[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships based on the positions or location relationships during normal use of the product.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. The drawings of the embodiments of the present invention are provided with a coordinate system XYZ, wherein the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0030] The utility model provides a slope adjustment mechanism, combined with Figure 1-10 As shown, it includes a body 1, and the front bottom of the body 1 is rotatably connected to a rotating member 3, and a first limit block 21 and a second limit block 22 are protruded from the body 1, and the first limit block 21 and the second limit block 22 are respectively located at the beginning and end of the rotation path of the rotating member 3, and a third limit block 31 is provided on the side of the rotating member 3 close to the first limit block 21, and a first limit opening 32 is provided on the side of the rotating member 3 close to the second limit block 22. When the first limit block 21 abuts against the third limit block 31, the body 1 is at the minimum slope; when the rotating member 3 is rotated until the first limit opening 32 abuts against the second limit block 22, the slope of the body 1 increases.

[0031] like Figure 1-3As mentioned above, in this embodiment, the slope adjustment mechanism is provided at both ends of the machine body 1, and is located near the front end of the machine body 1. When the first stopper 21 abuts the third stopper 31, the rotating member 3 is in a retracted state, and the slope of the machine body 1 remains unchanged. When the second stopper 22 abuts the first stopper 32, the rotating member 3 is in an extended state, and the front of the machine body 1 is raised, increasing the slope.

[0032] The slope adjustment mechanism in the present invention limits the rotation position of the rotating member 3 by setting the first limit block 21 and the third limit block 31 to cooperate with each other, and the second limit block 22 and the first limit opening 32 to cooperate with each other, so that the user can increase the slope of the body 1 by rotating the rotating member 3, simulate climbing and other types of exercise, enhance the intensity of exercise, and adapt to the different usage needs of users.

[0033] It also includes bolts, and the body 1 is fixedly connected to the fixing member 2 through the bolts. The first limit block 21 and the second limit block 22 are arranged at both ends of the fixing member 2, and one end of the rotating member 3 is rotatably connected to the fixing member 2.

[0034] like Figure 6 and 7 In this embodiment, the fixing member 2 is approximately rectangular, and the rotating member 3 is rotatably connected to the middle position of the fixing member 2. A through hole is provided in the middle position of the fixing member 2 to facilitate fixing to the body 1 by bolts, thereby facilitating disassembly and transportation.

[0035] Both the first limit block 21 and the second limit block 22 are parallel to the horizontal plane. The first limit block 21 is located on the right side of the upper end of the fixing member 2, and the second limit block 22 is located on the left side of the lower end of the fixing member 2. The second limit block 22 is approximately rectangular, and the first limit opening 32 is adapted to fit the second limit block 22, forming a 90-degree angle with the first limit opening 32. When the second limit block 22 is engaged with the first limit opening 32, the first limit opening 32 not only provides a limiting function, but also cooperates with the support portion 33 to bear weight, thereby stabilizing the structure.

[0036] A supporting foot 11 is provided at the bottom of the rear end of the machine body 1 , and a supporting portion 33 is provided on the rotating member 3 . The supporting portion 33 and the supporting foot 11 support the front and rear ends of the machine body 1 respectively.

[0037] like Figure 1 As described above, in this embodiment, the support leg 11 is arc-shaped, and the height of the support portion 33 and the support leg 11 are adapted so that when the rotating member 3 is in the stored state, the upper surface of the body 1 is parallel to the horizontal plane, or the support portion 33 is slightly higher than the support leg 11, so that the body 1 has a certain initial slope.

[0038] The support legs 11 are made of a non-slip material such as rubber to increase friction and prevent the body 1 from moving. The support legs 11 and the support portion 33 cooperate to support the body 1, preventing the motor bottom cover at the bottom of the body 1 from directly contacting the ground, which could cause poor heat dissipation or wear when the body 1 is moved.

[0039] like Figure 3 and 4 As described, the support portion 33 is tilted relative to the third limit block 31. When the first limit opening 32 abuts against the second limit block 22, the rotating member 3 is in the expanded state. At this time, the angle between the support portion 33 and the horizontal plane is less than 90 degrees. In this embodiment, the angle is 60 degrees to make the structure more stable. When the user runs on the body 1, the rotating member 3 is not easy to move.

[0040] A roller 12 is provided at the bottom of the front end of the body 1 , and the height of the roller 12 in the vertical direction is lower than the height of the support foot 11 . When the support foot 11 is lifted, the roller 12 contacts the ground to facilitate moving the body 1 .

[0041] like Figure 2 and 3 As described above, when the user uses the treadmill normally, the roller 12 does not contact the ground. When the user needs to move the body 1, the roller 12 comes into play. The user needs to lift the body 1 from the rear end of the body 1 so that the roller 12 at the front end of the body 1 touches the ground. The user can push or pull the body 1 through the roller 12 to move the overall position of the treadmill.

[0042] When the first limiting opening 32 abuts against the second limiting block 22 , the angle between the supporting portion 33 and the horizontal plane is in the range of 50-70 degrees.

[0043] like Figure 4 As mentioned above, in this embodiment, the angle between the support portion 33 and the horizontal plane is 60 degrees. This arrangement does not affect the elevation of the body 1 while being more conducive to supporting the body 1 and stabilizing the structure.

[0044] A sleeve 34 is provided at one end of the rotating member 3, and an eccentric sleeve 35 is sleeved on the sleeve 34. The sleeve 35 abuts against the ground to support the front of the body 1. When the first limit opening 32 abuts against the second limit block 22, the sleeve 35 can be used to fine-tune the slope of the body 1.

[0045] like Figure 8-10As mentioned above, in this embodiment, the sleeve 35 is made of plastic and has a certain cushioning effect. The eccentrically positioned sleeve 35 allows the user to fine-tune the slope of the housing 1 by utilizing the different distances between the outer surface of the sleeve 35 and the axis of the sleeve 34. After rotating the rotating member 3 until the first stop 32 abuts the second stop block 22, the user can then fine-tune the slope of the housing 1 by rotating the sleeve 35 alone.

[0046] The cross section of the sleeve 35 in the vertical direction is a regular polygon. Figure 10 As described above, when the rotating member 3 is in the expanded state, the polygonal outer edge of the sleeve 35 forms a guide surface, which contacts the ground, so that the supporting structure is more stable and the body 1 is not easy to move when the user is running.

[0047] The number of sides of the regular polygon is 9-11. Figure 10 As mentioned above, in this embodiment, the number of sides of the regular polygon is 10. This arrangement makes the outer surface of the sleeve 35 closer to a circle and the rotation is smoother without affecting the stability of the support. When the user adjusts the slope of the body 1, it is necessary to first lift the body 1 and then rotate the rotating part 3 to the unfolded state. If the user does not rotate the rotating part 3 enough, the sleeve 35 can provide assistance for the rotation of the rotating part 3. When the user releases the body 1, the body 1 presses the rotating part 3 downward under the action of gravity, and the sleeve 35 rotates forward a short distance to make the first limit opening 32 abut against the second limit block 22, thereby stabilizing the structure and preventing the rotating part 3 from breaking.

[0048] The rotation range of the rotating member 3 is 0-90 degrees. Figure 4 and 6 As described above, in this embodiment, when the rotating member 3 rotates 90 degrees from the stowed state to the deployed state, the slope of the body 1 is raised by 3 degrees. Of course, the degree of the raised slope of the body 1 is affected by the length of the rotating member 3. If the rotating member 3 is long, the slope of the body 1 increases more in the deployed state.

[0049] Another embodiment of the present invention provides a treadmill, comprising the slope adjustment mechanism described above.

[0050] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present utility model.
