Description

Technical Field

[0001] The invention relates to the technical field of fitness equipment, in particular to a double-resistance system water-resistance type rowing machine. Background Art

[0002] The rowing machine is a fitness device that simulates rowing. The rowing machine moves rowing from water to land, thus breaking the deadlock of "no water, no rowing". Rowing can make the upper limbs, lower limbs, waist, abdomen, and back muscles complete complete contraction and extension exercises, achieving the effect of exercising the muscles of the whole body. Due to the unique function and structure of the rowing machine, it has gradually become a new favorite of the fitness public and has been loved by people in the market. It is listed as one of the top ten most popular fitness equipment in the world. As a type of rowing machine, the water resistance rowing machine is very popular because it simulates the real rowing method, creates the visual, sound and feeling effects of real rowing, and allows people to experience realistic and gradual rowing exercises.

[0003] The water resistance rowing machine mainly provides motion resistance through a water resistance water tank. The existing water resistance water tank is equipped with a paddle. The water tank is filled with water and the paddle is immersed in the water. The paddle is linked to the transmission mechanism outside the water tank through a rotating shaft, and the control mechanism (for example, a pulling type or a rowing rod type control mechanism) is linked to the transmission mechanism. When the exerciser exercises by applying force to operate the control mechanism, the control mechanism drives the paddle to rotate through the transmission mechanism, and the paddle moves in the water, forming resistance.

[0004] At present, water resistance rowing machines on the market are usually only provided with one set of resistance system, that is, a water tank is generally provided on the rowing machine, a single transmission mechanism is provided on the water tank, and an operating mechanism is provided to be linked with the transmission mechanism of the water tank. By providing left and right hand gripping parts on the operating mechanism (for example, a horizontal bar type gripping bar or a triangular gripping part), the exerciser's hands can operate the operating mechanism at the same time, and both arms can be exercised. However, this method makes the exercise of both hands be carried out synchronously, and cannot be separated and exercised individually according to needs, and the exercise method is too single and inflexible.

[0005] The Chinese utility model patent with application number CN201921385137.8 and authorization announcement date 20200814 discloses a water-resistance rowing machine with adjustable resistance, which includes a main frame, a seat cushion, an operating mechanism, a transmission mechanism and a sealed water tank; the seat cushion is slidably mounted on the main frame; the water tank is in the shape of a flat barrel, the water tank is equipped with paddles and filled with liquid that leaves a certain space in the inner cavity of the water tank; the paddles are linked to the transmission mechanism outside the water tank through a rotating shaft, and the operating mechanism is linked to the transmission mechanism; the rowing machine also includes a mounting bracket and a supporting component, the water tank is fixed in the mounting bracket, the top end of the mounting bracket is rotatably connected to the main frame, and the supporting component is connected between the mounting bracket and the main frame. This utility model can utilize the water tank to tilt when the mounting bracket rotates, thereby increasing the rotation resistance of the blades. However, this technical solution also has only one set of resistance system. When using it for exercise, the exercise of both hands is carried out simultaneously, and cannot be exercised separately according to needs. In addition, the exercise method is limited to forward pulling and backward pushing operations, and the method is single and inflexible. Summary of the invention

[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments; the technical features designed in different implementation modes of the present invention described below can be combined with each other as long as they do not conflict with each other; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0057] In the description of the present invention, it should be noted that all terms used in the present invention (including technical terms and scientific terms) have the same meanings as those generally understood by ordinary technicians in the field to which the present invention belongs, and cannot be understood as limiting the present invention; it should be further understood that the terms used in the present invention should be understood to have the same meanings as these terms in the context of this specification and in the relevant fields, and should not be understood in an idealized or overly formal sense, unless explicitly defined in the present invention.

[0058] The present invention provides Figure 1-14 A dual resistance system water resistance type rowing machine shown in the embodiment includes a main frame 20, a seat cushion 30, a first resistance system and a second resistance system; the first resistance system and the second resistance system both include:

[0059] A water resistance type water tank 110, in which a rotatable water paddle 112 is provided;

[0060] A transmission mechanism 120, which is connected to the water paddle 112 via a rotating shaft to drive the water paddle 112 to rotate;

[0061] A manipulation mechanism 130, which is linked with the transmission mechanism 120 to drive the transmission mechanism 120 to move;

[0062] Each operating mechanism 130 includes a traction belt 131 and a gripping portion 132. One end of the traction belt 131 is linked to the transmission mechanism 120, and the other end is fixedly connected to the gripping portion 132. The first resistance system and the gripping portion 132 of the first resistance system are respectively used to provide gripping parts for the left hand and right hand of the exerciser.

[0063] Specifically, Figure 1-14As shown, the present invention adopts a dual resistance system (a first resistance system and a second resistance system), each resistance system includes a water resistance type water tank 110, a transmission mechanism 120 and a control mechanism 130, that is, the first resistance system includes a first water resistance type water tank 110a, a first transmission mechanism 120a and a first control mechanism 130a, and the second resistance system includes a second water resistance type water tank 110b, a second transmission mechanism 120b and a second control mechanism 130b; when the exerciser uses it, the hand holds the gripping part 132 of the control mechanism 130 to exercise, and the gripping part 132 pulls the traction belt 131, and the traction belt 131 drives the transmission mechanism 120 linked with it to rotate, thereby driving the water paddle 112 connected to the rotating shaft of the transmission mechanism 120 to rotate, the water resistance type water tank 110 is filled with water, and the water paddle 112 rotates in the water to form resistance, thereby causing resistance to the arm movement of the exerciser, and realizing a simulated rowing experience;

[0064] By setting up a dual resistance system (a first resistance system and a second resistance system), the two resistance systems operate completely independently. When the left and right arms of the exerciser respectively hold the gripping parts 132 of the first operating mechanism 130a and the second operating mechanism 130b to exercise, the left and right arms can be exercised separately. The user can adjust the exercise frequency and exercise intensity of different arms according to needs, and the exercise method is more flexible and diverse, which is convenient for people to use and effectively improves its market competitiveness.

[0065] Among them, the water resistance type water tank 110 and the transmission mechanism 120 are prior art, and their working principles are not repeated; preferably, in this embodiment, the transmission mechanism 120300 is an existing scroll rotation reset mechanism with a transmission function (application number is CN202010260577.1, and the applicant is Xiamen Derby Health Technology Co., Ltd.'s Chinese invention patent application discloses the mechanism), and the scroll rotation reset mechanism includes a transmission shaft 121, a rotating wheel 122 and a rebound portion 123, and the scroll rotation reset mechanism One end of the transmission shaft 121 is connected to the water paddle 112, and the other end of the transmission shaft 121 is connected to the rotating disc 122. The rotating disc 122 is linked to the traction belt 131 of the operating mechanism 130, so that the operating mechanism 130 drives the rotating disc 122 to rotate. For example, in this embodiment, a webbing traction part is wrapped around the rotating disc 122, and the webbing is connected to the traction belt 131 (a steel wire rope is used as the traction belt 131). The movement of the traction belt 131 drives the webbing to move, thereby driving the rotating disc 122 to rotate, thereby driving the rotating shaft and the water paddle 112 to rotate.

[0066] It should be noted that, based on the above design concept, those skilled in the art may also adopt other types of transmission mechanisms 120, which are linked to the operating mechanism 130 through the transmission mechanism 120, so that the operating mechanism 130 drives the water paddle 112 to rotate through the transmission mechanism 120, including but not limited to the above-mentioned transmission mechanism 120 type.

[0067] Preferably, the left and right sides of the front part of the main frame 20 are respectively provided with a multi-directional adjustment mechanism 250; the multi-directional adjustment mechanism 250 includes a guide wheel frame 251 and a guide wheel 252 mounted in the guide wheel frame 251; the traction belt 131 is arranged on the guide wheel 252, and the guide wheel frame 251 is rotatably connected with the main frame 20, so that when the traction belt 131 is pulled to the left and right sides, the traction belt 131 drives the guide wheel frame 251 to rotate. Further preferably, as Figure 5 As shown, the guide wheel frame 251 is a U-shaped double-plate clamping structure, and the guide wheel 252 is arranged in the middle of the double-plate clamping; and the guide wheel frame 251 is rotatably connected to the axis of the guide wheel 252.

[0068] Multi-directional adjustment mechanisms 250 are respectively arranged on the left and right sides of the front part of the main frame 20 of the water resistance type rowing machine, and two traction belts 131 are respectively arranged on the two multi-directional adjustment mechanisms 250. When using the water resistance type rowing machine, the exerciser holds the gripping part 132 and moves it to the left and right sides, pulling the traction belt 131 to the left and right sides. The traction belt 131 applies force to the multi-directional adjustment mechanism 250 to drive the guide wheel frame 251 to rotate; by setting the guide wheel frame 251 to rotate freely, the traction belt 131 can change the traction direction, so that the movement direction of the gripping part 132 connected to the traction belt 131 can be adjusted, and the exerciser can not only perform actions such as pulling the pull rope forward and backward, but also perform bilateral chest expansion exercises, unilateral chest expansion exercises, etc.; the existing traditional water resistance type rowing movement mode is limited to the front and rear side traction action. Compared with this, the water resistance type rowing machine provided has more flexible and diverse movement modes and diversified functions.

[0069] Among them, in this embodiment, the guide wheel frame 251 is provided with an axle nail, and the main frame 20 is provided with an axle nail mounting frame, the axle nail frame is mounted on the mounting frame and is rotatably connected with the mounting frame, and the guide wheel frame 251 is freely rotated by rotating along its axis through the axle nail; according to the above design concept, those skilled in the art may also adopt other rotational connection methods to enable the two guide wheel frames 251 to be respectively rotationally connected to the left and right sides of the front of the main frame 20, including but not limited to the above-mentioned rotational connection methods.

[0071] Since the upper guide wheel 2521 and the lower guide wheel 2522 are mounted on the guide wheel frame 251, and the two are arranged adjacent to each other, when in use, the traction belt 131 passes between the upper guide wheel 2521 and the lower guide wheel 2522. When the traction belt 131 is pulled downward, the lower guide wheel 2522 is subjected to force, and the lower guide limits its downward movement. When the traction belt 131 is pulled upward, the upper guide wheel 2521 is subjected to force, and the upper guide limits its upward movement. 521 and the lower guide wheel 2522 are arranged, when the exerciser uses the water resistance rowing machine, he can raise and lower his arms (for example, raising both arms sideways or horizontally, raising one arm sideways or horizontally, lowering both arms sideways or horizontally, lowering one arm sideways or horizontally, etc.). In addition, since the multi-directional adjustment mechanism 250 can rotate freely, when the exerciser uses it, the left and right movements and the up and down movements can also be combined synchronously, such as raising both arms sideways and chest expansion movements, etc., and the exercise methods are more flexible and diverse.

The bracket 240 is arranged above the front end of the transverse beam 210 to facilitate the installation of components such as the multi-directional adjustment mechanism 250 and the foot pedal 40. At the same time, the bracket 240 can also be used to install a display panel or a flat-panel display, a mobile phone and other electronic products, which is convenient for people to use.

When in use, after the traction belt 131 is led out from the water resistance type water tank 110, it is guided by the rear guide pulley 231 and the front guide pulley 221 in turn, and is finally arranged on the multi-directional adjustment mechanism 250; both resistance systems are equipped with a front guide pulley 221 and a rear guide pulley 231 to position and guide the traction belt 131, and the stretching and traction of the traction belt 131 is smoother, thereby improving the user experience.

[0077] Preferably, a movable roller is provided at the rear end of the rear support seat assembly 230, and the movable roller is mounted on a roller frame, one end of the roller frame is rotatably connected to the axis of the movable roller, and the other end of the roller frame is rotatably connected to the rear support seat assembly 230; when the rowing machine is upright, the movable roller can touch the ground and roll, and when the rowing machine is placed horizontally, the movable roller is located at the rear end of the rear support seat assembly 230, that is, located on the side of the supporting foot of the rear support seat assembly 230; the movable roller is provided to facilitate the user to move the rowing machine.

[0079] When in use, the relative positions of the adjusting slide plate 420 and the fixing plate 410 are adjusted according to the foot size of the user. After being adjusted into place, the positioning pin block 411 on the fixing plate 410 is inserted into the adjusting hole 421 of the adjusting slide plate 420 to fix the positions of the two. The above design makes it easy for people with different foot sizes to use.

[0080] Preferably, a foot rest 422 for preventing the foot from sliding downward is provided at the tail of the adjusting slide plate 420. The foot rest 422 is provided to prevent the foot of the user from sliding downward during fitness.

[0081] Preferably, an indicator mark 423 is provided on the adjusting slide plate 420. The indicator mark 423 is provided to indicate the fixed position of the adjusting slide plate 420, so as to indicate the foot size to which the foot pedal 40 is applicable.

[0082] Preferably, a foot strap 430 for fixing the foot on the foot pedal 40 is provided at the front of the foot pedal 40. When in use, the foot strap 430 is used to fix the user's foot on the foot pedal 40 to prevent the foot from sliding.

[0085] Specifically, a housing groove 1113 is concavely provided on the water tank housing 111, and the transmission mechanism 120 is embedded in the housing groove 1113. The transmission mechanism 120 embedded in the groove is connected to the water paddle 112, so that the transmission mechanism 120 drives the water paddle 112 to rotate. At the same time, the paddle disc 1121 of the water paddle 112 installed in the water tank housing 111 adopts a flat disc structure, and the paddle blades 1122 are arranged on the outer periphery of the paddle disc 1121. By providing the raised paddle blades 1122 on the outer periphery of the paddle disc 1121, water resistance can be effectively generated when the water paddle 112 rotates, thereby ensuring the function of the water resistance type water tank 110 to provide resistance. Moreover, the middle position of the paddle disc 1121 is a flat disc structure, so that there is a certain amount of redundant space in the middle position, which provides installation space for the housing groove 1113 concavely provided in the water tank housing 111. The flat disc-shaped water paddle 112 cooperates with the water tank shell 111 provided with a groove, so that the space occupied by the water tank is reduced as a whole.

[0088] When the angle between the blade surface of the paddle 1122 and the rotation direction of the paddle 1122 is 90°, the water resistance is the largest, which can effectively increase the water resistance. When people use the water resistance type water tank 110, the water resistance is obvious and the exercise effect is good. The angle between the blade surface of the paddle 1122 and the rotation direction of the paddle 1122 is 90°. In this embodiment, the paddle disc 1121 adopts a disc-type structure, and the blade surface of the paddle 1122 is arranged along the radial direction of the paddle disc 1121, that is, the blade surface of the paddle 1122 is perpendicular to the tangent of its position.

[0089] Preferably, a water-facing groove 1123 is provided on the water-facing surface of the blade 1122. By providing the water-facing groove 1123, the contact area between the water-facing surface of the blade 1122 and the water is increased, and the water resistance is increased, so that when people use the water resistance type water tank 110, the water resistance is obvious and the exercise effect is good.

[0090] Preferably, a guide groove 1124 is provided between two spaced-apart blades 1122 on the paddle disc 1121 , and the guide groove 1124 is arranged along the rotation path of the blade 1122 .

[0091] A guide groove 1124 is provided on the paddle disc 1121. When the water paddle 112 rotates, the water flow between the two paddle blades 1122 is guided by the guide groove 1124. The water flow hits the water-facing surface of the paddle blade 1122 along the guide groove 1124, which can effectively increase the water resistance, so that when people use the water resistance type water tank 110, the water resistance is obvious and the exercise effect is good. In this embodiment, the paddle disc 1121 adopts a disc structure, the paddle blade 1122 is arranged along the outer circumference of the paddle disc 1121, the rotation path of the paddle blade 1122 of the water paddle 112 is circular, and the guide groove 1124 between the two paddle blades 1122 is arranged in an arc shape along the rotation path.

[0092] Preferably, a flow opening 1125 is provided in the middle of the paddle disc 1121 to allow water to flow above and below the paddle disc 1121. The middle of the paddle disc 1121 is a flat disc structure. When the paddle disc 1121 rotates, the water flow in the middle cannot collide with the water-facing surface of the blade 1122 to generate greater resistance. By providing the flow opening 1125 in the middle of the paddle disc 1121, water flows above and below the paddle disc 1121, thereby increasing turbulent resistance.

[0093] Preferably, the paddle disc 1121 is a disc structure, and the paddle blades 1122 are arranged at equal angles along the outer circumference of the paddle disc 1121. The paddle disc 1121 is a disc structure, and the paddle blades 1122 are arranged at equal angles along the outer circumference of the paddle disc 1121. In this way, the effect of water flow hitting the blade surface of the paddle blade 1122 is better, increasing the water resistance.
