Abstract

The utility model relates to a venetian sunshade with multi-rotation roller blind rope linkage transmission type, which is mainly used in dimming, ventilation and sunshade of residences and office buildings. It consists of a linkage transmission cable (5), a linkage rod (6), a frame (7) and more than two sets of rotary shutter units; each set of units includes: a rotary spring (1); a rotary shutter shaft (2); a sunshade ( 3); the sunshade cloth connecting rod (4); by adjusting the height of the linkage transmission cable (5), the control of indoor sunshade, ventilation and light transmission is realized. When sunlight is needed, the lifting of the linkage transmission cable (5) drives each group of sunshade cloths to move upwards, so that all the sunshade cloths are retracted in the shape of a "guardrail", which has a certain effect of a guardrail. When sunshade is needed, adjust the linkage transmission cable (5) to lower it, and each group of sunshade cloths moves downwards, so that the sunshade cloths are unfolded in a "louver" shape.

Description

Multi-turn roller blind rope linkage transmission type venetian sunshade

Technical field:

The utility model patent relates to a sunshade curtain and protective fence device for residential buildings and office buildings. In particular, it relates to a venetian sunshade device which is linked and driven by multi-rotation roller blind ropes. It is used in the field of construction, which has the functions of sunshade, ventilation, and adjustable light intensity. It is an ideal method to block radiant heat.

Background technique:

At present, the sun-shading measures we can take for residential buildings and office buildings are sun-shading curtains installed indoors, which cannot be ventilated. While shading, indoor ventilation and light are also restricted. Especially in the summer in the southern region, the heat insulation effect is not ideal.

Utility model content:

In order to improve the current situation, I have specially designed the outdoor sunshade. The utility model patent has solved above many problems. The utility model patent is to wrap multiple sections of sunshade cloth on the corresponding rotary roller blind shaft respectively, one end of the sunshade cloth is fixedly connected to the rotary roller blind shaft, the other end is connected to the connecting rod of the sunshade cloth, and the linkage transmission cable is respectively connected to each unit The sunshade cloth connecting rod is connected; by adjusting the height of the linkage transmission cable, the control of indoor sunshade, ventilation and light transmission is realized. When sunlight is needed, the linkage transmission cable is adjusted upwards, and the linkage drives each group of sunshade cloths to move upwards, so that all the sunshade cloths are retracted, forming a "protective fence" shape, strong wind resistance, and has a certain protective fence effect. When shading is required, the linkage transmission cable is adjusted downwards, and the linkage drives each group of sunshade cloths to move downwards, and the sunshade cloths are unfolded in the shape of "louvers". While shading and dimming, the airflow can flow through the gaps between the sunshade cloths.

Description of drawings:

Accompanying drawing 1 is the structure schematic diagram of a multi-rotation roller blind rope linkage transmission type venetian sunshade of the utility model patent.

Accompanying drawing 2 is the side view structure schematic diagram of "expanding" and "retracting" of the sunshade cloth of the utility model patent.

The marks in the accompanying drawings are described as follows: 1-revolving spring; 2-revolving roller shade shaft; 3-shading cloth; 4-shading cloth connecting rod;

Detailed ways:

Revolving roller blind: when there is no external force, the sunshade cloth (3) is attached to the revolving roller blind shaft (2) by the rotating force of the revolving spring (1) in a "roll" shape. A roller blind in which the sunshade cloth is unfolded by external force.

The utility model patent is made up of linkage transmission cable (5), linkage rod (6), frame (7) and multiple groups of rotary roller shutter units (the illustration is five groups, which can be increased or decreased according to the situation.). Each group of units includes: rotary spring (1); rotary roller shade shaft (2); sunshade cloth (3); 7), the other end is fixed on the rotary roller shade shaft (2); the two ends of the rotary roller shade shaft (2) are connected to the both sides of the frame (7) as a rotatable movable connection; the two sides of the sunshade cloth (3) They are respectively connected with the rotary roller shade shaft (2) and the sunshade cloth connecting rod (4); the two ends of the sunshade cloth connecting rod (4) are respectively connected with the linkage transmission cables (5) on both sides; the linkage transmission cables (5) on both sides ) is connected to the linkage rod (6); when the linkage rod (6) is adjusted upwards, relying on the resilience of the revolving spring (1) in each group of revolving roller shutter units, through the upward linkage transmission of the linkage transmission cable (5), the Each group of sunshade cloth connecting rods (4) drives the corresponding sunshade cloth (3) to roll back on the roller shade shaft (2); Transmission, so that the sunshade connecting rods (4) of each group of rotary roller blind units drive the corresponding sunshade cloth (3) to unfold; the linkage transmission of the linkage transmission cable (5) realizes the deployment and retraction of the sunshade cloth of all the rotary roller blind units control.

When there is no need for shading, adjust the linkage transmission cable (5) upwards, and the linkage drives the sunshade cloth (3) of each group of rotary roller blind units to roll back on the roller shade shaft (2), and the whole is in the shape of a "protective fence". At this time, the sunshade area The smallest, the smallest wind resistance, strong wind resistance, the largest lighting area, and can play a certain role in the protective fence.

When sunshade is needed, the linkage rope (5) is adjusted downward, and the sunshade cloth (3) of each group of rotary roller blind units is jointly driven to unfold, and the whole is in the shape of a "louver", realizing the purpose of sunshade and dimming.

Considering the influence of outdoor airflow disturbance, the utility model patent adopts the linkage form of multiple rotary roller blinds, which is designed in the shape of "louver", which effectively reduces the influence of airflow disturbance, has better wind resistance, and is more practical .
