Abstract
The invention discloses a kind of oil pipe joint, it is characterized in that: oil connection includes that both sides connect end and middle transition end, connect end in the both sides of described oil connection and be respectively equipped with the surface connecting end tube wall of a wedge being embedded on described tube wall, the upper surface of described wedge and described oil connection on an arc surface；The lower end of described wedge is fixed with trace, and the other end of described trace is fixed with screw that is that be arranged on described oil connection middle transition end and that pass described oil connection middle transition end.The present invention has a simple in construction, good sealing effect, the advantage such as practical.
Description
Technical field
The present invention relates to a kind of oil connection, specifically a kind of oil pipe joint.
Background technology
Usually can run into the situation of two oil pipe docking when installing or extend oil circuit, how by two oil pipes
It is securely attached to together, how to prevent side leakage, be all problems faced.In prior art, jointing
Form varied, it is necessary to providing a kind of simple in construction, the rational joint of cost solves problem.
Summary of the invention
According to technical problem set forth above, and provide a kind of oil pipe joint.The present invention mainly utilizes wedge
Shape block and the cooperation of trace, thus play the effect tightening connection.The technological means that the present invention uses is as follows:
A kind of oil pipe joint, it is characterised in that: oil connection includes that both sides connect end and middle transition end,
Connect end in the both sides of described oil connection and be respectively equipped with a wedge being embedded on described tube wall, described wedge
The surface connecting end tube wall of the upper surface of shape block and described oil connection is on an arc surface；Described wedge shape
The lower end of block is fixed with trace, the other end of described trace be arranged on described oil connection middle transition
That hold and through described oil connection middle transition end screw is fixed.
Preferably, the diameter of the middle transition end of described oil connection is more than the connection end of described oil connection
Diameter.
Preferably, described oil connection, described wedge, described screw and described trace are rustless steel
Material.
Compared with the prior art, the wedge of present invention employing and trace and the cooperation of screw, be by spiral shell
When nail is screwed in joint, wedge is tilted by trace, props up tube inner wall to be connected, thus reaches
The effect tightened.
Accompanying drawing explanation
The present invention is further detailed explanation with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
In figure: 1, oil connection 2, wedge 3, screw 4, trace
Detailed description of the invention
The present invention provides a kind of oil pipe joint, makees technical scheme into one below in conjunction with the accompanying drawings
Step explanation.
As it is shown in figure 1, a kind of oil pipe joint, oil connection 1 includes that both sides connect end and middle transition
End, connects end and is respectively equipped with a wedge being embedded on described tube wall 2 in the both sides of described oil connection 1,
The surface connecting end tube wall of the upper surface of described wedge 2 and described oil connection 1 is on an arc surface；
The lower end of described wedge 2 is fixed with trace 4, the other end of described trace 4 be arranged on described oil pipe
Joint 1 middle transition end and screw 3 through described oil connection 1 middle transition end fix.
The diameter of the middle transition end of described oil connection 1 is more than the diameter connecting end of described oil connection 1.
Described oil connection 1, described wedge 2, described screw 3 and described trace 4 are stainless steel
Matter.
Compared with the prior art, the wedge of present invention employing and trace and the cooperation of screw, be by spiral shell
When nail is screwed in joint, wedge is tilted by trace, props up tube inner wall to be connected, thus reaches
The effect tightened.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention not office
Being limited to this, any those familiar with the art is in the technical scope that the invention discloses, according to this
The technical scheme of invention and inventive concept thereof in addition equivalent or change, all should contain the protection in the present invention
Within the scope of.
