Abstract

The utility model relates to an automatic telescopic door, of which a compensator is arranged on a sliding rolling wheel shaft below door bottom. The utility model is characterized in that the door is designed to form a tower structure for reducing the centroidal position of the door and improving the wind resistance ability and stability. The sliding end of the compensator of the rolling wheel shaft is provided with an inverted U-shaped guide sleeve for replacing the conventional design of a milling groove on the sliding rolling wheel shaft. Hollow stainless steel pipes can be used to make into the sliding rolling wheel shaft. The utility model has the advantages of novel structure, shapely figure, strong artistic feeling, strong wind resistance ability, rot resistance, wear resistance, long service life, etc.

Description

Tower automatic retractable door

The utility model relates to a kind of safety door, especially the flexible automatically retractable door of door body.

Retractable door in the market is of a great variety, but its structure is roughly the same, and the common defective that exists is that its wind loading rating is poor, and some center of gravity offset distance is big, move not steady, in Shandong, the accident that automatic retractable door is blown down by strong wind once took place on ground such as Fujian, Jilin.In addition, at the sliding end operated by rotary motion sliding pin of expansion bend, make it to reciprocatingly slide in the sliding tray of corresponding configuration on rolling shaft, this kind structure will be carried out the machining of groove, and is not easy to the stainless steel material that adopts rotproofness strong.

The purpose of this utility model provides a kind of the body weight heart on the lower side, can keep the tower automatic retractable door of its stability under powerful wind-force.

The purpose of this utility model is achieved in that the utility model comprises the draw-gear that is made of devices such as tractor, traction wheel, indicator lamps, one side of draw-gear is hinged with the door body, a relative side of per two fan door leafs is hinged, opposite side is hinged with a side of two door bodies respectively, the door body is tower shape, door body bottom side is fixed with rolling shaft, and scroll wheel is installed on the two ends of rolling shaft, and places on the track.Per two mutual cross-articulation of hinge-rod are provided with the formation expansion bend, two fixed ends of expansion bend are hinged on an end of rolling shaft respectively with the fixed end of adjacent expansion bend, the sliding end of expansion bend is hinged with the sliding end of adjacent expansion bend respectively, " U " type guide pin bushing is installed down on the sliding end, " U " type guide pin bushing that falls is enclosed within on the rolling shaft between two anchor points, and can slide thereon.

The utility model is because of the door body is designed to tower shape, and is promptly up-narrow and down-wide, makes a body weight heart on the lower side, and whole center of gravity eccentric throw reduces, and has strengthened stability when having improved wind loading rating greatly.On the other hand, install " U " type guide pin bushing on the utility model rolling shaft on the sliding end of expansion bend, replace milling on the rolling shaft conventional design of groove with this, deducted the machining of groove, be convenient to adopt hollow stainless-steel pipe to make the slider roller axle, can realize whole stainless steel design.

The utlity model has novel structure, luxurious style, characteristics such as artistic feeling is strong, wind loading rating is strong, anticorrosive anti-wear, long service life.

Below in conjunction with drawings and Examples the utility model is done further detailed description.

Fig. 1 is overall appearance figure of the present utility model.

Fig. 2 is door body structure figure of the present utility model.

Fig. 3 is the utility model expansion bend schematic diagram.

Fig. 4 is that expansion bend A-A is to view.

By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be known, the utility model comprises the draw-gear that is made of tractor 11, traction wheel 12, indicator lamp 13 etc., one side of draw-gear is hinged with door body 1, relative sides of per two fan door leafs 2 are hinged, and opposite side is hinged with a side of two door bodies 1 respectively, and a door body 1 is tower shape, promptly up-narrow and down-wide, door body 1 bottom side is fixed with rolling shaft 4, and scroll wheel 3 is installed in the two ends of rolling shaft 4, and places on the track.Per two hinge-rods, 6 mutual cross-articulation are provided with and form expansion bend 5, two fixed ends 7 of expansion bend 5 are hinged on an end of rolling shaft 4 respectively with the fixed end 7 of adjacent expansion bend 5, the sliding end 8 of expansion bend 5 is hinged with the sliding end 8 of adjacent expansion bend 5 respectively, " U " type guide pin bushing 10 is installed down on the sliding end 8 is enclosed within on the rolling shaft 4 between two anchor points 9, and can slide thereon.
