Description

Technical Field

[0001] This utility model relates to the field of treadmill technology, specifically to an incline adjustment device for treadmills. Background Technology

[0002] When running outdoors, people encounter different terrains, such as flat ground, uphill, and downhill. To simulate these real-world scenarios on indoor treadmills and increase the fun and challenge of running, incline adjustment devices have been developed. By adjusting the incline, users can experience the feeling of running on different terrains such as mountain trails and slopes, making the workout more diverse and enjoyable.

[0003] Existing devices primarily simulate incline sections by adjusting the height of one end of the running platform. Current technology is largely similar to a manual incline adjustment device for an electric treadmill, as disclosed in CN206198552U. This incline adjuster has a U-shaped upper section that supports the running platform. The running platform's side tubes are housed within the U-shaped structure at the top of the incline adjuster. At least one side of the U-shaped structure at the top of the incline adjuster is connected to the running platform's side tubes via a horizontal pivot. This invention utilizes an incline adjuster to change the height of the rear of the running platform to achieve incline adjustment. It has advantages such as fewer parts, simple assembly, and low cost, while also being simple, practical, and easy to operate. However, there are still areas for improvement in this device.

[0004] Existing devices mainly adjust the incline by lifting one end of the running platform. This makes it difficult for some devices to stably support the hollow running platform, which makes it inconvenient for the running platform to simulate uphill and downhill roads. At the same time, some devices have difficulty smoothly connecting the height difference between the base and the running platform, which makes it easy for users to fall off the running platform due to exhaustion, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, an incline adjustment device for treadmills is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an incline adjustment device for treadmills, in order to solve the problem mentioned in the background art that the existing devices mainly adjust the incline by lifting one end of the running platform, which makes it difficult for some devices to stably support the hollow running platform, thus making it inconvenient for the running platform to simulate uphill and downhill roads. At the same time, some devices are difficult to smoothly connect the height difference between the base and the running platform, thus causing users to easily fall off the running platform due to exhaustion.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a treadmill incline adjustment device, comprising a base, a support platform fixedly connected to the top right side of the base, an arc-shaped gimbal movably mounted on the inner wall of the support platform, a running platform fixedly connected to the top of the arc-shaped gimbal, a fixed frame fixedly connected to the middle of the support platform, a handrail fixedly connected to the top right end of the base, a CNC console fixedly connected to the top right side of the handrail, an adjustment mechanism provided inside the fixed frame, the adjustment mechanism including a servo motor, the rear side of the servo motor fixedly connected to the front right side of the fixed frame, and an anti-fall mechanism provided on the left side of the base.

[0007] Preferably, the front and rear sides of the support are fixedly connected to a limiting wheel frame, and the outer wall of the roller of the limiting wheel frame is in close contact with the inner wall of the arc gimbal.

[0008] Preferably, a transmission worm gear is fixedly connected to the middle of the rear side of the servo motor, and the rear end of the transmission worm gear is movably connected to the rear side of the inner wall of the fixed frame.

[0009] Preferably, a transmission worm wheel is meshed with the lower outer wall of the transmission worm, and an adjusting screw is fixedly connected to the inner wall of the transmission worm wheel.

[0010] Preferably, the two ends of the adjusting screw are movably connected to the two sides of the inner wall of the fixed frame, and the left side of the outer wall of the adjusting screw is threaded with an adjusting sleeve.

[0011] Preferably, a traction rod is movably connected to the upper part of the outer wall of the adjusting screw sleeve, and the top end of the traction rod is movably connected to the bottom right side of the running platform.

[0012] Preferably, the fall prevention mechanism includes a movable step, the right side of which is movably connected to the left side of the running platform, and a pulley is movably connected to the left side of which is movable step.

[0013] Preferably, the outer wall of the pulley is provided with a limiting groove, and the bottom of the limiting groove is fixedly connected to the top left side of the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a support platform, a limiting wheel frame, and an arc gimbal to limit the sliding of the arc gimbal on the inner wall of the support platform. This allows the arc gimbal to drive the running platform to rotate in a limited manner, so that the support platform can work with the arc gimbal to stably support the running platform. This effectively avoids the hollow support running platform from deforming under stress, thus improving the stability and practicality of the device.

[0016] 2. This utility model utilizes a servo motor, transmission worm gear, transmission worm wheel, adjusting screw, adjusting sleeve, and traction rod in its adjustment mechanism. The servo motor, activated by a CNC console, drives the transmission worm gear to rotate in a limited position. The transmission worm gear meshes with and drives the transmission worm wheel and adjusting screw to rotate in a limited position. This causes the adjusting screw to slide left and right along the left and right sides of the adjusting sleeve and traction rod, while the right side of the traction rod drives the running platform to rotate in a limited position. This allows for adjustment of the running platform's tilt angle in some parts of the device, facilitating the simulation of uphill and downhill slopes and improving the device's adjustability and practicality.

[0017] 3. This utility model, through the structure of movable ladder plate, pulley and limiting groove in the anti-fall mechanism, drives the running platform to rotate in a limiting manner through the adjustment mechanism. The running platform drives the right end of the movable ladder plate to rotate synchronously, and the left end of the movable ladder plate drives the pulley to slide in the limiting groove in a limiting manner, thereby realizing the anti-fall of the running platform. It also allows some devices to connect the base and the running platform through the height difference of the movable ladder plate, effectively preventing the user from falling off the running platform due to exhaustion, thus improving the protective and practical functions of the device.

Through this design, the servo motor 21 drives the transmission worm gear 22 to rotate in a limited position. A transmission worm wheel 23 is meshed with the lower outer wall of the transmission worm gear 22. An adjustment screw 24 is fixedly connected to the inner wall of the transmission worm wheel 23. Through this design, the transmission worm gear 22 meshes with the adjustment screw 24. The drive worm gear 23 and adjusting screw 24 rotate together. The two ends of the adjusting screw 24 are movably connected to the two sides of the inner wall of the fixed frame 16. The left side of the outer wall of the adjusting screw 24 is threaded with an adjusting sleeve 25. Through this design, the adjusting screw 24 drives the adjusting sleeve 25 to slide left and right. The upper part of the outer wall of the adjusting sleeve 25 is movably connected to a traction rod 26.
