Description

Technical Field

[0001] This utility model relates to the field of tarpaulin connection technology, specifically to a PVC tarpaulin that is easy to connect. Background Technology

[0002] PVC tarpaulins are made from high-strength canvas as the base fabric, coated with polyvinyl chloride (PVC) paste resin, and mixed with plasticizers, mildew inhibitors, antistatic agents, and other chemical additives, then plasticized at high temperatures. PVC tarpaulins are widely used in production and daily life, featuring lightweight, high strength, and long service life. In practical use, the dimensions of PVC tarpaulins are fixed. Therefore, when the dimensions are insufficient, PVC tarpaulins need to be spliced ​​to increase the usable area. Currently, common splicing methods for PVC tarpaulins include returning them to the factory for gluing and sewing. These splicing methods not only cause some damage to the surface of the PVC tarpaulin but also affect its performance, and the process is complex, impacting efficiency and waterproofing effectiveness. Utility Model Content

[0003] To address the problem of complex splicing processes for PVC tarpaulins in the aforementioned technologies, this utility model provides a PVC tarpaulin that is easy to connect.

[0004] The technical solution of this utility model is as follows: A conveniently connectable PVC tarpaulin includes: a tarpaulin body, A waterproof strip is arranged around the outer surface of the tarpaulin body, and multiple metal rings are arranged through the surface of the waterproof strip. The metal rings are evenly arranged on the surface of the waterproof strip in a single row or multiple rows. A fastener is provided through the metal collar, and a single fastener can penetrate two metal collars at the same time. The fastener has a connecting device fixedly disposed at one end away from the surface of the waterproof cloth strip, and the other end of the connecting device extends outward relative to the waterproof cloth strip to the side away from the tarpaulin body.

[0005] To achieve the fixing function of the connecting device, the connecting device is a waterproof hook and loop fastener, which is divided into male and female fasteners, and the male and female fasteners are respectively set on the outside of the waterproof strip and the tarpaulin body.

[0006] The method to ensure the connection stability of waterproof Velcro is that one end of the male buckle extends out of the outside of the waterproof fabric strip, and the extended part is used in conjunction with the female buckle.

[0007] To ensure the stability of the PVC tarpaulin connection, the fasteners include fastening bolts and nuts, and the length of the fastening bolts is not less than twice the thickness of the metal collar.

[0008] The method for connecting and fixing the multi-row metal collars is as follows: an extension plate is provided above one side of the multi-row metal collars, and the other side of the extension plate extends to the top of the metal collars near the tarpaulin body.

[0009] The fastening bolt and the extension plate are fixed together by the nut being located inside the extension plate, and the fastening bolt being fixedly connected to the nut inside the extension plate.

[0010] As a preferred technical solution, the fastening bolt and the nut are connected by a hanging rope.

[0011] To ensure stability when the extension plate is connected, the extension plate on the side closest to the tarpaulin body is fixed to the surface of the waterproof strip by cooperating with the fastening bolts.

[0012] To restrict the connection between adjacent tarpaulin bodies, the hanging rope is specifically configured such that when the fastening bolt and nut are connected, the middle part of the hanging rope wraps around the outside of the tarpaulin body and is located inside the connecting device.

[0013] The beneficial effects of this utility model are as follows: By setting waterproof strips around the outer side of the tarpaulin body, and multiple metal rings running through the outer surface of the waterproof strips, fasteners that cooperate with the metal rings are set inside the metal rings. In addition, the hanging ropes set between the fastening bolts and nuts in the fasteners can effectively restrict the connection method between adjacent tarpaulin bodies, thereby avoiding the complicated procedures in the traditional connection method. Furthermore, a connecting device is set on the outside of the waterproof strips to fix the shape after connection, thereby ensuring the waterproof effect of the tarpaulin after connection.

[0017] Example 1 like Figure 1-3 As shown in the figure, this embodiment demonstrates a PVC tarpaulin that is easy to connect, with the aim of solving the problem of damage to the surface of PVC tarpaulin caused by traditional gluing and sewing methods. The structure includes a tarpaulin body 1 and a waterproof strip 2 that is arranged around the outside of the tarpaulin body 1. The waterproof strip 2 is arranged around the upper and lower end faces of the tarpaulin body 1 by sewing. Multiple metal collars 3 are arranged through the surface of the waterproof strip 2. The multiple metal collars 3 are evenly distributed on the surface of the waterproof strip 2 in a single row or multiple rows. In this embodiment, the metal collars 3 on the outside of the tarpaulin body 1 to be connected are all arranged in a single row on the surface of the waterproof strip 2.

[0018] In order to achieve the connection between adjacent tarpaulin bodies 1, a fastener 4 is provided through the inside of the metal collar 3. The fastener 4 achieves the connection between adjacent tarpaulin bodies 1 by simultaneously passing through the metal collar 3 on the surfaces of two adjacent tarpaulin bodies 1. The fastener 4 includes a fastening bolt 401 and a nut 402. The length of the fastening bolt 401 is more than twice the depth of the metal collar 3.

[0019] Please refer to the appendix. Figure 1-3 A connecting device 5 is also provided on the outer surface of the waterproof strip 2. One end of the connecting device 5 is located away from the fastener 4, and the other end extends a certain length outward from the edge of the waterproof strip 2, that is, the direction of extension is away from the tarpaulin body 1. One end of the extended connecting device 5 is connected to the middle of another tarpaulin body 1. In addition, the connecting device 5 located on the surface of the waterproof strip 2 is arranged to cover the fastener 4.

[0020] It is worth noting that the connecting device 5 in this embodiment is a waterproof hook and loop fastener. The waterproof hook and loop fastener is divided into a male fastener and a female fastener. The male fastener and the female fastener are respectively set on the two tarpaulin bodies 1. The male fastener is set on the outside of the waterproof strip 2 of one of the tarpaulin bodies 1, and the female fastener is set in the middle of the other tarpaulin body 1. The width of the male fastener is greater than the width of the female fastener. The male fastener extends a certain length to the position of the female fastener and is used in conjunction with the female fastener.

[0021] Please refer to the appendix. Figure 1-3 When using this device, overlap the waterproof strips 2 on one side of the two tarpaulin bodies 1 to be installed, align the metal collars 3 on one side of the overlapped waterproof strips 2, and connect the fastening bolts 401 through the aligned metal collars 3 and nuts 402.

[0022] Example 2 See attached document Figure 1-7 Similar to Embodiment 1, the connection and positional relationships between the tarpaulin body 1, waterproof strip 2, metal collar 3, connecting device 5, and fastener 4 are the same. The difference is that in this embodiment, the metal collar 3 of one of the tarpaulin bodies 1 is arranged in multiple rows on the surface of the waterproof strip 2, with two rows in total. Furthermore, to restrict the connection methods between adjacent tarpaulin bodies 1, the fastening bolt 401 and nut 402 are connected by a hanging rope 7. The hanging rope 7 restricts the connection methods between adjacent tarpaulin bodies 1; that is, the connection between the fastening bolt 401 and nut 402 via the hanging rope 7 can only achieve a unique connection between adjacent tarpaulin bodies 1. It is worth noting that in this embodiment, an extension plate 6 is provided on the surface of the two rows of metal collars 3. The extension plate 6 is specifically located at the tail of the fastening bolt 401. The extension direction of the extension plate 6 is the direction of the tarpaulin body 1, and the extended portion extends to above the metal collars 3 near the inner side of the tarpaulin body 1. In addition, the nut 402 is located inside the extension plate 6, and the fastening bolt 401 passes through the metal collars 3 and cooperates with the nut 402 inside the extension plate 6. In order to limit the connection method between adjacent tarpaulin bodies 1, thereby avoiding the complicated procedures in the traditional connection method, a hanging rope 7 is provided between the fastening bolt 401 and the nut 402. The middle of the hanging rope 7 passes around the edges of the two connected tarpaulin bodies 1 and is located inside the connecting device 5. In addition, the extension plate 6 near the inner side of the tarpaulin body 1 is fixed to the waterproof strip 2 by the fastening bolt 401.
