End is flexibly connected by connector with bolt, the other end and supporting surface against.
Preferably, the connector includes riffled tube and activity knot；One end of the riffled tube is spirally connected with bolt, separately
One end and activity knot weld；Activity knot is connect with support rod, and can be around support rod radial rotating.
Preferably, " c-type " activity knot is become in the activity.
Preferably, sealant is coated in the bolt bottom end of rubber block front end face.
Preferably, rubber pad is provided between support rod and supporting surface.
It is a further object to provide a kind of application methods of locking blocking of rigid box air seal test, including with
Lower step:
(1) it is combined through series connection rubber block, sheet metal, bolt to form sub-assembly, tightens nut, sheet metal is made to press rubber block；
(2) by the sub-assembly indentation rigid box venthole in (1), screwed pipe is spirally connected bolt, and bending " c-type " activity knot is adjusted
Whole good support rod is at a distance from supporting surface；
(3) sub-assembly in (1) is compacted, prevents rigid box gas permeation, adjust rubber pad at a distance from supporting surface；
(4) pressing " c-type " activity knot makes " c-type " activity knot be in same straight line with support rod；
(5) start to carry out rigid box air seal test, tapping " c-type " activity knot, is extracted after unclamping support rod after the completion of test
(1) sub-assembly in.
Compared with prior art, the present invention has the advantage that
1, can Reusability, deform it is smaller；
2, blocking installation, dismantle it is quick and convenient；
3, plugging effect is good, structure is simple, easy to operate.

Specific embodiment
2-3 is further described the present invention with reference to the accompanying drawing: as Figure 2-3, a kind of rigid box air seal test
Locking blocking, including rubber block 4, metal plate 3, bolt 2, nut 6, riffled tube 7, support rod 9 and c-type activity 11.
Respectively there are one piece of horminess metal plate 3, metal plate 5, the spiral shell of rubber block front end face in the front end face and rear end face of rubber block 4
Bolt bottom end coating can vulcanized sealant 1, prevent gas permeation；By bolt 2 successively by metal plate 3, rubber block 4 and metal plate 5
Concatenation, and tightens fixation by tightening nut 6, is compacted rubber block 4 by horminess metal plate 3, metal plate 5, prevent rubber stopper 4 by
Rigid box, which squeezes, occurs excessive deformation, plays good anti-deformation and plugging effect.
In order to support rubber block 4 not loosen during interior high-potting, a fast demountable is designed convenient for movable
Support rod 9,9 tail portion of support rod are equipped with one piece of rubber pad 10, and rubber pad 10 has certain decrement, bar 9 easy to support and branch
There is certain adjustable ball space between support face 12.
Support rod 9 is connect with rubber block 4 by riffled tube 7, and riffled tube 7 and the end of bolt 2 are spirally connected, and is convenient for rubber
The connection and disassembly of block 4 and support rod 9.
Support rod 9 is connect with riffled tube 7 by " c-type " movable knot 11, installation when convenient for rigid box air seal test
With disassembly；Two free ends of " c-type " activity knot 11 are fixed by straight pin 8 with support rod 9, while under the effect of external force
It can be around the radial rotating of support rod 9.
The rubber blocking indentation rigidity that rubber block 4, metal plate 3, metal plate 5, bolt 2, nut 6 and sealant 1 are formed
In the venthole of cabinet, the more tight puckery of rubber blocking compacting, nut 6 is tightened, presses rubber block 4 by hard metal piece 3,5
It is real；Screwed pipe 7 connects bolt 2；Rubber pad 10 is bonded supporting surface 12, support rod 9 is placed on supporting surface 12, and pressing " c-type " is living
Dynamic knot 11 keeps support rod 9 not occurred by certain pressure curved so that " c-type " activity knot is on same straight line with strut 9
It is bent.
Application method:
1) rubber is blocked in indentation rigid box venthole 13, is spirally connected bolt 2 by screwed pipe 7, and be bent " c-type " activity
Knot 11 adjusts strut 9 at a distance from ground 12 convenient for the progress of test；
2) nut 6 is tightened, forces sheet metal 3, sheet metal 5 to press rubber block 4, when guaranteeing that rubber block is squeezed by cabinet venthole
Without excessive deformation, good plugging effect is kept；
3) rubber is filled in rigid box venthole, being compacted rubber block prevents cabinet gas permeation, adjusts rubber
Pad 10 is at a distance from supporting surface 12；
4) adjustment support rod 9 is at a distance from supporting surface 12, the movable knot 11 of pressing " c-type ", so that support rod 9 is by certain pressure
It does not bend, " c-type " movable knot 11 is kept to be in same straight line with support rod 9；
5) start to carry out rigid box air seal test, the movable knot 11 of tapping " c-type ", is pulled out after unclamping support rod after the completion of test
Rubber blocks out.
Above-described embodiment is only that of the invention is described in further detail, and is not construed as limiting the invention.Support rod may be used also
To be needed to select various length support bars according to experiment.Any modification for all within the spirits and principles of the present invention, being made, etc.
With replacement, improvement etc., it is included in protection scope of the present invention.
