Description

Large-breadth writing board

Technical Field

The utility model relates to a big breadth clipboard belongs to education and equips technical field.

Background

The electronic blackboard is a high-tech interactive teaching product, seamless switching between a handwriting blackboard and an intelligent electronic blackboard in the traditional teaching can be realized through touch control, and the traditional teaching blackboard is changed into a sensible interactive blackboard, so that the teaching is gradually intelligentized; compared with the traditional blackboard, the electronic blackboard has more convenient information processing and more vivid demonstration. The electronic blackboard generally is based on display screen and host computer, can produce more heat at the during operation, and the electronic blackboard among the prior art does not generally carry out the design in the aspect of the heat dissipation well, and long-time accumulation can influence the work and the life-span of electronic blackboard.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a large format clipboard, this large format clipboard had both practiced thrift the cost, had alleviateed weight, had good structural stability and intensity again, still can provide good installation and radiating environment for the device that generates heat rather than the electronic blackboard that cooperates the use, extension electronic blackboard's life.

In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a large format clipboard, includes the aluminium sheet layer, the layer of writing of coating on the surface of aluminium sheet layer, another of aluminium sheet layer is connected with an at least aluminium strip on the surface, aluminium strip and aluminium sheet layer adhesive bonding, aluminium strip back of the body aluminium sheet layer on the surface spaced apart have a plurality of to be used for installing the mounting hole of electron device.

The further improved scheme in the technical scheme is as follows:

1. in the scheme, the aluminum strips are connected with the aluminum plate layer in a bonding mode through the heat conducting glue layer.

2. In the above scheme, the number of the aluminum strips is 4.

3. In the scheme, the 4 aluminum strips are connected end to end and are arranged into a rectangle.

4. In the scheme, the thickness ratio of the aluminum strips to the aluminum plate layer is 1.

5. In the scheme, the thickness of the aluminum plate layer is 0.5 cm-1.5 cm.

6. In the above scheme, the intelligent blackboard comprises a touch display device and at least one large-format writing board.

7. In the above scheme, the touch display device includes a panel, a touch film, and a display screen.

8. In the scheme, the panel is a glass blackboard.

Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:

the utility model discloses big breadth clipboard, it includes the aluminium sheet layer, the layer is write to coating on the surface on the aluminium sheet layer, another on the aluminium sheet layer is connected with an at least aluminium strip on the surface, aluminium strip and aluminium sheet layer adhesive connection, aluminium strip back of the body aluminium sheet layer on the surface spaced apart have a plurality of to be used for installing the mounting hole of electron device, both practiced thrift the cost, alleviateed weight, have good structural stability and intensity again, still can provide good installation and radiating environment for the electron blackboard's that uses rather than the cooperation heating device, extension electron blackboard's life.
