Description

Technical Field

[0001] The utility model relates to the technical field of sports training equipment, in particular to an adjustable sports training running aid. Background Art

[0002] A running block is a track and field running device, mainly used in various large-scale events and daily sports training. It can adjust the athlete's squat starting posture at the start, effectively reducing the time the athlete takes to accelerate in the starting phase. Historically, the invention of the running block is related to the Australian sprinter Sherrill. After observing the running style of kangaroos, he imitated their movements and invented the squat start. This starting method was later widely adopted and eventually evolved into the modern running block. The running block is an indispensable equipment in track and field sports and daily sports training. It helps athletes get in the best condition at the start by providing stable support and proper adjustment functions, thereby achieving better results in competitions or training.

[0003] The development of running blocks has also undergone many improvements. For example, a split structure has emerged, which allows the two pedals to be adjusted independently. By setting a spike structure at the bottom of the pedals to fix them on the runway, athletes can adjust the position of the two pedals according to their own habits, so as to better adapt to their personal starting habits. However, existing adjustable sports training running blocks often only have the ability to adjust the pedals forward and backward. Athletes' feet and legs are of different lengths, and adaptive fine-tuning of the left and right position and inclination angle of the pedals cannot be performed, which affects the use range of the running block and also affects the athletes' starting. Utility Model Content

[0004] In order to make up for the above shortcomings, the present invention provides an adjustable sports training treadmill, which aims to improve the existing adjustable sports training treadmill, which often only has the front and back adjustment of the pedals. Athletes' feet and legs are of different lengths, and the left and right positions and inclination angles of the pedals cannot be adaptively fine-tuned, which affects the use range of the treadmill and also affects the athlete's starting point.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an adjustable sports training treadmill, comprising a fixed seat, a fixed seat groove being provided inside the fixed seat, a bidirectional screw being provided inside the fixed seat, the bidirectional screw being located inside the fixed seat groove, one side of the bidirectional screw passing through one side of the fixed seat and being fixedly connected to a first hand wheel, the outer wall of the bidirectional screw being symmetrically threaded with a first sliding block, one side of the first sliding block being fixedly connected to a connecting seat, the side of the connecting seat away from the first sliding block being fixedly connected to an adjusting plate, an adjusting plate groove being provided inside the adjusting plate, a screw being provided inside the adjusting plate, and the screw being located inside the adjusting plate groove.

[0006] Preferably, the outer wall of the screw rod is threadedly connected to a second sliding block, one side of the second sliding block is fixedly connected to a fixing plate, and the fixing plate is L-shaped.

[0007] Preferably, a groove is provided at the bottom of the fixing plate, and a pedal is rotatably connected to the inside of the groove at the bottom of the fixing plate via a first rotating shaft.

[0008] Preferably, a groove is provided at the bottom of the pedal, and a pedal adjustment block is rotatably connected to the inside of the groove at the bottom of the pedal via a second rotating shaft.

[0009] Preferably, the bottom surface of the fixing plate is evenly provided with adjustment grooves, and the adjustment grooves match the pedal adjustment blocks.

[0010] Preferably, a second hand wheel is rotatably connected to a side of the connecting seat away from the connecting seat, and one end of the second hand wheel passes through a side of the connecting seat and is fixedly connected to a worm.

[0011] Preferably, one end of the screw rod passes through one side of the connecting seat and is fixedly connected to a turbine, and the outer wall of the turbine is meshedly connected to the outer wall of the worm.

[0012] Preferably, a fixing bracket is fixedly connected to a side of the fixing seat away from the bidirectional screw rod.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the present invention, by rotating the first hand wheel, the bidirectional screw rod is driven to rotate, thereby driving the two first sliders to move closer to or away from each other horizontally left and right, thereby driving the connecting seat, the adjustment plate, the fixing plate and the pedal to move closer to or away from each other horizontally left and right, so that the pedal can be adjusted to the appropriate left and right level according to the athlete's own situation, so as to provide the athlete with a good running-up effect.

[0015] 2. In the present invention, by rotating the second hand wheel, the fixed plate and the pedal are driven to move horizontally forward and backward, so that athletes can adjust the front and rear positions of the left and right pedals according to their own situation, thereby improving their running-up effect. By rotating the pedal adjustment block and matching it with the adjustment slot, the inclination angle of the pedal can be adjusted, so that athletes can adjust the inclination angle of the pedal according to their own situation, providing athletes with better running-up effect and comfort, and improving the scope of use of the running aid.
