Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides one and has traditional lectern function, and can be deformed into university's lectern of Simple blackboard.
The purpose of this utility model realizes by following technical proposal: a kind of university lectern, comprise platen, base plate, front side board, left plate and right plate, it is characterized in that: described left plate and right plate arranged in parallel, described platen, base plate and front side board are all vertical with right plate with left plate to be connected, and platen and base plate are parallel to each other and are vertically connected on side, the front side board back side, also comprise and be vertically hinged on blackboard between left plate and right plate by bearing pin, described blackboard has the plate face for writing, described plate face and side, front side board front offset, now described blackboard along articulated section straight down, also comprise the bracing frame be hinged on left plate and/or right plate, the blackboard back side contrary with plate face on described blackboard is provided with some draw-in grooves, described blackboard and bracing frame all can rotate along respective articulated section, and bracing frame can be stuck in draw-in groove the blackboard described in also supporting, now described plate face and front side board are just facing to the same side.
During use, teacher can utilize platen to use as general lectern, when needs are demonstrated on blackboard, along articulated section Revolving blackboard and bracing frame, to be coordinated with draw-in groove by bracing frame and support blackboard, now plate face and front side board are just facing to the same side, are the direction in the face of student, and therefore this lectern can become Simple blackboard use fast.
In above-mentioned a kind of university lectern, described bracing frame is in " Contraband " font, comprise be parallel to each other left side bar and right-hand rod, described left side bar and right-hand rod are hinged on left plate respectively with on right plate and rotation is identical, described left side bar and right-hand rod are connected with support bar away from one end of articulated section is vertical, described draw-in groove is bar shaped and parallel with described support bar, and described support bar to be stuck in described draw-in groove and to make bracing frame support blackboard, described bracing frame also can entirety be resisted against on platen.
Therefore can be adjusted the angle of blackboard inclination by they sup-port in different draw-in groove, use more comfortable.
In above-mentioned a kind of university lectern, described plate face is the arc of indent, and blackboard is greater than the thickness in the middle of blackboard near left plate with near the thickness of right plate.
Therefore the comparatively suitable small class in the plate face of arc, teachers and students' spacing of being convenient to further carries out interaction.
In above-mentioned a kind of university lectern, described bracing frame entirety is resisted against on platen, and when simultaneously plate face and front side board offset away from the side of platen, described bracing frame and the blackboard upright projection on right plate is positioned at the upright projection of left plate at right plate.
When therefore using as traditional lectern, blackboard and bracing frame can not hamper use.
Compared with prior art, the utility model tool has the following advantages:
During use, teacher can utilize platen to use as general lectern, when needs are demonstrated on blackboard, along articulated section Revolving blackboard and bracing frame, to be coordinated with draw-in groove by bracing frame and support blackboard, now plate face and front side board are just facing to the same side, are the direction in the face of student, and therefore this lectern can become Simple blackboard use fast.
