Description

Technical Field

[0001] The present application relates to the technical field of fitness equipment, and in particular to an angle adjustment structure and fitness equipment thereof. Background Art

[0002] In order to adjust the angle of the armrests, the existing foldable treadmills or walking machines and other fitness equipment usually have an angle adjustment structure at the connection between the armrests and the base. The common angle adjustment structure is as follows: Figure 1 The illustrated tooth plate and sleeve combination utilizes a limit pin on the sleeve and a limit block on the tooth plate to limit the armrest's swing angle. Separating the tooth plate and sleeve unlocks the armrest, allowing adjustment of the armrest's swing angle. Once adjustment is complete, reengaging the teeth of the tooth plate and sleeve locks the armrest. While this structure is simple, it's relatively difficult to manufacture, requiring multiple steps like turning, grinding, and drilling, resulting in high costs.

[0003] Therefore, there is an urgent need for an angle adjustment structure and fitness equipment thereof that can significantly reduce costs and improve processing efficiency to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this application is to provide an angle adjustment structure and fitness equipment thereof to address the above-mentioned problems existing in the prior art.

[0005] In order to achieve the above application objectives, the present application adopts the following technical solutions: an angle adjustment structure includes:

[0006] The first rotating disk has a through hole at its center, a circle of evenly arranged tooth-shaped protrusions on its front and rear end surfaces, and a rotation limit baffle in the circumferential direction of the first rotating disk;

[0007] The second rotating disk has a through hole at its center and a circle of evenly arranged tooth-shaped protrusions on its front and rear end surfaces. A limit block is provided in the circumferential direction of the second rotating disk to cooperate with the rotation limit baffle. The rotation angle stroke of the first rotating disk is limited by the two limit blocks.

[0008] A rotating shaft is rotatably connected to the first rotating disk and the second rotating disk, and the first rotating disk can move back and forth along the length direction of the rotating shaft;

[0009] The first rotating disk and the second rotating disk are both formed by an integral molding process or a sheet metal molding process; the first rotating disk and the second rotating disk can rotate relative to each other, and the first rotating disk rotates coaxially with the armrest of the fitness equipment.

[0010] Furthermore, it also includes a connecting disk, which is fixedly connected to the second rotating disk, and the connecting disk is fixedly connected to the rotating shaft or the base frame of the fitness equipment.

[0011] Furthermore, the connecting plate is provided with connecting pieces corresponding one to one with the limiting blocks, and can be fixedly connected to the limiting blocks by welding.

[0012] Furthermore, the first rotating disk and the second rotating disk are made of carbon steel, stainless steel, galvanized sheet or titanium alloy.

[0013] Furthermore, the tooth-shaped protrusions are in a wavy line shape or a broken line shape.

[0014] Furthermore, when the rotation limit baffle abuts against the limit block, the rotation limit baffle can abut against the connecting piece at the same time.

[0015] Furthermore, the material thickness of the first rotating disk and the second rotating disk is 2-4 mm.

[0016] Furthermore, the first rotating disk and the second rotating disk are both formed of sheet metal.

[0017] A fitness equipment is provided with the above-mentioned angle adjustment structure, wherein the armrest of the fitness equipment is coaxially rotatably connected with the first rotating disk of the angle adjustment structure.

[0018] Furthermore, the fitness equipment is a walking machine or a treadmill.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. Simplified structure reduces manufacturing costs: The angle adjustment structure proposed in this application adopts a coordinated design of a first rotating disk and a second rotating disk, and effectively adjusts and locks the armrest angle through a simple tooth-shaped protrusion and a limiting mechanism. Compared with the traditional tooth plate and tooth sleeve structure, the structure in this application is simpler, reducing the number of parts, especially the absence of additional limit pins (because limit pins require additional processing and production, while the rotating limit baffle of this application is integrated with the first rotating disk and does not require additional processing and production), reducing manufacturing difficulty and cost. At the same time, this tooth-shaped protrusion structure has sufficient strength and is suitable for long-term use.

[0021] 2. Improve processing efficiency: The first rotating disk and the second rotating disk can be processed by one-piece molding or sheet metal forming technology. These two processing methods not only improve production efficiency, but also ensure the consistency and quality of the products.

[0022] 3. Convenient Installation and Maintenance: The design of the connecting plate not only facilitates the secure connection between the second rotating plate and the rotating shaft or base frame, but also simplifies the installation process. In addition, the connecting plate and the limit block on the connecting plate are fixed by welding, further strengthening the stability of the connection and facilitating subsequent maintenance and replacement.

[0023] 4. Diverse material selection: The first rotating disk and the second rotating disk can be made of a variety of materials (such as carbon steel, stainless steel, galvanized sheet or titanium alloy), which not only meets the needs of different usage environments, but also provides more flexible cost control options.

[0024] 5. Applicable to a variety of fitness equipment: This angle adjustment structure can be applied not only to treadmills, but also to other types of fitness equipment such as walking machines, increasing its scope of application and market potential.

[0025] In summary, the angle adjustment structure and fitness equipment provided by this application overcome the shortcomings of the existing technology and significantly improve the product's cost-effectiveness and user experience. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting this application.

[0033] Example 1

[0034] like Figure 2-3 As shown, the angle adjustment structure includes:

[0035] The first rotating disk 1 has a through hole at its center and a circle of evenly spaced tooth-shaped protrusions 11 on its front and rear end surfaces. A rotation limiting baffle 12 is provided in the circumferential direction of the first rotating disk 1.

[0036] In this embodiment, the basic nature of the first rotating disk 1 and the second rotating disk 2 is annular, and a circle of tooth-shaped protrusions 11 is formed by sheet metal processing or stamping, which looks like a wavy line or a broken line when viewed from the side. The rotation limit baffle 12 of the first rotating disk 1 is integrated with the first rotating disk 1 and is processed at the same time during its sheet metal forming or stamping. Therefore, no additional processing technology is required, the limit pin structure of the existing technology is eliminated, and the processing cost and parts cost are significantly reduced.

[0037] The second rotating disk 2 is provided with a through hole at the center, and a circle of evenly arranged tooth-shaped protrusions 11 are also provided on the front and rear end surfaces. A limit block 21 is provided in the circumferential direction of the second rotating disk 2 to cooperate with the rotation limit baffle 12. The rotation angle stroke limit of the first rotating disk 1 is achieved by the two limit blocks 21; when the rotation limit baffle 12 abuts against the limit block 21, the rotation limit baffle 12 can simultaneously abut against the connecting piece 31, that is, the length of the bending section of the rotation limit baffle 12 must be long enough.

[0038] In this embodiment, the second rotating disk 2 is processed in the same manner as the first rotating disk 1 and will not be described in detail. Preferably, the material thickness of the first rotating disk 1 and the second rotating disk 2 is 2-4 mm, more preferably, 3 mm pickled plate or hot rolled plate is selected.

[0039] The connecting disk 3 is fixedly connected to the second rotating disk 2 through the connecting disk 3, and the connecting disk 3 is fixedly connected to the rotating shaft 5 or the base frame 41 of the fitness equipment 4. Preferably, the connecting disk 3 is welded to the base frame 41 and the second rotating disk 2, and the rotating shaft 5 is welded to the first rotating disk 1 and the armrest 42, so that the first rotating disk 1 and the second rotating disk 2 can rotate relative to each other;

[0040] In this embodiment, the connecting plate 3 is provided with a connecting piece 31 corresponding to the limit block 21, which can be fixedly connected to the limit block 21 by welding. Of course, the part of the toothed protrusion 11 of the second rotating disk 2 that contacts the connecting plate 3 can also be welded to further reinforce it.

[0041] Preferably, the first rotating disk 1, the second rotating disk 2 and the connecting disk 3 are made of carbon steel or stainless steel or galvanized plate or titanium alloy, which can be determined according to the positioning of the actual product. Carbon steel is generally preferred, such as the 3mm pickled plate or hot-rolled steel plate commonly used in sheet metal forming.

[0042] The rotating shaft 5 is rotatably connected to the first rotating disk 1 and the second rotating disk 2, respectively, and the first rotating disk 1 can move back and forth along the length direction of the rotating shaft 5;

[0043] Among them, the first rotating disk 1 and the second rotating disk 2 are both processed by an integrated molding process or a sheet metal molding process; the first rotating disk 1 and the second rotating disk 2 can rotate relative to each other, and the first rotating disk 1 rotates coaxially with the armrest 42 of the fitness equipment 4.

[0045] Based on embodiment 1, a fitness device 4, such as Figure 4 As shown, the angle adjustment structure of embodiment 1 is provided, and the armrest 42 of the fitness equipment 4 is coaxially rotatably connected with the first rotating disk 1 of the angle adjustment structure, which can realize the locking and loosening rotation and rotation limitation of the armrest 42.

[0046] The fitness equipment 4 is a walking machine or a treadmill.

[0047] The parts not described in detail in this application are prior art, so this application does not describe them in detail.

[0048] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0049] Although this document frequently uses terms such as the first rotating disk 1, the second rotating disk 2, the connecting disk 3, the fitness device 4, the rotating shaft 5, the toothed protrusion 11, the rotation limit baffle 12, the limit block 21, the connecting piece 31, the base frame 41, and the armrest 42, the use of other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of this application; interpreting them as any additional limitations is contrary to the spirit of this application.

[0050] This application is not limited to the above-mentioned optimal implementation method. Anyone can derive various other forms of products based on the inspiration of this application.
