Abstract

A scissors telescopic venetian sunshade mainly relates to a sunshade device for residential buildings and office buildings. The utility model patent is that more than two groups of sunshade deflector groups are installed on the scissor telescopic mechanism. Each sunshade deflector group includes a sunshade deflector 2, a connecting shaft 6, and a slider 7; the scissor telescopic mechanism is composed of a scissor link chain installed on both sides of the frame 5; More than one set of scissor linkages; by adjusting the lift of the scissor telescopic mechanism, the linkage drives each set of sunshade deflectors 2 to expand and retract evenly at intervals, so as to achieve the purpose of sunshade, ventilation, and light adjustment. Because the sunshade deflector group and the guide rail 3 are slidingly connected, the structural strength is relatively high, and the window opening and sunshade are both correct, which improves the ability to resist natural wind disturbance.

Description

Scissor retractable venetian sunshades

Technical field:

The utility model patent relates to a sunshade curtain device for residential buildings and office buildings. In particular, it relates to a scissor telescopic venetian sunshade device. Used in the field of construction, it has the functions of shading, ventilation, adjusting indoor light, etc., and has better resistance to natural wind disturbance. It is also an ideal method to block radiant heat.

Background technique:

At present, the ventilation and shading measures we can take for residential and office buildings are to install indoor blackout curtains, rope-controlled venetian blinds or essential blinds, etc. Due to the influence of natural wind disturbance, the first two types need to close the windows during use and 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. Wooden shutters have certain limitations on the adjustment of sight and light.

Utility model content:

The utility model patent is that more than two groups of sunshade deflector groups are installed on the scissor telescopic mechanism. Each sunshade deflector group includes a sunshade deflector 2, a connecting shaft 6 and a slider 7; the sunshade deflector 2 and the connecting shaft 6 are connected as a rotatable movable connection; the connecting shaft 6 and the slider 7 are fixedly connected; The scissor telescopic mechanism is composed of scissor link chains installed on both sides of the frame 5; the scissor link chain is composed of two or more scissor link groups; The fork connecting rod 1 is formed; each group of scissor connecting rods is connected with the upper and lower groups of scissor connecting rods 1 through pins 4 to form a rotatable and movable connection; the connecting shafts 6 on both sides of each group of sunshade deflector groups are The intersection of the corresponding scissor linkages on both sides is connected as a rotatable movable connection; the frame 5 and the guide rail 3 are fixedly connected; the slider 7 and the guide rail 3 are connected as a non-rotatable movable connection; by adjusting the scissors, the telescopic The lifting and lowering of the mechanism drive each group of sunshade deflectors 2 to expand and retract evenly at intervals, so as to achieve the purposes of sunshade, ventilation and light adjustment. Because the sunshade deflector group and the guide rail 3 are slidingly connected, the structural strength is relatively high, and the window opening and sunshade are both correct, which improves the ability to resist natural wind disturbance.

Accompanying drawing 2 is the front structural schematic diagram of the utility model patent.

Accompanying drawing 3 is the side view structure diagram of "expanding" and "retracting" the sunshade deflector of the utility model patent.

The marks in the accompanying drawings are described as follows: 1-scissor link; 2-sunshade deflector; 3-guide rail; 4-pin; 5-frame; 6-connecting shaft;

Detailed ways:

The utility model patent is that more than two sets of sunshade deflector groups are installed on the scissor telescopic mechanism; each group of sunshade deflector groups is composed of sunshade deflector 2, connecting shaft 6 and slider 7; It is connected with the connecting shaft 6 as a rotatable movable connection (the angle control mechanism of the sunshade deflector 2 is omitted); the connecting shaft 6 and the slider 7 are fixedly connected; the slider 7 and the guide rail 3 are connected as a non-rotatable sliding connection; the guide rail 3 and the frame 5 are fixedly connected; the scissors telescopic mechanism is composed of a scissor link chain installed on both sides of the frame 5; the scissor link chain is composed of two or more scissor link groups; each group of scissor link The group is composed of two scissor connecting rods 1 placed crosswise; each group of scissor connecting rods is connected to the upper and lower groups of scissor connecting rods 1 through pins 4 to form a rotatable and movable connection; each group of sunshade diversion The connecting shafts 6 on both sides of the plate group are respectively connected to the intersections of the scissor linkage groups on both sides as rotatable and movable connections; the sliders 7 on both sides of the top sunshade deflector group are fixedly connected to the frame 5; The lifting of the mechanism (the lifting control mechanism is omitted) is linked to drive each group of sunshade deflectors 2 to expand and retract evenly at intervals, thereby achieving the purposes of sunshade, ventilation, and light adjustment.

Due to the adoption of the scissor telescopic mechanism, the utility model patent has a larger and uniform ventilation interval, and has a stronger ability to resist natural wind disturbance.
