Abstract
The invention discloses a kind of Leak-proof 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 a wedge being embedded on described tube wall, the upper surface of described wedge is provided with the surface connecting end tube wall of seal washer, the upper surface of described wedge and described oil connection on an arc surface；The lower end of described wedge is fixed with trace, 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, and the position that described screw contacts with the tube wall of described oil connection middle transition end is provided with O-ring seals.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 Leak-proof 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 Leak-proof oil pipe joint.
The technological means that the present invention uses is as follows:
A kind of Leak-proof oil pipe joint, it is characterised in that: oil connection 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, institute in the both sides of described oil connection
The upper surface stating wedge is provided with the connection of seal washer, the upper surface of described wedge and described oil connection
The surface of end tube wall is on an arc surface；The lower end of described wedge is fixed with trace, described trace
The other end be arranged on described oil connection middle transition end and through described oil connection middle transition
The screw of end is fixed, and the position that described screw contacts with the tube wall of described oil connection middle transition end is provided with O
Shape sealing ring.
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.
Preferably, the position of the wedge on two both sides connection end tube walls being arranged on described oil connection becomes
180 ° relatively.
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 design of sealing ring is possible to prevent oil to ooze out in screw hole, the additionally sealing on wedge
Packing ring is also to prevent tubing leak further.
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 5, seal washer 6, O shape
Sealing ring
Detailed description of the invention
The present invention provides a kind of Leak-proof oil pipe joint, below in conjunction with the accompanying drawings technical scheme is made into
One step explanation.
As it is shown in figure 1, a kind of Leak-proof oil pipe joint, oil connection 1 includes that both sides connect end and middle mistake
Cross end, connect end in the both sides of described oil connection 1 and be respectively equipped with a wedge being embedded on described tube wall 2,
The upper surface of described wedge 2 is provided with seal washer 5, the upper surface of described wedge 2 and described oil connection
The surface connecting end tube wall of 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 connection 1 middle transition end and through described oil
The screw 3 of pipe joint 1 middle transition end is fixed, described screw 3 and described oil connection 1 middle transition end
Tube wall contact position be provided with O-ring seals 6.
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.
Two both sides being arranged on described oil connection 1 connect the position one-tenth 180 ° of the wedge 2 on end tube wall
Relatively.
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 design of sealing ring is possible to prevent oil to ooze out in screw hole, the additionally sealing on wedge
Packing ring is also to prevent tubing leak further.
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.
