Description

Technical Field

[0001] This utility model relates to the field of treadmill technology, to folding treadmills, and particularly to an anti-tilting structure for folding treadmills. Background Technology

[0002] A walking machine is a type of fitness equipment that mainly consists of a platform with a conveyor belt (similar to the running belt part of a treadmill). For ease of storage and movement, some walking machines have a foldable design.

[0003] For example, the patent application number CN202110133442.3 provides a foldable frame structure and fitness equipment, including two frames rotatably connected, a rotating shaft rotatably installed at the ends of the frames, a running board fixed one-to-one on the frames, and a running belt wrapped around the rotating shaft and the running board with the rotating shaft at both ends as the base point.

[0004] However, because the frame with the running board is fixed in a rotating connection, when the frame is flat on the ground, a person walking or running on the running belt will cause the frame and running board in contact with the ground to bear downward pressure. When the frame is in contact with the ground, the ground will have an upward reaction force on the frame and running board, causing the two frames to rotate, that is, the running board will tilt up, creating a certain safety hazard. Utility Model Content

[0005] This invention addresses the problem of the running board tilting upwards in folding treadmills. The technical problem this invention aims to solve is to provide an anti-tilting structure for folding treadmills that is easy to operate and can prevent the running board from tilting upwards.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: the anti-tilting structure of the folding treadmill, including frame one and frame two rotatably connected, frame one and frame two can be rotated to be horizontal and distributed left and right or stacked up and down. The first frame is provided with a hook on its side, and the second frame is provided with a hook ring on its side that can hook with the hook. When the hook ring hooks with the hook, the ends of the first frame and the second frame abut against each other and the rotation between the first frame and the second frame is restricted. The hook ring and the hook generate a pulling force toward the two ends of the first frame and the second frame that are far apart.

[0007] A further preferred embodiment of this utility model is that the rotation axes between frame one and frame two are distributed front and back, and the tensile force is directed towards the left and right ends.

[0008] A further preferred embodiment of this utility model is: the hook is fixed or integrally disposed above the frame, and the hook ring is rotatably or fixedly connected or integrally disposed on the second frame.

[0009] A further preferred embodiment of this utility model is: the first frame and the second frame are provided with protruding mounting parts, and hinges are fixedly connected to the mounting parts of the first frame and the second frame.

[0010] A further preferred embodiment of this utility model is: the mounting part is provided on the upper end surface of frame one or frame two and protrudes outwards; a running plate is fixed on frame one and frame two, and the running plate avoids the mounting part and the hinge.

[0011] A further preferred embodiment of this utility model is: an clearance opening is provided on the running board, the mounting part and the hinge are located in the clearance opening, and the mounting part and the hinge are flush with or lower than the upper surface of the running board.

[0012] A further preferred embodiment of this utility model is: an annular closed running belt is installed on the first frame and the second frame, and the clearance opening is located on both sides of the running belt.

[0013] A further preferred embodiment of this utility model is: a cover plate is fixed on the first frame and the second frame, and the cover plate covers the avoidance opening.

[0014] Compared with the prior art, the advantages of this utility model are that by hooking the hook ring and hook piece and generating a pulling force on the hinged frame one and frame two to both ends, a tension structure is formed, which makes the hinged frame one and frame two have high impact resistance and stability, effectively preventing the running board from tilting up due to external forces or other factors, maintaining the stability of the overall structure of the walking machine, and improving the safety of the walking machine during use. In addition, by putting the hook ring on the hook piece, when frame one and frame two rotate to unfold, the hook ring and hook piece are hooked together, realizing the rotation restriction of frame one and frame two, which is simple and convenient to operate.

[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0020] This embodiment mainly describes the anti-tilting structure of a foldable walking machine that is easy to operate and prevents the running board from tilting up, as detailed below: like Figure 1-7 As shown, the anti-tilting structure of the folding treadmill includes a frame 1a and a frame 1b that are arranged adjacently and rotatably connected by a hinge 4. The frame 1a and the frame 1b can rotate to a horizontal position and be distributed left and right or stacked up and down. The front and rear sides of the frame 1a are fixed with hooks 2, and the front and rear sides of the frame 1b are rotatably installed with hook rings 3. The hook rings 3 can hook onto the hooks 2 to achieve a rotational restriction connection between the frame 1a and the frame 1b. When the hook rings 3 hook onto the hooks 2, they can act to abut the ends of the frame 1a and the frame 1b. The hook rings 3 and the hooks 2 generate a pulling force towards the two ends of the frame 1a and the frame 1b that are far away from each other. The pulling force is directed towards the left and right ends.

[0021] Preferably, the rotation axes of frame 1a and frame 1b are distributed front to back and can form an angle with the direction of the tension generated between the hook 3 and the hook 2, and the hook 3 on frame 1b can be set without rotation.

[0022] By hooking the hook ring 3 to the hook piece 2 and generating a pulling force on both ends of the hinged frame 1a and frame 1b, a tension structure is formed, which makes the hinged frame 1a and frame 1b have high impact resistance and stability, effectively preventing the running board 5 from tilting upward due to external forces or other factors, maintaining the stability of the overall structure of the walking machine, and improving the safety of the walking machine during use. Furthermore, by putting the hook ring 3 on the hook piece 2, when the frame 1a and frame 1b rotate to the left and right horizontally unfolded, the hook ring 3 hooks the hook piece 2, thereby restricting the rotation of the frame 1a and frame 1b, which is simple and convenient to operate.

[0023] like Figure 2-7 As shown, each of the frame 1a and frame 2b is provided with a mounting part 1-1. A hinge 4 is fixed on the mounting part 1-1 of the frame 1a and frame 2b to realize the rotational installation between the frame 1a and frame 2b. In this embodiment, the mounting part 1-1 protrudes from the upper end surface of the frame 1a and frame 2b, and each of the frame 1a and frame 2b is fixed with a running plate 5. The running plate 5 is provided with a clearance opening 5-1 to avoid the mounting part 1-1 and the hinge 4.

[0024] A motor 6 and a rotatably mounted axle 7a are installed on the left end of frame 1a. A belt 8 for rotational transmission is connected between the output end of motor 6 and axle 7a. Motor 6 can drive axle 7a to rotate through belt 8. Axle 7b is rotatably mounted on the right end of frame 1b. Running plate 5 is located between axle 7a and axle 7b. Running belt 9 is sleeved on axle 7a and axle 7b. Running belt 9 has a racetrack-shaped closed structure. Running plate 5 is located in running belt 9.

[0025] In this embodiment, to prevent the mounting part 1-1 and the hinge 4 from acting on the running belt 9, the mounting part 1-1 and the hinge 4 are flush with or lower than the upper surface of the running plate 5, and the clearance opening 5-1 on the running plate 5 is located on the front and rear sides of the running belt 9. To ensure the aesthetic appearance of the walking machine, a cover plate 10 is fixed on the front and rear sides of the upper part of the frame 1a and the frame 2b or the running plate 5. The cover plate 10 covers the side of the running plate 5 and the clearance opening 5-1.
