One small lifter plate, first baffle, the second small box, the second small lifter plate, second baffle and desktop, so when student uses this hair
When bright, the present invention can be adjusted according to stature, student first unscrews big positioning screw, then turns to big rotating disk
Dynamic, big rotating disk drives gear wheel to be rotated by rotary shaft, and gear wheel band moving tooth plate is moved upwards, and spine plate is transported upwards
Pawl can be pushed to be moved forward when dynamic, to tooth plate and spine strip moves bottom plate and large lift plate is moved upwards, greatly
Lifter plate can slide up and down in the first big babinet, and bottom plate is small by the second small box and the drive first of the first small box
Lifter plate, first baffle, the second small lifter plate and desktop are moved upwards together, and are adjusted to suitable position, are then stopped
Rotation to big rotating disk, at this time pawl the first spring elastic force effect under spine board can be lived, to facilitate student will
Big positioning screw is tightened, and firmly fixes the present invention, the student of different statures is facilitated to use, be conducive to that student is allowed to protect
Correct sitting posture is held, is conducive to the health of student, while when student needs to pick and place article, desktop can be moved upwards,
Desktop drives the first small lifter plate and the second small lifter plate to be moved upwards, and the first small lifter plate and the second small lifter plate can
It is slided in the first small box and the second small box respectively, to which student can be in the first small box, the second small box, the
Article is picked and placeed in the space that one baffle and second baffle are surrounded, after picking and placeing, desktop is moved downwards, desktop drives
First small lifter plate and the second small lifter plate are moved downwards, to by the first small box, the second small box, first baffle and
The space that second baffle is surrounded covers.
Because further including having support plate, slide plate, nut, lead screw, bearing block, the first big bearing and small rotating disk, work as
When student needs to pick and place article, small rotating disk can be rotated, small rotating disk drives nut to be moved by lead screw, spiral shell
Mother drives support plate to move upwards by slide plate, since the rear wall of slide plate can only move up and down in sliding slot, institute
Nut can be constrained with slide plate, prevent nut from being rotated with lead screw, to which slide plate drives desktop by support plate
It is moved upwards, article is picked and placeed convenient for student, operate simpler convenience.
Because further including having the first belt pulley, the second belt pulley, first circulation belt, connecting shaft, the second largest bearing and fan
Leaf can drive the first belt pulley to be rotated, the first belt pulley passes through so when student needs to pick and place article by lead screw
First circulation belt drives the second belt pulley to be rotated, and the second belt pulley drives flabellum to be rotated by connecting shaft, flabellum
It, can be by first circulation belt from the first belt when not needing pectinid cooling to carry out pectinid cooling to the leg of student
It is removed on wheel and the second belt pulley, it is easy to use.
Because further including having third belt pulley, the 4th belt pulley, second circulation belt and electric rotating machine, when student needs
When being adjusted to the present invention, electric rotating machine can be started and operated, electric rotating machine drives the 4th belt pulley to be rotated,
4th belt pulley drives third belt pulley to be rotated by second circulation belt, and third belt pulley drives canine tooth by rotary shaft
Wheel is rotated, and to replace manual hand manipulation using electric rotating machine, operation is simpler, and adjustment is more convenient, saves
Shi Shengli.
Because further including having block, the second T-bar, guide pad and second spring, when student rises the present invention
When falling tone is whole, block can be pressed downwards, then big T-bar is pulled along, big T-bar band pawl is moved out of spine plate
Going out, then unclamps the pressing to block, block can keep pawl to be detached from spine plate at this time to upwards block big T-bar,
To facilitate adjustment, when needing to live spine board by pawl, block can be pressed downwards, thus by big T-bar
It unclamps, big T-bar band pawl carries out movement reset backward, then unclamps the pressing to block, and block will be kept off in big T-bar
Front prevents the maloperation to big T-bar, causes the present invention to tamper up and down, performance is more safe and reliable.
（3）Advantageous effect
A kind of adjustable type desk for teaching provided by the present invention, flexible structure can carry out lift adjustment, Neng Gouman
The student of foot difference stature uses, and performance safety is reliable, compact-sized save space, is conducive to that student is allowed to keep correct sitting posture, has
Simple in structure conducive to the health of student, easy to use, repair easy to maintain, maintenance and repair is at low cost, is easy production system
It makes, manufacturing cost is low, and application easy to spread has a wide range of application.
