Description

Technical Field

[0001] This application relates to the field of sports and fitness equipment, and in particular to a single-tube folding mechanism for a double-layer shock-absorbing treadmill. Background Technology

[0002] In modern life, treadmills are a common type of fitness equipment, widely used in homes, gyms, and other places. When designing treadmills, in addition to fulfilling their functional requirements, ease of transportation and storage has become an important consideration. Folding treadmills, because they effectively save space when not in use, have become popular among users.

[0003] Existing dual-layer shock-absorbing treadmills typically employ a single-tube folding structure. This structure uses two effective points on the upright to lock it in place: a rotating point at the top for folding and rotating, and a locking point at the bottom to securely hold the upright in place when the treadmill is unfolded. However, to ensure that the force applied at these two points matches the height of the upright, a certain effective distance must exist between these two points.

[0004] In the transportation of treadmills, the effective distance required to lower the upright tube into the packaging box presents numerous challenges. This limited distance necessitates extending the length of the packaging box to accommodate the lowered upright tube. This increased box length not only directly raises packaging material costs but also reduces the number of treadmills that can be loaded into each container during shipping, significantly increasing transportation costs. Furthermore, the larger packaging boxes create inconveniences during warehousing and handling, further increasing the overall product cost and reducing its market competitiveness. Therefore, resolving the issues arising from the upright tube structure during the packaging and transportation of existing single-upright folding treadmills has become a pressing technical challenge. Utility Model Content

[0005] This utility model discloses a single-tube folding mechanism for a double-layer shock-absorbing treadmill, which solves the problem of excessive packaging space occupied by single-tube folding treadmills during packaging and transportation.

[0006] A single-upper tube folding mechanism for a double-layer shock-absorbing treadmill, having a folded state and an unfolded state, includes: a base for mounting the running belt, one end of which has a connecting seat; and a handrail component with an upright tube for support.

[0007] The riser has opposite rotating ends, and a movable hole for hinged connection of the connecting seat is provided on the side near the rotating end. The riser can rotate around the movable hole for folding of the base and the handrail component.

[0008] The movable hole extends along the axial direction of the riser, allowing the riser to slide relative to the connecting seat along the movable hole, which is used to adjust the relative position of the base and the handrail component after folding.

[0009] The end of the movable hole furthest from the rotating end corresponds to the unfolded state, and the end closest to the rotating end corresponds to the folded state.

[0010] In this application, a movable hole is provided at one end of the riser that connects to the connecting seat, and the movable hole has a certain length. This length is set along the axial direction of the riser, so that the riser and the connecting seat form a rotatable and relatively sliding connection structure. This is used to adjust the relative position of the base and the handrail component after the base and handrail component are folded relative to each other, so that the extension length of the rotating end of the riser in the folded state is consistent with that of the base, thus avoiding the problem of excessive packaging space.

[0011] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0012] Optionally, the connecting seat includes a connecting shaft that connects to the movable hole, and a connecting shaft fixing bracket that connects to the base.

[0013] Optionally, the connecting seat is provided with a fixing part and a fixing component detachably connected to the fixing part, and the riser is provided with a through hole for the fixing component to pass through partially, for fixing the base and the handrail component when unfolded.

[0014] Optionally, the riser has a front side and a rear side, and the end of the riser has a fixing part through hole for the fixing part to pass through. The fixing part through hole is located on the pipe wall on the rear side of the riser. In the unfolded state, the end of the fixing part abuts against the pipe wall on the front side of the riser through the fixing part through hole and cooperates with the fixing component to fix the pipe wall on the front side of the riser.

[0015] Optionally, the fixing part is provided open on one side of the end near the rotating end of the riser through the hole.

[0016] Optionally, the height difference between the horizontal height of the connecting shaft's axis and the horizontal height of the base is at least greater than the thickness of the riser wall.

[0017] Optionally, the movable hole is a straight strip-shaped hole and is arranged parallel to the axial direction of the riser.

[0018] The beneficial effects of this application are as follows:

[0019] In this application, a movable hole is provided at one end of the riser that connects to the connecting seat, and the movable hole has a certain length. This length is set along the axial direction of the riser, so that the riser and the connecting seat form a rotatable and relatively sliding connection structure. This is used to adjust the relative position of the base and the handrail component after the base and handrail component are folded relative to each other, so that the extension length of the rotating end of the riser in the folded state is consistent with that of the base, thus avoiding the problem of excessive packaging space.

[0029] 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, and 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.

[0030] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] refer to Figure 1 and Figure 2 In one embodiment of this application, a single-tube folding mechanism for a double-layer shock-absorbing treadmill is disclosed, including a base 1 for setting the running belt and a handrail component 2 connected to the base 1. The base 1 and the handrail component 2 are rotatably connected to form a folded state for storage and an unfolded state for use.

[0033] The handrail component 2 includes a handrail and a display component located on the riser 21. The base 1 has a connecting seat 11 at its front end relative to the direction of movement of the user on the running belt. The riser 21 has a rotating end corresponding to the connecting seat 11 and a movable hole 22 is provided on the side near the rotating end. The movable hole 22 is used to hinge with the connecting seat 11 to fold or unfold to form the folded state and unfolded state.

[0034] Furthermore, the movable hole 22 extends along the axial direction of the riser 21 to form an elongated structure, which allows the riser 21 to slide relative to the connecting seat 11 along the movable hole 22, thereby adjusting the relative position of the base 1 and the handrail component 2 after folding.

[0035] It needs to be explained that the end of the movable hole 22 furthest from the rotating end corresponds to the unfolded state, and the end closer to the rotating end corresponds to the folded state.

[0036] refer to Figure 3 and Figure 4 The connecting base 11 includes a connecting shaft 12 that connects to the movable hole 22, and a connecting shaft fixing bracket 13 connected to the base 1. After the connecting shaft 12 passes through the movable hole 22, its two ends are respectively fixed to the connecting shaft fixing bracket 13.

[0037] To maintain the relative position of the riser 21 and the base 1 in the unfolded state and prevent the riser 21 from rotating during use, a fixing part 14 and a fixing component 15 detachably connected to the fixing part 14 are provided on the connecting seat 11. Correspondingly, the riser 21 is provided with a through hole 24 for the fixing component 15 to pass through partially, for fixing the base 1 and the handrail component 2 when unfolded.

[0038] To strengthen the fixing of the riser 21 by the fixing component 15, the riser 21 has a front side and a rear side. The end of the riser 21 has a fixing part through hole 23 for the fixing part 14 to pass through. The fixing part through hole 23 is located on the pipe wall of the rear side of the riser 21. In the unfolded state, the end of the fixing part 14 abuts against the pipe wall of the front side of the riser 21 through the fixing part through hole 23, and cooperates with the fixing component 15 to fix the pipe wall of the front side of the riser 21.

[0039] Furthermore, the fixing part is provided open on the end side of the hole 23 near the rotating end of the riser 21, so that the fixing part 14 can pass through quickly.

[0040] To ensure that the riser 21 can rotate around the connecting shaft 12 and to avoid interference between the riser 21 and the base 1 during rotation, the height difference between the horizontal height of the axis of the connecting shaft 12 and the horizontal height of the base 1 must be at least greater than the thickness of the riser 21 wall.

[0041] In one embodiment, the movable hole 22 is a straight strip-shaped hole and is arranged parallel to the axial direction of the riser 21 (e.g., Figure 3 and Figure 4 (As shown).

[0042] In another embodiment, the movable hole 22 is a straight strip-shaped hole arranged at an angle (as shown in Figure 5), or the movable hole 22 is arc-shaped (as shown in Figure 5). With this arrangement, the movable hole 22 allows the base 1 to abut against the rear wall of the riser 21 when the riser 21 is in the unfolded state, thus limiting the riser 21 when it is not lifted in the height direction. The riser 21 needs to be lifted to allow for rotation between it and the base 1, creating a rotatable allowance, before it can rotate around the connecting shaft 12.

[0043] It should be noted that in the previous embodiment, the following conditions must be met: 1. In the folded state, there is a height difference between the two ends of the movable hole 22 and the base 1. 2. In the folded state, the height of the end of the movable hole 22 furthest from the rotating end is greater than the height of the other end, and the height of the other end must be greater than the horizontal height of the base 1 to ensure that the riser 1 folds smoothly. 3. In the unfolded state, the maximum horizontal distance from the end of the movable hole 22 furthest from the rotating end to the rear wall of the riser 21 is consistent with the maximum horizontal distance from the movable hole 22 to the base 1.

[0044] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0045] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
