Abstract

The utility model relates to an electric telescopic door with an integral three-round isolated stand single-rail double-roller guide device, which belongs to a building facility. The utility model has the main characteristics of attractive appearance for using an integral three-round isolated stand, and no precedent in China so far. The utility model is not provided with double guide rails for a land wheel, a land wheel rolls directly on the ground, and a telescopic door body guide uses a single-rail double-roller guide for the flexible and portable operation of a door body. The telescopic door with an integral three-round isolated stand single-rail double-roller guide device is suitable to be used for gates of enterprise units and business units, and cement and furring brick pavements, particularly the furring brick pavements.

Description

The two roller guiding of monolithic three-arc stand single track electric extendable door

The utility model relates to a kind of improved electric extendable door, is suitable for the gate of doing enterprise and institution.

Electric extendable door is to obtain a kind of novel gate promoted in recent years at home.The two roller guiding mechanisms (Fig. 1, Fig. 4) of monolithic three-arc stand of adopting on the utility model product (Fig. 1, Fig. 2) and single track, at home beyond example.

The purpose of the utility model product is to improve existing electric extendable door on the market, makes its structure more reasonable, moves more light and flexible, and is handsome in appearance, shows unique characteristics.

The technical scheme of the utility model product is seen Fig. 1, and is the same with the existing retractable door in market, with many hinges with many pull bars (2) respectively in vertical and horizontal plane (A-A analyses and observe), be hinged to two groups of parallelogram.Go up drilling in monolithic three-arc stand (1), be enclosed within on horizontal hinge shaft (5) and the lower vertical hinge, roller is equipped with at the hinge two ends of the upper and lower of horizontal hinge shaft (5).The inboard riveted joint of stand vertical plane has 4 guide grooves, and during door body opening and closing, the hinge of dress roller moves relative to guide groove is upper and lower.Tailstock (7) is fixed on the ground, and the anterior Electric Traction head (6) that connects is loaded onto land wheel (3), (4) under head and the stand, utilize the scalability of parallelogram, and it is big just to have constituted length of run, the little electric extendable door of volume after the condensation.Obvious characteristic of the present utility model adopted exactly unprecedented monolithic three-arc stand on the market (Fig. 1, Fig. 2).Three circular arc portions are arranged in the stand, on a level metal rectangular pipe, bend moulding.All the circular arc outer radius is about 135 millimeters, 180 ° at top center of arc angle, two center of arc angles, bottom are about 60 °, and the straight line portion length under the circular arc of bottom is about 145 millimeters, the stand lower width is about 560 millimeters, and the user is highly looked in stand to be needed to make 1200～2000 millimeters.In addition, existing retractable door is to lay two parallel guide rails on the ground on the market, makes on land wheel and corresponding groove of guide rail or step, is stuck between two guide rails, with control gate running body direction.The utility model has adopted the two roller guiding mechanisms (Fig. 1, Fig. 4) of single track.Guiding mechanism is contained in head and stand bottom.Second wheel (8) moves along guide rail at guide rail (10) both sides control gate body, and rolling bearing (9) is housed in the roller hole, the frictional resistance when having reduced the door running body effectively.Second wheel centre distance=roller diameter+guide rail is wide+and 2 millimeters.

The utility model product has following beneficial effect:

The stand of monolithic three-arc, rational in infrastructure, handsome in appearance, have a distinct characteristic, and can on market, existing two kinds of basic flower forms (Fig. 1, Fig. 3) of compiling go up general; The two roller guiding mechanism frictional resistance of single track are little, make a running body light and flexible; Adopt soft high-abrasive material as land wheel, can directly on the cement floor, move.

Manual drawings attached 1～4, Fig. 1 is the whole structural scheme figure of the utility model " the two roller guiding of monolithic three-arc stand single track electric extendable door ", Fig. 2 is the monolithic three-arc stand moulding figure of the uniqueness of this product employing, Fig. 3 is the retractable door that can adopt the another kind of form of monolithic three-arc stand, and Fig. 4 is the guiding mechanism structure chart that the utility model retractable door adopts.

The key that realizes the utility model product is the moulding that bends of monolithic three-arc stand, can utilize the circular arc molding mold to bend on general motor-driven bending machine, and small-scale production also can be made easy manual angle pipe equipment by oneself, bends with manpower.

Claims

1. the two rollers guiding of monolithic three-arc stand single track electric extendable door, the same with the existing retractable door in market, with many hinges with many pull bars (2) respectively in vertical and horizontal plane (A-A analyses and observe), be hinged to two groups of parallelogram, go up drilling in monolithic three-arc stand (1), be enclosed within on horizontal hinge shaft (5) and the lower vertical hinge, roller is equipped with at the hinge two ends of the upper and lower of horizontal hinge shaft (5).The inboard riveted joint of stand vertical plane has 4 guide grooves, during door body opening and closing, the hinge of dress roller moves relative to guide groove is upper and lower, tailstock (7) is fixed on the ground, and the anterior Electric Traction head (6) that connects is loaded onto land wheel (3), (4) under head and the stand, utilize the scalability of parallelogram, it is big just to have constituted length of run, the little electric extendable door of volume after the condensation, and the feature of the utility model product is:
