Description

Technical Field

[0001] This application relates to the field of fitness equipment technology, and in particular to a water resistance double-barrel rowing machine. Background Technology

[0002] A rowing machine, also known as a rowing machine, rowing boat machine, or rowing paddle machine, is a fitness device that simulates rowing on land. Existing rowing machines can be categorized according to the method of providing resistance: air resistance rowing machines, magnetic resistance rowing machines, friction resistance rowing machines, hydraulic resistance rowing machines, and water resistance rowing machines.

[0003] Among them, the water resistance rowing machine has the best simulation technology, which allows people to experience the sight, sound and feeling of real rowing. During exercise, the resistance of the liquid and the change of the speed of the wheel are used to exercise the muscles of the body in a short period of time. It has a good effect on strengthening the muscles of the legs, waist, upper limbs, chest and back. Each time a complete contraction and extension is completed, the muscles of the whole body can achieve the effect of aerobic exercise.

[0004] Currently, water resistance rowing machines include a base frame, a water tank, a guide rail, a sliding seat, a foot support surface, a rope, and a rope winding mechanism. The water tank is fixed on the support frame, and a rotating shaft perpendicular to the ground and a rotating paddle connected to the shaft are pivotally connected inside the water tank. The guide rail is set on the base frame and extends towards one side of the base frame. The sliding seat slides on the guide rail. The foot support surface is set on the base frame and located between the water tank and the guide rail. The rope winding mechanism includes a winding disc, which is set on the rotating shaft and can rotate synchronously with it. The rope is wound on the winding disc, and a handle is connected to the outer end of the rope. An elastic reset structure is provided between the winding disc and the base frame to reset the winding disc.

[0005] When in use, the user sits on the sliding seat with their feet resting on the foot support surface. They exercise by pulling the handle. Pulling the handle outward causes the rope winding mechanism to rotate, which in turn drives the rotating paddle to rotate. Under the resistance of the water tank and the elastic resistance of the elastic reset structure, a rowing-style exercise is performed. When the rope needs to be reset, the elastic reset structure causes the winding disc to rotate in the opposite direction to wind the rope again, so that the rope can be stretched again.

[0006] Regarding the aforementioned technologies, existing water resistance rowing machines generally have only one water tank (bucket), which is usually located on one side of the rowing machine (such as the left or right side). When rowing, pulling the paddle inside the water tank to rotate generates resistance, which leads to uneven distribution of weight and resistance on the left and right sides of the machine body, and therefore needs to be improved. Utility Model Content

[0007] In order to improve the uniformity of force distribution during the use of the rowing machine, this application provides a water resistance double-barrel rowing machine.

[0008] The water resistance double-barrel rowing machine provided in this application adopts the following technical solution:

[0009] A water-resistance double-barrel rowing machine includes a frame, a guide rail, a slide, a foot support surface, a first water tank, a second water tank, a connecting shaft, and a winding assembly. The guide rail is mounted on the frame, the slide is slidably connected to the guide rail, and the foot support surface is mounted on the frame and is used for foot support.

[0010] The first water tank and the second water tank are symmetrically arranged on the frame, and each is equipped with a rotating blade inside. The two rotating blades are connected by the connecting shaft.

[0011] The winding assembly includes a handle, a winding reel, and a pull-back mechanism. The winding reel is rotatably connected to the frame and connected to the connecting shaft, and is used to drive the connecting shaft to rotate. The handle is located on the frame and connected to the winding reel via a rope, and is used to pull the winding reel to rotate. The pull-back mechanism is coaxially arranged with the winding reel and is used to control the winding reel to return to its original position.

[0012] By employing the above technical solution, during use, the user sits on the slide with their feet resting on the foot support surface, and exercises by pulling the handles with both hands. Pulling the handles outward causes the winding disc to rotate, which in turn drives the rotating paddle blades to rotate, creating a rowing-like exercise under the resistance of the liquid in the two water tanks and the elastic resistance of the pullback device. When the rope needs to return to its original position, the elastic restoring force of the pullback device causes the winding disc to rotate in the opposite direction to wind the rope again, allowing for another rope lengthening exercise.

[0013] By symmetrically setting the first and second water tanks, which are located on the left and right sides of the rowing machine respectively, the weight is evenly distributed. When rowing, the rotating blades in the water tanks on both sides generate resistance at the same time, so that the frame is balanced by the force, reducing the risk of deformation and improving the stability of the equipment. Even in high-intensity training, it can remain stable and reduce the safety hazards caused by shaking.

[0014] Preferably, the assembly also includes a bearing and a sealing ring seat. The connecting shaft is connected to the first water tank and the second water tank via the bearing. The sealing ring seat is provided on both the first water tank and the second water tank, and the sealing ring seat is located on the periphery of the bearing.

[0015] By adopting the above technical solution, when the connecting shaft rotates, the presence of the bearing allows the connecting shaft to rotate relative to the first and second water tanks. The presence of the sealing ring seat improves the sealing performance at the bearing mounting location, preventing water leakage from inside the water tanks.

[0016] Preferably, the first water tank and the second water tank are connected to each other by a connecting pipe, the connecting pipe being located at the end of the first water tank closer to the ground; the second water tank has a water inlet through which a water inlet is provided, and the water inlet is provided with a water inlet plug.

[0017] By adopting the above technical solution, the connecting pipe connects the first and second water tanks, ensuring that the water volume in both tanks remains consistent at all times, thereby guaranteeing the rotational balance of the left and right paddles and the consistency of resistance. The presence of the inlet plug allows the user to easily inject an appropriate volume of water into the second water tank, ensuring the rowing machine's training effect.

[0018] Preferably, it also includes a mesh cover, which is arc-shaped and located between the first water tank and the second water tank.

[0019] By adopting the above technical solution, the net covers the area between the first and second water tanks, making it appear as if there is only one water tank, which is a concealed double-bucket design.

[0020] Preferably, the foot support surface is provided with a plurality of raised strips and raised dots.

[0021] By adopting the above technical solution, the design of the raised strips and raised dots can make the foot support surface uneven. When the user's foot comes into contact with the foot support surface for exercise, it can increase the static friction of contact and improve the safety of exercise.

[0022] Preferably, the guide rail is provided with a plurality of limiting pads, the limiting pads are located on the moving path of the slide, the slide is located between each of the limiting pads, and the limiting pads are used to limit the moving length of the slide.

[0023] By adopting the above technical solution, the presence of the limiting pad can form a rigid blocking boundary, ensuring that the slide always moves within the effective range of the guide rail, avoiding the slide from leaving the guide rail due to excessive force or loss of control, which could cause damage to the equipment or safety accidents such as user falls or collisions.

[0024] Preferably, it also includes front leg tubes and rear leg tubes, which are respectively connected to both ends of the frame and are used to support the machine on the ground.

[0025] By adopting the above technical solution, the front and rear leg tubes are supported on the ground together, so that the entire rowing machine can be placed stably on the ground.

[0026] Preferably, a pair of rollers are rotatably connected to the front leg tube; a pair of adjustable foot pads are connected to the side of the rear leg tube facing the ground.

[0027] By adopting the above technical solution, users can adjust the rowing machine's height, balance, and stability by adjusting the foot pads. The structure of the adjusting foot pads is existing technology, such as a metal rod that runs vertically through the supporting rear foot tubes, with threads engraved on the surface. Some high-end products use nylon or stainless steel for corrosion resistance. Adjustment is achieved by rotating a screw (or using a knob or wrench) to change the extension length.

[0028] When the rowing machine needs to be moved, the user can slightly lift the side with the rear leg tubes so that the rollers on the front leg tubes contact the ground, and then push the entire rowing machine. The rollers will roll on the ground, changing the position of the rowing machine. Compared to relying on two people to move the rowing machine, the rolling method reduces the difficulty of moving the rowing machine, achieving a labor-saving effect, and can be done by one person.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] (1) By setting up a first water tank and a second water tank, the two symmetrical water tanks are located on the left and right sides of the rowing machine, respectively. The weight is evenly distributed. When rowing, the rotating blades in the water tanks on both sides generate resistance at the same time, so that the frame is balanced by force, reducing the risk of deformation and improving the stability of the equipment.

[0031] (2) By setting up a net cover, the area between the first water tank and the second water tank is covered up, so that it looks like there is only one water tank from the outside. It is a concealed double water tank design.

[0032] (3) By setting a limiting pad, the existence of the limiting pad can form a rigid blocking boundary, ensuring that the slide always moves within the effective range of the guide rail, thus improving the safety of use. Attached Figure Description

[0043] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0044] This application discloses a water-resistance double-barrel rowing device. (Refer to...) Figures 1 to 3The water resistance double-barrel rowing machine includes a frame 1, a guide rail 2, a slide 3, a foot support surface 4, a first water tank 5, a second water tank 6, a connecting shaft 7, and a winding assembly 8. The frame 1 serves as the carrier, with a front foot tube 16 and a rear foot tube 17 fixedly connected to both ends, both supporting the machine on the ground. The guide rail 2 is fixedly connected to the frame 1 and located between the front foot tube 16 and the rear foot tube 17, with the slide 3 slidably connected to the guide rail 2. The foot support surface 4 is fixedly connected to the frame 1 and close to the front foot tube 16, providing support for the feet. Several protrusions 9 and protrusions 10 are fixedly connected to the foot support surface 4. The design of the protrusions 9 and protrusions 10 makes the foot support surface 4 uneven, increasing the friction between the foot support surface 4 and the user's feet, thereby improving the safety of the exercise.

[0045] Combination Figure 4 The first water tank 5 and the second water tank 6 are located on the same side as the front foot pipe 16. The first water tank 5 and the second water tank 6 are symmetrically mounted on the frame 1, and each contains a rotating blade 12. The two rotating blades 12 are connected by a connecting shaft 7. In this embodiment, the first water tank 5 and the second water tank 6 are interconnected by a connecting pipe 11. The connecting pipe 11 is located at the end of the first water tank 5 closest to the ground to facilitate water flow between the two tanks. The connecting pipe 11 connects the first water tank 5 and the second water tank 6, ensuring that the water volume in both tanks remains consistent, thereby ensuring the rotational balance and consistent resistance of the left and right blades. A water inlet is provided through the second water tank 6, and a water inlet plug 21 made of rubber is installed at the inlet. The water inlet plug 21 allows the user to easily inject an appropriate volume of water into the second water tank 6. When filling with water, the water inlet plug 21 is first removed, and then replaced after filling.

[0046] The winding assembly 8 includes a handle 81, a winding reel 82, and a return puller 83. The winding reel 82 is rotatably connected to the frame 1 and connected to the connecting shaft 7. The winding reel 82 drives the connecting shaft 7 to rotate. In this embodiment, the winding reel 82 is connected to the connecting shaft 7 via a timing belt. The handle 81 is mounted on the frame 1 and connected to the winding reel 82 via a rope. The handle 81 is used to pull the winding reel 82 to rotate. The return puller 83 is coaxially arranged with the winding reel 82 and is used to control the return of the winding reel 82.

[0047] In use, the user sits on the slide seat 3 with both feet resting on the foot support surface 4, and exercises by pulling the handles 81. Pulling the handles 81 outward causes the winding disc 82 to rotate, which in turn causes the rotating paddle blades 12 to rotate, resulting in a rowing-like exercise under the resistance of the liquid in the two water tanks and the elastic resistance of the pullback device 83. When the rope needs to return to its original position, the elastic restoring force of the pullback device 83 causes the winding disc 82 to rotate in the opposite direction to wind the rope again, allowing for another rope lengthening exercise.

[0048] Combination Figure 4 and Figure 5 Specifically, the connecting shaft 7 is connected to the first water tank 5 and the second water tank 6 via bearings 13. Both the first and second water tanks 5 and 6 are fixedly equipped with sealing ring seats 14, which are located around the bearings 13. The sealing ring seats 14 improve the sealing at the bearing 13's mounting position, preventing water leakage from the tanks. A mesh cover 20 is also installed between the first and second water tanks 5 and 6. The mesh cover 20 is arc-shaped, concealing the area between the first and second water tanks 5 and 6, making it appear as if there is only one water tank – a concealed double-tank design. Several limiting pads 15 are fixedly connected to the guide rail 2. These limiting pads 15 are located along the movement path of the slide 3, with the slide 3 positioned between them. The limiting pads 15 restrict the movement range of the slide 3. The presence of the limiting pad 15 can form a rigid blocking boundary, ensuring that the slide 3 always moves within the effective range of the guide rail 2, and preventing the slide 3 from leaving the guide rail 2 due to excessive force or loss of control, which could cause damage to the equipment or safety accidents such as user falls or bumps.

[0049] In addition, a pair of rollers 18 are rotatably connected to the front leg tube 16, with the axles of the two rollers 18 being parallel to each other. A pair of adjusting feet 19 are also installed on the ground-facing side of the rear leg tube 17; the adjusting feet 19 are screws. Users can adjust the rowing machine's height, balance, and stability by adjusting the feet 19. Adjustment is achieved by rotating the screws to change the extension length.

[0050] When the rowing machine needs to be moved, the user can slightly lift the side with the rear leg tube 17 so that the roller 18 of the front leg tube 16 contacts the ground, and then push the entire rowing machine. The roller 18 rolls on the ground, thus changing the position of the rowing machine. Compared to relying on two people to move the rowing machine, the rolling method of the roller 18 reduces the difficulty of moving the rowing machine, achieving the effect of saving effort, and can be done by one person.

[0051] The implementation principle of the water resistance double-barrel rowing machine in this application embodiment is as follows: by symmetrically setting the first water tank 5 and the second water tank 6, the two symmetrical water tanks are located on the left and right sides of the rowing machine respectively, and the weight is evenly distributed. When rowing, the rotating paddle blades 12 in the water tanks on both sides generate resistance at the same time, so that the frame 1 is balanced by the force, reducing the risk of deformation, improving the stability of the equipment, and maintaining stability even in high-intensity training, reducing the safety hazards caused by shaking.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
