Opening uses as service ports, and is capped baffle plate in service ports to block, and such structure, easily causes at service ports and occurs
Situation about leaking out, is unfavorable for the air ambient of interior, and is less useful for the insulation of ventilation shaft and heat-insulated.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, security seal and can be beneficial to the logical of insulation
Wind pipeline repairs mouth mechanism.
To achieve these goals, the utility model provides following technical scheme：
A kind of ventilation shaft repairs mouth mechanism, including：
Frame, it is packed in the opening of ventilation shaft, and center line and opening center line are same straight line；
Door closure, it can be placed in the frame, for blocking the opening of ventilation shaft；
Heat insulation layer, it is fitted in the door closure and fills up the opening of ventilation shaft；
Backing pin, it is arranged on the edge of the frame, for carrying out barrier so that the door closure is maintained to the door closure
In the frame；
Sealing gasket, it is arranged between the door closure and frame and close to the opening of ventilation shaft.
Preferably, the frame is rectangle frame, the door closure is rectangle door closure.
Preferably, the heat insulation layer is glass fibre cotton.
Preferably, multiple otch being parallel to each other are offered on the glass fibre cotton.
Preferably, the backing pin is rotatably installed in the edge of the frame, and the center of pivot center and the frame
Line is parallel.
Preferably, the backing pin be two, the two backing pins relative to the frame center line symmetrical setting.
Ventilation shaft provided by the utility model repairs mouth mechanism, and it is arranged on the opening of ventilation shaft by frame
On, improve overall stability.Door closure, which is placed in frame, can be used for covering opening, and be pressed heat insulation layer in door closure,
Effectively insulation and heat-blocking action are served to ventilation shaft.Between door closure and frame close to opening sealing gasket then effectively
Sealing function is served, the appearance for the situation of leaking out can be avoided, it is ensured that IAQ.
Brief description of the drawings
, below will be to institute in embodiment in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
The accompanying drawing needed to use is briefly described, it should be apparent that, drawings in the following description are only described in the utility model
Some embodiments, for those of ordinary skill in the art, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the front view that the ventilation shaft that the utility model embodiment provides repairs mouth mechanism；
Fig. 2 is the upward view that the ventilation shaft that the utility model embodiment provides repairs mouth mechanism.
Description of reference numerals：
1st, frame；2nd, door closure；3rd, heat insulation layer；4th, backing pin；5th, sealing gasket；6th, the opening of ventilation shaft.
Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with accompanying drawing pair
The utility model is further detailed.
As depicted in figs. 1 and 2, a kind of ventilation shaft maintenance mouth mechanism, including frame 1, door closure 2, heat insulation layer 3, gear
Pin 4 and sealing gasket 5.Frame 1 is packed in the opening 6 of ventilation shaft, and center line and the center line of opening 6 are same straight line.
Door closure 2 can be placed in frame 1, for blocking the opening 6 of ventilation shaft.The opening 6 of usual ventilation shaft is all rectangle, therefore,
In the present embodiment, frame 1 is rectangle frame, and door closure 2 is also rectangle door closure.Heat insulation layer 3 is fitted in door closure 2 and filled up logical
The opening 6 of wind pipeline, it is preferable that heat insulation layer 3 is glass fibre cotton, and it has, and good insulating, heat resistance be strong, corrosion resistance
Well, the advantages of high mechanical strength.Further with improvement, multiple otch being parallel to each other are offered on glass fibre cotton, in order to
It extends.Sealing gasket 5 is arranged between door closure 2 and frame 1 and close to the opening of ventilation shaft.Backing pin 4 is arranged on the side of frame 1
At edge, for carrying out barrier so that the door closure 2 is maintained in frame 1 to door closure 2.In the present embodiment, backing pin 4 is rotatably installed in
The edge of frame 1, and the centerline parallel of pivot center and the frame 1, in this way, when needing to take out door closure 2, by backing pin 4
Door closure 2 is left, when needing to be capped door closure 2, first door closure 2 is placed in frame 1, then, being rotated further by backing pin 4 makes itself and door
Lid 2 against.Preferably, backing pin 4 be two, the two backing pins 4 relative to frame 1 center line symmetrical setting.Backing pin 4 removes
Ensure that door closure 2 is maintained in frame 1 using the mode that latch outside above-mentioned rotational structure, also may be selected, so as to can also make
Door closure 2 is obtained conveniently to take out and insert.
Above-mentioned ventilation shaft repairs mouth mechanism, and it is arranged on by frame 1 in the opening 6 of ventilation shaft, improves entirety
Stability.Door closure 2, which is placed in frame 1, can be used for covering opening 6, and be pressed heat insulation layer 3 in door closure 2, to ventilation duct
Road serves effectively insulation and heat-blocking action.Sealing gasket 5 between door closure 2 and frame 1 close to opening 6 then effectively acts as
Sealing function, the appearance for the situation of leaking out can be avoided, it is ensured that IAQ.
Some one exemplary embodiments of the present utility model are only described by way of explanation above, undoubtedly, for
One of ordinary skill in the art, can be with a variety of in the case of without departing from spirit and scope of the present utility model
Mode is modified to described embodiment.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as
Limitation to the utility model claims protection domain.
