Description
Technical field
This utility model belongs to teaching aid equipment field, specifically a kind of environment friendly blackboard.
Background technology
Blackboard is one of auxiliary equipment conventional in daily teaching, and blackboard is commonly used to traditional instruction content, facilitates student to understand and grasps.But in existing teaching, the content of courses on blackboard typically uses chalk-writing, well known, chalk write with wiping during because chalk bits drop, frequently result in powder to fly upward, not only having influence on daily teaching, cause attention of student not concentrated, quality of instruction is poor, and have a strong impact on the health of student and teacher, it is unfavorable for classroom instruction.So being badly in need of a kind of environment friendly blackboard to solve the problems referred to above.
Utility model content
This utility model provides a kind of environment friendly blackboard, in order to solve defect of the prior art.
This utility model is achieved by the following technical programs:
A kind of environment friendly blackboard, including bracing frame, bracing frame upper mounting plate body, the bottom of plate body connects several casings by fixing bar, casing top arranges charging aperture, the bottom of casing arranges discharging opening, charging aperture connects feed pipe, the top of feed pipe is provided with arc mouth, sliding surface type agnail is arranged on the inside of feed pipe, the top of casing is divided into bellows, the top of bellows arranges fixing seat, the bottom of bellows is provided with electric rotating machine, the both sides of fixing seat arrange screw rod, screw rod coordinates with electric rotating machine, the bottom of screw rod arranges nut, nut is positioned at the bottom of electric rotating machine.
A kind of environment friendly blackboard as above, described bracing frame is hinged with the sidepiece of plate body, and jointed shaft is installed ratchet knob.
A kind of environment friendly blackboard as above, described casing is provided with rule, in order to conveniently to check the volume of casing, it is achieved the different operating pressure of bellows.
The utility model has the advantages that: this utility model arranges several casing, casing is possible not only to for containing chalk powder, and the volume of casing, the operating pressure different to reach bellows can be regulated according to the drying regime of varying environment, thus meet different adsorption effects.Electric rotating machine drives screw motion to realize the up and down motion of bellows, the powder in air is adsorbed by feed pipe, arc mouth effectively increases adsorption area, the sliding surface type agnail arranged, prevent pouring out of powder in adsorption process, reduce chalk writing and the dust from flying phenomenon in wiping process and the suction of chalk powder, ensure student and the health of teacher, improve the quality of teaching to the utmost.This utility model noiselessness, environmental protection, the quality of instruction in daily teaching can be effectively improved, there is good application value.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；Fig. 2 is I partial enlarged drawing of Fig. 1；Fig. 3 is the structural representation of this utility model feed pipe.
Figure number marks: 1 casing, 2 nuts, 3 electric rotating machines, 4 screw rods, 5 bellowss, 6 fix seat, 7 charging apertures, 8 feed pipes, and 9 fix bar, 10 discharging openings, 11 plate bodys, 12 bracing frames, 13 ratchet knobs, 14 agnails, 15 arc mouths.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
A kind of environment friendly blackboard, as shown in the figure, including bracing frame 12, bracing frame 12 upper mounting plate body 11, the bottom of plate body 11 connects several casing 1 by fixing bar 9, casing 1 top arranges charging aperture 7, the bottom of casing 1 arranges discharging opening 10, charging aperture 7 connects feed pipe 8, the top of feed pipe 8 is provided with arc mouth 15, sliding surface type agnail 14 is arranged on the inside of feed pipe 8, the top of casing 1 is divided into bellows 5, the top of bellows 5 arranges fixing seat 6, the bottom of bellows 5 arranges electric rotating machine 3, the both sides of fixing seat 6 arrange screw rod 4, screw rod 4 coordinates with electric rotating machine 3, the bottom of screw rod 4 arranges nut 2, nut 2 is positioned at the bottom of electric rotating machine 3.This utility model arranges several casing 1, and casing 1 is possible not only to for containing chalk powder, and can regulate the volume of casing 1, the operating pressure different to reach bellows 5 according to the drying regime of varying environment, thus meets different adsorption effects.Electric rotating machine 3 drives screw rod 4 motion to realize the up and down motion of bellows 5, the powder in air is adsorbed by feed pipe 8, arc mouth 15 effectively increases adsorption area, the sliding surface type agnail 14 arranged, prevent pouring out of powder in adsorption process, reduce chalk writing and the dust from flying phenomenon in wiping process and the suction of chalk powder, ensure student and the health of teacher, improve the quality of teaching to the utmost.This utility model noiselessness, environmental protection, the quality of instruction in daily teaching can be effectively improved, there is good application value.
