Description

Technical Field

[0001] The utility model relates to the technical field of sunshade roofs, in particular to a retractable roof for building sunshade. Background Art

[0002] The awning has a comprehensive external shading function, which can completely block ultraviolet radiation and reduce the temperature at the bottom of the awning. In order to avoid affecting the brightness inside the building when not in use, most of the existing building awnings adopt a retractable structure.

[0003] At present, when the existing building sunshade roof is unfolded for use, dust, debris and other debris will inevitably fall on the top of the roof, and the existing sunshade roof does not have the function of cleaning the debris on the top of the roof when it is retracted. If the debris is not cleaned before it is rolled up, the debris will scratch the roof cloth, and the dust will also affect the service life of the roof cloth, which leads to certain shortcomings. In addition, the existing retractable building roof is exposed to the sun for a long time, and its roof cloth is very easy to break and damage, and then it needs to be replaced. The existing retractable roof is inconvenient to disassemble and replace. For this reason, we propose a retractable roof for building sunshade. Utility Model Content

[0012] 1. The retractable roof for building sunshade is coordinated by a servo motor, a bidirectional screw, a driving gear, a rotating shaft, a driven gear, a driving pulley, a mounting cover, a mounting shaft and a driven pulley. When the shed cloth is reeled in, the bidirectional screw and the driving gear can be driven to rotate by turning on the servo motor. The driving gear engages with the driven gear and drives the driving pulley to rotate. The driving pulley drives the driven pulley to rotate through the transmission belt. At the same time, the mounting shaft and the cleaning roller brush rotate to clean the debris on the top of the shed cloth, avoiding the situation where the debris scratches the shed cloth during reeling.

The retractable roof for building sunshade is coordinated by mounting blocks, connecting plates, mounting grooves, pull grooves, slide bars, slide plates, latches, sockets, springs and pull plates. When the winding roller and awning cloth need to be disassembled and replaced, it is only necessary to pull up the pull plate to drive the slide plate upward through the slide bar, and then pull the latch out of the socket to contact the limit of the connecting plate. Then the winding roller can be pulled out of the mounting groove through the connecting plate, and then the winding roller can be disassembled. Disassembly and installation are convenient and quick.
