CN203762478U - Chalk box - Google Patents

Abstract

The utility model discloses a chalk box. A three-dimensional space defined by a shell is divided into a plurality of parallel strip-shaped spaces, wherein the diameter of the chalk is 1.5 times the widths of the strip-shaped spaces by partitioning plates, wherein chalk with different colors can be piled into L-shaped carts inside the strip-shaped spaces; the chalk is arranged in a single row. When chalk with one color is definitely needed, people can push the cart to take out the chalk from the shell, and then the chalk box is convenient to use.

Description

A kind of chalk holder

Technical field

The utility model relates to box field, relates in particular to a kind of chalk holder.

Background technology

In existing teaching, chalk is conventional educational aid, when sale, chalk is placed in box by vertical bar, because chalk length is consistent, make to take at the beginning very inconvenient, use after a period of time, again because chalk quantity reduces, chalk lodging, often the chalk of required color is buried by other color chalks.Convenient in order to allow chalk take, prior art has proposed a lot of improvement to chalk holder, be similar to China Patent No.: 201320198386.2 disclosed technology, the characteristic that chalk holder generally utilizes chalk self gravitation and cylinder to roll, roll out chalk by pressing plate control exit, be similar to the operation principle of pipette box or chopstick box.Although the method is easy, the problem existing is apparent, and first chalk, by crowded in cavity, produces too much friction and collision, easily broken and generation dust; Secondly,, when actual use chalk, need the chalk of different colours, but this equipment is because rolling out of chalk is random, and the chalk of required color obviously can not need to be provided according to user.

Utility model content

The utility model is in order to solve prior art problem, and design one can need to be obtained chalk according to color, and the chalk chalk holder easily of taking.

The technical solution of the utility model is: a kind of chalk holder, comprise shell, and the solid space that shell surrounds is divided into polylith side by side by dividing plate, and width is less than the bar shaped space of 1.5 times of chalk diameters, has the go-cart of one " L " type in bar shaped space.

Preferred as one, the base inner surface of shell is the inclined plane that has certain inclination angle with horizontal plane, and backboard place inner surface and the base inner surface of shell are 90 degree, and inclination angle is the intersection place at backboard and base.

Preferred as one, inclination angle is 15～30 degree.

Preferred as one, go-cart is slided in bar shaped space by pulley.

Preferred as one, in outer casing base, also have dust suction cloth or storage dirt space.

Preferred as one, dividing plate is to separate solid space by slot.

Preferred as one, go-cart has shifting block, and described shifting block stretches out shell.

In sum, the beneficial effects of the utility model are:

1, the solid space that shell surrounds is divided into polylith side by side by dividing plate, and width is less than the bar shaped space of 1.5 times of chalk diameters, and " L " type go-cart in this bar shaped space can be stacked the chalk of color of the same race, and chalk is single.When determine need to this color chalk, can promote go-cart, chalk can be stretched out to shell, take conveniently.

2, the base inner surface of shell is the inclined plane that has certain inclination angle with horizontal plane, and backboard place inner surface and the base inner surface of shell are 90 degree, and inclination angle is the intersection place at backboard and base.Arrange like this and can realize the go-cart of " L " type in the time not promoting, stable being parked in bar shaped space.

Fig. 2 is the sectional view in single bar shaped space in the utility model embodiment;

Detailed description of the invention

As shown in Figure 1: a kind of chalk holder, comprise shell 1, the solid space that shell 1 surrounds is divided into polylith side by side by dividing plate 6, and width is less than the bar shaped space of 1.5 times of chalk diameters, and dividing plate 6 is to separate solid space by slot.Chalk 5 in bar shaped space can only be single placement.As shown in Figure 2: base 10 inner surfaces of shell 1 are the inclined planes that has certain inclination angle with horizontal plane, backboard 11 place's inner surfaces and base 10 inner surfaces of shell 1 are 90 degree, inclination angle is the intersection place with base 10 at backboard 11, inclination angle is 15～30 degree, this embodiment medium dip angle is 15 degree, 30 degree are maximums, and the resistance that exceedes 30 degree promotions becomes large.Bar shaped has " L " type go-cart 2 in space, have the chalk 5 of single placement in " L " type go-cart 2.The go-cart 2 of " L " type is slided in bar shaped space by pulley 4.When the go-cart 2 of " L " type is not in the time promoting, because base inner surface is inclined plane, make " L " type go-cart 2 stablize and be parked in bar shaped space.When determine need to this color chalk, can promote " L " type go-cart 2, chalk can be stretched out to shell, take conveniently, after taking, " L " type go-cart 2 can lean on again self gravitation to return on inclined plane.

In addition in Fig. 1 and Fig. 2, in outer casing base, also have dust suction cloth 7, the dust descending slowly and lightly for adsorbing bar shaped space chalk, benefit is to reduce the resistance to sliding of go-cart pulley, except embodiment represents, can also be storage dirt space certainly." L " type go-cart 2 has shifting block 3, and described shifting block 3 stretches out shell 1, and the benefit arranging is like this that user's promotion is convenient in go-cart.

More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
