Detailed Description
In order to better understand the technical solution of the present invention, the present invention will be described in detail through specific embodiments.
Refer to fig. 1-2. The utility model discloses a sealing washer structure of automobile-used quick-operation joint locates in quick-operation joint's female head to the setting is in conventional sealing washer groove.
The sealing ring 1 is ring-shaped. The male head 2 of the quick connector penetrates through the ring shape of the sealing ring 1 and is in sealing connection with the female head through the sealing ring 1.
The utility model discloses a sealing washer 1 has heterotypic section structure. The cross section profile of the sealing ring 1 along the axial direction is formed by connecting an arc line segment 14, a first straight line segment 13, a second straight line segment 12, a third straight line segment 11, a fourth straight line segment 16 and a fifth straight line segment 15 end to form a closed loop.
Refer to fig. 1-2. The sealing ring 11 is illustrated in a horizontal state. The arc line segment 14 on the cross-sectional profile of the seal ring 1 is located in the outer (outer ring side) direction of the seal ring 1. Wherein, an imaginary circle 10 can be formed by the two ends of the arc segment 14 extending outwards. I.e. the arc segments 14 are on the circumference of an imaginary circle 10 coinciding therewith. A first end point (shown as an upper end point) of the arc segment 14 is located on the horizontal centerline b of the imaginary circle 10, and a second end point of the arc segment 14 is located on the vertical centerline a of the imaginary circle 10.
The circumference of the imaginary circle 10 may coincide with the cross-sectional profile of a conventional "O" ring.
The first straight line segment 13 is vertically located at the outer side of the seal ring 1, and a first end point (shown as a lower end point) of the first straight line segment 13 is connected to a first end point of the arc segment 14. The first straight line segment 13 is tangent to the imaginary circle 10 at a first end point of the circular arc segment 14.
The second straight section 12 is horizontally oriented on the insertion side (toward the outside of the female) of the male 2. A first end point (shown as the right end point) of the second straight line segment 12 connects to a second end point of the first straight line segment 13.
The third straight line segment 11 is located at the inner side (inner ring side) orientation of the seal ring 1. The first end point (shown as the upper end point) of the third straight line segment 11 is connected to the second end point of the second straight line segment 12. The third straight line segment 11 is disposed obliquely toward the insertion side of the male 2.
The fourth straight section 16 is vertically positioned at the inner side of the sealing ring 1, and a first endpoint (shown as an upper endpoint) of the fourth straight section 16 is connected with a second endpoint of the third straight section 11.
The fifth straight line segment 15 is horizontally positioned on the opposite side of the second straight line segment 12, i.e. in the orientation of the male 2 on the insertion side (towards the inside of the female). A first end point (shown as the left end point) of the fifth straight line segment 15 connects to a second end point of the fourth straight line segment 16 and a second end point of the fifth straight line segment 15 connects to a second end point of the arc segment 14. The closed loop connection of the line segments is used for enclosing the special-shaped section outline of the sealing ring 1.
The first end point of the third straight line segment 11 and the second end point of the third straight line segment 11 simultaneously fall on the circumference of the imaginary circle 10.
Refer to fig. 1-2. In a preferred embodiment, the angle of inclination of the third straight line segment 11 may be 15 to 25 degrees. Namely, the angle e between the third straight line segment 11 and the vertical direction can be 15 to 25 degrees. The third straight line segment 11 is preferably inclined at an angle (included angle e) of 20 degrees.
Thus, an annular inclined slope is formed on the inner side of the gasket 1 corresponding to the third straight line segment 11. The male part 2 has a generally conical leading end 21 and the inclined cut on the inside of the seal ring 1 forms a leading engagement surface which forms a sliding engagement with the leading end 21 of the male part 2 at the same angle.
The first straight line segment 13 is tangent to the imaginary circle 10 at a first end point of the circular arc segment 14.
The fifth straight line segment 15 is tangent to the imaginary circle 10 at a second end point of the circular arc segment 14.
In a preferred embodiment, the arc angle c of the first arc segment on the imaginary circle 10 between the first end point of the third straight line segment 11 and the first end point of the arc segment 14 is greater than 90 degrees.
Further, the arc angle d of the second arc segment on the imaginary circle 10 between the second end point of the third straight-line segment 11 and the second end point of the arc segment 14 is smaller than 90 degrees.
Refer to fig. 2. When the male head 2 moves to be in contact with the sealing ring 1 of the female head in the inserting process, the sealing ring 1 begins to deform and climbs onto the male head 2. Frictional forces and positive pressure now provide the insertion force.
In the process, the positive pressure is maximized when the sealing ring 1 "climbs" to the transition 22 between the smooth curve of the contour of the leading end 21 of the male 2 and the perpendicular of the contour of the outer wall 23 of the male 2. The interaction force of the seal ring 1 and the male end 2 reaches the maximum at this time, namely the peak insertion force.
The design point of the utility model lies in that the male head 2 is in a relative horizontal sliding state when contacting the sealing ring 1 (namely contacting the inner side annular inclined tangent plane of the sealing ring 1 represented by the third straight line segment 11), so that the positive pressure is reduced, and the purpose of weakening the peak value of the insertion force can be achieved. Meanwhile, in order to ensure the compression amount, the sealing performance and the filling amount, the whole volume of the sealing ring 1 is required to be basically a fixed value (compared with an O-shaped sealing ring with the same specification). According to the principle, two volume compensation parts are designed, namely a first protrusion f which is formed by the first straight line segment 13 and the second straight line segment 12 and is positioned outside the circumference of the imaginary circle 10 is used as one volume compensation part, and a second protrusion g which is formed by the fourth straight line segment 16 and the fifth straight line segment 15 and is positioned outside the circumference of the imaginary circle 10 is used as the other volume compensation part.
It should be understood by those skilled in the art that the above embodiments are only used for illustrating the present invention, and not used as a limitation of the present invention, and that the changes and modifications to the above embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
