Technical field
The present invention relates to the sealing device of door, specifically a kind of automatic sealing device
.
Background technology
The existing sealing device for door is generally mounted on door leaf or doorframe.In time closing the door, the mechanical device of sealing device will start, thus makes weather strip move to sealing state.In such state, weather strip will be adjacent on floor, doorframe, ceiling or wall and door leaf.In weather strip, be usually filled with heat expanding material between having between flexible seal member and fixed part, this material heat when catching fire can expand.Can gap be blocked after material expansion, thus isolated smog.
Sealing device mentioned above can ensure the effect playing isolated smog when catching fire substantially, but except filling heat expanding material, reach the effect every cigarette fire insulation desirable within the specific time, also need to take more measure.An effective way is when mounting sealing device, uses fixed angle plate to strengthen fixing (fixed angle plate and the screw) of shell at the end of sealing device.
If amount and the corresponding weather strip of the heat expanding material of filling do not prepare, also there will be another one problem.The heat expanding material of such as filling is too many, has flexible seal member and bursts because heat expanding material heat when catching fire expands or split, thus can not play original sealing effectiveness.Also may just because of this and produce gap, and smog is permeated.Heat expanding material also may spill from sealing besides, does not thus reach the fire insulation effect of expection.In other words, the fire insulation dynamics of door can be affected.
In addition, also must consider when sealing, if heat expanding material will be filled in weather strip, same weather strip, the plasticity adding the seal member of heat expanding material is smaller than the weather strip not adding heat expanding material, because the heat expanding material of solid does not have elasticity or elasticity very little.
In view of the limitation that above-mentioned mentioned existing sealing device exists, use during sealing device and need to spend the more time to do meticulous planning work, thus demand can have a kind of need little or the sealing device that do not need to design especially the isolated smog just can installed.
Further, be exactly many in common knowledge, shell and weather strip can produce resonance because of external reason under special circumstances, produce harmful effect to the sound insulating seal effect of sealing device entirety.This situation also should be got rid of.
Summary of the invention
In order to solve the above-mentioned prior art Problems existing mentioned, the invention provides a kind of automatic sealing device, this device has a shell, a mechanical device and a weather strip, its weather strip is connected together by mechanical machine parts and its shell, weather strip can, to the longitudinal direction motion moved towards relative to shell under the effect of mechanical machine parts, make weather strip become sealing state from static state; When automatic sealing device is positioned at static and sealing state, all at least leaves a space between shell and weather strip, have the filler of filling at least one at least partially in a space at least.
Described filler can be thermal insulation material and/or be heat expanding material.
Described filler be preferably filled in the direction of motion of weather strip from sealing state to static state that be positioned at space above weather strip.Generally this is spatially located at a shape and is mostly one of the web of U-shaped shell and weather strip in H type or between a web of U-shaped fixed part.Can be fenced up by the long limit of the web of H type fixture and fixture at three when this space is maximum.
The sealing device that the filler that space between shell and weather strip adds may make this be made up of shell, mechanical device and weather strip changes audio frequency, in other words, described filler by the change to the audio frequency of sealing device own, and stops the sound in this audiorange caused because of foeign element when normal use.
Put filler like this and also have another one advantage, be exactly when heat expanding material filler in high compression swelling time, weather strip can be pressed towards the direction of sealing state from static state.Heat expanding material filler not only closes sealing device, smog can not be passed through between shell and weather strip, and this heat expanding material also presses to sealing state weather strip, even if mechanical device is malfunctioning because of the effect of high temperature like this, weather strip also large area can be attached to contact surface and gets on.Because heat expanding material filler is not placed on inside seal member, seal member also just can not burst or tear when filler expands.
In automatic sealing device, filler can be fixed on shell in whole or in part.
As another preferred version, also all or part of filler can be fixed on weather strip.
The filler be placed in automatic sealing device can be distributed in the whole length of sealing device shell and/or weather strip.Preferably, also the single individuality made with filler can be separated one by one in the space be emitted between shell and weather strip.
The exquisiteness of the distance between the amount of the filler be placed in described space and/or filler body being calculated, requiring that the filler expanded when catching fire all or almost can all be full of whole space exactly.To the meticulous selection of intumescent filler thing be require when catching fire, filler can expand to desirable direction, thus reaches the sealing function of desirable stop smog.
Filler can by an adhesive tape, or one or several segment of tape composition.Such filler has the function of expansion and sound insulation.
Heat intumescent filler thing preferably can without pressure expansion, and when catching fire, dilated filler can make the mechanical performance of sealing device be protected.When catching fire, particularly mechanical device can be protected from the infringement of high temperature without pressure intumescent filler thing.Dilated filler is as the isolation layer of a mechanical device, thus protection sealing device is not by baked wheaten cake thoroughly.
Automatic sealing device of the present invention, has good sealing performance, fire insulation every cigarette and soundproof effect good, and cause the explosion of seal member when avoiding heat intumescent material swells or tear.
