Detailed Description

In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1-9, a physical fitness tests data collection device, includes the locating frame, installs axostylus axostyle 100 on the locating frame, rotates on the axostylus axostyle 100 and is provided with a plurality of plectrums 101, has seted up depressed groove and guide slope 2 on the plectrum 101 respectively, and is provided with swing arm 11 in the depressed groove, wherein:

the swing arm 11 on the next layer of shifting piece 101 abuts against the guide slope 2 of the previous layer of shifting piece 101, and a convex part is arranged on the guide slope 2;

when the driving force received by the pick 101 is greater than the preset value, the pick 101 drives the swing arm 11 to pass over the protrusion, and when the driving force received by the pick 101 is less than the preset value, the pick 101 drives the swing arm 11 to fail to pass over the protrusion and reset.

Specifically, in the embodiment, a plurality of the pulling pieces 101 are serially sleeved on the shaft 100 and rotate around the shaft 100. In practice, by adjusting the height of the stand to a suitable height while keeping the paddle 101 and the base of the stand in the same horizontal line (with respect to the state shown in fig. 1), the student jumps up to flap the paddle 101, and the flap 101 that is flapped is deflected. The paddle 101 that has not been struck is held in the initial position (the state shown in fig. 1) due to the abutment of the swing arm 11.

Furthermore, in the embodiment, a concave groove is formed at the top of each of the poking pieces 101, and the guide slopes 2 are symmetrically distributed at the bottom, the guide slopes 2 are of double-peak structures, and in the initial position, the swing arm 11 is located in the concave part between the double-peak structures. The swing arm 11 of the top-most pick 101 abuts against the guiding slope 2 (shown in fig. 9) at the top of the positioning frame, so that each pick 101 obtains a damping force caused by the abutment of the swing arm 11. Furthermore, the swing arm 11 in the embodiment may be an elastic plate, the whole swing arm is an upward swing, and the end part of the elastic plate abuts against the concave part between the two peak structures of the guide slope 2; or the top spring pushes the top to swing upwards, and the end part of the top is abutted against the concave part between the two peak structures of the guide slope 2; or any driving structure known to those skilled in the art for driving the swing arm 11 to swing upwards.

Further, in the embodiment, the driving force received by the paddle 101 is greater than a preset value, which means the force exerted on the paddle 101 by the student tapping the paddle 101 in the test process; when the driving force received by the paddle 101 is smaller than the preset value, it means that in the testing process of the student, the paddle 101 closest to the flapped paddle 101 will generate friction force due to the rotation of the flapped paddle 101 or drive the whole positioning frame or the shaft rod 100 to shake when the paddle 101 is flapped, so as to act on other non-flapped paddles 101. In the embodiment, each layer of the plectrum 101 has a certain damping force in a manner that the swing arm 11 abuts against each layer of the plectrum 101, so that the non-flapped plectrum 101 cannot deflect due to friction or external force, and the topmost plectrum 101 abuts against the positioning frame through the swing arm 11, so that the situation that the whole non-flapped plectrum 101 cannot deflect due to friction or external force is ensured.

It should be noted that, the guide slope 2 in the embodiment is a double-peak structure, and in the initial position, the swing arm 11 is located in the recessed portion between the double-peak structures, and the recessed portion is actually used for positioning, and mainly used for driving the swing arm 11 to not cross the protruding portion and reset when the dial piece 101 resets or the driving force received by the dial piece 101 is smaller than the preset value, and in both cases, the swing arm can completely return to the initial position without manual alignment operation.

In the above embodiment, when the stacked plurality of paddles 101 distributed on the shaft 100 are maintained in the original state, the swing arm 11 on the paddle 101 is swung up and abutted against the paddle 101 at the previous stage, so that the plurality of paddles 101 are abutted against each other through the swing arm 11 to form a whole; when a student beats the plectrum 101, the plectrum 101 is flapped and swung, when the swing arm 11 is separated from the guide slope 2, the lower swing arm 11 is guided by the guide ring sleeve 3 to swing downwards and is separated from one or more plectrums 101 on the upper layer, so that the one or more plectrums 101 on the upper layer which should swing left and right or shake due to friction or vibration are blocked by the friction of the plectrum 101 on the upper layer, and return to the original position under the action of the guide slope 2. Therefore, when a student beats the plectrum 101, one or more plectrum 101 on the upper layer can be prevented from swinging or shaking left and right under the disturbance of friction or vibration factors.

As a further provided embodiment of the present invention, a tension spring 12 is disposed on the swing arm 11, and the tension spring 12 is used for pulling the swing arm 11 to make the upward swing abut against the guide slope 2; when the driving force received by the shifting piece 101 is smaller than the preset value, the lower swing arm 11 is pulled by the tension spring 12 to return to the initial position from the protruding part and drive the shifting piece 101 to reset. Specifically, the swing arm 11 in the embodiment is rotatably disposed in a concave groove on the pick 101, and by pulling of the tension spring 12, the swing arm 11 swings up to abut against a concave portion of the guide slope 2 on the pick 101, so that the pick 101 is held at the initial position. During the test, when the student receives the friction force of the beating paddle 101 acting on the upper paddle 101 or the force generated by vibrating the positioning frame or the shaft 100, the paddle 101 deflects to make it swing left or right, and during the swing, when the rotating force of the paddle 101 is not enough to drive the swing arm 11 to cross the protrusion of the guiding slope 2, the tension spring 12 contracts and pulls to make it swing upward, and finally the swing arm 11 stops in the recess, so that the paddle 101 is kept at the initial position.

Further, the swing arm 11 is driven to swing upwards to abut against the concave part of the guide slope 2 by adopting the pulling manner of the tension spring 12 in the embodiment, and the purpose of the arrangement is as follows: when the plucking piece 101 which is not beaten can be pulled by the tension spring 12, the swing arm 11 slides back into the recess along the protrusion.

As a preferred embodiment of the present invention, as shown in fig. 3, 4 and 5, a guiding ring sleeve 1 is disposed on the shaft 100, a guiding sliding rod 13 is disposed on the swing arm 11, and the guiding sliding rod 13 slides in a sliding slot disposed on the guiding ring sleeve 1; a tension spring 12 is arranged on the swing arm 11, and the tension spring 12 is used for pulling the swing arm 11 to enable the swing arm to abut against the guide slope 2; when the driving force received by the shifting piece 101 is smaller than the preset value and drives the swing arm 11 to be unable to cross the protrusion, the guide slide rod 13 slides along the slide groove to make the swing arm 11 swing to be insufficient to drive the tension spring 12 to swing downwards, and the tension spring 12 pulls to make the swing arm 11 return to the guide slope 2 from the protrusion. Specifically, in the embodiment, the shaft 100 is provided with the guide ring sleeves 1 at intervals, and the bottom of the guide ring sleeve 1 is provided with the carrier 7. The pick 101 in the technical scheme comprises a pick blade and a rotating part, wherein a groove is formed in the bottom of the rotating part, and the carrier 7 is located in the groove and is rotatably connected with the rotating part.

Further, in the embodiment, the guiding ring sleeve 1 is provided with a guiding slot (shown in fig. 5), and the end of the guiding rod 13 of the swing arm 11 is located in the guiding slot. In a specific embodiment, students test to jump and tap paddle 101, and paddle 101 is respectively present in the following states:

when the patted paddle 101 rotates, the swing arm 11 slides along the concave portion of the guide slope 2 toward the convex portion, and receives a force larger than the damping force of the swing arm 11 sliding along the concave portion toward the convex portion, the swing arm 11 goes over the convex portion. When the sliding guide rod passes over the convex part, the sliding guide rod 13 slides in the sliding guide groove along with the rotation of the poking piece 101, and meanwhile, the swing arm 11 swings downwards to a certain angle, the tension spring 12 pulls the swing arm 11 to swing downwards to enter the sliding guide concave groove. When the swing arm 11 is pulled by the tension spring 12 to swing downwards actively, the guide sliding rod 13 slides along the guide sliding groove actively, so that the poking piece 101 is driven to rotate actively and stops after rotating to the maximum rotation angle, the phenomenon that when the poking piece 101 is patted, the poking piece 101 receives too large driving force, when the poking piece 101 reaches a preset angle, the poking piece 101 receives a reaction force, the poking piece 101 rotates in the opposite direction, and the phenomenon that fingers of students are injured by rebounding rotation of the poking piece 101 is avoided;

while the non-slapping pick 101 deflects due to the friction of the slapping pick 101 acting on the upper pick 101 or the force generated by vibrating the positioning frame or shaft 100, so that it swings left or right. When the rotating force of the pick is insufficient to drive the swing arm 11 to go over the protrusion of the guide slope 2 during the swinging process, the tension spring 12 contracts and pulls to swing up, and finally the swing arm 11 stops in the recess, so that the pick 101 is kept at the initial position.

As a further embodiment of the present invention, a rotary snap ring 4 is provided on the pick 101, and an elastic member 5 is provided on the rotary snap ring 4, and the elastic member 5 is used for keeping the pick 101 at the original station; when the driving force received by the pick 101 is greater than the preset value, it swings to deform the elastic member 5 under force. Specifically, a rotary snap ring 4 is provided in the groove of the rotary part, and the elastic member 5 is an elastic piece, one end of which is installed in the through groove of the carrier 7, and the other end of which abuts against the rotary snap ring 4, so that the pick 101 is kept at the initial position in a normal state. When the patted paddle 101 rotates, the swing arm 11 slides along the concave portion of the guide slope 2 toward the convex portion, and receives a force greater than the damping force of the swing arm 11 sliding along the concave portion toward the convex portion, the swing arm 11 goes over the convex portion. When the sliding guide rod passes over the convex part, the sliding guide rod 13 slides in the sliding guide groove along with the rotation of the poking piece 101, and meanwhile, the swing arm 11 swings downwards to a certain angle, the tension spring 12 pulls the swing arm 11 to swing downwards to enter the sliding guide concave groove. When the swing arm 11 is pulled by the tension spring 12 to swing downwards actively, the sliding guide rod 13 slides along the sliding guide groove actively, so as to drive the shifting piece 101 to rotate actively, and after the shifting piece rotates to the maximum rotation angle, the elastic piece 5 is in a deformation state at the moment, the elastic piece 5 is released to recover the original state, and thus the shifting piece 101 is driven to reset to the initial position.

As a further embodiment provided by the present invention, the beating of the paddle 101 in the above embodiment is followed by instantaneous reset, which has two problems, that is, the first is elastically reset, the reset interval is short, and the electronic detector reaction is not facilitated; after flapping paddle 101 is deflected to the maximum rotation angle, its instantaneous reset tends to hurt the student's fingers. To this end, the present invention provides an embodiment to solve the problem, that is, a delay mechanism 6 is added, the delay mechanism 6 includes a pawl 61 and a power storage disc 62, and a trigger slot 621 is provided on the power storage disc 62; when the power storage disc 62 rotates to make the pawl 61 be picked up by the trigger groove 621 to release the rotary snap ring 4 to reset the pick 101. Specifically, the delay mechanism 6 in the above technical solution mainly functions to convert the instantaneous reset of the paddle 101 into a delayed reset, and increase the interval therebetween, thereby ensuring the data acquisition of the electronic detector and ensuring that the reset mechanism drives the paddle 101 to reset without causing accidental injury time.

Further, in the embodiment, a concave groove is formed in one side of the power storage disc 62, the torsion spring 622 is installed in the concave groove, the power storage disc 62 is rotatably arranged on the carrier 7, the power storage disc 62 can synchronously rotate along with the rotary clamp ring 4, and the power storage disc can be in a gear structure; or a pulley drive or a synchronous drive known to those skilled in the art. When the rotary snap ring 4 rotates, the pawl 61 does not have the locking capability, and the rotation thereof toggles the pawl 61 to swing (the pawl 61 is rotatably arranged on the carrier 7). Further, a protrusion is disposed on the top of the power storage disc 62, and an iron ring is disposed on the protrusion, and one side of the iron ring is recessed, i.e. a trigger groove 621.

In a specific embodiment, when the paddle 101 is flapped to reach the maximum rotation angle, the rotary snap ring 4 is locked by the pawl 61. When the torsion spring 622 on the power storage disc 62 is released and returns to the original state, the power storage disc 62 rotates, and since the power storage disc 62 is installed through the rotation damping bearing, the rotation speed of the power storage disc 62 is kept within a predetermined range, and after the power storage disc 62 rotates by a predetermined angle, the pawl 61 is driven to poke, and the rotary snap ring 4 is released. The deformed elastic member 5 is released to return to the original state, thereby driving the pick 101 to return to the original position.

As a further preferred embodiment of the present invention, as shown in fig. 6 and 8, the delay mechanism 6 includes a single-opening grooved wheel 63, a clamping block is disposed on the rotary clamping ring 4, and the rotary clamping ring 4 and the power accumulating disc 62 rotate synchronously; when the driving force received by the poking piece 101 is larger than the preset value, the rotary clamping ring 4 swings along with the poking piece, the clamping block pushes the single-opening grooved wheel 63 to rotate for a preset angle, and the single-opening grooved wheel 63 is locked by the pawl 61. Specifically, in the above technical solution, the single grooved wheel 63 is rotatably disposed on the carrier 7, and the single grooved wheel 63 and the power storage disc 62 are in transmission connection through a belt, and when the dial plate 101 rotates due to flapping, the dial plate rotates until the sliding guide 13 is located in the sliding guide slot and slides to a position where the swing arm 11 swings downward by an angle enough to drive the tension spring 12, so that the swing arm 11 swings downward quickly. At this time, the clamping block on the rotary clamping ring 4 drives the clamping block to be clamped in the single-opening grooved wheel 63 and drives the single-opening grooved wheel 63 to rotate, and the synchronous power storage disc 62 synchronously rotates, so that the torsion spring 622 stores power.

Further, in the above technical solution, as can be seen from fig. 6, a half-tooth ratchet 631 is provided on the single-port sheave 63; when the power storage plate 62 rotates to make the pawl 61 be picked by the trigger slot 621 to dial the half-tooth ratchet 631 to rotate by a predetermined angle. Specifically, in the embodiment, when the half-tooth ratchet 631 rotates along with the single-port grooved wheel 63, the pawl 61 does not have the locking capability, and the rotation thereof can toggle the pawl 61 to swing (because the iron ring is an elastic structure, the pawl 61 can be elastically released by the iron ring to reset when swinging), so as to lock the single-port grooved wheel 63. When the rotation angle of the pick 101 reaches the maximum, the single-opening grooved wheel 63 cannot be rotated by the rotation snap ring 4 under the limitation of the pawl 61. At this time, the power storage disc 62 rotates, each circle of the power storage disc is shifted by the pawl 61, the half-tooth ratchet 631 is released, until the power storage disc 62 rotates for several circles, when the pawl 61 shifts to the last tooth of the half-tooth ratchet 631, the single-opening grooved wheel 63 rotates to the initial position, the clamping block on the rotary clamping ring 4 cannot be hung, the rotary clamping ring 4 is released, the deformed elastic piece 5 is released to restore to the original state, and the shifting piece 101 is driven to reset to the initial position.

Further, in the above embodiment, the power storage disc 62 rotates, and each circle of the power storage disc 62 is shifted by the pawl 61 to release the half-tooth ratchet 631, until after the power storage disc 62 rotates several circles, when the pawl 61 shifts to the last tooth of the half-tooth ratchet 631, the single-opening grooved wheel 63 rotates to the initial position, and cannot catch the latch on the rotary snap ring 4, so that the rotary snap ring 4 is released. Compare direct pawl 61 and act on to rotation snap ring 4, this structural design has reduced elastic component 5 and has released and resume original condition, acts on the power of structure, avoids causing the collision of rotation snap ring 4 and microscope carrier 7 sliding construction because elasticity is too big, has reduced the release energy of this kind of striking to a certain extent, in the extension of certain degree life.

As a further embodiment of the present invention, in the embodiment, the swing arm 11 is provided with a spherical convex portion 14, and the spherical convex portion 14 abuts on the guide slope 2 when swinging. As can be seen from fig. 3 and 4, a hard spherical boss 14 is provided at an end of the swing arm 11.

As a further embodiment provided by the present invention, an infrared emitter with an emitting end facing vertically upwards is installed on the positioning frame, and an infrared receiver is installed on each of the dials 101. Specifically, in the embodiment, the reset of the paddle 101 rotated to the maximum angle is delayed by the delay mechanism 6, and the infrared transmitter can emit infrared rays in the time period enough to be received by the infrared receiver arranged at the bottom of the paddle 101 which is not beaten. Further, after the infrared receiver on the pick-up 101 receives the infrared ray, the data can be transmitted to the mobile phone APP through the wireless connection module, so as to display the altitude data of the student.
