Description

Technical Field

[0001] This utility model relates to the field of treadmills, specifically to a treadmill incline adjustment structure. Background Technology

[0002] As a popular fitness machine, convenience is a key feature of treadmills. When running on a road, people rely on the friction between their feet and the ground to propel themselves forward. However, on a treadmill, the running belt rotates, and the user remains in place, eliminating the need for pushing off. Therefore, an appropriate incline is needed to compensate for the backward force of the feet. Consequently, most treadmills are equipped with incline adjustment mechanisms to customize the slope according to different workout intensities. However, current treadmill incline adjustment mechanisms are generally complex and costly to produce, especially those driven by motors, which are often bulky and inconvenient to store and transport.

[0005] Furthermore, the support block is an obtuse triangle.

[0006] Furthermore, the main support is provided with threaded tube A and threaded tube B, and threaded tube A and threaded tube B are provided with internal threads.

[0007] Furthermore, one end of the limiting pin is provided with an external thread, and the other end is provided with a limiting part, and the limiting pin is threadedly connected to the threaded pipe A.

[0008] Furthermore, one end of the fastening bolt is provided with an external thread, and the other end is provided with a handle. A connecting part is provided between the handle and the external thread. The fastening bolt is threadedly connected to the threaded pipe B. After connection, the side of the connecting part abuts against the side of the adjustment hole of the support block.

[0009] Furthermore, a sleeve is provided on the support block on one side of the limiting hole, and the sleeve is sleeved on the threaded pipe A.

[0010] Furthermore, a reinforcing rib is provided around the support block, and a reinforcing part is provided around the adjustment hole of the support block.

[0011] Compared with the prior art, the advantages of this utility model are: the treadmill incline adjustment structure is simple in structure and low in production cost; it is lightweight and small in size, making it easy to store and transport; it is simple to operate, not prone to misoperation, and has a stable locking effect.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0017] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "bottom", "top", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and 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 utility model.

[0018] The treadmill incline adjustment structure provided in this embodiment is respectively set on the left and right sides of the treadmill, including a main support frame 1, threaded pipe A2, threaded pipe B3, support block 4, fastening bolt 5, and limiting pin 6. Threaded pipe A2 and threaded pipe B3 are provided with internal threads and are welded and fixed to the main support frame 1 of the treadmill (or threaded holes can be directly provided on the main support frame 1). The support block 4 is preferably an obtuse triangle, with a limiting hole 8 at one end and several adjustment holes 7. A sleeve part 9 is also provided on one side of the support block 4 near the limiting hole 8. The sleeve part 9 is sleeved onto the threaded pipe A2, which strengthens the support force and facilitates the rotation of the support block 4. A reinforcing rib 10 is provided around the perimeter, and a reinforcing part 11 is provided around the adjusting hole 7. The reinforcing rib 10 and the reinforcing part 11 can increase strength and reduce material usage. One end of the fastening bolt 5 is provided with an external thread, and the other end is provided with a handle 12. A connecting part 13 is provided between the handle 12 and the external thread. The external thread end of the fastening bolt 5 passes through the adjusting hole 7 and is screwed to the threaded tube B3. After connection, the side of the connecting part 13 abuts against the side of the adjusting hole 7 of the support block 4 to limit the rotation of the support block 4. One end of the limiting pin 6 is provided with an external thread, and the other end is provided with a limiting part. The limiting pin 6 passes through the limiting hole 8 and is screwed to the threaded tube A2. After connection, the limiting part abuts against the side of the limiting hole 8 of the support block 4, and the support block 4 can rotate with the threaded tube A2 (limiting hole 8) as the center.

[0019] The treadmill incline adjustment structure provided in this embodiment allows for the following operation: When using the treadmill, tilt it to the side, unscrew the fastening bolt 5 using the handle 12, rotate the support block 4 to adjust the adjustment hole 7 of the support block 4 to a suitable angle, and then tighten the fastening bolt 5 to secure it. The operation is the same on the other side. When storing the treadmill, tilt it to the side, unscrew the fastening bolt 5, rotate the support block 4 to adjust the adjustment hole 7 at the bottom of the support block 4 to the position of the threaded tube B3, and then tighten the fastening bolt 5 to secure it.
