An outer sunshade steering transmission device

Abstract

The invention relates to an external sunshade curtain steering transmission device. The device comprises a hanging loop and a transmission box which is arranged inside the hanging loop, wherein the hanging loop is connected with an external sunshade curtain installation auxiliary frame, and the hanging hoop comprises an n-shaped loop body and supporting rods connected to the two ends of the loop body; the transmission box comprises a box body, and a driving gear shaft connected with a driving shaft and a driven gear shaft connected with a driven shaft are arranged inside the box body; a gear of the driving gear shaft and a gear of the driven gear shaft are bevel gears and are meshed with each other; a certain angle is formed between the axis of the driving shaft and the axis of the driven shaft. The device is reasonable in design, simple in structure and convenient to install, and an external sunshade curtain is lifted more conveniently by changing the transmission direction; in addition, transmission uniformity is improved, noise is lowered, the service life is prolonged, and use comfort is enhanced.

Description

technical field [0001] The invention relates to a construction equipment transmission device, in particular to a transmission device for an external sunshade curtain of a building, in particular to a steering transmission device for an external sunshade curtain. Background technique [0002] At present, external shading of buildings has become one of the important measures for building energy saving. In the field of external shading of existing buildings, it is often encountered that the external windows of buildings with various geometric shapes protrude, that is, the external windows of a window opening may have multiple windows, and these windows are distributed in broken lines on the plane, and there are angles between them Therefore, it has become a commonly used technology to control the lifting of the outer sunshade by the transmission structure of the steering. At present, most of the universal joints are used to connect the drive shaft of the outer sunshade. Howeve...

AI Technical Summary

Problems solved by technology

At present, most of the universal joints are used to connect the drive shaft of the outer sunshade. However, the universal joints often have the following problems: (1) The universal joints are not only easily polluted when exposed to the air, but also the lubricating oil between the parts will be lost in a short time. Dry and not lubricating, resulting in large power transmission resistance and unsmooth transmission; (2) Due to its own transmission principle, the rotation speed of the universal joint is uneven during transmission; (3) One end of the universal joint is directly connected to the drive shaft during transmission. The other end is directly connected to the driven shaft, and there is no support point at both ends, and it is not convenient to set a support point at the middle section, that is, the torque of the corner transmission directly acts on the drive shaft at both ends, making the drive shaft prone to bending and associated vibration , noise, affecting the quality of living environment
