Since 1AB + e > 1BC, the mechanism is a rocker-slider mechanism.

The movement amount of the nut is 3mm and the thread part of the screw rod is 165mm in total every time the handle rotates for one circle, so that the rotation of the inclined plane of the desk can be completed by 27.5 circles;

according to the sitting posture habit and the space occupancy rate of people, the warning lamp is arranged on the left side of the desktop, and the upper position and the lower position (different according to the height of people) of the lamp can be adjusted in a stepless mode. The sensing area is adjusted to 95mm according to the width of the table and the extension of the rod;

use of: when in class (or study), the bracket for supporting the inductor is rotated 90 degrees anticlockwise, then the height of the inductor is adjusted according to the height of the inductor (the optimal position of a person from a table top is 33cm away from the table top), and when the inductor is not used, the bracket for supporting the inductor is rotated 90 degrees clockwise, so that the space range is reduced and the inductor is prevented from being damaged;

the desktop consists of two parts, namely a fixed flat plate surface and a movable plate surface, and the adjustable panel is used for writing and a region for placing books; the fixed plate surface is used for supporting the elbows and is a main supporting force area, and the fixed flat plate surface mainly has two functions: firstly, the fixed flat surface is used for supporting arms, and when people read books and study, the elbow and the arm are naturally and flatly placed on the fixed flat surface, so that the tension and the ache of shoulders and arms are avoided. Second, the fixed plate surface also prevents objects placed on the table from sliding down to the ground.

The inclination angle of the movable board surface is adjustable, stepless adjustment can be realized through the combined mechanism, the requirements on different states of the desktop are met, the neck is ensured to be in a natural straightening state when people read and learn books, the cervical vertebra is prevented from being straightened due to physiological curvature, strain hyperplasia and the like caused by fatigue bending, and the multifunctional desk is particularly suitable for people with pathological changes of the cervical vertebra;

the extension plate can reduce the space for placing, is mainly considered to have wide application, can be used for placing various table articles (books, stationery boxes, water cups and the like), can move at any position on a table surface according to requirements, is convenient to use in a magnetic attraction mode;

1. work stroke (table top up); when the handle is rotated anticlockwise, the screw rod and the handle rotate together to drive the nut to move forwards, and then the rocker is moved upwards through the four-bar mechanism, so that the table top is lifted along with the rocker.

2. And (3) return stroke: when the handle is rotated clockwise, the screw drives the nut to move backwards, the rocker is driven to move downwards through the four-bar mechanism, and the desktop swings flatly along with the rocker.

1. The sliding block of the rocker sliding block mechanism drives the connecting rod to swing for the driving part, and the connecting rod swings to drive the side link to be driven so as to realize the function of inclining the desktop.

2. The self-locking function of the screw mechanism can realize the positioning function of any position of the inclination angle of the desktop.

The utility model has simple and reasonable structural design, realizes the stepless adjustment of the inclination angle of the desktop by adopting the serial combination mechanism of the spiral mechanism and the rocker sliding block mechanism, and has simple structure, convenient processing, low manufacturing cost and convenient processing; the desktop consists of a movable board surface and a fixed flat board surface with adjustable inclination angles; the sitting posture inductor has a good function of preventing myopia of teenagers; the folding plate can reduce the space for placing, thereby bringing great convenience for learners; the book blocking plate is placed at any position of the inclined desktop, so that learners can better select the position of a book on the desktop, and the learners can read the book more conveniently and freely. The desk has the advantages of simple structure, convenient operation, low manufacturing cost, economy and practicality, is suitable for mass study groups, is particularly suitable for being used as a desk for students in classrooms, is also a preferred choice for an ideal desk of a group suffering from cervical spondylosis, and has good market popularization value.
