Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to an adjustable treadmill. Background Technology

[0002] Treadmills are indoor fitness equipment that simulates outdoor running and walking. They are mainly used for aerobic training and help users exercise in a fixed space. Their main structure includes a rotating running belt, a power drive system, a control panel, and safety devices. They can adapt to different exercise intensities and meet the needs of daily fitness, weight loss, and endurance improvement. They are widely used in homes, gyms, and other settings.

[0003] Mainstream electric treadmills use an electric motor as their core power source. The motor drives the front and rear rollers to rotate, which in turn drives the running belt to move in a cycle, simulating the relative motion of the ground when running outdoors. Users set the speed and incline through the control panel, and the motor adjusts its speed according to the instructions to control the speed of the running belt.

[0004] When the incline of an existing treadmill is adjusted, the running belt area where the user stands will rise synchronously with the incline adjustment. However, the control panel on the existing treadmill is fixedly installed. This means that after the user is raised, the control panel cannot adjust the tilt angle to adapt to the user. As a result, the user cannot clearly observe the control panel to control the speed, incline, etc., which is quite inconvenient to use. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This invention provides an adjustable treadmill. It has the following beneficial effects:

[0019] 1. By pressing the pressure plates on both sides, the pressure plates are driven to abut against the outer surface of the mounting block, thereby ensuring that the moving gear ring and the fixed gear ring are separated. At this time, the control panel can be moved to adjust the angle of the control panel. Releasing the pressure plates will cause the moving gear ring to move under the action of the compression spring, so as to cooperate with the fixed gear ring and lock the rotation angle. This makes it convenient to adjust the angle of the control panel and easy for the user to observe.

[0020] 2. Start the geared motor. The geared motor drives the bidirectional threaded rod to rotate through the cooperation of the worm gear and worm. This causes the two threaded sleeves to move in opposite directions on the outer surface of the bidirectional threaded rod, so that the two threaded sleeves move toward the two ends of the bidirectional threaded rod. This synchronously drives the rotating rod to rotate, thereby lifting the end of the moving part close to the frame. This allows for easy adjustment of the slope of the moving part. Furthermore, the stability of the moving part is ensured by the rotating rods at both ends and the I-shaped insert plates. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides an adjustable treadmill with a frame 2 and a motion component 1 at the bottom of the frame 2.

[0032] The control component 3 is located on the top of the frame 2. The control component 3 includes a fixed base 309 fixedly installed on the top of the frame 2. A fixed cylinder 305 is fixedly installed inside the fixed base 309. A movable shaft 304 is inserted into both ends of the fixed cylinder 305. A movable gear ring 307 is installed on the outer surface of the movable shaft 304. A compression spring 306 is installed between the movable gear ring 307 and the fixed cylinder 305. A mounting block 302 is movably installed on the outer surface of the end of the movable shaft 304 away from the fixed base 309. A fixed gear ring 303 is installed on the side of the mounting block 302 near the movable gear ring 307. A control panel 301 is installed on the end of the mounting block 302 away from the fixed base 309.

[0033] like Figure 2 In this embodiment, a keyway is provided on the outer surface of the movable shaft 304, and a flat key matching the keyway is provided inside the fixed cylinder 305. By setting the flat key and the keyway, the movable shaft 304 is prevented from driving the movable gear ring 307 to rotate, thereby ensuring the cooperation between the movable gear ring 307 and the fixed gear ring 303, and limiting the mounting block 302 from driving the control panel 301 to rotate.

[0034] like Figure 2 In this embodiment, the fixed base 309 has a through hole inside, the movable gear ring 307 is disposed inside the through hole, and the fixed gear ring 303 is inserted into the through hole. The mounting block 302 and the fixed gear ring 303 both have round holes that cooperate with the movable shaft 304. The cooperation between the movable shaft 304 and the round hole inside the mounting block 302 ensures that the mounting block 302 can rotate stably. The movable gear ring 307 is inserted into the through hole, so that the cooperation between the movable gear ring 307 and the inside of the through hole can help limit the rotation of the mounting block 302 around the axis of the through hole. After the fixed gear ring 303 is inserted into the through hole, it can cooperate with the movable gear ring 307, thereby ensuring stable locking.

[0035] like Figure 2 In this embodiment, the end of the movable shaft 304 away from the fixed base 309 passes through the round hole inside the mounting block 302 and is fitted with a pressure plate 308. The pressure plate 308 facilitates pressing the movable shaft 304 and prevents the movable shaft 304 from detaching from the mounting block 302 when it is retracted.

[0036] Furthermore, teeth are provided on the adjacent surfaces of both the movable gear ring 307 and the fixed gear ring 303. These teeth prevent the fixed gear ring 303 from rotating when engaged with the movable gear ring 307. By pressing the pressure plates 308 on both sides, the pressure plates 308 abut against the outer surface of the mounting block 302, thus ensuring the separation of the movable gear ring 307 from the fixed gear ring 303. At this point, the control panel 301 can be moved to adjust its angle. After adjusting to the appropriate angle, the pressure plates 308 are released, and the movable gear ring 307 moves under the action of the compression spring 306. The movable gear ring 307 then drives the movable shaft 304 to extend outwards. After moving, the movable gear ring 307 engages with the fixed gear ring 303 to lock the rotation angle. The connection relationship, working principle, and operating sequence between the control panel 301 and other components are existing technologies and are common knowledge well-known to those skilled in the art; therefore, they will not be elaborated upon here.

[0037] Example 2

[0038] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The lifting component 4 is set at the bottom of the frame 2. The lifting component 4 includes a fixed frame 402 fixedly installed at the bottom of the frame 2. A bidirectional threaded rod 404 is provided inside the fixed frame 402. Two threaded sleeves 405 are engaged with the outer surface of the bidirectional threaded rod 404. A rotating rod 406 is hinged above the threaded sleeves 405. The top end of the rotating rod 406 passes through the fixed frame 402 and is hinged to the lower surface of the moving part 1.

[0039] like Figure 3 as well as Figure 4 In this embodiment, both ends of the bidirectional threaded rod 404 pass through the outer surface of the frame 2. The outer surfaces of both ends of the bidirectional threaded rod 404 are movably connected to the outer surface of the frame 2 through bearings. A geared motor 409 is installed inside the frame 2. A worm gear 408 is installed at the output end of the geared motor 409. A worm wheel 407 is installed on the outer surface of the end of the bidirectional threaded rod 404 near the geared motor 409. The worm gear 408 and the worm wheel 407 are meshed together.

[0040] like Figure 3 as well as Figure 6In this embodiment, a base plate 401 is installed below the fixed frame 402. A pulley is provided at the bottom of the end of the moving part 1 away from the frame 2. An I-shaped insert plate 403 is hinged to the bottom of the end of the moving part 1 away from the frame 2. An insertion hole that mates with the I-shaped insert plate 403 is opened on the outer surface of the base plate 401. By setting the pulley, when the moving part 1 is lifted, the end of the moving part 1 away from the frame 2 can slide on the ground through the pulley, thereby ensuring stable lifting and assisting the insertion of the I-shaped insert plate 403 and the base plate 401, thereby improving stability.

[0041] Furthermore, the geared motor 409 is started. Through the cooperation of the worm gear 407 and the worm 408, the geared motor 409 drives the bidirectional threaded rod 404 to rotate, which in turn drives the two threaded sleeves 405 to move in opposite directions on the outer surface of the bidirectional threaded rod 404. This causes the two threaded sleeves 405 to move toward both ends of the bidirectional threaded rod 404, thereby synchronously driving the rotating rod 406 to rotate. This lifts the end of the moving part 1 that is close to the frame 2, thereby adjusting the slope of the moving part 1. The connection relationship, working principle and operation sequence between the moving part 1 and other components are common knowledge known to those skilled in the art and will not be elaborated further here.

[0042] Working Principle: When using the treadmill, the user selects a suitable incline via the control panel 301, which activates the reduction motor 409. The reduction motor 409, through the cooperation of the worm gear 407 and worm 408, drives the bidirectional threaded rod 404 to rotate. This, in turn, causes the two threaded sleeves 405 to move back-to-back on the outer surface of the bidirectional threaded rod 404, moving them towards both ends of the rod. This synchronously drives the rotating rod 406 to rotate, thereby raising the end of the moving part 1 closest to the frame 2 and adjusting the incline of the moving part 1. The specific rotation angle depends on the incline selected by the user. The moving part 1 can rotate up to a maximum incline of 15%, at which point the rotating rod 406 rotates to a vertical position. The rotating rod 406 is positioned on the moving part 1 closest to the frame 2. The two sides of the bottom end are designed to provide stable support for the moving part 1. After the slope adjustment is completed, the angle of the control panel 301 can be adjusted according to the user's needs. By pressing the pressure plates 308 on both sides, the pressure plates 308 are driven to abut against the outer surface of the mounting block 302, thereby ensuring that the moving gear ring 307 is separated from the fixed gear ring 303. At this time, the control panel 301 can be moved to adjust its angle. After adjusting to the appropriate angle, the pressure plates 308 are released. Under the action of the compression spring 306, the moving gear ring 307 is driven to move. The moving gear ring 307 drives the moving shaft 304 to extend outward. After the moving gear ring 307 moves, it cooperates with the fixed gear ring 303 to lock the rotation angle, thus completing the adjustment of the treadmill for user convenience.
