Two reset frames are arranged facing each other, a moving shaft is slidably arranged on the positioning frame, the main shaft, fixed shaft and moving shaft are arranged in sequence from the opening to the support seat, two rotating frames are arranged on the moving shaft and two Two rotating frames are arranged facing each other, the rotating frame is hinged with the reset frame, a reset rope is arranged on the moving shaft, the free end of the reset rope passes through the support seat and the positioning frame and extends away from the positioning frame, when the The moving shaft moves in a direction close to the support seat, and drives the two reset frames and the two rotating frames to move closer to each other, and the reset frames can be in contact with the plectrum. When the moving axis moves close to the support seat, it drives the two reset frames and the two rotating frames to move closer to each other. The reset frame can be in contact with the paddle, supports left and right hand touch, two-way movement, and can quickly move the paddle. reset.

The data collection of height touching devices on the market is mainly collected by human eyes. If the electronic sensor is used to detect the displacement of the paddle to collect the height touching data, the data collection will be faster than human eye observation. However, there are mainly two types of distribution of the paddles on the market: the first type is that the paddles are stacked and placed in contact with each other; the second type is that each paddle is kept at a predetermined distance, and the distance is extremely small. The above two assembly situations, no matter which one is suitable without exception, when the student's fingers can touch the highest-level plectrum and drive the plectrum to deflect, one or more plectrums on the upper floor will be affected by fluctuations. A certain angle of deflection occurs, so it is difficult to use electronic sensors to collect data on the paddle swing, and if you touch the sensor or pressure sensor on the paddle, this will increase the purchase cost of the entire touch height device; or To solve this problem by setting the fuzzy value through the program, it is obviously unrealistic to predict the deflection angle of the pick due to the magnitude of the force generated by the slapped pick and the fluctuation of the slap.

As shown in Figures 1-9, a physical health test data collection device includes a positioning frame, a shaft 100 is installed on the positioning frame, and a plurality of paddles 101 are rotated on the shaft 100, and the paddles 101 are respectively set There is a concave groove and a guide slope 2, and a swing arm 11 is arranged in the concave groove, wherein:

The swing arm 11 on the plectrum 101 of the next layer abuts on the guide slope 2 of the plectrum 101 of the previous layer, and the guide slope 2 is provided with a protrusion;

When the driving force received by the plectrum 101 is greater than the preset value, it drives the swing arm 11 to cross the protrusion; when the driving force received by the plectrum 101 is less than the preset value, it drives the swing arm 11 and cannot cross the protrusion. and reset.

Specifically, in the embodiment, a plurality of paddles 101 are serially sleeved on the shaft 100 and rotate around the shaft 100 as the axis. In actual operation, by adjusting the height of the bracket to reach a suitable height, while keeping the plectrum 101 and the base of the bracket on the same horizontal line (subject to the state shown in Figure 1), the students jump up and beat the plectrum 101, and are subject to The plectrum 101 that beats can be deflected by being beaten. The plectrum 101 that has not been tapped will remain in the initial position (state shown in FIG. 1 ) because of the abutment of the swing arm 11 .

Further, in the embodiment, the top of each plectrum 101 is provided with a concave groove, and the bottom is provided with symmetrically distributed guide slopes 2. The guide slopes 2 have a double-peak structure. In the initial position, the swing arm 11 is located at the double-peak position. depressions between structures. And the plectrum 101 that is positioned at the top layer, the swing arm 11 on it abuts on the guide slope 2 on the top of the positioning frame (as shown in FIG. 9 ), so that each plectrum 101 will obtain the abutment brought by the swing arm 11. coming damping force. Furthermore, the swing arm 11 in the embodiment can be an elastic plate, which swings up as a whole, and its end abuts on the concave part between the double-peak structures of the guide slope 2; or it is pushed up by the top spring to swing up , the end abuts on the concave portion between the double peak structures of the guide slope 2; or any driving structure known to those skilled in the art to drive the swing arm 11 to swing up.

Furthermore, the driving force received by the plectrum 101 referred to in the embodiment is greater than the preset value, which refers to the force that the student slaps the plectrum 101 on the plectrum 101 during the test; and the plectrum 101 received When the driving force is less than the preset value, it means that during the student's test, the plectrum 101 closest to the slapped plectrum 101 will generate friction or pat the plectrum 101 due to the rotation of the slapped plectrum 101 The force that drives the entire positioning frame or the shaft rod 100 to shake and acts on other unbeaten paddles 101 . In the embodiment, because each layer of plectrums 101 is contacted by the swing arm 11, each plectrum 101 will have a certain damping force, so as to ensure that the plectrums 101 that have not been tapped will not be affected by friction or external force. And deflection occurs, and the plectrum 101 on the top layer abuts on the positioning frame through the swing arm 11, which ensures that all plectrums 101 that are not beaten will not be deflected as a whole due to friction or external force.

It should be noted that the guide slope 2 in the embodiment has a double-peak structure. At the initial position, the swing arm 11 is located in the depression between the double-peak structures. The depression is actually for positioning, mainly for the reset of the plectrum 101. Or when the driving force received by the plectrum 101 is less than the preset value, it drives the swing arm 11 and cannot go over the protrusion and reset. In both cases, it can completely return to the initial position, and no manual alignment operation is required.

In the above-mentioned embodiment, when the multiple plectrums 101 stacked and distributed on the shaft 100 are kept in the original state, the swing arm 11 on the plectrum 101 swings up and abuts against the plectrum 101 of the upper stage, so that multiple plectrums 101 The two plectrums 101 abut each other through the swing arms 11 to form a whole; and when the student pats the plectrum 101, the plectrum 101 is slapped and swings. Under the guidance of the cover 3, one or more paddles 101 of the upper layer are separated from one or more paddles 101 of the upper layer, which makes the one or more paddles 101 of the upper layer that should be subjected to friction or vibration to swing or shake are subjected to the friction force of the paddles 101 of the upper layer. block, return to the original position under the action of the guide slope 2. Thereby avoiding when the student slaps the plectrum 101, one or more plectrums 101 on the upper layer swing or shake due to the disturbance of friction or vibration factors.

As an embodiment further provided by the present invention, a tension spring 12 is provided on the swing arm 11, and the tension spring 12 is used to pull the swing arm 11 so that the upper swing abuts against the guide slope 2; when the driving force received by the plectrum 101 When the value is less than the preset value, the lower swing arm 11 is pulled by the extension spring 12 to return to the initial position by the protruding part and drives the plectrum 101 to reset. Specifically, the swing arm 11 in the embodiment is rotatably set in the concave groove on the pick piece 101, and is pulled by the tension spring 12, so that the swing arm 11 swings up to abut against the guide slope on the pick piece 101. 2, so that the plectrum 101 remains on the initial position. In the course of the test, the student receives the frictional force of the plectrum 101 acting on the upper layer or the force generated by the vibration of the positioning frame or the shaft rod 100 when the plectrum 101 is slapped, and the plectrum 101 will be deflected so that it occurs. Swing left or right, and during the swing process, when the rotational force of the plectrum 101 is not enough to drive the swing arm 11 over the protrusion of the guide slope 2, the tension spring 12 shrinks and pulls to make it swing up, and finally makes it The swing arm 11 stops in the recessed portion, so that the plectrum 101 remains at the initial position.

Further, the pull spring 12 in the embodiment is used to drive the swing arm 11 to swing up to abut against the recessed portion of the guide slope 2. 12 is pulled, and the swing arm 11 slides down along the protruding part and returns to the concave part.

Specifically, in the embodiment, the shaft rod 100 is fixedly provided with guide rings 1 at intervals, and the bottom of the guide ring 1 is provided with a stage 7 . The paddle 101 in the technical solution includes a paddle and a rotating part, and a groove is opened at the bottom of the rotating part, and the carrier 7 is located in the groove and is connected in rotation with the rotating part.

Further, the guide ring sleeve 1 in the embodiment is provided with a guide groove (as shown in FIG. 5 ), and the end of the guide rod 13 on the swing arm 11 is located in the guide groove. In a specific embodiment, the student test jumps up and pats the plectrum 101, and the states of the plectrum 101 are as follows:

The plectrum 101 that is beaten rotates, and the swing arm 11 slides toward the protrusion along the concave portion of the guide slope 2, and the force received by it is greater than the damping force of the swing arm 11 sliding toward the protrusion along the concave portion, so the swing arm 11 crosses over. bulge. And when it has just crossed the protruding part, along with the rotation of the plectrum 101, the guide slide bar 13 slides in the guide slide groove, and at the same time, the swing arm 11 swings down to a certain angle, and is pulled by the tension spring 12 to swing. The hem of arm 11 enters in the sliding recess groove. When the swing arm 11 is pulled by the tension spring 12 and swings down actively, the guide slide bar 13 actively slides along the guide chute, thereby driving the paddle 101 to rotate actively, and stop after rotating to the maximum rotation angle, avoiding tapping the paddle 101, the driving force received by the plectrum 101 is too large, and when it reaches a predetermined angle, the plectrum 101 will receive a reaction force, so that the plectrum 101 rotates in the opposite direction, so as to prevent the plectrum 101 from rebounding and rotating. Occurrence of accidental injury caused by fingers;

The plectrum 101 that has not been patted is due to the force generated by the friction force of the plectrum 101 acting on the upper layer or the vibration positioning frame or the shaft rod 100 due to being patted by the plectrum 101, and the plectrum 101 will be deflected, so that it occurs. Swipe left or right. And in the swinging process, when the rotational force of the plectrum is not enough to drive the swing arm 11 over the protrusion of the guide slope 2, the extension spring 12 shrinks and pulls to swing up, and finally makes the swing arm 11 stop in the concave portion , so that the plectrum 101 remains at the initial position.

As yet another embodiment further provided by the present invention, the pick 101 is provided with a rotating snap ring 4, and the rotating snap ring 4 is provided with an elastic member 5, and the elastic member 5 is used to keep the pick 101 at the original position; When the driving force received by the plectrum 101 is greater than a preset value, it swings to cause the elastic member 5 to deform under force. Specifically, a rotating snap ring 4 is provided in the groove of the rotating part, and the elastic member 5 is an elastic sheet, one end of which is installed in the through groove on the stage 7, and the other end is in contact with the rotating snap ring 4. Under normal conditions, the plectrum 101 remains on the initial position. And the plectrum 101 that is beaten rotates, and the swing arm 11 slides toward the projection along the concave portion of the guide slope 2, and the force it receives is greater than the damping force that the swing arm 11 slides toward the projection along the concave portion, then the swing arm 11 over the bulge. And when it has just crossed the protruding part, along with the rotation of the plectrum 101, the guide slide bar 13 slides in the guide slide groove, and at the same time, the swing arm 11 swings down to a certain angle, and is pulled by the tension spring 12 to swing. The hem of arm 11 enters in the sliding recess groove. When the swing arm 11 is pulled by the tension spring 12 to swing down actively, the guide bar 13 actively slides along the guide groove, thereby driving the plectrum 101 to actively rotate, and after rotating to the maximum rotation angle, the elastic member 5 at this time In the deformed state, the elastic member 5 is released to return to the original state, thereby driving the plectrum 101 to return to the initial position.

As yet another embodiment further provided by the present invention, in the above-mentioned embodiment, the plectrum 101 is instantaneously reset after being tapped, and the instantaneous reset will have the following two problems. The first is elastically reset, and the reset interval is short, which is not conducive to electronic detectors. Response: after the plectrum 101 is deflected to the maximum rotation angle, its instantaneous reset is likely to hurt the student's fingers. For this reason, the present invention provides the following embodiments to solve this problem, that is, a delay mechanism 6 is added, and the delay mechanism 6 includes a ratchet 61 and a power storage disc 62, and a trigger groove 621 is provided on the power storage disc 62; when the power storage disc 62 rotates to The ratchet 61 is provoked by the trigger groove 621 to release the rotating snap ring 4 to reset the plectrum 101 . Specifically, the main function of the delay mechanism 6 in the above-mentioned technical solution is to convert the instantaneous reset of the plectrum 101 into a delayed reset and increase the interval in the middle, which not only ensures the data collection of the electronic detector, but also ensures the driving of the reset mechanism. The reset of paddle 101 will not cause the occurrence of accidental injury time.

Further, one side of the power storage disk 62 in the embodiment is provided with a concave groove, and the torsion spring 622 is installed in the concave groove, and the power storage disk 62 is rotatably arranged on the stage 7, and the power storage disk 62 can follow the rotating snap ring 4 synchronous rotation, which can be through a gear structure; or a pulley transmission mechanism, or a synchronous transmission mechanism known to those skilled in the art. When the rotating clasp 4 rotates, the ratchet 61 does not have the ability to lock, and its rotation will make the ratchet 61 swing (the ratchet 61 is rotatably arranged on the platform 7 ). Furthermore, a raised portion is provided on the top of the power storage plate 62 , and an iron ring is arranged on the raised portion, and one side of the iron ring is concave, that is, the trigger groove 621 .

In a specific embodiment, when the plectrum 101 is tapped to reach the maximum rotation angle, the rotating snap ring 4 is locked by the ratchet 61 . At this time, when the torsion spring 622 on the power storage disc 62 is released and returns to its original state, the power storage disc 62 will rotate. Since the power storage disc 62 is installed through a rotating damping bearing, its rotation rate will remain at a predetermined rate. Therefore, when the power storage disc 62 rotates a predetermined angle, the ratchet 61 will be driven to move to release the rotating snap ring 4 . The deformed elastic member 5 is released to return to the original state, thereby driving the plectrum 101 to return to the initial position.

As an optimal embodiment further provided by the present invention, according to FIG. 6 and FIG. 8 , the delay mechanism 6 includes a single-slot sheave 63, and a locking block is arranged on the rotating snap ring 4, and the rotating snap ring 4 and the power storage disc 62 rotate synchronously. ; When the driving force received by the plectrum 101 is greater than the preset value, the rotating snap ring 4 swings with it, and the block pushes the single-port sheave 63 to rotate a predetermined angle, and the single-port sheave 63 is locked by the pawl 61 . Specifically, in the above-mentioned technical solution, the single-port sheave 63 is rotatably arranged on the carrier platform 7, and the single-port sheave 63 and the power storage disc 62 are connected by a belt, and when the plectrum 101 is slapped and rotated, its Rotate until the guide slide bar 13 is located in the guide slide groove and slide to the swinging angle of the swing arm 11 enough to drive the extension spring 12 to make the swing arm 11 swing down quickly. At this time, the block on the rotating snap ring 4 will be stuck in the single-mouth sheave 63 and drive the single-mouth sheave 63 to rotate, and the synchronous power storage disc 62 will rotate synchronously, so that the torsion spring 622 stores power.

Further, in the above technical solution, according to Fig. 6, a half-tooth ratchet 631 is provided on the single-mouth sheave 63; Len 631 rotates by a predetermined angle. Specifically, in the embodiment, when the half-tooth ratchet 631 rotates with the single-mouth sheave 63, the pawl 61 does not have the ability to lock, and its rotation will make the pawl 61 swing (because the iron ring is an elastic structure, Because when the ratchet 61 swings, it will be reset by the elastic release of the iron ring), thereby locking the single-mouth sheave 63. And when the rotation angle of the plectrum 101 reaches the maximum, under the restriction of the ratchet 61, the single-mouth sheave 63 cannot be moved and rotated by the rotating snap ring 4 . At this time, the power storage plate 62 rotates, and each turn will be moved by the ratchet 61 to release the half-tooth ratchet 631 until the power storage plate 62 rotates a few times, then the ratchet 61 will move to the half-tooth ratchet 631 When the last tooth is on, the single-mouth sheave 63 rotates to the initial position, and then the block on the rotating snap ring 4 cannot be caught, so that the rotating snap ring 4 is released, and the deformed elastic member 5 is released to return to the original state, thereby driving The paddle 101 is reset to the initial position.

Furthermore, in the above embodiment, when the power storage disc 62 rotates, each revolution will be moved by the ratchet 61 to release the half-tooth ratchet 631 until the power storage disc 62 rotates a few times, then the ratchet 61 will move When reaching the last tooth of the half-tooth ratchet 631, the single-mouth sheave 63 rotates to the initial position, and then cannot hang the block on the rotating snap ring 4, so that the rotating snap ring 4 is released. Compared with the direct action of the ratchet 61 on the rotating snap ring 4, this structural design reduces the force on the structure when the elastic member 5 is released and returns to its original state, and avoids the rotation of the rotating snap ring 4 and the carrier 7 due to excessive elastic force. The collision of the sliding structure reduces the energy release of the collision to a certain extent and prolongs the service life to a certain extent.

As yet another embodiment further provided by the present invention, in the embodiment, the swing arm 11 is provided with a spherical protrusion 14 , and the spherical protrusion 14 abuts against the guide slope 2 when it swings up. It can be seen from FIGS. 3 and 4 that a hard spherical protrusion 14 is provided at the end of the swing arm 11 .

As yet another embodiment further provided by the present invention, an infrared emitter with a vertically upward emitting end is installed on the positioning frame, and an infrared receiver is arranged on each paddle 101 . Specifically, in the embodiment, the plectrum 101 rotated to the maximum angle is delayed to reset by the delay mechanism 6. During this time, the infrared emitter is enough to emit infrared rays, and the infrared ray provided at the bottom of the plectrum 101 that has not been tapped Receiver receives. Further, after the infrared receiver on the paddle 101 receives the infrared rays, the data can be transmitted to the mobile phone APP through the wireless connection module, so as to display the students' high touch data, because this technology belongs to those skilled in the art.
