DETAILED DESCRIPTION OF THE EMBODIMENTS

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those ordinarily skilled in the art without doing creative work shall fall within the protection scope of the present disclosure.

Refer toFIGS.1-6, a swimming pool cover includes a flexible cover layer1, wherein the flexible cover layer1is configured to completely cover a surface of a swimming pool; a flexible surrounding edge2, wherein the flexible surrounding edge2extends downwardly from an outer edge of the flexible cover layer1, so that the flexible surrounding edge2is suspended on an outer side wall of the swimming pool; a flexible wrapping edge3, wherein the flexible wrapping edge3is connected around a lower end of the flexible surrounding edge2, and the flexible wrapping edge3is provided with a plurality of fourth threading holes31; and a tightening wire4, wherein the tightening wire4passes through the plurality of the fourth threading holes31to attach the flexible wrapping edge3to the outer side wall of the swimming pool. Through the above structure, the flexible cover layer1is completely covered on the surface of the swimming pool, which can effectively block dust, fallen leaves, insects and other debris from entering the swimming pool, thereby keeping the pool water clean and reducing the frequency of cleaning and maintenance costs. The flexible surrounding edge2extending from the outer edge of the flexible cover layer1enables the swimming pool cover to be covered on the swimming pool in the form of a sleeve, increasing the stability of the swimming pool cover, and the lower end of the flexible surrounding edge2is also connected to the flexible wrapping edge3. By passing the tightening wire4through a plurality of threading holes provided on the flexible wrapping edge3, the tightening wire4tightens the flexible wrapping edge3while tightening the flexible surrounding edge2and the flexible cover layer to the outer side wall of the swimming pool, thereby further enhancing the wind resistance of the swimming pool cover, even in windy weather it is not easy to be blown up or blown away. The flexible wrapping edge3is designed to prevent the tightening wire4from damaging the flexible surrounding edge2, avoiding friction and pulling of the tightening wire4on the flexible surrounding edge2, thereby improving the overall durability and service life of the swimming pool cover.

In this embodiment, a tightening device5is also included. The tightening device5is arranged on the tightening wire4, and the tightening device5is configured to adjust a tightening length of the tightening wire4so that the flexible wrapping edge3is able to be attached on the outer side wall of the swimming pool of different sizes. Through the above structure, the tightening device5enhances the adaptability of the swimming pool cover. For swimming pools with a certain size variation, the user can adjust the tightening length of the tightening wire4by adjusting the tightening device5, which greatly improves the stability and convenience of using the swimming pool cover.

Specifically, the tightening device5is a wire twister, the tightening device5includes a wire twister shell51and a wire winding rod52, the wire twister shell51includes an upper shell511, a lower shell512arranged opposite to the upper shell511, a left shell513and a right shell514, the left shell513and the right shell514are connected to the upper shell511and the lower shell512and are arranged opposite to each other, two ends of the wire winding rod52are inserted between the upper shell511and the lower shell512, and the wire winding rod52is also connected to a rotating device6, and the wire winding rod52is configured to be rotated relative to the wire twister shell through the rotating device6. Through the above structure, the tightening wire4is brought into contact with the wire winding rod52, and then the wire winding rod52is rotated by twisting the rotating device6. When the wire winding rod52rotates, the tightening wire4is gradually wound around the wire winding rod52, and the length of the tightening wire4is shortened, so that the flexible wrapping edge3is gradually tightened and fits against the outer side wall of the swimming pool, so that the swimming pool cover is configured to be firmly installed on the outside of the swimming pool. Conversely, if the tightening wire4needs to be loosened, the rotating device6needs to be twisted in the opposite direction to gradually unwind the tightening wire4from the wire winding rod52, and then the swimming pool cover is configured to be taken off the swimming pool.

Furthermore, the rotating device6is a rotating arm61, one end of the wire winding rod52passes through the upper shell511and is connected to the rotating arm61, and the wire winding rod52is rotated relative to the wire twister shell by twisting the rotating arm61. The rotating arm61includes a first rotating arm611and a second rotating arm612, the first rotating arm611and the second rotating arm612are both in a “V” shape. Through the above structure, the user can place fingers respectively on the first rotating arm611and the second rotating arm612of the “V” shape and perform a relative twisting action to realize the rotation of the wire winding rod52, enabling the wire winding rod52to rotate more easily. Even when the tightening wire4requires a large tensile force, the adjustment can be easily completed. A “V” shape design provides a more comfortable grip, which makes the user more labor-saving when adjusting and improves the user experience.

In this embodiment, the wire twister further includes an one-way rotation mechanism7, the one-way rotation mechanism7is connected to the wire winding rod52so that the wire winding rod52is able to continuously rotate one-way relative to the wire twisting shell51. Through the above structure, the one-way rotation mechanism7can prevent the tightening wire4from loosening or slipping off after being adjusted. After the length of the tightening wire4has been adjusted, the tightening wire4will remain at a set length and tightness and will not change due to external forces.

Further, the one-way rotation mechanism7includes a ratchet71provided between the rotation device6and the upper shell511and a pawl72engaged with the ratchet71, the pawl72is fixed to the upper shell511by a pawl bolt73and is rotatable around the pawl bolt73, and the upper shell511is provided with an elastic device74, the elastic device74is pressed against one end of the pawl72away from the ratchet71so that the other end of the pawl72is engaged with the ratchet71. Specifically, the elastic device74is a spring741of “U” shape, the upper shell511is provided with a limiting hole5111, the spring741is located in the limiting hole5111, the spring741includes a first elastic column7411and a second elastic column7412, the first elastic column7411is pressed against the upper shell511, and the second elastic column7412is pressed against the pawl72. Through the above structure, the presence of the elastic device74ensures that the pawl72always remains engaged with the ratchet71during the rotation process, preventing the reverse rotation of the wire winding rod52during release, thereby maintaining a tensioning state of the tightening wire4, effectively ensuring that the tightening wire4can only be tensioned in one direction, avoiding loosening or slipping off due to external factors, and improving the stability of the tightening device5. This design is simple and reliable, ensuring the stability and reliability of the swimming pool cover.

In this embodiment, the left shell513is provided with a first threading hole5131, the right shell514is provided with a second threading hole5141, and the wire winding rod52is provided with a third threading hole521, one end of the tightening wire4is able to pass through the first threading hole5131and the third threading hole521in sequence and is wound around the wire winding rod52, and the other end of the tightening wire4is able to pass through the second threading hole5141and the third threading hole521in sequence and is wound around the wire winding rod52. Through the above structure, by passing two ends of the tensioning wire4through the first threading hole5131of the left shell513and the second threading hole5141of the right shell514respectively, while twisting the rotating arm61to move the wire winding rod52, two ends of the tensioning wire4are respectively wound around the wire winding rod52. With multiple rotations of the wire winding rod52, the intersection length of the tensioning wire4becomes smaller, thereby effectively achieving the result that the tensioning wire4tightens the swimming pool cover to the outer wall of the swimming pool.

In this embodiment, the first threading hole5131is provided with a first threading sleeve5132, and the second threading hole5141is provided with a second threading sleeve5142. Wherein the surface of the threading sleeve is made of smooth plastic material, and its surface smoothness can reduce the friction resistance of the tightening wire4during the threading process, making it easier for the tightening wire4to pass through the threading hole, and reducing the resistance and wear during operation.

In this embodiment, the flexible wrapping edge3includes a first layer of wrapping edge32and a second layer of wrapping edge33connected to the first layer of wrapping edge32, and the first layer of wrapping edge32and the second layer of wrapping edge33are clamped and fixed to front and back sides of the flexible surrounding edge2respectively. The first layer of wrapping edge32and the second layer of wrapping edge33are clamped to front and back sides of the flexible surrounding edge (2) by sewing. Wherein the material of the flexible wrapping edge3has better durability and structural strength than the flexible surrounding edge2and the flexible cover layer1, and it is configured to be made of cheesecloth, canvas, etc. Through the above structure, a two-layer structure of the flexible wrapping edge3is stronger and more durable than the flexible surrounding edge2, and improves the stability and durability of the swimming pool cover when the tightening wire4tightens it.

In this embodiment, at least one of the fourth threading holes31is provided with a threading ring311. In addition, the threading ring311is a steel threading ring311. Through the above structure, the steel threading ring311provides good durability and strength to ensure that the tightening wire4is not easily damaged during use and the flexible wrapping edge3is not easily torn.

In this embodiment, the flexible cover layer1and the flexible surrounding edge2are both made of oxford fabric. Through the above structure, the oxford cloth has a waterproof effect. With its good waterproof performance, the oxford cloth is configured to effectively prevent water from penetrating into the swimming pool. In addition, the oxford cloth is relatively lightweight, making it convenient for carrying and installing the swimming pool cover.

In this embodiment, the sides of the flexible cover layer1and the flexible surrounding edge2in contact with the swimming pool is covered with a silver heat-insulating coating. Through the above structure, a silver heat-insulating coating is configured to reduce the absorption and conduction of heat, helping to keep the/a water temperature of the swimming pool relatively stable.

In this embodiment, the outer edge of the tightening wire4is wrapped with a flexible protective layer41. The tightening wire4is a steel wire, and the flexible protective layer41is a transparent plastic sleeve. Through the above structure, the plastic sleeve is configured to reduce the potential risk of damage to the spool cover fabric or personnel by the sharp steel wire, improving the use safety, and the plastic sleeve is configured to reduce the friction between the steel tightening wire4and the fabric, thereby reducing wear and loss and maintaining the function and strength of the tightening wire4.

In this embodiment, a diameter of the flexible cover layer1ranges from 480 cm-1000 cm; a height of the swimming pool cover ranges from 15 cm-41 cm. Wherein, the height of the swimming pool cover refers to the height from the bottom surface of the flexible wrapping edge3to the top surface of the flexible cover layer1. In general swimming pool cover products, when the diameter of the flexible cover layer1is less than 550 cm, the height of the swimming pool cover is 20 cm; when the diameter of the flexible cover layer1is greater than 550 cm, the height of the swimming pool cover is 30 cm, so as to prevent the swimming pool cover from slipping off due to the excessive area of the flexible cover layer1and the excessively small height of the flexible surrounding edge2.
