Single-motor window shutter for large window

Abstract

A single-motor window shutter for a large window comprises a shutter box. An upper cover, a left end seat, a right end seat and a lower cover are connected by end screws to form the shutter box, a reel which is respectively rotationally connected with the left end seat and the right end seat is horizontally disposed on the shutter box, a tubular motor is arranged on the reel, a left guide track is vertically arranged at the lower end of the left end seat, a right guide track is vertically disposed at the lower end of the right end seat, two shutter hanging sheets are wound on the reel, a middle end seat is arranged in the middle of the shutter box, a through hole is disposed in the middle of the middle end seat, the reel penetrates through the through hole, and a middle guide track with double tracks is arranged at the lower end of the middle end seat. The single-motor window shutter for the large window has the advantages that production cost is sufficiently reduced while a mechanical performance is guaranteed and wind load resistance and an antitheft safety performance are improved, and failure rate of the electric window shutter is reduced; the problem that a gap is formed when a conventional window shutter is used and two shutter boxes of the conventional window shutter are spliced is avoided owing to the middle end seat, and sealing and heat-insulation performances are fine; and the shutter window is integrated, is more attractive and is installed more simply and easily.

Description

technical field [0001] The invention relates to the field of building doors and windows, in particular to a single-motor roller shutter window for large windows. Background technique [0002] At present, in the field of building doors and windows, for indoor lighting, windows are getting bigger and bigger. Large windows with an area of ​​more than 3 square meters are wider. In order to ensure mechanical strength, improve wind pressure resistance and anti-theft safety, two roller shutters are generally used. The boxes are arranged side by side, each roller shutter box is equipped with a reel and a motor on the reel, each reel is wound with a curtain piece, and each roller shutter box is equipped with two guide rails vertically at the lower end of both sides Among them, the two side-by-side guide rails in the middle are independent of each other, and some share a middle guide rail with double tracks, and a motor drives a curtain to open and close the window. The structure of ...

AI Technical Summary

Problems solved by technology

The structure of the above-mentioned rolling shutter window has the following disadvantages or deficiencies: the motor is the highest component of the entire rolling shutter window, the cost of the two motors is high, and the failure rate is also high, and the two adjacent end seats between the two rolling shutter boxes Due to the splicing, there are gaps, poor thermal insulation, and the perfect splicing of two independent roller blinds is very difficult
