Abstract
The utility model relates to a bearing movable joint, comprising a first joint, a second joint and a fixed nut, wherein the first joint and the second joint are coaxially arranged and respectively in threaded connection with the fixed nut; one end of the first joint, corresponding to the second joint, is provided with an inwards-concave conical surface; one end of the second joint, corresponding to the first joint, is provided with an outwards-convex circular arc-shaped surface; and the conical surface of the first joint pushes against the circular arc-shaped surface of the second joint. According to the technical scheme, the conical surface of the first joint pushes against the circular arc-shaped surface of the second joint, and the sealing performance of the first joint and the second joint is improved, so that the bearing movable joint cannot leak water easily in the use process.
Description
Technical field
The utility model relates to a kind of union of accepting.
Background technique
Accept union, generally include the first joint, the second joint and set screw nut, the first joint, the second joint are coaxial setting and are threaded with set screw nut respectively, and there is the shortcoming that sealability is bad, leak easily in traditional union of accepting.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of sealability is better, antileaking accept union.
For achieving the above object, the utility model provides following technological scheme: a kind ofly accept union, comprise the first joint, the second joint and set screw nut, the first joint, the second joint are coaxial setting and are threaded with set screw nut respectively, corresponding the second joint one end of described the first joint is provided with the conical surface of indent, corresponding the first joint one end of described the second joint is provided with the arc surface of evagination, the setting that offsets of the arc surface of the conical surface of described the first joint and described the second joint.
By adopting technique scheme, because the conical surface of the first joint and the arc surface of the second joint offset, improved the sealability between the first joint, the second joint, so that accept in use antileaking of union.
The utility model further arranges: described the second joint is corresponding to be provided with the second joint step with the set screw nut link position, and described set screw nut is corresponding to be provided with the set screw nut step suitable with the second joint step with the second joint link position.
By adopting technique scheme, improved the sealability between the second joint and the set screw nut, further so that accept in use antileaking of union.
The utility model further arranges: described the first joint and the second joint are respectively arranged with the first joint passage and the second joint passage, the internal diameter of corresponding the second joint one end of described the first joint passage is less than the first joint passage the other end internal diameter, and the internal diameter of corresponding the first joint one end of described the second joint passage is less than the second joint passage the other end internal diameter.
By adopting technique scheme, so that when accepting union and being connected with pipeline, accept and have better sealing effect between union and the pipeline.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model example structure sectional view.
Embodiment
Referring to accompanying drawing 1, the utility model is disclosed accepts union, comprise the first joint 1, the second joint 2 and set screw nut 3, the first joint 1, the second joint 2 are coaxial setting and are threaded with set screw nut 3 respectively, described the first joint 1 corresponding the second joint 2 one ends are provided with the conical surface 11 of indent, described the second joint 2 corresponding the first joint 1 one ends are provided with the arc surface 21 of evagination, the setting that offsets of the arc surface 21 of the conical surface of described the first joint 1 11 and described the second joint 2.By adopting technique scheme, because the conical surface 11 of the first joint 1 and the arc surface 21 of the second joint 2 offset, improved the sealability between the first joint 1, the second joint 2, so that accept in use antileaking of union.
Present embodiment further arranges: described the second joint 2 is corresponding to be provided with the second joint step 22 with set screw nut 3 link positions, and described set screw nut 3 is corresponding to be provided with the set screw nut step 31 suitable with the second joint step 22 with the second joint 2 link positions.So arrange, improved the sealability between the second joint 2 and the set screw nut 3, further so that accept in use antileaking of union.
Present embodiment further arranges: described first connect 1 with the second joint 2 be respectively arranged with the first joint passage 12 and the second joint passage 23, the internal diameter of described the first joint passage 12 corresponding the second joint 2 one ends is less than the first joint passage 12 the other end internal diameters, and the internal diameter of described the second joint passage 23 corresponding the first joint 1 one ends is less than the second joint passage 23 the other end internal diameters.So arrange, so that when accepting union and being connected with pipeline, accept and have better sealing effect between union and the pipeline.
Claims (3)
