Abstract
The utility model discloses a chalk box. The chalk box comprises a chalk box body, wherein a cover plate is arranged at the upper part of the chalk box body; a bottom plate is arranged at the lower part of the chalk box body; a position between the bottom plate and the cover plate in the chalk box body is divided into a chalk cavity for placing chalks, a battery cavity for containing a battery and a control cavity for mounting a control device; the chalk cavity is positioned at the upper part of the the battery cavity, and is separated by a separation plate; the control cavity is located at one side of the battery cavity and is also separated by a separation plate; the chalk cavity and the control cavity are communicated by a communication opening; the control cavity is internally provided with a slide rail; the slide rail is fixedly connected with the bottom plate; the slide rail is slidingly connected with a rack; one end, which is close to the communication opening, on the rack is fixedly connected with a slide block; the slide block is provided with a V-shaped groove; an opening of the V-shaped groove corresponds to communication opening in position; the gear drives the rack to move and the rack drives the slide block to move, so as to push the chalks out from the inner part of the chalk box body and further facilitate fetching of the chalks.
Description
Technical field
The utility model relates to teaching aid field, relates to specifically a kind of chalk holder.
Background technology
Existing chalk holder mostly is carton, and box cover fastens, and all will open lid at every turn and in box, chalk, take out one with hand while using chalk, take very inconvenient, wearing and tearing, the phenomenon that fractures of chalk easily occur in use procedure, and carton easily breaks, residue chalk is not good at causing waste because depositing.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, and a kind of chalk chalk holder easily of taking is provided.
For addressing the above problem, the utility model by the following technical solutions:
A kind of chalk holder, comprise chalk holder body, the top of described chalk holder body is provided with cover plate, the bottom of chalk holder body is provided with base plate, the position of described chalk holder body interior between base plate and cover plate is divided into for holding the chalk chamber of chalk, for holding the battery cavities of battery and for the control chamber of control device is installed, described chalk chamber is positioned at the top of battery cavities and separates by dividing plate, the side that described control chamber is positioned at battery cavities also separates by dividing plate, between described chalk chamber and control chamber, by connected entrance, be communicated with, in described control chamber, establish slide rail, described slide rail is fixedly connected with base plate, on described slide rail, slidably connect tooth bar, one end near connected entrance on described tooth bar is fixedly connected with slide block, on described slide block, offer V-type groove, the opening of described V-type groove is corresponding with the position of connected entrance, one end away from slide block on described tooth bar is connected with gear, in described control chamber, be fixedly connected with motor, described motor is connected with gear drive, described chalk holder body is provided with inductor, in described control chamber, be provided with controller, described controller is electrically connected to inductor, described controller is electrically connected to motor.
The utility model adopts technique scheme, by human body touch inductor, inductor passes to controller by signal, controller is controlled electric motor starting, motor driven gear motion, the motion of gear driven tooth bar, rack drives slide block movement, and then chalk is released to the chalk of conveniently taking from chalk holder body interior.
Below in conjunction with accompanying drawing the technical solution of the utility model, be described further.
