Abstract

The utility model provides linkage rolling curtain doors, comprising rolling curtains moved in guide grooves on the both sides of door frames, reels which are connected with the rolling curtains and arranged above the door frames, and a driver which is connected with the reels and is used for driving the reels to rotate. The linkage rolling curtain doors are characterized in that the reels which are all connected through a coupling constitute a rotary shaft for realizing the linkage of at least two rolling curtain doors. The utility model overcomes the defect that the existing rolling curtain door having high cost and complicated operation can not be used to separate or hinder from timely the ignition source, and the defect is caused by the fact that one door is matched with one driver in prior art. A plurality of rolling curtain doors are simultaneously opened or closed in the form of the linkage, which can be realized through a driver. Thus, the investment cost and the running cost reduced, and the operation and maintenance work is simplified. In addition, the task of separating and hindering from the ignition source can be completed simultaneously in the short time by the rolling curtain doors, and the fire prevention property of the utility model is realized fully.

Description

A kind of interlock rolling door

Technical field

The utility model relates to a kind of electric rolling door, especially a kind of rolling door with fire-proof function.

Background technology

At present, in the building that the retail shop of a plurality of fire resistance rolling shutter doors, market, warehouse and other place are arranged, each fire resistance rolling shutter door is all by a roller shutter driving device controls, this mechanism has not only increased the cost and the cost of rolling door, and operation control is loaded down with trivial details, fault rate is high, maintenance cost is high, even more serious is effectively to bring into play the effect of the peculiar isolation of fire resistance rolling shutter door, the blocking-up intensity of a fire when fire takes place in flakes.Therefore, be necessary prior art is improved.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and provide a kind of and can open and close a plurality of rolling door simultaneously, and simple to operate, the interlock rolling door that cost is low.

The utility model is finished by following technical proposal: a kind of interlock rolling door, be included in the roller shutter that moves in doorframe two side guidances, link to each other with roller shutter and place the spool of doorframe top, link to each other with spool and drive the driver of its rotation, it is characterized in that each spool is linked as the rotating shaft that can make the interlock of at least two door frame rolling door by shaft joint, so that under a driver drives, make each spool drive corresponding rolling door and open simultaneously or close.

Described shaft joint is by an axle sleeve, and the fixture of being located at these axle sleeve two ends constitutes, so that two spools are fixed on the axle sleeve two ends, thereby constitutes vertical bar type interlock spool.

The two ends of described shaft joint are respectively equipped with on it plush copper of band installing hole, and the plush copper face is vertical mutually, so as with spool hinged after, form vertical bar shaped universal driving shaft or corner shape universal driving shaft as required.

Above-mentioned two kinds of shaft joints can be installed one or more according to actual needs, and one or more groups of two kinds of combinations perhaps is installed.

Described driver comprises motor, reduction box, belt pulley, belt and the belt pulley coaxial with spool, so that under driven by motor, makes the spool interlock by reduction box, belt pulley and belt, thus open and close when finishing all rolling door.

The utility model compared with prior art has following advantage and effect: adopt such scheme, the cost height, the operation that bring because of a driver that has overcome that prior art exists be loaded down with trivial details, can not in time isolate or block a series of mesopodiums such as burning things which may cause a fire disaster, only need can be realized the united opening of many door frames rolling door simultaneously with a driver or close, investment and running cost had both been reduced, simplify the operation again and maintenance, maintenance work, make fire resistance rolling shutter door can finish the work of isolation, blocking-up burning things which may cause a fire disaster at short notice simultaneously, fireproof performance is given full play to.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.

Among the figure, 1 is the guide groove of doorframe both sides, 2 is roller shutter, can in guide groove 1, move up and down, 3 is spool, the one end is fixed on the doorframe top, and the other end is fixed on the doorframe top by bearing 6, and spool 3 links to each other with main shaft 5 by belt 4, main shaft 5 links to each other with motor and reduction gearbox output shaft, 6 is bearing, is installed in the bearing support of doorframe top, and 7 is shaft joint, fixedly hinge 8 by axle sleeve and two ends thereof constitutes, by hinge 8 spool 3 is fixed on the two ends of shaft joint 7, and passes through pin 9 lockings, 10 is another shaft joint, its two ends are respectively equipped with its surface plush copper 11 of 90 ° each other, plush copper is provided with installs with through hole 12, by hinge 8 spool 3 is fixed on the two ends of shaft joint 10, and passes through pin 9 lockings.

Claims

1, a kind of interlock rolling door, be included in the roller shutter that moves in doorframe two side guidances, link to each other with roller shutter and place the spool of doorframe top, link to each other with spool and drive the driver of its rotation, it is characterized in that each spool is linked as the rotating shaft that at least two door frame rolling door are linked by shaft joint.

2, interlock rolling door according to claim 1 is characterized in that described shaft joint by an axle sleeve, and the fixture of being located at these axle sleeve two ends constitutes.
