Description
Technical field
The utility model relates to a kind of educational aid, especially a kind of politics and laws Lectern for teaching.
Background technology
Often need in politics and laws teaching process to use small blackboard or showing stand, for showing the content of courses, generally all needing support to support separately small blackboard or showing stand, thus causing at school, these equipment is needed all to be transported in classroom, waste time and energy, and in the process of giving lectures, dais is absolutely necessary, but existing dais, all there is function singleness, height is unadjustable, simultaneously guardrail non-removable shortcoming again.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of politics and laws Lectern for teaching, can regulate the height at dais as required, can be used for fixing other educational aids such as small blackboard or showing stand, and guardrail is detachable simultaneously.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of politics and laws Lectern for teaching, comprise base, rectangularly on base be disposed with four hydraulic lifting arms, the side of base is connected with all right one way or the other stool be accommodated in described base by rotating shaft, the top of hydraulic lifting arm is connected with dais by the first ring flange, dais surrounding is hinged with guardrail, the junction at guardrail and dais is provided with lock device, dais is fixed with fixed bar by the second ring flange, the end of fixed bar is provided with gear-box, gear-box is provided with handle, the upper surface of fixed bar is provided with several negative pressure suckers, fixed bar side is provided with several through holes, restraining is movably set with in through hole, fixed bar and horizontal plane are provided with the positive pitch of 2 ° ~ 4 °, described guardrail slides and is provided with sleeve pipe, sleeve pipe is provided with universal joint, universal joint is provided with illuminating lamp.
As preferably, the surface at described dais is provided with drawer.
The beneficial effect adopting technique scheme to bring is: base, dais and fixed bar, by Flange joint, are connected firmly, simultaneously convenient disassembly, in transportation, the dismounting of this device can be decomposed transport, convenient practicality.Guardrail can fold, and is fixed during use by lock device.Hydraulic lifting arm can adjust the height at dais.By turning handle driving gearbox, fixed bar can be made to move forward and backward, thus drive the small blackboard or showing stand that are fixed on fixed bar.Negative pressure sucker on fixed bar can be adsorbed in and be fixed on bottom small blackboard on fixed bar or showing stand, improves firmness.Restraining can be used to make fastness stronger simultaneously.Fixed bar and horizontal plane are provided with the positive pitch of 2 ° ~ 4 °, can avoid being fixed in moving process the problem that outwards toppling over appears in small blackboard on fixed bar or showing stand.Inclination angle is unsuitable excessive simultaneously, avoids being fixed on the small blackboard on fixed bar or generation slip between showing stand and fixed bar, and illuminating lamp can move and translation-angle as required, and the drawer that the surface at dais is arranged can place other educational aids.
