Description

Technical Field

[0001] The utility model relates to the technical field of water resistance box structures, in particular to an improved stepless resistance adjustment structure for a water resistance box. Background Art

[0002] As an advanced resistance generation mechanism, the water resistance system has been widely used in the field of fitness equipment, especially in rowing machines (also known as rowing ergometers, rowing boats, etc.). Such systems precisely control resistance by adjusting the water volume and the rotational speed of the paddle or flywheel, thereby providing an exercise effect close to the real rowing experience. Due to its unique simulation technology, the water resistance rowing machine can reproduce the visual, auditory, and tactile sensations of rowing in water and has quickly gained market favor.

[0003] The advantages of the water resistance system are that it can instantaneously adjust the resistance according to user needs. Through the dynamic changes of the liquid and the regulation of the runner speed, it can effectively stimulate more than 80% of the muscle groups in the whole body, especially strengthening the muscles of the legs, waist, upper limbs, chest, and back. Each complete action cycle can ensure that the muscles receive comprehensive aerobic exercise, improving cardiopulmonary function and endurance.

[0004] However, despite the significant fitness benefits brought by the water resistance system, there are still certain problems in the resistance adjustment of the existing water resistance system:

[0005] 1. If the traditional water resistance system needs to adjust the resistance level, it usually relies on increasing or decreasing the liquid volume in the container. This physical operation is both time-consuming and difficult to implement during exercise, limiting the user's ability to flexibly adjust the resistance according to personal status or training goals.

[0006] 2. The existing systems often fail to achieve smooth stepless adjustment within a certain range, which means that in some resistance intervals, users may encounter problems with discontinuous adjustment, affecting the exercise experience.

[0007] In view of this, the inventor has specifically designed an improved stepless resistance adjustment structure for a water resistance box, and this case is thus generated. Content of the Utility Model

[0008] In order to solve the above problems, the technical solution of the utility model is as follows:

[0009] An improved stepless resistance adjustment structure for a water resistance box, comprising:

[0010] The main body of the water tank is provided with a water storage bucket inside, which divides the inner space of the main body of the water tank into a water storage cavity inside the water storage bucket and a resistance cavity between the water storage bucket and the main body of the water tank. A water inlet channel at a high position is provided on the side wall of the water storage bucket. The bottom of the water storage bucket protrudes upward to form an overflow wall that intrudes into the water outlet cavity. An overflow channel communicating with the resistance cavity is formed inside the overflow wall. An overflow port is provided through the side wall of the overflow wall and located in the water outlet cavity.

[0011] The adjusting member is rotatably arranged inside the water storage cavity and on one side of the overflow wall, and includes a shielding structure for shielding the overflow port. A liquid overflow port for the liquid in the water storage cavity to flow out is formed between the top of the shielding structure and the overflow port.

[0012] Wherein, the shielding structure is configured such that the height of the lowest position of the overflow port changes linearly as its main body rotates.

[0013] Preferably, the overflow wall includes a pair of side walls arranged relatively parallel to each other and a U-shaped wall connected between the same sides of the two side walls. The overflow ports are formed on the sides of the two side walls away from the U-shaped wall.

[0014] Preferably, the center of the U-shaped wall is opposite to the center position of the water storage bucket to form a through-axis channel penetrating up and down.

[0015] Preferably, the tops of the U-shaped wall and the side walls extend to a position flush with the upper edge of the water storage bucket.

[0016] Preferably, the adjusting member further includes a connecting shaft and a knob arranged at the top of the connecting shaft to control the rotation of the connecting shaft. The shielding structure is arranged around the outer peripheral side of the connecting shaft.

[0017] Preferably, the shielding structure includes a sector-shaped bottom plate and a shielding plate extending upward along the circumferential edge of the bottom plate. The top end of the shielding plate is in a spiral shape with a linearly increasing height, so that the shielding plates at different positions enclose overflow edges with different height positions with the overflow port.

[0018] Preferably, a horizontal section with a consistent height is provided at the highest position of the shielding plate, so that the shielding plate corresponding to the horizontal section forms an initial end with the largest overlapping shielding area with the overflow port.

[0019] Preferably, a connecting piece is provided between the shielding plate and the connecting shaft, and the highest position of any one of the connecting pieces is consistent with the top end of the shielding plate.

[0020] Preferably, a rotating convex point is protruded on the inner bottom of the water storage bucket and on one side of the overflow port, and a rotating hole cooperating with the rotating convex point is provided at the lower end of the rotating shaft.

[0021] Preferably, the bottom plate is in a D shape with a central angle of 180°.

[0022] The utility model overcomes the deficiencies of traditional water resistance systems in terms of resistance adjustment, achieving fast and smooth stepless adjustment, which greatly improves the user experience and exercise effect. Specifically, its main advantages include:

[0023] 1. By rotating the adjustment member to control the height of the overflow port, there is no need to manually add or subtract the water volume in the water tank, enabling users to instantaneously adjust the resistance during exercise, meeting different intensity requirements, and improving the flexibility and efficiency of exercise.

[0024] 2. The special design of the shielding structure causes the height of the overflow port to change linearly, achieving continuous and smooth adjustment of resistance within a certain range, avoiding the discontinuous adjustment phenomenon that may occur in traditional systems, and ensuring the smoothness and comfort of the exercise process.

[0025] In summary, the utility model not only solves the problems existing in the existing water resistance systems, such as inconvenient adjustment, lack of positioning, and limitations of stepless adjustment, but also improves the convenience, accuracy, and safety of resistance adjustment, providing users with a more efficient and personalized fitness solution.

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0039] Please refer to Figures 1 to 8 , which is an improved stepless resistance adjustment structure of a water resistance box as the best embodiment of the present utility model, including:

[0040] A water tank main body 10, inside which there is a water storage bucket 20 to divide the inner space of the water tank main body 10 into a water storage cavity 30 inside the water storage bucket 20 and a resistance cavity 40 between the water storage bucket 20 and the water tank main body 10. The side wall 63 of the water storage bucket 20 is provided with a water inlet channel 14 at a high position. The bottom of the water storage bucket 20 protrudes upward to form an overflow wall 60 that intrudes into the water outlet cavity. An overflow channel 61 communicating with the resistance cavity 40 is formed inside the overflow wall 60. The part of the side wall 63 of the overflow wall 60 located in the water outlet cavity is provided with an overflow port 62 in a penetrating manner;

[0041] Specifically, as shown in Figure 1 、 2 , in this embodiment, the water tank main body 10 is a split cylindrical shape, including a lower box body 12 and an upper box body 11. An annular connecting edge 13 is arranged around the center of the inner bottom of the upper box body 11. The connecting edge 13 is adapted to the outer diameter of the top of the water storage bucket 20 and is provided with a plurality of locking holes (not shown in the figure) for installing bolts. The water storage bucket 20 is a cylindrical shape with an open upper end, and a plurality of locking columns 21 corresponding to the locking holes one by one are arranged around its inner wall, and are fixedly locked on the connecting edge 13 through bolts.

[0042] Particularly, as shown in Figure 2As shown, there is at least a partial notch along the connection 13 so that a gap is formed between the top of the water storage bucket 20 and the inner side wall of the upper box body 11, and this gap is the water inlet channel 14.

[0043] In addition, as Figure 3 , 4 shown, in this embodiment, the overflow port 62 is formed by arranging an overflow wall 60 in the water storage cavity 30. A water storage space for containing liquid is formed between the outer side wall surface of the overflow wall 60 and the water storage cavity 30. An opening is formed on the overflow wall 60 so that the liquid in the water storage space can flow along the opening to the overflow channel 61, and finally enter the resistance cavity 40 through the bottom of the overflow channel 61, thereby forming an overflow path for the liquid in the water storage cavity 30, so that the corresponding liquid can smoothly enter the resistance cavity 40 to cooperate with the paddle 80 and generate resistance as the paddle 80 rotates.

[0044] It further includes an adjusting member 50. The adjusting member 50 is rotatably arranged in the water storage cavity 30 and is located on one side of the overflow wall 60. It includes a shielding structure 70 for shielding the overflow port 62. An overflow edge for the liquid in the water storage cavity 30 to flow out is formed between the top of the shielding structure 70 and the overflow port 62. An installation opening (not marked in the figure) reserved specifically for the adjusting member 50 is provided on the upper box body 11;

[0045] Among them, the shielding structure 70 is configured such that as its main body rotates, the height of the lowest position of the overflow port 62 changes linearly.

[0046] The working principle of the water resistance box is described below:

[0047] Combined with Figure 2 , after the water storage tank is installed, there is a certain height gap between its lower end and the lower box body 12. A paddle 80 connected to an external drive source is pivotally connected in this gap to realize the agitation of the liquid in the resistance cavity 40. In the working state, the external drive source (i.e., when pulled by the user) drives the paddle 80 to rotate around its rotation axis. The liquid in the resistance cavity 40 generates a certain resistance to the rotation of the paddle 80 and transmits it to the user's hand. Part of the liquid in the resistance cavity 40 is continuously thrown into the water storage cavity 30 through the water inlet channel 14 under the continuous agitation of the paddle 80. The liquid in the water storage cavity 30 adjusts the height of the lowest position of the overflow port 62 through the rotation of the adjusting member 50, thereby controlling the liquid capacity in the water storage cavity 30. Increasing or decreasing the liquid capacity in the water storage cavity 30 can realize the adjustment process of the resistance of the paddle 80.

[0048] Preferably, as Figure 3 , 4As shown in FIGS. 5, the overflow wall 60 includes a pair of side walls 63 arranged relatively parallel to each other and a U-shaped wall 64 connected between the same sides of the two side walls 63. An overflow port 62 is formed on one side of the two side walls 63 away from the U-shaped wall 64. The center of the U-shaped wall 64 is opposite to the center position of the water storage bucket 20 to form an axially penetrating channel (not marked in the figure, integrated with the overflow channel 61) that penetrates up and down. Thus, by overlapping the positions of the overflow wall 60 and the center of the water storage bucket 20, the axially penetrating channel of the overflow wall 60 can smoothly pass through the corresponding drive shaft for controlling the rotation of the paddle 80, and the liquid can normally enter the resistance chamber 40 along the overflow channel 61 inside the overflow wall 60, thereby combining the water inlet and outlet structure of the water storage bucket 20 with the drive structure of the paddle 80 to achieve a higher degree of integration.

[0049] Furthermore, the tops of the U-shaped wall 64 and the side walls 63 extend to a position flush with the upper edge of the water storage bucket 20. In this embodiment, the gap formed by the water inlet channel 14 is still above the top of the water storage bucket 20, so there is a vertical height difference with the overflow port 62 of the overflow wall 60, preventing the liquid in the water storage bucket 20 from being unable to remain.

[0050] Preferably, as Figure 6 、 7 As shown in FIGS. 8, the adjusting member 50 further includes a connecting shaft 52 and a knob 51 provided at the top of the connecting shaft 52 to control the rotation of the connecting shaft 52. The shielding structure 70 is disposed around the outer peripheral side of the connecting shaft 52. In this embodiment, the connecting shaft 52 extends from the upper end to the inner top wall of the upper box body 11, and the knob 51 passes through the upper box body 11 and is connected to the connecting shaft 52. A corresponding driving part can also be provided on the knob 51. For example, manual driving can be directly achieved by rotating the knob 51, and electric control driving can connect the knob 51 to an external driving motor, etc. to achieve electric control. In addition, in order to further enhance the adjustment effect of the knob 51, a corresponding locking structure can be added to the knob 51 so that the shielding structure 70 can be locked at any position, making the process of its stepless adjustment more stable and controllable.

[0051] Preferably, as Figure 6 、 7 As shown in FIGS. 8, the shielding structure 70 includes a fan-shaped bottom plate 71 and a shielding plate 72 extending upward along the circumferential edge of the bottom plate 71. The top end of the shielding plate 72 is in a spiral shape with a linearly increasing height, so that the shielding plates 72 at different positions enclose overflow edges with different height positions with the overflow port 62. In this embodiment, the outer surface of the shielding plate 72 is in close contact with the edges of the two side walls 63, so that a sealed part and an overflow edge above the sealed part can be enclosed between the shielding plate 72 and the overflow port 62.

[0052] Preferably, as Figure 6 、 7As shown in FIGS. 7 and 8, a horizontal section with a consistent height is provided at the highest position of the baffle 72, so that the baffle 72 corresponding to the horizontal section forms an initial end 74 with the largest overlapping shielding area with the overflow port 62. In this embodiment, the horizontal height of the initial end 74 is slightly lower than the upper edge of the water storage bucket 20. This position is the starting position of the adjustment, corresponding to the highest water storage position in the water storage bucket 20. As the connecting shaft 52 rotates, the overlapping area between the baffle 72 and the overflow port 62 gradually decreases, and the position of the lowest end of the overflow port 62 also becomes lower and lower, corresponding to the gradually decreasing water level in the water storage bucket 20. The liquid in the resistance cavity 40 gradually increases, and the resistance also gradually increases, forming a linear resistance adjustment process that changes with the shielding structure 70.

[0053] In this embodiment, the lowest position of the baffle 72 is slightly higher than the bottom plate 71, forming a terminal end 75 corresponding to the initial end 74. The baffle 72 between the initial end 74 and the terminal end 75 has a linearly varying height.

[0054] Preferably, as shown in FIGS. Figure 6 7 7 and 8, a connecting piece 73 is provided between the baffle 72 and the connecting shaft 52. The highest position of any connecting piece 73 is consistent with the top end of the baffle 72. Through the connecting piece 73, the connection strength between the baffle 72 and the connecting shaft 52 can be further enhanced.

[0055] Preferably, as shown in FIG. Figure 4 9, a rotating bump 22 protrudes from the inner bottom of the water storage bucket 20 and is located on one side of the overflow port 62. A rotating hole (not marked in the figure) matching the rotating bump 22 is provided at the lower end of the rotating shaft. Through the cooperation of the rotating bump 22 and the rotating hole, the connecting shaft 52 of the adjusting member 50 is restricted between the rotating bump 22 and the installation opening reserved for the adjusting member 50 by the upper box body 11, making the rotation process of the adjusting member 50 more stable and controllable.

[0056] Preferably, as shown in FIGS. Figure 7 10 8 and 11, the bottom plate 71 is in a D shape with a central angle of 180°.

[0057] Specifically, as an alternative to the adjusting member, the shielding structure can also be realized by a rack structure, such as an arc rack with a linearly varying edge. Its front surface coincides with the overflow port to intercept the liquid in the water storage cavity, and its back surface forms a tooth groove arranged along its arc surface. The main body of the adjusting member is meshed with the tooth groove on the back surface of the arc rack through a gear arranged on the connecting shaft. Thus, when the knob of the adjusting member rotates, through the meshing transmission of the gear and the tooth groove, the arc rack moves along its arc extension direction. At this time, the edge of the arc rack on the overflow port has a height change due to its linearly varying edge, thereby realizing the adjustment of the overflow along the height. In addition, it can also be realized by other similar structures with linearly varying edges, which are not limited here.

[0058] The utility model overcomes the deficiencies of the traditional water resistance system in terms of resistance adjustment, realizes fast and smooth stepless adjustment, and greatly improves the user experience and exercise effect. Specifically, its main advantages include:

[0059] 1. By rotating the adjusting member 50 to control the height of the overflow port 62, there is no need to manually add or subtract the water volume in the water tank, enabling the user to instantly adjust the resistance during exercise, meet different intensity requirements, and improve the flexibility and efficiency of exercise.

[0060] 2. The special design of the shielding structure 70 causes a linear change in the height of the overflow port 62, realizing continuous and smooth adjustment of the resistance within a certain range, avoiding the discontinuous adjustment phenomenon that may occur in the traditional system, and ensuring the smoothness and comfort of the exercise process.

[0061] In summary, the utility model not only solves the problems of inconvenient adjustment, missing positioning, and stepless adjustment limitations existing in the existing water resistance system, but also improves the convenience, accuracy, and safety of resistance adjustment, providing a more efficient and personalized fitness solution for users.

[0062] The above has made an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
