The utility model is characterized in that both sides of the platform base are provided with lower slideways; both sides of the platform surface are also provided with upper slideways; both ends of a connecting rod are respectively provided with a pair of supporting bars hinged in an X shape; both ends of the supporting bars are provided with pulleys; the pulleys are arranged in the lower slideways and the upper slideways; four hydraulic cylinders are arranged in the lower slideways; and each hydraulic cylinder is connected with one end of one supporting bar, which is near the lower slideways. The utility model has the characteristics that the structure is novel, the operation is simple and convenient, the safety and reliability are high and the like, and is beneficial to the health of teachers, and therefore, the lifting platform belongs to a novel lifting platform integrating economy and practicability.

Description

The lifting dais

Technical field

Lifting described in the utility model dais relates to the liftable dais of using in a kind of teaching.

Background technology

At present the dais of using in the teaching mostly is rectangular fixedly dais, and the teacher often will teach at the enterprising andante book of blackboard at school the time, and the teacher will write on blackboard in a large number like this.Teacher is often lifting arm like this and is writing, be easy to the shoulder disease of scapulohumeral periarthritis, in addition, because the writing on the blackboard of writing is higher than head, a large amount of chalk bits can be sucked lung by teacher, and the healthy of teacher impacted.At existing problem in the above-mentioned prior art, a kind of novel lifting dais of research and design, existing problem is very necessary in the prior art thereby overcome.

Summary of the invention

In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel lifting dais of research and design.In order to what exist in the solution prior art; 1, teacher's carry arm is write writing on the blackboard, the injury that teacher's shoulder is caused; 2, writing on the blackboard is higher than head and writes, and a large amount of chalk bits can be sucked lung by teacher, and the healthy of teacher impacted.

Technical solution of the present utility model is achieved in that

Lifting described in the utility model dais is by the dais base, say that table top is formed; It is characterized in that glide path being housed in the both sides of dais base; The both sides of saying table top are equipped with sliding way equally; Respectively there is the hinged support bar of a pair of one-tenth " X " type at the two ends of connecting rod, and pulley is equipped with at the two ends of support bar, and pulley places in glide path and the sliding way; 4 hydraulic cylinders are housed in glide path, and each hydraulic cylinder all is connected with the end of a support bar near glide path.

The hydraulic cylinder that primer fluid pressure device during use, hydraulic means drive in the slideway starts, and the piston rod of hydraulic cylinder is released, and support bar is boosted, and drives to say that table top raises.Make teacher rise to certain altitude and write, so both reduced the raising height of arm, make head not be higher than the height of writing on the blackboard again.Health to teacher has played protective effect.

The utility model has the advantages that conspicuously, mainly show:

1, owing to used the utility model, make teacher when writing writing on the blackboard, what arm need not be too is too high, has reduced the possibility that teacher suffers from shoulder disease such as scapulohumeral periarthritis;

2, owing to used the utility model, make teacher when writing writing on the blackboard, writing on the blackboard is lower than teacher's head, can reduce to suck the chalk bits, has reduced the possibility that teacher changes PUD D.

The utlity model has novel structure, easy and simple to handle, safe and reliable, the advantage such as healthy that helps teacher, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.

Description of drawings

The utility model has 2 width of cloth accompanying drawings, wherein:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is a side view of the present utility model.

In the drawings: 1, dais base 2, with table top 3, slide into 4 down, pulley 5, support bar 6, hydraulic cylinder 7, sliding way 8, connecting rod.

The specific embodiment

Specific embodiment of the utility model as shown in drawings, by dais base 1, say that table top 2 is formed; It is characterized in that glide path 3 being housed in the both sides of dais base 1; The both sides of saying table top 2 are equipped with sliding way 7 equally; Respectively there is the hinged support bar 5 of a pair of one-tenth " X " type at the two ends of connecting rod 8, and pulley 4 is equipped with at the two ends of support bar 5, and pulley 4 places in glide path 3 and the sliding way 7; 4 hydraulic cylinders 6 are housed in glide path 3, and each hydraulic cylinder 6 all is connected with the end of a support bar 5 near glide path.

The above; it only is the preferable specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; all are familiar with those skilled in the art in the disclosed technical scope of the utility model, are equal to replace or change according to the technical solution of the utility model and design of the present utility model thereof all should be encompassed within the protection domain of the present utility model.
