Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a tarpaulin windproof clamp. Background Technology

[0002] Most commercially available tarpaulin windproof clamps are V-shaped, and they mostly increase the contact area between the tarpaulin and the clamp by using fixing teeth on the inside of the clamp. However, due to the limitations of the V-shaped design, it is difficult to distribute the fixing teeth evenly over a large area on the inside of the clamp, which limits the clamping force of traditional tarpaulin windproof clamps and reduces the windproof performance of the tarpaulin. In response to the above situation, we will carry out technical innovation based on the existing tarpaulin windproof clamps. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3A tarpaulin windproof clamp includes a concave frame 11. A clamping plate 12 is placed on the top of the inner wall of the concave frame 11. Fixing posts 17 are evenly fixed to the bottom of the clamping plate 12. Second fixing teeth 14 are evenly fixed to the left side of the bottom of the clamping plate 12, and fourth fixing teeth 16 are evenly fixed to the right side of the bottom of the clamping plate 12. Fixing holes 18 are evenly penetrated through the bottom of the inner wall of the concave frame 11. First fixing teeth 13 are evenly fixed to the left side of the bottom of the inner wall of the concave frame 11, and third fixing teeth 15 are evenly fixed to the right side of the bottom of the inner wall of the concave frame 11. The second fixing teeth 14 correspond to the first fixing teeth 13, the fixing posts 17 correspond to the fixing holes 18, and the fourth fixing teeth 16 correspond to the third fixing teeth 15. The top of the clamping plate 12 is evenly... There are two sets of hand-tightening bolts 19, with an anti-loosening component placed between them. Two sets of threaded holes are evenly distributed through the top of the concave frame 11. Two sets of grooves are evenly distributed on the top of the clamping plate 12, with annular limiting grooves on the inner walls of the grooves. A convex sliding groove is evenly distributed on the left side of the inner wall of the concave frame 11. The hand-tightening bolts 19 are screwed into the threaded holes. A limiting ring 21 is fixedly installed on the outer ring of each hand-tightening bolt 19. The bottom of each hand-tightening bolt 19 is rotatably positioned within the groove, and the limiting ring 21 is rotatably positioned within the annular limiting groove. The tarpaulin is inserted into the concave frame 11 and positioned below the clamping plate 12. Simultaneously rotating the two sets of hand-tightening bolts 19 moves the clamping plate 12 downwards, causing the second fixing tooth 14, fixing post 17, and fourth fixing tooth 16 to move downwards. As the tarpaulin moves downward, the tarpaulin below the fixing post 17 will be pushed into the fixing hole 18 by the fixing post 17. The tarpaulin below the second fixing tooth 14 and the fourth fixing tooth 16 will be clamped and bitten on the first fixing tooth 13 and the third fixing tooth 15 as the second fixing tooth 14 and the fourth fixing tooth 16 move downward. The left side of the clamping plate 12 is uniformly fixed with convex blocks 22, which are slidably disposed in the convex groove. The convex blocks 22 assist the clamping plate 12 to move up and down stably. The anti-loosening component includes a mounting frame 2. A set of storage slots is provided on both the left and right sides of the mounting frame 2. A sliding groove is opened through the top of the storage slot. A slider 23 is slidably disposed in the storage slot. A slider 23 is fixedly disposed on the opposite side of the two sets of sliders 23. A spring 26 and a slider 23 are fixedly mounted on top of each other. A lever 24 is fixedly mounted on the top of each slider 23. The spring 26 is fixedly mounted in the storage groove, and the lever 24 is slidably mounted in the groove. Anti-slip pads 25 are fixedly mounted on opposite sides of each slider 23. The mounting bracket 2 is fixedly mounted on the top of the concave bracket 11. The hand-tightening bolt 19 is located outside the anti-slip pad 25. By moving the lever 24 inward, the slider 23 and anti-slip pad 25 are moved inward away from the hand-tightening bolt 19, allowing the hand-tightening bolt 19 to be rotated. When the hand-tightening bolt 19 is tightened, its head is located outside the anti-slip pad 25. At this point, the lever 24 is released, and the spring 26's rebound force causes the slider 23 to tightly engage with the anti-slip pad 25 and the head of the hand-tightening bolt 19, thus locking the hand-tightening bolt 19.A fixing lug 1 is fixedly provided on the left side of the concave frame 11. After the tarpaulin is fixed inside the concave frame 11, the fixing lug 1 is attached to the pull rope on the outer fixing cone, thus completing the fixation of the tarpaulin.

[0019] Working principle: Insert the tarpaulin into the concave frame 11, positioning it below the clamping plate 12. Move the lever 24 inward, causing the slider 23 and anti-slip pad 25 to move inward away from the hand-tightening bolt 19. Then, rotate the hand-tightening bolt 19. By simultaneously rotating both sets of hand-tightening bolts 19, the clamping plate 12 moves downward. The clamping plate 12 then moves the second fixing tooth 14, the fixing post 17, and the fourth fixing tooth 16 downward. At this time, the tarpaulin located below the fixing post 17 will be pushed into the fixing hole 18 as the fixing post 17 moves downward. The tarpaulin located below the second fixing tooth 14 and the fourth fixing tooth 16... As the second fixing tooth 14 and the fourth fixing tooth 16 move down, the tarpaulin is clamped and bitten onto the first fixing tooth 13 and the third fixing tooth 15. When the hand-tightening bolt 19 is tightened, the screw head of the hand-tightening bolt 19 is located outside the anti-slip pad 25. At this time, the lever 24 is released, and the spring 26 uses the rebound force to drive the anti-slip pad 25 to fit tightly with the screw head of the hand-tightening bolt 19 through the slider 23, thereby locking the hand-tightening bolt 19. The left side of the concave frame 11 is fixedly provided with a fixing ear 1. After the tarpaulin is fixed inside the concave frame 11, the fixing ear 1 is tied to the pull rope on the outer fixing cone, thus completing the fixing of the tarpaulin.
