Description
Technical field
The utility model relates to a kind of jack type liftable desk.
Background technology
Desk is the equipment of school's necessity.At present, most of desks do not possess elevating function.The desk that minority has an elevating function is to use to be cut pin device and realizes lifting.Having the liftable desk of cutting pin device is to fix with screw and nut on table leg, allows school do adjusting work.But most schools not too pay attention to this problem, often only once regulate when buying, and just seldom move it later on.Correct way should be a height of per term adjusting desk according to different children's the situation of growing.And the liftable terseness that makes things convenient for of desk is the big problem that present desk faces.
The utility model content
The purpose of this utility model provides a kind of jack type liftable desk that uses more convenient and quicker, has realized the function of desk lifting quickly and easily.
To achieve these goals, the utility model adopts following technical scheme:
A kind of jack type liftable desk that is exclusively used in the students in middle and primary schools classroom, comprise: the jack type liftable desk in a kind of students in middle and primary schools of being exclusively used in classroom, comprise: desktop, table bucket and 2 table pin, it is characterized in that between table pin and table bucket, being provided with lowering or hoisting gear, this lowering or hoisting gear is made up of scissors jack, load-bearing axle, 2 elevating levers and 2 sleeves, elevating lever is located in the sleeve, the load-bearing axle is connected with sleeve, and be positioned at the sleeve inboard, described sleeve is connected with the table pin, described scissors jack top is connected with the table bucket, and scissors jack bottom is connected with the load-bearing axle.Scissors jack power input shaft in the lowering or hoisting gear on being located at a scissors jack power input shaft in the lowering or hoisting gear on the table pin and being located at another pin is connected by toggle.
After adopting such structure, the jack type liftable desk is characterised in that: the rotation of scissors jack power input shaft drives the lifting of scissors jack; And the lifting of scissors jack has driven the lifting of elevating lever; The weight that the load-bearing axle is used to bear the scissors jack is connected with scissors jack bottom; The load-bearing axle links to each other with sleeve again, places the sleeve inboard, makes not coplane of scissors jack and sleeve, and elevating lever lifting simultaneously before and after making.Toggle is enclosed within on the scissors jack power input shaft of both sides, thereby makes the lifting simultaneously of both sides scissors jack, and then causes the lifting of desk.Adopt each scissors jack of both sides, can effectively utilize a following space; The jack type liftable desk can be accomplished both sides lifting simultaneously simultaneously, thereby the student can carry out the desk lifting quickly and easily.
