The invention relates to a combined white board capable of being quickly spliced and a splicing method. The combined white board is characterized in that the back surface of a first board body is provided with a first guide hanging nail; a second guide hanging nail is arranged on the back of the second plate body; a first outer frame comprises a first baffle, and a first guide hanging nail hole is formed in the first baffle; a second outer frame comprises a second baffle, and a second guide hanging nail hole is formed in the second baffle, wherein one end, used for clamping a first guide hanging nail, of the first guide hanging nail hole is opposite to one end, used for clamping a second guide hanging nail, of the second guide hanging nail hole, and a tensioning mechanism is arranged between the first outer frame and the second outer frame. When the first outer frame and the second outer frame are fixed in a butt joint manner, the first guide hanging nail and the first guide hanging nail hole are clamped, and meanwhile the second guide hanging nail and the second guide hanging nail hole are clamped. The advantages of the white board are that the first plate body, the second plate body, the first outer frame and the second outer frame do not need to be connected through screws, and the firm and stable splicing effect can be achieved.
Description
technical field [0001] The invention relates to the technical field of teaching auxiliary equipment, in particular to a fast-assembled combined whiteboard and an assembling method. Background technique [0002] The electronic whiteboard is a high-tech product that integrates various high-tech means such as cutting-edge electronic technology and software technology. The working principle of the electronic whiteboard can be divided into two types: the principle of pressure sensitivity and the principle of laser tracking. The sensing range generally covers the entire whiteboard. In today's digital society, electronic whiteboards are used in more and more fields, such as scientific research, teaching training, academic exchanges, etc. Electronic whiteboards have become a basic teaching tool. In order to meet the needs of teaching, especially the large-size and large-screen requirements of large lecture halls, the screens of existing electronic whiteboards are generally large, a...
