Description

Technical Field

[0001] The invention relates to the field of tent construction, in particular to a tarpaulin reverse laying system. Background Art

[0002] Tarpaulin (or waterproof fabric) is a high-strength, highly flexible, and waterproof material. It is commonly made of canvas (oil canvas), polyurethane-coated polyester, or polyethylene plastic. Tarpaulins typically have sturdy grommets at the corners or edges for easy threading of ropes for lashing, hanging, or covering. Tarpaulins are generally categorized into two types: coarse tarpaulin and fine tarpaulin. Coarse tarpaulin, also known as tarpaulin, is a durable, fold-resistant fabric with excellent waterproof properties. It is used for automobile transport, covering open-air warehouses, and setting up tents in the field. Fine tarpaulin, with its warp and weft yarns, is used to make labor protection clothing and supplies. After dyeing, it can also be used as fabric for shoes, travel bags, backpacks, and other items. There are also rubber tarpaulins, shielding tarpaulins for fire and radiation protection, and tarpaulins for papermaking machines.

[0003] The original method of applying the tent roof cloth is mostly done on the outside of the tent. When there are obstacles in front and behind the site, such as buildings, light poles, etc., the vehicles or workers pulling the cloth have no working surface, making it very difficult to apply the cloth. Therefore, we proposed a reverse tarpaulin applying system for further improvement. Summary of the Invention

The second top mechanism and the third top mechanism have the same specifications as the components of the first top mechanism. The bottom of the tarpaulin support rod in the second top mechanism is fixedly connected to the top of the tarpaulin support rod in the first top mechanism and is arranged in a one-to-one correspondence. The bottom of the tarpaulin support rod in the third top mechanism is fixedly connected to the top of the tarpaulin support rod in the second top mechanism and is arranged in a one-to-one correspondence.
