There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the structural schematic diagram after movable plate of the invention is opened；
Fig. 3 is the partial enlarged view in Fig. 2 of the invention；
Fig. 4 is the structural schematic diagram of flexible ring of the invention.
Specific embodiment
As shown in Figure 1, two protrusions are arranged in the mute door of this fire prevention, including door body 5, the front end face side protrusion of door body 5, two is convex
It is rotatablely installed a movable plate 4 between portion, a shaft hole is opened up on protrusion, 4 top and bottom of movable plate face the position of shaft hole
It is respectively provided with a shaft 1, is set with a torque spring in shaft 1, shaft 1 is rotatablely installed by torque spring in shaft hole, from
Movable plate and door body front end face compress when under right state, and the other end of movable plate 4 is open end, lock in door body 5 close to movable plate 4
Core side has been placed equidistant with more than one Buffer Unit 8 from top to bottom, is buffered by Buffer Unit 8 when closing door body
Mute, 5 front end face of door body is provided with a flexible ring 2 around the circle of door body edge side one, flexible ring 2 by movable plate 4 squeeze towards
The lateral surface protrusion of door body, projecting surface and door pocket inner wall are in sealing contact.
As shown in figure 3, Buffer Unit includes the more than one cushion chamber 85 being opened in door body, the side of cushion chamber 85
For outlet aperture 83, the outlet side of each outlet aperture 83 faces the stopper protrusion 31 of door pocket, the other side setting of cushion chamber 85
One limiting through hole, limiting through hole is interior to be packed into a flexible link 86, and one end of flexible link 86 is hinged in the shrinkage pool 88 of movable plate, another
A sealing piston 84 is welded and fixed in end, and suit is arranged more than one O-ring seal and (does not scheme in the outside wall surface of sealing piston 84
Show), buffering cavity wall is sealed by O-ring seal, the side of each cushion chamber 85 is respectively provided with an air intake structure.
Air intake structure includes the isocon 81 that 89, air inlet suction pipe 82 and one or more are responsible in an air inlet, air inlet supervisor 89
It is embedded in 5 inside of door body and is arranged perpendicular to horizontal plane, air inlet suction pipe 82 is embedded in door body 5 and sets perpendicular to air inlet supervisor 89
It sets, with the air intake passage of a both ends open inside air inlet suction pipe 82, it is logical that the air inlet in 89 with a difference is responsible in air inlet
The air intake passage in road, air inlet suction pipe 82 is communicated with the inlet channel of air inlet supervisor 89, and sucks outside by air inlet suction pipe 82
Air enters in air inlet supervisor 89, and one or more isocon 81 connect conducting with longitudinally disposed air inlet supervisor 89 respectively,
The inlet port of isocon is communicated with inlet channel, and the outlet port of isocon is communicated with one of cushion chamber 85, is shunted
The outlet port of pipe is partially protruded into cushion chamber 85.
Wherein, a Unidirectional air inlet valve 90, the inlet port and door body of air inlet suction pipe 82 are installed on air inlet suction pipe 82
Lateral surface is concordant, realizes quick air inlet by Unidirectional air inlet valve 90, can not achieve outlet, such movable plate is in quick open
Gas can be delivered by the air outside the sucking of air inlet suction pipe and by air inlet supervisor 89 and isocon 81 slow
Rush it is intracavitary, therefore open movable plate when dynamics it is bigger, the gas of sucking is more, at this time during opening by sucking gas
The mode of body reduces pulling force, increases door body service life.
And due between movable plate and door body by torque spring elastic connection, movable plate in its natural state when energy
Door body is enough compressed, when movable plate because after excessive pulling force is pulled open with respect to door body, as shown in Fig. 2, movable plate can be in torsion at this time
Restore deformation under the action of spring, sealing piston pushes in cushion chamber in recovery process so that the air in cushion chamber from compared with
Small outlet aperture discharge, at this time these air-flows gone out due to pressure it is larger, therefore can opposite door pocket stopper protrusion realization
Buffering, making it, cushion effect is bigger when closed, increases muting function.
Wherein, top and bottom open up a pin shaft hole in the shrinkage pool 88 of movable plate 4, and setting one is passed through among flexible link 86 and is turned
Dynamic pin 87, the two sides extension end of rotational pin 87 rotates respectively to be incorporated in pin shaft hole, by the setting of shrinkage pool 88, meets movable plate
The more flexible rotation of 4 one end.
Wherein, flexible link 86 is all made of a flexiplast bar, has not only been able to satisfy pico- deformation, but be able to achieve ejection and
Pulling action.
Wherein, lock body and door handle 6 are installed, movable plate integrally uses metal lagging system on the front end face of movable plate 4
At the position for facing installation lock body in door body 5 opens up an atrium (not shown), facilitates operation, passes through when opening the door
External atrium insertion lock core is unlocked, and normal operating is not influenced, and indoors toward when outward swinging door, i.e., using door opener
The pulling force of moment rotates movable plate and door body relative separation, realizes buffering and mute.
Wherein, as shown in figure 4, flexible ring 2 is whole in rectangle, it is arranged along door body outer, 2 inside hollow out of flexible ring is simultaneously
Filling gas, flexible ring 2 is whole to be made of flexible silica gel material, and flexible ring one side is bonded in door body, and movable plate is set
Compression after setting the loosening and shutdown when can satisfy enabling, the mute ability of sealing of the very good solution door body after closing.
The beneficial effects of the present invention are: one, movable plate of the invention uses metal lagging, there is extraordinary dicoration
And fire line；
Two, when opening the door, movable plate can pull open the present invention with respect to door-plate, so that opening movable plate with biggish power
When, it by Buffer Unit air-breathing, realizes buffering, is utilizing the exhaust of Buffer Unit to realize mute buffering at closing time, and then realize
Mute shutdown；
Three, the present invention is under the pressing force of movable plate, so that the flexible annular strain in door body squeezes out, so that soft after squeezing out
Property ring can be in sealing contact with door pocket inner wall, increase leakproofness, and then increase integral sealing effect and muting function.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
