Technical Field
[0001] This utility model belongs to the field of plastic tarpaulin unfolding technology, specifically a plastic tarpaulin that is easy to unfold quickly. Background Technology
[0002] Plastic tarpaulins are a common type of tarpaulin, usually made of plastic materials such as polyvinyl chloride and polyethylene. The plastic material itself has good waterproof properties, which can effectively block rainwater and snow water, protecting the items covered by the tarpaulin from moisture. It has high strength and toughness, is not easy to tear or wear, and can withstand a certain amount of external force pulling and friction, and has a relatively long service life. However, plastic tarpaulins do not have hook-and-loop components at the corners, and it requires multiple people to work together to set them up.
[0003] Existing plastic tarpaulins need to be unfolded and laid on top of items during use. However, unfolding a folded plastic tarpaulin requires multiple people to work together to unfold it and lay it on top of the items, which is quite cumbersome. In addition, the corners of the unfolded plastic tarpaulin lack positioning structures, resulting in poor positioning stability after the plastic tarpaulin is unfolded.
[0004] Therefore, a plastic tarpaulin that is easy to quickly unfold is proposed to address the above problems. Utility Model Content
[0005] To address the problems mentioned in the background art, this utility model provides a plastic tarpaulin that is easy to quickly unfold. It has a hanging unfolding structure, which allows one person to directly swing open the plastic tarpaulin from one of the corners, thus enabling the plastic tarpaulin to be quickly unfolded.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic tarpaulin that is easy to quickly unfold, comprising a plastic tarpaulin body, wherein corner buckles are fixedly provided at both corners of the plastic tarpaulin body, and the outer side of the corner buckles also includes...
[0007] The hanging assembly is spread out, and a positioning lock is fixedly installed on the outer side of the spreading and hanging assembly. A positioning frame is sleeved on the outer side of the positioning lock. A rotating buckle is rotatably installed inside the positioning frame. A sliding plate is slidably installed inside the rotating buckle. A positioning sleeve is fixedly installed at the other end of the sliding plate. A counterweight strip is fixedly installed at the edge of the plastic tarpaulin body. A fabric strap is fixedly installed on the outer side of the counterweight strip.
[0008] Preferably, the positioning frame has a slot on the side near the corner buckle, and the positioning lock passes through the slot and fits against the positioning frame.
[0009] Preferably, the slot is a circular horizontal groove, and the shape of the positioning latch is the same as that of the slot.
[0010] Preferably, the rotating buckle has grooves on both the front and rear sides, and the sliding plate is slidably disposed inside the grooves.
[0011] Preferably, a damping rod is fixedly disposed inside the sliding plate and fixedly disposed with the rotating buckle, and a spring is sleeved on the outside of the damping rod and fixedly disposed with the rotating buckle.
[0012] Preferably, both ends of the counterweight bar are provided with insert shafts that are inserted into the plastic tarpaulin body.
[0013] Preferably, the fabric pull strap is made of plastic fabric, and the surface of the fabric pull strap has double round holes.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model, through the structural design of the openable hanging component, can position the corners of the plastic tarpaulin through a multi-directional hanging structure, or have workers directly pull the counterweight strip, or tighten the cloth strip strap for positioning, and directly swing the remaining plastic tarpaulin open, so that the plastic tarpaulin can be quickly unfolded and laid on the surface of the item.
[0016] 2. This utility model, through a slidable guide rotating buckle structure and spring design, allows the spring to tighten the sliding plate structure, which can slide inside the rotating buckle, thereby controlling the sliding plate structure to remain stable when the plastic tarpaulin is unfolded.

[0024] 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.
[0025] The following describes an embodiment of this utility model based on its overall structure.
[0026] like Figures 1 to 4 As shown, this utility model provides a plastic tarpaulin that is easy to quickly unfold, including a plastic tarpaulin body 1. Corner buckles 2 are fixedly provided at both corners of the plastic tarpaulin body 1. The corner buckle 2 structure design can improve the stability of the plastic tarpaulin body 1. The outer side of the corner buckle 2 also includes...
[0027] The hanging assembly 3 is spread out, and a positioning lock 33 is fixedly installed on the outside of the hanging assembly 3. A positioning frame 32 is sleeved on the outside of the positioning lock 33. A rotating buckle 31 is rotatably installed inside the positioning frame 32. A sliding plate 35 is slidably installed inside the rotating buckle 31. A positioning sleeve 39 is fixedly installed at the other end of the sliding plate 35. A counterweight strip 4 is fixedly installed at the edge of the plastic tarpaulin body 1. The counterweight strip 4 structure increases the counterweight and facilitates unfolding. A fabric strap 6 is fixedly installed on the outside of the counterweight strip 4. The added fabric strap 6 structure is designed to facilitate positioning of the edge of the plastic tarpaulin body 1.
[0028] In this embodiment, the positioning frame 32 has a slot 34 on the side near the corner buckle 2, and the positioning buckle 33 passes through the slot 34 and fits against the positioning frame 32. The slot 34 is a circular horizontal groove, and the shape of the positioning buckle 33 is the same as that of the slot 34. The positioning buckle 33 can pass through the slot 34 structure for rotational positioning. The front and rear sides of the rotating buckle 31 are provided with sliding grooves 36. The sliding plate 35 is slidably disposed inside the sliding groove 36. The sliding plate 35 is fixedly disposed inside the sliding plate 35 and fixedly disposed with the rotating buckle 31. The outer side of the damping rod 38 is sleeved with a spring 37 fixedly disposed with the rotating buckle 31. The spring 37 pushes the damping rod 38 to keep it in the unfolded state and prevents the sliding plate 35 from disengaging.
[0029] Both ends of the counterweight bar 4 have insert shafts 5 that are inserted into the plastic tarpaulin body 1. The fabric strap 6 is made of plastic fabric and has double round holes on its surface. The double round hole structure makes it easy to hang on the outside of the hook for positioning.
[0030] The working principle and process of a plastic tarpaulin that can be quickly and easily deployed:
[0031] When in use, the rolled-up plastic tarpaulin body 1 can be directly installed on the outside of the positioning lock 33 on the outside of the corner buckle 2 by installing the positioning frame 32 in the extension and hooking assembly 3. By rotating the positioning frame 32, the positioning plate structure on both sides of the positioning lock 33 can be clamped inside the positioning frame 32 through the slot 34 structure. After fixing the positioning frame 32, the plastic tarpaulin body 1 with the extension and hooking assembly 3 installed can be thrown forward. The rolled-up plastic tarpaulin body 1 can be pushed forward to unfold it. The corners can be pulled by one person. The unfolded plastic tarpaulin body 1 is flat and not easy to misalign. At the same time, the added sliding plate 35 structure can slide inside the rotating buckle 31. With the help of the spring 37 on the outside of the damping rod 38, it can be tightened to tension the plastic tarpaulin body 1. Alternatively, the positioning pin structure can be directly inserted into the double round hole of the cloth strip pull belt 6 to position the counterweight 4. The plastic tarpaulin body 1 can be unfolded directly. Multiple unfolding methods make the unfolding operation more convenient.
