Novel blackboard

Abstract

The invention discloses a novel blackboard. The novel blackboard comprises a bearing board, wherein four symmetric universal wheels are arranged at the bottom part of the bearing board; four verticalthrough grooves are formed in the bearing board; a clamping block is arranged in each through groove; hollow supporting rods are obliquely arranged on the upper surface of the bearing board; a plurality of clamping grooves are formed in the supporting rods, and the clamping grooves are uniformly distributed along the inclination of the supporting rods from top to bottom; a sliding rod is arrangedin each supporting rod; and a fixing block is arranged at the lower part of each sliding rod. The novel blackboard is reasonable in design; the universal wheels are arranged at the bottom part of thebearing board; a handle is arranged, so that a user can easily slide the novel blackboard; the novel blackboard can be fixed through the clamping blocks; the sliding rods can be clamped into the clamping grooves, so that the user can conveniently adjust the height of the blackboard, and people with different height can use; in addition, an LED lamp is arranged and is capable of lighting in a darkplace, and thus people can conveniently see contents written on the blackboard.

Description

technical field [0001] The invention relates to a blackboard, in particular to a novel blackboard. Background technique [0002] The blackboard does not specifically refer to the black board surface.

Blackboards are generally made of wood or frosted glass, and can be written on with specific writing materials such as chalk. [0003] However, the current blackboards are not portable, and are generally used in classrooms. However, some lecturers will give lectures in other places after class, and the temporary blackboards are not only troublesome to assemble, but also difficult to carry. Contents of the invention [0004] The object of the present invention is to provide a novel blackboard that solves the above problems. [0005] In order to achieve the above object, the technical solution adopted by the present invention is as follo...
