Description
The utility model relates to a kind of teaching-board pen, and particularly a kind of reused teaching-board pen belongs to the stationery field.
At present, most teaching units are also using blackboard and chalk as the classroom instruction instrument, but use chalk to exist dust many, contaminated environment and shortcoming such as unhealthful.Along with the prosperity of science and technology, many units have used the teaching-board pen of the erasable writing that writes on the blank instead, have significantly reduced dust, are subjected to the user and welcome.But because the teaching-board pen that sell the open market is disposable dress ink after water storage cylinder, promptly kill bonnet, ink is with after doing, and water-filling promptly can not muptiple-usely use again.Even pry open bonnet by force, pour out water storage cylinder water-filling again, also can move to cause and cause writing quality to descend because of reloading the back water storage cylinder with a mouth loose contact, and when prying open bonnet little the skidding off easily of water storage and stain clothes and other article.So, the overwhelming majority can only abandon after disposable teaching-board pen used up ink, at this moment writing few situation such as computer floor, message board still can be for the user accepts, but in the teaching of common large, medium and small then because of the cost height, waste is big and be difficult to promote the use of.
The purpose of this utility model provides and a kind ofly overcomes above-mentioned teaching-board pen and can only disposablely use, and wastes bigger shortcoming, can fill ink repeatedly, repeatedly uses, and writes smoothly teaching-board pen with low cost.
The purpose of this utility model is achieved in that at close bonnet 8 places, the rear portion of teaching-board pen, design has in the body 3 of packing into, and the retainer plate 5 of combining closely with a body 3 inwalls, there is water injection hole 7 in the central authorities of retainer plate 5, the effect of retainer plate 5 is fixing water storage cylinder 4, guarantee in that to open bonnet 8 back water storage cylinder 4 unlikely loosening, avoid nib 2 displacements to cause producing the not enough influence of water outlet writing with water storage cylinder 4 loose contacts.When after ink uses up, filling again, ink is splashed into water storage cylinder 4 interior getting final product by water injection hole 7.Open bonnet 8 for convenience, design has salient point 6 on the neighboring of bonnet 8, uses socket wrench specially adapted for it to pin salient point at an easy rate during unlatching and bonnet is pulled out.
Because the utility model has adopted the design that can repeatedly fill ink and guarantee fluent writing, teaching-board pen can repeated multiple times be used, overcome existing teaching-board pen owing to disposable use causes the cost height, wasted shortcomings such as big, be suitable for very much in large, medium and small school and promote the use of.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is can muptiple-use use teaching-board pen structural representation;
Fig. 2 is the bonnet front view.
Body 3 usefulness rigid plastics form; The cap for brush 1, retainer plate 5, the less plastics of bonnet 8 usefulness hardness form, make its can be more tight when combining with a body, coincide; The soft porous nylon of nib 2 usefulness is made, and water storage cylinder 4 is made inner core by sponge, outerly is wrapped to form a cylinder with layer of plastic film.After the ink that fills for the first time uses up, blocking on bonnet 8 neighborings salient point 6 with sleeve pulls out bonnet, with the water injection hole 7 of dropper by retainer plate 5 ink is splashed into standpipe 4 then, owing to when design, retainer plate 5 and a body 3 inwalls are combined closely, make and both guaranteed that standpipe 4 is at will not loosening, guaranteed that again ink can not flow to nib 3 and cause water clock along a body inwall when dripping the dress ink.Salient point 6 on bonnet 6 neighborings evenly distributes on the neighboring, can be 2,3,4,5,6 or more, body 3 cross sections and a body 3 cross section of inboard wall shapes can be that circle or regular polygon, the cap for brush 1, retainer plate 5, bonnet 6 should coincide mutually with the partial shape that a body 3 or a body 3 inwalls are connected mutually, in conjunction with closely.
Embodiment 1: make teaching-board pen by foregoing description, a body 3 and cross section of inboard wall are garden shape, and four salient points 6 evenly distribute on bonnet 8 neighborings.
