Abstract
The utility model relates to a teaching blackboard facilitating university advanced mathematics drawing. The blackboard aims at solving the problem that the existing blackboard is small in size, teachers need to hold an eraser by the hand to erase the blackboard, in additional, when teachers for the advanced mathematics major write on the blackboard, the teachers need to draw various function curves by the hand beside figures and characters, and a plurality of class time is occupied. The blackboard comprises a blackboard main body (1) which comprises an outer frame (2). A writing board (3), a light-emitting grid board (4) and a base plate (5) are embedded in the outer frame. An erase is installed in sliding grooves (6) of the upper frame and the lower frame of the outer frame. A light source management device (8) is installed on the upper portion of the blackboard main body through an L-shaped support, and T-shaped support legs (9) with universal wheels are installed on the lower portion of the blackboard main body. The light-emitting grid board comprises an insulation board (11) and light-emitting grids (12) installed on the insulation board (11). The blackboard is applied to advanced mathematics.
Description
technical field:
the utility model relates to a kind of blackboard for education that facilitates university's higher mathematics to draw.
background technology:
the blackboard for education using in existing university classroom is arranged to surface area for 4.2m
2
left and right, this is the number of times erasing the board on teacher's class in order to reduce, when common break, student helps teacher to erase the board.So also there are a lot of compound sliding glass blackboards, to reduce body of wall space that large area blackboard takies and the amplitude of writing of teacher's arm, because the volume of existing blackboard eraser is very little, needed hand-held blackboard eraser obliterating person's handwriting.In addition, when higher mathematics professional teachers is write writing on the blackboard, except numeral, word, also need to draw various function curves, teacher's free-hand drawing takies the time on a lot of classes.
summary of the invention:
the purpose of this utility model is to provide a kind of blackboard for education that facilitates university's higher mathematics to draw.
above-mentioned object realizes by following technical scheme:
a kind of blackboard for education that facilitates university's higher mathematics to draw, its composition comprises: blackboard main body, described blackboard main body comprises housing, insert clipboard, luminous lattice plate and base plate in described housing, and blackboard eraser is slidably installed in the chute of the upper ledge of described housing, lower frame; Light source management devices is installed by L bracket in described blackboard main body top, and described blackboard lower body part is installed T shape supporting leg, and one group of universal wheel is installed in described T shape supporting leg bottom; Wherein, described luminous lattice plate comprises the luminous lattice of installing on insulation board and described insulation board, and described luminous lattice connect described light source management devices.
the described blackboard for education that facilitates university's higher mathematics to draw, described light source management apparatus surface also has power key and touching display screen, and described light source management devices inside has microcomputer, battery and brightness regulating apparatus.
the described blackboard for education that facilitates university's higher mathematics to draw, described blackboard eraser also comprises support bar, and a side of described support bar is installed cavernous body, and roller is installed by leg in described support bar two ends, and described roller is arranged in described chute.
the described blackboard for education that facilitates university's higher mathematics to draw, described clipboard is Glass blackboard or writing whiteboard.
the described blackboard for education that facilitates university's higher mathematics to draw, described luminous lattice are one group of LED bulb or LED fluorescent tube.
the beneficial effects of the utility model:
1. the blackboard for education main body of the utility model setting comprises three layers, be respectively clipboard for writing font, can show luminous lattice plate and the base plate of lines, in the time that higher mathematics professional teachers need to be drawn parabola, circle or other function curves, can show needed figure by luminous lattice plate, input by the touching display screen on the light source management devices at blackboard main body top, transfer out the functional digraph of microcomputer storage inside, facilitate teacher to draw and explain knowledge point, avoid drawing and taking limited instructional blocks of time on teacher's class.
2. the blackboard eraser that the utility model being provided with can be slided in blackboard body front end, blackboard eraser two ends have roller, roller rolls in the chute of the upper and lower frame of housing, while utilizing the blackboard eraser of this rolling to erase the board, do not need hand-held, and because the lower-upper length of cavernous body, support bar is corresponding with the width up and down of blackboard main body, so the speed of blackboard wiping clipboard is fast, effective.
brief description of the drawings:
accompanying drawing 1 is external structure schematic diagram of the present utility model.
accompanying drawing 2 is that the utility model is at the structural representation of dismantling after clipboard.
detailed description of the invention:
