Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically a track starter for sports training. Background Technology

[0002] Physical training is conducted to enhance soldiers' physical fitness, cultivate courage and resilience, and equip them with practical military skills. It forms the foundation of all training programs and serves to improve the combat effectiveness of the armed forces. Starting blocks are auxiliary equipment used in track and field, primarily for sprint events, to help athletes gain better initial speed at the start.

[0003] Patent CN220989659U discloses a starting device, which includes a main base and foot pedals disposed on both sides of the main base. The bottom of the main base is provided with waterproof protrusions on both sides, and two symmetrically arranged line grooves are provided in the middle of the bottom of the main base. The device has a simple structure. The line grooves at the bottom of the starting device allow the line to pass through, avoiding the line passing through the main base. This not only improves the appearance, but also strengthens the structural strength of the starting device, and allows the bottom of the starting device to be closer to the ground.

[0004] However, the existing device involves fixing the front and rear fixed plates to the training ground and using foot pedals to start the race. In order to maintain the stability and sturdiness of the starting device, the front and rear fixed plates are generally made of metal, which results in a large overall weight of the starting device. Furthermore, due to the presence of asymmetrical foot pedals, it is more difficult to move and carry the starting device conveniently, thus affecting training. Therefore, a track starting device for sports training is proposed to solve the problem that the existing starting devices are too heavy and difficult to move and carry conveniently.

[0014] (III) Beneficial Effects

[0015] 1. This track starter for sports training involves removing the foot pedal and placing it inside the main body of the starter. Raising one side of the main body of the starter, and with the help of the rotating shaft, the rotating arm and rollers rotate out of the rotating groove. Keeping the rotating arm at a 90-degree angle, rotating the knob in the groove drives the limit screw to move towards the rotating arm and press it to limit. The same operation is performed to rotate the two sets of rollers on the other side out of the limit. With the help of the second rotating shaft, the pull plate is rotated out of the main body of the starter, which can then be dragged to move the starter. This solves the problem that existing starters are too heavy and difficult to move and carry conveniently.

[0016] 2. This track starter for sports training adjusts the position of the limit block by adjusting the T-shaped block in the T-slot, so that the connecting block moves to align with the corresponding locking block. Then, the limit bolt is tightened to fix the limit block, and the connecting bolt is tightened again. The connecting bolt is connected to the locking block by cooperating with the connecting screw hole, which improves the stability and firmness of the pedal, that is, improves the stability of this track starter for sports training when in use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-5A track starter for sports training includes a starter body 1, foot pedals 2 at both ends of the starter body 1, a slot 3 on the top of the starter body 1, a locking block 4 inside the slot 3, a limiting hole 5 through one side of the starter body 1, symmetrical rotating grooves 6 inside the starting body 1, a rotating arm 7 inside the rotating groove 6, a roller 8 rotatably connected to one side of the rotating arm 7, the rotating arm 7 being rotatably connected to the inner cavity of the rotating groove 6 by a rotating shaft 9, grooves 15 at both ends of the starter body 1, a limiting screw 10 screwed into the inner wall of the groove 15, a knob 11 inside the groove 15, a pull plate 12 inside the starting body 1, the pull plate 12 being rotatably connected to the inner cavity of the starting body 1 by a second rotating shaft 13, and a stabilizing mechanism 14 on the top of the pull plate 12.

[0025] Furthermore, the locking block 4 is fixedly connected to the foot pedal 2, and the rotating groove 6 penetrates the inner cavity of the starter body 1.

[0026] Furthermore, the limiting screw 10 extends into the inner cavity of the rotating groove 6, and the knob 11 is fixedly connected to the limiting screw 10. The foot pedal 2 is removed and placed into the starting device body 1. One side of the starting device body 1 is raised, and with the cooperation of the rotating shaft 9, the rotating arm 7 and the rollers 8 rotate out of the rotating groove 6. The rotating arm 7 is kept at a 90-degree angle. The knob 11 in the rotating groove 15 drives the limiting screw 10 to move towards the rotating arm 7 and presses it to limit. The same operation is performed to rotate the two sets of rollers 8 on the other side out of the limit. With the cooperation of the second rotating shaft 13, the pull plate 12 is rotated out of the starting device body 1, and the starting device can be dragged to move. This solves the problem that the existing starting devices are too heavy and difficult to move and carry conveniently.

[0027] Furthermore, the stabilizing mechanism 14 includes T-shaped grooves 141 symmetrically opened on the top of the pull plate 12, a T-shaped block 142 is slidably arranged in the inner cavity of the T-shaped groove 141, and a limiting block 143 is provided on the top of the pull plate 12, with the limiting block 143 fixedly connected to the T-shaped block 142.

[0028] Furthermore, a connecting block 144 is fixedly connected to one end of the limiting block 143. The shape of the connecting block 144 is the same as that of the locking block 4. A limiting bolt 145 is screwed onto the top of the limiting block 143.

[0029] Furthermore, the limiting bolt 145 passes through the limiting block 143, the T-block 142 and into the inner cavity of the T-slot 141. One end of the locking block 4 is provided with a connecting screw hole 146, and one end of the connecting block 144 is connected with a connecting bolt 147 that matches the connecting screw hole 146. After using this starter and adjusting the position of the pedal 2, the position of the limiting block 143 is adjusted by the T-block 142 in the T-slot 141, so that the connecting block 144 moves to align with the corresponding locking block 4. Then, the limiting bolt 145 is tightened to fix the limiting block 143, and the connecting bolt 147 is tightened. The connecting block 144 is connected to the locking block 4 by the connecting screw hole 146, which improves the stability and firmness of the pedal 2, that is, improves the stability of this track starter for sports training.

[0030] Working principle: When using this sports training track starter, the starter body 1 is fixed in the required position by using the limiting hole 5 and screws and other fixing connectors. Then, the foot pedals 2 are set at the appropriate positions at both ends of the starter body 1 by the cooperation of the locking blocks 4 in the slot 3, which facilitates the use of this sports training track starter. After using this starter, the restriction of the starter body 1 is released. The two foot pedals 2 are put into the inner cavity of the starter body 1 and the locking blocks 4 are locked into the slot 3. Then, one side of the starter body 1 is raised. With the help of the rotating shaft 9, the rotating arm 7 and the rollers 8 are rotated out of the rotating groove 6. The rotating arm 7 is kept at a 90-degree angle. The knob 11 in the rotating groove 15 drives the limiting screw 10 to move towards the rotating arm 7 and press it to limit. The same operation is performed to rotate the two sets of rollers 8 on the other side out of the limit. With the help of the second rotating shaft 13, the pull plate 12 is rotated out of the starter body 1, and the starter can be dragged to move. This solves the problem that the existing starters are too heavy and difficult to move and carry.
