Description

Technical Field

[0001] This utility model belongs to the field of sports equipment technology, specifically relating to an underwater slope treadmill. Background Technology

[0002] Running is one of the most common forms of exercise, improving physical fitness and cardiovascular function. It requires no equipment and has no strict requirements regarding location. Underwater running is also a form of exercise. Because the buoyancy of water reduces the force of gravity on the body, the pressure on the joints is greatly reduced, effectively minimizing the risk of injury to the leg joints. Underwater running is also a very suitable rehabilitative exercise for people with joint or muscle injuries. Many professional athletes use cross-training methods such as underwater running. Furthermore, the resistance of water is much greater than that of air, resulting in a significant increase in calorie expenditure, making it ideal for those seeking weight loss.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0042] Example:

[0043] like Figure 1-6 As shown, this embodiment provides an underwater slope treadmill, including a treadmill housing 1, and the treadmill housing 1 is provided with a running platform device 2, a slope adjustment device 3, a buffer support device 4 and a water inlet and outlet device 5.

[0044] The treadmill housing 1 has a training chamber 101 for users to run and train. The running platform device 2, the incline adjustment device 3, and the buffer support device 4 are located inside the training chamber 101. The water inlet and drainage device 5 are connected to the training chamber 101.

[0045] One end of the treadmill device 2 is rotatably engaged with the treadmill housing 1;

[0046] The buffer support device 4 has a buffer support end, and the adjustment end of the slope adjustment device 3 is provided with a guide seat 306. The guide seat 306 is provided with a guide part 308 and a fixing part 309. During the rotation of the running platform device 2 relative to the treadmill box 1, the running platform device 2 can contact the adjustment end of the slope adjustment device 3, and the buffer support end can enter the fixing part 309 through the guide part 308, and the buffer support end is in a compressed state.

[0047] The underwater treadmill of this embodiment firstly has an inlet and outlet drainage device 5, which allows users to achieve the effect of simulating running in water within the training chamber 101. Secondly, it is equipped with an incline adjustment device 3 and a buffer support device 4. When the user trains using the running platform device 2, the adjustment end of the incline adjustment device 3 contacts the running platform device 2, which can adjust the rotation angle of the running platform device 2 relative to the treadmill housing 1. At the same time, when the running platform device 2 rotates towards the bottom of the treadmill housing 1, the buffer support device 4, through contact with the guide seat 306, can provide elastic support and buffer for the running platform device 2, thereby distributing the support force of the incline adjustment device 3 and improving the overall service life. Moreover, when the incline adjustment device 3 releases its adjustment force, the elastic force of the buffer support end automatically lifts the running platform device 2 and restores its position, improving the user experience.

[0048] The specific structure of the slope adjustment device 3 in this embodiment is as follows:

[0049] It includes an electric push rod device 301, a first adjusting arm 302, a second adjusting arm 303, and a first rotating shaft 304. The first adjusting arm 302, the second adjusting arm 303, and the first rotating shaft 304 form the adjusting end of the slope adjusting device 3.

[0050] The first rotating shaft 304 is rotatably engaged with the treadmill housing 1. One end of the first adjusting rotating arm 302 is hinged to the push rod end of the electric push rod device 301. The other end of the first adjusting rotating arm 302 is connected to the first rotating shaft 304. One end of the second adjusting rotating arm 303 is connected to the first rotating shaft 304. The other end of the second adjusting rotating arm 303 is provided with a roller 305. The guide seat 306 is connected to the second adjusting rotating arm 303.

[0051] Meanwhile, the specific structural configuration of the slope adjustment device 3 and the training chamber 101 is as follows:

[0052] A running water tank 102 is provided inside the training cabin 101. The water inlet and water outlet of the water inlet and outlet device 5 are connected to the running water tank 102. The running platform device 2 is located inside the running water tank 102 and one end of the running platform device 2 is rotatably engaged with the running water tank 102.

[0053] The running water tank 102 in this embodiment is used to store water. The water in the running water tank 102 is discharged and supplied through the water inlet and outlet device 5. The electric push rod device 301 and the first adjusting arm 302 are located outside the running water tank 102. The above structure can prevent the electric push rod device 301 from being affected by water, thus achieving a waterproof effect and improving the service life of the electric push rod device 301. Furthermore, the second adjusting arm 303 and the buffer support end of the buffer support device 4 are set inside the running water tank 102. The first rotating shaft 304 rotates and engages with the running water tank 102. More specifically, the running water tank 102 is provided with a rotating seat 310. The first rotating shaft 304 passes through the rotating seat 310 and rotates and engages with the rotating seat 310.

[0054] There are two second adjusting arms 303. A guide seat 306 is located between the two second adjusting arms 303. A guide plate 307 is provided on the guide seat 306 and near the second adjusting arms 303. A guide part 308 and a fixing part 309 are provided on the guide plate 307. The guide part 308 has an arc surface structure and the fixing part 309 has a groove structure.

[0055] In this embodiment, the position of the buffer support device 4 corresponds to the position of the guide plate 307;

[0056] The specific structure of the buffer support device 4 is as follows:

[0057] The device includes a buffer mounting base 401, a buffer spring 402, a buffer connecting base 403, a buffer connecting rod 404, and a buffer rotating cylinder 405. The bottom of the buffer spring 402 is located on the buffer mounting base 401, and the top of the buffer spring 402 is connected to the buffer connecting base 403. There are two buffer springs 402. The buffer connecting rod 404 is connected to the two buffer connecting bases 403. The buffer rotating cylinder 405 is sleeved on the buffer connecting rod 404. The buffer spring 402, buffer connecting base 403, buffer connecting rod 404, and buffer rotating cylinder 405 form the buffer support end of the buffer support device 4. The buffer rotating cylinder 405 can enter the fixing part 309 through the guide part 308.

[0058] During the process of the buffer rotating cylinder 405 entering the fixing part 309 through the guide part 308, the buffer spring 402 is in a compressed state. At the same time, both ends of the buffer rotating cylinder 405 are connected to the buffer spring 402 through the buffer connecting rod 404 and the buffer connecting seat 403. That is, the buffer support device 4 corresponding to the position of the guide plate 307 has two buffer springs 402, which reduces the risk of shaking when using a single buffer spring 402 and ensures the stability of the support force for the slope adjustment device 3.

[0059] The running water tank 102 in this embodiment includes a top tank 1021, an inclined tank 1022, and a bottom tank 1023. The inclined tank 1022 is located between the top tank 1021 and the bottom tank 1023. The top tank 1021 is provided with a water inlet connected to the water inlet end of the water inlet and drainage device 5. The bottom tank 1023 is provided with a drain outlet connected to the drain end of the water inlet and drainage device 5. The inclined tank 1022 is provided with a telescopic device 107. The telescopic end of the telescopic device 107 is connected to the running platform device 2.

[0060] The aforementioned running water tank 102 has a sloping tank section 1022, and the overall shape of the tank is inclined. The above design is based on the fact that when the user simulates running in water in the training chamber 101, the user's legs are located in the area of ​​the sloping tank section 1022 and the bottom tank section 1023, and further close to the area of ​​the bottom tank section 1023. Therefore, the tank is inclined, which increases the water storage capacity of the bottom tank section 1023 to meet the water storage needs of training. There is no need to store too much water in the top tank section 1021. Compared with the traditional square tank structure, it can reduce the water storage capacity and is more environmentally friendly and energy-saving.

[0061] In this embodiment, under the default state, i.e., when the treadmill device 2 is horizontal and the push rod of the electric push rod device 301 is fully retracted, the roller 305 is in contact with the bottom of the treadmill device 2. (See also...) Figure 3 and Figure 6 ;

[0062] You can refer to Figure 4 and Figure 5 It needs to be explained that: Figure 4 The structure of the running water tank is hidden in the middle. Figure 5 The structure of the guide seat is hidden. When the push rod of the electric push rod device 301 is extended and fully extended, the roller 305 contacts the bottom of the running platform device 2. At this time, the push rod of the electric push rod device 301 causes the first adjusting arm 302 to rotate. The rotation of the first adjusting arm 302 drives the first rotating shaft 304 to realize the rotation of the second adjusting arm 303. At the same time, the running platform device 2 rotates relative to the area of ​​the bottom groove 1023 under its own weight or the user's weight. The bottom of the running platform device 2 contacts the roller 305 on the second adjusting arm 303 to ensure the stability of the rotation of the running platform device 2. During the above process, the guide plate 307 moves closer to the buffer support device 4, and the buffer rotating cylinder 405 can enter the fixing part 309 through the guide part 308. At this time, the running platform device 2 is parallel to the inclined groove 1022, and the running platform device 2 is at the maximum tilt angle.

[0063] Meanwhile, in the above structure, a telescopic device 107 is provided. The telescopic end of the telescopic device is connected to the running platform device 2. The user can rotate the running platform device 2 in a direction away from the bottom groove 1023 so that the opening of the running water tank 102 is in an open state, which is convenient for cleaning the inside of the running water tank 102. The telescopic device ensures the stability of the running platform device 2 in the direction away from the bottom groove 1023 during rotation.

[0064] In this embodiment, the treadmill housing 1 has an opening that communicates with the training chamber 101. A door 103 is provided at the opening. One side of the door 103 is rotatably mounted on one side of the opening, and a locking device 104 is provided on the other side of the door 103. The door 103 is connected to the other side of the opening through the locking device 104. The door 103 allows the user to easily enter the training chamber 101.

[0065] Meanwhile, a handrail device is provided inside the treadmill housing 1, i.e. the training chamber 101. The handrail device includes a side handrail 105 and a front handrail 106. The side handrails are located on both sides of the front handrail, making it convenient for users to hold on during training and improving the safety of exercise.

[0066] The treadmill device 2 in this embodiment includes a treadmill base 201, a front roller 202, a rear roller 203, a running belt 204, and a rotating motor 205. The front roller 202 and the rear roller 203 are rotatably engaged with the treadmill base 201. The running belt 204 is sleeved on the front roller 202 and the rear roller 203. The drive end of the rotating motor 205 is connected to the front roller 202. The rotating motor 205 drives the front roller 202 to rotate, thereby driving the running belt 204 to circulate back and forth between the front and rear rollers 203 and 202.

[0067] The water inlet and outlet device 5 includes a water supply device 501, a water supply pipe 502 and an outlet pipe 503.
