Description

Technical Field

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

[0002] As a popular fitness equipment, convenience is one of the most important features of treadmills. However, the existing treadmill incline adjustment structure is generally quite complex and has high production costs. In particular, some motor-driven adjustment structures are quite bulky and inconvenient to store and transport. Utility Model Content

[0003] In view of the defects of existing treadmill incline adjustment structures, the technical problem to be solved by this utility model is to provide a treadmill incline adjustment structure that is simple in structure, low in production cost, small in size, light in weight, and convenient for storage and transportation.

[0004] To achieve the above objectives, according to one aspect of the present invention, the present invention is implemented through the following technical measures: a treadmill incline adjustment structure, comprising a fixed block, a support rod, and a positioning pin, wherein the fixed block is fixedly connected to both sides of the treadmill support, the fixed block is provided with a plurality of positioning holes, the positioning pin is inserted into the positioning holes, the support rod is disposed on both sides of the treadmill and is respectively hinged to the fixed block, and one side of the support rod abuts against the positioning pin during use.

[0005] Furthermore, connecting rods are fixedly connected between the support rods.

[0006] Furthermore, the lower end of the support rod is provided with a round tube rubber sleeve.

[0007] Furthermore, the support rod is provided with a storage hole.

[0008] Compared with the prior art, the advantages of this utility model are as follows: This treadmill incline adjustment structure allows for adjustment of the treadmill incline by simply pulling out the positioning pin and inserting it into the positioning hole corresponding to the target angle, and rotating the support rod so that one side of it abuts against the positioning pin. The structure is simple and easy to operate. The adjustment structure is small in size and light in weight, and has good flatness when stored, making it easier to package and transport. The connecting rod is fixedly connected to the support rods on the left and right sides of the treadmill, allowing the support rods on both sides to be adjusted synchronously and providing better stability. The lower end of the support rod is equipped with a round tube rubber sleeve, which can prevent the support rod from scratching the ground and increase the overall stability (increasing friction to prevent the support rod from sliding on the ground during exercise).

[0013] 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.

[0014] 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.

[0015] Please refer to Figure 1 , Figure 2 This embodiment provides a treadmill incline adjustment structure, including a fixing block 1, a support rod 2, a positioning pin 3, and a connecting rod 4. An incline adjustment structure is provided on each of the left and right sides of the treadmill. The fixing block 1 is fixedly connected to the treadmill support 5 (in this embodiment, it is fixed by welding). The fixing block 1 has a connecting hole and several positioning holes 6. The upper end of the support rod 2 has a connecting hole, and the support rod 2 and the fixing block 1 are hinged together by a connecting pin 9 inserted into the connecting hole. The support rod 2 also has a storage hole 7, and the lower end of the support rod 2 has a round tube rubber sleeve 8. The connecting rod 4 is fixedly connected to the support rods 2 on the left and right sides of the treadmill.

[0016] This embodiment provides a treadmill incline adjustment structure. When incline adjustment is needed, lift the treadmill platform or tilt the treadmill to the side (operation is safer in the tilted position), pull out the positioning pin 3, insert the positioning pin 3 into the positioning hole 6 corresponding to the required angle position (the three positioning holes 6 shown in the attached figure correspond to inclines of 0.5°, 2.5°, and 4.5°, respectively), rotate the support rod 2 so that one side rests against the positioning pin 3, and reset the treadmill to complete the adjustment; when storing, tilt the treadmill to the side, pull out the positioning pin 3, move the support rod 2 until the storage hole 7 and the positioning hole 6 are aligned, insert the positioning pin 3 into the storage hole 7 and the positioning hole 6 to complete the storage and fixation of the support rod 2.

[0017] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various changes and modifications can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
