Abstract

The invention relates to a chalk box for semi-automatically discharging chalks. The chalk box comprises a box body, a box cover, a rotating shaft, a baffle, a long spring, a short spring, a chalk discharging port and a rubber cushion, and is characterized in that the rotating shaft is arranged at the position, which deviates from the middle lower part, of one side of the box body; a chalk outlet is formed at the bottom of one side opposite to the rotating shaft in the box body; one end of the baffle is connected with the rotating shaft, and the other end of the baffle stretches out of the chalk outlet; the baffle can rotate around the rotating shaft; the long spring and the short spring are arranged on the inner side of the bottom of the box body; the box cover is opened, so that people can put chalks into the box body; the chalks are positioned on the upper part of the baffle; and the chalks are positioned on the upper part of the chalk outlet in a static state due to the supporting function of the long spring and the short spring, and when people need to take the chalks out of the box body, only the baffle is required to be pressed; and meanwhile, the rubber cushion is arranged on the outer side of the bottom of the box body. The chalk box is simple in structure and easy to manufacture.

Description

A kind of S. A. goes out the chalk holder of chalk

Technical field

The present invention relates to a kind of chalk holder, more precisely is the chalk holder that a kind of S. A. goes out chalk.

Background technology

Chalk is a very important part in present people's daily life, the teacher needs to use chalk to state the own content of being said at the blackboard top panel when giving lessons to the student, so that the student has more deep understanding, chalk often is placed on the chalk holder the inside, the chalk holder major part of using all is a papery now, just damage easily after using a period of time, and people will open the lid of chalk holder when taking chalk earlier at every turn, and then reach for, it is cumbersome so also to seem, in order to solve the problem that the common flour pencil box damages easily, can produce a kind of wooden chalk holder replaces, in order to solve the problem that the lid that all will open chalk holder removes to take chalk at every turn, can produce a kind of S. A. chalk holder, make people only need carry out shirtsleeve operation and just can from chalk holder, take out chalk, simultaneously, because chalk is more crisp, if place the fracture that chalk holder is easy to cause chalk in the chalk holder because of carelessness, will use chalk to bring very big inconvenience to us like this, in order to address this problem, can produce a kind of chalk holder with the effect of bradyseism shatter-resistant.

In sum, a kind of later-model chalk holder of necessary production is to solve the above-mentioned defective of existing in prior technology.

Summary of the invention

The purpose of this invention is to provide the chalk holder that a kind of S. A. simple in structure, easy to use goes out chalk.

Purpose of the present invention can realize in the following manner: a kind of S. A. goes out the chalk holder of chalk, comprise box body, lid, turning cylinder, baffle plate, long spring, short spring, go out chalk mouth and rubber mount, the position that it is characterized in that a lateral deviation middle and lower part of box body is provided with turning cylinder, the bottom of the one side relative with turning cylinder is provided with out the chalk mouth in box body, one of baffle plate is connecting turning cylinder, stretch out from going out the chalk mouth other end, and the baffle plate moving axis that can rotate rotates, installed inside in the box body bottom has long spring and short spring, open the lid, people just can put into chalk in box body, chalk all is positioned at the top of baffle plate, and because the supporting role of long spring and short spring makes it be positioned at the top of powder delivery pen mouth under static state, only need push baffle plate when people need take out chalk from box body gets final product, simultaneously, box body and lid all are to be formed by the wood materials manufacturing, the outside in box body bottom is equipped with rubber mount, even people fall because of carelessness and run into box body and be unlikely to also to make that most chalk ruptures in the box body like this.

The present invention compared with prior art has following advantage: owing to adopt chalk holder is designed to the structure that S. A. goes out chalk, so just can be convenient for people to take out chalk from chalk holder; Owing to adopt in the bottom of chalk holder rubber mount be installed, so just can reduce the phenomenon of the chalk appearance fracture in the chalk holder to a great extent.

Description of drawings

Accompanying drawing 1 is a structural representation of the present invention.

Among the figure: 1, box body; 2, lid; 3, turning cylinder; 4, baffle plate; 5, long spring; 6, lack spring; 7, go out the chalk mouth; 8, rubber mount.

The specific embodiment

As follows with reference to accompanying drawing 1: a kind of S. A. goes out the chalk holder of chalk, comprise box body 1, lid 2, turning cylinder 3, baffle plate 4, long spring 5, short spring 6, go out chalk mouth 7 and rubber mount 8, the position that it is characterized in that a lateral deviation middle and lower part of box body 1 is provided with turning cylinder 3, the bottom of the one side relative with turning cylinder 3 is provided with out chalk mouth 7 in box body 1, one of baffle plate 4 is connecting turning cylinder 3, stretch out from going out chalk mouth 7 other end, and can rotate moving axis 3 of baffle plate 4 rotates, installed inside in box body 1 bottom has long spring 5 and short spring 6, open the lid 2, people just can put into chalk in box body 1, chalk all is positioned at the top of baffle plate 4, and because the supporting role of long spring 5 and short spring 6 makes it be positioned at the top of powder delivery pen mouth 7 under static state, only need push baffle plate 4 when people need take out chalk from box body 1 gets final product, simultaneously, box body 1 and lid 2 all are to be formed by the wood materials manufacturing, the outside in box body 1 bottom is equipped with rubber mount 8, even people fall because of carelessness and run into box body 1 and also be unlikely to make most chalk fracture in the box body 1 like this, the present invention is simple in structure, is easy to make.

The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
