DETAILED DESCRIPTION

[0038] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] See also Figure 1-10 The present embodiment provides a weight loss and stretching exercise equipment and a method of use, including a main body 1 of the exercise equipment, the main body 1 is a water resistance rowing machine with a reference model of HS-4000, and the main body 1 includes a track, a sliding seat, a pull rope, a handle, a pedal, a plurality of pulleys and a unidirectional rotating shaft. One end of the slide rail of the main body 1 is set as a frame, and a water tank 2 is fixedly installed in the frame. The upper and lower ends of the water tank 2 are respectively provided with a liquid injection port and a liquid discharge port, and the liquid injection port and the liquid discharge port are both closed by a cover. A rotating wheel 21 is rotatably installed in the water tank 2, and five paddles 3 are connected to the outer wall of the rotating wheel 21. The five paddles 3 are connected to the outer wall of the rotating wheel 21 in a circular array with the rotating wheel 21 as the center of the circle, and are evenly rotated and connected to the outer wall of the rotating wheel 21. A rotating shaft 22 is rotatably plugged into the upper end of the water tank 2, and the rotating shaft 22 is fixedly connected to the upper end of the rotating wheel 21.

[0041] The overall sports equipment uses a water-resistance rowing machine with the same reference model HS-4000. Before use, remove the cover of the liquid filling port and inject liquid into the water tank 2. The liquid is usually water. After the liquid level is higher than the paddle 3, use the cover to close the liquid filling port. Then, the user sits on the sliding seat, bends his legs, steps his feet on the pedals, and holds the handles with both hands. When in use, the user straightens the legs and pulls the handle simultaneously. The force generated when the legs are straightened will push the sliding seat to slide on the track. The movement of the handle drives the pull rope to be pulled. The movement of the pull rope drives the rotating shaft 22 to rotate through multiple pulleys and a one-way rotating shaft. The rotating shaft 22 drives the rotating wheel 21 to rotate, that is, drives the blade 3 to rotate in the water tank 2. The driving force of the blade 3 contacting the liquid is then generated through the resistance of the pull rope to the user. A coil spring is also installed in the main body 1. The coil spring drives the pull rope to generate recovery power. After the user completes a set of rowing movements, the user unloads the force with his hands and bends his legs and feet. The elastic force of the coil spring drives the pull rope to shrink and reset. Since the one-way rotating shaft can only drive the rotating shaft 22 to rotate in one direction, after the pull rope shrinks and resets, it will not drive the rotating wheel 21 and the blade 3 to reverse in the water tank 2. The user uses the sports equipment by imitating the rowing movement, thereby driving about 80% of the muscles in the body to exercise, thereby achieving the effect of weight loss and stretching.

[0042] Since users of different physical abilities have different strengths, for example, beginners and children have low strength and poor proficiency in use, while advanced users and young people have strong strength and are easier to use, therefore, in order to adapt to users of different physical abilities, the blade 3 is rotatably connected to the rotating wheel 21, and the rotating wheel 21 is equipped with an adjustment mechanism for controlling the rotation of the blade 3. The adjustment mechanism includes a driving gear 41, a driven gear 42 and a dial wheel 43, such as Figure 7As shown, the driving gear 41 is configured as a bevel gear disk, the driven gear 42 is configured as a bevel gear, the driving gear 41 and the driven gear 42 are both rotatably mounted inside the rotating wheel 21, the driven gear 42 is configured as five, and the driven gear 42 is fixedly connected to one end of the blade 3, the driving gear 41 is meshed with the upper ends of the five driven gears 42, the paddle wheel 43 is rotatably mounted on the upper end of the water tank 2, and the paddle wheel 43 is rotatably sleeved on the outer side wall of the rotating shaft 22. A connecting rod is fixedly connected between the paddle wheel 43 and the driving gear 41, wherein two connecting rods are configured, and the two connecting rods are symmetrically arranged, and two arc grooves are provided at the upper end of the rotating wheel 21, and the connecting rods are slidably mounted in the arc grooves.

[0043] When in use, the driving gear 41 can be driven to rotate by rotating the dial wheel 43 through the connecting rod. The driving gear 41 can drive the five driven gears 42 to rotate synchronously. The driven gear 42 can adjust the angle of the blade 3 by rotating. The contact surface between the blade 3 and the liquid can be changed by rotating and adjusting the angle of the blade 3. When the blade 3 is perpendicular to the ground, the contact surface between the blade 3 and the liquid is the largest, and the resistance generated by the liquid to the blade 3 is the largest. At this time, the force required to pull the pull rope through the handle is the largest. After the blade 3 is rotated through the adjustment mechanism so that the blade 3 is parallel to the ground, the thinner blade 3 has the smallest contact surface with the liquid, and the cutting angle of the water flow is the smallest, thereby reducing the direct contact area of ​​the water on the blade, resulting in a reduction in resistance.

[0044] However, in actual operation, it is found that when the blade 3 rotates, the resistance of the liquid will drive the blade 3 to rotate, and then the driving gear 41, the driven gear 42 and the connecting rod will drive the dial wheel 43 to rotate on the water tank 2. At this time, the resistance between the rotation of the blade 3 and the liquid cannot be fixed, and the resistance applied to the user is also unstable. In order to fix the blade 3, a ring 5 is installed on the outer wall of the rotating shaft 22 to slide up and down. The outer wall of the rotating shaft 22 is provided with a plurality of slide bars. The inner wall of the ring 5 is provided with a strip groove matching the slide bar. When the ring 5 slides up and down, the slide bar slides in the strip groove, and then the slide bar prevents the ring 5 from rotating horizontally on the outer wall of the rotating shaft 22. Figure 6 and Figure 8 As shown, the lower end of the collar 5 is fixedly connected to a plurality of clamping rods 51, and the plurality of clamping rods 51 are evenly arranged in a circular array with the rotating shaft 22 as the center. Figure 7 and Fig. 9As shown, the upper end of the dial wheel 43 is provided with a plurality of locking holes, which are also evenly arranged in a circular array with the rotating shaft 22 as the center. After rotating the dial wheel 43 to determine the rotation angle of the blade 3, the collar 5 is slid downward to insert the locking rod 51 into the locking hole on the dial wheel 43. At this time, the dial wheel 43 can be fixed to prevent the dial wheel 43 from rotating. The fixing of the dial wheel 43 can lock the driving gear 41 and the driven gear 42, thereby fixing the angle of the blade 3 to prevent the blade 3 from rotating due to the resistance of the liquid. In theory, the more the locking rods 51 and the locking holes, the more angles the blade 3 can be fixed.

[0045] During the user's exercise, the operation of the internal structure of the device and the user's movement will drive the entire device to vibrate. This vibration may cause the ring 5 to move, causing the locking rod 51 to disengage from the locking hole of the dial wheel 43. Therefore, in order to prevent the locking rod 51 from disengaging from the locking hole when the exercise device is in operation, a spring 52 is sleeved on the outer wall of the rotating shaft 22. Figure 7 and Figure 8 As shown, the spring 52 is located inside the collar 5. The spring 52 applies a downward elastic force to the collar 5. The elastic force of the spring 52 and the weight of the collar 5 and the spring 52 can prevent the vibration of the sports equipment from causing the clamping rod 51 to disengage from the clamping hole.

[0046] When the dial wheel 43 needs to be rotated to adjust the angle of the blade 3, the ring 5 needs to be moved upward on the outer wall of the shaft 22 by hand. At this time, the spring 52 is compressed, and the lever 51 is disengaged from the hole, so that the dial wheel 43 can be rotated with the other hand.

[0047] The characteristic of bevel gears is that the tooth surface is conical, and they are usually used to transmit rotational motion between non-parallel axes. When the driving gear 41 rotates to drive the driven gear 42 to rotate, due to the relatively small contact point and high pressure of the tooth surface of the bevel gear, the driven gear 42 is prone to offset or tilt during operation, resulting in uneven meshing between gears and additional wear or noise. Therefore, in order to stabilize the rotation of the driven gear 42, a stabilizing gear 44 is also rotatably installed in the rotating wheel 21. The stabilizing gear 44 is also set as a bevel gear disk. The stabilizing gear 44 is centrally symmetrically distributed with the driving gear 41. When the driving gear 41 drives the driven gear 42 to rotate, the driven gear 42 will drive the stabilizing gear 44 to rotate synchronously, and the rotation of the stabilizing gear 44 is opposite to that of the driving gear 41. The driven gear 42 is supported and stabilized by the stabilizing gear 44, so as to prevent the driven gear 42 from tilting and offsetting, evenly share the load of multiple driven gears 42, improve the meshing degree between gears, increase the transmission accuracy and reliability between gears, and reduce the influence of thermal expansion.

[0048] Of course, the driving gear 41 and the stabilizing gear 44 are not limited to be configured as bevel gear disks, and the driven gear 42 is not limited to be configured as bevel gears. Fig.10As shown, the driving gear 41 and the stabilizing gear 44 can also be configured as end face toothed discs, and correspondingly, the driven gear 42 is configured as a spur gear. The rotation of the driving gear 41 of the end face toothed disc can also drive the driven gears 42 of the five spur gears to rotate synchronously, and the stabilizing gear 44 can also support the driven gear 42 and stabilize the rotation of the driven gear 42.

[0049] Compared with other weight loss and stretching exercise equipment, the biggest advantages of the rowing machine are full-body exercise, low impact, efficient fat burning, high flexibility, and core strengthening. The rowing machine can provide comprehensive physical exercise, effectively improve cardiopulmonary function, enhance muscle strength, and help burn fat, and is suitable for all types of athletes. Whether it is weight loss, shaping, improving endurance, or strengthening muscles and core strength, the rowing machine can meet a variety of fitness needs and is an efficient and comprehensive exercise tool. At the same time, compared with the existing water resistance rowing machine, the paddle 3 in the water tank 2 is fixed, and the exercise effect can only be adjusted by adjusting the frequency of pulling the pull rope. The present invention uses a paddle 3 that can adjust the contact area with the liquid, so that the entire device improves the diversity of training. Users can adjust according to different training goals. For example, when performing endurance training, choose a smaller contact surface to reduce resistance, and when performing strength training, choose a larger contact surface to increase resistance. In this way, the training intensity can be accurately controlled and the training effect can be improved. It can also adapt to users with different physical fitness levels. For beginners, the resistance can be reduced by reducing the contact area, helping them gradually adapt to the rowing action. For athletes with high-intensity training needs, the contact area can be increased to increase resistance, thereby enhancing muscle strength and endurance. By adjusting the contact area between the paddle 3 and the liquid, the user can also avoid physical discomfort caused by excessive resistance, reduce the risk of injury, and can reasonably adjust the training intensity according to the body's feeling to avoid overtraining. This design of adjusting the contact area between the paddle 3 and the liquid can simulate different rowing environments, provide users with a more realistic water rowing experience, and can adapt to different training goals, such as enhancing endurance, increasing rowing speed, etc.

[0050] Embodiment 2

[0051] See also Figure 11-15 , which is different from the first embodiment in that:

[0052] The paddle 3 is fixedly mounted on the outer side wall of the rotating wheel 21 . The paddle 3 includes a paddle plate 31 and a telescopic plate 32 . The adjusting mechanism includes a dial wheel 43 , a sliding rod 45 and a rotating rod 46 .

[0053] like Fig.11 and Fig.12As shown, the paddle board 31 is fixedly connected to the outer wall of the rotating wheel 21, the telescopic board 32 is slidably inserted at one end of the paddle board 31, the slide bar 45 is fixedly connected to the end of the telescopic board 32 extending into the paddle board 31, and the slide bar 45 is slidably inserted in the paddle board 31 and on the outer wall of the rotating wheel 21, and the rotating rod 46 is vertically rotatably installed inside the rotating shaft 22. Fig.13 , Fig.14 and Fig.15 As shown, a slider 451 is fixedly connected to both the upper and lower sides of one end of the slide bar 45, and the slider 451 preferably adopts a cylindrical structure. A rotating disk 461 is fixedly sleeved on the outer wall of the rotating rod 46. There are two rotating disks 461, and the two rotating disks 461 are provided with sliding grooves matching the slider 451. The two sliders 451 on the slide bar 45 are slidably installed in the sliding grooves of the two rotating disks 461. The multiple sliding grooves are arranged obliquely and evenly distributed with the rotating disk 461 as the center of the circle. Two connecting rods are connected between the dial wheel 43 and the uppermost rotating disk 461. The rotating wheel 21 is consistent with the embodiment and is also provided with two arc grooves matching the connecting rods. When in use, the dial 43 is rotated to drive the slider 451 to slide in the slide groove of the turntable 461, and then drive the slide bar 45 to slide in the paddle plate 31. The sliding of the slide bar 45 drives the telescopic plate 32 to extend and retract at one end of the paddle plate 31. The longer the telescopic plate 32 extends from one end of the paddle plate 31, the longer the paddle 3 as a whole is. At this time, the contact surface between the paddle 3 and the liquid is larger, and the resistance formed is larger. On the contrary, when the telescopic plate 32 shrinks into the paddle plate 31, the overall length of the paddle 3 is reduced. At this time, the contact surface between the paddle 3 and the liquid is smaller, and the resistance formed is smaller. In summary, the paddle 3 adopts a combined structure of the paddle plate 31 and the telescopic plate 32, and the length of the paddle 3 can be controlled by the adjustment mechanism, thereby adjusting the contact area between the paddle 3 and the liquid.

[0054] like Fig.12 and Fig.13 As shown, the telescopic plate 32 is provided with two slide bars 45. At this time, four rotating disks 461 are fixedly sleeved on the rotating rod 46. By providing two slide bars 45, the telescopic plate 32 can be driven to slide in the paddle plate 31 more stably. In theory, the more slide bars 45 there are, the higher the stability of controlling the sliding of the telescopic plate 32. Although the embodiments of the present invention have been shown and described, it can be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
