" outward " etc. instruction orientation or position relationship be based on orientation shown in the drawings or position relationship, be only for
It is easy to describe this utility model and simplifying describe rather than instruction or the device of hint indication or element must
Must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that new to this practicality
The restriction of type.
As it is shown in figure 1, compression-expansion sealing-plug of the present utility model, its include inner cap 1, enclosing cover 2,
Inflating sealing body 3, support bar 4, sleeve 5, supporting member 7, two connecting rods 8 of 6, two handles,
Support bar 4 sequentially passes through sleeve 5, enclosing cover 2, inflating sealing body 3, the lower end of support bar 4 from top to bottom
Being connected to the end face of inner cap 1, the upper end of support bar 4 is connected to the middle part of supporting member 6, two handles 7
Being connected to the two ends of supporting member 6, one end of connecting rod 8 is connected to sleeve 5, connecting rod 8 another
One end is connected to handle 7, and handle 7 swung downward is used for so that sleeve 5 moves down.Pass through active force
In handle 7, handle 7 will be rotated down so that connecting rod 8 moves downward, thus band moving sleeve 5 to
Lower movement, moved down by sleeve 5 so that inflating sealing body 3 because of compression will to surrounding expand with
Reach sealing function, during use, only need to pull handle 7, can quickly realize sealing and sealing is the best,
Easy to use；Simple in construction simultaneously, easy to use, with low cost, safety is flexibly.Handle 7 is rotated
During to maximum angle, position-limiting action can be played so that compression-expansion sealing-plug keeps being in compression-expansion
State.
It is preferred that the material of inflating sealing body 3 is rubber or sponge, good airproof performance and cost-effective.Two
Individual handle 7 is all arranged with hands (not shown).Staff is the most preferably acted on
Power, in this compression-expansion sealing-plug, more convenient seals.
It is provided with the first rib 11 at the bottom edge of inner cap 1, makes Expansion sealing by the first rib 11
Inflating sealing body 3 will not be damaged between body 3 and inner cap 1 because of extruding, preferably protect inflating sealing body
3, keep elasticity and the sealing function of inflating sealing body 3, it is ensured that the stability of sealing.The top of enclosing cover 2
Face edge is provided with the second rib 21.By the second rib 21 make inflating sealing body 3 and enclosing cover 2 it
Between will not damage inflating sealing body 3 because of extruding, preferably protection inflating sealing body 3, keep expanding close
The elasticity of envelope body 3 and sealing function, it is ensured that the stability of sealing.
The end face of inner cap 1 is provided with swivel nut 12, and the lower end of support bar 4 is threadingly attached to swivel nut 12.
Make between inner cap 1, enclosing cover 2, inflating sealing body 3 and support bar 4 detachable, it is simple to maintenance and more
Change.Meanwhile, the upper end of support bar 4 also by being threadedly connected to supporting member 6, will realize support bar 4 with
Between supporting member 6 detachably, it is simple to keep in repair and change.So that inner cap in this compression-expansion sealing-plug
1, can enter between the structure of enclosing cover 2, inflating sealing body 3, support bar 4, sleeve 5, supporting member 6
Row dismounting so that be easy to maintenance and change, and can select corresponding according to the pipeline 9 of different tube diameters
Inner cap 1, enclosing cover 2 and inflating sealing body 3 seal.By inner cap 1, enclosing cover 2 with expand close
The shape of envelope body 3 all may be designed so that cylinder, cuboid or cylindroid so that compression-expansion sealing-plug
Can be to round tube, the pipeline 9 of rectangular tube and oval pipe seals, it is achieved can be by being combined into
The sealing-plug of plurality of specifications, seals meeting the pipeline 9 of different tube diameters, and versatility is the widest.
As depicted in figs. 1 and 2, this compression-expansion sealing-plug in use, first puts it into pipe to be sealed
In the mouth in road 9, firmly pull downwards handle 7 and make handle 7 be rotated down, promoted by connecting rod 8
