The utility model is further arranged to: the conflict block of truncated cone-shaped is coaxially provided in the taper hole, the conflict block
It is bonded inside side wall and taper hole.
By using above-mentioned technical proposal, when the air pressure in hole increases, it will push conflict block and slided to blind hole direction, from
And conflict block contacts at the side wall of taper hole, and then increases the pressure between the side wall of stopper rod and the inner wall in hole, so that progress increases
The leakproofness of rubber seal plug.
The utility model is further arranged to: the small end face of the conflict block has been fixedly and coaxially connected mandril, the mandril
Side wall be bonded with the side wall of blind hole.
Mandril sliding is driven by using above-mentioned technical proposal, when conflict block is mobile, so that mandril squeezes the sky in blind hole
Between, compress the air in the space of blind via bottom, thus side wall and need to be mounted hole of the stopper rod close to the one end on head
Inner wall fit closely.
The utility model is further arranged to: the mandril includes connecting rod and piston block, and described connecting rod one end is coaxial
It is fixedly connected on the small end face of conflict block, the piston block is fixedly and coaxially connected one end in connecting rod far from conflict block, described
Piston block and blind hole are interference fitted, and the diameter of the connecting rod is less than diameter of blind hole.
By using above-mentioned technical proposal, when conflict block is mobile to the direction close to head, the internal diameter of big-diameter blind hole can be supportted, from
And reduce the sealing performance that blind hole internal diameter becomes larger and cause piston block Yu blind hole inner wall.
The utility model is further arranged to: the piston block side wall coaxially offers multiple annular grooves.
By using above-mentioned technical proposal, the inside of blind hole utilizes annular groove enhancing to piston in annular groove
Leakproofness between block side wall and blind hole inner wall.
The utility model is further arranged to: the second arc angling is equipped between the stopper rod end face and its side wall.
By using above-mentioned technical proposal, facilitate stopper rod plug as in need hole to be mounted.
In conclusion the utility model has the following beneficial effects:
First, the air pressure in blind hole increases and applies pressure, Jin Erzeng to blind hole inner wall when the air pressure in hole increases
The pressure jumped a queue between the side wall of bar and the inner wall in hole, so that progress increases the leakproofness of rubber seal plug；
Second, will push conflict block when the air pressure in hole increases and slided to blind hole direction, so that conflict block contacts at cone
The side wall in hole, and then increase the pressure between the side wall of stopper rod and the inner wall in hole, so that progress increases the close of rubber seal plug
Feng Xing；
Third, mandril sliding is driven to make the sky of blind via bottom so that mandril squeezes the space in blind hole when conflict block is mobile
Interior air is compressed, so that side wall of the stopper rod close to the one end on head is fitted closely with the inner wall in hole to be mounted is needed.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment 1: a kind of high leakproofness rubber tube external seal plug, as depicted in figs. 1 and 2, including stopper rod 1 and head 2.Head
Portion 2 is the cylinder that diameter is greater than its axial length, and the coaxial arrangement of 1 one end of stopper rod is in 2 one end of head and the two is by rubber one
Body injection molded.When installation, stopper rod 1, which is inserted in, to be needed closely to paste in hole to be mounted using the side wall of stopper rod 1 and the inner wall in hole
It closes, so that hole be sealed.Stopper rod 1 and 2 junction of head are equipped with the first arc angling 11, are reduced using the first arc angling 11 and are filled in
The stress of bar 1 and 2 junction of head, increases stopper rod 1 and 2 connection structure intensity of head, and reduction stopper rod 1 occurs and tears with head 2
A possibility that splitting.
As shown in Fig. 2, the one end of stopper rod 1 far from head 2 coaxially offers blind hole 3, blind hole 3 extends to stopper rod 1 close to head
The one end in portion 2.When the air pressure in the hole for needing to seal increases, the air pressure in blind hole 3, which increases and applies to 3 inner wall of blind hole, is pressed
Power, and then increase the pressure between the side wall of stopper rod 1 and the inner wall in hole, so that progress increases the leakproofness of rubber seal plug.
For convenience the plug of stopper rod 1 is equipped with the second arc angling 12 in the hole for needing to seal between 1 end face of stopper rod and its side wall, filled in
The one end of bar 1 far from head 2 coaxially offers the taper hole 31 being connected to blind hole 3, and the big end of taper hole 31 faces away from the side on head 2
To.When stopper rod 1 is filled in the hole for needing to seal, the one end of stopper rod 1 far from head 2 is squeezed, to make stopper rod 1 far from head 2
The diameter of one end reduce, then play guiding role using the second arc angling 12, facilitate by by the plug of stopper rod 1 in needing to seal
Hole in.Also sealing-plug sealed pipe fittings be can use, using needing the pipe fitting that seals to be placed through in blind hole 3, make 3 inner wall of blind hole with
The side wall for the pipe fitting for needing to seal fits closely.
The implementation principle of the present embodiment are as follows: when installation, stopper rod 1, which is inserted in, to be needed to utilize the side of stopper rod 1 in hole to be mounted
Wall and the inner wall in hole fit closely, so that hole be sealed.When the air pressure in hole increases, the air pressure in blind hole 3 increases and right
3 inner wall of blind hole applies pressure, and then increases the pressure between the side wall of stopper rod 1 and the inner wall in hole, so that progress increases rubber
The leakproofness of sealing-plug.
Embodiment 2: a kind of high leakproofness rubber tube external seal plug, difference from Example 1 are, as shown in figure 3, also
Including conflict block 4 and the mandril being fixedly and coaxially connected with conflict block 45.Conflict block 4 is in truncated cone-shaped and is coaxially placed in taper hole 31
It is interior, one end of the small end of conflict block 4 headward 2 and its side wall is bonded with the side wall of taper hole 31.
As shown in figure 3, mandril 5 includes connecting rod 51 and piston block 52,51 one end of connecting rod is fixedly and coaxially connected in conflict
The small end face of block 4, piston block 52 is rounded and is fixedly and coaxially connected in the one end of connecting rod 51 far from conflict block 4, piston block
52 are interference fitted with blind hole 3, and the diameter of connecting rod 51 is less than the diameter of blind hole 3.When the air pressure in the hole for needing to seal increases,
Conflict block 4 is pushed to slide to 3 direction of blind hole, drive lower slider of the piston block 52 in conflict block 4.Conflict block 4 is slided to head 2
When, conflict block 4 contacts at the side wall of taper hole 31, and then increases the pressure between the side wall of stopper rod 1 and the inner wall in hole, thus progress
Increase the leakproofness of rubber seal plug.When piston block 52 is slided to head 2, piston block 52 squeezes the space in blind hole 3, makes blind
Air in the space of 3 bottom of hole is compressed, so that stopper rod 1 is in the side wall and need hole to be mounted of the one end on head 2
Wall fits closely.
As shown in Figure 3 and Figure 4, in order to increase the leakproofness between 3 inner wall of 52 side wall of piston block and blind hole, 52 side of piston block
Wall coaxially offers multiple annular grooves 521, thus the inside of blind hole 3 in the annular groove 521, make 52 side wall of piston block with
3 inner wall of blind hole is bonded even closer.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
