Abstract

The utility model relates to a chalk box of teaching aids, which solves the technical problems that the existing like product is single in structural style, and chalk is easy to clamp at a chalk outlet. The chalk box comprises a box body, a small spring, a pressing plate, a flipping cover, a pushing plate and a large spring and is characterized in that one end inside the box body is connected with the pushing plate through the large spring, the pushing plate is slidingly arranged in the box body, a small chamber is arranged at one end of the bottom of the box body and hinged to the pressing plate, one end of the pressing plate is arranged outside the small chamber, and the other end of the pressing plate is arranged in the small chamber and connected with the bottom of the small chamber through the small spring. A chalk placing opening is arranged on one side of the box body hinged to the pressing plate, the chalk placing opening is hinged to the flipping cover, a chalk outlet is arranged at the top of the box body, and the part of the chalk outlet and the part of the pressing plate arranged in the small chamber are vertically corresponded. The chalk box is simple in structure, convenient to take the chalk and suitable for being used as a teaching chalk box or structural improvement of the like product, and the problem that the chalk is clamped at the chalk outlet is not easy to occur.

Description

Chalk holder

Technical field

The utility model relates to teaching aid, is a kind of chalk holder.

Background technology

Chalk holder is the box that is used to hold chalk, and existing comparatively common chalk holder is to be made with paper material, and is fragile, and comparatively inconvenience of chalk access.For solving this type of problem, some solutions are disclosed in the prior art, Granted publication CN2744623Y as the Chinese patent literature publication, December 7 2005 Granted publication day, utility model title " the automatic chalk holder of hand push type ", the structure that this utility model adopted are that box body one side is provided with the chalk inlet, and another relative side is provided with the position outlet lower than inlet, the exit is provided with the switchboard that is hinged on the box body, is provided with spring below switchboard; The top of box body is provided with the adjusted plate that cooperates with box body two sides slideway, adjusted plate below is provided with the control leaf spring that is fixed on one with it, regulate the box body capacity by regulating the adjusted plate, when hand is pressed switchboard, chalk rolls out from going out the pen mouth automatically, simple, convenient, solved the technical problem that chalk is difficult for taking.Similar to above-mentioned patent, the Granted publication CN201139174Y of Chinese patent literature publication for another example, on October 29 2008 Granted publication day, the utility model name is called " a kind of multi-functional environment-protection chalk holder "; And Granted publication CN201451845U, on May 12 2010 Granted publication day, the utility model name is called " chalk holder automatically ".Above-mentioned three patents all can reach the purpose of the chalk of conveniently taking, but its structural style is single, are prone to the problem that many chalks are stuck in out the pen mouth.

Summary of the invention

For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of chalk holder that makes things convenient for chalk to take to this area, and it is single to make it solve existing like product structural style, is prone to the technical problem that chalk is stuck in out the pen mouth.Its objective is and be achieved through the following technical solutions.

A kind of chalk holder, this chalk holder comprise box body, little spring, pressing plate, renovate, push pedal, big spring; Its structural design main points are that an end connects push pedal by big spring in the described box body, push pedal places in the box body and slides, one end of described box body bottom is provided with loculus, loculus hinged platen, pressing plate one end place the loculus outside, and the other end places in the loculus and connects the loculus bottom by little spring, one side of described box body hinged platen is provided with puts the pen mouth, put pen mouthful hinged renovating, described box body top is provided with out pen mouthful, and pressing plate places part in the loculus with described to go out pen mouthful vertical corresponding.By pushing pressing plate, pressing plate supports chalk for described and goes out pen mouthful, thereby makes things convenient for the operation of taking of chalk.Because chalk is the thrust that relies on pressing plate from going out that pen mouth stretches out, so do not exist chalk to be stuck in out the problem of pen mouth.

By at least one group of described box body, little spring, pressing plate, renovate, push pedal, big spring constitute described chalk holder.Described box body side is provided with magnet, magnetic conductor.By this structure, make a plurality of box bodys can constitute an integral body mutually, make things convenient for the operation of taking of different colours chalk.

Described push pedal top is provided with to push away to be turned round, and described box body top is provided with and pushes away turns round the chute that is slidingly matched.Push away the position of turning round that makes things convenient for the manual adjustments push pedal that is provided with, thereby make things convenient for chalk to put into box body.

The utility model is simple in structure, and chalk is taken comparatively convenient, and is not prone to the problem that chalk is stuck in out the pen mouth, and be suitable as the teaching chalk holder and use, or the architecture advances of like product.

The specific embodiment

Now in conjunction with the accompanying drawings, the utility model is further described.Among the figure name of sequence number be called box body 1, loculus 101, put pen mouthfuls 102, go out pen mouthfuls 103, chute 104, little spring 2, pressing plate 3, renovate 4, chalk 5, push pedal 6, push away turn round 601, big spring 7.

Fig. 1 is as embodiment one, this chalk holder comprises box body 1, little spring 2, pressing plate 3, renovate 4, push pedal 6, big spring 7, and box body internal diameter one end connects push pedal by big spring, and the push pedal in the box body is slided and placed in the box body, the box body other end is provided with puts pen mouth 102, puts pen mouthful hinged the renovating in upper end.The pen mouthful downside of putting at box body is provided with loculus 101, the loculus hinged platen, and pressing plate one end places in the loculus and by little spring and connects the loculus bottom, and the pressing plate other end stretches out in outside the loculus.The top of box body is provided with out pen mouthfuls 103, and pressing plate places part in the loculus with to go out pen mouthful vertical corresponding.

Fig. 2 is that the structure of push pedal among Fig. 1 is improved as embodiment two.Push pedal is provided with the top is made as to push away and turns round 601, be provided with and push away at the box body top and turn round the chute 104 that is slidingly matched, turn round, regulate the position of push pedal, make things convenient for chalk to put into box body by pushing away.

Fig. 3, Fig. 4 are respectively the expansion structures of Fig. 1, Fig. 2, mainly be with the structure of Fig. 1, Fig. 2 respectively permutation and combination become a row form, thereby constitute new integral body, this kind integral body makes things convenient for depositing and taking of different colours chalk.The mode of permutation and combination can be fixed thereby adjacent two box bodys are adsorbed by in the box body side magnet and magnetic conductor being set, and this kind structure is combined and instant not only, and is convenient to dismounting.Certainly, also the utility model directly can be made into Fig. 3, overall structure shown in Figure 4, to reach well-set purpose.
