[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] like Figures 1 to 3 As shown, this utility model discloses a sun-protective, heat-insulating, and easily connectable tarpaulin, including a tarpaulin body 1. The tarpaulin body 1 adopts a multi-layer composite structure, namely, an outer layer of silver coating or PU sun-protective coating, a middle layer of heat-insulating aluminum film interlayer, and an inner layer of breathable polyester base fabric, to achieve a comprehensive function of sun protection, heat insulation, and breathability. Horizontally symmetrical connecting units are provided at the transverse edges or symmetrically distributed positions of the tarpaulin body 1 for quickly connecting hook-shaped parts or other rod-shaped structures. The connecting unit includes multiple spaced connecting holes 101, each connecting hole 101 embedding a cable ring 2 made of wear-resistant nylon material. The cable ring 2 has a cable hole at its center, and multiple radially movable extrusion blocks 3 are evenly distributed around the circumference of the cable hole. The extrusion blocks 3 can move radially to extrude pressure on the inserted hook-shaped parts.

[0019] When the hook-shaped part of the hook is inserted into the cable hole, the compression block 3 is pressed outward by the surface of the hook-shaped part and, under the action of radial elastic restoring force, presses tightly against the hook surface, forming a multi-point friction locking. Specifically, the cable ring 2 includes a base 21, which is an annular structure with an axially penetrating through groove 211 inside. The outer side of the through groove 211 has a positioning groove 212 for accommodating the initial position of the compression block 3. When the compression block 3 is in the initial position, there needs to be a gap between the compression block 3 and the positioning groove 212 for the compression block 3 to slide. The retainer 22 is installed in the through groove 211 by adhesive. The side wall has multiple openings 221 that are radially aligned with the cable hole. The compression block 3 is embedded in the openings 221 and can slide along the direction of the openings 221. The outer side of the extrusion block 3 is the transmission end, and the inner side is the extrusion end. The center of the retainer 22 is provided with a connecting hole 222, which is connected to the opening 221 for the hook-shaped part to pass through. When the hook-shaped part of the hook passes through the connecting hole 222, the extrusion end is pressed against the surface of the hook-shaped part to apply radial force.

[0020] Furthermore, the outer side of the retainer 22 is provided with an annular groove 223, and an annular spring 4 is installed in the annular groove 223. The transmission end of the compression block 3 is provided with a notch 31, and the annular spring 4 is embedded in the notch 31. When the hook is inserted into the connecting hole 222, the compression end is squeezed and moves outward, the transmission end compresses the annular spring 4, and the restoring force of the annular spring 4 drives the compression block 3 to return inward, forming a dynamic friction lock, which effectively prevents the hook-shaped part of the hook from coming out of the cable hole. When it is necessary to remove the tarpaulin body 1, it is only necessary to pull the hook-shaped part so that the pulling force is greater than the friction force generated, and the hook-shaped part of the hook can be pulled out of the cable hole. In this way, the tarpaulin body 1 can be quickly disassembled and assembled by simply inserting and pulling, which improves the convenience of disassembling and assembling the tarpaulin body 1. It is effectively suitable for outdoor sunshades, temporary warehouses and other scenarios that require repeated disassembly and assembly of the tarpaulin body 1, and ensures the connection stability in strong wind environments. The multi-layer composite structure takes into account sun protection, heat insulation and durability.

[0021] In this embodiment, the mounting structure of the annular spring 4 includes a locking block 5 within the annular groove 223. The locking block 5 and the retainer 22 are integrally injection molded. The locking groove 51 on the locking block 5 is used to fix the annular spring 4 and prevent it from coming out. Furthermore, to facilitate the push of the extrusion block 3 outward when the hook-shaped part is inserted into the cable hole, arc-shaped sidewalls 32 are provided on the upper and lower sides of the extrusion end. When the hook-shaped part is inserted, these sidewalls can guide the hook-shaped part, reducing interference and facilitating its insertion.

[0022] Furthermore, the installation of the cable ring 2 is achieved through a cover plate 6 at one end of the base 21. The cover plate 6 has multiple circumferentially distributed flexible sections 7, each with a thin wall structure. The center of the cover plate 6 has a through-hole 61. When the center hole 61, the through groove 211, and the connecting hole 222 are coaxially aligned, a cable hole is formed. During installation, the flexible section 7 is first passed through the connecting hole 101, and then bent by stamping to engage with the surface of the tarpaulin body 1, thus fixing the cable ring 2. The overall assembly process of the cable ring 2 is as follows: first, insert each compression block 3 into each opening 221; then, press the ring spring 4 into the slot 51; then, align each compression block 3 with the positioning slot 212; finally, fix the retainer in the through groove 211; and finally, fix the cover plate 6 to the retainer 22 to complete the overall assembly of the cable ring 2.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
