Detailed Description
As shown in fig. 1, fig. 1 is a schematic structural view of a double-sealed trachea quick connector according to the present invention.
Referring to fig. 1, the utility model provides a double containment trachea quick connector, include: the joint comprises a joint body 1, a main sealing ring 2, a retaining ring 3 and an auxiliary sealing ring 4;
connect 1 middle part of body to be equipped with trachea installation passageway, trachea installation passageway inner wall is equipped with along the first annular mounting groove of circumference extension, and main sealing washer 2 seal installation is in first annular mounting groove, and retaining ring 3 is located just be located 2 one sides of main sealing washer in the first annular mounting groove, and 3 inner walls of retaining ring are equipped with second annular mounting groove, and supplementary sealing washer 4 is located in the second annular mounting groove.
In the double-sealed trachea quick connector's of this embodiment concrete using-way, receive trachea 10's lateral pressure when connecting the body, the retaining ring has played the tracheal effect of stabilizing, bears trachea 10's lateral pressure for the atress is even between sealing washer and the trachea outer wall, simultaneously, guarantees main sealing washer and auxiliary seal circle and trachea 10's sealing connection reliable and stable, makes sealed the best user state that keeps all the time.
In this embodiment, the double-sealed trachea quick connector that proposes connects body middle part and is equipped with trachea installation passageway, trachea installation passageway inner wall is equipped with along the first annular mounting groove of circumference extension, and main sealing washer and retaining ring are located in the first annular mounting groove, and the retaining ring is located main sealing washer one side, and the retaining ring inner wall is equipped with the second annular mounting groove, and supplementary sealing washer is located in the second annular mounting groove. Through the quick connector of trachea of above-mentioned double containment of optimal design, through setting up retaining ring and auxiliary seal circle for main sealing washer, on the one hand, retaining ring and auxiliary seal circle play the effect firm to the trachea jointly, and on the other hand effectively gets rid of trachea surface adnexed debris through auxiliary seal circle during the installation, prevents that adnexed debris from influencing the sealed effect of main sealing washer on the trachea.
In a specific embodiment, the first annular mounting groove extends from the inner wall of the opening at one end of the air pipe mounting channel to the middle part along the axial direction, and the main sealing ring 2 is positioned at one side of the retaining ring 3 away from the opening; the main sealing ring and the retaining ring are positioned at an opening of an insertion end of the annular mounting groove, in a specific mounting mode, the air pipe 10 is inserted into the mounting channel from the opening of the insertion end of the connector body, in the mounting process, the air pipe 10 firstly penetrates through the retaining ring and the auxiliary sealing ring positioned in the middle of the retaining ring, sundries attached to the surface of the air pipe 10 are blocked outside the mounting channel by the auxiliary sealing ring, and then the air pipe 10 enters the main sealing ring, so that the sealing effect of the main sealing ring is prevented from being influenced by sundries on the air pipe 10, and the air leakage.
