[0040] Reference Figures 1 to 6 , a swimming pool cover, including a flexible covering layer 1, the flexible covering layer 1 is used to completely cover the surface of the swimming pool; a flexible edge 2, the flexible covering layer 1 extends downward along the outer periphery to form the flexible edge 2, so that the flexible edge 2 hangs on the outer side wall of the swimming pool; a flexible edging 3, the flexible edging 3 is connected around the lower end of the flexible edge 2, and a number of fourth threading holes 31 are provided on the flexible edging 3; a tightening wire 4, the tightening wire 4 passes through a number of fourth threading holes 31 to tighten the flexible edging 3 on the outer side wall of the swimming pool. Through the above structure, the flexible covering layer 1 completely covers the surface of the swimming pool, which can effectively prevent dust, fallen leaves, insects and other sundries from entering the swimming pool, thereby keeping the pool water clean and reducing the cleaning frequency and maintenance cost. And the flexible edge 2 extending from the outer periphery of the flexible covering layer 1 makes the swimming pool cover cover the swimming pool in a sleeved form, increasing the stability of the swimming pool cover. Moreover, the lower end of the flexible edge 2 is also connected with a flexible edging 3. By passing the tightening wire 4 through a number of threading holes provided on the flexible edging 3, when the tightening wire 4 tightens the flexible edging 3, it also tightens the flexible edge 2 and the flexible covering layer on the outer wall of the swimming pool, further enhancing the wind resistance of the swimming pool cover, and it is not easy to be blown up or displaced even in strong wind weather. The design of the flexible edging 3 is to prevent the damage of the tightening wire 4 to the flexible edge 2, avoiding the friction and pulling of the tightening wire 4 on the flexible edge 2, thereby improving the overall durability and service life of the swimming pool cover.

[0041] In this embodiment, a tightening device 5 is further included. The tightening device 5 is arranged on the tightening wire 4, and the tightening device 5 is used to adjust the tightening length of the tightening wire 4, so that the flexible edging 3 can be firmly tightened on the outer side walls of swimming pools with different sizes. Through the above structure, the tightening device 5 enhances the adaptability of the swimming pool cover. Under the condition of swimming pools with a certain size change, users can adjust the tightening length of the tightening wire 4 by adjusting the tightening device 5, greatly improving the stability and convenience of using the swimming pool cover.

[0042] Specifically, the tightening device 5 is a wire winder, which includes a wire winding housing 51 and a winding rod 52. The wire winding housing 51 includes an upper housing 511 and a lower housing 512 which are oppositely arranged, and a left housing 513 and a right housing 514 which are connected to the upper housing 511 and the lower housing 512 and are oppositely arranged. Both ends of the winding rod 52 penetrate between the upper housing 511 and the lower housing 512, and the winding rod 52 is also connected with a rotating device 6. The winding rod 52 can rotate relative to the wire winding housing 51 through the rotating device 6. With the above structure, the tightening wire 4 is touched with the winding rod 52, and then the rotating device 6 is twisted to realize the rotation of the winding rod 52. When the winding rod 52 rotates, the tightening wire 4 is gradually wound around the winding rod 52, and the length of the tightening wire 4 is shortened, so that the flexible edge 3 is gradually tightened and fitted on the outer side wall of the swimming pool, so as to realize that the swimming pool cover can be firmly sleeved on the outer side of the swimming pool. On the contrary, if it is necessary to loosen the tightening wire 4, the rotating device 6 needs to be twisted in the reverse direction to gradually untie the tightening wire 4 from the winding rod 52, and then the swimming pool cover can be taken off from the swimming pool.

[0043] Further, the rotating device 6 is a rotating arm 61. One end of the winding rod 52 passes through the upper housing 511 and is connected with the rotating arm 61. The winding rod 52 is rotated relative to the wire winding housing 51 by twisting the rotating arm 61. The rotating arm 61 includes a first rotating arm 611 and a second rotating arm 612 in a "V" shape. With the above structure, the user can respectively place the fingers on the "V"-shaped first rotating arm 611 and second rotating arm 612 and perform a relative twisting action to realize the rotation of the winding rod 52, so that the winding rod 52 can rotate more easily. Even when the tightening wire 4 requires a large pulling force, the adjustment can be easily completed. The "V" shape design provides a more comfortable grip, making the user more labor-saving during adjustment and improving the use experience.

[0044] In this embodiment, the wire winder further includes a one-way rotation mechanism 7, and the one-way rotation mechanism 7 is connected to the winding rod 52 so that the winding rod 52 can rotate continuously and unidirectionally relative to the wire winding housing 51. With the above structure, the one-way rotation mechanism 7 can prevent the tightening wire 4 from loosening or slipping off after being adjusted. After the length of the tightening wire 4 is adjusted, the tightening wire 4 will maintain the set length and tightness and will not change due to external forces.

[0045] Further, the one-way rotation mechanism 7 includes a ratchet wheel 71 disposed between the rotating device 6 and the upper housing 511, and a pawl 72 engaged with the ratchet wheel 71. The pawl 72 is fixed to the upper housing 511 by a pawl bolt 73. The pawl 72 can rotate around the pawl bolt 73. The upper housing 511 is provided with an elastic device 74. The elastic device 74 abuts against one end of the pawl 72 away from the ratchet wheel 71, so that the other end of the pawl 72 is engaged with the ratchet wheel 71. Specifically, the elastic device 74 is a spring 741 in an approximate "U" shape. The upper housing 511 is provided with a limiting hole 5111. The spring 741 is located in the limiting hole 5111. The spring 741 includes a first elastic column 7411 and a second elastic column 7412. The first elastic column 7411 abuts against the upper housing 511, and the second elastic column 7412 abuts against the pawl 72. With the above structure, the presence of the elastic device 74 ensures that the pawl 72 always remains engaged with the ratchet wheel 71 during rotation, prevents the reverse rotation of the winding rod 52 during release, thereby maintaining the tightened state of the tightening wire 4, effectively ensuring that the tightening wire 4 can only be tightened unidirectionally, avoiding loosening or slipping caused by external factors, improving the stability of the tightening device 5. This design is simple and reliable, ensuring the stability and reliability of the pool cover.

[0046] In this embodiment, the left housing 513 is provided with a first wire passing hole 5131, the right housing 514 is provided with a second wire passing hole 5141, and the winding rod 52 is provided with a third wire passing hole 521. One end of the tightening wire 4 can sequentially pass through the first wire passing hole 5131 and the third wire passing hole 521 and wind around the winding rod 52. The other end of the tightening wire 4 can sequentially pass through the second wire passing hole 5141 and the third wire passing hole 521 and wind around the winding rod 52. With the above structure, by passing the two ends of the tightening wire 4 through the first wire passing hole 5131 of the left housing 513 and the second wire passing hole 5141 of the right housing 514 respectively, when the rotating arm 61 is turned to move the winding rod 52, the two ends of the tightening wire 4 are respectively wound around the winding rod 52. After multiple rotations of the winding rod 52, the intersecting length of the tightening wire 4 becomes smaller, thereby effectively realizing that the tightening wire 4 tightens the pool cover on the outer wall of the pool.

[0047] In this embodiment, a first wire passing sleeve 5132 is sleeved on the first wire passing hole 5131, and a second wire passing sleeve 5142 is sleeved on the second wire passing hole 5141. Among them, the surface of the wire passing sleeve is made of a smooth plastic material, and its surface smoothness can reduce the frictional resistance of the tightening wire 4 during the wire passing process, making it easier for the tightening wire 4 to pass through the wire passing hole, and reducing the resistance and wear during operation.

[0048] In this embodiment, the flexible edge 3 includes a first layer of edge 32 and a second layer of edge 33 connected to the first layer of edge 32. The first layer of edge 32 and the second layer of edge 33 are respectively clamped and fixed to the front and back sides of the flexible perimeter 2. The first layer of edge 32 and the second layer of edge 33 are clamped to the front and back sides of the flexible perimeter 2 by stitching. Among them, the material of the flexible edge 3 is more durable and has greater structural strength than the flexible perimeter 2 and the flexible covering layer 1, and can be composed of coarse cotton cloth, canvas, etc. Through the above structure, the flexible edge 3 with a two-layer structure is more sturdy and durable than the flexible perimeter 2. When the tightening line 4 tightens it, the stability and durability of the pool cover can be improved.

[0049] In this embodiment, at least one fourth threading hole 31 is equipped with a threading ring 311. And the threading ring 311 is a steel threading ring 311. Through the above structure, the steel threading ring 311 provides good durability and strength to ensure that the tightening line 4 is not easily damaged during use and the flexible edge 3 is not easily torn.

[0050] In this embodiment, both the flexible covering layer 1 and the flexible perimeter 2 are made of Oxford cloth. Through the above structure, Oxford cloth has a waterproof effect, has good waterproof performance, and can effectively prevent moisture from penetrating into the pool. And Oxford cloth is relatively light, which is convenient for the carrying and installation of the pool cover.

[0051] In this embodiment, a silver thermal insulation coating is covered on the surface of the flexible covering layer 1 and the flexible perimeter 2 that contacts the pool. Through the above structure, the silver thermal insulation coating can reduce the absorption and conduction of heat, which helps to keep the water temperature in the pool relatively stable.

[0052] In this embodiment, the outer periphery of the tightening line 4 is wrapped with a flexible protective layer 41. The tightening line 4 is a steel wire, and the flexible protective layer 41 is a transparent plastic sleeve. Through the above structure, the plastic sleeve can reduce the potential damage risk of the sharp steel wire to the pool cover fabric or personnel, improve the use safety, and the plastic sleeve can reduce the friction between the steel wire tightening line 4 and the fabric, thereby reducing wear and loss and maintaining the function and strength of the tightening line 4.

[0053] In this embodiment, the diameter of the flexible covering layer 1 is 480 cm - 1000 cm; the height of the pool cover is 15 cm - 41 cm. Among them, the height of the pool cover refers to the height from the bottom surface of the flexible edge 3 to the top surface of the flexible covering layer 1. In general pool cover products, when the diameter of the flexible covering layer 1 is less than 550 cm, the height of the pool cover is 20 cm; when the diameter of the flexible covering layer 1 is greater than 550 cm, the height of the pool cover is 30 cm, so as to prevent the pool cover from slipping easily due to the too large area of the flexible covering layer 1 and the too small height of the flexible perimeter 2.

[0054] The above are one or more embodiments provided in combination with specific contents, and it is not considered that the specific implementation of the present utility model is limited only to these descriptions. All those that are similar or identical to the method, structure, etc. of the present utility model, or those that make several technical deductions or substitutions under the premise of the concept of the present utility model, should be regarded as the protection scope of the present utility model.
