Description

Teaching education board

Technical Field

The utility model relates to a teaching equipment technical field specifically indicates a teaching education board.

Background

Teaching boards, as the name implies, are board elements used for writing teaching.

The existing teaching board is basically a board fixed at one position or a blackboard embedded and fixed into a wall, the board or the blackboard has limited use area, the writing area can not be changed according to the writing amount of teaching contents, the application range is smaller, and the existing board or the blackboard is less in mobility.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve foretell various problems, provide a simple structure, simple operation, portable fixed, can change the teaching education board of writing the area.

In order to solve the technical problem, the utility model provides a technical scheme does: a teaching education plate comprises a base, wherein a plurality of self-locking universal wheels are uniformly and fixedly arranged below the base through bolts, a support column is welded on the base, a plate is fixedly arranged on the support column through bolts, a plate expanding structure is arranged between the upper surface and the lower surface of the plate and comprises a U-shaped plate welded at the upper side edge and the lower side edge of the front surface of the plate, openings of the U-shaped plate at the upper side edge and the lower side edge are oppositely arranged, a plate II is slidably arranged between the U-shaped plates and close to the two side edges, racks are welded at the upper surface and the lower surface of the plate II extending into the U-shaped plate, two motor shells are fixedly arranged at the middle part and the lower middle part of the upper surface of the plate through bolts, motors are fixedly arranged in the motor shells through bolts, and gears matched and meshed with the racks are sleeved on the output ends of the motors, the U-shaped plate is provided with a through hole for the gear to extend into, and the motor and the lower motor are symmetrically arranged on the plate.

As an improvement, the opposite inner side surfaces of the U-shaped plates are provided with sliding grooves, and the racks slide in the sliding grooves.

As an improvement, hanging rods are welded at the positions, close to the outer side edges, of the front faces of the second plate pieces.

As an improvement, a reinforcing plate is welded between the upper surface of the base and the side surface of the supporting column.

Compared with the prior art, the utility model the advantage lie in: when the utility model is used, the motor can be controlled to rotate by the arrangement of the plate extension structure according to the writing content, so that the plate II is driven to slide between the U-shaped plates, the writing area is controlled, the application range is wide, and the placing space is saved when the writing device is not used; the arrangement of the self-locking universal wheel can be used for moving and fixing the utility model, which is convenient and reliable; the arrangement of the sliding groove can enable the second plate to move more stably and reliably; the setting of peg can be used to hang teaching aids such as set square, and is comparatively convenient.
