Description

Technical Field

[0001] The present invention relates to the technical field of cross-border alarms, and in particular to a cross-border alarm device. Background Art

[0002] In the field of sports competition and training, gymnastics trampoline, as a sport that combines both technical skills and entertainment, has become a dazzling pearl on the competitive stage with its agility and strength displayed when leaping, flipping, and spinning in the air. It also places extremely high demands on the comprehensive abilities of athletes. From a physical perspective, athletes need to have strong lower limb explosive power to obtain sufficient height to complete complex movements. At the same time, the control of the core muscles determines the stability of the posture in the air. From a technical perspective, the precise control of the movement trajectory and the connection skills between different movements require years of repeated training. The accuracy of the landing point plays a key role in this. It is not only related to the quality of the movement completion and the competition results, but also a core element to ensure competitive safety and show the aesthetics of competition.

[0003] However, when a trainee is competing, the landing point is also closely related to the score. If the landing point is not good, points may be deducted. However, during training and competition, athletes usually only deduct points when the landing point is relatively obvious. This results in athletes not being able to fully grasp the position where they have deviated from and thus unable to make good corrections. This patent is to provide a cross-border alarm device to alleviate the technical problems existing in the existing technology. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that, when a trainee is participating in a competition, the landing point is closely related to the score. If the landing point is not good, points may be deducted. However, during training and competition, athletes usually only lose points when the landing point is relatively obvious. This results in athletes being unable to fully grasp the position where they have deviated from and thus unable to make good corrections. Therefore, a cross-border alarm device is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cross-border alarm device comprises a support frame and a connecting box, a square groove is provided above the support frame, the square groove is fixedly connected to a four-corner frame, a bouncing block is provided at the opening of the four-corner frame, and a connecting rope is provided at the four corners of the bouncing block, the connecting rope is fixedly connected to the alarm mechanism, and the alarm mechanism is used to correct the landing point of the trainee, the alarm mechanism comprises a connecting box arranged inside the square groove, the connecting rope passes through the connecting box and is fixedly connected to the sliding block, the end of the sliding block away from the connecting rope is fixedly connected to a tension spring, the bottom of the sliding block is slidably connected to the first fixed block, the side of the first fixed block is fixedly connected to the second fixed block, the top of the second fixed block is slidably connected to a movable gear plate, the bottom of the movable gear plate is meshed with a gear, the side of the movable gear plate is fixedly connected to a connecting spring, the side of the second fixed block is fixedly connected to a support block, the support block is rotatably connected to a rotating disk, one side of the rotating disk is fixedly connected to an inclined U-frame, the side of the support block is provided with a knocking block for knocking the impact block, and the side of the movable gear plate is provided with an electric shock component, and the electric shock component is used to control the turning on and off of the indicator light.

[0007] The above technical solution further includes:

[0008] The electric shock assembly includes an outer sleeve arranged on the side of the movable tooth plate, a spring inside the outer sleeve is arranged, one end of the spring is fixedly connected to the inner tube, the inner tube is slidably connected to the outer sleeve, and the inner sleeve is fixedly connected to the electric shock block, and a closed circuit is formed when the inner tube contacts the electric shock block. When the athlete's landing point deviates on the bouncing block, driving the movable tooth plate to move, the inner tube overcomes the elastic force of the spring under the action of pressure and slides toward the inside of the outer sleeve until it contacts the electric shock block to form a closed circuit, thereby triggering the indicator light to light up. This design can convert the athlete's landing point deviation into an intuitive visual signal, so that referees and athletes can obtain landing point deviation information in a timely manner, facilitate quick judgment of whether the landing point is in the ideal area, and provide timely and clear feedback for landing point correction during training and competition.

[0009] The side of the support frame is fixedly connected to a side stabilizing frame, and the side of the support frame is fixedly connected to a sound amplifier, and the sound amplifier is used to amplify the sound when the knocking block hits the impact block. The side stabilizing frame can enhance the overall stability of the support frame, ensure that the device is firmly placed during athlete training and competition, and avoid affecting the monitoring accuracy due to the shaking of the device. The sound amplifier amplifies the sound produced by the knocking block hitting the impact block, providing the athlete with immediate auditory feedback. When the athlete's landing point deviates, causing the movable gear plate to move, and then the gear drives the tilted U-frame to move, and the knocking block hits the impact block to make a sound, the amplified sound can allow the athlete to perceive the landing point deviation more clearly, and adjust his own movements in time through sound prompts to achieve dynamic correction of the landing point position.

[0010] An opening cover is fixedly attached to the support frame, featuring cutouts of the same size as the openings in the four corner frames. This protects the device from foreign objects, preventing them from entering and disrupting the normal operation of its components, thereby ensuring the reliability and service life of the out-of-bounds alarm. Furthermore, the cutouts, designed to match the openings in the four corner frames, do not affect the normal operation and display of components such as the indicator lights, ensuring that the alarm signal generated by an athlete's landing point deviation is transmitted unimpeded, allowing referees and athletes to clearly observe the alarm.

[0011] The support frame is fixedly connected to a support arm on the side, which is used to support the camera. The support arm provides a stable mounting support structure for the camera, allowing the camera to record the athletes' training and competition processes at the appropriate angle and position.

[0012] The end of the connecting spring, distal from the movable tooth plate, is fixedly connected to the interior of the open tube. The connecting spring acts as a buffer and reset. When the movable tooth plate is forced to move due to an athlete's landing point deviation, the connecting spring is compressed, absorbing some of the impact force, preventing damage to components due to momentary excessive force and protecting the device's internal structure. Once the athlete's landing point returns to normal and the movable tooth plate is free of external force, the connecting spring releases its elastic potential energy, pushing the movable tooth plate back into position, allowing the device to quickly return to its initial monitoring state.

[0013] A plurality of alarm mechanisms are arranged around the bouncing block, and the alarm mechanisms are all connected to the bouncing block through connecting ropes.

[0014] The movable tooth plate is slidably connected to the second fixed block.

[0015] The side of the support frame is provided with multiple groups of videos for recording sports movements.

[0016] The present invention has the following beneficial effects:

[0017] In this invention, when an athlete's landing point deviates, the connecting rope pulls the movable toothed plate to trigger the electric shock component, illuminating the indicator light. Simultaneously, the knocking block strikes the impact block, producing a sound. This dual visual and auditory signal accurately indicates the exact direction of the landing point deviation. Compared to the traditional method of only deducting points for obvious landing point deviations, this method allows athletes to promptly and clearly understand the direction of deviation during training, eliminating blind training and effectively solving the problem of difficulty in grasping the location of deviation.

[0018] 2. In this invention, the device immediately activates an alarm mechanism if the athlete's landing point deviates slightly, breaking the limitations of traditional delayed feedback. Athletes can quickly adjust their movements and landing position based on immediate audio and visual cues, continuously strengthening correct landing control during training and avoiding the formation of incorrect movement habits. This significantly improves training effectiveness and alleviates the technical difficulty that athletes face in improving their competitive level due to the inability to promptly correct landing deviations.

The alarm mechanism includes a connecting box 9 provided inside the square groove 4, the connecting rope 13 passes through the connecting box 9 and is fixedly connected to the sliding block 11, and the end of the sliding block 11 away from the connecting rope 13 is fixedly connected to the tension spring 12, and the bottom of the sliding block 11 is slidably connected to the first The fixed block 10 has a second fixed block 14 fixedly connected to the side of the first fixed block 10, a movable tooth plate 15 is slidably connected above the second fixed block 14, a gear 16 is meshed and connected to the bottom of the movable tooth plate 15, a connecting spring 22 is fixedly connected to the side of the movable tooth plate 15, a supporting block 17 is fixedly connected to the side of the second fixed block 14, the supporting block 17 is rotatably connected to the rotating disk 19, and an inclined U-frame 18 is fixedly connected to one side of the rotating disk 19, a knocking block 20 for knocking the impact block 21 is provided on the side of the support block 17, and an electric shock component is provided on the side of the movable tooth plate 15, which is used to control the turning on and off of the indicator light 28.

[0030] In one embodiment, for the above-mentioned electric shock component, the electric shock component includes an outer sleeve 29 arranged on the side of the movable gear plate 15, and an inner tube spring 25 is arranged inside the outer sleeve 29. One end of the inner tube spring 25 is fixedly connected to the inner tube 24, and the inner tube 24 is slidingly connected to the outer sleeve 29. The outer sleeve 29 is fixedly connected to the electric shock block 26, and a closed circuit is formed when the inner tube 24 contacts the electric shock block 26.

[0031] In this embodiment, when an athlete's landing point deviates on bouncing block 6, driving movable toothed plate 15 to move, inner tube 24, under pressure, overcomes the elastic force of inner spring 25 and slides toward outer tube 29 until it contacts contacting contact block 26, forming a closed circuit and triggering indicator light 28 to illuminate. This design converts an athlete's landing point deviation into an intuitive visual signal, allowing referees and athletes to obtain timely landing point deviation information, facilitating quick judgment of whether the landing point is within the ideal range, and providing timely and clear feedback for correcting landing points during training and competition.

[0032] In one embodiment, for the above-mentioned support frame 1, a side stabilizing frame 2 is fixedly connected to the side of the support frame 1, and a sound amplifier 3 is fixedly connected to the side of the support frame 1.

[0033] In this embodiment, the side stabilizer 2 can enhance the overall stability of the support frame 1, ensuring that the device is firmly placed during athlete training and competition, and preventing the monitoring accuracy from being affected by the shaking of the device. The sound amplifier 3 amplifies the sound produced by the knocking block 20 hitting the impact block 21, providing the athlete with immediate auditory feedback. When the athlete's landing point deviates, causing the movable tooth plate 15 to move, and then the gear 16 drives the tilted U-frame 18 to move, and the knocking block 20 hits the impact block 21 to make a sound, the amplified sound can allow the athlete to perceive the landing point deviation more clearly, and adjust their own movements in time through sound prompts, thereby achieving dynamic correction of the landing point position.

[0034] In one embodiment, the opening cover plate 5 is fixedly connected to the top of the support frame 1 , and a cutout having the same size as the openings of the four corner frames 27 is opened on the surface of the opening cover plate 5 .

[0035] In this embodiment, the opening cover 5 serves as a protective barrier, preventing foreign matter from entering the device and affecting the normal operation of its components, thereby ensuring the reliability and service life of the cross-border alarm device. Furthermore, the cutouts designed to match the openings of the quadrangular frame 27 do not affect the normal operation and signal display of components such as the indicator light 28, ensuring that the alarm signal generated when an athlete's landing point deviates can be transmitted unimpeded, allowing the referee and athletes to clearly observe the alarm.

[0036] In one embodiment, for the above-mentioned support frame 1 , a support arm 7 is fixedly connected to the side of the support frame 1 , and the support arm 7 is used to support the camera 8 .

[0037] In this embodiment, the support arm 7 provides a stable mounting support structure for the camera 8, so that the camera 8 can record the training and competition process of the athletes at a suitable angle and position.

[0038] In one embodiment, for the connecting spring 22 , one end of the connecting spring 22 away from the movable tooth plate 15 is fixedly connected to the inside of the open tube 23 .

[0039] In this embodiment, the coupling spring 22 acts as a buffer and reset mechanism. When the movable toothed plate 15 is forced to move due to an athlete's landing point deviation, the coupling spring 22 is compressed, absorbing some of the impact force, preventing damage to components due to momentary excessive force, and protecting the device's internal structure. Once the athlete's landing point returns to normal and the movable toothed plate 15 is freed from the external force, the coupling spring 22 releases its elastic potential energy, pushing the movable toothed plate 15 back into its original position, allowing the device to quickly return to its initial monitoring state.

[0040] A plurality of alarm mechanisms are arranged around the bouncing block 6 , and the alarm mechanisms are all connected to the bouncing block 6 via connecting ropes 13 .

[0041] In one embodiment, for the movable tooth plate 15 , the movable tooth plate 15 is slidably connected to the second fixed block 14 .

[0042] In one embodiment, for the above-mentioned support frame 1, multiple groups of video recordings for recording sports movements are provided on the side of the support frame 1.

[0043] The working principle of the cross-border alarm device of the present invention is as follows: first, take the training before a gymnastics competition as an example. The trainee steps on the top of the bouncing block 6. The bouncing block 6 is marked with a line. That is, if the trainee does not leave the center position, he will get a high score. However, if a trainee steps on the position of the center circle of the bouncing block 6, there will be a difference. For example, if the trainee steps on one side of the center position, the score will not be as high as if the trainee stood in the middle. Therefore, when the trainee steps on the surface of the bouncing block 6, when the trainee approaches one side of the connecting box 9, the pressure on the connecting rope 13 on the side of the connecting box 9 will be greater, so at this time, the trainee will not get a high score. The connecting rope 13 will pull the sliding block 11 and the tension spring 12, and the sliding block 11 will push the movable tooth plate 15 originally set above the first fixed block 10 to above the second fixed block 14. At this time, the connecting spring 22 on the side of the movable tooth plate 15 is compressed, and then the movable tooth plate 15 pushes the inner tube 24 to slide inside the outer sleeve 29, and then the inner tube 24 pushes the inner spring 25 to compress. At this time, since the side of the inner tube 24 touches the electric shock block 26, the referee can see that the indicator light 28 lights up, which means that it is in the center position but not in the high-scoring center position. The arrangement ensures that a single trainer can let the referee know when training, which is convenient for correction and thus obtains high scores. In addition, when the athlete steps on the bouncing block 6, the connecting rope 13 is pulled to push the movable tooth plate 15 to move. The movable tooth plate 15 originally slides above the first fixed block 10. When the connecting rope 13 drags the sliding block 11 to push the movable tooth plate 15 to slide above the second fixed block 14, the movable tooth plate 15 slides and engages with the gear 16. The gear 16 rotates to lift one end of the inclined U frame 18 to the inclined U frame 18. The next section is a cycle. When the mobile toothed plate 15 passes over the gear 16, the gear 16 will lift one end of the inclined U-frame 18, so that the knocking block 20 knocks on the surface of the impact block 21. Then, when the mobile toothed plate 15 passes over the gear 16, one end of the inclined U-frame 18 is lifted, so that the knocking block 20 no longer knocks. At this time, the mode can be adjusted by turning on or off the sound amplifier 3. Turning on the sound amplifier 3 means that the knocking block 20 knocking on the impact block 21 can be heard by the athletes, and turning it off can prevent the knocking sound from affecting the trainers.

[0044] By setting a smaller range in the center of the bouncing block 6 as a standard value, when the athlete deviates from the center position by stepping on the bouncing block 6, the indicator lights 28 and the knocking block 20 around it knock the impact block 21 to determine the direction of the deviation, thereby facilitating the athlete's subsequent training.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
