DETAILED DESCRIPTION

[0029] The principles and features of the present application are described below in conjunction with the accompanying drawings, and the examples are only used to explain the present application and are not used to limit the scope of the present application. In the following paragraphs, the present application is described in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present application will be more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and use non-precise proportions, only to facilitate and clarify the purpose of assisting the description of the embodiments of the present application.

[0030] As Figures 1-3As shown, this embodiment provides a leg ligament relaxer for running, including a seat frame 1 and two leg supports 2. The two leg supports 2 are arranged in front of the seat frame 1 in a front-back direction, and the two leg supports 2 are spaced apart in a left-right direction on the front side of the seat frame 1. The rear end of each leg support 2 is swung to the lower front end of the seat frame 1, so that the athlete can sit on the seat frame, with both legs resting on the two leg supports respectively, and then perform leg opening and closing operations to stretch and relax the ligaments of the legs.

[0031] like Figures 1-3 As shown, the seat frame 1 in the above technical solution includes a seat plate 11 and a support frame 12. The seat plate 11 is horizontally arranged on the upper end of the support frame 12. The rear end of the leg rest 2 is swivelly connected to the lower front end of the seat plate 11, so that the entire seat frame is similar to a chair for athletes to sit on, and also allows the two leg rests to be swivelly installed. The support frame 12 is a U-shaped frame with the groove facing forward. The lower end of the support frame 12 is provided with an anti-slip pad 13 (which can be a layer of rubber pad, similar to the material of a tire). Its structure is simple and has good stability, and it can also prevent the seat frame from slipping on the ground. The upper end of the seat plate 11 is provided with a flexible pad 14 (which can be padded like a sofa, that is, the upper part of the seat plate is wrapped with leather, and sponge material is filled between the leather and the seat plate), so that athletes are comfortable when sitting on the upper part of the seat plate.

[0032] like Figures 1-3 As shown, the leg support 2 in the above technical solution includes a swing arm 21 and a leg support plate 22. Both the swing arm 21 and the leg support plate 22 are horizontally arranged in the front-back direction, and the rear end of the leg support plate 22 is located above the front end of the swing arm 21. The lower rear end of the leg support plate 22 is connected to the upper front end of the swing arm 21 through a connecting block 23. The rear end of the swing arm 21 is connected to the lower front end of the seat frame 1 by left-right swinging. Its structure is simple, and there is a height difference between the leg support plate and the swing arm, which makes the athlete's legs more comfortable to rest on the leg support plate.

[0033] In the above technical solution, both sides of the leg support plate 22 are provided with a U-shaped surrounding plate 24 protruding upwards. The surrounding plates 24 on both sides of the leg support plate 22 are used to prevent the legs from falling off the leg support plate 22. In this way, the legs can be limited by the surrounding plates when they are placed on the leg support plate, so as to prevent the legs from falling off the leg support plate.

[0034] like Figures 2-4As shown, the above technical solution also includes a driving component 3. A worm gear 41 is coaxially fixed at the rear end of the leg support 2 and the rotatable connection of the seat plate 11. A worm 42 located behind the two worm gears 41 is horizontally rotatable at the lower rear end of the seat plate 11 in the left-right direction. The worm 42 has worm segments 421 with opposite spirals at both ends, and the two worm segments 421 correspond one-to-one with the two worm gears 41. Each worm gear 41 meshes with the corresponding worm segment 421. The driving component 3 is mounted on the seat frame 1, and the driving end of the driving component 3 is connected to one end of the worm 42. The driving component 3 rotates clockwise to drive the two leg supports 2 to swing away from each other, or rotates counterclockwise to drive the two leg supports 2 to swing closer to each other. This allows the two leg supports to swing closer or further apart under the drive of the driving component to stretch the ligaments of the legs.

[0035] The driving component 3 in the above technical solution is a servo motor, which has a simple structure, a high degree of automation, and controllable speed; or as... Figures 2-4 As shown, the driving component 3 is a crank handle, and the driving component 3 is connected to one end of the worm gear 42, so that the worm gear can be driven to rotate manually. Specifically, when the driving component is a crank handle, it includes a rotating shaft 31, a rocker arm 32, and a linkage rod 33. The rotating shaft 31 is vertically arranged, and the lower end of the rotating shaft 31 is perpendicular to the worm gear 42 and is connected to it through a steering component 5. The linkage rod 33 is horizontally arranged, and one end is connected to the upper end of the rotating shaft 31. The rocker arm 32 is vertically arranged above the seat plate 11, and the lower end of the rocker arm 32 is connected to the other end of the linkage rod 33. Its structure is simple, so that the athlete can manually drive the two leg rests to swing while sitting on the seat frame.

[0036] like Figure 4 As shown, the steering component 5 includes a housing 51 and two bevel gears 52. The housing 51 is located on one side of the seat frame, and the lower end of the rotating shaft 31 and the corresponding end of the worm gear 42 are both inserted into the housing (the rotating shaft 31 is rotatably connected to the housing 51, and the worm gear 42 is rotatably connected to the housing). The bevel gears are coaxially fixedly mounted on one end of the rotating shaft and the worm gear 42 located inside the housing, and the two bevel gears mesh with each other. When the athlete sits on the seat, he can rotate the drive component to drive the two leg rests to swing synchronously. In this embodiment, the housing and the seat frame can be integrally formed.

[0037] In this embodiment, the rotating shaft 31, rocker arm 32, and linkage rod 33 are connected in a horizontal "Z" shape.

[0038] In the embodiment, the two leg rests are rotated to be opened, and then rotated to be close to each other (the rotation to be straight forward can be considered as close to each other), which can be considered as a cycle action, and the maximum angle of the two leg rests being rotated to be opened can be 60°, and the rotation speed of the two leg rests in the embodiment can be 10-30 cycle actions per minute.

[0039] The above is only a preferred embodiment of the present application, and does not limit the present application in any form; any ordinary technical personnel in the industry can smoothly implement the present application according to the above description and the drawings; however, any equivalent changes, modifications and evolution made by the technical personnel familiar with the profession within the scope of the technical scheme of the present application, using the above disclosed technical content, are equivalent embodiments of the present application; at the same time, any equivalent changes, modifications and evolution of the above embodiments according to the essential technology of the present application are still within the protection scope of the technical scheme of the present application.
