Description

Technical Field

[0001] The utility model relates to the technical field of building material protection, in particular to a retractable building material rain shelter. Background Art

[0002] During construction, when building materials are brought into the site, they are generally stored in designated areas, most of which are open-air. The work teams often forget to cover the tarpaulins after the building materials are brought into the site. When it rains, even if the tarpaulins are covered, the rainwater flows along the ground and can easily wet the building materials at the bottom. The work teams usually use bricks and other sharp and hard objects to press down the tarpaulins, increasing the risk of damage to the tarpaulins.

[0003] After searching, a Chinese patent with publication number CN211081232U discloses a building material awning, which includes at least two pallets, a protective mat and a waterproof cloth. Support feet are installed on the lower surface of the pallet, and safety hooks are installed on the side of the pallet. Buckles are distributed on the edge of the waterproof cloth, and the safety hooks can be hung on the buckles. When the building material awning is in an assembled state, the building materials are placed on at least two pallets, the protective mat covers the protruding edges of the building materials, the waterproof cloth covers the protective mat, and the buckles of the waterproof cloth are connected to the safety hooks.

[0004] The device provides a building material rain shelter which is simple in structure, convenient in use, economical and practical.

[0005] Combining the prior art and the device, it is found that:

[0010] In some embodiments, a counterweight base is fixed to the lower side of each of the plurality of limiting rings.

[0011] In some embodiments, a connecting rod is fixedly connected between two vertically adjacent moving blocks.

[0012] In some embodiments, the awning cloth is made of polypropylene.

[0013] In some embodiments, the plurality of counterweight bases are specifically cast iron blocks.

[0014] Compared with the prior art, the present invention has the following significant advantages:

[0015] First, the utility model pulls multiple vertical rods to drive multiple moving blocks to slide along the outer sides of multiple guide rods respectively, and at the same time, the two upper telescopic arms and the lower telescopic arms rotate, and the awning cloth can be unfolded according to the parallelogram folding principle, which is easy to operate;
