Rotary type screen mechanism of electric telescopic door

Abstract

The invention relates to a rotary type screen mechanism of an electric telescopic door, which comprises a door row (100), a crossed connecting rod (11), a lower beam (12), a middle transverse rod (15) and an upper transverse rod (13), wherein the door row (100) comprises a plurality of doorframes (10); the crossed connecting rod (11) connects all the doorframes; the lower beam (12) is arranged at the bottoms of the doorframes; the middle transverse rod (15) is arranged in the middles of the doorframes; the upper transverse rod (13) is arranged at the upper parts of the doorframes and can do up-and-down motion; a screen assembly (20) which can rotate along with the stretching of the telescopic door is installed in each doorframe (10); and the upper end and the lower end of the screen assembly (20) are movably connected with an upper frame (14) of each doorframe (10) and the lower beam (12) respectively, and the screen assembly (20) is movably connected with the upper transverse rod (13) by a rotary connecting element (30). The rotary type screen mechanism can automatically rotate along with expansion or contraction of the telescopic door just by drive of the crossed connecting rod and the upper transverse rod of the telescopic door without single power drive, and the unification of practicability, decoration and aesthetic enjoyment of the electric telescopic door is realized.

Description

【Technical field】

[0001] The invention relates to a telescopic door, in particular to a rotary screen mechanism for an electric telescopic door that is driven by the telescopic door to rotate the screen. 【Background technique】

[0002] In recent years, as a new type of door, the electric telescopic door has been widely used because of its advantages of convenient opening, beautiful appearance, and electric control. The basic structure of the existing electric telescopic door includes a machine head part and a telescopic door part connected thereto, wherein the telescopic door part is formed by hinges of a plurality of door frames through upper and lower cross-type connecting rods and their cross bars. Though telescopic door can realize the telescopic opening and closing function of base door now, the structure of most electric telescopic doors is comparatively monotonous, and decoration and appreciation are poor. When the retractable door is opened and closed, only the para...
