Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
It is provided by Fig. 1 to Fig. 4, a kind of correcting appliance for students, including pedestal 1, pedestal 1, which slides back and forth, is connected with backrest 2, pedestal
1 right end is equipped with the rotation axis 3 that front and back is placed, and 3 outer edge surface of rotation axis is equipped with curved groove 4, and 2 right end of backrest is fixed with insertion curved groove
4 sliding block 5, rotation axis 3 rotate, and curved groove 4 slides back and forth with movable slider 5, and then backrest 2 slides back and forth on pedestal 1；
1 lower end of pedestal is equipped with transmission shaft 6, and 6 spline of transmission shaft is connected with shaft 7, and 7 rear end of shaft is fixed with first bevel gear
8,2 lower end of backrest is fixed with the fixed block 10 positioned at the lower section of pedestal 1, and the engaged with first bevel gear 8 is equipped in fixed block 10
Two bevel gears 9, second bevel gear 9 are coaxially fixed with the lead screw 11 inside backrest 2, and lead screw 11 is threaded with nut 12,
Nut 12 is fixed with transverse slat 13, and 13 left and right ends of transverse slat are symmetrically arranged with clamping plate 14.
The rotation axis 3 is coaxially fixed with ratchet 15 and going barrel 16, and the corresponding spine of ratchet 15 is fixed on pedestal 1
Pawl.
1 lower end of pedestal is fixed with multiple support columns 17, for guaranteeing the height of pedestal 1 and maintaining the flat of pedestal 1
Weighing apparatus property.
The guide rail 18 slided up and down with nut 12 is fixed in the backrest 2.
1 lower end of pedestal is equipped with the sliding groove 19 slid back and forth with fixed block 10, is conducive to fixed block 10 and backrest 2
Entirety slides back and forth.
14 upper end of clamping plate be it is arc-shaped, be conducive to the fixation of student's shoulder.
It is equipped with I-shaped slot 20 corresponding with backrest 2 in the pedestal 1, offers in pedestal 1 and slid back and forth with sliding block 5
Through slot 21.
When the utility model is used, 1 lower end of pedestal is fixed with multiple support columns 17, for guaranteeing the normal height of pedestal 1
Degree, and 1 balance of pedestal is maintained, when student is sitting on pedestal 1, according to the fat or thin difference of each student, need appropriate
Adjust the longitudinal separation of backrest 2, at this time rotary motion axis 3, rotation axis 3 drives curved groove 4 to rotate, curved groove 4 with movable slider 5 to
Front slide, sliding block 5 are fixedly connected with backrest 2, and I-shaped slot 20 corresponding with backrest 2 is equipped in pedestal 1, offered in pedestal 1 with
The through slot 21 that sliding block 5 slides back and forth, and then backrest 2 effectively ensures that backrest 2 in pedestal 1 in 20 slides forwards of I-shaped slot
The stationarity of sliding, and then backrest 2 can be close to the back of student, guarantee student's back is in straight and upright state, avoids hunchback
The phenomenon that, under the collective effect of 15 pawl of going barrel 16 and ratchet, rotation axis 3 can be effectively prevented and reverse, Jin Eryou
The position of the fixed backrest 2 in effect ground；
2 lower end of backrest is fixed with fixed block 10, and 1 lower end of pedestal is equipped with the sliding groove 19 slid back and forth with fixed block 10,
During 2 forward slip of backrest, fixed block 10 is in 19 slides forwards of sliding groove, since shaft 7 and 6 spline of transmission shaft connect
It connects, backrest 2 is during forward slip, spline slides forwards of the shaft 7 in transmission shaft 6, shaft 7 and transmission shaft 6 one
It is directly in spline connection status, after the position of backrest 2 is fixed, further effectively fixed student's shoulder is needed, rotates at this time
Transmission shaft 6, transmission shaft 6 drive shaft 7 to rotate coaxially, and shaft 7 drives first bevel gear 8 to rotate, and first bevel gear 8 drives second
Bevel gear 9 rotates, and second bevel gear 9 drives lead screw 11 to rotate, and lead screw 11 drives nut 12 along 18 slide downward of guide rail, nut 12
It is fixed with transverse slat 13,13 left and right ends of transverse slat are symmetrically arranged with clamping plate 14, and then 14 slide downward of clamping plate, and 14 upper end of clamping plate is circular arc
The shoulder of student is effectively fixed in shape, and student is made to be in correct posture state, and the sitting posture kept fit is corrected defects of vision, favorably
In the sound development of student, since the connection of 11 nut of lead screw has certain self-locking performance, the position of fixture block, operation letter is effectively fixed
It is single；
When student needs rest, transmission shaft 6 is inverted, first bevel gear 8 drives second bevel gear 9 to invert, the second cone tooth
Wheel 9 drives lead screw 11 to invert, and lead screw 11 drives nut along 18 upward sliding of guide rail, and transverse slat 13 drives fixture block upward sliding, makes to press from both sides
Block and shoulder are detached from, and student can stand up to move freely, and when needing to reset on backrest 2, pawl are pushed aside, in going barrel 16
Under effect, rotation axis 3 is inverted, and curved groove 4 is resetted with movable slider 5, and then backrest 2 slides backward reset on pedestal 1, facilitates reality
With.
The more traditional equipment of the utility model has following benefit: 1) using curve slot structure, and combine going barrel and ratchet
Pawl principle efficiently controls backrest sliding back and forth on pedestal, and has self-locking performance, easy to operate, better reduction, just
In adjusting；2) screw-nut structure is utilized, the upper-lower height of fixture block is effectively adjusted, is conducive to the shoulder of fixed student, correction
