The bouncing test mainly uses a standing long jump tester or a altitude touch machine. The altitude touch machine mainly comprises a supporting seat, a positioning frame, a rotating shaft and a plurality of poking sheets rotating on the rotating shaft, wherein the heights of the positioning frame are adjusted through the supporting seat, the poking sheets are shot by the bouncing of students, and the bouncing capacity of the students is determined by observing the poking sheet heights which are poked.

According to patent number CN202120037617.6, publication (bulletin) day: 2021-10-15 discloses an automatic reset type altitude touch machine, which comprises a supporting pedestal and is characterized in that the top end of the supporting seat is provided with a positioning frame, one end of the positioning frame, which is far away from the supporting seat, is provided with an opening, a main shaft and a plurality of shifting sheets are rotationally arranged on the main shaft, a fixed shaft is further arranged on the positioning frame, two reset frames and two reset frames are rotationally arranged on the fixed shaft in a opposite direction, a movable shaft is slidably arranged on the positioning frame, the main shaft, the fixed shaft and the movable shaft are sequentially arranged from the opening to the supporting seat, two rotating frames and the two rotating frames are oppositely arranged on the movable shaft, the rotating frames are hinged with the reset frames, a reset rope is arranged on the movable shaft, the free end of the reset rope penetrates through the supporting seat and the positioning frame and extends to the direction far away from the positioning frame, and when the movable shaft moves to the direction close to the supporting seat, the two reset frames and the two rotating frames are driven to move close to each other, and the reset frames can be contacted with the shifting sheets. When the moving shaft moves towards the direction close to the supporting seat, the two reset frames and the two rotating frames are driven to move close to each other, the reset frames can be contacted with the poking sheets, the left hand and the right hand are supported to touch high and run bidirectionally, and the poking sheets can be reset rapidly.

The collection of the altitude touch machine data in the market is mainly based on human eye collection, and if the electronic sensor is used for detecting the shifting sheet displacement to collect the altitude touch data, the data collection is quicker compared with human eye observation. The distribution of the pulling sheets of the altitude touch machine on the market is mainly two types: the first is that the pulling sheets are stacked and placed in contact with each other; the second is that each plectrum keeps a preset interval, and the interval is very small. In both assembly cases, no exception is taken, when the fingers of a student can touch the highest-level plectrum and drive the plectrum to deflect, one or more plectrums at the upper layer are fluctuated to deflect at a certain angle, so that the electronic sensor is used for acquiring data of the swinging of the plectrum more difficultly, and if the sensor or the pressure sensor is touched on the plectrum, the purchase cost of the whole altitude touch machine is increased; or the problem is solved by setting the fuzzy value through a program, and the deflection angle of the plectrum caused by the fluctuation of the beating of the plectrum and the magnitude of the force generated by beating can not be estimated, which is obviously unrealistic.

Detailed Description

In order to make the technical scheme of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1-9, a physical health test data collection device, including the locating frame, install axostylus axostyle 100 on the locating frame, rotate on the axostylus axostyle 100 and be provided with a plurality of plectrum 101, set up sunken groove and guide slope 2 on the plectrum 101 respectively, and be provided with swing arm 11 in the sunken groove, wherein:

the swing arm 11 on the next layer of plectrum 101 is abutted against the guide slope 2 of the previous layer of plectrum 101, and a protruding part is arranged on the guide slope 2;

when the driving force received by the pulling piece 101 is larger than a preset value, the pulling piece drives the swing arm 11 to pass over the protruding part, and when the driving force received by the pulling piece 101 is smaller than the preset value, the pulling piece drives the swing arm 11 to fail to pass over the protruding part and reset.

Specifically, in the embodiment, a plurality of paddles 101 are sleeved on the shaft 100 in series, and rotate around the shaft 100 as an axis. In actual operation, by adjusting the height of the stand to reach a proper height, and simultaneously keeping the plectrum 101 and the base of the stand on the same horizontal line (in the state shown in fig. 1), the student jumps up to flap the plectrum 101, and the plectrum 101 subject to the flap is flap and deflected. The striking plate 101 that is not struck is kept at the initial position (the state shown in fig. 1) due to the contact of the swing arm 11.

Further, in the embodiment, the top of each of the paddles 101 is provided with a concave groove, while the bottom is provided with symmetrically distributed guiding slopes 2, the guiding slopes 2 are of a double-peak structure, and the swing arm 11 is located at a concave part between the double-peak structures in the initial position. The top-most pulling piece 101 has its swing arm 11 abutting against the guide slope 2 (shown in fig. 9) at the top of the positioning frame, so that each pulling piece 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 a pendulum, and the end part of the swing arm is abutted on the concave part between the two peak structures of the guiding slope 2; or the guide slope is pushed by the top spring to swing upwards, and the end part of the guide slope is abutted on 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 up.

Further, in the embodiment, the driving force received by the pulling sheet 101 is greater than a preset value, which means that the force applied to the pulling sheet 101 by the pulling sheet 101 is applied in the test process of the student; when the driving force received by the plectrum 101 is smaller than the preset value, the plectrum 101 closest to the plectrum 101 to be beaten will drive the whole positioning frame or the shaft rod 100 to shake to act on other plectrums 101 not beated due to the friction force generated by the rotation of the plectrum 101 to be beaten or the shaking of the plectrum 101 during the test of students. In the embodiment, since each layer of the paddles 101 is abutted by the swing arm 11, a certain damping force exists on each paddle 101, so that the paddles 101 which are not beaten cannot deflect due to friction force or external force, and the paddles 101 at the topmost layer are abutted on the positioning frame through the swing arm 11, so that the situation that all paddles 101 which are not beaten cannot deflect integrally due to friction force or external force is ensured.

It should be noted that, in the embodiment, the guiding slope 2 is of a bimodal structure, when the swing arms 11 are located in the concave portions between the bimodal structures in the initial position, the concave portions are actually provided for positioning, mainly for resetting the pulling sheet 101 or when the driving force received by the pulling sheet 101 is smaller than a preset value, the swing arms 11 are driven to go over the convex portions and reset, and in both cases, the swing arms can completely return to the initial position without manual alignment operation.

In the above embodiment, when the plurality of paddles 101 stacked and distributed on the shaft 100 are kept in the original state, the swing arms 11 on the paddles 101 swing up to abut against the paddles 101 at the previous stage, so that the plurality of paddles 101 abut against each other to form a whole through the swing arms 11; when students flap 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 at the moment is guided by the guide ring sleeve 3 to be separated from the plectrum 101 at the upper layer, so that the plectrum 101 at the upper layer, which is supposed to be rubbed or vibrated to swing or shake left and right, is blocked by the friction force of the plectrum 101 at the upper layer, and returns to the original position under the action of the guide slope 2. Thereby avoiding the left and right swinging or swaying of one or more plectrum 101 on the upper layer due to the disturbance of friction force or vibration factor when students flap the plectrum 101.

As a further provided embodiment of the present invention, the swing arm 11 is provided with a tension spring 12, and the tension spring 12 is used for pulling the swing arm 11 to enable the upper swing to be abutted against the guide slope 2; when the driving force received by the pulling piece 101 is smaller than the preset value, the swing arm 11 is pulled down by the tension spring 12, returns to the initial position by the protruding part and drives the pulling piece 101 to reset. Specifically, the swing arm 11 in the embodiment is rotatably disposed in a recess groove on the dial 101, and the swing arm 11 swings up to abut in the recess of the guide slope 2 on the dial 101 by the pulling of the tension spring 12, so that the dial 101 is held in the initial position. During the test, when the student receives the friction force of the plectrum 101 which is beaten on the plectrum 101 and acts on the upper layer or the force generated by vibrating the positioning frame or the shaft lever 100, the plectrum 101 deflects to enable the plectrum 101 to swing left or right, and during the swinging process, the rotation force of the plectrum 101 is insufficient to drive the swinging arm 11 to pass over the convex part of the guiding slope 2, the tension spring 12 contracts and pulls to enable the plectrum 11 to swing upwards, and finally the swinging arm 11 is stopped in the concave part, so that the plectrum 101 is kept in the initial position.

Further, in the embodiment, the swing arm 11 is driven to swing upwards by the pulling of the tension spring 12 to be abutted in the concave part of the guiding slope 2, and the purpose of the arrangement is that: when the non-beaten plectrum 101 can be pulled by the tension spring 12, the swing arm 11 slides back into the concave part along the convex part.

As a further provided preferred embodiment of the present invention, according to fig. 3, 4 and 5, a guide ring sleeve 1 is provided on a shaft lever 100, a guide sliding rod 13 is provided on a swing arm 11, and the guide sliding rod 13 slides in a sliding groove provided on the guide ring sleeve 1; the swing arm 11 is provided with a tension spring 12, and the tension spring 12 is used for pulling the swing arm 11 to enable the swing arm 11 to swing upwards to be abutted against the guide slope 2; when the driving force received by the pulling piece 101 is smaller than a preset value, and the pulling piece drives the swing arm 11 to pass over the protruding part, the sliding guide rod 13 slides in the sliding groove to enable the swing arm 11 to swing insufficiently to drive the tension spring 12 to swing downwards, and the tension spring 12 pulls to enable the swing arm 11 to return to the guide slope 2 from the protruding part. Specifically, in the embodiment, the guide ring sleeves 1 are fixedly arranged on the shaft rod 100 at intervals, and the carrier 7 is arranged at the bottom of the guide ring sleeve 1. The plectrum 101 in the technical scheme includes plectrum and rotation portion, and the recess has been seted up to the bottom of rotation portion, and carrier 7 is located the recess to be connected for rotating with rotation portion.

Further, the guide ring 1 in the embodiment is provided with a guide chute (shown in fig. 5), and the end of the guide rod 13 on the swing arm 11 is located in the guide chute. In a specific embodiment, the student tests to jump up and tap the plectrum 101, and the plectrum 101 exists in the following states:

when the beating paddle 101 rotates, the swing arm 11 slides along the concave part of the guiding slope 2 to the convex part, the received force is larger than the damping force of the swing arm 11 sliding along the concave part to the convex part, and then the swing arm 11 passes over the convex part. When the pulling piece 101 just passes over the protruding part, the sliding guide rod 13 slides in the sliding guide groove along with the rotation of the pulling piece 101, meanwhile, the swing arm 11 is swung down to a certain angle, and the swing arm 11 is swung down into the sliding guide concave groove under the traction of the tension spring 12. When the swing arm 11 is pulled by the tension spring 12 to actively swing down, the guide slide bar 13 actively slides along the guide slide groove, so that the plectrum 101 is driven to actively rotate and stops after rotating to the maximum rotation angle, the condition that the plectrum 101 receives excessive driving force when being flapped to the plectrum 101, and when the driving force reaches a preset angle, the plectrum 101 receives reaction force to enable the plectrum 101 to reversely rotate, and the condition that the plectrum 101 causes accidental injury to fingers of students because of rebound rotation is avoided;

the non-beaten plectrum 101 is deflected by the friction force of the plectrum 101 which is beaten and acts on the plectrum 101 at the upper layer or the force generated by vibrating the positioning frame or the shaft lever 100, so that the plectrum 101 swings left or right. In the swinging process, when the rotation force of the shifting piece is insufficient to drive the swing arm 11 to pass over the protruding part of the guide slope 2, the tension spring 12 is contracted and pulled to swing up, and finally the swing arm 11 is stopped in the concave part, so that the shifting piece 101 is kept in the initial position.

As still another embodiment provided by the invention, the rotary snap ring 4 is arranged on the plectrum 101, the elastic piece 5 is arranged on the rotary snap ring 4, and the elastic piece 5 is used for keeping the plectrum 101 at the original station; when the driving force received by the paddle 101 is greater than a preset value, it swings to deform the elastic member 5 by force. Specifically, the rotary snap ring 4 is disposed in the groove of the rotary part, the elastic member 5 is an elastic sheet, one end of the elastic member is mounted in the through groove on the carrier 7, and the other end of the elastic member abuts against the rotary snap ring 4, so that the dial 101 is kept at the initial position in a normal state. And the beating plectrum 101 rotates, and the swing arm 11 slides to the bulge along the concave part of the guide slope 2, and the received force is greater than the damping force of the swing arm 11 sliding to the bulge along the concave part, so that the swing arm 11 passes over the bulge. When the pulling piece 101 just passes over the protruding part, the sliding guide rod 13 slides in the sliding guide groove along with the rotation of the pulling piece 101, meanwhile, the swing arm 11 is swung down to a certain angle, and the swing arm 11 is swung down into the sliding guide concave groove under the traction of the tension spring 12. When the swing arm 11 is pulled by the tension spring 12 to actively swing down, the guide slide rod 13 actively slides along the guide slide groove, so that the plectrum 101 is driven to actively rotate, and after the plectrum rotates to the maximum rotation angle, the elastic piece 5 is in a deformation state, and the elastic piece 5 is released to restore to the original state, so that the plectrum 101 is driven to restore to the initial position.

As still another embodiment of the present invention, the beating of the paddle 101 in the above embodiment is followed by an instantaneous reset, which has the following two problems, that is, the first elastically reset, the reset interval is short, which is not beneficial to the reaction of the electronic detector; after the flap 101 is deflected to the maximum rotation angle, it is instantaneously reset to easily hurt the fingers of the student. To this end, the invention provides an embodiment in which a delay mechanism 6 is added, the delay mechanism 6 includes a pawl 61 and a force storage plate 62, and a trigger slot 621 is provided on the force storage plate 62; when the power storage disc 62 rotates to enable the pawl 61 to be picked up by the trigger groove 621 to release the rotary snap ring 4 to reset the pulling piece 101. Specifically, the main function of the delay mechanism 6 in the above technical scheme is to change the instantaneous reset of the plectrum 101 into the delayed reset, and increase the middle interval, so that the data acquisition of the electronic detector is ensured, and meanwhile, the reset mechanism is ensured to drive the plectrum 101 to reset, so that the occurrence of accidental injury time is avoided.

Further, in the embodiment, a concave groove is formed on one side of the power storage disc 62, and the torsion spring 622 is installed in the concave groove, the power storage disc 62 is rotatably disposed on the carrier 7, and the power storage disc 62 can synchronously rotate along with the rotating snap ring 4, and can pass through a gear structure; either a pulley transmission or a synchronous transmission known to those skilled in the art. When the rotating snap ring 4 rotates, the pawl 61 does not have the locking capability, and rotation thereof will toggle the pawl 61 to swing (the pawl 61 is rotatably provided on the carrier 7). Further, a protruding portion is provided at the top of the power storage plate 62, and an iron ring is provided on the protruding portion, and a side of the iron ring is concave, that is, a trigger groove 621.

In a specific embodiment, when the paddle 101 is flapped to a maximum rotation angle, the rotating collar 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 the rotation speed of the power storage disc 62 is kept within a preset range because the power storage disc 62 is installed through the rotary damping bearing, so that after the power storage disc 62 rotates by a preset angle, the pawl 61 is driven to toggle, and the rotary clamping ring 4 is released. The deformed elastic member 5 is released to restore the original state, thereby driving the dial 101 to return to the original position.

As a further provided preferred embodiment of the present invention, according to fig. 6 and 8, the delay mechanism 6 includes a single-port sheave 63, a clamping block is provided on the rotating snap ring 4, and the rotating snap ring 4 rotates synchronously with the power storage disc 62; when the driving force received by the pulling piece 101 is greater than a preset value, the rotary snap ring 4 swings along with the driving force, the clamping block pushes the single-port grooved pulley 63 to rotate by a preset angle, and the single-port grooved pulley 63 is locked by the pawl 61. Specifically, in the above technical solution, the single-port sheave 63 is rotatably disposed on the carrier 7, and the single-port sheave 63 and the power storage disc 62 are in transmission connection through a belt, when the paddle 101 is flapped to rotate, the single-port sheave 63 rotates until the slide guiding rod 13 is located in the slide guiding groove and slides to a position where the swing arm 11 swings downwards by an angle sufficient to drive the tension spring 12, so that the swing arm 11 swings downwards rapidly. At this time, the clamping block on the rotary clamping ring 4 drives the clamping block in the single-port grooved pulley 63 and drives the single-port grooved pulley 63 to rotate, and the synchronous force storage disc 62 synchronously rotates, so that the torsion spring 622 stores force.

Further, in the above technical solution, as can be seen from fig. 6, a half-tooth ratchet ring 631 is disposed on the single-port sheave 63; when the power storage disk 62 rotates, the pawl 61 is picked up by the trigger slot 621 to toggle the half-tooth ratchet ring 631 to rotate by a predetermined angle. Specifically, in the embodiment, when the half-tooth ratchet 631 rotates along with the single-port sheave 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 of an elastic structure, because the pawl 61 is reset due to elastic energy release of the iron ring when swinging), thereby locking the single-port sheave 63. When the rotation angle of the pulling piece 101 reaches the maximum, the single-port grooved wheel 63 cannot be pulled to rotate by the rotary clamping ring 4 under the limit of the pawl 61. At this time, the power storage disc 62 rotates, each circle can be stirred by the pawl 61 to release the half-tooth ratchet ring 631, until the pawl 61 stirs to the last tooth of the half-tooth ratchet ring 631 after the power storage disc 62 rotates for several circles, the single-mouth grooved pulley 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, and the deformed elastic piece 5 is released to restore to the original state, so that the pulling piece 101 is driven to be reset to the initial position.

Further, in the above embodiment, when the power storage disc 62 rotates, each circle is shifted by the pawl 61 to release the half-tooth ratchet ring 631 until the power storage disc 62 rotates for several circles, when the pawl 61 is shifted to the last tooth of the half-tooth ratchet ring 631, the single-mouth sheave 63 rotates to the initial position, so that the clamping block on the rotating clamping ring 4 cannot be hung, and the rotating clamping ring 4 is released. Compared with the direct pawl 61 acting on the rotary clamping ring 4, the structural design reduces the force of the elastic piece 5 for releasing and recovering the original state and acting on the structure, avoids collision of the rotary clamping ring 4 and the sliding structure of the carrying platform 7 due to overlarge elastic force, reduces the release energy of the collision to a certain extent and prolongs the service life to a certain extent.

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

As still another embodiment of the present invention, the positioning frame is provided with an infrared emitter with an emitting end vertically upward, and each of the dials 101 is provided with an infrared receiver. Specifically, in the embodiment, the setting of the paddle 101 rotated to the maximum angle is delayed by the delay mechanism 6, and during this time, enough infrared emitters throw infrared rays and can be received by the infrared receiver arranged at the bottom of the paddle 101 which is not being beaten. Further, after the infrared receiver on the dial 101 receives the infrared, the data can be transmitted to the mobile phone APP through the wireless connection module, so as to display the altitude touch data of the student.
