Description

Technical Field

[0001] This application relates to the field of pool cover technology, and more specifically, to a tension pool cover. Background Technology

[0002] Existing outdoor swimming pools, exposed to the elements, easily accumulate dust, fallen leaves, insects, and other debris, causing water pollution. Therefore, pool covers, typically made of lightweight materials, are used to cover the pool when not in use. However, in actual use, because the fabric of these covers is so light, they are easily blown away or even swept away by strong winds.

[0003] Currently, pool covers are secured to pools using locking devices to prevent them from detaching. For example, Chinese utility model patent CN223151739U, entitled "A Pool Cover," discloses a locking mechanism using a rotating device and a ratchet. The rotating device employs a first and second rotating arm in a "V" shape. During rope tightening, the V-shaped rotating arm is twisted to rotate and rewind the cover. However, in the final tightening stage, the force applied by the fingers is significant, requiring considerable effort to tighten properly, making it laborious and inconvenient to use.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this application is to provide a tensioning pool cover that solves the problem in the prior art where tightening the pool cover requires twisting the V-shaped rotating arm with your fingers, which is inconvenient and requires considerable effort from your fingers.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides a tensioned pool cover, comprising: a flexible covering layer for surrounding and covering the pool; The tightening strap is fitted onto the flexible covering layer; Tensioner, tensioner includes: A stop seat and a tensioning seat are hinged together.

The winding shaft is located at the hinge of the stop seat and the tension seat; A one-way ratchet is provided on the winding shaft, and the tightening belt is wound on the winding shaft. By rotating the tensioning seat, the winding shaft is brought into a stopped state and a winding state. In the stopped state, the tensioning seat rotates toward the stop seat by being pulled, the second elastic limiting member disengages from the one-way ratchet, and the one-way ratchet, locked by the first elastic limiting member, prevents the winding shaft from rotating. In the winding state, the tensioning seat is pulled away from the stop seat and rotates. The first elastic limiter disengages from the one-way ratchet, and the one-way ratchet rotates with the tensioning seat under the locking of the second elastic limiter, causing the winding shaft to rotate. The tightening tape is wound up by rotating the winding shaft to tighten the covering layer to the outer wall of the pool.

[0007] Optionally, one end of the tightening band is fixed to the stop seat, and the other end of the tightening band is wound around the winding shaft. The tightening band is fitted onto the cover layer and surrounds the outer wall of the pool. The winding shaft rotates in a directional manner as the tensioner swings back and forth to wind up the tensioning tape.

[0008] Optionally, the winding shaft includes: a first bow-shaped shaft and a second bow-shaped shaft, both of which are mounted on a one-way ratchet, and both the stop seat and the tensioning seat are rotatably mounted on the first bow-shaped shaft and the second bow-shaped shaft; A threading cavity is formed by the gap between the first and second bow-shaped shafts.

[0009] Optionally, the tensioning seat includes: a tensioning bracket, which is rotatably mounted on the winding shaft portion; The rubber sleeve handle is fixedly mounted on the end of the tension bracket away from the winding shaft.

[0010] Optionally, the rubber sleeve handle includes: a sleeve layer that covers the top of the tensioning bracket; A cylindrical top is set on top of the sleeve layer, and the outer diameter of the cylindrical top is larger than the thickness of the sleeve layer; Among them, obtuse-angle openings are formed on both sides of the width direction of the sleeve layer, and reinforcing ribs are fixedly installed inside the obtuse-angle openings; The outer surface of the top of the column is provided with a second anti-slip texture.

[0011] Optionally, the second elastic limiting member includes: a second locking block, which is slidably disposed in the second guide groove of the tensioning bracket; The second spring connects the second locking block and the tensioning bracket. The second spring applies a spring force to the second locking block so that the second locking block abuts against the locking teeth of the one-way ratchet. A rubber sleeve handle is provided on the second locking block. The handle has a handle position facing outwards from the tensioning bracket.

[0012] Optionally, the rubber sleeve handle includes: a rubber coating layer that wraps around the second locking block; The protruding rubber block is connected to the top of the coated rubber layer and forms a stepped handle position between the protruding rubber block and the coated rubber layer; A thick padding layer is provided on the surface of the handle area; The surface of the handle or the surface of the padding layer is provided with a first uneven anti-slip part.

[0013] Optionally, the tensioning seat includes: tensioning side plates located on both sides of the width, and a second support plate connecting the tensioning side plates on both sides; The second support plate is located near the top of the tensioning side plate so that a cavity is formed on the side of the second support plate facing the winding shaft, and the rubber sleeve handle is located in the cavity.

[0014] Optionally, the stop seat includes: stop side plates located on both sides of the width, and a first support plate connecting the stop side plates on both sides, the two stop side plates and the first support plate forming a first inner cavity, and a first elastic limiting member disposed in the first inner cavity; A shaft is fixedly installed at one end of the stop plates on both sides, and one end of the tightening belt is connected to the shaft.

[0015] Optionally, the flexible covering layer includes a middle portion and an outer portion, with the outer portion connected to the middle portion. The middle portion is used to cover the pool opening of the pool, and the outer portion is used to surround the outer wall of the pool. The outer part is provided with a hanging ear, which has a rope opening, and the tightening strap is inserted into the rope opening; The hanging lug is also equipped with a mounting port, which is located below the rope threading port. The mounting port is used to connect to counterweights or ground stakes. The outer part is also equipped with a cover, which can be attached to the outer part by Velcro and is used to cover the tensioner.

[0016] The beneficial effects of the tension pool cover provided in this application are at least as follows: After the flexible cover layer is fitted onto the outer wall of the pool, a loop structure is formed by connecting the tension band to the stop seat and the winding shaft, which can fit around the circumference of the flexible cover layer. The first and second elastic limiting members engage with the teeth on the one-way ratchet to achieve the one-way rotation positioning function of the one-way ratchet. The entire palm can hold the end of the tension seat and pull and push back, thereby achieving the rotation of the tension seat. When the tension seat rotates away from the stop seat, the winding shaft is in a winding state. In this state, the first elastic limiting member moves along the arc-shaped guide surface of the teeth and disengages from the one-way ratchet. The stop surface of the teeth of the one-way ratchet is locked by the second elastic limiting member, so that the one-way ratchet rotates with the tension seat, causing the winding shaft to rotate, thereby driving one end of the tension band to be wound on the winding shaft, tightening the entire tension band. When the tensioner rotates towards the stop (during return), the winding shaft is stopped. In this state, the second elastic limiter moves along the arc-shaped guide surface of the locking teeth and disengages from the one-way ratchet. The stop surface of the one-way ratchet's locking teeth, locked by the first elastic limiter, keeps the one-way ratchet and the stop station stationary, preventing the winding shaft from rotating. Therefore, by repeatedly pushing the tensioner, the winding shaft can be intermittently rotated to continuously wind up the tensioning tape, thus securing the cover layer to the outer wall of the pool. During use, force is applied by holding the end of the tensioner; the tensioner achieves one-way tightening through the mechanical ratchet structure, reducing the risk of loosening due to swaying in strong winds. Compared to traditional rope-tying methods, it offers greater ease of operation, allowing for quick and easy fixing with over ten times the efficiency. Furthermore, pushing and pulling with the palm of the hand makes it easier to apply force, reducing manual effort by approximately 50%, making it more convenient to use. Attached Figure Description

[0023] like Figure 1 , Figure 2 As shown, this embodiment proposes a tension-type pool cover for covering a pool when it is not in use. This tension-type pool cover mainly includes: a flexible covering layer 100, a tightening strap 200, and a tensioner 300. The flexible covering layer 100 is used to surround and cover the pool. The flexible covering layer 100 includes a middle portion 110 and an outer portion 120, the outer portion 120 being connected to the middle portion 110. The middle portion 110 covers the pool opening, and the outer portion 120 surrounds the outer wall of the pool. The tightening strap 200 is fitted onto the outer portion 120 of the flexible covering layer 100 to secure the outer portion 120 to the outer wall of the pool. Specifically, a loop 130 is provided on the outer portion 120. Multiple loops 130 can be provided, spaced apart circumferentially along the outer portion 120. Each loop 130 has a loop opening 131 through which a tightening strap 200 is threaded, allowing it to wrap around the outer portion 120. The tightening strap 200 is then wound up and locked by a tensioner 300. Alternatively, a single loop 130 can wrap around the outer portion 120, also enabling connection to the tightening strap 200.

[0024] like Figure 1 , Figure 2As shown, the tensioner 300 of this embodiment mainly includes: a stop seat 310 and a tensioning seat 350 hinged together, a winding shaft portion 330, and a one-way ratchet 340. A first elastic limiting member 320 is provided on the stop seat 310, and a second elastic limiting member 380 is provided on the tensioning seat 350. The winding shaft portion 330 passes through the hinge of the stop seat 310 and the tensioning seat 350. In use, the end of the stop seat 310 connected to the tensioning band 200 is fixed to the outer portion 120, and the tensioning seat 350 rotates back and forth about the central axis of the winding shaft portion 330. The one-way ratchet 340 is fixed to the winding shaft portion 330, and the other end of the tensioning band 200 is wound around the winding shaft portion 330 so that the tensioning band 200 is fitted onto the cover layer and surrounds the outer wall of the pool. By rotating the tensioning seat 350, the winding shaft 330 is in a stopped state and a winding state. The back-and-forth swinging of the tensioning seat 350 causes the winding shaft 330 to cycle through these states, resulting in directional, intermittent rotation of the winding shaft 330 and gradually winding up the other end of the tensioning tape 200. In the stopped state, the tensioning seat 350 rotates towards the stop seat 310 by pulling, and the second elastic limiting member 380 disengages from the one-way ratchet 340. The one-way ratchet 340, locked by the first elastic limiting member 320, prevents the winding shaft 330 from rotating. In the winding state, the tensioning seat 350 rotates away from the stop seat 310 by pulling, and the first elastic limiting member 320 disengages from the one-way ratchet 340. The one-way ratchet 340, locked by the second elastic limiting member 380, rotates with the tensioning seat 350, causing the winding shaft 330 to rotate. The tightening strap 200 is wound up by rotating the winding shaft 330 to tighten the cover layer to the outer wall of the pool. After the flexible cover layer 100 is fitted onto the outer wall of the pool, the tightening strap 200 is connected to the stop seat 310 and the winding shaft 330 to form a loop structure that can fit around the circumference of the flexible cover layer 100. The first elastic limiting member 320 and the second elastic limiting member 380 make active contact with the teeth on the one-way ratchet 340 to realize the one-way rotation positioning function of the one-way ratchet 340. The entire palm can grasp the end of the tensioning seat 350 to pull and push back, thereby realizing the rotation of the tensioning seat 350. When tightened... When seat 350 rotates away from stop seat 310, the winding shaft portion 330 is in a winding state. In this state, the first elastic limiting member 320 moves along the arc-shaped guide surface 342 of the locking teeth and disengages from the one-way ratchet 340. The stop surface 341 of the locking teeth of the one-way ratchet 340 is locked by the second elastic limiting member 380, so that the one-way ratchet 340 rotates with the tensioning seat 350, causing the winding shaft portion 330 to rotate, thereby driving one end of the tensioning tape 200 to be wound on the winding shaft portion 330, so that the entire tensioning tape 200 is tightened.When the tensioner 350 rotates toward the stop 310 (during return), the winding shaft 330 is stopped. In this state, the second elastic limiter 380 moves along the arc-shaped guide surface 342 of the locking teeth and disengages from the one-way ratchet 340. Under the locking of the first elastic limiter 320, the stop surface 341 of the locking teeth of the one-way ratchet 340 locks the one-way ratchet 340 and the stop 310 together, thus preventing the winding shaft 330 from rotating. Therefore, by repeatedly pushing the tensioner 350, the tensioner 300 can make the winding shaft 330 rotate intermittently and continuously wind, thereby locking the tensioning tape 200 and securing the cover layer to the outer wall of the pool. During use, force is applied by holding the end of the tensioner 350. The tensioner 300 achieves one-way tightening through the mechanical ratchet structure, reducing the risk of loosening due to swaying during strong winds. Compared to traditional rope-tying methods, this method offers greater ease of use, allowing for quick and easy securing, increasing efficiency by over ten times. Furthermore, the palm of the hand facilitates pushing and pulling, making it easier to apply force and reducing manual effort by approximately 50%, resulting in greater convenience.

[0025] For ease of structural description, the axial direction of the winding shaft 330 in the tensioner 300 is the width direction. The width direction will be used as the left-right direction for structural explanation. When the tensioner 300 is in use, the side of the tensioning seat 350 that rotates towards the stop seat 310 is the inner side, and the side away from the stop seat 310 is the outer side.

[0026] like Figure 2 , Figure 3 As shown, the stop seat 310 of this embodiment specifically includes: stop side plates 311 located on the left and right sides spaced apart, and a first support plate 312 connecting the stop side plates 311 on the left and right sides. The first support plate 312 is located on the outer edge of the stop side plates 311, so that the left and right stop side plates 311 and the first support plate 312 form a first inner cavity 313. A first elastic limiting member 320 is disposed in the first inner cavity 313. The first elastic limiting member 320 specifically includes: a first locking block 321 and a first spring 322. The first locking block 321 is slidably disposed within the first guide groove 314 of the stop plates 311 on both sides. A first spring 322 connects the first locking block 321 and the first support plate 312. The first spring 322 applies a spring force to the first locking block 321, causing it to abut against the teeth of the one-way ratchet 340. Thus, in the stopped state, the first locking block 321 abuts against the stop surface 341, preventing the one-way ratchet 340 from rotating. In the reeling-in state, the first locking block 321 can be pushed along the arc-shaped guide surface 342, causing the one-way ratchet 340 to rotate. A shaft 315 is fixedly disposed at one end of each of the stop plates 311 on both sides. Figure 1 As shown, one end of the tightening strap 200 is sleeved and fixed on the shaft 315.

[0027] like Figure 2 , Figure 3 , Figure 4 As shown, the winding shaft portion 330 of this embodiment specifically includes: a first bow-shaped shaft 331 and a second bow-shaped shaft 332. Both the first bow-shaped shaft 331 and the second bow-shaped shaft 332 are disposed on a one-way ratchet 340. Specifically, the one-way ratchet 340 has two bow-shaped holes, one above the other. The first bow-shaped shaft 331 and the second bow-shaped shaft 332 are respectively inserted into the two bow-shaped holes, so that the first bow-shaped shaft 331, the second bow-shaped shaft 332 and the one-way ratchet 340 can rotate together. The first bow-shaped shaft 331 and the second bow-shaped shaft 332 are symmetrically arranged around the rotation center (the central axis of the winding shaft portion 330). Both the stop seat 310 and the tension seat 350 are rotatably mounted on the first bow-shaped shaft 331 and the second bow-shaped shaft 332. Two one-way ratchet wheels 340 are respectively located on the left and right sides of the stop plate 311. The first bow-shaped shaft 331 and the second bow-shaped shaft 332 both pass through the stop plates 311 on both sides. Locking parts 333, such as pins or cotter pins, are provided at both ends of the first bow-shaped shaft 331 and the second bow-shaped shaft 332, limiting the one-way ratchet wheels 340, the stop seat 310, and the tension seat 350 in the left-right direction to achieve a stable connection. A threading cavity 334 is formed between the left and right stop plates 311 and between the first bow-shaped shaft 331 and the second bow-shaped shaft 332. This threading cavity 334 is used to thread the other end of the fixing strap 200, facilitating the fixing of the other end of the fixing strap 200 to the winding shaft 330.

[0028] like Figure 2 , Figure 3 , Figure 4 As shown, the tensioning seat 350 in this embodiment specifically includes a tensioning bracket 360 and a rubber sleeve handle 370. The tensioning bracket 360 is rotatably mounted on the winding shaft portion 330. In its specific structure, the tensioning bracket 360 includes tensioning side plates 361 located on the left and right sides, and a second support plate 362 connecting the tensioning side plates 361 on both sides and located on the outer edge of the tensioning side plates 361. The rubber sleeve handle 370 is fixedly mounted on one end of the tensioning bracket 360 away from the winding shaft portion 330. The rubber sleeve handle 370 provides a gripping position for the palm during the back-and-forth pulling of the tensioning seat 350, making it convenient to apply force to the tensioning bracket 360. The distance from the end of the rubber sleeve handle 370 to the central axis of the winding shaft portion 330 is a first distance, and the distance from the center of the shaft to the central axis of the winding shaft portion 330 is a second distance. The length of the first distance is greater than the second distance, which makes it easier to push the tensioning seat 350.

[0029] like Figure 2 , Figure 3 , Figure 4As shown, the rubber sleeve handle 370 of this embodiment specifically includes: a sleeve layer 371 and a cylindrical top 372. The sleeve layer 371 covers the top of the tensioning bracket 360. For example, the sleeve layer 371 can wrap and fix the end of the tensioning side plate 361 and the end of the second support plate 362, thereby making the rubber sleeve handle 370 more stably fixed on the tensioning seat 350. The cylindrical top 372 is disposed on the top of the sleeve layer 371. The outer diameter of the cylindrical top 372 is larger than the thickness of the sleeve layer 371. When in use, the hand grasps the cylindrical top 372, and the arc shape matches the grip shape of the palm, making it more convenient to apply pushing and pulling force.

[0030] like Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, obtuse-angled openings 373 are formed on the left and right sides of the sleeve layer 371, and reinforcing ribs 375 are fixedly provided inside the obtuse-angled openings 373. By providing reinforcing ribs 375 on the left and right sides, the structure of the entire sleeve layer 371 is increased, the load-bearing capacity is increased, and the connection with the tensioning bracket 360 is more stable. A second concave-convex anti-slip part 374 is provided on the outer surface of the cylindrical top 372. The second concave-convex anti-slip part 374 can increase the friction of the cylindrical top 372, making it less slippery when gripped and pushed, and more convenient to use.

[0031] like Figure 2 , Figure 3 , Figure 4 As shown, the second elastic limiting member 380 in this embodiment specifically includes: a second locking block 381, a second spring 382, ​​and a rubber-sleeved handle 383. The second locking block 381 is slidably disposed in the second guide groove 351 of the tensioning bracket 360. The second spring 382 connects the second locking block 381 and the tensioning bracket 360, and applies elastic force to the second locking block 381 so that the second locking block 381 abuts against the teeth of the one-way ratchet 340, thereby realizing the function of cooperating with the teeth of the one-way ratchet 340. The rubber-sleeved handle 383 is disposed on the second locking block 381, and the rubber-sleeved handle 383 has a handle position 386 facing the outside of the tensioning bracket 360. When it is necessary to loosen the winding spool 330 to unwind the tensioning strap 200, the rubber sleeve handle 370 is lifted away from the winding spool 330, thereby disengaging the second locking block 381 from the teeth of the one-way ratchet 340, thus loosening the winding spool 330. The handle 386 provides a point of leverage for the lifting fingers, making it easy for the fingers to hook onto the rubber sleeve handle 383.

[0032] like Figure 2 , Figure 3 , Figure 4As shown, the second support plate 362 is close to the top of the tensioning side plate 361, so that the second support plate 362 forms a cavity 363 on the side facing the winding shaft portion 330, and the rubber sleeve handle 383 is located in the cavity 363. Specifically, the rubber sleeve handle 383 in this embodiment includes: a covering rubber layer 384 and an outwardly protruding rubber block 385. The covering rubber layer 384 wraps around the second locking block 381, thereby stably fixing the rubber sleeve handle 383 to the second elastic limiting member 380. The outwardly protruding rubber block 385 is connected to the top of the covering rubber layer 384, forming a stepped handle position 386 between them. A padding layer 387 is provided on the surface of the handle position 386. The padding layer 387 thickens the outwardly protruding rubber block 385, strengthening the structure and making the entire rubber sleeve handle 383 less prone to breakage. It also facilitates hooking fingers onto the outwardly protruding rubber block 385. A first concave-convex anti-slip part 388 is provided on the surface of the handle position 386 or the surface of the padding layer 387. This can increase the friction between the finger and the surface of the outward convex rubber block 385. When the finger applies upward force, it is not easy to fall off the rubber handle 383, making it more convenient to use.

[0033] like Figure 1 , Figure 5 As shown, the hanging ear 130 in this embodiment is also provided with a hanging opening 132. The hanging opening 132 can be connected to a counterweight or a ground stake to further tighten the outer part 120 of the pool cover to prevent the pool cover from being blown up or shifted. In the specific structure, both the hanging opening 132 and the rope threading opening 131 are provided on the hanging ear 130, with the hanging opening 132 located below the rope threading opening 131. For example, the hanging ear 130 includes a bottom strap 133 and an outer strap 134 sewn onto the bottom strap 133. The upper end of the outer strap 134 is sewn onto the bottom strap, and the middle of the outer strap 134 is sewn onto the bottom strap 133, thus forming the rope threading opening 131 at the top. The lower end of the outer strap 134 is bent and sewn together with the middle of the outer strap to form the hanging opening 132 at the bottom. The bottom strap is sewn onto the outer part 120 to form the hanging ear 130.

[0034] like Figure 1 , Figure 5 As shown, a cover 140 is also provided on the outer portion 120. The cover 140 can be attached to the outer portion 120 by Velcro 143 and is used to cover the tensioner 300. In the specific structure, the bottom layer 141 of the cover 140 is sewn to the outer portion 120 and is located at the position of the tensioner 300. The top layer 142 of the cover 140 can be folded and connected to the bottom layer 141 by Velcro 143. Velcro 143 is provided on the upper end or multiple sides (upper end, left end and right end) of the top layer 142. By flipping the top layer 142 of the cover 140, the top layer 142 of the cover 140 can be attached to the outer portion 120 to achieve connection and cover the tensioner 300 to conceal the tensioner 300.

[0035] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
