Description

Technical Field

[0001] This invention relates to the field of exercise equipment, specifically to a non-powered walking machine. Background Technology

[0002] A non-powered treadmill is an indoor exercise device that usually has an adjustable incline. However, the current adjustment method involves the user squatting down and manually rotating the adjustment bracket, which has limited adjustment levels and is relatively cumbersome. Summary of the Invention

[0003] To address the above-mentioned problems, this invention proposes a non-powered walking machine.

[0004] The technical solution adopted in this invention is as follows:

[0005] A non-powered walking machine includes a base, a vertical frame installed at the front end of the base, a walking belt mechanism, a braking mechanism, and an incline adjustment mechanism disposed on the base.

[0006] The slope adjustment mechanism includes two sets of support adjustment components and a control component for controlling the two sets of support adjustment components:

[0007] The control component includes a second rotating member mounted on a vertical frame and a bidirectional ratchet structure, the bidirectional ratchet structure being capable of switching the unidirectional rotation direction of the second rotating member:

[0008] Two sets of support adjustment components are respectively located on the left and right sides of the front end of the base. Each set of support adjustment components includes:

[0009] A support adjustment frame is rotatably mounted on the base in the middle. One end of the support adjustment frame is a tension end, and the other end is a support end, which is used to contact the ground; and

[0010] The second metal wire has one end connected to the tension end and the other end wound around the rotating component;

[0011] When the second rotating component of the control assembly rotates, it can drive the two second metal wires to wind or release synchronously.

[0012] The upper end of the vertical frame has a crossbeam, and the base is equipped with a front axle and a rear axle arranged in parallel.

[0013] In one embodiment of the present invention, the bidirectional ratchet structure includes:

[0014] The gear is fixed to the second rotating component;

[0015] Two ratchet teeth are rotatably mounted on the vertical frame. The two ratchet teeth are the first ratchet tooth and the second ratchet tooth. When the first ratchet tooth engages with the gear, the second rotating component can rotate around the first direction but cannot rotate around the second direction. When the second ratchet tooth engages with the gear, the second rotating component can rotate around the second direction but cannot rotate around the first direction. The first direction and the second direction are opposite.

[0016] Two elastic reset elements, each engaging with a ratchet tooth, are used to give the corresponding ratchet teeth a tendency to rotate toward the gear side;

[0017] A control element is rotatably mounted on a vertical frame, located between two ratchet teeth. The control element has a drive portion that engages with the ratchet teeth, and the control element is used to selectively engage one of the two ratchet teeth with the gear.

[0018] This application utilizes the rotation of the second rotating component to drive the second metal wire to synchronously wind or release. During synchronous winding, the second metal wire pulls the tension end of the support adjustment frame, causing the support end to rotate downwards and the front end of the base to move upwards, increasing the slope. During synchronous release, the support adjustment frame rotates under gravity, causing the support end to move upwards and the front end of the base to move downwards, decreasing the slope. The control component, through a bidirectional ratchet structure, can switch the unidirectional rotation direction of the second rotating component, i.e., it can control whether the slope is adjusted upwards or downwards, and can fix the position after adjustment. This application, through its ratchet structure, allows for more adjustable levels, and the control component is mounted on a vertical frame, making operation convenient and eliminating the need for a person to squat down for adjustment.

[0019] In one embodiment of the present invention, a support wheel is installed on the support end;

[0020] The support adjustment assembly also includes a guide wheel assembly fixed on the base, and the second metal wire passes around the guide wheel assembly;

[0021] The guide wheel assembly includes a lower guide wheel and an upper guide wheel located above the lower guide wheel, with the upper guide wheel positioned above the tension end.

[0022] In one embodiment of the present invention, the control component further includes a second control knob that is circumferentially fixed to the second rotating member;

[0023] The second control knob has a mating hole;

[0024] The control component also includes an assist rod with an end capable of being inserted into the mating hole.

[0025] In one embodiment of the present invention, the walking belt mechanism includes:

[0026] Two first pulleys are installed on the left side of the front axle and the left side of the rear axle, respectively, and the two first pulleys are arranged opposite each other;

[0027] The first belt is wound around the two first pulleys;

[0028] The first support frame is fixed on the base. Multiple rollers are installed on the first support frame at intervals. The rollers on the first support frame roll in contact with the lower surface of the upper part of the first belt.

[0029] Two second pulleys are installed on the right side of the front axle and the right side of the rear axle, respectively, and the two second pulleys are arranged opposite each other;

[0030] The second belt is wound around the two second pulleys;

[0031] The second support frame is fixed on the base. Multiple rollers are installed on the second support frame at intervals. The rollers on the second support frame roll in contact with the lower surface of the upper part of the second belt.

[0032] Two intermediate pulleys are installed in the middle of the front axle and the middle of the rear axle, respectively, and the two intermediate pulleys are arranged opposite each other;

[0033] The intermediate belt is wound around the two intermediate pulleys;

[0034] An intermediate support frame is fixed on the base, and multiple spaced rollers are installed on the intermediate support frame. The rollers on the intermediate support frame roll in contact with the lower surface of the upper part of the intermediate belt.

[0035] Multiple foot pedals, with both ends of each foot pedal fixed to a first belt and a second belt, respectively, forming a ring-shaped foot pedal belt structure;

[0036] The foot pedal includes a plastic body and a metal component embedded in the plastic body.

[0037] In one embodiment of the present invention, both ends of the foot pedal strip have folded edges, one of which is in contact or clearance fit with the side wall of the first belt away from the second belt, and the other folded edge is in contact or clearance fit with the side wall of the second belt away from the first belt.

[0038] In one embodiment of the present invention, the first pulley, the second pulley and the intermediate pulley each have an annular mounting groove, and the sidewall of the annular mounting groove is used to contact and cooperate with the sidewall of the corresponding belt.

[0039] The depth of the annular mounting groove is less than or equal to the thickness of the corresponding belt; or, the depth of the annular mounting groove is greater than the thickness of the corresponding belt. In this case, the side of the foot pedal facing the first belt has an avoidance notch, and the side wall of the annular mounting groove is embedded in the corresponding avoidance notch.

[0041] A brake wheel, fixed to the front axle, is made of metal.

[0042] A movable block is movably mounted on the base, and multiple strong magnets are fixed to the end of the movable block facing the brake wheel.

[0044] The first rotating component is rotatably mounted on the vertical frame;

[0045] A positioning element is mounted on the vertical frame and cooperates with the first rotating component to position the first rotating component at a set angle.

[0046] The first metal wire has one end wrapped around the first rotating component and the other end connected to the moving block. The first rotating component can pull the first metal wire, thereby moving the moving block.

[0047] In one embodiment of the present invention, the braking mechanism includes:

[0048] A brake wheel, fixed to the front axle, is made of metal.

[0049] A movable block is movably mounted on the base, and multiple strong magnets are fixed to the end of the movable block facing the brake wheel.

[0050] An elastic element, disposed between the base and the movable block, is used to give the movable block a tendency to move toward the brake wheel side;

[0053] The first metal wire has one end wrapped around the first rotating component and the other end connected to the moving block. The first rotating component can pull the first metal wire, thereby moving the moving block.

[0054] Both the first rotating component and the positioning element are mounted on the crossbeam;

[0055] There are two brake wheels, which are respectively set on the left and right sides of the front axle. The first pulley and the second pulley on the front axle are used as two brake wheels. There are also two moving blocks and two first metal wires. The two moving blocks are respectively matched with the two brake wheels. One end of each of the two first metal wires is wound around the first rotating component. When the first rotating component is rotated, it can drive the two first metal wires to wind or release synchronously.

[0057] The beneficial effects of this invention are as follows: The rotation of the second rotating component enables the second metal wire to be wound or released synchronously. During synchronous winding, the second metal wire pulls the tension end of the support adjustment frame, causing the support end to rotate downwards and the front end of the base to move upwards, increasing the slope. During synchronous release, the support adjustment frame rotates under gravity, causing the support end to move upwards and the front end of the base to move downwards, decreasing the slope. The control component, through a bidirectional ratchet structure, can switch the unidirectional rotation direction of the second rotating component, i.e., it can control whether the slope is adjusted upwards or downwards, and can be positioned after adjustment. This application, through the ratchet structure, can achieve more adjustment levels, and the control component is mounted on a vertical frame, making operation convenient and eliminating the need for a person to squat down for adjustment.

[0086] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0087] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0088] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0089] The present invention will now be described in detail with reference to the accompanying drawings.

[0090] like Figures 1 to 26 As shown, this embodiment discloses a non-powered walking machine, including a base 1, a vertical frame 2 installed at the front end of the base 1, a walking belt mechanism 3 set on the base 1, a braking mechanism 4, and a slope adjustment mechanism.

[0091] like Figure 3 and 4 As shown, a front axle 11 and a rear axle 12 are mounted on the base 1 in parallel configuration. Figure 2 , 3 As shown in Figure 4, the walking belt mechanism 3 includes:

[0092] Two first pulleys 311 are respectively installed on the left side of the front axle 11 and the left side of the rear axle 12, and the two first pulleys 311 are arranged correspondingly.

[0093] The first belt 312 is wound around the two first pulleys 311;

[0094] The first support frame 313 is fixed on the base 1. Multiple rollers 301 are installed on the first support frame 313 at intervals. The rollers 301 on the first support frame 313 roll in cooperation with the lower surface of the upper part of the first belt 312.

[0095] Two second pulleys 321 are respectively installed on the right side of the front axle 11 and the right side of the rear axle 12, and the two second pulleys 321 are arranged correspondingly.

[0096] The second belt 322 is wound around the two second pulleys 321;

[0097] The second support frame 323 is fixed on the base 1. Multiple rollers 301 are installed on the second support frame 323 at intervals. The rollers 301 on the second support frame 323 roll in cooperation with the lower surface of the upper part of the second belt 322.

[0098] Two intermediate pulleys 331 are respectively installed in the middle of the front axle 11 and the middle of the rear axle 12, and the two intermediate pulleys 331 are arranged correspondingly.

[0099] The intermediate belt 332 is wound around the two intermediate pulleys 331;

[0100] The intermediate support frame 333 is fixed on the base 1. Multiple rollers 301 are installed on the intermediate support frame 333 at intervals. The rollers 301 on the intermediate support frame 333 roll in contact with the lower surface of the upper part of the intermediate belt 332.

[0101] Multiple foot pedal strips 35 are fixed at both ends to the first belt 312 and the second belt 322 respectively, and each foot pedal forms a ring-shaped foot pedal belt structure 34.

[0102] In practical application, the foot pedal 35 includes a plastic body 351. The foot pedal 35 of the walking belt mechanism 3 forming the foot belt structure 34 in this application does not use a pure metal structure, effectively reducing weight. Since the foot pedal 35 is more prone to deformation than a pure metal structure, this application additionally provides a second support frame 323 with rollers 301 to better support the foot pedal 35 and prevent excessive deformation in the middle of the foot pedal 35. The rollers 301 of the intermediate support frame 333 directly contact the foot pedal 35, which can generate significant noise. This application uses a separately provided intermediate belt 332 for cushioning, effectively reducing noise.

[0103] In this embodiment, the foot pedal 35 also includes a metal component 352 embedded in the plastic body 351. By using a plastic body 351 with an embedded metal component 352, the foot pedal 35 effectively reduces weight while maintaining a certain structural strength. In practical applications, the metal component 352 can be made of aluminum or aluminum alloy.

[0104] like Figure 2 and 5 As shown, in this embodiment, both ends of the foot pedal 35 have folded edges 3511. One folded edge 3511 is in contact with or has a clearance fit with the side wall of the first belt 312 away from the second belt 322, and the other folded edge 3511 is in contact with or has a clearance fit with the side wall of the second belt 322 away from the first belt 312.

[0105] The 3511 folded edge enables positioning and limiting, facilitating assembly and ensuring the reliability of the entire structure after installation, preventing deformation and misalignment.

[0106] like Figure 3 and 4 As shown, in this embodiment, the first pulley 311, the second pulley 321 and the intermediate pulley 331 all have annular mounting grooves 302, and the sidewalls of the annular mounting grooves 302 are used to contact and cooperate with the sidewalls of the corresponding belts.

[0107] In this embodiment, the depth of the annular mounting groove 302 is less than or equal to the thickness of the corresponding belt.

[0108] In practical applications, such asFigure 6 , 7 As shown in Figure 8, the depth of the annular mounting groove 302 can also be greater than the thickness of the corresponding belt. In this case, the side of the foot pedal 35 facing the first belt 312 has an avoidance recess 35a, and the side wall of the annular mounting groove 302 is embedded in the corresponding avoidance recess 35a.

[0109] When subjected to exceptionally large lateral forces, the belt risks detaching from the annular mounting groove 302. Through design, the depth of the annular mounting groove 302 is greater than the thickness of the corresponding belt, which better prevents belt derailment compared to a flush design. Furthermore, an avoidance notch 35a on the side of the foot pedal 35 facing the first belt 312 effectively prevents interference. In actual use, the avoidance notch 35a does not contact the sidewall of the annular mounting groove 302, thus preventing additional noise.

[0110] like Figure 5 As shown, in this embodiment, the plastic body 351 has an insert groove 3512, and the metal part 352 is fixed in the insert groove 3512 of the plastic body 351 by fasteners 36; or, the plastic body 351 is directly covered on the outside of the metal part 352 by injection molding.

[0111] like Figure 3 and 4 As shown, roller 301 is a bearing. In practical applications, roller 301 can also be a wheel with a bearing installed in the middle.

[0112] like Figure 1 and 2 As shown, in this embodiment, the length direction of the foot pedal 35 is the same as the length direction of the front axle 11;

[0113] like Figure 3 and 4 As shown, the first support frame 313 is located inside the first belt 312, the second support frame 323 is located inside the second belt 322, and the intermediate support frame 333 is located inside the intermediate belt 332.

[0114] like Figure 1 and 2 As shown, in this embodiment, the two ends of the foot pedal 35 are fixed to the first belt 312 and the second belt 322 respectively by fasteners 36.

[0115] In actual pre-compression, the middle part of the foot pedal strip 35 may not be fixed to the intermediate belt 332, or it may be fixed to the intermediate belt 332 by fastener 36.

[0116] like Figure 1 and 9 As shown, the upper end of the vertical frame 2 has a crossbeam 21, such as... Figures 9 to 16 As shown, the braking mechanism 4 includes:

[0117] The brake wheel is fixed on the front axle 11. The brake wheel is made of metal. Preferably, the brake wheel is a first pulley 311 fixed on the front axle 11 or / and a second pulley 321 fixed on the front axle 11. This arrangement can save parts. In actual use, an independent brake wheel can also be set.

[0118] The movable block 42 is movably mounted on the base 1, and a plurality of strong magnets 421 are fixed to the end of the movable block 42 facing the brake wheel.

[0119] An elastic element 43 is disposed between the base 1 and the movable block 42, and is used to give the movable block 42 a tendency to move toward the brake wheel side;

[0120] The first rotating component 44 is rotatably mounted on the vertical frame 2;

[0121] Positioning element 45 is disposed on vertical frame 2 and cooperates with first rotating member 44 to position first rotating member 44 at a set angle.

[0122] The first metal wire 46 has one end wound around the first rotating member 44 and the other end connected to the moving block 42. The first rotating member 44 can pull the first metal wire 46, thereby moving the moving block 42.

[0123] The working principle of the braking mechanism 4 in this application is as follows: the brake wheel is fixed on the front axle 11 and can rotate with the front axle 11. When the moving block 42 approaches the brake wheel, the strong magnet 421 approaches the brake wheel, and a force that prevents the brake wheel from rotating can be formed between the brake wheel and the strong magnet 421. The closer to the brake wheel, the stronger this braking force. The braking mechanism 4 of this application can pull the first metal wire 46 by rotating the first rotating member 44, thereby controlling the distance between the strong magnet 421 and the brake wheel, controlling the braking force. The positioning element 45 can keep the first rotating member 44 at a set angle, and at the same time, it can realize the gear adjustment function of the treadmill. This application uses the first rotating member 44 to control the brake, which is convenient and quick to operate.

[0124] When the first rotating member 44 is rotated to loosen the first metal wire 46, the moving block 42 moves closer to the brake wheel under the action of the elastic member 43. When the first rotating member 44 is rotated to further wind the first metal wire 46, the first metal wire 46 overcomes the elastic force of the elastic member 43 and moves away from the brake wheel.

[0125] like Figures 9 to 16 As shown, in this embodiment, both the first rotating member 44 and the positioning element 45 are disposed on the crossbeam 21;

[0126] There are two brake wheels, which are respectively located on the left and right sides of the front axle 11 (i.e., the first pulley 311 fixed on the front axle 11 and the second pulley 321 fixed on the front axle 11); there are also two moving blocks 42 and two first metal wires 46. The two moving blocks 42 are respectively matched with the two brake wheels. One end of each of the two first metal wires 46 is wound around the first rotating member 44. When the first rotating member 44 is rotated, it can drive the two first metal wires 46 to wind or release synchronously.

[0127] The brake wheels are respectively set on the left and right sides of the front axle 11, and the two first metal wires 46 are both wound around the first rotating part 44. When the first rotating part 44 is rotated, the two first metal wires 46 can be wound or released synchronously, which can achieve simultaneous braking on both sides of the front axle 11, with uniform braking force, good force distribution effect, and high reliability in long-term use.

[0128] like Figure 14 and 16 As shown, in this embodiment, the first rotating member 44 has a first winding portion 441 and a positioning portion 442. One end of each of the two first metal wires 46 is wound around the first winding portion 441. The positioning portion 442 has a plurality of positioning grooves 4421 distributed around the axis of the first rotating member 44. The positioning element 45 is an elastic pin installed on the crossbeam 21. The elastic pin is used to extend into the positioning groove 4421.

[0129] Self-positioning is achieved by extending an elastic pin into the positioning groove 4421. When braking is required, the first rotating member 44 is rotated, and torque is applied to overcome the force between the elastic pin and the positioning groove 4421, causing the positioning pin to retract. Thus, the first rotating member 44 rotates normally, and when it rotates to the appropriate position, the positioning pin resets and can be repositioned.

[0130] like Figure 14 and 16 As shown, in this embodiment, the first rotating member 44 also includes a first control knob 443 located outside the crossbeam 21.

[0131] like Figure 14 and 16 As shown, in this embodiment, one end of the elastic pin is the mounting end and the other end is the elastic mating end. The mounting end of the elastic pin is screwed onto the crossbeam 21, and the elastic mating end of the elastic pin mates with the positioning groove 4421.

[0132] This design facilitates installation and debugging, and the distance between the elastic mating end and the positioning groove 4421 can be quickly adjusted by rotating the elastic pin.

[0133] like Figure 10 As shown, in this embodiment, each strong magnet 421 is distributed in a manner that is low in the middle and high on both sides.

[0134] like Figure 10 and 12 As shown, in this embodiment, the base 1 has a mounting plate 13;

[0135] The movable block 42 has a screw 422 and a guide rod 423 arranged in parallel. There is at least one guide rod 423. The guide rod 423 and the screw 422 are slidably arranged on the mounting plate 13.

[0136] The elastic element 43 is a compression spring, and the elastic element 43 is sleeved on the screw 422 and / or the guide rod 423;

[0137] The braking mechanism 4 also includes a limiting nut 47, which is screwed onto the screw 422 and abuts against the mounting plate 13. The limiting nut 47 is used to limit the position of the moving block 42 closest to the brake wheel.

[0138] Compared to a rotational configuration, this arrangement of the moving block 42 results in a more even distribution of the strong magnets 421, leading to better braking.

[0139] like Figure 10 and 12 As shown, in this embodiment, the brake wheel is made of iron, and the outer side of the brake wheel has a protective layer 41 that cannot be attracted by a magnet.

[0140] In this application, the movable block 42 can contact the protective layer 41, and the protective layer 41 cannot be attracted by the magnet, thereby limiting the minimum distance between the brake wheel and the strong magnet 421, thus avoiding the problem of the strong magnet 421 coming into direct contact with the iron (distance is 0), which would make separation difficult.

[0141] In practical applications, the protective layer 41 can be an aluminum layer.

[0142] like Figure 10 , 12 As shown in Figure 16, in this embodiment, the brake mechanism 4 further includes a first threaded sleeve 48, one end of which is fixed on the base 1 and the other end is fixed on the crossbeam 21. A first metal wire 46 is threaded through the first threaded sleeve 48 and both ends of the first metal wire 46 pass through the first threaded sleeve 48.

[0143] like Figures 17 to 24 As shown, the slope adjustment mechanism of this embodiment includes two sets of support adjustment components 51 and a control component 52 for controlling the two sets of support adjustment components 51:

[0144] like Figure 22 and 23 As shown, the control assembly 52 includes a second rotating member 521 mounted on the vertical frame 2 and a bidirectional ratchet structure 522, which can switch the unidirectional rotation direction of the second rotating member 521.

[0145] likeFigures 17 to 20 As shown, two sets of support adjustment components 51 are respectively arranged on the left and right sides of the front end of the base 1. Each set of support adjustment components 51 includes:

[0146] A support adjustment frame 511 is rotatably mounted on the base 1 at its center. One end of the support adjustment frame 511 is a tension end 5111, and the other end is a support end 5112, which is used to contact the ground.

[0147] The second metal wire 512 has one end connected to the tension end 5111 and the other end wrapped around the rotating part.

[0148] When the second rotating component 521 of the control component 52 rotates, it can drive the two second metal wires 512 to wind or release synchronously.

[0149] This application utilizes the rotation of the second rotating member 521 to drive the second metal wire 512 to synchronously wind or release. During synchronous winding, the second metal wire 512 pulls the tension end 5111 of the support adjustment frame 511, causing the support end 5112 to rotate downwards, the front end of the base 1 to move upwards, and the slope to increase. (See...) Figure 24 When released synchronously, the support adjustment frame 511 rotates under gravity, the support end 5112 moves upward, and the front end of the base 1 moves downward, reducing the slope. The control component 52 can switch the unidirectional rotation direction of the second rotating component 521 through the bidirectional ratchet structure 522, that is, it can control whether the slope is adjusted upward or downward, and can be positioned after adjustment. This application can achieve more levels of adjustment through the ratchet structure, and the control component 52 is set on the vertical frame 2, which is convenient to operate and does not require a person to squat down for adjustment.

[0150] like Figure 22 and 23 As shown, in this embodiment, the bidirectional ratchet structure 522 includes:

[0151] Gear 5221 is fixed on the second rotating component 521;

[0152] Two ratchet teeth are rotatably mounted on the vertical frame 2. The two ratchet teeth are the first ratchet tooth 5222 and the second ratchet tooth 5223. When the first ratchet tooth 5222 is engaged with the gear 5221, the second rotating member 521 can rotate around the first direction but cannot rotate around the second direction. When the second ratchet tooth 5223 is engaged with the gear 5221, the second rotating member 521 can rotate around the second direction but cannot rotate around the first direction. The first direction and the second direction are opposite.

[0153] Two elastic reset elements (omitted in the figure) engage with two ratchet teeth respectively, which are used to make the corresponding ratchet teeth have a tendency to rotate toward the gear 5221.

[0154] The control element 5224 is rotatably mounted on the vertical frame 2 and located between the two ratchet teeth. The control element 5224 has a drive part 52241 that engages with the ratchet teeth. The control element 5224 is used to make one of the two ratchet teeth engage with the gear 5221.

[0155] By rotating the control component 5224, the drive unit 52241 can be moved, thus allowing it to selectively engage with either the first ratchet 5222 or the second ratchet 5223. When the drive unit 52241 engages with the first ratchet 5222, the drive unit 52241 disengages the first ratchet 5222 from the gear 5221, while the second ratchet 5223 engages with the gear 5221 under the action of the corresponding elastic reset component. When the drive unit 52241 engages with the second ratchet 5223, the drive unit 52241 disengages the second ratchet 5223 from the gear 5221, while the first ratchet 5222 engages with the gear 5221 under the action of the corresponding elastic reset component. By controlling the control component 5224, the unidirectional rotation direction of the second rotating component 521 can be switched, thereby achieving the switching between slope increase and slope decrease modes.

[0156] In practical applications, the elastic reset element can be in the form of a compression spring, tension spring, torsion spring, or spring sheet.

[0157] like Figure 21 , 22 As shown in Figures 23 and 24, in this embodiment, the control component 52 is disposed on the crossbeam 21.

[0158] like Figure 22 and 23 As shown, in this embodiment, the second rotating member 521 has a second winding portion 5211, and one end of each of the two second metal wires 512 is wound around the second winding portion 5211.

[0159] like Figure 18 and 20 As shown, in this embodiment, the support adjustment assembly 51 also includes a guide wheel assembly fixed on the base 1, and the second metal wire 512 passes around the guide wheel assembly;

[0160] The guide wheel assembly includes a lower guide wheel 53 and an upper guide wheel 54 located above the lower guide wheel 53, with the upper guide wheel 54 located above the tension end 5111.

[0161] The guide wheel assembly can guide the second metal wire 512. The upper guide wheel 54 is located above the tension end 5111, which can make the second metal wire 512 better pull the support adjustment frame 511.

[0162] like Figure 18 , 20 As shown in Figures 2 and 24, in this embodiment, a support wheel 5113 is installed on the support end 5112.

[0163] The support wheel 5113 is provided to facilitate the rotation adjustment of the support adjustment frame 511.

[0164] like Figure 1 , 22 As shown in Figures 2 and 23, in this embodiment, the control component 52 further includes a second control knob 523 that is circumferentially fixed to the second rotating member 521.

[0165] like Figure 25 and 26 As shown, in actual use, the second control knob 523 has a mating hole 5231; the control assembly 52 also includes an assist rod 524 whose end can be inserted into the mating hole 5231.

[0166] In practical applications, to reduce the adjustment torque, the user can adjust the mechanism after getting off the treadmill. Alternatively, the user can adjust the mechanism while standing on the treadmill. To achieve better rotation, a detachable assist rod 524 is used to increase the lever arm, ensuring reliable rotation of the second rotating component 521.

[0167] In practical applications, the base 1 or the vertical frame 2 has a receiving groove (not shown in the figure) for accommodating the assist rod 524.

[0168] like Figure 18 , 20 As shown in Figure 23, in this embodiment, the brake mechanism 4 further includes a second threaded sleeve 513. One end of the second threaded sleeve 513 is defined on the base 1, and the other end is defined on the crossbeam 21. A second metal wire 512 is threaded through the second threaded sleeve 513, and both ends of the second metal wire 512 pass through the second threaded sleeve 513.

[0169] In this application, "walking machine" is a broad term, and "treadmill" is also a type of walking machine mentioned in this application.
