Abstract
The utility model relates to a pipe joint which can adjust angles. The pipe joint comprises a lock nut and a spherical joint and is characterized in that the contact surface of the lock nut and the spherical joint is heaved outwards to form a circle of arc barbs; the contact surface of the spherical joint and the lock nut is concaved inwards to form a circle of arc covers, thus leading the contact surface of the lock nut and the spherical joint to form concentric spherical contact. The contact surface of the spherical joint and the lock nut is the concentric spherical contact, so the spherical joint and the lock nut can be oppositely rotated after the lock nut is connected with a joint body which connects the pipes by screw threads, which achieves the purpose that the pipe joint can adjust the angles of the connecting line connected; the pipe joint can be widely used in various occasions of transporting pressure gas and liquid and etc.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly about a kind of pipe joint of angle adjustable.
Background technique
At present, NBS can not be adjusted angle with the ball-type pipe joint that railroad industry standard (for example TB/T333 " ball-type pipe joint ") is used after being connected.This is because the surface of contact 3,4 between locking nut 1 and the ball-type joint 2 is the plane (as shown in Figure 1) perpendicular to axis, with after the fittings body 7 that is connected pipeline 6 is connected, two pipelines 5,6 can not relatively rotate angle to the ball-type joint 2 that is connected with pipeline 5 by locking nut 1.Therefore in use have at least possibility following problem to occur: 1, assembling is made troubles to pipeline, even can't assemble.2, the pipeline stress that produces that expands with heat and contract with cold can not discharge, and distortion and fracture occur.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of pipe joint of angle adjustable.
For achieving the above object, the utility model is taked following technological scheme: a kind of pipe joint of angle adjustable, comprise a locking nut and a ball-type joint, it is characterized in that: with the surface of contact of described locking nut and described ball-type joint to outer lug, form a circle arc barb, the surface of contact of described ball-type joint and described locking nut is concaved, form a circle arc cover, make the described locking nut and the surface of contact of described ball-type joint form a homocentric sphere face and contact.
Ball-type joint of the present utility model is that a homocentric sphere face contacts with the surface of contact of locking nut, therefore when the fittings body of locking nut and desire connecting pipeline by after being threaded, can relatively rotate between ball-type joint and the locking nut, realize that the utility model can adjust the purpose of connected tube road angle.The utility model can be widely used in various occasions such as feeds air under pressure and liquid.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 2, the utility model comprises a locking nut 1 and a ball-type joint 2, and the utility model to outer lug, forms a circle arc barb with the surface of contact 5 of locking nut 1 and ball-type joint 2, the surface of contact 4 of ball-type joint 2 with locking nut 1 concaved, form a circle arc cover; An one circle arc barb and a circle arc cover are a homocentric sphere face, can rotate contact relative to slyness.When with locking nut 1 of the present utility model and connected fittings body 7 by after being threaded, the pipeline 5 that is connected on the ball-type pipe joint 2 can relatively rotate (as shown in Figure 3) with the pipeline 6 that is connected on the fittings body 7 in certain angle [alpha] scope, thereby reaches the purpose that can adjust the pipeline angle.Two connected pipelines 5,6 can be welded on respectively on ball-type joint 2 and the fittings body 7.
