Specific embodiment
In order to make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment and join
According to attached drawing, the present invention is described in more detail.It should be understood that these descriptions are merely illustrative, and it is not intended to limit this hair
Bright range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid this is unnecessarily obscured
The concept of invention.
As shown in Figs 1-4, a kind of fire prevention hinders taste door, including doorframe 1, door leaf 2 and fire prevention Expandable strip, in doorframe 1 and door leaf 2
When closure, doorframe 1 is enclosed in 2 surrounding of door leaf in concave shape, as shown in Figure 2;First fire prevention Expandable strip 3 setting with 2 side of door leaf
On opposite 1 inner concave of doorframe in side, corresponding position has the groove 5 for placing the first fire prevention Expandable strip 3, the first fire prevention on doorframe 1
Expandable strip 3 is placed in groove 5, keeps certain distance with door leaf 2, will not be interfered with door leaf 2 when so that closing the door, opening the door.
It is equipped with fixed plate 6 in 2 outer ledge of door leaf, is provided with the second fire prevention Expandable strip 4 in fixed plate 6, the second fire prevention Expandable strip 4 is from outer
Gap and covering 1 marginal portion of doorframe when side covering doorframe 1 and door leaf 2 are closed between the two, fixed plate 6 is tabs shape
Shape places the outer end of the second fire prevention Expandable strip 4 far from 2 outside certain distance of door leaf, so that the when doorframe 1 and door leaf 2 are closed
Two fire prevention Expandable strips 4 cover 1 marginal portions of doorframe, and not to 1 marginal portion of doorframe apply pressure, or not with 1 edge of doorframe
Part contacts.
It further include sealing unit, sealing unit is made of stiffening plate 7, sealing element fixed part 8 and sealing element 9, and stiffening plate 7 is set
It is placed in inside door leaf 2 or doorframe 1, sealing element fixed part 8 is arranged in outside door leaf 2 or doorframe 1 with 7 opposite position of stiffening plate
Portion, and sealing element fixed part 8 is fixed in stiffening plate 7 by screw, the sealing element 9 is fixed at sealing element fixed part 8
On.By the form of the composition of said sealing unit, when sealing efficiency reduces, sealing element 9 or replacement can be very easily replaced
Sealing element fixed part 8 with sealing element 9.
As shown in figure 5, wherein the top of 1 inner concave of doorframe is arranged in sealing unit, stiffening plate 7 is arranged on 1 surface of doorframe
Inside, the rectangular shape of sealing element fixed part 8, is fixed by screws in stiffening plate 7, another side is fixedly installed sealing element on one side
9,9 end of sealing element is in diminishing taper, and the end vertical of the diminution is resisted against on door leaf 2.Sealing unit setting
Sealing element 9 touches door leaf 2, Ji Nengbao on the doorframe 1 of the opposite face with door leaf 2 at closing time, and when door leaf 2 and the closure of doorframe 1
Sealing is held, and too big pressure will not be applied to door leaf 2, i.e., sealing unit plays under natural conditions what door leaf 2 and doorframe 1 were closed
The effect of sealing reaches the outer peculiar smell of indoor isolating chamber, or the effect for forbidding foreign flavor indoors to flow out;And it will not opening to door leaf 2
It closes and causes resistance or frictional force, do not influence the normal use of fire resistant doorsets.Two rectangular sides of sealing element fixed part 8 are hinged
Connection, sealing element fixed part 8 can rotate an angle and fixation around the articulated section, when not needing sealing, sealing element fixed
Portion 8 rotates the angle, as shown in fig. 6, two sides release the seal shape of doorframe 1 and door leaf 2 with point-blank, being in 180 °
State.It is placed in 9 main body of sealing element in addition, the tapered end of sealing element 9 can retract, when not needing sealing, makes 9 end of sealing element
Portion retracts, and releases the sealing state of doorframe 1 and door leaf 2.
As shown in fig. 7, sealing unit is arranged in 2 edge of door leaf of 1 female parts of doorframe, the setting of stiffening plate 7 exists
2 interior surface of door leaf, sealing element fixed part 8 is in the shape of a frame, and middle section is fixed by screws in stiffening plate 7, and sealing element is fixed
It is surrounded inside the frame-shaped in portion 8 and is provided with sealing element 9,9 end of sealing element is in diminishing taper, and the end vertical of the diminution
It is resisted against on doorframe 1.Similarly, sealing unit setting is on door leaf 2 and vertical with doorframe 1, and door leaf 2 is close when being closed with doorframe 1
Sealing 9 touches doorframe 1, has not only been able to maintain sealing, but also will not apply too big pressure to doorframe 1, i.e., sealing unit is in door leaf 2 and doorframe
1 closure plays the role of sealing under natural conditions, reaches the outer peculiar smell of indoor isolating chamber, or the work for forbidding foreign flavor indoors to flow out
With;And resistance or frictional force will not be caused to the opening and closing of door leaf 2, the normal use of fire resistant doorsets is not influenced.The tapered end of sealing element 9
Portion, which can retract, to be placed in 9 main body of sealing element, when not needing sealing, is retracted 9 end of sealing element, is released doorframe 1 and door leaf 2
Sealing state.
2 outer surface of door leaf of fire resistant doorsets is 0.8mm cold rolling hot dip galvanizing steel plate, and inside is perlite, and door leaf 2 is being kept to have
In the case where some strength, fire spreading can be prevented.1 outer surface of doorframe is 1.2mm cold rolling hot dip galvanizing steel plate;Stiffening plate 7
With a thickness of 3mm;Sealing element fixed part 8 is cold-rolling galvanization steel plate, is made up of punching press, bending, baking vanish.
It should be understood that above-mentioned specific embodiment of the invention is used only for exemplary illustration or explains of the invention
Principle, but not to limit the present invention.Therefore, that is done without departing from the spirit and scope of the present invention is any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.In addition, appended claims purport of the present invention
Covering the whole variations fallen into attached claim scope and boundary or this range and the equivalent form on boundary and is repairing
