Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically a manually adjustable negative angle structure for a treadmill and a treadmill. Background Technology

[0002] Treadmills are commonly used fitness equipment in homes and gyms. To meet market demand, treadmills have also developed incline simulation functions. For example, a treadmill with publication number CN108339230A includes a frame unit, a running belt, and a front lifting unit. The front lifting unit is mounted on the base frame and can drive the front end of the base frame to rise and fall. The front lifting unit includes a rotatable front actuator mounted between a front pivot and a rear pivot, a front connecting rod driven by the front actuator to move relative to the base frame, a pair of front connecting rods respectively connected to the front connecting rods and located on the outside of the base frame, a rotatable front pivot rod pivoted on the base frame, and a pair of front support rods connected to the front pivot rods and located on the outside of the base frame. Each front connecting rod has a first front end connected to the front connecting rod and a second front end opposite to the first front end and pivotally connected to the front support rod. The front support rods are close to the front end and each has a front pivot end connected to the front pivot rod and a front swing end opposite to the front pivot end. The second front end of the front connecting rod is pivotally connected between the front pivot end and the front swing end. This treadmill uses a front lifting unit to raise the front of the treadmill to simulate an uphill situation, allowing users to exercise uphill. However, running encounters diverse terrains, including both uphill and downhill sections. Downhill sections tend to accelerate quickly, making braking difficult. Therefore, downhill training is also essential. This treadmill lacks downhill training capabilities, has limited training functions, and has a complex structure, resulting in a higher cost.

[0022] 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] See Figures 1-4 A manually adjustable negative angle structure for a treadmill includes a movable plate 1, a rotating shaft 2, and a pin 3. One end of the movable plate 1 is provided with a rotating hole, and the other end is provided with multiple insertion holes 4. The multiple insertion holes 4 are arranged side by side. The rotating shaft 2 passes through the rotating hole and is connected to the rear end of the bottom of the treadmill. The pin 3 passes through the insertion hole 4 and abuts against the bottom of the treadmill.

[0024] In use, the movable plate 1 is rotated to a certain angle around the pivot 2, and the pin 3 is inserted into the socket 4 with the end of the pin 3 extending out of the socket 4. The bottom of the treadmill abuts against the pin 3 to fix the treadmill in place. Specifically, when the movable plate 1 is rotated to a horizontal angle, the treadmill is in a horizontal state after the pin 3 is inserted into the socket 4, which is used for users to exercise on an incline. When the movable plate 1 is rotated to a positive angle, the treadmill is in an uphill state after the pin 3 is inserted into the socket 4, which is used for users to exercise on an incline. When the movable plate 1 is rotated to a negative angle, the treadmill is in a downhill state after the pin 3 is inserted into the socket 4, which is used for users to exercise on a downhill. It has multiple exercise modes, more complete functions, and a simple structure, which makes the angle adjustment of the treadmill possible.
