Description
Technical Field
The utility model relates to a plane seal structure for trachea is connected.
Background
The air pipe joint is widely applied to pneumatic systems of various machines. The existing air pipe joint is mainly a cutting sleeve type air pipe joint which is pressed and pulled out, but because an air pipe needs to be inserted into a pressing ring, the pressing ring can only be pressed when the pressing ring is pressed, the area which can be actually pressed by fingers or tools is small, the action of pulling out the air pipe while pressing is inconvenient, and the air pipe joint is particularly difficult when the air pipe joint is small; in addition, since the air pipe joint is often installed in various places, and in many cases, the space is limited, and when the air pipe joint is small, the action of pulling out the air pipe while pressing is more difficult.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the prior art, and providing a plane sealing structure which is used for connecting a trachea and does not need to be pressed.
A plane sealing structure for connecting air pipes comprises a gas pipeline, a sealing sleeve, a cutting sleeve and an air pipe, wherein the end part of the gas pipeline is provided with an external thread, one end of the cutting sleeve is provided with an internal thread hole matched with the external thread, the other end of the cutting sleeve is provided with a section of conical hole, the conical hole is communicated with the internal thread hole, the diameter of the conical hole is small outside and large inside, the sealing sleeve is arranged between the cutting sleeve and the gas pipeline, the sealing sleeve is divided into a head part and a tail part, the head part of the sealing sleeve is contacted with the gas pipeline, the head part of the sealing sleeve is an arc-shaped end surface, the tail part of the sealing sleeve is a neck-shaped structure, the outer surface of the neck-shaped structure is an arc-shaped surface, the arc-shaped surface of the neck-shaped structure is contacted with the inner surface of the conical hole, the inner surface of the neck-shaped structure is provided with a groove, the diameter of the tail part of the sealing sleeve is larger than the, and is smaller than the major diameter of the taper hole, and the air pipe is clamped at the groove on the inner surface of the neck-shaped structure through the air pipe joint.
As a further improvement, the shape of the cutting sleeve is a regular hexagon.
As a further improvement, the cutting sleeve is made of stainless steel.
As a further improvement, the sealing sleeve is made of red copper.
As a further improvement, the outer diameter of the air pipe joint is less than or equal to the tail diameter of the sealing sleeve.
As a further improvement, the connection mode of the air pipe and the air pipe joint is integrally formed.
Has the advantages that:
the utility model relates to an it is ingenious, used the design that metal seal circle has replaced O type circle, avoided O type circle ageing and aroused gas leakage, simple to operate, the structure is firm.

Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
As shown in figure 1, the plane sealing structure for the connection of the air pipe comprises an air pipe 1, a cutting sleeve 2, a sealing sleeve 3, an air pipe joint 4 and an air pipe 5.
A plane sealing structure for connecting a trachea comprises a gas pipeline 1, a sealing sleeve 3, a cutting sleeve 2 and a gas pipe 5, wherein an external thread is arranged at the end part of the gas pipeline 1, an internal thread hole matched with the external thread is arranged at one end of the cutting sleeve 2, a section of conical hole is arranged at the other end of the cutting sleeve 2, the conical hole is communicated with the internal thread hole, the diameter of the conical hole is small outside and large inside, the cutting sleeve 2 is in a regular hexagon shape, the cutting sleeve 2 is made of stainless steel, the sealing sleeve 3 is arranged between the cutting sleeve 2 and the gas pipeline 1, the sealing sleeve 3 is made of red copper, the sealing sleeve 3 is divided into a head part and a tail part, the head part of the sealing sleeve 3 is contacted with the gas pipeline 1, the head part of the sealing sleeve 3 is an arc-shaped end surface, the tail part of the sealing sleeve 3 is in a neck-shaped structure, the outer surface of the, the diameter of seal cover 3's afterbody is greater than the path of bell mouth, and is less than the major diameter of bell mouth, and trachea 5 passes through the groove of 4 joint at the neck-shaped structure internal surface of trachea joint, and the external diameter of trachea joint 4 is less than or equal to seal cover 3's afterbody diameter, and trachea 5 and trachea joint 4's connected mode are integrated into one piece.
During the use, put sealing washer 3 into cutting ferrule 2 to in the recess of 3 afterbody of seal cover with trachea joint 4 embedding, begin to screw up the screw thread after that, because of the effect of power, the afterbody of seal cover 3 can receive the pressure of bell mouth and inwards contract, simultaneously chucking trachea joint 4 reaches a sealed effect, the arcwall face of 3 afterbodies of seal cover extrudees with the internal surface of bell mouth mutually and forms sealed face, the arc terminal surface of 3 heads of seal cover extrudees mutually with the terminal surface of gas pipeline 1 and forms sealed face, trachea 5 is connected and is accomplished.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
