Problems solved by technology

This kind of traditional louver structure generally can only be switched between two states, and it cannot realize the function of sunshade and ventilation effect at the same time.
In addition, these existing sunshade devices only adopt the mode of blocking, so the function of preventing ultraviolet radiation is relatively poor.

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the specific embodiments and drawings.

[0020] In specific implementation, such as Figure 1-4 As shown, a sunshade device includes a long strip-shaped support 1 arranged horizontally above, on which a number of hanging parts 2 can be horizontally slidably mounted, and each hanging part 2 is correspondingly provided with a piece of rectangular The blade 3, the middle part of the upper end of the blade 3 is rotatably suspended on the corresponding hanger 2 by the rope 4 and is in a lateral posture when the initial state without external force is maintained. The blades are divided into two groups of left and right symmetry. The outer sides of adjacent blades are all connected by lines 5 of fixed length, the length of which is equal to or less than the width of the blades, wherein the blades at both ends of the support 1 are respectively fixed relative to the support 1 (in this embodiment,...

Abstract

The invention discloses a sun shading device, comprising a strip-shaped support which is horizontally arranged above a blade folding and unfolding device and a blade angle regulating device, wherein a plurality of hanging parts are hung on the support in a horizontally sliding manner, a rectangular blade is correspondingly arranged below each hanging part, the middle part of the upper end of each blade can be rotatably suspended on a corresponding hanging part by virtue of a rope and keeps at an edge-on posture which is an initial state under no action of an external force, the blades are divided into a left group and a right group which are in bilateral symmetry, the outer sides of adjacent blades in each blade group are connected by virtue of lines with fixed length, length of each line is equal to or less than width of the blades, and the blades which are arranged at the two ends of the support are respectively fixedly arranged relative to the support. The sun protection device disclosed by the invention has the advantages that structure is simple, control is convenient and sun shading effect and ventilation effect are both realized by adjusting a shelter according to irradiation direction of the sun; and the sun shading device disclosed by the invention has the effects of preventing electromagnetic wave radiation, insulating heat and shielding ultraviolet rays.

Description

technical field [0001] The invention relates to a sunshade device, in particular to a sunshade device which is especially suitable for use on windows. Background technique [0002] At present, in houses located in hot areas, when the windows of the house are facing east and west, in order to avoid sunlight, it is generally necessary to install sunshade devices on the windows. [0003] Existing sunshade devices generally include two types, one is a roller shutter structure, that is, a roller shutter mechanism is used to roll up the sunshade cloth, which does not affect the normal use of the window at ordinary times, and the sunshade cloth is pulled out and put down when the sunshade is needed. shade. This kind of roller shutter structure is difficult to realize the ventilation function when shading. In addition, there is a louver structure, which can be adjusted to a horizontal state for ventilation when there is no need for shading, and can be adjusted to a closed state fo...
