Abstract

The invention discloses an extension rolling door used for door control. The extension rolling door comprises a self-walking remote control power machine head, a door row mesh fence and a ground track, and is characterized in that the door row mesh fence comprises door posts, pile fixing posts and steel wire ropes, the door posts and the pile fixing posts are serially connected with one another bythe steel wire ropes to form single-row mesh fences, beads are serially connected onto the steel wire ropes to control mesh fence distances, one end of the door row mesh fence is connected with the power machine head, the other end of the door row mesh fence is connected with a power rewinding drum arranged at a fixed mounting location, the power machine head can walk when the extension rolling door runs, the power rewinding drum can rotate when the extension rolling door runs, accordingly, the door row mesh fence can be rewound and stretched on the rewinding drum, and the extension rolling door can have opening or closing functions. Compared with the prior art, the extension rolling door has the advantages that the extension rolling door is light in structure and low in manufacturing, transporting and running costs; the extension rolling door can stably run, is wind-resistant and anti-crawling and is easy to maintain; the extension rolling door is attractive and elegant and is high in sense of design.

Description

Technical field: [0001] The invention relates to a rolling door used as access control. Background technique [0002] At present, telescopic doors are generally provided at the entrances and exits of public places such as state organs and large units. Most of the telescopic doors in the prior art adopt configurations such as two-linkage, three-linkage or four-linkage oblique fences and horizontal net fences. Such telescopic doors all have the following defects: one is bulky, heavy, The cost of materials is high and transportation is difficult; second, the structure is complex and the processing cost is high; third, it occupies a large space; fourth, it is easily damaged and the maintenance cost is high; fifth, the appearance is not beautiful. Invention content: [0003] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide an access control extension with small volume, light weight, less material, easy transportat...
