Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tarpaulin fastening, more specifically, the utility model relates to a tarpaulin fastening device for the inner tarpaulin of a double-layer roof of a canopy. BACKGROUND

[0002] The double-layer roof of a canopy refers to a canopy design with a two-layer roof structure, which is usually used to provide better thermal insulation, heat insulation and waterproof performance. The design of the double-layer roof not only improves the practicality of the canopy, but also increases its aesthetic appearance, making the canopy look more high-end and atmospheric. In the prior art, the expansion method is to expand the screw after the fixed tube is fixed. Under the action of wind and rain and snow, it will become loose, forming a safety hazard.

[0003] After searching, the Chinese patent with the publication number CN214195799U discloses a tarpaulin clamping and fixing device. The rotation of the double-headed stud drives the sliding block to move along the double-headed stud axis direction. The entire scissor-type telescopic frame forms a rhombus. The two sliding blocks are the two endpoints of the vertical shaft. When the vertical shaft is shortened, the horizontal shaft is correspondingly lengthened, driving the long beam pipe sleeve to expand the long beam. The expansion method of this scheme has better expansion effect. The long beam pipe sleeve can clamp and fix the long beam, completing the horizontal fixation.

[0004] The above-mentioned fixing device, when in use, expands the long beam pipe sleeve by increasing the distance between the opposite horizontal shafts, thereby expanding the two vertical long beams, and finally expanding the tarpaulin. However, it is not convenient to control the tightness of the inner tarpaulin. Over-tightening or over-loosening may cause uneven stress distribution of the canopy structure, which may damage the canopy structure in the long run. UTILITY MODEL CONTENTS
