Problems solved by technology

[0002] In the prior art, during the use of the adapter piece with an annular groove on one side, the material in the annular groove will be crushed due to a series of physical effects such as extrusion after a long period of use. Under the influence, a certain deformation will be produced at the bottom; this will squeeze the annular groove space of the adapter, which will cause gaps when the material of the same specification is replaced, affecting the overall sealing effect of the adapter

Abstract

The invention discloses 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 threaded mounting hole, and the second connecting part is provided with an annular groove. An annular sealing groove is formed in the inner wall of the outer side of the annular groove of the second connecting part, and the bottom wall face of the annular sealing groove is arranged to be an inclined plane. The second connecting part is provided with two annular sealing grooves, and the bottom faces of the annular sealing grooves are recessed inwards by using the center lines of the annular sealing grooves as the axial direction. When the turning-connection piece is used, the increased part caused by deformation of the bottom of an object arranged in the annular groove can be contained by the inclined plane of the bottom wall of the annular groove so that the space formed by the annular groove of the turning-connection piece can not be squeezed; meanwhile, the arranged annular sealing grooves can be provided with sealing rings in the using process of the turning-connection piece, a sealing effect is achieved, and thus the overall sealing property of the turning-connection piece is improved.

Description

technical field [0001] The invention relates to a connecting device, in particular to an adapter. Background technique [0002] In the prior art, during the use of the adapter piece with an annular groove on one side, the material in the annular groove will be crushed due to a series of physical effects such as extrusion after a long period of use. Under the influence, a certain deformation occurs at the bottom; this will squeeze the annular groove space of the adapter, which will cause gaps when the material of the same specification is replaced, affecting the overall sealing effect of the adapter. Contents of the invention [0003] In view of the above-mentioned existing technical problems, the object of the present invention is to propose an adapter. [0004] The technical solution of the present invention is realized as follows: an adapter, including a connecting part and a connecting part, the connecting part is provided with a threaded mounting hole, and the connect...
