Abstract
A kind of sit-ups Counting teaching aid, including service creeper and controller, it is characterised in that：The service creeper end is provided with support bar group, and foot fix bar is provided with the support bar group, and the foot fix bar is provided with torque spring with support bar group junction, and limiter is additionally provided with the torque spring；The foot fix bar is U-tube, and buffering sponges cover is provided with the foot fix bar.It is of the present utility model to be beneficial in that：The device structure is simple, easy to use, can automatic sensing specification act and record sit-ups quantity, while can effectively report achievement.
Description
First, technical field
A kind of realia is the utility model is related to, more particularly to a kind of sit-ups Counting teaching aid.
2nd, background technology
" sit-ups " are the sports projects that a middle and primary schools generally carry out, and to rise up into senior middle school necessary by junior middle school student
A content up to standard, otherwise will be unable to rise up into senior middle school.Therefore, all schools all carry out this physical culture item in positive tissue student
Mesh is trained, to meet Achievement Test actively to prepare for war.Regrettably some students can not be risen because this achievement is not up to standard every year
Enter senior middle school.Caused by this is any reasonDrawn a conclusion by investigating further：Act lack of standardization, cause in Achievement Test
In break the rules repeatedly.Certainly, outside the self reason of student, the erroneous judgement problem also judged often is learned among examination
The raw quarrel between judge, it is whose problem actually, it is difficult to define.Sit-ups have strict specification action：Will during match
Both hands embrace head, and after lying down, the distance on head and ground is considered as not in place, exercise void if greater than 5cm between 0-5cm；Sit up
When, upper body will keep plumbness, can turn forward, but can not swing back, and otherwise exercise void, disregards achievement.Instructed usually
In white silk, although P.E. teacher corrects malfunction for classmates repeatedly, because full class's number is too many, and everyone is at least
Need to do up to a hundred actions, therefore teacher can not possibly be completely with respect to also with regard to thinking that lazy student has buried hidden danger for those.It is existing
On the market can automatic sensing specification act and record sit-ups quantity, while can effectively report having lain on the back for achievement
Sit Counting teaching aid not to be found also, have to be developed.
3rd, utility model content
In order to overcome the weak point of existing realia, the utility model provides a kind of sit-ups Counting teaching aid.
What the technical solution of the utility model was realized in.
A kind of sit-ups Counting teaching aid of this programme, including service creeper and controller, it is characterised in that：The service creeper end
Support bar group is provided with, foot fix bar is provided with the support bar group, the foot fix bar is set with support bar group junction
Torque spring is equipped with, limiter is additionally provided with the torque spring；The foot fix bar is U-tube, the foot fix bar
On be provided with buffering sponges cover；
The service creeper side is provided with the slideway extended from service creeper one end to the other end, and two cunnings are provided with the slideway
Platform, arbitrarily it is provided with the slide unit perpendicular to slideway and last to the connecting rod away from the extension of service creeper direction, any connecting rod
End is provided with the expansion link perpendicular to service creeper surface, and any expansion link top is provided with reflection infrared sensor, arbitrarily
Polariscope is provided with the infrared-ray head of the reflection infrared sensor；Any reflection infrared sensor with
Controller electrically connects；
Operating key group is provided with the controller, the operating key group includes start button and reset key；
Digital display screen and loudspeaker are provided with the controller.
It is of the present utility model to be beneficial in that：The device structure is simple, easy to use, being capable of the action of automatic sensing specification
And sit-ups quantity is recorded, while can effectively report achievement.
4th, illustrate
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of service creeper 1 of the present utility model.
5th, embodiment
Brief description is made to specific embodiment of the present utility model below in conjunction with the accompanying drawings.
A kind of sit-ups Counting teaching aid as depicted, including service creeper 1 and controller 11, it is characterised in that：It is described to lie
The end of plate 1 is provided with support bar group 3, and foot fix bar 4 is provided with the support bar group 3, the foot fix bar 4 and support bar
3 junctions of group are provided with torque spring, and limiter 6 is additionally provided with the torque spring；The foot fix bar 4 is U-tube, institute
State and buffering sponges cover 5 is provided with foot fix bar 6；
The side of service creeper 1 is provided with the slideway 2 extended from the one end of service creeper 1 to the other end, and two are provided with the slideway 2
Slide unit 7, the connecting rod 15 for being arbitrarily provided with the slide unit 7 perpendicular to slideway 2 and extending to the remote direction of service creeper 1, arbitrarily
The end of connecting rod 15 is provided with the expansion link 8 perpendicular to the surface of service creeper 1, and any top of expansion link 8 is provided with reflective red
Outer sensor 9, arbitrarily it is provided with polariscope 10 on the infrared-ray head of the reflection infrared sensor 9；It is any described anti-
Formula infrared sensor 9 is penetrated to electrically connect with controller 11；
Operating key group 12 is provided with the controller 11, the operating key group 12 includes start button and reset key；
Digital display screen 13 and loudspeaker 14 are provided with the controller 11.
The course of work of this example：When using the utility model, people is lain on service creeper 1, and pin is pressed by foot fix bar 4
Push down, then fixed by limiter 6, buffering sponges cover 5 can effectively prevent foot from being weighed wounded by foot fix bar 4, then say
One slide unit 7 is moved to the head position of people, and then the height of adjustable telescopic rod 8 and the height of reflection infrared sensor 9, make
It can sense the normal place on head, then adjust the position of another slide unit 7, and its corresponding expansion link 8, reflective
The height and angle of infrared sensor 9, can sense people sit up after normal place, then pass through operating key group 12
Reset key the numerical value sensed before is reset, press start button and start counting up, while controller 11 starts countdown, people do
When sit-ups, the reflection infrared sensor 9 on head and the reflection infrared sensor 9 after sitting up have sensing
Afterwards, the numeral on digital display screen 13 adds one to record numerical value, and after the timing of controller 11 terminates, loudspeaker 14 can send count off sound
And announce results, while polariscope 10 and reflection infrared sensor 9 can effectively reduce sunshine to reflective infrared biography
The interference of sensor 9, make sensing sensitiveer.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
