Description

An easy-to-use chalk box

technical field

The utility model relates to an easy-to-take chalk box, which belongs to the technical field of appearance structure design.

Background technique

As one of the main teaching tools, chalk still plays an important role in the multimedia age. However, in the classroom of the school, many chalk stubs can be seen everywhere. Users often place unused chalk on the lower edge of the desk or blackboard, which will cause the unused chalk to roll down to the corner or the ground, causing a lot of inconvenience for the user to take the chalk, and for convenience, the user Often can get new chalk again, just caused the waste of chalk. Therefore, designing a simple device that is convenient for taking chalk can not only bring convenience for users to teach, but also save teaching tools in daily teaching. Regarding the design of the chalk box, there are already many related patents. Among them, in terms of the structural design of taking chalk, it is mainly a pop-up type, such as a patent named "A Rebound Chalk Box" (Patent No. CN201620565228.X) , is to eject the chalks one by one. It is simple and quick to take, but considering the different sizes of the two ends of the chalk, when the chalk is ejected, the chalk is easy to distort, and the dust will fall when it is scratched to the ejection port. . Another patent named "A Separated Chalk Box" (Patent No. CN201620815568.3) uses the principle of leverage to set the chalk box as a pop-up type. It is very convenient to take chalk, but the overall volume is slightly larger, and the chalk box is placed On the desk, the user will often turn around to take the chalk when doing blackboard writing, and the flexibility of use is not high.

Utility model content

Purpose of the invention: Aiming at the problems existing in the prior art, the purpose of this utility model is to provide a chalk box that is easy to use, has high flexibility in use, and can effectively reduce the loss and waste of chalk.

Technical solution: In order to achieve the above object, the utility model adopts the following technical solution:

An easy-to-use chalk box, comprising a lower main body, an upper tray and a side storage box; the lower main body is a hollow cuboid box without a cover, and a chalk ejection mechanism is provided at the lower part; the ejection mechanism includes a main shaft, a second A partition, a second partition, a push plate switch and a spring device; the two ends of the main shaft are fixed on the box body inside the lower body, one end of the first partition is fixed on the main shaft, and the other end is connected to the press plate The switch is connected, and the spring device is connected between the bottom surface of the first partition and the bottom of the box; the second partition is fixed obliquely above the first partition, and there is less than one gap between the first partition and the second partition. The gap is the width of a piece of chalk; the upper tray is placed on the upper end of the lower body; the side storage box is adsorbed to the side of the lower body by a magnetic suction cup.

Preferably, the back and at least one side of the lower body are provided with a magnetic suction cup.

Preferably, at least one side of the side storage box is provided with a magnetic suction cup.

Preferably, the upper tray is a hollow cuboid structure without a cover, and the bottom end is embedded in the upper end of the lower body.

Preferably, the side storage box is a hollow cuboid structure without a cover, the height of the cuboid is consistent with the height after the upper tray and the lower body are connected, and the side width is consistent with the side width of the lower body.

Beneficial effects: compared with the prior art, the utility model provides an easy-to-take chalk box, which can be placed on the lecture table, or can be arbitrarily adsorbed to the blackboard. When the user is writing on the blackboard, he can stick the chalk box on the blackboard where he can easily reach it. After using up the chalk, he can put the chalk into the tray of the chalk box so that he can use it next time and replace it with a new one. At the same time, the new chalk can be automatically rolled down to the outlet by pressing the chalk box button switch, which reduces the loss and waste of chalk and makes it easier to take the chalk. The side storage box can store sundries such as blackboard erasers and pens, and can also be removed and adsorbed to the blackboard separately, which enhances the flexibility of the device and realizes the multi-functional use of the chalk box.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.

As shown in Fig. 1, a kind of easy-to-take chalk box disclosed by the embodiment of the utility model is mainly composed of a lower body 1, an upper tray 2 and a side storage box 3. The upper tray 2 is covered on the main body 1, and the side storage box 3 and the main body 1 can be used after being assembled with a suction cup. The material of each part can be various materials such as plastics and wood, and the appearance of each part can be a cuboid box with different sizes. The specific structure is as follows:

(1) Lower body

As shown in Figures 2 and 4, the lower main body 1 is mainly composed of a main shaft 11, a first partition 12, a second partition 13, a push switch 14, and a spring device 15. Both sides and the back can be equipped with magnetic suckers. The board switch 14 can be formed by connecting two rectangular short boards at an angle of about 90 degrees. Fix both ends of the main shaft 11 on the back of the box body, fix one side of the first partition 12 on the rotatable main shaft 11, and the opposite side is connected to the push switch 14, and a spring is connected between this side and the bottom of the box The device 15 is obliquely fixed above the first dividing plate 12 with the second dividing plate 13, so that there is a gap slightly smaller than the width of a piece of chalk between the second dividing plate 13 and the first dividing plate 12.

(2) Upper tray

As shown in Figure 3, the upper tray 2 is the cover of the main structure, which is a hollow cuboid structure with no cover at the upper end, the bottom size is consistent with the top size of the main body, and the lower end of the bottom surface is set as a cuboid structure with a size slightly smaller than the size around the main body. so that it just fits into the upper end of the main body.

(3) Side storage box

As shown in Figure 5, the side storage box 3 is a hollow cuboid structure without a cover. It can be sucked with the suction cup 18 on the side of the main body.

During use, the upper cavity 16 of the first partition 12 in the structure of the main body 1 can place chalk horizontally, place some chalk and cover the upper tray 2 structure, when the user manually presses the push plate switch 14, the push plate is pressed downwards The effect of power drives the second dividing plate 13 to rotate downwards with the main shaft as the center. At this time, there will be a space for a piece of chalk to pass between the first dividing plate 12 and the second dividing plate 13, and the chalk will pass through it due to its own gravity. After the space, roll down to the baffle plate at the front end of the panel switch 14 along the second dividing plate 13 and stop, and the user can take out the chalk and use it. And, the unused chalk of the user can be placed in the upper tray 2, so that continue to use next time, can prevent that chalk is placed on the desk in disorder and cause loss and other consequences make it inconvenient to continue to use, also can prevent chalk from falling Waste caused by breaking on the ground. The side storage box 3 can place sundries such as fountain pens and blackboard erasers, and combining such teaching tools together can effectively keep the teaching environment clean and hygienic.

At the same time, the user can suck the suction cup 17 on the back of the main body to the blackboard, making it easier to take the chalk at any time when writing on the blackboard. The side storage box 3 can be sucked to the side of the main structure by the suction cup, and can also be removed and used alone. When used alone, it can be placed on the desk or can be adsorbed to the blackboard by the suction cup on the side.
