Description
Technical field
The utility model relates to a kind of doors, more specifically, it relates to a kind of mute steel-made fire-retardant door.
Background technique
The upsurge of urbanization becomes people is made persistently to pour in city, to meet the needs of people are to house, the room of big and medium-sized cities
Real estate is that exception is hot, and along with the rapid development of real estate, the demand of steel door is high.
Steel door intensity is high, moisture resistance, corrosion-resistant, brings the sense of security for room, occupies in modern furniture finishing important
Status.Steel door is commonly provided with the doorframe of steel, hits in the moment door body and doorframe of shutdown and generates biggish strike note, especially
It is when closing the door firmly larger, this relatively disturbs residents.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of mute steel-made fire-retardant door,
Its noise very little, muting function when closing the door are good.
To achieve the above object, the utility model provides following technical solution：
A kind of mute steel-made fire-retardant door, including door body and handle, the positive edge of the door body and door frame contact
The flexible buffer bar of setting, the buffer bar are adhesively fixed with door body in annular region, and the buffer bar includes first hollow
Item, the front of hollow bar is the arc convex for protruding from door body surface in described first, is provided with second in hollow bar in described first
Middle hollow bar, the front of hollow bar is also the arc convex for protruding from door body surface in described second, the front of hollow bar in described second
With first between hollow bar there are gap, the curvature of the front of hollow bar is greater than the curved of the front of hollow bar in first in described second
Curvature.
Preferably：Air hole is offered in hollow bar in hollow bar and second in described first.
Preferably：The position of air hole in described first in hollow bar and second in hollow bar is in correspondence with each other.
Preferably：Hollow bar is internally provided with hollow bar in the third of sealing in described second, and the third is hollow
The inside of item is filled with air, and the front of hollow bar is also the arc convex for protruding from door body surface in the third, in the third
Also there are gaps between hollow bar in the front of hollow bar and second.
Preferably：The buffer bar is rubber strip.
Preferably：Perlite fireproof plate is also embedded in the door body.
Compared with prior art, the utility model has the advantages that：The steel door, when being turned off, in door body and doorframe
Before contact, buffer bar and door frame contact before this, after buffer bar is by the extruding of doorframe, hollow bar compressive deformation in first, thus
Play the role of deceleration door body movement velocity, after hollow bar is compressed into the hollow bar contact in second in first, hollow bar in second
Also start to deform, bigger elastic force is generated after hollow bar is superimposed with the elastic force of hollow bar in first in first to door body, thus more effectively
Ground be door body slow down, in this way, when door body finally with door frame contact after, very little has been weakened to obtain to the impact force of doorframe,
To make the moment sound very little closed the door, reach ideal muting function.
Detailed description of the invention

Specific embodiment
Referring to Fig.1, a kind of mute steel-made fire-retardant door, including door body 1 and handle 2, at the positive edge and door of door body 1
The flexible buffer bar 3 of setting, buffer bar 3 are adhesively fixed with door body 1 in the annular region of frame contact.
Referring to Fig. 2, buffer bar 3 includes hollow bar 301 in first, the front of hollow bar 301 in first（I.e. its towards door body 1 before
The one side of side）For the arc convex for protruding from 1 surface of door body, hollow bar 302 in second are provided in hollow bar 301 in first,
The front of hollow bar 302 is also the arc convex for protruding from 1 surface of door body in two, the front of hollow bar 302 and first hollow in second
There are gap between item 301, the curvature of the front of hollow bar 302 is greater than the curvature of the front of hollow bar 301 in first in second.
The steel door, when being turned off, before door body 1 and door frame contact, buffer bar 3 and door frame contact, were buffered before this
After item 3 is by the extruding of doorframe, 301 compressive deformation of hollow bar in first, thus play the role of 1 movement velocity of deceleration door body,
After hollow bar 301 is compressed into the contact of hollow bar 302 in second in first, hollow bar 302 also starts to deform in second, and first is hollow
Item 301 generates bigger elastic force to door body 1 after being superimposed with the elastic force of hollow bar 301 in first, to more effectively subtract for door body 1
Speed, in this way, when door body 1 finally with door frame contact after, very little has been weakened to obtain to the impact force of doorframe, to make to close the door
Moment sound very little, reach ideal muting function.
In the present embodiment, air hole 4 is offered in hollow bar 302 in hollow bar 301 and second in first, air hole 4 makes
Air in first in hollow bar 301 and second inside and outside hollow bar 302 can circulate, make in first hollow bar in hollow bar 301 and second
302 deformation is not influenced by air pressure, to guarantee that hollow bar 302 can generate maximum shape in hollow bar 301 and second in first
Become, buffer bar 3 is enabled to reach best buffering effect.
Here, the position of the air hole 4 in first in hollow bar 301 and second in hollow bar 302 is in correspondence with each other, so may be used
To guarantee that air-flow is unobstructed.
On the basis of above structure, the hollow bar 303 in the third for being internally provided with sealing of hollow bar 302 also in second,
The front of hollow bar 303 is also the arc convex for protruding from 1 surface of door body in third, and the front of hollow bar 303 and second in third
Also there are gaps between middle hollow bar 302.The inside of hollow bar 303 is filled with air in third.The addition of hollow bar 303 is further in third
The cushion performance for improving buffer bar 3 keeps noise reduction effect more preferable.
In the present embodiment, buffer bar 3 is using rubber material.
In addition, being also embedded with perlite fireproof plate in door body 1（It is not shown）, so that the steel door has preferable fire line
Energy.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
