[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of new infrared electronic whiteboard, and it is more firm that the electronic whiteboard body is combined with the infrared touch frame, and demolition, installation are more convenient.
The utility model is achieved in that
A kind of new infrared electronic whiteboard, comprise an electronic whiteboard body and infrared touch frame, described infrared touch frame comprises a upper side frame, one lower frame, one left frame and a left frame, described upper side frame, left frame, lower frame and left frame surround successively and form a rectangle infrared touch frame, and all link to each other by cornerite between two frames, wherein, described upper side frame, lower frame, the back side of left frame and left frame is equipped with at least two hardy holes, the major part of the hardy hole that arranges on described left frame and the left frame is in the infrared touch frame, the microcephaly is outside the infrared touch frame, four limits of described electronic whiteboard body are provided with the screw corresponding with infrared touch frame hardy hole, and each screw is inserted in corresponding hardy hole, the diameter of described screw and hardy hole microcephaly's in the same size.
Further, an end of the infrared circuit board chute of described upper side frame, lower frame, left frame and left frame is provided with a screw hole, and each infrared circuit board is all located in the infrared circuit board chute of Bolt to position by one of DRIVE SCREWS hole.
The utility model has the advantage of:
Be provided with at least two hardy holes on four frames of infrared touch frame, four limits of described electronic whiteboard body are provided with the screw corresponding with infrared touch frame hardy hole, and each screw is inserted in corresponding hardy hole, the infrared touch frame is connected with screw by hardy hole with the electronic whiteboard body, so that the combination of the two is more firm, difficult drop-off;
The diameter of described screw and hardy hole microcephaly's in the same size, screw are inserted in from the major part of hardy hole first, stick among the microcephaly again, can play position-limiting action to screw, again screw is slided toward the major part place of hardy hole during dismounting, take out at last and get final product, so demolition, installation very convenience all;
Each infrared circuit board is all located in the infrared circuit board chute by a screw in DRIVE SCREWS hole, can prevent that infrared circuit board from sliding, and guarantees result of use and the sensitivity of electronic whiteboard.
