The purpose of this utility model is to overcome the deficiencies in the prior art a kind of folding automatic door is provided, and not only Men folding degree is big, handsome in appearance, and safe and convenient to use.

A kind of automatic folding door described in the utility model, it is characterized in that: it comprises the doorframe column that is located at the doorframe both sides, the fixedly connected assembly of machine beam, the doorframe rotary column, drive sprocket, driven sprocket, chain, support roller, supporting component, the machine beam, the electrical equipment control assembly, Power Component and collapsible gate body, described machine beam is fixed on the top of both sides doorframe column by the fixedly connected assembly of machine beam, two doorframe rotary columns are vertically mounted on the doorframe column inboard respectively, each doorframe rotary column upper end respectively with drive sprocket, the main shaft of driven sprocket links to each other, the lower end links to each other with the ground axle bearing, chain connects drive sprocket and driven sprocket, the main shaft of support roller is located on the machine beam, the support roller wheel body is meshed with chain and is supporting chain, the collapsible gate body comprises two parts that left and right sides can be split, and two parts are fixedlyed connected with the doorframe rotary column of both sides respectively; Power Component is arranged on the machine beam and is connected with drive sprocket provides power, and the electrical equipment control assembly then is electrically connected its action of control with Power Component.

Folding door is generally made 2 fan door leafs and two kinds of structures of 4 fan door leafs.When making 2 fan door leafs, door leaf is fixedlyed connected with the doorframe rotary column of both sides respectively; When making 4 fan door leafs, in two parts that left and right sides can be split, various piece comprises inner door body and outer door body again, wherein the outer door body is fixedlyed connected with the doorframe rotary column, then be connected through the hinge between inner door body and the outer door body, the top of inner door body is fixed with pulley, slides in the groove of pulley on the door beam during operation.

Above-mentioned Power Component comprises motor and the speed-changing gear box that is attached thereto, and speed-changing gear box is connected with the driven gear that is fixed on the drive sprocket below.

Motor can adopt the slow-speed of revolution, and the high torque DC Brushless Motor owing to reduced gear ratio, has therefore reduced the noise of gear operation.

In order to keep the rigidity of machine beam under the large span, on the machine beam, be provided with the supporting component of reinforcement effect.

On the machine beam, electromagnetic lock can also be set, improve the safety of folding door with collapsible gate body correspondence position.

Advantage of the present utility model:

1, the folding degree of door body is big, is specially adapted to less place, door opening space;

2, adopt the slow-speed of revolution, the high torque DC Brushless Motor owing to reduced gear ratio, has therefore reduced the noise of gear operation;

3, simple in structure, easy for installation.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Five, the specific embodiment

As depicted in figs. 1 and 2, a kind of automatic folding door described in the utility model, it comprises the doorframe column 1 that is located at the doorframe both sides, the fixedly connected assembly 2 of machine beam, doorframe rotary column 3, drive sprocket, driven sprocket, chain 4, support roller 6, supporting component 7, machine beam 9, electrical equipment control assembly 10, Power Component 11 and collapsible gate body, machine beam 9 is fixed on the top of both sides doorframe column 1 by the fixedly connected assembly 2 of machine beam, two doorframe rotary columns 3 are vertically mounted on doorframe column 1 inboard respectively, each doorframe rotary column 3 upper end respectively with drive sprocket, the main shaft of driven sprocket links to each other, the lower end links to each other with the ground axle bearing, chain 4 connects drive sprocket and driven sprocket, the main shaft of support roller 6 is located on the machine beam 9, the support roller wheel body is meshed with chain 4 and is supporting chain 4, the collapsible gate body comprises two parts that left and right sides can be split, each several part divides inner door body and outer door body again, wherein the outer door body is fixedlyed connected with doorframe rotary column 3, then be connected through the hinge between inner door body and the outer door body, the top of outer door body is fixed with pulley, slides in the groove of pulley on the door beam during operation; Power Component 11 is arranged on the machine beam 9 and is connected with drive sprocket provides power, and 10 of electrical equipment control assemblies are electrically connected its action of control with Power Component 11.Power Component 11 comprises motor and the speed-changing gear box that is attached thereto, and speed-changing gear box is connected with the driven gear that is fixed on the drive sprocket below.On machine beam 9, be provided with electromagnetic lock 8 with collapsible gate body correspondence position.Door body of the present utility model becomes doorframe by special-purpose made from aluminium profile, fixes tempered glass with rubber strip, and the folding door periphery all has the rubber strip sealing.
