Abstract
The utility model discloses a kind of fireproof door frame sealing strip, including：Elastomer, has u-shaped structure, and including at least elastomer fixed part, buffer part and clamping part, elastomer is PU expanded materials；Periostracum, the outer rim bag for prolonging elastomer are set.The purpose of this utility model is that dismounting is simple, wear-resisting resistance to pressure is good, also the sealing strip with fireproofing function.
Description
Technical field
It the utility model is related to door leaf technical field, and in particular to a kind of fireproof door frame sealing strip.
Background technology
The leakproofness of modern on the door proposes the requirement of higher, in addition to it should have good sound insulation, dust-break effect, door
Fan close when also to reduce as far as possible its generation noise, and the quality distance above-mentioned requirements of the door leaf of the prior art it is also poor compared with
Far.Since shutdown is larger to the impact of doorframe, after the shutdown of more subgravities so that existing seal aging, deformation, and it is existing
It can not play the role of fireproof in most of seals.
Chinese patent literature discloses 204677086 U of CN, the sealing strip on a kind of doorframe, including：Shell, elastomer,
Shell is arranged on outer elastomeric surface, and sealing strip is in g types.Shell is PE films, and elastomer is PU expanded materials.Said structure has
Relatively good sealing effect, but while sealing, its fire protecting performance does not have competitive advantage.
Utility model content
Therefore, the purpose of this utility model is that dismounting is simple, wear-resisting resistance to pressure is good, the also sealing with fireproofing function
Bar.
A kind of sealing strip for door frame provided by the utility model, including：
Elastomer, has u-shaped structure, including at least elastomer fixed part, buffer part and clamping part；
Periostracum, the outer rim bag for prolonging the elastomer are set.
Expansion stone mill layer is embedded in the outer rim of the fixed part.
Alternatively, the expansion stone mill layer outer rim is equipped with glue-line.
Alternatively, the elastomer is PU expanded materials.
Technical solutions of the utility model, have the following advantages that：
Fire proof sealing strip provided by the utility model, is used cooperatively with doorframe and door leaf, is closed by imitating gravity several times
Door experiment, door body still maintain good sealing effect；PE film+PU expanded materials make composite seal bar, have it is wear-resisting,
Pressure-resistant, cold-resistant, heat-resisting performance, also causes sealing performance almost Perfect between doorframe and door leaf；Unique u-shaped design, is embedded in
It is more beautiful after in the airtight groove of doorframe, it is conveniently replaceable, realizes dynamic sealing；The sound absorption function of PU expanded materials, improves door
The soundproof effect of body；Cold environment can also keep splendid elasticity, solve because high/low temperature change and caused by sealing performance reduce；
Expansion stone mill layer possesses beyond the excellent performances such as native graphite cold-hot in itself, corrosion-resistant, self-lubricating, also with native graphite
Unexistent softness, compression resilience, adsorptivity, expanded graphite meet high temperature can 150~300 times of moment volumetric expansion, by sheet
It is changed into vermiform, porous and bend so that loosely organized, expanded surface area, surface energy improve, the power enhancing of absorption crystalline flake graphite,
It can be voluntarily fitted together between quasiflake graphite, so add its flexibility, resilience and plasticity, therefore have and more preferably prevent
Fiery bar expansion multiplying power, fire protecting performance are more excellent.
Brief description of the drawings
, below will be right in order to illustrate more clearly of the utility model embodiment or technical solution of the prior art
Embodiment or attached drawing needed to be used in the description of the prior art are briefly described, it should be apparent that, describe below
In attached drawing be the utility model some embodiments, for those of ordinary skill in the art, do not paying creativeness
On the premise of work, other attached drawings can also be obtained according to these attached drawings.
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model and door body cooperation schematic diagram.
Embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model part of the embodiment, instead of all the embodiments.Based on the embodiment in the utility model, sheet
Field those of ordinary skill all other embodiments obtained without making creative work, belong to this practicality
Novel protected scope.
, it is necessary to explanation in the description of the utility model, term " " center ", " on ", " under ", it is "left", "right", " perpendicular
Directly ", the orientation of the instruction such as " level ", " interior ", " outer " or position relationship are based on orientation shown in the drawings or position relationship, are only
Described for the ease of description the utility model and simplifying, rather than instruction or imply signified device or element must have it is specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in the description of the utility model
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；Can mechanically connect or be electrically connected；It can be directly connected, can also be indirectly connected by intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning of the language in the utility model.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not forming conflict can be combined with each other.
Embodiment 1
A kind of sealing strip for door frame provided in this embodiment, it is shown in Figure 1, including：Elastomer 1, has u-shaped structure, extremely
Include elastomer fixed part 12, buffer part 11 and clamping part 13 less, elastomer 1 is PU expanded materials；Periostracum 5, prolongs elastomer 1
Outer rim bag set.
Preferably, expansion stone mill layer 2 is embedded in the outer rim of fixed part 12；2 outer rim of expansion stone mill layer is equipped with layers of two-sided
3。
It is shown in Figure 2, above-mentioned sealing strip for door frame is embedded in the airtight groove 4 of doorframe, is had the characteristics that convenient for disassembly and assembly.
Obviously, the above embodiments are merely examples for clarifying the description, and the restriction not to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
