Description
Technical field
The utility model is related to sealing device technical field more particularly to a kind of biology laboratory tube sealing devices through walls.
Background technology
Involved virus and bacterium all have highly pathogenic, high lethal, and their propagation in biology laboratory
Medium is mostly air, this just needs laboratory itself to have good leakproofness；For example, the electric wire pipeline of laboratory internal
It is required for the ground across laboratory, wall, furred ceiling etc. with upper and lower conduit road, these are all inevitably related to wall pipe
Sealing problem.The sealing dress for injecting fluid sealant into the gap that wall pipe generates or buying import is taken in present engineering mostly
It sets and is sealed；But stringent leakproofness can not be ensured by carrying out leak stopping using fluid sealant, and fluid sealant is after using for a longer period
The aging phenomenon of appearance can also form air leakage point；And buy imported product then and have that cost is excessively high, problem of shipping period length, and
External product also cannot be satisfied the construction specification in domestic laboratory sometimes.
Invention content
The utility model is exactly directed to the above technical problem, provides a kind of biology laboratory tube sealing device through walls.
The utility model to achieve the above object, using following technical scheme：A kind of biology laboratory seal of tube dress through walls
It sets, includes the pre-buried hold-down frame for the bucking ladder structure being embedded in advance in wall, be equipped in pre-buried hold-down frame and use fire-retardant rubber
Sealing filling core made of glue, the upper end of pre-buried hold-down frame are bolted the trigger squeeze of compression seal filling core
Structure, and it is equipped with through-hole accordingly on pre-buried hold-down frame, sealing filling core and press plate mechanism, it is equipped with wall pipe in through-hole, is worn
It is cased with casing on the outside of wall coil, sealing filled layer and cushion rubber layer are equipped between casing and wall pipe, sealing filled layer is close
Casing side is arranged, and cushion rubber layer is arranged close to wall pipe side, and the outside of casing is equipped with waterproof layer.
Tung oil gypsum putty is filled in the sealing filled layer.
The thickness of the sealing filled layer and cushion rubber layer is all 4-6cm.
The waterproof layer is polyurethane foam glue.
Compared with prior art, the utility model has the beneficial effects that：The utility model setting bucking ladder structure it is pre-
Pile things on tight frame can also be squeezed, to embrace wall pipe when sealing filling core is deformed by transverse pressure by longitudinal direction
Tightening seal, sealing effect are preferable；And the setting of cushion rubber layer can effectively alleviate the friction and collision that wall pipe is subject to,
Play the role of protecting wall pipe, extends the service life of wall pipe.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1, pre-buried hold-down frame；2, sealing filling core；3, press plate mechanism；4, wall pipe；5, casing；6, it seals
Filled layer；7, cushion rubber layer；8, waterproof layer；9, bolt.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figure 1, a kind of biology laboratory tube sealing device through walls, including the bucking ladder structure that is embedded in advance in wall
Pre-buried hold-down frame 1, be equipped in pre-buried hold-down frame 1 using sealing filling core 2, pre-buried compression frame made of flame retardant rubber
The upper end of frame 1 is fixed with the press plate mechanism 3 that compression seal fills core 2, and pre-buried hold-down frame 1, sealing filling by bolt 9
Through-hole is equipped in core 2 and press plate mechanism 3 accordingly, wall pipe 4 is equipped in through-hole, the outside of wall pipe 4 is cased with casing 5, covers
Sealing filled layer 6 and cushion rubber layer 7 are equipped between pipe 5 and wall pipe 4, sealing filled layer 6 is arranged close to 5 side of casing, rubber
Glue buffer layer 7 is arranged close to 4 side of wall pipe, and the outside of casing 5 is equipped with waterproof layer 8.
Tung oil gypsum putty is filled in the sealing filled layer 6.
The thickness of the sealing filled layer 6 and cushion rubber layer 7 is all 4-6cm.
The waterproof layer 8 is polyurethane foam glue.
When the utility model is constructed, the pre-buried hold-down frame 1 of bucking ladder structure is embedded in wall in advance, sealing is filled
Core 2 is inserted in pre-buried hold-down frame 1, and wall pipe 4 is inserted into pre-buried hold-down frame 1, sealing filling core 2 and press plate mechanism 3
In the through-hole of upper setting, then press plate mechanism 3 connect with pre-buried hold-down frame 1 by bolt 9, then continuous fastening bolt 9 makes
Press plate mechanism 3 compresses sealing filling core 2；Since pre-buried hold-down frame 1 is bucking ladder structure, so filling core 2 in sealing
It when being deformed by transverse pressure, can also be squeezed by longitudinal direction, be sealed to hold wall pipe 4 tightly, sealing effect is preferable；And
The setting of cushion rubber layer 7 can effectively alleviate the friction and collision that wall pipe 4 is subject to, and play the role of protecting wall pipe 4；
In addition, the setting of 5 outside waterproof layer 8 of casing, can effectively avoid wall pipe 4 from corroding because contacting rainwater, extend wall pipe 4
Service life.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the various improvement of the methodology and technical solution progress of the utility model are used, or without
Improvement directly applies to other occasions, both is within the protection scope of the present invention.
