Description

Technical Field

[0001] This invention relates to the field of sports exercise equipment, and more particularly to a sports exercise device. Background Technology

[0002] Sports equipment is a general term for all kinds of equipment, gear, and supplies used in competitive sports and fitness exercises. Sports equipment and sports activities are interdependent and mutually reinforcing. Physical exercise can improve physical fitness, enhance health, and regulate mental well-being. With social development and improved living standards, people are increasingly aware of the importance of health and exercise.

[0003] However, traditional exercise equipment requires manual handling of the weights when adjusting them, which is inconvenient. Furthermore, because the weights are heavy, the weight changes significantly with each adjustment, making it difficult for exercisers to find the right balance. In addition, the impact of the weights when they fall generates considerable noise and can easily damage the equipment's parts. Summary of the Invention

[0004] In view of the shortcomings or deficiencies of the prior art, the present invention provides a sports exercise device that can adjust the weight of the water tank more conveniently and accurately, and can also cushion the sliding water tank when it falls, effectively reducing the noise generated when the sliding water tank falls, and better protecting the parts of the device.

[0005] The technical solution is as follows: A sports exercise device includes a base, a middle support, an upper support, a water tank, a counterweight movement component, a water pumping component, a water supply component, a water discharge component, and a rope length adjustment component.

A hollow piston rod is slidably connected inside the cylinder. The second check valve is fixedly connected inside the hollow piston rod. The lower magnet is fixedly connected to the top of the hollow piston rod and is in communication with the hollow piston rod.

[0008] Preferably, the water supply assembly includes a sliding bracket, a No. 3 one-way valve, an upper magnet, and a water injection hose. The sliding bracket is slidably connected to the sliding water tank, and the No. 3 one-way valve is fixedly connected to the sliding bracket. The upper magnet is fixedly connected to the bottom of the No. 3 one-way valve. The upper magnet and the lower magnet have opposite magnetic properties and attract each other. The No. 3 one-way valve is connected to the upper magnet. The top of the No. 3 one-way valve is fixedly connected to the water injection hose, and the end of the water injection hose away from the No. 3 one-way valve is fixedly connected to the sliding water tank. The water injection hose is connected to the sliding water tank.

[0009] Preferably, the water discharge assembly includes a faucet and a water discharge hose. The faucet is fixedly connected to the lower part of the sliding water tank, and the water discharge hose is fixedly connected to the upper part of the water storage tank. The end of the water discharge hose away from the water storage tank is fixedly connected to the faucet.

[0010] Preferably, the rope length adjustment assembly includes a rope length adjuster housing, a ratchet, a spool, a pawl, a spring plate, and a hand crank. The rope length adjuster housing is fixedly connected to the top of the sliding water tank. The pull rope passes through the rope length adjuster housing. A hand crank is rotatably connected to the rope length adjuster housing. A ratchet is fixedly connected to the hand crank. The ratchet is located inside the rope length adjuster housing. A spool is fixedly connected to the ratchet. The end of the pull rope away from the pull rod is fixedly connected to the spool. A pawl is rotatably connected to the upper part of the inner wall of the rope length adjuster housing. One end of the pawl is engaged between two teeth of the ratchet. A spring plate connects the pawl and the rope length adjuster housing.

[0011] Preferably, the system also includes a buffer assembly, which is disposed on an intermediate support. The buffer assembly includes a buffer spring and a buffer block. Each intermediate support is slidably connected to a buffer block. The tops of two buffer blocks respectively contact the bottoms of two guide blocks. Two buffer springs are connected between the buffer blocks and the intermediate support.

[0012] Preferably, a rubber pad is also included, with the top of the water tank fixedly connected to the rubber pad, which contacts the bottom of the sliding water tank.

[0013] Preferably, it also includes a tensioning wheel, with another tensioning wheel fixedly connected to the other roller, the pull rope contacting the tensioning wheel, and the pull rope located below the tensioning wheel.

[0014] Preferably, the rod also includes a sponge sleeve, with two sponge sleeves fixedly connected to the rod and arranged symmetrically.

[0015] This invention has the following advantages: First, the exerciser holds the lever and pulls it downwards, causing the hollow piston rod to move upwards and draw water from the storage tank into the cylinder. Then, the exerciser slowly releases the lever, causing the hollow piston rod to move downwards and push the water in the cylinder into the sliding water tank. When the sliding water tank is too heavy, the exerciser turns on the tap, and the water in the sliding water tank flows into the storage tank through the tap and drain hose, thus reducing the weight of the sliding water tank. When the weight of the sliding water tank is appropriate, the exerciser pushes the sliding bracket, preventing water from the storage tank from entering the sliding water tank. In this way, by increasing or decreasing the amount of water in the sliding water tank, the weight of the sliding water tank can be controlled more conveniently and accurately, making it suitable for more exercisers.

[0016] When the rope is too long, the user turns the hand crank, and the reel rotates to wind up the rope, making the unwinded portion the right length. When the rope is too short, the user presses the pawl and swings it upwards, causing the reel to unwind the rope, making the unwinded portion the right length. Then, the user releases the pawl, which engages between two teeth of the ratchet. This allows for better adjustment of the rope length, making the device suitable for users of different heights.

[0017] When the sliding water tank moves the four guide blocks downwards, the bottoms of two of the guide blocks will contact the tops of the two buffer blocks respectively, and the buffer springs will be compressed. When the sliding water tank moves the four guide blocks downwards, the bottoms of two of the guide blocks will disengage from the tops of the two buffer blocks respectively, and the buffer springs will return to their original position. In this way, the sliding water tank can be buffered when it falls, thereby effectively reducing the noise generated when the sliding water tank falls and better protecting the parts of this device.

[0030] The counterweight motion assembly includes guide blocks 51, sliding water tanks 52, rollers 53, rollers 54, pull ropes 55, and pull rods 56. Each intermediate support 2 has two guide blocks 51 slidably connected to it. The four guide blocks 51 are connected to the sliding water tanks 52 by bolts.

The cylinder 61 is bolted to the water storage tank 4. The first check valve 62 is bolted to the bottom of the cylinder 61, and the cylinder 61 is connected to the first check valve 62. The pumping pipe 63 is fixedly connected to the bottom of the first check valve 62, and the pumping pipe 63 is fixedly connected to the water storage tank 4. The pumping pipe 63 is connected to the water storage tank 4. The hollow piston rod 64 is slidably connected inside the cylinder 61. The second check valve 65 is bolted to the hollow piston rod 64, and the lower magnet 66 is bolted to the top of the hollow piston rod 64. The hollow piston rod 64 is connected to the lower magnet 66.

[0032] The water supply assembly includes a sliding bracket 71, a three-way valve 72, an upper magnet 73, and a water injection hose 74. The sliding bracket 71 is slidably connected to the sliding water tank 52. The three-way valve 72 is bolted to the sliding bracket 71. The upper magnet 73 is bolted to the bottom of the three-way valve 72. The upper magnet 73 and the lower magnet 66 have opposite magnetic properties and are attracted to each other. The three-way valve 72 is connected to the upper magnet 73. The water injection hose 74 is fixedly connected to the top of the three-way valve 72 and is connected to the water injection hose 74. The end of the water injection hose 74 away from the three-way valve 72 is fixedly connected to the sliding water tank 52 and is connected to the sliding water tank 52.

[0033] The water discharge assembly includes a faucet 81 and a water discharge hose 82. The faucet 81 is connected to the lower part of the sliding water tank 52 via a flange. The water discharge hose 82 is fixedly connected to the water storage tank 4. The end of the water discharge hose 82 away from the water storage tank 4 is fixedly connected to the faucet 81.

[0034] The rope length adjustment assembly includes a rope length adjuster housing 91, a ratchet 92, a winding spool 93, a pawl 94, a spring plate 95, and a hand crank 96. The top of the sliding water tank 52 is bolted to the rope length adjuster housing 91. The pull rope 55 passes through the rope length adjuster housing 91. The hand crank 96 is rotatably connected to the rope length adjuster housing 91. The ratchet 92 is connected to the hand crank 96 via a flat key. The ratchet 92 is located inside the rope length adjuster housing 91. The winding spool 93 is bolted to the ratchet 92. The end of the pull rope 55 away from the pull rod 56 is fixedly connected to the winding spool 93. The pawl 94 is rotatably connected to the upper part of the inner wall of the rope length adjuster housing 91. One end of the pawl 94 is engaged between two teeth of the ratchet 92. A spring plate 95 connects the pawl 94 and the rope length adjuster housing 91.

[0035] First, the exerciser grips the lever 56 and pulls it downwards. The downward movement of the lever 56 causes the rope 55 to move downwards, which in turn causes the two rollers 54 and two of the roller shafts 53 to rotate. The downward movement of the rope 55 also causes the sliding water tank 52 to move upwards. The upward movement of the sliding water tank 52 then drives the four guide blocks 51, the hollow piston rod 64, the second one-way valve 65, the lower magnet 66, the sliding bracket 71, the third one-way valve 72, the upper magnet 73, the water inlet hose 74, the faucet 81, and the water outlet hose... As pipe 82 moves upward, the hollow piston rod 64 moves upward, drawing water from the water tank 4 into the cylinder 61 via the water pipe 63 and the first one-way valve 62. Then, the exerciser slowly releases the pull rod 56. The sliding water tank 52, pull rope 55, four guide blocks 51, hollow piston rod 64, second one-way valve 65, lower magnet 66, sliding bracket 71, third one-way valve 72, upper magnet 73, water inlet hose 74, faucet 81, and water outlet hose 82 all move downward under gravity. The pull rope 55 then... The downward movement causes the two rollers 54 and two of the rollers 53 to rotate in opposite directions. The downward movement of the hollow piston rod 64 pushes the water in the cylinder 61 through the second one-way valve 65, the hollow piston rod 64, the lower magnet 66, the upper magnet 73, the third one-way valve 72, and the water injection hose 74 into the sliding water tank 52. This process repeats continuously, drawing water from the storage tank 4 into the sliding water tank 52, thus increasing the weight of the sliding water tank 52. When the sliding water tank 52 becomes too heavy, the exerciser will turn on the tap 81, causing the sliding water tank 52 to become too heavy. Water in tank 2 enters water storage tank 4 through faucet 81 and water hose 82, thereby reducing the weight of sliding water tank 52. When the weight of sliding water tank 52 is appropriate, the exerciser pushes sliding support 71, and upper magnet 73 and lower magnet 66 disengage, so that water in water storage tank 4 no longer enters sliding water tank 52. In this way, by increasing or decreasing the amount of water in sliding water tank 52, the weight of sliding water tank 52 can be controlled, making it more convenient and accurate to adjust the weight of sliding water tank 52, which is suitable for more exercisers.

[0036] When the pull rope 55 is too long, the exerciser turns the hand crank 96. Turning the hand crank 96 causes the ratchet 92 to rotate, which in turn causes the pawl 94 to swing upwards. The spring plate 95 is continuously compressed, and the ratchet 92 rotates the winding shaft 93. The winding shaft 93 then winds up the pull rope 55, causing the end of the pull rope 55 away from the sliding water tank 52 to move upwards. This upward movement of the pull rope 55 causes the lever 56 to move upwards, thus ensuring the unwinded length of the pull rope 55 is appropriate. When the pull rope 55 is too short, the exerciser presses the pawl 94 to swing upwards, causing the spring plate 95 to spring up. When the spring 95 is pressed down, the pawl 94 disengages from the ratchet 92, and the lever 56 moves downward under the influence of gravity. The downward movement of the lever 56 causes the rope 55 to move downward, which in turn causes the two winding spools 93 and the ratchet 92 to rotate in opposite directions. The two winding spools 93 unwind the rope 55, making the unwound portion of the rope 55 the appropriate length. Then, the exerciser releases the pawl 94, the spring 95 returns to its original position, and the pawl 94 engages between two of the ratchet teeth of the ratchet 92. This allows for better adjustment of the rope 55 length, making the device suitable for exercisers of different heights.

[0037] Example 2: Based on Example 1, such as Figures 2-9 As shown, it also includes a buffer assembly, which is set on the intermediate support 2. The buffer assembly includes a buffer spring 101 and a buffer block 102. Each intermediate support 2 is slidably connected to a buffer block 102. The tops of the two buffer blocks 102 respectively contact the bottoms of two guide blocks 51. The buffer blocks 102 and the intermediate support 2 are connected by two buffer springs 101 through hooks.

[0038] When the sliding water tank 52 moves the four guide blocks 51 downwards, the bottoms of two of the guide blocks 51 will contact the tops of the two buffer blocks 102 respectively, and the buffer springs 101 will be compressed. When the sliding water tank 52 moves the four guide blocks 51 downwards, the bottoms of two of the guide blocks 51 will disengage from the tops of the two buffer blocks 102 respectively, and the buffer springs 101 will return to their original position. In this way, the sliding water tank 52 can be buffered when it falls, thereby effectively reducing the noise generated when the sliding water tank 52 falls, and also better protecting the parts of this device.

[0039] Example 3: Based on Example 2, such as Figure 2 and Figure 3 As shown, it also includes a rubber pad 11. The top of the water storage tank 4 is fixedly connected to the rubber pad 11, which is made of rubber and contacts the bottom of the sliding water tank 52.

[0040] The rubber pad 11 can further cushion the sliding water tank 52 when it falls, thereby further reducing the noise generated when the sliding water tank 52 falls and better protecting the water storage tank 4.

[0041] Example 4: Based on Example 3, such as Figure 1 As shown, it also includes a tensioning wheel 12, and another roller 53 is bolted to the tensioning wheel 12. The pull rope 55 is in contact with the tensioning wheel 12 and is located below the tensioning wheel 12.

[0042] The tension wheel 12 makes the rope 55 more stable during up and down movement.

[0043] Example 5: Based on Example 4, such as Figure 1 As shown, it also includes a sponge sleeve 13. Two sponge sleeves 13 are sleeved on the pull rod 56, and the two sponge sleeves 13 are arranged symmetrically.

[0044] The sponge sleeve 13 increases the friction between the exerciser's palm and the lever 56, allowing the exerciser to grip the lever 56 more tightly.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
