Abstract

The utility model discloses a lifting platform which comprises rectangular pedals. The pedals are horizontally arranged below a blackboard; the side edges of the pedals are parallel to the bottom edge of the blackboard; the four corners of the bottom surface of the pedal are respectively provided with a corresponding guide mechanism; and a lifting mechanism is arranged in the middle of the bottom surface of the pedal. The lifting platform adopts a motor and a speed reducer which are matched for power driving; and under the action of the guide mechanisms at four corners of the bottom surface of the pedal, the lifting mechanism lifts steadily with low noise and easy control. The lifting platform relatively increases the standing height of a teacher who is short, the surface of the middle-upper part of the blackboard is used for writing, the vision of students is wide, and the teaching effect is good; and simultaneously, the surface of blackboard is fully utilized, thus being capable of reducing the number of times for cleaning the blackboard, leading to coherent teaching and attracting attention of students.

Description

A kind of lifting dais

Technical field

The utility model relates to a kind of dais that can lifting.

Background technology

The dais is arranged on the below of blackboard in the classroom, and blackboard mostly is rectangle, for the ease of back row's student viewing, during teacher's writing on the blackboard, needs to write toward the middle and upper part of blackboard as far as possible.The effect at dais is exactly the relative altitude that improves the teacher, makes teacher as far as possible effectively utilize the plate face of blackboard middle and upper part to write by the dais.Existing dais height generally immobilizes, because user's height differs, for teacher of short and small stature,, can not effectively utilize the middle and upper part of blackboard even by the raising effect at dais, only can utilize the middle and lower part of blackboard, like this, not only be unfavorable for student viewing, and owing to utilize less to the blackboard usefull space, a class often needs repeatedly to wipe, the teaching time that waste is valuable.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective of above-mentioned prior art and a kind of lifting dais easy to use is provided.

The alleged problem of the utility model is solved by following technical scheme:

A kind of lifting dais comprises that rectangle pedal, described pedal are placed horizontally at the blackboard below, and the pedal side is parallel with the blackboard base, and four jiaos of places, described pedal bottom surface are provided with corresponding guiding mechanism respectively, are provided with elevating mechanism in the middle of pedal.

Above-mentioned lifting dais, described elevating mechanism comprise motor and the reductor that is in transmission connection with it, and the output shaft on described reductor top is connected with leading screw by shaft coupling, and the screw of leading screw below being fixed on pedal cooperates.

Above-mentioned lifting dais, described guiding mechanism are lead and the guide holder that cooperatively interacts, and lead one end is fixed on below the pedal, and the other end and guide holder are slidingly matched.

Above-mentioned lifting dais, described tread width and blackboard width adequate.

Above-mentioned lifting dais, described pedal hoisting depth is 20-50cm.

The utility model adopts motor and reducer to cooperate as power drive, cooperates the guiding mechanism of four jiaos of pedal bottom surfaces, and system's lifting is steady, noise is little, easy to use.For teacher of short and small stature castering action is preferably arranged, make it to make full use of the most of plate face of blackboard, reduce the number of times that erases the board, help student viewing, it is effective to give lessons.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

The label of each parts is expressed as follows among the figure: 1. pedal; 2. motor; 3. reductor; 4. shaft coupling; 5. leading screw; 6. screw; 7. lead; 8. guide holder; 9. blackboard; 10. lectern.

The specific embodiment

Referring to Fig. 1, the utility model comprises that rectangle pedal 1, described pedal are positioned on the ground in wall the place ahead, blackboard 9 place, the guiding mechanism that lead 7 and guide holder 8 are formed is set around the pedal bottom surface, pedal intermediate supports elevating mechanism, described elevating mechanism comprises motor 2, reductor 3, described motor is connected with the reductor input, and the output shaft on reductor top is connected with leading screw 5 by shaft coupling 4, and the screw 6 of leading screw below being fixed on pedal cooperates.Described tread width and blackboard width adequate.Described pedal hoisting depth is 20-50cm.

Referring to shown in Figure 2, in the practical application, in wall the place ahead, blackboard place common dais is set, the front portion, dais is a lectern, the rear portion, dais is the lifting dais, when teachers' instruction is write writing on the blackboard, can realize promoting at any time user's relative altitude by the dual booster action in common dais and height-adjustable lifting dais, can be convenient to write writing on the blackboard in the most of plate face of blackboard position, to blackboard utilization rate height, the user writes laborsaving, and speed is fast.

The utility model is driving with the motor, and the shaft reductor is connected with leading screw in the drive, and leading screw is provided with screw, and screw and elevating stage are fixed, and cooperates the sliding sleeve guiding, and lifting is steady, noise is little, high safety.
