[0002] When the school organizes a sports meet, there will be a long jump competition. The long jump process is that students jump out from the take-off position and land in the sand pool. When measuring the results, the first landing point and the initial position are measured.

[0003] A sports long jump measuring device is disclosed in the Chinese Public Application No.: CN220176006U, which relates to the field of sports devices. The sports long jump measuring device includes a sand pit platform with a sand pit body, a measuring ruler is provided on one side of the sand pit platform, a laser transmitter is provided on the other side of the sand pit platform, a guide rail is provided at the bottom of the laser transmitter, a positioning reference column is provided in the sand pit body, a laser alignment groove is provided on the positioning reference column, and a level bubble is provided on the top of the positioning reference column. During the measurement process, the sports long jump measuring device uses the setting of a measuring ruler, a positioning reference column and a laser transmitter to replace the traditional leather tape measurement method. The measurement process is more accurate, the level bubble is used to ensure that the positioning reference column is in a vertical state, and the long jump value is read by the reading of the laser transmitter on the measuring ruler. The method of measuring the long jump distance is simple and convenient, and can be operated by one person.

At this time, the bottom of the second rake tooth corresponds to the bottom of the first rake tooth.

[0023] S4: After the measurement is completed, the first screw rod and the second screw rod are driven to reverse, and then the paving moving seat and the measuring moving seat are moved away from each other, and then the pointer is reset and flipped upward, and the paving frame drives the first rake teeth and the second rake teeth to spread the sand. When the paving moving seat moves to the initial position, one end of the driving block will touch the fixed seat close to the first motor, and then the lifting plate is driven to rise again, and the second rake teeth are driven to rise again, preparing for the next sand combing.

At this time, the first locking tooth (29) and the second locking tooth (33) are engaged and locked, and then the first screw (10) continues to rotate. At this time, the outer rod (20) remains stationary, and the driving rod (19) approaches the torsion spring (24). Under the cooperation of the guide block (28) and the first guide groove (27), the inner cylinder (22) rotates, the torsion spring (24) twists, and then the inner cylinder (22) drives the pointer (8) to rotate, and one end of the pointer (8) corresponds to the scale plate (5), and then the distance is measured; S3: When the water flow direction measurement movable seat (17) is displaced, it will drive the paving frame (12) and the first rake tooth (18) to move as a whole. One end of the initial lifting plate (31) is located at the top of the driving block (34) close to the end of the first motor (13), so the bottom of the second rake tooth (32) is higher than the bottom of the first rake tooth (18). When the paving movable seat (16) drives the paving frame (12) to approach the outer rod (20), the first rake tooth (18) combs the sand in the sand pool (1). When the paving movable seat (16) contacts the outer rod (20), the driving plate (21) pushes the driving block (34) to move. The driving block (34) guides the lower spring (38) through the slope at one end of the second guide groove (35) to reset the lifting plate (31) to move downward. At this time, the bottom of the second rake tooth (32) corresponds to the bottom of the first rake tooth (18); S4: After the measurement is completed, the first screw rod (10) and the second screw rod (11) are driven to reverse, and then the spreading movable seat (16) and the measuring movable seat (17) are moved away from each other, and then the pointer (8) is reset and flipped upward, and the spreading frame (12) drives the first rake teeth (18) and the second rake teeth (32) to spread sand. When the spreading movable seat (16) moves to the initial position, one end of the driving block (34) will touch the fixed seat (9) close to the first motor (13), and then the lifting plate (31) is driven to rise again, and the second rake teeth (32) are driven to rise again, so as to prepare for the next sand combing.
