An electronic recording display 11 is fixedly connected to the left side wall of the first frame 3. A display protection frame 10 is fixedly sleeved on the outer side wall of the electronic recording display 11. An adjusting device is provided inside the first frame 3. A rotating plate 13 is rotatably connected to the top of the adjusting plate 12. The rotating plate 13 is provided with a plurality of threaded holes 14. The rotating plate 13 is connected to the top of the telescopic plate 6 through the threaded holes 14. A first fixing plate 16 is fixedly connected to the bottom of the rotating plate 13. A second fixing plate 17 located on the right side of the first fixing plate 16 is fixedly connected to the bottom of the rotating plate 13.

The diameters of the plurality of second through holes 8 and the first through holes 7 are all equal to the diameter of the clamping rod 9. Before a running race, the first placement board 1 and the second placement board 2 are placed on both sides outside the end of the runway. Subsequently, the fixed pressure rods 5 are pressed into the grass on both sides to limit the first placement board 1 and the second placement board 2. Then, the telescopic plate 6 is pulled to make its height equal to that of the adjusting plate 12. After the heights are equal, the position of the telescopic plate 6 can be fixed by inserting the clamping rod 9 into the corresponding first through holes 7 and second through holes 8. Then, the rotating plate 13 is rotated to make it contact with the telescopic plate 6. Subsequently, the mounting bolt 15 is connected to the telescopic plate 6 through the corresponding threaded hole 14 (the widths of local runways are different, and the plurality of threaded holes 14 can improve the adjustability of the distance between the first placement board 1 and the second placement board 2). Then, the motor 19 drives the reciprocating screw rod 34 to rotate, and the reciprocating screw rod 34 drives the test camera 18 to perform reciprocating motion, thereby increasing the coverage area of the test camera 18. The test camera 18 mainly plays an auxiliary role in body position judgment for result inspection.The infrared electronic tester 25 is used to record the time when personnel pass the finish line. The test results will be displayed on the electronic recording display 11 for easy viewing by personnel. Since this device is placed outside, to avoid accidental collision, the display protection frame 10 is used to protect the electronic recording display 11. The photos or videos taken by the recording camera 21 will also be transmitted to the electronic recording display 11 (the electronic recording display 11, the infrared electronic tester 25, the test camera 18, and the recording camera 21 are all prior arts, and their specific working principles will not be elaborated here). Moreover, this device can cooperate with people to paste the sprint red line, and only need to stick it on the outer sides of the frame one 3 and the frame two 4 with tape. Personnel only need to install and adjust the device before the competition, and the competition time is long and continuous, so it can be convenient to use and convenient to record.

[0020] The adjusting device includes a motor 29. The motor 29 is fixedly connected to the outer side wall of the frame one 3. The driving end of the motor 29 slidably penetrates through the outer side wall of the frame one 3 and is fixedly connected to a first rotating rod 30. The inner side wall of the frame one 3 is rotatably connected to a second rotating rod 31. A first pulley 32 is fixedly connected to the outer side wall of the second rotating rod 31. A second pulley 33 is fixedly connected to the outer side wall of the first rotating rod 30. The first pulley 32 is connected to the second pulley 33 through a belt 26. A gear 27 is fixedly connected to the outer side wall of the second pulley 33. A plurality of convex teeth 28 are fixedly connected to the outer side wall of the adjusting plate 12. The gear 27 meshes with the convex teeth 28. A cam 24 is fixedly connected to the outer side wall of the first pulley 32. A spring 23 is fixedly connected to the top of the first placing plate 1. The outer side wall of the spring 23 is fixedly connected to the left side of the pushing plate 22. The plurality of convex teeth 28 are evenly arranged on the outer side wall of the adjusting plate 12. The first rotating rod 30 is located directly above the second rotating rod 31. After the first placing plate 1 is placed, when adjusting the adjusting plate 12, the motor 29 drives the second pulley 33 and the gear 27 to rotate. When the gear 27 rotates, it will drive the adjusting plate 12 to move through the convex teeth 28. The adjusting plate 12 will move vertically upward along the track 35. When it moves to an appropriate height, it can stop. When the second pulley 33 rotates, it will drive the first pulley 32 and the cam 24 to rotate through the belt 26. When the convex point of the cam 24 contacts the pushing plate 22, it will push the pushing plate 22 along the limiting frame 20, so as to change the horizontal position of the recording camera 21 through the pushing plate 22, making it closer to the runway and making the recording clearer. When the device is used up, the adjusting plate 12 can be retracted by rotating the motor 29 in the reverse direction. When the convex point of the cam 24 does not contact the pushing plate 22, the spring 23 will pull the pushing plate 22 back to the initial position.

[0021] The working principle of the present invention: Before a running race, place the first placement board 1 and the second placement board 2 on both sides outside the end of the runway. Then, press them into the grass on both sides through the fixed pressure rod 5 to limit the first placement board 1 and the second placement board 2. Next, pull the telescopic board 6 to make its height equal to that of the adjustment board 12. After the heights are equal, insert the clamping rod 9 into the corresponding first through hole 7 and second through hole 8 to fix the position of the telescopic board 6. Then, rotate the rotating board 13 to make it contact with the telescopic board 6. Subsequently, connect the mounting bolt 15 to the telescopic board 6 through the corresponding threaded hole 14 (the widths of local runways vary, and multiple threaded holes 14 can improve the adjustability of the distance between the first placement board 1 and the second placement board 2). Then, drive the reciprocating screw rod 34 to rotate through the motor 19, and the reciprocating screw rod 34 drives the test camera 18 to perform reciprocating motion, thereby increasing the coverage area of the test camera 18. The test camera 18 mainly plays an auxiliary role in judging the body position for result inspection. The infrared electronic tester 25 is used to record the time when personnel pass the finish line. The test results will be displayed on the electronic recording display 11 for personnel to conveniently view the results. Since this device is placed outside, the display protection frame 10 is used to protect the electronic recording display 11 to avoid accidental collision. The photos or videos taken by the recording camera 21 will also be transmitted to the electronic recording display 11 (the electronic recording display 11, infrared electronic tester 25, test camera 18, and recording camera 21 are all prior arts, and the specific working principles will not be described in detail here). Moreover, this device can cooperate with people to paste the sprint red line, and only need to stick it on the outside of the first frame 3 and the second frame 4. Personnel only need to install and adjust the device before the race, and the race time is long and continuous, so it can be convenient to use and convenient to record; After the first placement board 1 is placed, when adjusting the adjustment board 12, drive the second pulley 33 and the gear 27 to rotate through the motor 29. When the gear 27 rotates, it will drive the adjustment board 12 to move through the convex teeth 28, and the adjustment board 12 will move vertically upward along the track 35. Stop when it moves to the appropriate height. When the second pulley 33 rotates, it will drive the first pulley 32 and the cam 24 to rotate through the belt 26. When the convex point of the cam 24 contacts the push plate 22, it will push it along the limit frame 20, thereby changing the horizontal position of the recording camera 21 through the push plate 22 to make it closer to the runway and make the recording clearer. When the device is used up, rotate the motor 29 in the opposite direction to contract the adjustment board 12. When the convex point of the cam 24 does not contact the push plate 22, the spring 23 will pull the push plate 22 back to its initial position.

[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
