Abstract

The utility model relates to a fixed type chalk loader which comprises a barrel body, a lantern ring and a base, wherein the barrel body is of an inverted cone structure of which the upper opening is larger than and the lower opening; the upper half part of the barrel body is composed of two elastic fixing clamps; the lower half part of the barrel body is inserted into the base; the lantern ring is sleeved on the barrel body; the base is of a sucker structure and a barrel sleeve is arranged on the sucker structure. The fixed type chalk loader is novel and unique in design, simple in structure, small and exquisite, flexible, capable of effectively preventing chalks from being broken, convenient, sanitary, wide in application prospect and applicable to most people, especially to teachers.

Description

Fixed chalk loading bin

Technical field

The utility model relates to a kind of instrument, especially a kind of fixed chalk loading bin.

Background technology

Chalk is the instrument that widely uses in the daily life, is for general on the blackboard and writes.The chalk in ancient times is processed with natural chalk usually, but many now material replacements with other.The composition of chalk is a kind of white depositions of calcium sulfate, is not easy to be decomposed, and particle is bigger than dust.Now, the chalk of domestic use mainly contains two kinds of common chalk and dust-free chalks, and its main component is calcium carbonate and calcium sulfate, or contains a spot of calcium oxide.

At present, chalk is used on the school instruction more.But when the teacher write on blackboard, situation about after regular meeting chalk occurs and fractures, can't normally use caused significant wastage; And long-term the contact with chalk can make finger come to harm, and be very unhygienic, makes troubles to people's use.

The utility model content

In order to overcome the chalk frangible and to use antihygienic deficiency, the purpose of the utility model provides a kind of fixed chalk loading bin, and it gets up to use with chalk sleeve, and finger can directly not contact chalk, efficiently solves the problems referred to above.

For the technical scheme that purpose adopted that realizes the utility model is: a kind of fixed chalk loading bin is characterized in that: it is made up of stack shell, the collar, base; Described stack shell is the inverted cone-shaped structure that open upper end is big, lower ending opening is little, and its first half is made up of two rubber-like geometrical clamps, and the latter half is inserted on the base; The described collar is enclosed within on the stack shell; Described base is a sucker structure, which is provided with jacket casing.

The beneficial effect of the utility model is: novel in design unique, simple in structure, small and exquisite flexible, can prevent effectively that chalk from fractureing, and convenient and healthy, have a extensive future, be applicable to most of crowds, especially the schoolman.

1-chalk, 2-geometrical clamp, the 3-collar, 4-stack shell, 5-jacket casing, 6-base among the figure.

The specific embodiment

In Fig. 1, Fig. 2, first embodiment shown in Figure 3, a kind of fixed chalk loading bin, it is characterized in that: it is made up of stack shell, the collar, base; Described stack shell is the inverted cone-shaped structure that open upper end is big, lower ending opening is little, and its first half is made up of two rubber-like geometrical clamps, and the latter half is inserted on the base; The described collar is enclosed within on the stack shell; Described base is a sucker structure, which is provided with jacket casing.

In Fig. 1, second embodiment shown in Figure 2, collar upper surface opening is big, the lower surface opening is little, can slide along stack shell, and sliding to the stack shell upper end to make geometrical clamp clamp chalk; Collar inside contains the material that is magnetic, and can be adsorbed on the blackboard.

In Fig. 1, Fig. 2, the 3rd embodiment shown in Figure 3, base is provided with jacket casing, is used for inserting stack shell; Base can be adsorbed on blackboard or the dais through sucker.

When using the utility model, insert chalk to stack shell, will overlap hoop stack shell upper end and slide, make geometrical clamp clamp chalk, at this moment, grasping stack shell can write; Base is adsorbed on blackboard or the dais, when being convenient to not use stack shell is inserted wherein; After using, also can stack shell directly be adsorbed on the blackboard through the magnetic collar.
