technical field

The invention provides a sitting and swivel measuring instrument, which belongs to the field of physical training and health detection.

Background technique

In the process of selection and training, athletes need to understand the flexibility of the athlete's body. Among them, the range of trunk rotation is an important index to measure flexibility. The range of torso rotation also needs to be known in rehabilitation and rehabilitation training. Under the existing conditions, the range of torso rotation can only be estimated by visual inspection, and the exact angle of torso rotation cannot be given, which has a great impact on the further development of scientific training plans. As shown in Figure 4, the measurement of the torso rotation is performed by means of the arm pinch rotation method. The specific measurement method is: on a flat ground, draw a circle with a diameter of 1.5m marked with an angle scale (0°～180°, the minimum scale is 5°), the center of the circle and the diameter. The subject stands upright naturally, with feet shoulder-width apart, standing in the center of the circle, with the vertical axis of the body located at the center of the circle, and a wooden stick with a diameter of 2 to 2.5 cm is clamped behind the body with the bend of the elbows, and the lengths of both ends are the same , keep the wooden stick parallel to the ground, and try to rotate the body around the vertical axis as much as possible. Measure the angle at which the pinch roll turns. The subject to be measured stands with his feet about 30cm apart, stands on a straight line from 0° to 180°, bends his elbows behind his body, and clamps a wooden stick with a tapered weight, so that the tip of the cone is facing 0°, and slowly turns to the left and right. body, the measured value is the angle of torso rotation ^[2,6] . This measurement method cannot meet the measurement accuracy. In order to solve the above problems, our team developed a new type of measuring instrument.

The specific embodiment: the present invention will be further described below in conjunction with accompanying drawing:

As shown in Fig. 1, the present invention provides a kind of seat swivel measuring instrument, and this measuring instrument comprises base 1, leg fixing mechanism 2, seat 3, main elevating mechanism 4, circular guide rail 5 and double shoulder pad mechanism 6; The internal fixing mechanism 2, the seat 3, and the main lifting mechanism 4 are all directly connected to the base, the circular guide rail 5 is installed on the main lifting mechanism 4, the double shoulder pad mechanism 6 is arranged on the circular guide rail 5, and the seat 3 is arranged on the main lifting mechanism. Between mechanism 4 and leg fixing mechanism 2. The dimensions between the various parts are designed according to ergonomic requirements, and can be adjusted within a limited range to meet the requirements of testers of different body shapes and heights.

The leg fixing mechanism 2 is composed of a lifting mechanism, a pedal, a front and rear adjustment mechanism, a clamping pad and a clamping pad self-locking mechanism. The pedal is fixedly arranged at the lower part of the lifting mechanism, and the clamping pad is arranged at the upper part of the lifting mechanism and can be driven up and down by the lifting mechanism. Moving, the lifting mechanism is set on the base 1 through the front and rear adjustment mechanism and can move back and forth relative to the seat 3 under the action of the front and rear adjustment mechanism; the clamp pad self-locking mechanism is arranged on the clamp pad.

Both the front and rear adjustment mechanism and the pad self-locking mechanism are realized by the screw nut mechanism.

The seat 3 adopts a fixed type, and the shape of the cushion is designed according to the curve shape of people's buttocks to ensure that the tester is comfortable during the test. The seat height is determined according to the higher value of the calf length of the person, so that by adjusting the height of the pedals, it can be applied to other people.

During the test, the tester puts his feet on the pedals, and the height of the pedals is adjusted by the lifting mechanism to adapt to the length of the lower legs of different testers. The front and rear positions of the pedals can be adjusted through the longitudinal adjustment mechanism to meet different thigh lengths. After sitting on the seat, the tester feels comfortable. After the above adjustments, adjust the self-locking mechanism of the clamping pads so that the two sets of clamping pads clamp the tester's knee joint and lower leg respectively, so that they cannot move freely, so as to ensure the accuracy of the test results.

The main lifting mechanism adopts the screw nut mechanism and is manually adjusted. Generally, the height of the circular guide rail and the double shoulder pad mechanism is adjusted according to the height of the tester before the test. After the adjustment is completed, the main lifting mechanism should be locked to avoid movement of the main lifting mechanism during the test and affect the test accuracy. The circular guide rail 5 is a C-shaped structure, the circular guide rail lower plate is connected firmly with the main lifting mechanism, and the circular guide rail upper plate is connected firmly with the double shoulder pad mechanism. The circular guide rail is used to realize that the double shoulder pad mechanism rotates with the tester's shoulders and displays the rotation angle.

The double shoulder pad mechanism 6 is made up of a double hub shoulder pad mechanism and a pad, and the double shoulder pad mechanism is arranged on the circular guide rail 5 through a lateral adjustment mechanism. The horizontal adjustment mechanism of the double shoulder pad mechanism adjusts the distance between the two shoulder pads through the screw nut mechanism, so as to adapt to testers with different shoulder widths and ensure the comfort when the shoulder pads are connected to the tester's shoulders.

The adjustment of the tester is all manually adjusted, which makes the overall structure of the tester simple, easy to maintain, and has no special requirements for the test environment.

The lower plate of the circular guide rail 5 is connected with the main elevating mechanism, and the upper plate of the circular guide rail 5 is connected with the double shoulder pad mechanism, and the double shoulder pad mechanism 6 is also provided with a reset mechanism that helps the double shoulder pad mechanism 6 to reset.

The upper plate of the arc guide rail is provided with a stop pin which moves together with the double shoulder pad mechanism 6, and the stop pin is linked with the sliding mark on the lower plate of the arc guide rail, and a scale is arranged on the lower plate of the arc guide rail.

The circular guide rail is used to realize that the double shoulder pad mechanism rotates with the tester's shoulders and displays the rotation angle. When the tester twists to the left and right sides, the angle of the tester's twist to the left and right sides can be read from the circular guide rail respectively, and the twist angle to each direction is the test result. In addition, the mechanism also has a reset function to ensure that the tester returns to the initial state after the test is completed.

The double shoulder pad mechanism consists of a double hinge shoulder pad mechanism and a pad. During the test, the double-hinge shoulder pad mechanism is in contact with the tester's front chest, the pad is in contact with the tester's back shoulder, and the front and back clamp the tester's shoulder to form a whole. The horizontal adjustment mechanism of the double shoulder pad mechanism adjusts the distance between the two shoulder pads through the screw nut mechanism to adapt to testers with different shoulder widths and ensure comfort when the shoulder pads are connected to the tester's shoulders. The shoulder pad can turn around the screw shaft, and stay at any position under the action of the pressure spring, so as to adapt to human chests of various thicknesses.

As shown in Figure 2, the application process of the present invention is as follows: during the test, the tester requires to sit on the measuring seat 3 with a basic sitting posture, the upper body is naturally straight, the abdomen is retracted, the double-hinge shoulder pads and the pads are used to fix the shoulders together, Hold the double-hinge shoulder pads with both hands, bring the lower limbs together and shoulder-width apart, bend at 90 degrees, and put your feet on the pedals. The height of the pedal is adjusted by the lifting mechanism to adapt to the length of the calves of different testers. The front and rear positions of the pedal can be adjusted through the front and rear adjustment mechanism to meet different thigh lengths. The adjustment is carried out after the tester sits on the seat, and the tester feels comfortable. allow.

When the tester is not ready to measure, the arc guide rail and the slider are in a self-locking state, and there is no relative sliding. When the preparation is ready for measurement, the stop pin is lifted and rotated by a third person to change to the test direction. At this time, the shoulders of the tester drive the entire double shoulder pad mechanism 6 to rotate, so that the arc guide rail and the slider slide relative to each other. The stop pin on the upper plate of the arc guide rail drives the slider to slide on the lower plate of the arc guide rail, that is, the rotation angle of the spine is reflected in the relative sliding angle between the arc guide rail and the slider, and displayed on the scale on the lower plate of the arc guide rail . After the test is over, the entire double shoulder pad mechanism 6 can automatically return to the initial test state, ready to measure alternately on the left and right sides or measure the next tester. The whole test process is simple and easy, and the angle value of spinal gyration can be measured in a short time, so as to accurately know the flexibility of the spine.
