Abstract
The utility model discloses a kind of teaching blackboard, be made up of plate body, blackboard eraser, line lattice lamp, have plate body frame around described plate body, plate body frame upper and lower side is provided with upper hopper chute and gliding groove; Described blackboard eraser is the microscler blackboard eraser contour with plate body frame, and two ends are provided with pulley and embed chute; Described line lattice lamp comprises x wire lattice lamp and vertical line lattice lamp, and x wire lattice lamp is evenly arranged on the left of plate body frame or right side, and vertical line lattice lamp is evenly arranged in plate body frame upper end.Utilize the utility model can form four line lattice, five line lattice, matts, coordinate grid, form etc., line compartment distance, brightness, Qu Yu Zhuo is adjustable, and blackboard eraser can be wiped clean the whole space of a whole page fast and chalk dust can be prevented disorderly to fly.
Description
Technical field
The utility model belongs to teaching equipment technical field, especially a kind of teaching blackboard.
Background technology
At present, blackboard is the teaching equipment of schools of various levels and categories' indispensability, the object arranging blackboard is to write and painting as paper-sample, write or paint all require smooth vertical and horizontal, in paper-line lattice, four line lattice, five line lattice, matts, coordinate grid is all in order to smooth vertical and horizontal and arrange, and existing blackboard does not just have similar setting, in teaching, frame effort is time-consuming, and frame does not lack again attractive in appearance.Blackboard needs often to wipe clean the whole space of a whole page because of every class subject difference in addition, and traditional blackboard is wiped and not only required great effort but also time-consuming, and causes chalk dust to fly upward, and is detrimental to health.
Summary of the invention
Lack the problem of line lattice to solve existing blackboard, overcome the slow and air-polluting deficiency that traditional blackboard is wiped, the utility model provides a kind of teaching blackboard, and it can meet each subject to the different requirement of line lattice, can also wipe soon with dust-proof simultaneously.
The technical scheme that the utility model adopts is: a kind of teaching blackboard, and be made up of plate body, blackboard eraser, line lattice lamp, it is characterized in that: have plate body frame around described plate body, plate body frame upper and lower side is provided with upper hopper chute and gliding groove; Described blackboard eraser is the microscler blackboard eraser contour with plate body frame, and two ends are provided with pulley and embed chute, and centre is pedestal, and pedestal is implanted with hairbrush, and hairbrush is uniformly across dust suction sponge, and periphery is provided with the flexible glue skin a little less than hairbrush; Described line lattice lamp comprises x wire lattice lamp and vertical line lattice lamp, x wire lattice lamp is evenly arranged on the left of plate body frame or right side, vertical line lattice lamp is evenly arranged in plate body frame upper end, each line lattice lamp is made up of weak high light gauge tap, concave mirror, LDE lamp, loophole, LDE lamp is arranged in the focus of concave mirror, loophole is close to plate body, and as preferably, loophole is yellow transparent body.
The utility model beneficial effect is: be used alone x wire lattice lamp and can form four line lattice, five line lattice ,-line lattice, can meet phonetic, English, music and each subject demand; Use x wire lattice lamp and vertical line lattice lamp can form matts, coordinate grid, network lattice, form simultaneously, the subject demands such as Chinese language, mathematics, the fine arts can be met; Use switch adjustable nodel line compartment distance; Use weak high light can meet line lattice high request, as: four line lattice can use three weak-high light, reference axis uses high light, looks for coordinate points to use the low light level; The focus that LDE lamp is arranged on concave mirror appears light straight and bright; Yellow loophole appears gold-tinted not easily with chalk stroke is mixed mutually and penetration power is stronger; Pull blackboard eraser to move around on blackboard and can wipe clean the whole space of a whole page easily, fast; Dust suction sponge on blackboard eraser and periphery flexible glue skin prevent chalk dust disorderly to fly; Blackboard eraser also has and blocks the effect of x wire lattice lamp wiring, and x wire lattice can be made to control in-Ding region.

Fig. 3 is the utility model line lattice modulated structure schematic diagram.
Detailed description of the invention
Be described further the utility model below in conjunction with accompanying drawing: a kind of teaching blackboard, be made up of plate body 4, blackboard eraser 3, line lattice lamp 8, it is characterized in that: have plate body frame 5 around described plate body 4, plate body frame 5 upper and lower side is provided with upper hopper chute 2 and gliding groove 6; Described blackboard eraser 3 is the microscler blackboard eraser contour with plate body frame 5, and two ends are provided with pulley 1 and embed chute 2 and 6, and centre is pedestal 13, pedestal 13 is implanted with hairbrush 11, and hairbrush 11 is uniformly across dust suction sponge 12, and periphery is provided with the flexible glue skin 10 a little less than hairbrush 11; Described line lattice lamp 8 comprises x wire lattice lamp 7 and vertical line lattice lamp 9, x wire lattice lamp 7 is evenly arranged on the left of plate body frame 5 or right side, vertical line lattice lamp 9 is evenly arranged in plate body frame 5 upper end, each line lattice lamp 8 is made up of weak high light gauge tap 17, concave mirror 16, LDE lamp 14, loophole 15, LDE lamp 14 is arranged in the focus of concave mirror 16, loophole 15 is close to plate body 4, and as preferably, loophole 15 is yellow transparent body.
The utility model is operation like this: when needs four line lattice, five line lattice ,-line lattice, turn on the weak high light switch 17 of x wire lattice lamp 7; When needs matts, coordinate grid, network lattice, form, turn on the weak high light switch 17 of x wire lattice lamp 7 and vertical line lattice lamp 9 simultaneously; When the outstanding a certain light of needs, the weak high light switch 17 of this light corresponding line lattice lamp 8 is transformed into high light; When needs line compartment distance, turn off corresponding line lattice lamp 8; When not needing x wire lattice to expire version, blackboard eraser 3 being moved to and needs on position; When whole space of a whole page letter written with chalk dried by needs, pull blackboard eraser 3 back and forth.
Claims (2)
