Description

Physique tester

Technical Field

The invention relates to the field of detection equipment, in particular to a physique tester.

Background

The forward bending of the sitting position is a physical health test project of the colleges, the middle and the schools, and the test aim is to measure the possible activity range of joints such as the trunk, the waist, the hip and the like in a static state and mainly reflect the extensibility and elasticity of the joints, ligaments and muscles of the parts and the development level of the body flexibility.

In the past, when students are investigated on physical health, the flexibility is generally tested by adopting a standing body forward bending method. When the standing body forward bending test is carried out, a test subject stands on a test bench which is at least 40 cm away from the ground, and multiple factors such as fear and subconscious self-protection limit the exertion of the capability of the test subject. When the human body is in a posture with the knee joints straightened to 180 degrees and the body trunk bent forward to 180 degrees, the muscles of the lower legs, the thighs and the rear group of the trunk are kept at certain tension to keep the center of gravity of the body in the supporting surfaces of the two feet, so that the forward extension range of the arms and the trunk is limited. Developed countries commonly employ anteflexion of the sitting body to assess flexibility.

When in testing, the method generally comprises the following steps:

1. the subject sits on the pad, with the legs straightened out and not bent, the heels closed, the toes separated by about 10-15 cm, steps on the vertical plate of the meter, and closes the hands.

2. The two arms and the hand are straightened out, the upper body is gradually bent forwards, and the middle finger tips of the two hands are used for slightly pushing the vernier on the scale to slide forwards until the vernier cannot be extended forwards continuously.

During testing, two contraindications are generally required, namely, the legs cannot be bent in the measuring process and need to be kept in a straight state; and secondly, when the push plate is pushed by two hands, force cannot be suddenly exerted, and the push plate needs to keep going forward at a constant speed.

The push plate of the existing testing device is arranged on the vernier in a sliding mode, the hand pushing speed is not controllable, and when a tester suddenly exerts force, the push plate can continuously move forward for a certain distance due to the fact that inertia acts on the push plate after being separated from the hand, and testing is not accurate enough.

Example two:

as the testee may bend the leg involuntarily to cause data inaccuracy in order to obtain better performance during the testing process, on the basis of the first embodiment, as shown in fig. 1 and fig. 2, the present embodiment further includes a leg pressing device, which includes a pressing plate 50, a rotating handle 51, a second pawl 55 and a stop block 57, the stop block 57 is fixedly disposed on the seat cushion 10, a stop tooth 58 is disposed on the stop block 57, the rotating handle 51 is rotatably disposed on the seat cushion 10, the rotating handle 51 is arc-shaped and extends towards the side away from the mounting plate 20, the pressing plate 50 is fixedly disposed on the rotating handle 51, in the present embodiment, there are two sets of leg pressing devices, wherein there is one pressing plate 50, and two ends of the pressing plate 50 are respectively fixedly disposed at the upper ends of the two rotating handles 51 for pressing the leg; a second pawl 55 is hinged to the stem 51, the second pawl 55 cooperating with the stop tooth 58, the second pawl 55 serving to prevent the pressure plate 50 from moving away from the seat cushion 10.

During testing, after the leg of the tested person is flatly placed, the rotating handle 51 is rotated to enable the pressing plate 50 to be pressed on the lower leg, the second pawl 55 abuts between the stopping teeth 58, if the lower leg of the tested person is bent, the pressing plate 50 can be abutted, the rotating handle 51 is driven to rotate, when the rotating handle 51 rotates, the second pawl 55 can rotate, and the second pawl 55 abuts between the stopping teeth 58 at the moment and cannot rotate, so that the lower leg can be pressed. After the test is completed, the second pawl 55 is simply pulled upward.

Further, as shown in fig. 2, in order to facilitate lifting of the second pawl 55, the leg pressing device further includes a supporting block 52, a second pulling bolt 53 and a second tension spring 54, the supporting block 52 is fixedly disposed on the rotating handle 51, the second pulling bolt 53 is slidably disposed on the supporting block 52 up and down, the second tension spring 54 is fixedly disposed between the supporting block 52 and the second pulling bolt 53, and the second pawl 55 is hinged to the second pulling bolt 53. After the test is finished, the second pulling bolt 53 is pulled upwards to drive the second pawl 55 to move upwards, so that the second pawl 55 is separated from the stopping tooth 58, the rotating handle 51 can be rotated, and the testee can stand up.

Since the position of the lower leg is different due to different bodies of different testees, and therefore the position of the pressure plate 50 needs to be adjusted, the present embodiment further includes a second slide 56, as shown in fig. 1, the second slide 56 is slidably disposed on the seat cushion 10, and the stop block 57 is fixedly disposed on the second slide.
