Just for the sake of helping comprehensive understanding embodiments herein.It therefore, it will be apparent to those skilled in the art that can be to retouching here
The embodiment stated makes various changes and modifications without departing from the scope and spirit of the present application.In addition, for clarity and brevity, saving
The description to known function and construction is omited.
Present applicant proposes a kind of pipe sealing structures, comprising: mounting rack, pushing mechanism, clamping sleeve, gasket, adjustment handle
Hand；The pushing mechanism is mounted on mounting rack, adjusts the adjusting rod of the pushing mechanism, and adjusting rod rotation drives push rod to push away
The rubber ring of the fixed compress gasket of dynamic pressure.Clamping sleeve squeezes the rubber ring of the gasket, so that connection clamping sleeve and pipe to be sealed
Between junction reach sealing；Since the rubber ring of gasket deforms under the extruding of clamping sleeve, sealing is formed.Due to
The material is soft for rubber ring, will not damage to the tube end of junction.In addition, the application is sealed by adjusting rod,
It is very easy in operation.
In addition, the pipe end for the automobile pipeline that the pipe sealing structure that the application proposes is applied to automobile pipeline is sealed.
Referring to figs. 1 to Fig. 3, the pipe sealing structure includes: mounting rack 1, pushing mechanism 2, clamping sleeve 3, gasket 4, adjusts
Whole handle 5.
The gasket 4 be sleeved on pipe 0 to be sealed on the outer wall of close end；The gasket 4 is including rubber ring 41 and admittedly
Determine ring 42, the rubber ring 41 is located between the outer wall and fixed ring 42 of pipe 0 to be sealed.
It should be noted that the gasket 4 is made of rubber ring 41 and fixed ring 42, the rubber ring 41 is located inside,
Fixed ring 42 is located at outside.Rubber ring 41 is wrapped on the outer wall of pipe 0 to be sealed, and can be formed and be sealed in contact position.
Fixed ring 42 can prevent the outside displacement in extrusion of rubber ring 41, enable junction by rubber
Ring 41 is sufficient filling with, and then ensure that the leakproofness of rubber ring 41.
In addition, the fixed ring 42 in gasket 4 can also be used in the shape for keeping rubber ring 41, so that gasket 4 is easily installed.
With continued reference to Fig. 5, in the embodiment of the present application, peripheral direction has one to the rubber ring 41 of the gasket 4 on the outside
Circumferential groove 411；The fixed ring 42 has a circumferential protrusion 421 in inside peripheral direction, and the circumferential direction protrusion 421 is solid
Due in the circumferential groove 411.
By the cooperation of the circumferential protrusion 421 and circumferential groove 411, so that rubber ring 41 is more easily kept fixed shape
Shape.
In addition, the cooperation by the circumferential protrusion 421 and circumferential groove 411 also to be squeezed in rubber ring 41
When generated deformation it is more regular and uniform, be conducive to seal.
With continued reference to Fig. 2, for an end cap of the adjustment handle 5 on pipe 0 to be sealed, the other end is adjustable side 51；It is described
One end of clamping sleeve 3 is socketed on the outer wall of 0 end of pipe to be sealed, and resists the gasket 4；The clamping sleeve 3 has in inside
There is a partition portion 31；The gasket 4 is between the adjustment handle 5 and clamping sleeve 3；Clamping sleeve 3 is for squeezing the gasket 4
Rubber ring 41 so that the junction between clamping sleeve 3 and pipe to be sealed 0 reaches sealing.
The adjustment handle 5 can be used for adjusting the position of pipe 0 to be sealed, more convenient in operation.
With continued reference to Fig. 4, in the embodiment of the present application, the adjustment handle 5 has a through-hole 51, and passes through the through-hole
51 sets on pipe 0 to be sealed；The inner wall of the through-hole 51 is circumferentially evenly distributed with strip bulge 52.
It should be noted that the damage that can avoid the tube wall of pipe 0 to be sealed by the way that strip bulge 52 is arranged on through-hole 51.
When 3 stress of clamping sleeve squeezes the rubber ring 41 of the gasket 4, deformation occurs wraps compression for the rubber ring 41
The junction of set 3 and pipe 0 to be sealed, so that being sealed in the junction.Further, since clamping sleeve 3 has a partition portion in inside
31, it is sealing inside clamping sleeve 3.So need to be only sealed in clamping sleeve 3 and the junction of pipe 0 to be sealed, so that it may seal
The firmly end of pipe 0 to be sealed.
It should be noted that causing to damage so seal pipe 0 will not be treated in sealing since the material is soft for rubber ring 41
Wound.
The pushing mechanism 2 includes: mounting base 21, push rod 22, connecting rod 23, adjusting rod 24, and the mounting base 21 is fixed
On the mounting rack 1；One end of the adjusting rod 24 and the mounting base 21 are rotatablely connected；The connecting rod 23 respectively with push away
On one end of bar 22, adjusting rod 24 one at be rotatablely connected；There is a pilot hole 211, the push rod 22 in the mounting base 21
It is slidably mounted in the pilot hole 211；The adjusting rod 24 rotates, and push rod 22 is driven to push the rubber of 3 compress gasket 4 of clamping sleeve
Rubber ring 41.
It should be noted that the position of junction of the connecting rod 23 on adjusting rod 24, it can determines according to actual conditions, only
Operation need to be met to need, even if adjusting rod 24 rotates, drive push rod 22 to push 3 compress gasket of clamping sleeve by connecting rod 23
4 rubber ring 41.
When adjusting rod 24 rotates, push rod 22 pushes clamping sleeve 3 to move to compress gasket 4, and pushes 3 clamping pad of clamping sleeve
The rubber ring 41 of piece 4, and then the rubber ring 41 of the gasket 4 is squeezed, reach the junction between clamping sleeve 3 and pipe to be sealed 0
To sealing.
In the embodiment of the present application, the mounting rack 1 has fixing groove 11, and the pipe 0 to be sealed is placed in the fixation
In slot 11.
Fixing groove 11 can be used for the placement of pipe 0 to be sealed, simplify operation, avoid the position for treating seal pipe 0 from carrying out more
Secondary adjusting.
In the embodiment of the present application, the pipe to be sealed 0 has a circumferential protrusion 01 in outer wall；The circumferential direction protrusion
01 is located between gasket 4 and adjustment handle 5.
It should be noted that the end of pipe 0 to be sealed there can be various shapes, but the reality of technical scheme is not influenced
It applies.
In the embodiment of the present application, the mounting base 21, which is connected through a screw thread, is fixed on the mounting rack 1.
With continued reference to Fig. 3, in the embodiment of the present application, the mounting rack 1 is equipped with two rows of spiral shells in 22 glide direction of push rod
Line mounting hole 12；The mounting base 21 of the pushing mechanism 2 is mounted on the mounting rack 1 by the threaded mounting hole 12
On.
