Embodiment Construction
[0022] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.
[0023] refer to Figure 1 ~ Figure 4 , The connection structure of the electric telescopic door of the present invention includes a machine head 10 , a door row 20 and a connecting piece 30 . The door row 20 can move back and forth under the drive of the machine head 10, so that the door row 20 can be expanded or contracted to realize the opening or closing of the electric telescopic door.
[0024] like Figure 1 ~ Figure 4 As shown, the machine head 10 is the traction mechanism of the door row. In the present invention, the machine head 10 is a narrow body machine head, and its width is smaller than the existing electric telescopic door machine head. The front and rear wheels 13 of the front wheel and the rear wheel 13 are respectively provided at the bottom of the nose 10, on the side perpendicular to the axles ...

Disclosed is a connecting structure of an electric retractable door. The structure comprises a machine head and a door row. The connecting structure is characterized in that the door row is formed bymovably connecting a plurality of main frames, a plurality of auxiliary frames and a plurality of crossed connecting rods for connecting the main frames with the auxiliary frames. The main frames include the first main frame provided with small walking wheels, the second main frame provided with large walking wheels and the wheel-free main frame. The side, connected to the door row, at the lower end of the machine head is provided with a U-shaped containing frame for containing the front portion of the door row. The machine head is connected with the first main frame at the front end of the door row through a connecting piece, and the large walking wheels of the second main frame and the back wheel of the machine head are located at the same straight line, When the door row is retracted, the front portion of the door row enters the containing frame at the lower end of the machine head. When the door row is retracted in place, the multiple large walking wheels and the back wheel of themachine head get close to each other, and the multiple small walking wheels are arranged at the inner sides of the multiple large walking wheels in a staggered mode and get close to each other. The connecting structure is more compact after the door row is retracted in place and cleaner , attractive and fashionable in appearance.
Description
【Technical field】 [0001] The invention relates to an electric telescopic door, in particular to a connection structure of an electric telescopic door which can effectively reduce the retracted length of the door row. 【Background technique】 [0002] At present, electric telescopic doors are favored by people for their flexible expansion and contraction, easy manipulation and changeable shapes, and are widely used in institutions, schools, enterprises, stadiums and other places, and can effectively manage vehicles and personnel entering and leaving. . The traditional electric retractable door includes a machine head and a retractable door row driven by the machine head, wherein the door row is connected by a main frame, a sub frame and a cross link. The door row of the traditional retractable door is as wide as the machine head, and the door row is directly arranged at the rear of the machine head after shrinking in place, and the running wheels at the bottom of each frame of...
