[0002] Walking machines are common fitness equipment in homes and gyms. The use of walking machines allows trainees to take a walk after meals, do hill climbing training, etc. at home without going out, so as to achieve the purpose of strengthening their bodies. During the use of the walking machine, the slope of the walking machine treadmill needs to be adjusted according to the needs of each person. Therefore, some walking machines with adjustable slope have appeared on the market.

[0003] For example, the Chinese utility model patent, "A Walking Machine with Rear-Mounted Handrails," with patent publication number CN216725654U, involves mounting a caster bracket with casters on the rear side of a treadmill. The caster bracket is secured to the treadmill via a first fixing bolt and a second fixing bolt. The caster bracket is provided with a plurality of fixing holes at different heights that engage with the second fixing bolts. The second fixing bolts, engaging with the fixing holes at different heights, adjust the height of the rear side of the treadmill relative to the ground.

[0004] The above solution adjusts the height of the caster bracket at the rear of the treadmill relative to the ground, thereby adjusting the slope of the entire treadmill. The rear side of the treadmill is supported by the rear wheels and caster brackets, and the structure is unstable and prone to sliding. Utility Model Content

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0027] This embodiment mainly describes a walking machine with adjustable slope, as follows:

[0028] like Figures 1 to 6As shown, a walking machine with adjustable slope includes a treadmill frame 1 and a slope adjustment mechanism. The slope adjustment mechanism is used to adjust the slope of the walking machine. The slope adjustment mechanism includes a support block 2 and a base 3. The support block 2 is fixedly connected to the front bottom of the treadmill frame 1. The fixed connection method can be fixed to the treadmill frame 1 by welding, or by other connection methods, such as bolts and nut assemblies. The base 3 is rotatably connected to the support block 2 and can be locked and fixed by a fixing member 34. When the base 3 rotates around the support block 2 to be in a folded state, at least one of the side surface of the base 3 or the bottom of the support block 2 contacts the ground to form support. At this time, walking training can be performed; when the base 3 rotates around the support block 2 to be in an unfolded state, the base 3 is locked by the fixing member 34, and the front end of the treadmill frame 1 is lifted by the base 3. At this time, the ground and the treadmill frame form an inclined angle, and the bottom of the base 3 forms support with the ground. At this time, climbing training can be performed. Compared with walking training, climbing training can consume more calories in the same amount of time and increase training intensity. Whether the base 3 is in the unfolded or folded state, the contact area with the ground is large, the structure is stable, and the stability of the walking machine is increased, and it is not easy to slip. The support height of the base 3 is different when the base 3 is in the unfolded and folded states, and the support height of the base 3 when the base 3 is unfolded is greater than the support height when the base 3 is folded.

[0029] like Figure 4 and Figure 5 As shown, the base 3 has a U-shaped mounting groove 31, the shape of the U-shaped mounting groove 31 is adapted to the support block 2, and a first mounting hole 311 is provided on both side walls of the U-shaped groove, and the support block 2 is provided with a second mounting hole 22 adapted to the first mounting hole 311. The support block 2 is inserted into the U-shaped mounting groove 31 and the support block 2 is rotatably connected to the U-shaped mounting groove 31 by passing the rotating shaft 32 through the first mounting hole 311 and the second mounting hole 22, so that the mounting seat can rotate around the rotating shaft 32. The outer end of the rotating shaft 32 has a thread, and the end of the rotating shaft 32 is limited by a nut to prevent the rotating shaft 32 from slipping.

[0030] Preferably, the bottom of the U-shaped mounting groove 31 has a first arc surface 33, the center of each arc on the first arc surface 33 is collinear with the rotation center of the base 3 around the support block 2, and the diameter of each arc on the first arc surface 33 is greater than or equal to the maximum distance L from the rotation center to the bottom edge of the support block 2. Figure 6 As shown, the first arc surface 33 is provided to prevent the base 3 from interfering with the U-shaped mounting groove 31 and being unable to rotate when the base 3 rotates around the rotation axis 32 .

[0031] like Figure 4 、 Figure 5 and Figure 6As shown, the support block 2 is provided with a first fixing hole 21, and the base 3 is provided with a second fixing hole 35 adapted to the first fixing hole 21. The fixing member 34 is inserted into the first fixing hole 21 and the second fixing hole 35 to fix the support block 2 and the base 3. The number of the first fixing hole 21 is at least one, preferably two. The number of the first fixing hole 21 is one. When the base 3 is unfolded, the second fixing hole 35 coincides with the first fixing hole 21; the number of the first fixing holes 21 is two. When the base 3 is folded, the second fixing hole 35 coincides with one of the first fixing holes 21. When the base is unfolded, the second fixing hole 35 coincides with the other first fixing hole 21. When the second fixing hole 35 coincides with the first fixing hole 21, the fixing member 34 is passed through the first fixing hole 21 and the second fixing hole 35 to fix the base 3 to the support block 2 and prevent the fixed base from rotating. The fixing member 34 can be a steel ball pin or a bolt and nut assembly.

[0032] The base 3 includes an upper top surface 36, a lower bottom surface 37, a left side surface 38, and a right side surface 39. A second arc surface 310 is located between the upper top surface 36 and the right side surface 39 to prevent interference with the treadmill base 3 during rotation. The centers of the arcs on the second arc surface 310 are collinear with the rotation center of the base 3 around the support block 2. When the base 3 is folded, the left side surface 38 abuts the ground, while when the base 3 is unfolded, the lower bottom surface 37 abuts the ground. A second arc surface may also be located between the left side surface 38 and the upper top surface 36. In this case, the base 3 can rotate 180 degrees about the rotation axis 32, allowing the base 3 to fold left or right. Preferably, the junction between the left side surface 38 and the upper top surface 36 forms a limiting angle 4, which restricts further rotation of the base 3 when the base 3 is fully unfolded.

[0033] Preferably, there are two slope adjustment mechanisms, which are symmetrically arranged on both sides of the treadmill frame 1 to improve the stability of the treadmill frame.

[0034] When the treadmill is in the folded state, the treadmill is parallel to the ground, and walking training can be performed. When climbing training is required, the bases 3 on both sides of the treadmill frame 1 are rotated around the rotation axis 32 so that the second fixing holes 35 correspond to the first fixing holes 21, and the steel ball pins are inserted into the second fixing holes 35 and the first fixing holes 21 to fix the base 3 and the support block 2. At this time, the treadmill frame forms an angle with the ground, and climbing training can be performed. This solution has a simple structure and is easy to adjust.
