Description
[technical field]
The utility model relates to a kind of English teaching dais, more specifically, relates in a kind of English teaching the dais that can project four line lattice, belongs to English teaching field.
[background technology]
On blackboard, write English word in process of English teaching assists student memory word to be absolutely necessary teaching means, in order to allow the memory and eye impressions of strengthening student, teacher needs to realize drawing four line lattice on blackboard, then on four line lattice, write English word, the English word writing out is like this more carefully and neatly clear, and the eye impressions of student are stronger, be convenient to memory, but, blackboard is drawn four line lattice and not only loses time, and drawn four line compartments are apart from being difficult to ensure neat and consistent.
[utility model content]
The utility model is drawn four line lattice for solution and is not only lost time on blackboard, and drawn four line compartments are apart from being difficult to the problem ensureing neat and consistent, and then proposes the dais that can project four line lattice in a kind of English teaching.
For achieving the above object, the technical scheme that the utility model is taked is: the utility model comprises base plate, hoistable platform, lifting motor, four line lattice projecting lamps, support, rotating shaft, driven gear, driving gear, angular adjustment motor and four cant boards, base plate and four cant boards form the rectangular box of a upper end uncovered, lifting motor is arranged on the middle part of plate upper surface, hoistable platform is horizontally set in described casing, and the middle part of hoistable platform lower surface is connected with the push rod of lifting motor, support installing is on the upper surface of hoistable platform, four line lattice projecting lamps are rack-mount by rotating shaft, driven gear is sleeved in rotating shaft, driving gear is sleeved on the turning cylinder of angular adjustment motor, driven gear engages with driving gear.
Compared with prior art, the utility model has following beneficial effect: when 1, the utility model uses, lifting platform is shifted onto the top of casing by lifting motor, four line lattice project on blackboard by four line lattice projection lamps, teacher can write English word in the upper four line lattice projections of blackboard, by angular adjustment motor, can realize the conversion of four line lattice projecting lamp crevice projection angles, and then realize the change of the position that four line lattice project on blackboard, facilitate the use of teacher; 2, the light formula four line compartment of the utility model projection is apart from consistent, and can project at any time, without the need to setting-out, effectively raises efficiency of teaching; 3, the roller with brake pedal of base plate lower surface enables whole dais move to any position easily, and after stepping on brake pedal, dais can keep stable and is not moved and rocks; 4, cover plate can prevent dust from entering in casing, maintains cleaning in casing.
[accompanying drawing explanation]
Fig. 1 is overall structure schematic diagram of the present utility model;
The following drawings mark is marked by reference to the accompanying drawings on figure:
