DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

To make the object, the technical solution, and the advantage of the present disclosure more clearly, the present disclosure is further described in detail below with reference to the accompanying embodiments. It should be understood that the specific embodiments described herein are just a part of rather than all the embodiments of the present disclosure. All other embodiments obtained by one skilled in the art without inventive works based on the embodiment of the present disclosure, fall into the protection scope of the present disclosure.



FIGS. 1 to 3 show the structure of the waterproof cover for outdoor products according to an embodiment of the present disclosure. The waterproof cover for outdoor products as shown in FIGS. 1-3 can be placed on an outdoor product to prevent the outdoor product from being affected by rain and affecting its lifespan. The outdoor waterproof cover for outdoor products according to the present embodiment includes a tarpaulin 10, a tensioning assembly 30, a support column assembly 40, and four binding straps 20. The four binding straps 20 are divided into two pairs that are diagonally distributed. The support column assembly 40 and four binding straps 20 are respectively fastened to the tarpaulin 10. The tarpaulin 10 is fastened to outdoor products by four binding straps 20. In other embodiments, the number of binding straps 20 can be different, for example, the number of binding straps 20 can be three, five, six, etc.


The tarpaulin 10 is made of materials with good waterproof performance and good flexibility. For example, the tarpaulin 10 can be composite fabrics which composed of polymer waterproof, breathable materials and fabrics. The tarpaulin 10 includes a ceiling part 11. The ceiling part 11 is not planar, and the center 113 of the ceiling part 11 is convex. Of course, in other embodiments, a sun protection layer can also be made on the surface of the tarpaulin 10 to improve its sun protection performance.


Each binding strap 20 is made of flexible materials and is used to fasten to outdoor products. For example, the binding strap 20 can be made of fiber fabric, and one end of each binding strap 20 is fastened to the edge of the ceiling part 11. Specifically, the fixing points of multiple binding straps 20 and the ceiling part 11 can be located at the multiple vertices of the same rectangle or polygon to improve the stability of the fixation of the ceiling part 11. The tensioning assembly 30 is made of flexible materials. The edge of the tensioning assembly 30 is fastened to the edge of the inner surface of the ceiling part 11. The tensioning assembly 30 is tensioned when the binding straps 20 are respectively tied to the outdoor product. The length of each binding strap 20 is enough to be fastened to the outdoor product. In addition, the free end of each binding strap 30 can also be provided with a Velcro, an elastic rope, a hook, etc., so as to facilitate fasten to the outdoor product.


The support column assembly 40 is roughly columnar in shape and is rigidity in axial. The top end of the support column assembly 40 is fastened to the inner surface of the center of the ceiling part 11 of the tarpaulin 10, and the bottom end of the support column assembly 40 is fastened to the center of the tensioning assembly 30. When the support column assembly 40 is in a tensioned state, the center of the ceiling part 11 is jacked up and the ceiling part 11 forms a tensioned slope 111 above the outdoor product by the support force provided by the tensioning assembly 40.


The waterproof cover described above is fastened to the outdoor product by fastening the binding straps 20 to the outdoor product. When the tensioning assembly 30 is tensioned, the center of the ceiling part 11 of the tarpaulin 10 is jacked up by the tensioning assembly 30 and the support column assembly 40, and the ceiling part 11 forms one or more slopes 111. Therefore, raindrops that fall on the ceiling part 11 can flow downward along the slope 111 under the action of gravity, avoiding water accumulation in the ceiling part 11 of the tarpaulin 10. Due to the lack of a rigid support rod at the edge of the ceiling part 11 and the fact that there is only one support column assembly 40 with a smaller size in axial, the waterproof cover can be conveniently folded and stored when not in use. People just bind the binding straps 20 to the outdoor product when using the waterproof cover, and need not to build a support frame.
