Abstract

The invention discloses a leak-proof oil pipe joint. The oil pipe joint is characterized by comprising two-side connection ends and a middle transition end, wherein wedge blocks embedded into pipe walls are respectively arranged at the two-side connection ends and are provided with sealing washers on the upper surfaces; the upper surfaces of the wedge blocks and the surfaces of the pipe walls of the oil pipe joint are in the same circular arc face; linkage rods are fixed at the lower ends of the wedge blocks, and the other ends of the linkage rods are fixed with screws formed at and penetrating the middle transition end of the oil pipe joint; and O-shaped seal rings are arranged in the contact positions of the screws and the middle transition end of the oil pipe joint. The oil pipe joint has the advantages of simple structure, good sealing effect, high practicability and the like.

Description

The Anti-leakage type oil connection
Technical field
The present invention relates to a kind of oil connection, specifically a kind of Anti-leakage type oil connection.
Background technique
Usually can run into the situation with two oil pipe docking when installing or prolong oil circuit, how two oil pipes firmly be linked together, how prevent side leakage, all be the problem that faces.In the prior art, the form of jointing is varied, is necessary to provide a kind of simple in structure, and the rational joint of cost is dealt with problems.
Summary of the invention
According to the technical problem of above-mentioned proposition, and provide a kind of Anti-leakage type oil connection.
The technological means that the present invention adopts is as follows:
A kind of Anti-leakage type oil connection, it is characterized in that: oil connection comprises both sides connecting end and middle transition end, be respectively equipped with a wedge-shaped blocks that is embedded on the described tube wall at the both sides of described oil connection connecting end, the upper surface of described wedge-shaped blocks is provided with seal washer, and the surface of the connecting end tube wall of the upper surface of described wedge-shaped blocks and described oil connection is on an arc surface; The lower end of described wedge-shaped blocks is fixed with continuous motion stem, the other end of described continuous motion stem be arranged on screw described oil connection middle transition end and that pass described oil connection middle transition end and fix, described screw is provided with O-ring seals with the position that the tube wall of described oil connection middle transition end contacts.
Preferably, the diameter of the middle transition end of described oil connection is greater than the diameter of the connecting end of described oil connection.
Preferably, described oil connection, described wedge-shaped blocks, described screw and described continuous motion stem are stainless steel.
Preferably, the position of the wedge-shaped blocks on two both sides connecting end tube walls that are arranged on described oil connection becomes 180 ° relatively.
Compare than prior art, the wedge-shaped blocks that the present invention adopts and the cooperation of continuous motion stem and screw are when being screwed into screw in the joint, and wedge-shaped blocks props up the tube inner wall that will connect by the continuous motion stem perk, thereby reaches the effect of tightening; The design of seal ring can prevent that oil from oozing out in screw hole, the seal washer on the wedge-shaped blocks also is further to prevent tubing leak in addition.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention.
Among the figure: 1, oil connection 2, wedge-shaped blocks 3, screw 4, continuous motion stem 5, seal washer 6, O-ring seals
Embodiment
The invention provides a kind of Anti-leakage type oil connection, below in conjunction with accompanying drawing technological scheme of the present invention is described further.
As shown in Figure 1, a kind of Anti-leakage type oil connection, oil connection 1 comprises both sides connecting end and middle transition end, be respectively equipped with a wedge-shaped blocks 2 that is embedded on the described tube wall at the both sides of described oil connection 1 connecting end, the upper surface of described wedge-shaped blocks 2 is provided with seal washer 5, and the surface of the connecting end tube wall of the upper surface of described wedge-shaped blocks 2 and described oil connection 1 is on an arc surface; The lower end of described wedge-shaped blocks 2 is fixed with continuous motion stem 4, the other end of described continuous motion stem 4 is fixed with being arranged on screw 3 described oil connection 1 middle transition end and that pass described oil connection 1 middle transition end, and described screw 3 is provided with O-ring seals 6 with the position that the tube wall of described oil connection 1 middle transition end contacts.
The diameter of the middle transition end of described oil connection 1 is greater than the diameter of the connecting end of described oil connection 1.
Described oil connection 1, described wedge-shaped blocks 2, described screw 3 and described continuous motion stem 4 are stainless steel.
The position of the wedge-shaped blocks 2 on two both sides connecting end tube walls that are arranged on described oil connection 1 becomes 180 ° relatively.
Compare than prior art, the wedge-shaped blocks that the present invention adopts and the cooperation of continuous motion stem and screw are when being screwed into screw in the joint, and wedge-shaped blocks props up the tube inner wall that will connect by the continuous motion stem perk, thereby reaches the effect of tightening; The design of seal ring can prevent that oil from oozing out in screw hole, the seal washer on the wedge-shaped blocks also is further to prevent tubing leak in addition.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technological scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
