Problems solved by technology

[0003] Traditional retractable doors have complex procedures and cumbersome assembly processes, which cannot be assembled in unit modules. The products are basically assembled and connected by the factory, and the whole product is packaged and transported. The packaging volume is large, economical and costly.
In addition, the four-link telescopic frame used in traditional products has many nodes, requires high dimensional accuracy, and its manufacturing cost is high. In addition, due to insurmountable assembly errors, the overall structure of the entire telescopic door product is unstable. prone to unstable operation

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] This embodiment provides a retractable door, such as Figure 1~3 As shown, it includes a door box 1 and a telescopic door body 2 composed of connecting rods 4. The bottom of the door box 1 is provided with rollers 3, wherein there are connecting rods 4 arranged in pairs between the two door boxes 1, and the two connecting rods 4 interconnected, such as Figure 4 Shown, connecting rod 4 has a bending segment 5 near one end of door box 1, and its end is hinged in the box body. The bending section 5 and the connecting rod 4 can be integrally formed, or can be connected and formed by welding, bolting and other fixing methods.

[0021] The connecting rod 4 is distributed up and down on the door body 2, and the bending section 5 of the connecting rod 4 on the upper part is bent upwards, otherwise it is bent downwards.

[0022] The angle between the ...

Abstract

The invention relates to a retractable door, which comprises door boxes and a retractable door body consists of connecting rods, wherein the bottom portions of the door boxes are provided with rollers, connecting rods which are arranged in pair are arranged between the two door boxes, the two connecting rods are hinged each other, one end of the connecting rods closing to the door boxes is provided with bending segments, and the end portions of the bending segments are hinged in box bodies. The retractable door has the advantages that: firstly, the connecting rods are arranged symmetrically, thereby being uniform in force, and being reliable in driving. Secondly, the connecting rods can be completely taken to the inner portions of the door boxes, thereby leading the whole retractable door product to be simple and beautiful in appearance. Thirdly, a net-shaped expansion bracket is arranged on the connecting rods, thereby being not affected by structure and equipment precision. Fourthly, a traditional slider is not needed. Fifthly, the retractable door has the structural advantages of less panel points, high reliability and long service life.

Description

technical field [0001] The invention relates to a retractable door. Background technique [0002] The traditional telescopic door is composed of a door frame and a horizontal or vertical four-link telescopic frame installed in the door frame, and a slider is set on the main material of the door frame, so that the parallel four-rod telescopic frame can expand and contract in the horizontal direction to realize the door. Telescoping is on or off. [0003] Traditional retractable doors have complex procedures and cumbersome assembly processes, which cannot be assembled in unit modules. The products are basically assembled and connected by the factory, and the whole product is packaged and transported. The packaging is large in size, poor in economy, and high in cost. In addition, the four-link telescopic frame used in traditional products has many nodes, requires high dimensional accuracy, and its manufacturing cost is high. In addition, due to insurmountable assembly errors, ...
