Description
Technical field
This utility model relates to a kind of sports equipment, is specifically related to a kind of Automatic-reset tester of body procurvation in sitting posture.
Background technology
Sitting body anteflexion tester is " country's student physical health standard " primary school, junior middle school, senior middle school and the selective-test item of university, the purpose of test is to measure the movable amplitude that the joints such as student's trunk, waist and hip under static state are likely to be breached, these joints, position of dominant response, ligament and the extensibility of muscle and elasticity, and the level of development of student's health pliability quality.When pliability refers to human body execution, the expansion service of joint, muscle, tendon and ligament.The quality of flexibility quality, depends on the anatomical structure in joint and the volume size of periarticular soft tissues and the extensibility of ligament, tendon, muscle and skin.The motility in joint can be improved by physical training, improve function and muscle, ligament, the extensibility of tendon of periarticular soft tissues.
Sitting body anteflexion tester includes base plate, pedal, support and the pushing board being slidably connected on support, is placed on by instrument on smooth ground, before test, being corrected, experimenter is sitting on base plate, and two lower limbs stretch, inflexibility, heels together, separately about 10 ~ 15 centimetres of tiptoe, step on the footrests, folding the arms, two-arm and hands stretch, and gradually make high low hand, promote pushing board advancing slip gently with finger tip in two handss, during until extension can not be continued.But in daily workout or test, often occurring that experimenter's arm is had an effect suddenly, pushing board, after departing from human hand, continues advancing slip under effect of inertia, causes measurement result inaccurate；And, after everyone test terminates, need manually pushing board to be repositioned to initial position, troublesome poeration, affect efficiency.Just like the automatic reposition-type sitting body anteflexion tester patent of Application No. 201220023448.1 disclosed in prior art, although being capable of the self-return after test, but in test process, affected by return spring and sawtooth, the resistance promoting push pedal is increased, it is difficult to reach the practical level of experimenter after certainty.
Utility model content
This utility model needs manually to be repositioned to by pushing board the defect of initial bit to overcome existing sitting body anteflexion tester, it is provided that a kind of Automatic-reset tester of body procurvation in sitting posture.
The technical scheme that this utility model is used by solving the problems referred to above is: a kind of Automatic-reset tester of body procurvation in sitting posture, including pedestal, pedal and set graduated scale bar, scale bar and pedestal are parallel to each other and the most at a certain distance, pedal is vertically connected between scale bar and pedestal, pushing board it is slidably connected with on scale bar, it is characterized in that: the rear end of described pedestal is vertically provided with riser, the facade of riser is provided with single-acting spring reset cylinder and controller；The front end of pedestal extends connection base, base is provided with electron pressure switch, when experimenter is positioned on base, the switch contacts of electron pressure switch is connected and outputs signal to controller, controller controls the piston rod of single-acting spring reset cylinder and stretches out, and pushing board is pushed to its initial position being positioned at scale bar front end；When experimenter leaves base, the switch contacts of electron pressure switch disconnects, and single-acting spring reset cylinder automatically resets under the effect of self spring, and wherein, pedal is provided with the breach passed through for single-acting spring reset cylinder and pushing board.
Further, scale bar and pushing board are nonmagnetic material, and the bottom of two facades being oppositely arranged is equipped with capacitive induction soft-touch control on pushing board, one of them facade of pushing board is provided with magnetic limited block, electric magnet and commutator, capacitive induction soft-touch control, commutator, electric magnet constitutes the circuit of conducting with external power supply, in the circuit, two capacitive induction soft-touch controls are arranged in parallel, magnetic limited block is connected on electric magnet by compression spring, when the capacitive induction soft-touch control touched on pushing board, this circuit turn-on, magnetic limited block adsorbs on electric magnet, when departing from the capacitive induction soft-touch control on pushing board, this circuit disconnects, magnetic limited block is pressed on scale bar under the effect of compression spring.
Further, the side of pushing board is provided with extension board, and electric magnet is fixed on this extension board.
In this utility model, for increasing the dependability of this device, the front-end and back-end of scale bar are correspondingly provided with front apron and backboard respectively.
For increasing the comfortableness of this device, described pedestal is provided with cushion.
In this utility model, electron pressure switch, single-acting spring reset cylinder and capacitive induction soft-touch control are existing known parts.Electric magnet includes Magnet and the coil being located on Magnet, the two ends of coil are connected with commutator by wire respectively, i.e. electric magnet is turned on external power supply by commutator, magnetic limited block is attracting with electric magnet magnetic, when the finger of experimenter or the piston rod of single-acting spring reset cylinder contact with the capacitive induction soft-touch control on pushing board, circuit turn-on, pass through commutator, the alternating current of external power supply is converted into unidirectional current, by galvanic current, electric magnet is powered, electric magnet is made to produce stable magnetic field, thus magnetic limited block is produced reliable and stable magnetic effect.
Beneficial effect: 1, this utility model is according to the feature of single-acting spring reset cylinder: during energising, cylinder one end supply compressed air-driven piston rod stretches out, and after power-off, cylinder automatically resets under the effect of self spring.For ensureing the accuracy of test, experimenter's general light foot is tested, after test terminates, experimenter is sitting in wear shoes on base, electron pressure switch on base is under experimenter's pressure, and its switch contacts closes, and provides signal to controller, controller controls the piston rod of cylinder and stretches out, and promotes pushing board to slide into the initial position of scale bar；After experimenter leaves base, the switch contacts of the electron pressure switch on base disconnects, and cylinder automatically resets under the effect of self spring.
2, when experimenter is flat be sitting on pedestal start to test time, two hand fingers promote pushing board advancing slip, after the pressure of finger experienced by the capacitive induction soft-touch control on pushing board, and circuit turn-on, magnetic limited block adsorbs on electric magnet, and pushing board can on scale bar slidably；When finger departs from pushing board, circuit disconnects, and magnetic limited block is pressed on scale bar under compression spring effect, and pushing board will not continue advancing slip under the effect of inertia of thrust, it is ensured that the accuracy of test.In like manner, when single-acting spring reset cylinder promotes pushing board to reset, the capacitive induction soft-touch control on pushing board is experienced the pressure of piston rod, is repeated above magnetic or disengaging process.
