The use method and the advantages of the invention are as follows: when the sitting position body forward bending movement device convenient for physical fitness test is used, the sitting position body forward bending movement device comprises the following steps:
the method comprises the following steps: as shown in figures 1 and 2, a testee or a trainer adopts a sitting position, two feet are attached to a reference plate 2, the knee joint is kept straight, the height of a vernier scale 9 is adjusted by a height adjusting mechanism according to the testee or the trainer, the adjustment operation is as follows, a rotary turntable 8 synchronously drives a worm 5 to rotate through a shaft rod, the rotation of the worm 5 drives a turbine 6 to rotate anticlockwise or clockwise, so as to synchronously drive a mandril 7 to rotate anticlockwise or clockwise, the anticlockwise or clockwise rotation of the mandril 7 enables the upper end of the mandril 7 to be lifted or lowered in the vertical direction, and simultaneously drives a slide block 26 to move leftwards or rightwards on a slide rail 10, the lifting or lowering of the upper end of the mandril 7 synchronously drives the vernier scale 9 to be lifted or lowered, so as to be suitable for the testees or the trainees with different lifts, and simultaneously drives a slide rod 4 to slide upwards and downwards in a guide sleeve 3 when the vernier scale 9 is lifted or lowered, the horizontal position of the vernier 9 is kept unchanged during height adjustment, the ejector rod 7 and the sliding block 26 support the vernier 9, and the vernier 9 is kept stable by utilizing the self-locking characteristic between the turbine 6 and the worm 5;
step two: as shown in fig. 1, 3, 4 and 5, during testing, in an initial state, the push plate 11 is located at the leftmost end of the vernier scale 9, as shown in fig. 3, the cylinder 18 pushes the friction plate 19 to be close to but not in contact with the first pulley 14, and the rocker 20 is in a state of being inclined to the lower left, so that the press plate 21 is in pressing contact with the belt 16, and a testee or a trainer pushes the push plate 11 forward with a finger, so that the push plate 11 moves rightward along the vernier scale 9, and at the same time, the first spring 13 obtains a leftward restoring force, the push plate 11 moves rightward and simultaneously drives the belt 16 to move clockwise, so as to drive the first pulley 14 and the second pulley 15 to rotate clockwise, if the push plate 11 is pushed at an excessively high speed, the first pulley 14 and the second pulley 15 are driven to rotate excessively fast by the belt 16, as shown in fig. 5, at this time, the counterweight 24 in the groove 23 under the action of the centrifugal force slides, the belt wheel I14 is limited in rotation speed by the aid of the belt 16, so that the push plate 11 is limited in movement speed, and inaccurate measuring results caused by inertia force due to too fast movement of the push plate 11 are avoided;
when the first belt wheel 14 rotates slowly and returns to normal speed, the centrifugal force is reduced, the second spring 25 returns under the action of the restoring force of the second spring 25, the degree of abutting contact with the friction plate 19 is reduced to be non-contact, so that the limitation on the first belt wheel 14 is removed, automatic speed limiting is realized, and the structure is simple;
after the first spring 13 is compressed, the leftward restoring force of the first spring enables the push plate 11 to be subjected to leftward thrust when the push plate is at the stop position, and then the push plate has a tendency of driving the belt 16 to run anticlockwise, so that the pressing block 21 is pressed against the belt 16 and generates pressing force, and then rightward friction force is generated, so that the pressing block 21 drives the rocker 20 to have a tendency of rotating anticlockwise, and further the rocker 20 drives the pressing block 21 to move up and down in the vertical direction, the pressing force on the belt 16 is increased, the belt 16 cannot run, and therefore the push plate 11 is kept at the stop position and is not influenced by the restoring force of the first spring 13, test data can be read conveniently, and misreading is prevented;
after the test is finished, as shown in fig. 4, the cylinder 18 is started to enable the piston rod to drive the friction plate 19 to move right to be far away from the first belt wheel 14, and meanwhile, the rocker 20 is driven to rotate clockwise through the third spring 22, so that the pressing block 21 is separated from the belt 16, no force is applied to the belt 16 at the moment, the pushing plate 11 is pushed to move left rapidly under the action of the leftward restoring force of the first spring 13 to reset, so that the next person to be tested or a trainer uses the pushing plate, at the moment, the balancing weight 23 in the groove 23 cannot be in contact with the friction plate 19 under the action of centrifugal force due to the fact that the friction plate 19 is far away, the pushing plate 11 is.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
