Description

Technical Field

[0001] The utility model relates to the technical field of starting blocks, in particular to an adjustable sports training starting block. Background Art

[0002] A starting block is a piece of equipment used in track and field competitions, primarily in sprint events. It provides athletes with a starting force by utilizing the principle of force interaction. When an athlete steps on the starting block, the block applies a force, which is then transferred to the athlete's feet in response, helping them get started.

[0003] The existing starting blocks use bolts to adjust the angle of the pedals. However, it is difficult to find the corresponding tools on the field and during sports training. As a result, the angle of the pedals is often adjusted by hand screws. However, the hand screws are not stable and it is difficult to turn the screws by hand during subsequent disassembly, making adjustment more troublesome. Therefore, an adjustable sports training starting block is proposed to solve the above problem. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an adjustable sports training treadmill, including a fixing frame, fixed grooves are provided on both sides of the fixing frame, connecting plates are clamped inside the fixing grooves, a fixing seat is fixed on the surface of the connecting plate, the fixing seat is rotatably connected to a rotating rod inside, the surface of the rotating rod is rotatably connected to a pedal plate, the inner surface of the pedal plate is rotatably connected to an upper rotating plate, the lower end of the upper rotating plate is rotatably connected to a lower rotating plate, the other end of the lower rotating plate relative to the upper rotating plate is rotatably connected to the fixing frame, the surfaces of the lower rotating plate and the upper rotating plate are rotatably connected to a locking rod, the surface of the fixing seat is provided with a locking hole, and the locking rod and the locking hole are plugged into each other.

[0006] Preferably, a limit frame is fixed on the surface of the fixing seat, and a sliding rod is slidably connected to the interior of the limit frame.

[0007] Preferably, a stabilizing plate is fixed to the lower end of the slide rod, and a locking groove is provided on the surface of the stabilizing plate.

[0008] Preferably, the locking rod and the locking groove are engaged with each other, and the sliding rod and the limiting frame are arranged above the stabilizing plate.

[0009] Preferably, a movable groove is provided on the surface of the fixing seat, and the movable groove and the locking hole are symmetrically arranged relative to the fixing seat.

[0010] Preferably, the pedal surface is provided with a fitting protrusion, and the curvature of the pedal surface is consistent with the curvature of the foot force.

[0011] Compared with the related art, the adjustable sports training running aid provided by the present invention has the following beneficial effects:

[0012] The utility model fixes the position of the locking rod through the locking hole and the stabilizing plate to stabilize the angle of the pedal board. The movement of the locking rod adjusts the angle of the pedal board. The angle of the pedal board can be changed according to the needs of the user to adapt to people of different body shapes and physiques. At the same time, it is more convenient to adjust and avoids the trouble caused by tightening screws. BRIEF DESCRIPTION OF THE DRAWINGS
