overall sealing performance.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
