Abstract
The utility model belongs to a demonstrating and experimental table for experimental teaching, which comprises a table body, a table top with a lifting platform, a reflecting mirror, a tube-shaped support leg with a caster, a lifting upright post which is sheathed in the tube of the support leg, and an article carrying partition board. Because the table top of the utility model has a lifting function, and the reflecting mirror is arranged above the table top for the people to observe the experimental phenomena, the utility model is suitable for various demonstrating experimental teaching. The utility model has the advantages that the visibility for the students to observe the experimental phenomena is high; the visual range is broad; the height can be conveniently adjusted; the movement is flexible; the applicability is strong; the effect of the experimental teaching can be effectively enhanced, etc.
Description
The utility model belongs to the laboratory table that is used for lecture experiment in school's experimental teaching, particularly a kind of band lifting platform, speculum and movable comprehensive laboratory table.
At present, in the experimental teaching of all kinds of schools, generally all on dais or fixed laboratory table, carry out various lecture experiments.And the experimental teaching of school is many owing to subject, and the experiment kind is numerous and diverse, and the mode of all kinds of experiments and requirement are not quite similar again.And conventional dais and fixedly laboratory table owing to highly non-adjustable, move again inconvenient, particularly for some such as the experimental phenomena that takes place in the plane etc., the student has only in turn last dais to watch or the teacher is holding touring demonstrations in the classroom such as instrument, thereby has had a strong impact on the effect of experimental teaching.Therefore, on this class dais or laboratory table, carry out the bad adaptability of demonstration of experiment teaching existence to dissimilar experiments, the visibility of observation experiment phenomenon is low, and visual range is narrow and also can block the disadvantages such as sight line that the student watches teacher's writing on the blackboard on the plate when placing bigger experimental provision on the dais.
The purpose of this utility model is to design the lecture experiment table that each the section's experimental teaching of a kind of suitable school is used, to reach all kinds of lecture experiments can be carried out at suitable height, improve visibility and visual range that experimental phenomena is observed, the effect and the laboratory table itself that improve experimental teaching are easy to adjust, move flexibly purpose such as adaptability is strong.
Solution of the present utility model is a Lifting platform to be set on the table in order to place the experiment utensil and the operation that experimentizes, and can regulate its height according to the size of experimental provision and the kind of experiment simultaneously; Be provided with on the table again 2～4 lifting vertical rods in order to stationary mirror etc. so that with the rear structure correlation of the phenomenon that takes place on the plane and experimental provision or experiment itself or phenomenon by minute surface to student's reflection with show; For laboratory table is moved, rotate flexiblely, under support foot, also be provided with universal wheel.Therefore, the utility model comprises a body, desktop and support foot; Key is that desktop is the combining structure desktop that has Lifting platform, also is provided with liftable column on the desktop and is fixed in speculum on the column; Support foot is the tubular support pin, and its lower end is provided with universal wheel; Lifting platform is connected and the lifting location with a table body by the slide bar of the movable locking member of screw rod or band, and lifting column is placed in versatilely in the pore of tubular support pin and by locking member and its activity and fixes.When the Lifting platform of above-mentioned laboratory table adopts screw rod to be connected with a table body and lifting when locating, then can adopt the handwheel of being with bevel gear set and be located at bevel gear and screw rod between nut sleeve as its elevating mechanism.For the ease of depositing experiment article and assistive device, under desktop, also be provided with 1～2 layer of loading dividing plate.
The utility model is because desktop adopts the combined type desktop of band Lifting platform, therefore can experimental type and the design feature of experimental provision etc. regulate its height; The side is provided with mirror surface on the table, again can with such as take place in the plane experimental phenomena and the rear structure of experimental provision or experiment itself, the whole process of correlation or experimental phenomena clearly reflects to the student; Owing to be provided with universal wheel on support foot, make whole laboratory table conveniently moving flexible in addition, desktop has elevating function in addition, both laboratory table can have been moved when teacher's writing on the blackboard, also can reduce the height of experimental provision in order to avoid the overslaugh student sees the sight line of writing on the blackboard.Therefore, the utlity model has and can be fit to all kinds of demonstration of experiment teaching, and the visibility height observed of experimental phenomena, visual range is wide, can improve the effect of experimental teaching effectively, and laboratory table is easy to adjust.Move characteristics such as flexible, that adaptability is strong.
