Description

The hand-written apparatus of braille

Technical field

The utility model relates to a kind of blind person's stationery, a kind of more precisely apparatus of being convenient to blind person's Hand writing braille.

Background technology

The literal that present blind person generally uses is with the braille of six salient points as basic structure, need during Hand writing by special some letter stencil and braille pen, the used some letter stencil of blind person is mainly the retrography plate at present, need " retrography is just touched ", this brings many inconvenience for writing of blind person, to this, Chinese patent CN03207179.5 just discloses a kind of " the manual braille apparatus of just writing ", it is just being write and is being distributed with some groups of salient points on the base plate, leave appropriate gap between salient point end and the writing window edge, the window place of writing of cover plate has with just to write every group of salient point quantity of base plate identical, and the gathering sill of the separate window left and right sides, the nib of writing pen is a hollow form, the nib inner end diameter is just write though this writing appliance has been realized braille greater than the salient point external diameter of positive writing board, but still has following defective: 1, braille needs special with paper and costs an arm and a leg; 2, because braille is a braille paper is squeezed and at the salient point that face forms, therefore is afraid of tide, is afraid of extruding, the especially beginner touch of can subconsciously exert oneself, easily salient point is touched flat; 3, serviceable life short, can not long preservation; 4, can only write by single face, cause serious waste; Need take anti-pressure measure when 5, posting and preserving, bound books are generally all very thick very heavy.

The utility model content

At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of hand-written apparatus of novel braille simple in structure, easy to use.

For achieving the above object, the technical solution adopted in the utility model is:

The hand-written apparatus of a kind of braille, comprise braille pen and put letter stencil, braille pen is made up of the hollow nib and the hollow penholder that are interconnected, be equipped with in the penholder and write raw material, be provided with the discharging pen core in the nib, the some letter stencil is formed in that a side is hinged by Hinge mechanism and base plate by cover plate, base plate is a flat board, cover plate is provided with the some groups of windows of writing with certain depth, respectively writes on the bottom surface of window and offers the braille through hole, braille through hole and write between the edge of window and leave suitable spacing.

The front end inner chamber of described nib is tapered, pen core and back pen core two parts before pen core divides, preceding pen core end is protruding from nib hole, has the conical surface that seals mutually with the nib conical internal cavity on it, back pen core is resisted against on the preceding pen core by the spring of afterbody, and the spring other end is resisted against on the interior supporting construction of penholder.

Described penholder inner chamber is divided into left and right two chambers by a baffle plate, the raw material of writing that is used to mix use is housed respectively in each chamber, the baffle plate bottom has the hollow cylinder that is used to install the pen core spring, and back pen core is provided with and the corresponding closed flaps body of left and right cavity bottom opening.

The bottom opening of the left and right chamber of described penholder is conical surface shape, and the shape of closed flaps body is corresponding with it.

Offer the raw material hole of up/down perforation on the described closed flaps body.

Also be provided with the scraper that is used to strike off blind spot on the described penholder.

Described scraper is installed in the inside of penholder by the elastic telescopic structure.

The utility model in use earlier with common writing paper clamping between the cover plate and base plate of a letter stencil, nib with braille pen probes in the braille hole along writing window then, push pen core then, at this moment, the spring pressurized, raw material just outwards overflows by the annulus of pen core and nib, and in the braille hole, solidify rapidly, form the blind spot of projection, after starting writing, the preceding pen core conical surface and nib inner conical surface compress closure, and raw material had both stopped outflow.

The utility model makes can realize that not only the front writes; and tow sides all can be write; the blind spot that is formed by chemical raw material combines with paper firmly; be not afraid of extruding, be not afraid of humidity, heavily fortified point is durable for a long time; need not to take special safeguard measure; can select the paper or the cloth of high, medium and low shelves for use according to the value of books and periodicals with paper, not be subjected to the restriction of existing braille dedicated paper.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1--handle 2--nib

Pen core behind the pen core 4--before the 3--

5--spring 6--baffle plate

7--hollow cylinder 8--closed flaps body

9--raw material hole 10--elastic telescopic structure

11--scraper 12--cover plate

13--Hinge mechanism 14--base plate

15--writes window 16--braille through hole

As Fig. 1, Fig. 2, braille pen shown in Figure 3, this braille pen is made up of the handle 1 and the nib 2 of spheroidal, nib 2 is installed in the front end of handle 1, both are hollow-core construction and connect mutually, the front end inner chamber of nib 2 is tapered, pen core 3 and back pen core 4 two parts before pen core divides, the end of preceding pen core 3 is protruding from nib hole, has the conical surface that seals mutually with the nib conical internal cavity on it, back pen core 4 is resisted against on the preceding pen core 3 by the spring 5 of afterbody, spring 5 is installed in the hollow cylinder 7 of baffle plate 6 bottoms, baffle plate 6 is divided into a left side with the penholder inner chamber, right two chambers, the different raw materials of writing is housed in each chamber, back pen core 4 is provided with and a left side, the corresponding conical surface closed flaps of the cone-shaped opening body 8 of right cavity bottom, offer the raw material hole 9 of up/down perforation on the closed flaps body 8, so that the lobe body is during by jack-up, raw material outwards flows out and fully mixes.As shown in Figure 4, the afterbody of handle 1 is equipped with scraper 11 by elastic telescopic structure 10, the time spent can be by turning round and stretching out the hand in the handle, again its ejection both can during use, the size of scraper 11 is advisable can enter blind spot, is convenient to the salient point of a mistake is wiped off, certainly, the device that the salient point of wrongly writing can be aspirated also can be installed, play the effect of erasing rubber.
