Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a take-off board. Background Technology

[0002] A take-off board is a piece of equipment used by athletes in track and field, diving, and other sports when they take off. In track and field, the take-off board is an indispensable key piece of equipment in events such as the long jump and triple jump. At the moment of take-off, athletes use the reaction force generated by the take-off board to obtain sufficient take-off height and horizontal speed, thereby achieving a greater jump distance. Its performance directly affects the athlete's performance.

[0003] The existing springboard has the following shortcomings:

[0004] On the one hand, to enhance the anti-slip effect, anti-slip mats are usually pasted on the surface of the take-off board. However, with long-term and frequent use, the anti-slip mats will inevitably wear down. However, the existing take-off boards lack a structure for easy replacement of the anti-slip mats. Once the anti-slip mats are severely worn, athletes face the risk of slipping and falling. It also requires a lot of time and manpower to remove the old anti-slip mats and install new ones, which is extremely inconvenient. On the other hand, the existing take-off board elastic components are simple in construction and the elasticity is fixed and cannot be adjusted. Different athletes have different weights, strengths, and take-off habits. The simple elastic components cannot adjust the elasticity according to these individual factors, making it difficult for athletes to find the take-off elasticity that best suits them. This seriously affects the take-off effect and is not conducive to the efficient use of the take-off board.

[0005] Therefore, we propose a springboard to address the problems mentioned above. Utility Model Content

[0006] This invention uses a U-shaped locking plate that slides onto both ends of an arc-shaped elastic plate. By using a knob one in conjunction with a threaded post and a threaded sleeve, the anti-slip pad can be easily tightened and loosened. Rotating a knob two drives a transmission screw, which moves the sliding guide post and the sliding push plate, changing the compression degree of the spring two, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a starting board, including a supporting base plate, an arc-shaped elastic plate rotatably hinged to the right end of the supporting base plate, an anti-slip pad provided above the outer surface of the arc-shaped elastic plate, fastening mechanisms provided at both the left and right ends of the arc-shaped elastic plate, and an elastic component fixedly connected to the right end of the supporting base plate.

[0008] The fastening mechanism includes U-shaped clamping plates, two of which are slidably clamped onto the left and right ends of the arc-shaped elastic plate. Threaded sleeves are fixedly connected to both the front and rear ends of the U-shaped clamping plates. Connecting ear plates are fixedly connected to both the left and right ends of the front and rear surfaces of the arc-shaped elastic plate. A knob is movably connected to the opposite surfaces of the two connecting ear plates. A threaded column is fixedly connected to the side of the knob near the threaded sleeve. The end of the threaded column away from the knob extends through to the middle of the threaded sleeve and is threadedly connected to the inner surface of the threaded sleeve.

[0009] Preferably, the left end of the supporting base plate is provided with a movable connecting groove, and the bottom left side of the arc-shaped elastic plate is fixedly connected to a movable connecting frame, which is movably hinged inside the movable connecting groove.

[0010] Preferably, the elastic component includes a connecting plate, which is fixedly connected to the right end of the supporting base plate. Three lower limit platforms are fixedly connected to the top of the connecting plate, and a spring is fixedly connected to the top of the lower limit platforms. Three upper limit platforms are fixedly connected to the bottom right side of the arc-shaped elastic plate, and the top of the spring is connected to the bottom of the upper limit platform.

[0011] Preferably, three sliding guide posts are slidably inserted into the left side of the connecting plate, and a sliding push plate is slidably connected to the outer surface of the three sliding guide posts. Three springs are fixedly connected to the right side of the sliding push plate. The springs are disposed on the outer surface of the sliding guide posts and their right ends are fixedly connected to the left side of the connecting plate. Push rods are movably hinged to both the front and rear sides of the left side of the sliding push plate. The top of the push rods is movably hinged to the middle of the lower surface of the arc-shaped elastic plate.

[0012] Preferably, the sliding guide post has a limit slide plate fixedly connected to both the front and rear sides of the right side of its outer surface, and a transmission screw is threadedly connected to the middle of the right end of the sliding guide post, and a knob is fixedly connected to the right end of the transmission screw.

[0013] Preferably, the connecting plate has three connecting grooves on its right side, and the inner surface of the connecting grooves has limit grooves on both the front and rear sides. The right end of the sliding guide post extends into the interior of the connecting groove, and the outer surface of the limit slide plate is slidably connected to the inner surface of the limit groove. The second knob is located on the right side of the connecting plate.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. In this utility model, a U-shaped clamping plate is slidably engaged with both ends of an arc-shaped elastic plate. Rotating knob one causes the threaded post to rotate within the threaded sleeve, thereby allowing the U-shaped clamping plate to tighten or loosen the anti-slip pad on the arc-shaped elastic plate. When the anti-slip pad is worn and needs to be replaced, simply rotate knob one in the opposite direction to disengage the threaded post from the threaded sleeve, releasing the U-shaped clamping plate from the anti-slip pad. The old anti-slip pad can then be easily removed and replaced with a new one. This structure greatly improves the convenience of replacing the anti-slip pad, saves replacement time and labor costs, reduces the risk of athletes slipping due to worn anti-slip pads, and ensures the safety of athletes during training and competition.

[0016] 2. In this utility model, rotating the second knob drives the transmission screw to rotate, which in turn drives the sliding guide post to slide left and right within the connecting groove. The sliding guide post drives the sliding push plate to move, changing the compression degree of the second spring. This, in turn, changes the elasticity of the arc-shaped elastic plate through the push rod. Different athletes can independently adjust the elasticity of the take-off board according to their own weight, strength, and jumping habits. This adjustable elastic component can meet the personalized needs of different athletes, helping them find the most suitable take-off elasticity, significantly improving the take-off effect, and facilitating the efficient use of the take-off board.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution: it includes a supporting base plate 1, an arc-shaped elastic plate 2 is rotatably hinged to the right end of the supporting base plate 1, an anti-slip pad 3 is provided above the outer surface of the arc-shaped elastic plate 2, fastening mechanisms 4 are provided at both the left and right ends of the arc-shaped elastic plate 2, an elastic component 5 is fixedly connected to the right end of the supporting base plate 1, the fastening mechanism 4 includes a U-shaped clamping plate 41, two U-shaped clamping plates 41 are slidably clamped to the left and right ends of the arc-shaped elastic plate 2 respectively, threaded sleeves 42 are fixedly connected to both the front and rear ends of the U-shaped clamping plate 41, connecting ear plates 43 are fixedly connected to both the left and right ends of the front and rear surfaces of the arc-shaped elastic plate 2, a knob 44 is movably connected to the opposite surface of the two connecting ear plates 43, a threaded column 45 is fixedly connected to the side of the knob 44 near the threaded sleeve 42, and the end of the threaded column 45 away from the knob 44 passes through to the middle of the threaded sleeve 42 and is threadedly connected to the inner surface of the threaded sleeve 42;

[0026] The overall effect of Embodiment 1 is as follows: In actual use, when it is necessary to install the anti-slip mat 3, place the anti-slip mat 3 on the upper surface of the arc-shaped elastic plate 2, align the U-shaped clamping plate 41 with both ends of the arc-shaped elastic plate 2 and slide it in, rotate the knob 44, and the threaded post 45 screws into the threaded sleeve post 42. The U-shaped clamping plate 41 gradually presses the anti-slip mat 3 to achieve a firm installation. When the anti-slip mat 3 is worn and needs to be replaced, follow the reverse operation to easily remove the old anti-slip mat 3 and replace it with a new one. This greatly improves the replacement efficiency of the anti-slip mat 3 and reduces the safety hazards and time costs caused by the anti-slip mat 3.

[0027] Example 2: As Figure 3 , Figure 4 and Figure 5As shown, this utility model provides a technical solution: a movable connecting groove 11 is provided at the left end of the supporting base plate 1; a movable connecting frame 21 is fixedly connected to the bottom left side of the arc-shaped elastic plate 2; the movable connecting frame 21 is movably hinged inside the movable connecting groove 11; the elastic component 5 includes a connecting plate 51, which is fixedly connected to the right end of the supporting base plate 1; three lower limit platforms 52 are fixedly connected to the top of the connecting plate 51; a spring 53 is fixedly connected to the top of the lower limit platforms 52; three upper limit platforms 22 are fixedly connected to the bottom right side of the arc-shaped elastic plate 2; the top of the spring 53 is connected to the bottom of the upper limit platform 22; three sliding guide posts 54 are slidably inserted into the left side of the connecting plate 51; a sliding push plate 55 is slidably connected to the outer surface of the three sliding guide posts 54; three springs 56 are fixedly connected to the right side of the sliding push plate 55; and springs 56... 56 is set on the outer surface of the sliding guide post 54 and its right end is fixedly connected to the left side of the connecting plate 51. Push rods 57 are movably hinged on both the front and rear sides of the left side of the sliding push plate 55. The top of the push rods 57 is movably hinged to the middle of the lower surface of the arc-shaped elastic plate 2. Limiting slide plates 541 are fixedly connected on both the front and rear sides of the right side of the outer surface of the sliding guide post 54. A transmission screw 542 is threadedly connected to the middle of the right end of the sliding guide post 54. A knob 543 is fixedly connected to the right end of the transmission screw 542. Three connecting grooves 511 are opened on the right side of the connecting plate 51. Limiting grooves 512 are opened on both the front and rear sides of the inner surface of the connecting grooves 511. The right end of the sliding guide post 54 passes through the interior of the connecting grooves 511. The outer surface of the limiting slide plate 541 is slidably connected to the inner surface of the limiting groove 512. Knob 543 is set on the right side of the connecting plate 51.

[0028] The overall effect of Embodiment 2 is as follows: Before use, athletes can adjust the elasticity according to their own situation. For example, athletes with a larger body weight can rotate knob 2 543 clockwise, causing the transmission screw 542 to drive the sliding guide post 54 to slide to the right, and the sliding push plate 55 to move to the right, further compressing the spring 2 56. The force of the push rod 57 pushing the arc-shaped elastic plate 2 upward increases, and the elasticity of the arc-shaped elastic plate 2 is enhanced, providing the athlete with a greater reaction force. Athletes with a lighter body weight can rotate knob 2 543 counterclockwise to appropriately relax the spring 2 56, reduce the elasticity of the arc-shaped elastic plate 2, meet the personalized needs of different athletes, and improve the take-off effect.

[0029] The working principle of the entire device is as follows: During the take-off process, the athlete steps onto the curved elastic plate 2. The curved elastic plate 2 rotates and presses down around the hinge point between the movable connecting frame 21 and the movable connecting groove 11. Spring 1 53 and Spring 2 56 are compressed and undergo elastic deformation, storing elastic potential energy. At the moment of take-off, Spring 1 53 and Spring 2 56 release elastic potential energy, pushing the curved elastic plate 2 upward, giving the athlete an upward and forward reaction force, helping the athlete to obtain take-off height and horizontal speed. At the same time, the anti-slip mat 3 provides stable friction throughout the process to prevent the athlete from slipping. If the anti-slip mat 3 is worn, it can be easily replaced through the fastening mechanism 4. When replacing, first turn the knob 1 44 counterclockwise. As the knob 44 rotates, the threaded post 45 gradually retracts from the threaded sleeve 42, causing the U-shaped clamping plate 41 to gradually reduce its clamping force on the arc-shaped elastic plate 2. When the threaded post 45 completely retracts from the threaded sleeve 42, the U-shaped clamping plate 41 can easily slide out from both ends of the arc-shaped elastic plate 2, thereby releasing the old anti-slip pad 3 from its fixation and removing it. Then, place the new anti-slip pad 3, align the U-shaped clamping plate 41 with the slots at both ends of the arc-shaped elastic plate 2, slide it into place, and then rotate the knob 44 clockwise. The threaded post 45 screws into the threaded sleeve 42, and the U-shaped clamping plate 41 gradually presses the new anti-slip pad 3, completing the replacement operation. If the athlete needs to adjust the elasticity, this can be achieved through the adjustment structure of the elastic component 5.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
