Description

Technical Field

[0001] The utility model relates to the technical field of water resistance box structures, in particular to a water resistance box structure with wide-range stepless adjustment. 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 the 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 advantage of the water resistance system is that it can instantaneously adjust the resistance according to the user's needs. Through the dynamic change 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 movement cycle can ensure that the muscles get a 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 systems:

[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, restricting the user's ability to flexibly adjust the resistance according to personal status or training goals.

[0006] 2. 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 a water resistance box structure with wide-range stepless adjustment, and this case is thus generated. Content of the Utility Model

[0008] In order to solve the problems of inconvenient rapid adjustment, lack of positioning, and limitations of stepless adjustment, the technical solution of the utility model is as follows:

[0009] A water resistance box structure with wide-range stepless adjustment, comprising:

[0010] A water tank main body, inside which there is a water storage bucket to divide the inner space of the water tank main body into a water storage cavity inside the water storage bucket and a resistance cavity between the water storage bucket and the water tank main body. The side wall of the water storage bucket is provided with a water inlet channel at a high position and a water outlet channel below the height of the water inlet channel;

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

[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, an opening extending from the bottom to the top is formed through the side wall of the water storage bucket to form the water outlet channel.

[0014] Preferably, the adjusting member further includes a connecting shaft and a knob arranged at the top end of the connecting shaft to control the rotation of the connecting shaft, and the shielding structure is arranged around the outer peripheral side of the connecting shaft.

[0015] 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 overflow ports with different height positions are formed between the shielding plates at different positions and the water outlet channel.

[0016] 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 water outlet channel.

[0017] Preferably, a connecting piece is arranged 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.

[0018] Preferably, a first limiting edge in an arc shape and adapted to the outer circumferential edge of the bottom plate is convexly provided on the inner bottom of the water storage bucket and on one side of the water outlet channel, and a second limiting edge for limiting the rotation angle of the shielding structure is provided inside the first limiting edge.

[0019] Preferably, the first limiting edge is in a C shape and its opening faces the water outlet channel, and the second limiting edge is distributed in a V shape on the side of the first limiting edge away from the water outlet channel, and the V-shaped tip faces the arc center of the first limiting edge.

[0020] Preferably, the bottom plate is in a D shape with a central angle of 180°.

[0021] Preferably, a plurality of limiting grooves arranged around the circumferential center are provided on the side of the first limiting edge close to the water outlet channel, and the bottom plate is provided with a limiting bump that can be in limiting cooperation with any one of the limiting grooves.

[0022] 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:

[0023] 1. By rotating the adjusting 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 enhancing 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 the 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] 3. Taking the initial end as the adjustment starting point allows users to quickly locate the initial position of resistance adjustment and set the required resistance range, enhancing the controllability and personalization of exercise.

[0026] 4. The cooperation between the limiting groove and the limiting bump helps users quickly judge the current resistance level without additional observation or testing.

[0027] In summary, the present utility model not only solves the problems of inconvenient adjustment, lack of positioning, and limitations of stepless adjustment existing in the existing water resistance system, but also improves the convenience, accuracy, and safety of resistance adjustment, providing users with a more efficient and personalized fitness solution.

Detailed implementation manners

[0041] 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.

[0042] Please refer to Figures 1 to 9 , which is a wide-range steplessly adjustable water resistance box structure as the best embodiment of the present utility model, including:

[0043] 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 of the water storage bucket 20 is provided with a water inlet channel 14 at a high position and a water outlet channel 22 below the height of the water inlet channel 14;

[0044] Specifically, 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 to the connecting edge 13 through bolts.

[0045] Specifically, there is at least a partial notch along the connection edge 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. The water outlet channel 22 is opened on the side wall of the water storage bucket 20, thereby forming the vertical height relationship between the water inlet channel 14 and the water outlet channel 22.

[0046] The adjusting member 50 is rotatably arranged on one side of the water outlet channel 22 and includes a shielding structure 60 for shielding the water outlet channel 22. An overflow port 23 for the liquid in the water storage cavity 30 to flow out is formed between the top of the shielding structure 60 and the water outlet channel 22.

[0047] Wherein, the shielding structure 60 is configured such that the height of the lowest position of the overflow port 23 changes linearly as its main body rotates.

[0048] The working principle of the water resistance box is described below:

[0049] Combined with Figure 2 、 3 、4, 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 90 connected to an external drive source is pivotally connected in this gap to agitate 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 90 to rotate around its rotation axis. The liquid in the resistance cavity 40 generates a certain resistance to the rotation of the paddle 90 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 90. The liquid in the water storage cavity 30 adjusts the height of the lowest position of the overflow port 23 through the rotation of the adjusting member 50, thereby controlling the liquid volume in the water storage cavity 30. Increasing or decreasing the liquid volume in the water storage cavity 30 can realize the adjustment process of the resistance of the paddle 90.

[0050] Preferably, as Figure 5 shown, an opening extending from the bottom to the top is formed through the side wall of the water storage bucket 20 to form the water outlet channel 22. The bottom of the water storage channel is flush with the bottom surface of the water storage bucket 20, and a pair of parallel side plates 221 are arranged on both sides thereof to facilitate the formation of a closed connection with the shielding structure 60.

[0051] Preferably, as Figure 5 、 6As shown, the adjusting member 50 further includes a connecting shaft 70 and a knob 80 provided at the top end of the connecting shaft 70 to control the rotation of the connecting shaft 70. The shielding structure 60 is disposed around the outer peripheral side of the connecting shaft 70. In this embodiment, the connecting shaft 70 extends from the upper part to the inner top wall of the upper box body 11. The knob 80 passes through the upper box body 11 and is connected to the connecting shaft 70. Moreover, corresponding driving parts can be provided on the knob 80. For example, manual driving can be directly achieved by rotating the knob 80, and for electric control driving, the knob 80 can be externally connected to a driving motor or the like to achieve electric control. In addition, in order to further enhance the adjusting effect of the knob 80, a corresponding locking structure can be added inside the knob 80 so that the shielding structure 60 can be locked at any rotated position, making the stepless adjustment process more stable and controllable.

[0052] Preferably, as Figure 6 、 7 shown, the shielding structure 60 includes a sector-shaped bottom plate 61 and a shielding plate 62 extending upward along the circumferential edge of the bottom plate 61. The top end of the shielding plate 62 is in a spiral shape with a linearly increasing height so that the shielding plates 62 at different positions enclose overflow ports 23 with different height positions with the water outlet channel 22. In this embodiment, the outer surface of the shielding plate 62 is in close contact with the edges of the two side plates 221 so that a sealing part and an overflow port 23 above the sealing part can be enclosed between the shielding plate 62 and the water outlet channel 22.

[0053] Particularly, as Figure 3 、 6 shown, a horizontal section with a consistent height is provided at the highest position of the shielding plate 62 so that the shielding plate 62 corresponding to the horizontal section forms an initial end 64 with the largest overlapping shielding area with the water outlet channel 22. In this embodiment, the horizontal height of the initial end 64 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 70 rotates, the overlapping area between the shielding plate 62 and the water outlet channel 22 gradually decreases, and the position of the lowest end of the overflow port 23 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 60.

[0054] As Figure 7 shown, in this embodiment, the lowest position of the shielding plate 62 is slightly higher than the bottom plate 61, forming a terminal end 65 corresponding to the initial end 64. The shielding plate 62 between the initial end 64 and the terminal end 65 has a linearly changing height.

[0055] Preferably, as Figure 6 、 7As shown, a connecting piece 63 is provided between the baffle 62 and the connecting shaft 70. The highest position of any connecting piece 63 is consistent with the top end of the baffle 62. Through the connecting piece 63, the connection strength between the baffle 62 and the connecting shaft 70 can be further enhanced.

[0056] Preferably, as Figure 8 shown, a first limiting edge 24 which is arc-shaped and adapted to the outer circumferential edge of the bottom plate 61 is convexly provided on the inner bottom of the water storage bucket 20 and on one side of the water outlet channel 22. A second limiting edge 25 for limiting the rotation angle of the shielding structure 60 is provided inside the first limiting edge 24. The first limiting edge 24 is C-shaped and its opening faces the water outlet channel 22. The second limiting edge 25 is V-shaped and is distributed on the side of the first limiting edge 24 away from the water outlet channel 22, and the V-shaped tip thereof faces the arc center of the first limiting edge 24. As Figure 9 shown, the bottom plate 61 is D-shaped with a central angle of 180°. Cooperating with the first limiting edge 24 can realize the stable rotation of the shielding structure 60, and the second limiting edge 25 with a V-shaped design can cooperate with the shape of the bottom plate 61 to limit its rotation angle within a certain range. When the straight edges of the bottom plate 61 contact the two sides of the V shape respectively, the maximum adjustment range is reached. Within this range, the baffle 62 can be arbitrarily adjusted within the angle range between its lowest position and the initial end 64, which helps to realize stepless adjustment.

[0057] In this embodiment, a positioning and installation hole 27 for cooperating with the connecting shaft 70 is provided at the center of the first limiting edge 24.

[0058] Preferably, as Figure 8 shown, a plurality of limiting grooves 26 are provided on the side of the first limiting edge 24 close to the water outlet channel 22 and are arranged around its circumferential center. The bottom plate 61 is provided with a limiting bump (not shown in the figure) that can be in limiting cooperation with any one of the limiting grooves 26. When the user rotates the adjusting member 50, the limiting bump will produce a slight sense of blockage or a "click" sound when passing through each limiting groove 26. This provides clear tactile and auditory feedback for the user to help them quickly judge the current resistance level without additional observation or testing.

[0059] 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:

[0060] 1. By rotating the adjusting member 50 to control the height of the overflow port 23, there is no need to manually add or subtract the water volume in the water tank, so that the user can instantaneously adjust the resistance during the exercise process, meet different intensity requirements, and improve the flexibility and efficiency of the exercise.

[0061] 2. The special design of the shielding structure 60 causes a linear change in the height of the overflow port 23, 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 fluency and comfort of the exercise process.

[0062] 3. Taking the initial end 64 as the adjustment starting point enables users to quickly locate the initial position of resistance adjustment and set the required resistance range, enhancing the controllability and personalization of the exercise.

[0063] 4. The cooperation between the limit groove 26 and the limit bump helps users quickly judge the current resistance level without additional observation or testing.

[0064] In summary, the present utility model not only solves the problems of inconvenient adjustment, lack of positioning, and stepless adjustment limitations existing in the existing water resistance system, but also improves the convenience, accuracy, and safety of resistance adjustment, providing users with a more efficient and personalized fitness solution.

[0065] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present 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 present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
