Since this device is placed externally, it is protected from accidental collisions by the display protection frame 10, which is used to protect the electronic recording display 11. Photos or videos captured by the recording camera 21 are also 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 existing technologies, and the specific working principles are not described in detail here). The device can also be used to help people stick on the sprint red line. Simply use tape to stick it on the outside of frame 1 3 and frame 2 4. People only need to install and adjust the device before the competition, and the competition time is long and continuous. This makes it convenient to use and record.

The outer wall of the spring 23 is fixedly connected to the left side of the push plate 22. A plurality of convex teeth 28 are evenly arranged on the outer wall of the adjusting plate 12. The rotating rod When the gear 27 rotates, it will drive the adjusting plate 12 to move vertically upward along the track 35 and stop when it reaches a suitable height. When the pulley 2 33 rotates, it will drive the pulley 1 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, making it closer to the runway and making the recording clearer. When the device is finished using, the adjusting plate 12 can be retracted by rotating the motor 29 in the direction. When the convex point of the cam 24 does not contact the push plate 22, the spring 23 will pull the push plate 22 to return to its initial position.

[0025] Working principle of the present invention:

[0026] Before a running competition, the placement board 1 and the placement board 2 are placed on both sides of the outside of the runway finish line, and then the fixed pressure rod 5 is used to press them into the grass on both sides to limit the placement board 1 and the placement board 2, and then the telescopic plate 6 is pulled to make its height equal to the adjustment plate 12. After the height is equal, the position of the telescopic plate 6 can be fixed by inserting the clamping rod 9 into the corresponding through-hole 1 7 and through-hole 2 8, and then the rotating plate 13 is rotated to make it contact with the telescopic plate 6, and then the mounting bolts 15 are connected to the telescopic plate 6 through the corresponding threaded holes 14 (the width of local runways is different, and multiple threaded holes 14 can improve the adjustability of the distance between the placement board 1 and the placement board 2), and then the reciprocating screw 34 is driven to rotate by the motor 19, and the reciprocating screw 34 drives the test camera 18 to reciprocate, thereby increasing the coverage area of ​​the test camera 18. The test camera 18 is mainly used to The result check is used to assist in body position judgment. The infrared electronic tester 25 is used to record the time when the person passes the finish line. The test results will be displayed on the electronic recording display 11, making it convenient for people to view the results. Since this device is placed outside, it can 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 existing technologies, and the specific working principles are not described in detail here). In addition, this device can be used to help people stick the sprint red line. It only needs to be affixed to the outside of the frame 1 3 and the frame 2 4 with tape. People only need to install and adjust the device before the competition. The competition time is very long and continuous, which makes it easy to use and record.

[0027] After the placement plate 1 is placed, when adjusting the adjustment plate 12, the motor 29 drives the pulley 2 33 and the gear 27 to rotate. When the gear 27 rotates, it drives the adjustment plate 12 to move through the convex teeth 28. The adjustment plate 12 will move vertically upward along the track 35 and stop when it reaches a suitable height. When the pulley 2 33 rotates, it drives the pulley 1 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, making it closer to the runway and making the recording clearer. When the device is finished using, the adjustment plate 12 can be retracted by rotating the motor 29 in the direction. When the convex point of the cam 24 does not contact the push plate 22, the spring 23 will pull the push plate 22 to return to its initial position.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
