Description
Technical field
The present invention relates to intelligence learning equipment technical fields, and in particular to has arrived a kind of multi-functional desk.
Background technology
As the epoch make constant progress, the mankind obtain huge advance in many aspects, such as：Go out in terms of teaching
Multimedia integration classroom is showed, great convenience is brought to teacher's teaching and student's study.It investigates and sample investigation is shown,
84% or more student and teacher are dissatisfied to desk used at present：Student, which thinks to draw, dedicated drawing table and to paint
Figure room carries out, and T-square and drawing tool packet will be carried every time by drawing, and often occurs leaving behind drawing tool in addition and paint
Drawing is fixed loosely and the case where cause to do over again again frequent occurrence when figure；The cleaning of desk drawer is very inconvenient.This external survey
It was found that desk used at present and drawing table, recent decades form are often almost without what big variation of generation, change
The material of desk, most of drawing tables are all can only be horizontal or to tilt and bring very big inconvenience to drawing, also influence the body of student
Body is healthy, three aspects below major embodiment：First, when drawing, most of us' time even All Time will be curved waist,
Eyes also more closely conveniently will smoothly could draw ideal drawing apart from desktop；But it can if things go on like this cause student bow-backed, near-sighted
And cervical vertebra ache.Common drawing desk lacks special drawing tool, and student will also specially take drawing tool before drawing every time.
Since drawing tool is more trifling, often has classmate and leave behind ruler or compasses, return is taken to cause to draw and is not timely completed；
The problems such as drawing, which is fixed, and position line is drawn when drawing can all take a substantial amount of time；Second, distance is smaller between desk, drawer
Inside, which cleans to be inconvenient, to be needed to bend over 90 °, and broom or rag, which are also reached drawer just, to sweep, due to
Sweep it is inconvenient even there is careless cleaning and deal with to get over, or even do not sweep and cause drawer corner accumulate many sundries and
Rubbish；Third, class-exercise, lesson test and draw when, teacher generally reflects that desk function is excessively single, cannot understand in time

Drawing elevating drive mechanism uses：As shown in fig. 7, in use, being closed main air switch QS first, then again together
When by next stage motor rotate forward switch SB1, second-stage electric machine rotating forward switch SB2 so that motor M is rotated forward, to pass through
Gear coupling 103-8 turn spurs 103-7 and rack protection pipe 103-3 inner racks 103-2 engaged transmissions so that level-one table
101 one end of layer assembly is lifted up, and is stopped when the rack movement limit contact block 103-6 of the sides rack 103-2 touches first motor
When travel switch SQ1, first motor stops travel switch SQ1 and motor M is stopped, and 101 one end of level-one table layer assembly carries upwards
Extreme higher position is risen to, is opened when needing the downward adjusting to 101 one end of level-one table layer assembly, while by the reversion of next stage motor
Pass SB3, second-stage electric machine reversal switch SB4 so that motor M is inverted, and straight-tooth is driven to pass through gear coupling 103-8
Take turns 103-7 and rack protection pipe 103-3 inner racks 103-2 engaged transmissions so that 101 one end of level-one table layer assembly to decline, when
The rack movement limit contact block 103-6 of the sides rack 103-2, which touches the second motor, to be stopped when travel switch SQ2 motor M being stopped
Only.
Automatic clearing mechanism uses：As shown in figure 8, in use, closure secondary air switch QS first, then touches multiple again
Close button switch SB1 make its be closed to level-one contactor KM1 coil obtain it is electric, level-one contactor KM1 main contacts be closed to
Driving motor M is driven to rotate forward, to drive ball screw assembly, 202-1 to be driven by transmission coupling 202-4, ball-screw
The feed screw nut ball 202-6 of secondary 202-1 is driven on leading screw 202-7 to side, to drive under feed screw nut ball 202-6
The cleaning component 203 in face is driven, and is cleaned to the forward direction in drawer to realize, as the cleaning fixed handle 203-1 for cleaning component 203
After touching level-one travel switch SQ1, level-one travel switch SQ1 normally-closed contacts will disconnect so that level-one contactor KM1
Coil losing electricity, motor moment stop, and the coil of Secondary contact device KM2 then will it is electric, Secondary contact device KM2 main contacts be closed from
And driving motor M is driven to invert, and to drive ball screw assembly, 202-1 to be driven by transmission coupling 202-4, ball wire
The feed screw nut ball 202-6 of thick stick secondary 202-1 is driven on leading screw 202-7 to the other side, to drive feed screw nut ball
Cleaning component 203 below 202-6 is driven, to realize to the reversed cleaning in drawer, when the cleaning for cleaning component 203 is fixed
After handle 203-1 touches second level stroke switch SQ2, second level stroke switch SQ2 normally-closed contacts will disconnect so that Secondary contact
The coil losing electricity of device KM2, motor M stop, to complete the positive and negative two-way cleaning to drawer, when electric current is more than one section of specified value
After time, circuit its generate heat make fuse FU1 or fuse FU2 Melt moltens, to make circuit disconnect into
Row protection.
The above is the example and explanation of the present invention, but does not mean that the obtainable advantage of the present invention is so limited, all
Being may be to wherein one the advantages of realization in the simple transformation of structure, and/or some embodiments in practice process of the present invention
It is a or it is multiple within the scope of protection of this application.
