In the such scheme, slide rail is installed on both sides under the double-legged fixed head that described front and back are adjustable, is provided with the cloth cover of two fixing feet above, and the centre is offered chute and is provided with hold-down screw.

In the such scheme, described one group of optoelectronic switch is two of transmitting tube and receiving tubes, is separately fixed on the relative slide block; Or one group of optoelectronic switch is three of transmitting tube, receiving tube and reflective mirrors, and transmitting tube and receiving tube are fixed on the slide block, and reflective mirror is fixed on another relative slide block.

In the such scheme, described head switch is touch switch or standard machinery formula switch.

Digital display sit-ups tester of the present utility model has the following advantages compared with prior art:

1, counts automatically, accurately and reliably.

2, numeral shows, comes into plain view; Also can import test data into computer, so that statistical disposition.

Below in conjunction with drawings and Examples, further specify the utility model.

Fig. 1 to Figure 10 illustrates the structure of digital display sit-ups tester of the present utility model.Referring to figs. 1 through Figure 10, this tester comprises: base plate 1, position governor motion, measuring mechanism, starting switch 25 and electrical measurement control box 26; The position governor motion comprises: the adjustable double-legged fixed head 15 of back-up block and front and back of bending knee that height is adjustable; Measuring mechanism can be a head switch 17 and one group of high-order optoelectronic switch 6, as depicted in figs. 1 and 2; Measuring mechanism also can be two groups of optoelectronic switches of high low level, as shown in figure 13; Base plate 1 both sides are provided with back-up block 2, and vertical columns 3 on the back-up block 2, and slide block 4 is housed on the column 3, and optoelectronic switch 6 is housed on the slide block 4; Circuit board in the electrical measurement control box 26 is provided with counting circuit.Because counting circuit is a prior art, no longer describe in detail here.

With reference to Fig. 5, the adjustable back-up block of bending knee of height comprises: sleeve 9, lifting tube 12, gland 11, spring 10, bend knee piece 8 and lock-screw 13; The piece 8 of bending knee is fixed on the upper end of lifting tube 12, and lifting tube 12, gland 11 and spring 10 are positioned at sleeve 9 successively.Offer a cannelure on the lifting tube 12, lock-screw 13 slides in groove in lifting process, can prevent rotation.

With reference to Fig. 2, slide rail 14 is installed on 15 times both sides of the double-legged fixed head that front and back are adjustable, is provided with the cloth cover 24 of two fixing feet above, and the centre is offered chute and is provided with hold-down screw 16.Both feet fixed head 15 can when transferring to correct position, be tightened hold-down screw 16 along base plate 1 longitudinal sliding motion, prevents that double-legged fixed head 15 from moving in test process.

One group of optoelectronic switch can be separately fixed on the relative slide block 4 for two of transmitting tube and receiving tubes; Or one group of optoelectronic switch is three of transmitting tube, receiving tube and reflective mirrors, and transmitting tube and receiving tube are fixed on the slide block, and reflective mirror is fixed on another relative slide block.

Head switch 17 is touch switch or mechanical switch.Touch switch comprises following two kinds: two blocks of rubber slabs 19,18 that are respectively equipped with horizontal lead and vertical lead, and the centre accompanies isolation sponge 20 with holes, as Fig. 7, Fig. 8 and shown in Figure 9; When not having object to be pressed on the rubber slab, rely on the elastic force of sponge, lead is separated, switch is in off-state; When object is pressed on the rubber slab, the sponge distortion, lead is in contact with one another, switch connection.Perhaps adopt the printed board 23 that is printed on parallel wire, be provided with elasticity supporting ring 21 and conductive rubber 22 above, as Figure 11 and shown in Figure 12; When not having object to press thereon, elasticity supporting ring 21 does not contact conductive rubber 22 with printed board 23, and switch is in off-state; When object is pressed thereon, 21 distortion of elasticity supporting ring, conductive rubber 22 contacts switch connection with printed board 23.

Base plate 1 has regulates leg 27.For making base plate 1 maintenance level, can regulate the height of leg 27, lock with locking nut.Above the base plate 1, be covered with plank, sponge and leather with place that tester's head contacts with the back.

Measuring method: earlier according to tester's height, regulate the height of the back-up block of bending knee, regulate the distance of double-legged fixed head again to the back-up block of bending knee, the tester inserts both feet in the cloth cover, press starting switch after, two hands are lain on the back after intersecting at brain, after hearing the buzzer sound, begin to do sit-ups.When tester's shoulder face contact switch, make switch connection, when shoulder leaves contact-making switch, switch is disconnected, produce a pulse signal, when tester's duplex touches or surpass two knees, the effect of optoelectronic switch generation primary occlusion, also produce an electric impulse signal, these two signal indications are finished sit-ups, and counting once on control box.So repeatedly, can write down the number of times of sit-ups that the tester does.
