Abstract

The invention relates to a stretchable sunshade for a construction site. The stretchable sunshade comprises a power transmission device. The power transmission device is connected two screw rods. The screw rods are each sleeved with a sleeve. An internal thread on each sleeve is matched with a thread on a lead screw. One end of a connecting rod is fixedly connected to each sleeve, the other end of each connecting rod is fixedly provided with a movable block, a guiding rod is installed on each movable block, one end of the connecting rod I in a stretchable device is movably connected to the guiding rod, the connecting rod II in the stretchable device is movably connected to the movable block, and the other end of the connecting rod I is hinged to the connecting rod II. An awning cloth is installed on the stretchable device. The stretchable sunshade is stable in performance, low in cost, high in safety and wide in application range, and can be applied to a door head, a balcony, a window and other places.

Description

technical field [0001] The invention belongs to construction tools, and relates to a sunshade, in particular to a telescopic sunshade for a construction site. Background technique [0002] It can be put away in summer, and can be stretched out in rainy and snowy weather. There are soft and hard canopies. Soft sheds need steel structure support, such as plastic canopies, canvas sheds, etc.; hard sheds, such as glass sheds, wooden sheds, etc. These sheds are usually installed in a fixed way, and most of them cannot be folded, and a few of them can be folded, and it is difficult to open and fold them. Some sheds that are easy to open and retract have a small coverage area and weak pressure resistance, which cannot withstand strong winds, heavy rains and snow. [0003] For example, the invention patent of application publication number CN104563413, a kind of folding sunshade, is installed on the square courtyard wall and is used. It consists of a column, a cross bar, a plurali...
