Description

Adjustment structure of inclined water resistance box and rowing machine Technical Field

[0001] The utility model relates to the technical field of rowing machines, in particular to an adjustment structure of an inclined water resistance box and a rowing machine. Background Art

[0002] Rowing machines, also known as rowing machines, rowing machines, rowing machines, rowing machines, ergometers, land-based rowing machines, and indoor rowing machines, are machines used for training purposes to simulate the sport of rowing on water. Currently, rowing machines offer three main resistance modes: wind resistance, magnetic resistance, and water resistance. Water-resistance rowing machines offer the best simulation technology, allowing users to experience the sight, sound, and feel of real rowing. During exercise, the fluid resistance and the changes in wheel speed are used to strengthen the body's muscles in a short period of time, particularly in the legs, waist, upper limbs, chest, and back. Each complete contraction and extension provides a full aerobic workout for all muscles. Technical issues

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is 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 invention and are not intended to limit the present invention. Example

[0037] Please refer to Figures 1 to 7, which are an adjustment structure of an inclined water resistance box as Example 1 of the present utility model, including: a water tank 10, a water storage barrel 20, and an adjustment block 30, wherein the water tank 10 is arranged at an angle; the water storage barrel 20 is arranged at an angle on the inner side of the water tank 10, and a water inlet channel 201 is provided between the upper part of the water storage barrel 20 and the top of the inner side of the water tank 10, and a water outlet channel 202 is provided on the side of the water storage barrel 20 near the bottom; the adjustment block 30 is provided between the water storage barrel 20 and the inner side of the water tank 10, and is slidably connected to the water storage barrel 20, and the sliding adjustment block 30 is used to adjust the opening of the water outlet channel 202. The upper part in this embodiment is the high position when the water barrel 20 is in a tilted state. When the paddle 60 rotates, it can drive the liquid to move along the outer wall of the water barrel 20. At the high point, part of the liquid can fall into the water barrel 20 through the water inlet channel 201, while the water outlet channel 202 is not located at the lowest position, but close to the side wall at the lowest position. The adjustment structure of the present invention adjusts the opening of the water outlet channel 202 by providing an adjustment block 30, so that the water level in the water barrel 20 is at different heights. When the paddle 60 in the rowing machine rotates, the water in the water tank 10 enters the water barrel 20 through the water inlet channel 201. When the water level reaches the adjusted height, the excess water will be discharged through the water outlet channel 202, thereby adjusting the water resistance.

[0038] Please refer to Figure 4 for details. The adjustment structure also includes a driving member 40 for driving the adjustment block 30 to slide on the water storage barrel 20. The driving member 40 includes a rotating rod 41 and a gear 42 mounted on the rotating rod 41. A plurality of tooth grooves 32 are provided on the inner side of the adjustment block 30 to cooperate with the gear 42. When the driving member 40 rotates, the gear 42 cooperates with the tooth grooves 32 to drive the adjustment block 30 to slide in the water storage barrel 20, thereby adjusting the opening of the water outlet channel 202 to achieve different heights of the liquid in the water storage barrel 20. Specifically, the water storage barrel 20 is used to divide the chamber in the water tank 10 into a water storage space and a resistance space, wherein the water storage space is located inside the water storage barrel 20, and the resistance space is located inside the water tank 10 and outside the water storage barrel 20. During the stirring process of the paddle 60, the liquid in the resistance space enters the water storage space through the water inlet channel 201, and the water level in the water storage space will be determined according to the position of the highest point of the regulating block 30. The excess liquid flows into the resistance space through the water outlet channel 202 to ensure that the required resistance is achieved during exercise.

[0039] Please refer to Figure 2 for details. The adjustment structure also includes a rotating shaft 50 and a paddle 60 arranged at the lower end of the rotating shaft 50. The rotating shaft 50 passes through the top of the water storage barrel 20 and is connected to the paddle 60; the paddle 60 includes a plurality of connecting rods 61 one end of which is connected to the lower end of the rotating shaft 50 and is perpendicular to the central axis of the rotating shaft 50, a connecting ring 62 arranged at the other end of the connecting rod 61, and a plurality of blades 63 arranged on the connecting ring 62. Several connecting rods 61 are located below the water storage barrel 20, and several blades 63 are located outside the water storage barrel 20.

[0040] Referring specifically to Figures 2 and 3 , the water tank 10 comprises a mating lower shell 11 and upper shell 12, with a water storage tank 20 disposed within the upper shell 12. The water storage tank 20 comprises a bottom shell 21 and a side portion 22 disposed on the outer edge of the bottom shell 21. The side portion 22 has a groove formed to form a water inlet channel 201, and a water outlet channel 202 disposed within the side portion 22. The bottom shell 21 of the water storage tank 20 also includes a sleeve 23 that sleeves over the outer surface of the rotating shaft 50 to prevent most liquid from flowing along the sidewall of the rotating shaft 50 into the resistance space. The water storage tank 20 is constructed of plastic, with the bottom shell 21, side portion 22, and sleeve 23 integrally formed using an injection molding process. A first step is disposed within the upper shell 12, mating with the sidewall. The water storage tank 20 is secured to the upper shell 12 by a plurality of bolts. A plurality of internally threaded holes are provided along the circumference of the first step. The bolts pass through the bottom of the water storage tank 20 and are screwed into the internally threaded holes.

[0041] 5-7 , the adjustment block 30 includes an arc-shaped main body 31 , a first sliding groove 33 and a second sliding groove 34 provided above and below the main body 31 , a plurality of tooth grooves 32 provided on the inner side of the main body 31 , a first sliding step 101 cooperating with the first sliding groove 33 is provided on the top inner side of the water tank 10 (the first sliding step 101 is located at the inner top end of the upper shell 12 ), and a second sliding step 203 cooperating with the second sliding groove 34 is provided on the bottom inner side of the water storage barrel 20 (the second sliding step 203 is located on the bottom shell 21 ). The adjustment block 30 is clamped by the arrangement of the upper shell 12 and the water storage barrel 20 so that the adjustment block 30 can be driven to slide by the driving member 40 .

[0042] 2 , the adjustment structure further includes a knob 70. The driver 40 passes through the water tank 10 and is connected to the knob 70 on the outside of the water tank 10. Rotating the knob 70 rotates the driver 40, which in turn drives the adjustment block 30 to slide along a predetermined trajectory. The upper housing 12 also includes a water inlet 121 communicating with the chamber. A sealing plug 90 is provided on the water inlet 121, facilitating liquid injection and sealing the water inlet 121 with the sealing plug 90. The upper housing 12 also includes a mounting hole 122. A sealing block 80 is provided on the outside of the upper housing 12 at the mounting hole 122. The sealing block 80 can be fastened to the upper housing 12 via a number of screws, providing a certain sealing effect and supporting the knob 70 during rotation. The knob 70 can be fastened to the top of the driver 40 via bolts. The bottom housing 21 of the water storage tank 20 includes an annular step 211 that engages with the bottom of the rotating rod 41 to prevent the driver 40 from shifting during rotation. The sealing structure, reinforcing ribs, and locking methods of bolts or screws involved in this embodiment are all conventional settings of those skilled in the art and will not be described in detail.

[0043] The working principle of the adjustment structure of the utility model is as follows:

[0044] Before use, first inject the required liquid through the water injection hole 121, then rotate the knob 70 to drive the adjusting block 30 to rotate, and the liquid in the water storage barrel 20 can enter the resistance space through the water outlet channel 202. During exercise, the paddle 60 rotates, and the liquid in the resistance space flows into the water storage space through the water inlet channel 201, and the liquid flowing into the water storage space flows back to the resistance space through the water outlet channel 202. When it is necessary to increase the resistance, rotate the adjusting block 30 to increase the opening of the water outlet channel 202, lower the liquid height in the water storage barrel 20, and more liquid flows into the resistance space to increase the resistance during exercise. When it is necessary to reduce the resistance, rotate the adjusting block 30 to reduce the opening of the water outlet channel 202. After multiple rotations of the paddle 60, the liquid in the resistance space enters the water storage space through the water inlet channel 201. Since it has not reached a certain height, the liquid will not be discharged from the water outlet channel 202 to the resistance space, and the required resistance can be gradually achieved. Example

[0045] Please refer to Figures 1 to 7, which show a rowing machine as Example 2 of the present utility model, including an adjustment structure. The adjustment structure adopts the adjustment structure of the inclined water resistance box in Example 1.

[0046] To sum up, the adjustment structure of the present invention adjusts the opening of the water outlet channel by setting an adjustment block, so that the water level in the water storage barrel is at different heights. When the blades in the rowing machine rotate, the water in the water tank enters the water storage barrel through the water inlet channel. When the water level reaches the adjusted height, the excess water will be discharged through the water outlet channel, thereby adjusting the water resistance.

[0047] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
