Abstract
The utility model discloses an airtight operation device of a gas-tight door, which comprises door tracks and hanging wheels and is characterized in that the door tracks are double tracks, and the two hanging wheels which respectively correspond to the door tracks with the double tracks and are used for being fixed on the front portion and the rear portion of the gas-tight door are located on the door tracks with the double tracks. The door tracks with the double tracks are composed of parallel guide sections and airtight guide sections between which movable connection structures are arranged. The other ends of the airtight guide sections are fixed in guide grooves which are oblique downwards and inwards in a sliding mode. When the gas-tight door is operated to the airtight guide sections, the door is in downward and inward motion conveniently and stably so as to be attached tight to an inside wall and the ground. During opening operation and airtight operation of the gas-tight door, the airtight operation device of the gas-tight door can ensure that the gas-tight door is stably separated from the wall and the ground or be airtight, avoids friction type contact of sealing strips, avoids abrasion of the sealing strips and prolongs service life.
Description
Technical field
The utility model relates to a kind of air tight door technology, the airtight running gear of particularly a kind of air tight door.
Background technology
Chinese patent 200920196217.9 discloses a kind of air tight door, and it comprises and is arranged on the guide locating device provided of body upper end, the lead that is arranged on a chute of body bottom and is slidingly matched with chute; Lead is positioned at a side in doorframe the place ahead; And be fixedly installed on the bottom surface, a side side of chute vertically is provided with to deviating from first inclined-plane that the doorframe direction tilts, and the opposite side side of chute is provided with second inclined-plane parallel with first inclined-plane; Form a tip chute between first inclined-plane and second inclined-plane; Be circular arc with the contacted part in first inclined-plane and second inclined-plane on the lead, this structure is only required with the distance of doorframe relatively accurate, and less demanding along the installation site of door body moving direction to being fixed on lead and auxiliary lead on the bottom surface; Allow deviation, be convenient to installation.But the setting of the guide frame of this surface-based lead is unfavorable for the place that hygienic requirements is high, and the amplitude of its airtight operation is little, can not play good obturation effect.
The utility model content
The purpose of the utility model is to provide a kind of airtight performance high for the deficiency that solves above-mentioned prior art, can not produce the airtight running gear of air tight door of wearing and tearing to weather strip during airtight operation.
To achieve these goals; The airtight running gear of a kind of air tight door that the utility model designed comprises door track and hanging wheel, it is characterized in that described door track is a double track; Corresponding respectively two hanging wheels that are used for fixing before and after air tight door on the door track of double track; The door track of said double track is made up of parallel guide section and airtight guide section, is movable connection structure between parallel guide section and the airtight guide section, and the other end of airtight guide section slides and is fixed in downward, the intilted gathering sill.When making air tight door run to airtight guide section, convenient, reposefully downwards and inwardly motion, thus make door be adjacent to inboard metope and ground.
The steady unlatching of air tight door for ease, an end that is located at the airtight guide section in the gathering sill is provided with lifting rope, and the other end of lifting rope is provided with returning spring, and lifting rope can be connected with returning spring through directive wheel.
The airtight running gear of the air tight door that the utility model provides, hanging wheel operates in respectively on the door track of being made up of double track separately before and after it, and the door track of double track composition all is arranged to parallel guide section and airtight guide section separately; At closing time; Hanging wheel at first runs parallel on the parallel guide section of door track separately, and when hanging wheel moves to when needing closed position, hanging wheel gets into the airtight guide section of door track; The door track of airtight guide section simultaneously inwardly, downwards to the hanging wheel guiding, make the steady airtight operation of air tight door; Otherwise, when air tight door is opened, the airtight guide section of door track simultaneously outwards, upwards to the hanging wheel guiding, air tight door is steadily opened, then the parallel guide section of door track to hanging wheel carry out parallel conductive to, open air tight door.
Adopt between airtight guide section and the parallel guide section and flexibly connect; And the other end of airtight guide section slides and is fixed in downward, the inside gathering sill; Airtight guide section is receiving under the hanging wheel action of gravity that has air tight door; Its slip be fixed in the gathering sill an end along gathering sill downwards, inwardly slide, thereby make hanging wheel and air tight door inwardly, operation downwards.
On airtight guide section, lifting rope is set; When air tight door is opened operation; Lifting rope is mentioned the end of airtight guide section in gathering sill, and airtight guide section outwards carries out, upwards leads hanging wheel under the guiding of gathering sill, and airtight guide section resets under the lifting rope effect simultaneously.
The airtight running gear of the air tight door that the utility model provides; When the unlatching of air tight door and airtight operation, can guarantee the steady disengaging on air tight door and metope and ground or airtight, avoid the contact of weather strip generation friction-type; Avoid the weather strip wearing and tearing, improved its application life.

Fig. 3 is the gathering sill structural representation;
Fig. 4 is the downward and inside motion state sketch map of airtight guide section in the door track of double track.
Among the figure: door track 1, parallel guide section 11, airtight guide section 12, hanging wheel 2, air tight door 3, gathering sill 4, lifting rope 5, returning spring 6, directive wheel 7.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment:
Like Fig. 1, shown in Figure 2; The airtight running gear of the air tight door that present embodiment provides; Comprise door track 1 and hanging wheel 2, described door track 1 is a double track, corresponding respectively two hanging wheels 2 that are used for fixing in air tight door 3 front and back on the door track 1 of double track; The door track 1 of said double track is made up of with airtight guide section 12 parallel guide section 11; Between parallel guide section 11 and the airtight guide section 12 is movable connection structure, and like Fig. 1, shown in Figure 3, the other end of airtight guide section 12 slides and is fixed in downward, the intilted gathering sill 4.Be located on the end of the airtight guide section 12 in the gathering sill 4 and can be provided with lifting rope 5; The other end of lifting rope 5 is provided with returning spring 6; Lifting rope 5 is connected with returning spring 6 through directive wheel 7; Returning spring 6 air tight doors progressively make guide rail reset when opening operation, make air tight door steadily airtight during the airtight operation of air tight door.
As shown in Figure 4, airtight guide section is receiving under hanging wheel 2 actions of gravity that have air tight door 3, and its slip is fixed on, the inwardly slip downward along gathering sill of the interior end of gathering sill, thereby makes hanging wheel 2 drive air tight doors 3 inside, downward operations.
