This sealing means sealing effect is poor.
Summary of the invention
The purpose of the present invention is to propose to a kind of pipe sealing structures, overcome the above-mentioned deficiency of the prior art, leakproofness
Can be strong, it is able to maintain prolonged sealing effect, market use demand is met, is conducive to product promotion.
In order to reach above-mentioned purpose of design, The technical solution adopted by the invention is as follows:
A kind of pipe sealing structure, including the first pipeline, the second pipeline, sealing element, first pipeline is interior to be equipped with pore,
First pipeline one end is equipped with flange, and described second pipeline end opposite with flange is equipped with flange, is equipped with pore, institute in the second pipeline
It states and is equipped with sealing element between the first pipeline, the second pipeline, sealing element center is equipped with through-hole, the through-hole wall middle part of the sealing element
Equipped with concave ring, the sealing element both ends opposite with concave ring two sidewalls are respectively equipped with from the outwardly extending bulge loop in through-hole edge, sealing
It is equipped with concave ring respectively at two close end on the outer wall of part, the sealing element both ends opposite with concave ring are respectively equipped with from sealing element outer wall
The outwardly extending bulge loop in edge.
The outer wall of the bulge loop is inclined surface structure.
The two sidewalls of the concave ring are incline structure, the tilt angle of the outer wall of the sidewall slope angle and bulge loop of concave ring
It is identical.
The bottom of the concave ring of the through-hole wall is arcuate structure；The bottom of the concave ring of the outer wall of the sealing element is arc
Structure.
The bulge loop is extended in pore by the way of interference fit.
The diameter of the through-hole and the diameter of pore are identical.
The sealing element is equipped with fixation hole close to edge, and fixation hole is opposite with the hole that the flange of the first pipeline is equipped with to be set
It sets, and the hole being equipped with the flange of second pipeline one end is oppositely arranged.
The beneficial effect of pipe sealing structure of the present invention is: sealing performance is strong, is able to maintain prolonged sealing
Effect meets market use demand, is conducive to product promotion.
Detailed description of the invention
Fig. 1 is the schematic diagram of pipe sealing structure of the present invention；
Fig. 2 is the cross-sectional view of the sealing element of pipe sealing structure of the present invention；
Fig. 3 is the side view of the sealing element of pipe sealing structure of the present invention.
Specific embodiment
Preferred embodiment of the invention is described in further detail below.
As shown in Figure 1-3, in embodiment of the present invention, the pipe sealing structure, including the first pipeline 1, the second pipeline
4, sealing element 7, first pipeline 1 is interior to be equipped with pore 2, and 1 one end of the first pipeline is equipped with flange 3, with flange 3 relatively described second
The end of pipeline 4 is equipped with flange 6, is equipped with pore 5 in the second pipeline 4, sealing element is equipped between first pipeline 1, the second pipeline 4
7,7 center of sealing element is equipped with through-hole 8, concave ring 11 is equipped in the middle part of 8 inner wall of through-hole of the sealing element 7, with 11 two sidewalls phase of concave ring
7 both ends of sealing element are respectively equipped with from the outwardly extending bulge loop 9 in 8 edge of through-hole, the outer wall of sealing element 7 at two close end
It is respectively equipped with concave ring 12, is respectively equipped with relatively described 7 both ends of sealing element of concave ring 12 outwardly extending from 7 outer wall edge of sealing element
Bulge loop 10 deforms in use, the flange of 7 two sides of sealing element squeezes the concave ring 12 that bulge loop 10 is, enhances leakproofness, seal simultaneously
The flange of 7 two sides of part squeezes bulge loop 9, so that concave ring 11 deforms, enhances leakproofness.
The bulge loop 9, bulge loop 10 outer wall be inclined surface structure.
11 two sidewalls of concave ring are incline structure, the inclination angle of the outer wall of the sidewall slope angle and bulge loop 9 of concave ring 11
It spends identical.
The two sidewalls of the concave ring 12 are incline structure, the sidewall slope angle of concave ring 12 and inclining for the outer wall of bulge loop 10
Rake angle is identical.
The bottom of the concave ring 11 of 8 inner wall of through-hole is arcuate structure, prevents from tearing；The outer wall of the sealing element 7 it is recessed
The bottom of ring 12 is arcuate structure, prevents from tearing.
The bulge loop 9 is extended in pore by the way of interference fit.
The diameter of the through-hole 8 is identical as the diameter of pore.
The sealing element 7 is equipped with fixation hole 7, the hole that the flange 3 of fixation hole 7 and the first pipeline 1 is equipped with close to edge
It is oppositely arranged, and the hole being equipped with the flange 6 of 4 one end of the second pipeline is oppositely arranged.
