Abstract

The utility model discloses a mobile fireproof door, which is formed by assembling a fireproof door puller (1), a chain (2), guiding small sprocket wheels (3), a pulley wheel (4), an I-beam track (5), an evacuating small door (6), a door leaf closer (7), a fireproof door panel (8), a guiding groove (9) and a supporting bracket (10). The I-beam track (5) and the supporting bracket (10) are welded into a whole and are further fixed on a wall body by using expansion bolts, and the guiding small sprocket wheels (3) are symmetrically mounted on the I-beam track (5) and at two ends of the I-beam track (5). Compared with a product in the prior art, the mobile fireproof door provided by the utility model has the main advantages that the mobile fireproof door is movable; the space and the ground are occupied less; the application range of using the mobile fireproof door for civil buildings such as emporiums, storehouses, assembly halls, or places of amusement, and the like, is wide; the use is flexible and reliable; the fireproof door panel is provided with the evacuating small door, so that the escape is convenient; and simultaneously, the overall structure of the mobile fireproof door is attractive and compact.

Description

Portable labeled door

Technical field

The utility model belongs to fire fighting equipment, is specifically related to a kind of labeled door.

Background technology

In the civil building that is used as market, storehouse, assembly hall or public place of entertainment etc., generally all be provided with the labeled door that fire-fighting is used, at present common commonly used be fire curtain or fixed labeled door.Fire curtain and fixed labeled door all need to be fixed on relevant fire prevention cuts off and passage on, necessary active channel and bigger space, the above-mentioned civil building that has can't be installed fire curtain or fixed labeled door because of interior sky or insufficient height at all; And the labeled door of prior art is unidirectional type push form basically, promptly fixed the opening direction of escape, causes certain difficulty in case the fire alarm meeting takes place to the survivor; In addition, the labeled door of prior art also seems not attractive in appearance, not compact on general structure.

Summary of the invention

At the above-mentioned defective that prior art exists, propose a kind of portable labeled door of meter, make it to take up room less and ground, use is flexible, reliable, and escape is convenient, and structure is attractive in appearance, compact.

Technical solution adopted in the utility model is as follows.

A kind of portable labeled door is characterized in that:

1) it is assembled by fire rated roller shutter machine, chain, guiding minor sprocket, pulley, i beam track, evacuation wicket, door leaf door closer, fireproof door plate, guide groove and bearing support;

2) i beam track and bearing support are welded as a whole and are fixed on the body of wall with expansion bolt, and guiding minor sprocket symmetry is installed in the top and two ends of i beam track;

3) the fire rated roller shutter machine is provided with hinge wheel, and the fire rated roller shutter machine is fixed on and makes the corresponding position of hinge wheel and i beam track centre top;

4) evacuate wicket and be opened in the fireproof door plate middle and lower part, latent close being installed in of door leaf door closer evacuated above the wicket, and the uniform symmetry of pulley is fixed on above the fireproof door plate, and is shelved on the i beam track;

5) chain is nibbled the guiding minor sprocket on hinge wheel on the fire rated roller shutter machine and i beam track, and the two ends of chain is fixed on two ends above the fireproof door plate, and guide groove and fireproof door plate are complementary and are fixed on the corresponding body of wall.

The portable labeled door of the utility model structure, fireproof door plate can be hidden in the sandwich wall as normality, in case there is fire alarm promptly to start the fire rated roller shutter machine, make the hinge wheel on the fire rated roller shutter machine do forward rotation, thereby driving chain is drawn out to fireproof door plate with guide groove in the sandwich wall and meshes, passage cut off and reach the fire prevention purpose very soon, can push open fast simultaneously evacuate wicket door leaf in time with evacuating personnel, then by the door leaf door closer with the door leaf quick closedown; Another mistake makes the hinge wheel on the fire rated roller shutter machine do backward rotation to starting the fire rated roller shutter machine after removing fire alarm, fireproof door plate is drawn in from passage is returned to normality in the sandwich wall thereby drive chain.

The portable labeled door of the utility model is compared with prior art products, and its major advantage is: it is removable, takes up room and ground applied widely to civil building less; Use flexibly, reliably; Offer the evacuation wicket in fireproof door plate, escape is convenient; Its general structure is attractive in appearance, compact simultaneously.

Description of drawings

Fig. 1 faces the plane structure schematic diagram for the portable labeled door of the utility model;

Fig. 2 is the side-looking plane structure schematic diagram of the portable labeled door of the utility model.

In the drawings, 1-fire rated roller shutter machine, 1a-hinge wheel, 2-chain, the 3-minor sprocket that leads, the 4-pulley, 5-i beam track, 6-evacuates wicket, 7-door leaf door closer, 8-fireproof door plate, 9-guide groove, 10-bearing support.

The specific embodiment

Further specify the concrete structure of the portable labeled door of the utility model and its operating principle below in conjunction with accompanying drawing.

A kind of portable labeled door is characterized in that:

1) it is assembled by fire rated roller shutter machine 1, chain 2, guiding minor sprocket 3, pulley 4, i beam track 5, evacuation wicket 6, door leaf door closer 7, fireproof door plate 8, guide groove 9 and bearing support 10;

2) i beam track 5 is welded as a whole with bearing support 10 and is fixed on the body of wall with expansion bolt, and guiding minor sprocket 3 symmetries are installed in the top and two ends of i beam track 5;

3) fire rated roller shutter machine 1 is provided with hinge wheel 1a, and fire rated roller shutter machine 1 is fixed on and makes hinge wheel 1a and the corresponding position of i beam track 5 central upper;

4) evacuate wicket 6 and be opened in fireproof door plate 8 middle and lower parts, door leaf door closer 7 latent close being installed in are evacuated above the wicket 6, and pulley 4 uniform symmetries are fixed on above the fireproof door plate 8, and are shelved on the i beam track 5;

5) chain 2 is nibbled around hinge wheel 1a on the fire rated roller shutter machine 1 and the guiding minor sprocket 3 on the i beam track 5, and the two ends of chain 2 is fixed on two ends above the fireproof door plate 8, and guide groove 9 is complementary with fireproof door plate 8 and is fixed on the corresponding body of wall.

The portable labeled door of the utility model structure, fireproof door plate 8 can be hidden in the sandwich wall as normality, in case there is fire alarm promptly to start fire rated roller shutter machine 1, make the hinge wheel 1a on the fire rated roller shutter machine 1 do forward rotation, thereby driving chain 2 is drawn out to fireproof door plate 8 and guide groove 9 engagements in sandwich wall, passage cut off and reach the fire prevention purpose very soon, can push open fast simultaneously evacuate wicket 6 door leaf in time with evacuating personnel, then by door leaf door closer 7 with the door leaf quick closedown; Another mistake makes the hinge wheel 1a on the fire rated roller shutter machine 1 do backward rotation to starting fire rated roller shutter machine 1 after removing fire alarm, fireproof door plate 8 is drawn in from passage is returned to normality in the sandwich wall thereby drive chain 2.
