A new type of multifunctional combination push-pull teaching board

Abstract

The invention discloses a novel multifunctional combined push-pull teaching board. The novel multifunctional combined push-pull teaching board structurally comprises a left rotation disc, a board frame, a left panel, a handle, a right panel and a right rotation disc. The left rotation disc is mainly used for carrying out a uniform operation of pushing and pulling between the left panel and the right panel, so that the combination of the panels is facilitated; the right rotation disc is mainly used for operating together with a storage device in the board frame; the storage device is capable ofstoring chalks, blackboard erasers and some teaching aids; through the storage device and a lifting and jacking mechanism, a winding and coiling device, a worm driving mechanism and a coiling drivingdevice which are matched with the right rotation disc, the operation of movably pushing and pulling the storage device is achieved; when the teaching aids are not used, the storage device can be rotated into the bottom end of the board frame; the storage device can be pushed out by just positively rotating the right rotation disc under the usage condition; the multifunctionality of the teaching board is achieved; the teaching board is convenient to operate and use; the practicability of the teaching board is improved.

Description

technical field [0001] The invention is a novel multifunctional combined push-pull teaching board, which belongs to the field of teaching equipment. Background technique [0002] The teaching board is the utensil used for writing demonstrations in the education industry. Usually, the teaching board is a board placed in the classroom or in the meeting room. The content is written with chalk or water-based pen, which plays the role of explaining the demonstration. The predecessor of the teaching board is a blackboard. , the traditional blackboard is to simply apply black paint on the surface of a hard object such as a flat wooden board or cement board, and write with chalk after the black paint dries. The cost of the blackboard is low, and its corrosion resistance is poor. After long-term use, the surface will become uneven , can only be obtained locally, and it is difficult to repair after damage. The surface of the blackboard is reflective and easy to fade, so the blackboar...

Problems solved by technology

[0003] In view of this, the embodiment of the present invention provides a new type of multi-functional combined push-pull teaching board to improve the existing teaching board which is only limited to teaching use, the function is too single, and it cannot be stored for some utensils other than teaching. , and the use between the two push-pull plates is too cumbersome, it is necessary to artificially push and pull the two sides to merge, it cannot be operated uniformly, and the practicability is poor.
