Abstract
The invention provides a multifunctional chalk support and belongs to the field of teaching tools. The chalk support solves the problem that existing chalk supports are not suitable for being placed on various occasions. The multifunctional chalk support comprises a body, the body comprises an upper supporting plate and a lower supporting plate which are arranged in parallel, and the upper supporting plate and the lower supporting plate are provided with supporting holes and supporting grooves respectively. The supporting grooves are formed by stamping the lower supporting plate. Protrusions are formed at the bottom of the lower supporting plate. The supporting holes and the supporting grooves are coaxially formed. The supporting holes and the supporting grooves are sequentially and correspondingly arranged in the upper supporting plate and the lower supporting plate respectively and are distributed in a matrix. One side, in the length direction, of the upper supporting plate and one side, in the length direction, of the lower supporting plate are connected through a connection plate. The other side, in the length direction, of the upper supporting plate and the other side, in the length direction, of the lower supporting plate are bent to form an upper clamping strip and a lower clamping strip respectively. The side, far away from the connection plate, of the upper clamping strip and the side, far away from the connection plate, of the lower clamping strip are connected with magnetic strips respectively, and the upper supporting plate, the lower supporting plate and the connection plate are formed by bending rectangular steel plates. The chalk support can adapt to the requirement for chalk placement on different occasions.

Chalk is penetrated in supported hole, and make chalk end be placed in support slot, chalk can be fixed, upper clamp bar and the cooperation of lower clamp bar can be fixed with the ledge for chalk on blackboard front end snap-fit engagement bottom blackboard afterwards, also can be adsorbed fixing by magnetic stripe and blackboard, or directly utilize raised support on the table, therefore this chalk bearing can adapt to the needs that different occasion places chalk.
In above-mentioned a kind of multifunctional chalk bearing, described upper backup pad bottom surface and supported hole correspondence position are provided with the annular guide ring arranged towards support slot.
Guide ring is set and conveniently places chalk.
In above-mentioned a kind of multifunctional chalk bearing, described lower supporting plate is bent to form two bar shaped legs be parallel to each other respectively near the side of connecting plate with near the side of lower clamp bar respectively bottom lower supporting plate.
Therefore convenient placement on the table.
In above-mentioned a kind of multifunctional chalk bearing, described support slot is inversed taper platform shape structure, and support slot notch is greater than support slot bottom land.
Therefore the chalk of different size can be adapted to.
In above-mentioned a kind of multifunctional chalk bearing, described support slot bottom land is provided with beam.
The moment putting into chalk is avoided to produce noise.
In above-mentioned a kind of multifunctional chalk bearing, described upper backup pad and lower supporting plate are respectively equipped with four supported holes and four support slots.
Compared with prior art, tool of the present invention has the following advantages:
Chalk is penetrated in supported hole, and make chalk end be placed in support slot, chalk can be fixed, upper clamp bar and the cooperation of lower clamp bar can be fixed with the ledge for chalk on blackboard front end snap-fit engagement bottom blackboard afterwards, also can be adsorbed fixing by magnetic stripe and blackboard, or directly utilize raised support on the table, therefore this chalk bearing can adapt to the needs that different occasion places chalk.
