Description
Technical field
The utility model relates to a kind of desk, particularly relates to a kind of lifting desk.
Background technology
As everyone knows, at present, the desk and chair that primary school uses, it is mostly fixed dimension structure, from first grade of primary school to senior middle school's Third school grade, reached for 12 years, desk (chair) height dimension of their practicality does not change substantially, and student's stature grows tall year by year, the requirement that the stature that is far from suitable constantly grows tall.
Chinese patent 201110239394.7 discloses a kind of liftable student's desk, it comprises desktop, table leg, table pin epimere, table underfooting section, table pin epimere connecting rod, table underfooting section connecting rod, desktop and table leg screw affixed, table leg is provided with the hole of two different distance, table pin epimere is grooved steel pipe, upper end is provided with two holes, connects table leg with bolt; Lower end channel-section steel pipe is two gang saw teeth.Table underfooting section is rectangle steel pipe, and table pin epimere is socketed among a underfooting section, and the outside of the top end portion of rectangle steel pipe is provided with a microscler inclined hole, is provided with a motion bar in inclined hole.When table pin epimere upwards promotes, motion bar is released by the sawtooth of table pin epimere, and promote and stop, motion bar gets back to origin-location again, prevents a pin epimere to glide.As long as operator holds desktop dual-side along upwards carrying, can rise, rising and once only needing a few second.When desktop declines, only desktop need be turned forward, the motion bar in oblique elongated hole skids off sawtooth, and motion bar rests on the lower of oblique elongated hole, then table is returned to origin-location and clicks desktop to end again, at once decline.But it also exists when adjustment declines cumbersome, and outside lifting structure is exposed to, when primary and secondary students' drive by curiosity goes down to stir, easily produces misoperation, even hurt student.Also have when rising and promote too much, table pin epimere will be separated with table underfooting section.And the height of each lifting limits by zigzag intervals, can not continuous setup, also there is the higher problem of manufacturing cost in addition.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of structure simple, cheap, easy to operate, height continuously adjustabe, safe and reliable lifting desk.Its concrete technical scheme is: lifting desk comprises desktop, table case, sole, table pin epimere, table underfooting section, table underfooting section connecting rod, adjusting rod, in the section of table underfooting, under have a rectangular boxes, lower square frame is fixed on sole, upper square frame, its inwall of length direction of lower square frame is welded with a long iron plate, the nearly middle part of long iron plate is provided with screw hole and regulates rod aperture, the affixed rope nail in nearly bottom of long iron plate, activity template is embedded with in the width of lower square frame, table pin epimere is a rectangle square steel, rectangle square steel lower end width direction is connected with U-shaped circle bar, a rising circle bar is connected with between two U-shaped circle bar bottoms, rectangle square steel on lower side on length direction between be connected with the circle of falling-rising bar, one rope I one end is fixed on adjusting rod, the other end is affixed with rising circle bar after being wound in the sleeve be set on two screws, one rope II one end is fixed on adjusting rod, the other end is fixed on decline circle bar, one rope III one end is fixed on adjusting rod, the other end is around in rope by the space Hou Chan of activity template and nails on.
For the ease of rotary regulating lever, the middle part of adjusting rod is provided with a regulating handle.In order to make rope III can not retract in a underfooting section easily, the afterbody of rope III is provided with a weight.
In order to reduce rope I and the friction of rising circle bar, rising circle bar is set with a sleeve.
When using lifting desk of the present utility model, first insert in the section of table underfooting by table pin epimere, screw limit is inserted by fastening for sleeve set rear nut on screw in limit, fastening after loading adjusting rod, dial on two activity templates, three ropes are connected on request and just can employ.When needing to make desk increase, unclamp the rope III being wrapped in and restricting and nail on, be rotated counterclockwise adjusting rod, table pin epimere rises under the acting in conjunction of adjusting rod, sleeve, rope I, rising circle bar.When needing desk is declined, unclamp the rope III being wrapped in and restricting and nail on, turn clockwise adjusting rod, and desk just have dropped.
As can be seen from the technical solution of the utility model, because table pin epimere can insert in a underfooting section, and can slide up and down, when needs make desk rise, unclamp the rope III being wrapped in and restricting and nail on, be rotated counterclockwise adjusting rod, table pin epimere rises under the acting in conjunction of adjusting rod, sleeve, rope I, rising circle bar.When needing desk is declined, unclamp the rope III being wrapped in and restricting and nail on, turn clockwise adjusting rod, and desk just have dropped.Simply make use of the principle of rural area winch spool well-digging water, so structure is simple, the manufacturing equipment of use is also simple, nature cost has just declined to a great extent, fully meet the utility model structure simple, cheap, easy to operate, height continuously adjustabe, safe and reliable goal of the invention.
