[0043] A method for using an intelligent physical education tester for physical education teaching comprises the following steps:

[0044] S1. First, the tester can stand on the positioning pad 23 and hold the sliding handle 13 with both hands to maintain stability. Then the supervisor can start the drive motor 31 to drive the worm 29 and worm wheel 18 to rotate, so that the first connecting rope 17 can pull the positioning pad 23 upward with the guide wheel 25 as the base point;

[0045] S2. Then, the support frame 21 is slidably connected to the guide rod 32, so that the support frame 21 can be moved upward in a straight line. At the same time, the test person can be transported upward until the test person's arm can touch the round rod 9. The test person can wear the chest strap 3 on the body surface, and then the test person can grasp the round rod 9 with his hand;

[0046] S3. Finally, the supervisor can start the drive motor 31 again to drive the worm 29 and the worm wheel 18 to rotate in the opposite direction, so that the first connecting rope 17 can release the support base 21 to move downward, so that the positioning pad 23 can be disengaged from the tester's feet, so that the tester can hold the round rod 9 to perform a pull-up physical fitness test. At the same time, every time the tester's head is aligned with the sensing probe 6, a count can be performed to facilitate recording the tester's test data.

[0047] The working principle of embodiment 1 is as follows: when in use, the student moves to the positioning pad 23 until his foot steps on the positioning pad 23. Then, the referee can start the drive motor 31 to drive the worm 29 to rotate. When the worm 29 rotates, the worm gear 18 can be driven to rotate at the same time, so that when the worm gear 18 rotates, it can drive the winding rod 22 to rotate, so that the first connecting rope 17 can use the wire wheel 25 as the base point to pull the support base 21 upward. When the student stands on the positioning pad 23, the support base 21 can be lifted up while driving the positioning pad 23 to be lifted, so that the student can be carried upward. At the same time, a plastic gasket is fixedly installed on the top of the positioning pad 23 to prevent the student's feet from slipping, and the student The student can hold the sliding handle 13 with both hands, thereby improving the student's standing stability on the positioning pad 23. At the same time, the sliding handle 13 is slidably connected to the outer ring of the vertical rod 15 to avoid friction between the hand and the vertical rod 15. The support base 21 is slidably connected to the outer ring of the guide rod 32 to ensure that the support base 21 and the positioning pad 23 move up and down in a straight line. When the student moves upward until the hand moves to align with the round rod 9, the drive motor 31 can be stopped. The self-locking property between the worm gear 18 and the worm 29 can prevent the positioning pad 23 from sliding downward, thereby supporting the student to perform preparation work at a specified height. Afterwards, the student can process the chest strap 3 and wear it on the body surface, and then adjust the chest strap 3. The buckle is locked, so that the chest strap 3 can be worn on the student's chest and shoulders. Then, the student can hold the round rod 9. After confirming that the preparation is complete, the referee can start the drive motor 31 again to drive the worm 29 to rotate in the opposite direction, so that the worm gear 18 can drive the winding rod 22 to rotate in the opposite direction, thereby releasing the first connecting rope 17. At this time, the positioning pad 23 will slide downward and reset, so that the positioning pad 23 can be out of contact with the student's feet. At this time, the student can hold the round rod 9 and maintain a suspended posture to perform a pull-up test. There is an electronic signal connection between the induction probe 6 and the external display terminal, so that when the student's head is parallel to the induction probe 6, a signal can be sent to the display terminal to record the student's test data. Then, when the student appears When the student is exhausted, the driving motor 31 can be turned on again, so that the above steps can be repeated to lift the positioning pad 23 again until the positioning pad 23 contacts the student's feet, so as to prevent the student from falling directly downwards and facilitate the student to move smoothly to the ground. When the device is in use, when the student is exhausted and the referee has no time to react, the student's hands will be out of contact with the round rod 9. At this time, by binding the chest belt 3 on the student's body surface, when the student goes down, the connecting rope 2 will be tightened, thereby preventing the student from falling directly to the ground. Moreover, by slackening the connecting rope 2 when the student is in the pull-up posture, it is convenient for the student to perform pull-ups. When the student falls, the connecting rope 2 is tightened to prevent the student from falling. When the device is in use,By turning on the drive motor 31 to drive the worm 29 and worm wheel 18 to rotate forward and reverse, the first connecting rope 17 can pull the support frame 21 upward or downward, thereby carrying the student to a higher position or a lower position smoothly. At the same time, by wearing the chest strap 3 on the student's body, the setting of the connecting rope 2 can prevent the student from falling when exhausted. In addition, the setting of the sensor probe 6 can automatically record the student's test data, thereby realizing intelligent data recording and completing the student's pull-up physical fitness test.

[0048] Example 2

[0049] On the basis of Example 1, Figure 8 As shown, a sealing plug 32 is fixedly connected to the top of the second transfer box structure 2.

[0050] When implementing this embodiment, when dust and impurities accumulate on the front surface of the sensing probe 6, the second connecting rope 37 can be pulled downward, thereby driving the scraper 35 to move downward, and the card key at the rear end of the scraper 35 slides in the card groove inside the front end of the extended rear frame 36, so that the scraper 35 can be ensured to move up and down in a straight line. When the scraper 35 passes the front end of the sensing probe 6, the sponge sheet at the rear end of the scraper 35 can scrape off the dust attached to the front end of the sensing probe 6, so as to achieve the purpose of cleaning the surface of the sensing probe 6. Subsequently, the second connecting rope 37 can be released, and the elasticity of the reset spring 34 will drive the scraper 35 to move upward and reset. When the scraper 35 moves upward and resets, it can be located above the sensing probe 6, so that the scraper 35 can be prevented from affecting the sensing probe 6 and the work is completed.

[0051] 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.

At the same time, the test person can be transported upward until the test person's arm can contact the round rod (9). The test person can wear the restraint chest belt (3) on the body surface, and then the test person can grasp the round rod (9) with his hand; S3. Finally, the supervisor can restart the drive motor (31) to drive the worm (29) and the worm wheel (18) to rotate in the opposite direction, so that the first connecting rope (17) can release the supporting base (21) to move downward, so that the positioning pad (23) can be disengaged from the tester's feet, so that the tester can hold the round rod (9) and perform the pull-up physical fitness test. At the same time, each time the tester's head is aligned with the sensing probe (6), a count can be performed to facilitate recording the test data of the tester.
