When measuring forward flexion, the push plate 309 moves with the tester's movements, and the infrared sensor 3010 on the inside determines the displacement data by emitting infrared rays and detecting changes in the blocked situation, and converts it into a forward flexion measurement result, which provides quantitative data support for evaluating the student's physical flexibility.

[0035] A square groove 12 and a square groove 2 16 are respectively provided on the top and the rear side of the connecting plate 2, and a clamping mechanism 8 is provided inside the square groove 12 and the square groove 2 16. The clamping mechanism 8 includes a bottom plate 801, and the bottom plate 801 is provided on the inner bottom wall of the square groove 12 and the square groove 2 16. Two rotating plates 805 are provided on the top of the bottom plate 801, and two annular clamps 804 are rotatably connected between the rotating plates 805. A triangular plate 803 is provided on the outer side of the annular clamps 804, and a spring 1 802 is provided between the bottom of the triangular plate 803 and the bottom plate 801. A plurality of arc-shaped clamping blocks 302 are provided on the front side of the measuring plate 1 301, and the arc-shaped clamping blocks 302 are all clamped with the corresponding annular clamps 804. The clamping mechanism 8 uses the spring 1 802 to make the annular clamps 804 and The arc-shaped clamping block 302 is tightly engaged, so as to realize the stable connection and positioning of the measuring plate 1 301 and the connecting plate 2 2 at different measuring positions, ensure the fixed position of the measuring plate 1 301 during the measurement process, improve the measurement accuracy and reliability, and facilitate the switching of the measurement mode.

The terminal 503 processes, stores, analyzes and displays the results of the data, so as to facilitate physical education teachers to obtain data and evaluate students' physical fitness based on the data, and provide a basis for teaching decisions.

[0036] Please see attached Figure 5 -Attached Fig. 9, a storage pad mechanism 4 is provided on the inner side of the connecting plate 1, and the storage pad mechanism 4 includes a rotating shaft 401, which is rotatably connected to the inside of the connecting plate 1, and the rotating shaft 401 is connected to the pull plate 403 through a silicone pad 402. A handle 405 is provided on the outer end of the rotating shaft 401, and a cylindrical hole 404 is provided on the inner side of the handle 405. The rotating shaft 401 enables the pull plate 403 to be rotated around it to be unfolded or stored. The silicone pad 402 buffers the rotation impact of the pull plate 403 and provides a certain friction force to assist in fixing the position. The handle 405 facilitates the operation of the pull plate 403 to rotate, and the cylindrical hole 404 cooperates with the buckle mechanism 9 to fix the pull plate 403 when storing. When the storage pad is needed, such as when students perform certain test actions that require auxiliary protection or a comfortable experience, the pull plate 403 can be unfolded to improve the flexibility and humanization of the tester. A snap mechanism 9 is arranged on the side, and the snap mechanism 9 includes a square box 901, and the square box 901 is arranged on the inner wall of the connecting plate 1. A slider 902 is slidably arranged inside the square box 901, and a spring 903 is arranged between the slider 902 and the square box 901. A clamping rod 904 and a slide plate 905 are respectively arranged on the outer side of the slider 902, and the clamping rod 904 is engaged with the cylindrical hole 404. The snap mechanism 9 uses the spring 903 to make the clamping rod 904 insert into the cylindrical hole 404 under normal conditions to fix the pull plate 403 and the connecting plate 1, prevent the pull plate 403 from rotating at will, and ensure that the tester has a compact and stable structure when the storage pad is not in use; when the storage pad needs to be operated, the slide plate 905 is pulled to drive the slider 902 to overcome the elastic force of the spring 903 to make the clamping rod 904 disengage from the cylindrical hole 404, which is convenient to operate and effectively manages the state of the storage pad mechanism 4.

[0037] Working principle: When the physical education comprehensive tester is used for measurement, when the measuring board 301 is in the initial state perpendicular to the connecting board 1, the height measurement mode is turned on. At this time, the ultrasonic sensor 305 located on the inner side of the measuring board 304 is started. When encountering the obstacle of the human head, a reflection phenomenon occurs. The reflected wave is captured by the receiving device of the ultrasonic sensor 305, and the vertical distance from the human head to the ultrasonic sensor 305 can be quickly and accurately calculated, which is the measured height data;

[0038] At the same time, the second measuring plate 303 can be flexibly slid and adjusted inside the first measuring plate 301. It is designed with a plurality of equally spaced circular holes 3011. By engaging the latch 306 with the circular holes 3011 at different positions, the extended length of the second measuring plate 303 can be effectively changed, thereby accurately meeting the measurement requirements of different height ranges. Whether it is a petite child or a tall adult, both can obtain accurate height measurement results in this adjustable measurement structure.

[0039] When it is necessary to switch to the forward flexion test mode, the measuring plate 301 must be swung first. In the engaging mechanism 8 in the square slot 16, the rotating plate 805 on the bottom plate 801 is connected to the annular clamping member 804. Under the elastic force of the spring 802, the annular clamping member 804 is tightly engaged with the arc-shaped clamping block 302 of the measuring plate 301, forming a stable connection structure, ensuring the stability of the measuring plate 301 in a vertical state. When the swinging operation is performed, the measuring plate 301 will apply a certain external force to overcome the elastic force of the spring 802, so that the annular clamping member 804 gradually loosens the arc-shaped clamping block 302, so that the connector 14 originally connected to the engaging mechanism 8 in the square slot 16 can be smoothly detached.

[0040] Next, the connector 14 on the measuring plate 301 is precisely engaged with the engaging mechanism 8 in the square slot 12 to achieve stable fixation of the measuring plate 301 in the horizontal direction, and the body flexion test mode is successfully switched. At this time, the push plate 309 starts to move under the drive of the slider 308 on the slide rail 307, and the infrared sensor 3010 carefully installed on the inner side of the push plate 309 starts to work immediately. It determines the displacement by emitting infrared rays of a specific frequency and detecting the slight changes in the infrared ray blocking in real time. When the tester performs the body flexion movement, the push of the body will cause the push plate 309 to displace, and the propagation path of the infrared ray will be changed. The infrared sensor 3010 keenly captures this change and converts it into an electrical signal, and then accurately obtains the measurement data of the body flexion according to the preset conversion algorithm of the electrical signal and the displacement.

[0041] The tester is also equipped with some auxiliary structures and components to improve its overall practicality and convenience. The pull plate 403 can be flexibly rotated through the rotating shaft 401. When in the storage state, the clamping rod 904 is tightly engaged and fixed with the cylindrical hole 404 of the pull plate 403 under the elastic force of the second spring 903, ensuring that the pull plate 403 will not shake or unfold at will, and maintaining the overall compactness of the tester. When it is necessary to use the storage pad mechanism 4, it is only necessary to overcome the elastic force of the second spring 903 and pull the slide plate 905 to make the clamping rod 904 disengage from the cylindrical hole 404, and then the rotating shaft 401 can be easily rotated to drive the pull plate 403 to unfold or store, meeting the needs of different usage scenarios, and is mainly used when bending forward.

[0042] In the whole measurement process, the terminal 503 plays a vital role. Through reliable connection with the connectors 14 at different positions, it can timely receive and process the data collected by the ultrasonic sensor 305 during height measurement and the data generated by the infrared sensor 3010 during forward flexion measurement. The terminal 503 can quickly analyze, integrate and store the data, and can also convert the measurement data into information with practical teaching guidance significance according to the preset physical education evaluation standards, such as comparing and analyzing the height data with the average height of the same age group and the same gender group, converting the forward flexion data into corresponding scores, body flexibility levels, etc., and displaying them on the display screen in the form of intuitive charts, texts, etc., so that physical education teachers or testers can clearly understand the measurement results and related analysis;

[0043] In terms of mobility, the universal wheel 7 installed at the bottom of the mounting plate 6 plays a key role. When the universal wheel 7 moves the tester, the universal wheel 7 can turn flexibly, and the tester can be moved smoothly regardless of the flat gymnasium floor or the slightly undulating playground track and other different venue surfaces, thereby improving the portability of the tester between different teaching venues;

[0044] At the same time, the design of the telescopic rod 15 further enhances the convenience of carrying the tester. When the tester needs to be carried over a long distance, the user can easily pull out the telescopic rod 15, and its length can be flexibly adjusted according to the user's height and personal operating habits. The user holds the telescopic rod 15 and cleverly uses the lever principle to pull the entire tester with less force, which is convenient for quickly transferring equipment between different venues on campus, saving manpower and time costs;

[0045] In addition, the weight scale 13 uses high-precision pressure sensor technology. When the tester stands on the weight scale 13, the weight of the body will generate pressure on the surface of the weight scale 13. The changes of these electrical parameters are accurately measured through the internal precision measurement circuit, and after complex calculations and conversions, the body weight data is finally accurately measured, and the data is transmitted to the terminal 503 for recording and further analysis and processing, which provides important data support for comprehensive evaluation of the tester's physical condition.

[0046] Finally, the base 17 located at the four corners of the bottom of the connecting plate 1 provides a stable and reliable support foundation for the entire tester, with a large contact area and sufficient weight. When the tester is placed on the ground for measurement operations, the base 17 can evenly disperse the overall weight of the equipment, effectively reducing the pressure of the equipment on the ground, thereby ensuring that the tester is always placed stably on the ground during the measurement process. Even if the ground is uneven to a certain extent, or the tester has slight movements during the measurement process, the tester will not shake or deviate, etc., creating a stable and reliable basic environment for accurately measuring data such as height, forward bend and weight, effectively guaranteeing the accuracy and reliability of the measurement data, so that the comprehensive physical education tester can exert its maximum efficiency in physical education teaching practice.
