[0033] The utility model provides a starting block which is convenient to adjust. To make the purpose, technical solution and effect of the utility model clearer and more definite, the following takes examples with reference to the drawings and further elaborates on the utility model in detail.

[0034] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "up and down, left and right" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, and should not be construed as a limitation to the present utility model. In addition, terms such as "installation" and "connection" should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0035] Please refer to Figures 1 to 8 , the utility model provides a starting block which is convenient to adjust, which includes a base main body 1, a footrest 2, a fixed toothed plate 3, an adjusting toothed plate 4, an adjusting handle 5, a fixed shaft 6, a locking gear 7, an adjusting gear 8, a footrest 9 and a locking assembly. The adjusting toothed plate 4 is fixed on the outer side of the footrest 2, and the fixed toothed plate 3 meshing with the adjusting toothed plate 4 is fixed on the base main body 1. Specifically, the fixed toothed plate 3 is arranged on the inner side of the base main body 1. The adjusting handle 5 is connected to the adjusting toothed plate 4 so that the user can adjust the position of the footrest 2 by operating the handle.

[0036] A fixed shaft 6 is horizontally arranged inside the footrest 2, and a locking gear 7 and an adjusting gear 8 which are meshed with each other are arranged on the fixed shaft 6. The locking gear 7 is configured with a locking assembly for switching the locking state, and the adjusting gear 8 is connected to the footrest 9. The footrest 9 is rotatably connected to the front end of the footrest 2, providing an adjustable and stable support point for the athlete.

[0037] The locking assembly includes a return spring (not shown in the figure), an unlocking wedge 14 and an unlocking groove 15. One side of the locking gear 7 is held by the return spring, and the adjusting gear 8 meshes with the other side of the locking gear 7. The unlocking groove 15 is opened on the locking gear 7, and the unlocking wedge 14 is arranged above the unlocking groove 15 near the return spring side. A notch is designed at the opening of the unlocking groove 15, so that the unlocking wedge 14 can be accurately positioned and prevent accidental movement, and at the same time, it is convenient for the locking wedge to smoothly enter the unlocking groove 15 to form a lock.

[0038] To further improve the convenience of operation, the pedal device further includes a control handle 16, a driving block 17 and a driving groove 18. The fixed end of the control handle 16 is rotatably arranged on the fixed base 19. The driving block 17 is fixed in the middle of the control handle 16, and the top of the unlocking wedge 14 is provided with a driving groove 18, and the driving block 17 can move in the driving groove 18. Specifically, the pedal 2 further includes a fixed base 19. The footrest plate 9 is rotatably connected to the front end of the fixed base 19. A fixed shaft 6 is horizontally arranged in the fixed base 19, allowing the athlete to adjust to the most comfortable angle according to needs, enhancing the applicability and comfort of the starting block. The pedal devices 2 are arranged on both sides of the base body 1 to provide symmetric support and adjustment functions.

[0039] The specific working principle is as follows. When it is necessary to adjust the position of the footrest plate 9, the reset spring is compressed or released by operating the unlocking component, so as to allow or prohibit the rotation of the locking gear 7. Specifically, when the adjustment control handle 16 is pressed downward, the unlocking wedge 14 pushes the locking gear 7 to move leftward through the unlocking groove 15, releasing the meshing state between the locking gear 7 and the adjusting gear 8, so as to adjust the inclination angle of the arm footrest plate 9. In the unlocked state, by rotating the adjusting gear 8 to rotate along the fixed shaft 6, the footrest plate 9 is driven to be adjusted to a suitable position, that is, the movement of the adjusting gear 8 is converted into the change of the angle of the footrest plate 9. In the locked state, the locking gear 7 is pushed to reset by the reset spring to perform locking.

[0040] In this embodiment, it further includes a housing 10 and a rotating shaft. The housing 10 is fixed on the outer wall of the pedal 2, and a rotating shaft is fixed in the housing 10. The adjusting handle 5 is rotatably installed on the rotating shaft, providing a stable operation platform for smooth rotation for users, improving the service life and user experience. In addition, a connecting arm 11 is provided on the adjusting tooth plate 4, and an arc-shaped groove 12 is provided on the adjusting handle 5. The connecting arm 11 can rotate in the arc-shaped groove 12, simplifying the biting and loosening operations of the fixed tooth plate 3 and the adjusting tooth plate 4, and providing better mechanical advantages and ergonomic experience.

[0041] The starting block that is convenient to adjust is also provided with a detachable connecting block 13. Specifically, the connecting block 13 is fixedly connected to the housing 10 by bolts. The connecting block 13 is arranged in the housing 10 and is provided with a through hole, and the rotating shaft is located in this through hole, facilitating the maintenance and replacement of components.

[0042] Please refer to Figure 8 , in another feasible embodiment, the fixed tooth plate 3 is arranged on the outside of the base body 1. In addition, it further includes a one-way handle provided for conveniently extracting the starting block. The one-way handle is relatively small in volume and is arranged on the base body 1 near the center of the starting block, which can reduce the risk of pinching hands.

[0043] In summary, for the easily adjustable starting block of the present utility model, the adjusting toothed plate 4 installed on the outside of the footrest 2 meshes with the fixed toothed plate 3 on the base body 1. Athletes or coaches can achieve fine adjustment of the front and rear positions of the footrest 2 by operating the adjusting handle 5 connected to the adjusting toothed plate 4, making the adjustment process smooth and highly precise. Inside the footrest 2, a locking gear 7 and an adjusting gear 8 that mesh with each other are penetrated on a horizontally arranged fixed shaft 6. A locking assembly is arranged on the locking gear 7 to control the locking and unlocking of the locking gear 7, facilitating flexible rotation and fixing the angle of the footrest 9 driven by the adjusting gear 8, adapting to different personal starting techniques and leg strengths, quickly adjusting to the best starting posture, and helping to improve the starting efficiency and reduce the muscle burden during starting. Therefore, the present utility model effectively overcomes various drawbacks in the prior art and has high industrial utilization value.

[0044] It can be understood that for those of ordinary skill in the art, equivalent replacements or changes can be made according to the technical solution of the present utility model and its inventive concept, and all such changes or replacements should fall within the protection scope of the present utility model.
