Worm and gear speed reducer of sun louver

Abstract

In order to solve the problems that in the prior art, due to structure space limiting, the transmission strength is not sufficient, an opening structure has the running dead point, and opening controlcannot meet the expected effects and needs, the invention provides a worm and gear speed reducer of a sun louver. The worm and gear speed reducer comprises a speed reducer shell with a shaft hole, aworm gear arranged in the shell and a worm arranged in the shaft hole in a sliding and penetrating manner, a traditional structure that a motor drives a push head, the push head drives a connecting rod, and the connecting rod drives an L-shaped connecting rod on one side of a shutter is not adopted, a transmission motor is connected with the worm and gear speed reducer through connection of a transmission converter and a transmission shaft, the worm and gear speed reducer drives shuttle-shaped blades to rotate to move, the structure is simple, and the speed reducer is suitable for any square pipe structure space.

Description

technical field [0001] The present invention relates to the technical field of external wall louver equipment, and more specifically, relates to a worm gear reducer for sun visors. Background technique [0002] As a functional product of modern buildings, exterior wall shutters have been widely used in modern buildings. Their main advantages are as follows: 1. Sunshade: By adjusting the opening angle of the shutters, it can reflect the light intensity and effectively resist the strong outdoor sunlight, ultraviolet radiation and heat. 2. Ventilation: By adjusting the opening angle of the louver blades, the air flow rate can be increased or decreased to achieve artificial control of the fresh air flow; 3. Firefighting and smoke exhaust: for In the case of fire, smoke, poisonous gas and other hazards to human safety in confined places, the shutters and fire control system are networked and linked to automatically open the shutter blades to remove harmful gases and reduce disast...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the existing problem that the transmission force is insufficient due to the limitation of the structural space, and there are running dead points in the opening structure, and the opening control cannot reach the expected effect and requirements, the present invention proposes a worm gear reducer for the sun visor, which does not The traditional motor drives the push head, the push head drives the connecting rod, and the connecting rod drives the L-shaped connecting rod on one side of the louver. Instead, the transmission motor is connected to the transmission shaft through the transmission converter and connected to the worm gear reducer, which is decelerated by the worm gear. The device drives the shuttle-shaped blade to rotate. This structure is simple and suitable for any square tube structure space.
