Description
Technical field
The utility model relates to the teaching appliance field, is specially semi-automatic combined type blackboard.
Background technology
The blackboard that uses needs teacher oneself to wipe mostly at present, like this both delays the class period, make decrease in efficiency on class, and chalk dust is too many, has influenced the healthy of teacher and front-seat classmate; Also have blank to sell on the market, though ashless, use cost is high, and the automatic blackboard that has is all used driven by power, like this will increase cost, also has unsafe factor; Automatic blackboard can all be wiped the monoblock blackboard when erasing the board, so just do not meet teacher and classmate's custom on class, general teacher and classmate often get used to only wiping the older content of a part, and the newer content of reservation, such as the time marquis who gives a lesson, some minority content (as theorem, formula etc.) needs to keep whole class and is not wiped, and this existing automatic blackboard can't satisfy.
Summary of the invention
The utility model provides a kind of with low cost just at above technical problem, and can widely used semi-automatic combined type blackboard.
Concrete technical scheme of the present utility model is as follows:
Semi-automatic combined type blackboard, comprise fixedly small blackboard, Reelable blackboard one, Reelable blackboard two, hairbrush, scrape hawk, guide rail, the pull rope guide rail, the awl tooth, collect box, boss, clamp, straight-tooth gear, conical gear, spike, the copper sheathing of trough of belt, clamp, draw-in groove, pull rope, pulley, handle, the upper sheave group, the lower pulley group, shell, sheet rubber and spring leaf, semi-automatic combined type blackboard is fixed on the wall, fixedly small blackboard is arranged on a side of Reelable blackboard one and Reelable blackboard two, hairbrush with scrape hawk and closely contact, at hairbrush with scrape hawk and the upper sheave group is set in the upper end of Reelable blackboard one and Reelable blackboard two, the lower end is provided with the lower pulley group, hairbrush and to scrape hawk fixing on the wall and be placed in the front of Reelable blackboard one and Reelable blackboard two, at the two ends up and down of Reelable blackboard one and Reelable blackboard two guide rail and pull rope guide rail are set, spring leaf is installed in the corner of guide rail, conical gear passes straight-tooth gear by axle and hairbrush is fixed, spike passes the copper sheathing of trough of belt and all passes Reelable blackboard one and the middle part of Reelable blackboard two, clamp slips into along draw-in groove, pull rope moves on pulley, handle passes shell and is connected with the awl tooth, sheet rubber is arranged on the both sides of shell, collects box and is arranged on the lower end of shell and is connected and fixed by boss and clamp and shell.
Reelable blackboard one and Reelable blackboard two are linked to each other by pull rope, realized interlock, when promoting Reelable blackboard for the moment, Reelable blackboard one and Reelable blackboard two are along being similar to the front and back translation earlier of oval track, move left and right again, until transposition, in the process of motion, a Reelable blackboard is wherein cleaned down successively by three cylindric brushes, and the content of another piece Reelable blackboard is then all kept, and three cylindric hairbrush are respectively coarse wool, middle hair and fine, soft fur, can make Reelable blackboard one or Reelable blackboard two pass through coarse wool successively, the scouring one by one of middle hair and fine, soft fur hairbrush is wiped totallyer; Hawk is all scraped in three cylindric hairbrush back; when rotating brush; can the ash on the hairbrush be struck off; the scouring quality can not descended along with adding up of ash; and chalk dust falls into the ash collecting box of below, and the process of whole erasing blackboard is all carried out in the enclosure, and there is the rubber slab of retaining ash the shell both sides; can block chalk dust, protection teacher and classmate's is healthy.
Fixedly small blackboard is artificial scouring, makes teacher more flexible on class, and layout is more reasonable.
Straight-tooth gear can make 3 hairbrush rotate simultaneously, conical gear and the engagement of awl tooth, and gear all adopts big matched in clearance.
Technique effect of the present utility model shows: semi-automatic combined type blackboard does not need electric power to drive, and has both saved cost, and is safe and reliable again, and reasonably layout makes and has more orderliness on class.

The specific embodiment
The utility model is described in further detail below in conjunction with the specific embodiment and Figure of description
Embodiment:
Semi-automatic combined type blackboard is fixed on the wall, fixedly small blackboard is arranged on a side of Reelable blackboard one and Reelable blackboard two, hairbrush with scrape hawk and closely contact, upper end at Reelable blackboard one and Reelable blackboard two is provided with the upper sheave group, the lower end is provided with the lower pulley group, hairbrush and to scrape hawk fixing on the wall and be placed in the front of Reelable blackboard one and Reelable blackboard two, at the two ends up and down of Reelable blackboard one and Reelable blackboard two guide rail and pull rope guide rail are set, conical gear passes straight-tooth gear by axle and middle hairbrush is fixed, the hairbrush of both sides connects straight-tooth gear by axle, and with the engagement of following straight-tooth gear group, spike passes the copper sheathing of trough of belt and all passes Reelable blackboard one and the middle part of Reelable blackboard two, clamp slips into along draw-in groove, pull rope moves in the pull rope guide rail, and pulley is set at the turning, handle passes shell and is connected with the awl tooth, sheet rubber is arranged on the both sides of shell, can avoid chalk dust to blow out, collect box and be arranged on the lower end of shell and be connected with shell with clamp and fix by boss from both sides.
Reelable blackboard one and Reelable blackboard two are linked to each other by pull rope; realized interlock; when promoting Reelable blackboard for the moment; Reelable blackboard one and Reelable blackboard two are along being similar to the front and back translation earlier of oval track; move left and right again; until transposition, in the process of motion, a Reelable blackboard is wherein cleaned down successively by three cylindric brushes; the content of another piece Reelable blackboard is then all kept; hawk is all scraped in the hairbrush back, and clamp is stuck in the draw-in groove, is used to pin straight-tooth gear; hairbrush when moving, Reelable blackboard one and Reelable blackboard two is not rotated; when the cleaning hairbrush, can upwards extract clamp, turning handle out; when rotating brush; can the ash on the hairbrush be struck off, the scouring quality can not descended along with adding up of chalk dust, and chalk dust falls into the ash collecting box of below; the process of whole erasing blackboard is all carried out in the enclosure; and there is the rubber slab of retaining ash the shell both sides, can block chalk dust, and protection teacher and classmate's is healthy.
The length of Reelable blackboard one and Reelable blackboard two is slightly larger than the length at guide rail turning, before translation forward or backward, there is one jiao to be introduced into track earlier, make Reelable blackboard one and Reelable blackboard two form certain inclination angle, being beneficial to translation carries out smoothly, spring leaf on the guide rail can make Reelable blackboard one and Reelable blackboard two along the orbiting motion of determining, be Reelable blackboard one and Reelable blackboard two by on the guide rail during " Y " shape junctions, go among Fig. 7 solid line place or dotted line place by spring leaf and control Reelable blackboard one and Reelable blackboard two respectively by two of " Y " shape mouth different branch's guide rails operations.
