Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to an easily adjustable starting block for sports. Background Technology

[0002] Starting blocks are track and field equipment invented by Sherrill in 1896 and originated in Australia. They are mainly used in sprint events in track and field stadiums to help athletes get off to a quick start. They usually consist of starting frames, starting lines, starting blocks, etc. Modern starting blocks are mostly electronic starting blocks, which have functions such as monitoring athletes' reaction time at the start. They can help referees determine whether there is a false start, greatly improving the fairness and efficiency of the competition. They can also provide athletes with more complete data on their starting status.

[0003] Existing technologies, such as the utility model with publication number CN221788146U, relate to the field of sports equipment, specifically an easily adjustable starting sprinter. It includes a base, a connecting plate fixedly connected to the side of the base, and a first electric push rod and a second electric push rod respectively disposed on the top two sides of the connecting plate. A first support seat is fixedly connected to the output end of the first electric push rod, and a first foot pedal assembly is disposed on the top of the first support seat. A second support seat is fixedly connected to the output end of the second electric push rod, and a second foot pedal assembly is disposed on the top of the second support seat. A first magnetic ring is disposed on the side of the first support seat, and a second magnetic ring is disposed on the side of the second support seat. This utility model uses the first and second electric push rods to move the first and second support seats according to actual conditions, which in turn moves the first and second magnetic rings on an electromagnetic rod. After the position is determined, the electromagnetic rod is energized, thereby fixing the first and second support seats in place.

[0004] However, in the field of sports starting blocks, most starting blocks currently rely on electric means to adjust the distance between the toe plates. But after long-term use, athletes exert tremendous force at the moment of starting, and the powerful impact force is transmitted to the electric equipment, which can easily damage the delicate internal components such as motors, gears and circuits. Frequent and powerful impacts may cause malfunctions, making it difficult to drive the adjustment device normally, which greatly reduces the reliability and service life of the starting block. Utility Model Content

[0005] The purpose of this invention is to address the problem in the field of sports starting blocks where most current starting blocks rely on electric adjustment for the toe plate distance. However, after prolonged use, the athlete's rapid and powerful burst of force at the start can transmit this force to the electric device, easily damaging delicate internal components such as motors, gears, and wiring. Frequent and forceful impacts can also cause malfunctions, making it difficult to properly drive the adjustment device and greatly reducing the reliability and lifespan of the starting block. Therefore, this invention proposes an easily adjustable sports starting block.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an easily adjustable sports starting device, comprising a starting frame and an adjustment device. A base plate is fixedly connected to one side of the starting frame, and toe plates are slidably connected to both sides of the starting frame. The adjustment device is disposed on the surface of the starting frame and includes a strip sleeve fixedly connected to the surface of the starting frame. A slider is fixedly connected to one side of the toe plates. A groove is provided on the side of the starting frame near the slider, and the slider is slidably connected to the starting frame. A fixing rod is fixedly connected to the upper surface of the slider, and a locking plate is rotatably connected to one end of the fixing rod. By setting the adjustment device, when the user exerts force with their legs to start running, the slider bears the main pressure, effectively reducing the stress on the telescopic rod. This greatly reduces the risk of damage to the cylinder and telescopic rod due to excessive starting impact, extends the service life of the electric equipment, reduces the frequency of equipment maintenance and replacement, and ensures the stability and reliability of the starting device's adjustment function.

[0007] Preferably, a cylinder is fixedly connected to one side of the starting frame, and a telescopic rod is fixedly installed on the driving end of the cylinder. By setting the telescopic rod, the thrust generated by the cylinder is converted into linear motion under the drive of the cylinder, thereby pushing the toe plate to slide along the starting frame, so as to achieve precise adjustment of the distance of the toe plate and meet the personalized needs of different athletes for starting posture.

[0008] Preferably, the end of the telescopic rod away from the cylinder passes through the starting frame and is fixedly connected to the toe plate. There are two cylinders, which are arranged symmetrically.

[0009] Preferably, the surface of the strip sleeve is provided with an arc-shaped groove, and there are multiple arc-shaped grooves arranged in a linear array along the strip sleeve, and the clamping plate engages with the arc-shaped groove.

[0010] Preferably, a stabilizing component is provided on one side of the base plate. The stabilizing component includes a restraining rod, which is fixedly connected to the starting frame. A knob is rotatably connected to the surface of the restraining rod, and a pressure plate is fixedly connected to the surface of the knob. By setting up the stabilizing component, a strong grip is provided at the moment the athlete exerts force to start running. This allows the starting frame to be firmly fixed to the ground, greatly reducing the problem of the starting frame deviating due to the athlete's force exertion, and ensuring that the athlete can obtain stable and effective support at the start.

[0011] Preferably, the lower surface of the pressure plate is provided with a large number of conical teeth, and a circular plate is fixedly connected to the surface of the restraint rod. By setting the pressure plate, it can fit tightly with the ground under the elastic force generated by the torsion spring. This fitting action can effectively increase the friction between the pressure plate and the ground, and the conical teeth at the bottom of the pressure plate further enhance its contact effect with the ground, gripping the ground like a claw.

[0012] Preferably, a torsion spring is fitted on the surface of the restraint rod. The two ends of the torsion spring are fixedly connected to the circular plate and the knob, respectively. By setting the torsion spring, when the starting frame is placed on the ground, the elastic force generated by the torsion spring causes the knob to rotate, which in turn drives the pressure plate to move towards the ground and fit tightly against the ground. This continuous squeezing force can ensure that the pressure plate always keeps in contact with the ground and enhance the friction between the starting frame and the ground.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting an adjustment device, during use, the rotating plate disengages from the arc-shaped groove, and then the cylinder is activated. The cylinder drives the telescopic rod to press the toe plate along the starting frame. When the toe plate reaches a suitable distance, the rotating plate abuts against the arc-shaped groove to fix the slider. When the user exerts force with their legs, the slider bears the pressure to reduce the force on the telescopic rod. By setting the adjustment device, when the user exerts force with their legs to start running, the slider bears the main pressure, effectively reducing the force on the telescopic rod. This greatly reduces the risk of damage to the cylinder and telescopic rod due to excessive starting impact, extends the service life of the electric equipment, reduces the frequency of equipment maintenance and replacement, and ensures the stability and reliability of the starting device adjustment function.

[0014] 2. In this utility model, by setting a stabilizing component, when the starting frame is placed on the ground, the torsion spring generates elastic force to squeeze the knob to rotate. The knob drives the pressure plate to fit tightly against the ground, and at the same time, the conical teeth at the bottom of the pressure plate grip the ground firmly, providing grip when the user exerts force, reducing the problem of the starting frame deviating from its normal force. By setting a stabilizing component, a strong grip is provided at the moment the athlete exerts force to start running, which makes the starting frame firmly fixed to the ground, greatly reducing the problem of the starting frame deviating from its normal force due to the athlete's exertion, and ensuring that the athlete can obtain stable and effective support at the start.

[0017] Please see Figures 1-5 This utility model provides a technical solution: an easily adjustable sports starting device, including a starting frame 1 and an adjustment device 4. A base plate 2 is fixedly connected to one side of the starting frame 1, and toe plates 3 are slidably connected to both sides of the starting frame 1. The adjustment device 4 is set on the surface of the starting frame 1.

[0018] In this implementation scheme: the adjustment device 4 includes a strip sleeve 41, which is fixedly connected to the surface of the starting frame 1. A slider 44 is fixedly connected to one side of the toe plate 3. A groove is provided on the side of the starting frame 1 near the slider 44. The slider 44 is slidably connected to the starting frame 1. A fixing rod 45 is fixedly connected to the upper surface of the slider 44. A locking plate 46 is rotatably connected to one end of the fixing rod 45. By setting the adjustment device 4, when the user exerts force with his legs to start running, the slider 44 bears the main pressure, effectively reducing the stress on the telescopic rod 43. This greatly reduces the risk of damage to the cylinder 42 and the telescopic rod 43 due to excessive starting impact, extends the service life of the electric equipment, reduces the frequency of equipment maintenance and replacement, and ensures the stability and reliability of the starting device adjustment function.

[0019] Specifically, a cylinder 42 is fixedly connected to one side of the starting frame 1, and a telescopic rod 43 is fixedly installed on the drive end of the cylinder 42. By setting the telescopic rod 43, under the drive of the cylinder 42, the thrust generated by the cylinder 42 is converted into linear motion, which in turn pushes the toe plate 3 to slide along the starting frame 1, thereby achieving precise adjustment of the distance of the toe plate 3 and meeting the personalized needs of different athletes for starting posture.

[0020] Specifically, the end of the telescopic rod 43 away from the cylinder 42 passes through the starting frame 1 and is fixedly connected to the toe plate 3. There are two cylinders 42, which are arranged symmetrically.

[0021] Specifically, the surface of the strip sleeve 41 is provided with an arc-shaped groove 47. There are multiple arc-shaped grooves 47, which are arranged in a linear array along the strip sleeve 41. The clamping plate 46 is engaged with the arc-shaped groove 47.

[0022] Specifically, a stabilizing component 48 is provided on one side of the base plate 2. The stabilizing component 48 includes a restraint bar 482, which is fixedly connected to the starting frame 1. A knob 483 is rotatably connected to the surface of the restraint bar 482, and a pressure plate 481 is fixedly connected to the surface of the knob 483. By setting the stabilizing component 48, a strong grip is provided at the moment when the athlete exerts force to start running. This allows the starting frame 1 to be firmly fixed to the ground, greatly reducing the problem of the starting frame 1 deviating from its normal force due to the athlete's exertion, and ensuring that the athlete can obtain stable and effective support at the start.

[0023] Specifically, the lower surface of the pressure plate 481 is provided with a large number of conical teeth, and the surface of the restraint rod 482 is fixedly connected with a circular plate 485.

[0024] In this embodiment: by setting up a pressure plate 481, it can fit tightly against the ground under the elastic force generated by the torsion spring 484. This fitting action can effectively increase the friction between the pressure plate 481 and the ground, and the conical teeth at the bottom of the pressure plate 481 further enhance its contact effect with the ground, gripping the ground like a claw.

[0025] Specifically, a torsion spring 484 is fitted onto the surface of the restraint rod 482, and the two ends of the torsion spring 484 are fixedly connected to the circular plate 485 and the knob 483, respectively.

[0026] In this embodiment: by setting a torsion spring 484, when the starting frame 1 is placed on the ground, the elastic force generated by the torsion spring 484 causes the knob 483 to rotate, which in turn drives the pressure plate 481 to move towards the ground and fit tightly against the ground. This continuous squeezing force can ensure that the pressure plate 481 always keeps in contact with the ground, and enhance the friction between the starting frame 1 and the ground.

[0027] Working principle: By setting the adjustment device 4, when in use, the rotating plate 46 disengages from the arc groove 47, and then the cylinder 42 is activated. The cylinder 42 drives the telescopic rod 43 to press the toe plate 3 to slide along the starting frame 1. When the toe plate 3 reaches the appropriate distance, the rotating plate 46 abuts against the arc groove 47 to fix the slider 44. When the user exerts force with his legs, the slider 44 bears the pressure to reduce the force on the telescopic rod 43. By setting the adjustment device 4, when the user exerts force with his legs to start, the slider 44 bears the main pressure, effectively reducing the force on the telescopic rod 43. This greatly reduces the risk of damage to the cylinder 42 and the telescopic rod 43 due to excessive starting impact, extends the service life of the electric equipment, reduces the frequency of equipment maintenance and replacement, and ensures the stability and reliability of the starting device adjustment function. By setting up the stabilizing component 48, when the starting frame 1 is placed on the ground, the torsion spring 484 generates elastic force to compress the knob 483 to rotate. The knob 483 drives the pressure plate 481 to fit tightly against the ground. At the same time, the conical teeth at the bottom of the pressure plate 481 grip the ground firmly, providing grip when the user exerts force, reducing the problem of the starting frame 1 deviating from its normal force. By setting up the stabilizing component 48, a strong grip is provided at the moment the athlete exerts force to start running. This allows the starting frame 1 to be firmly fixed to the ground, greatly reducing the problem of the starting frame 1 deviating from its normal force due to the athlete's exertion, and ensuring that the athlete can obtain stable and effective support at the start.
