Description
Technical field
The utility model relates to a kind of desk, and specifically a kind of multifunctional lifting folds drawing table.
Background technology
The student with advancing age, height constantly increases, and the drawing table of most schools remains highly fixing drawing table, can not regulate according to student's different heights, causes myopia and hunchback easily, and is very harmful to student's health.For the adult, height also has nothing in common with each other with the custom of drawing.Therefore design a kind of multifunctional lifting that is fit to extensive crowd's use and fold very necessity of drawing table.Existing same table kind is more, and one type is to regulate the height of desktop through liftable column, and has fastening bolt to position.It has regulate inaccurate, the shortcoming of effort relatively; And in use, be prone to the sliding dental phenomenon of bolt, and cause the unsettled phenomenon of location height not firm, desk to occur, be that the utility model patent of CN87208863U just belongs to this type of like notification number.Another kind of is the height of regulating desktop through the lowering or hoisting gear of worm and gear; It has solved above-mentioned desk and has regulated inaccurately, in use is prone to the sliding dental phenomenon of bolt, causes to occur that the location is not firm, the height problem of unstable of desk; But the lowering or hoisting gear of this worm and gear has the shortcoming that adjusting is relatively required great effort, cost is high; And efficient is low especially, and often worm and gear rotates tens circles, regulates highly just several centimeters; As Granted publication day be December 26 calendar year 2001, Granted publication number just belongs to this type of for the utility model patent of CN2466972Y.Also have one type of lowering or hoisting gear that only adopts gear and tooth bar to regulate the height of desktop, it has the not firm shortcoming in location, occurs desktop easily and falls automatically.Now many is to adopt pressure liftable, and it has advantage easy to adjust, but its same not firm shortcoming in location that exists occurs desktop easily and falls automatically, and very easily damages.The inventor has applied for that in 2004 but a kind of denomination of invention is free lifting and the utility model patent of freely adjusting the learning desk of angle; Its patent No. is ZL200420017302.1; It thoroughly solved adjusting that the said goods exists relatively require great effort, regulate inaccurate, the problem that desktop falls automatically appears easily, and the desktop angle can freely be adjusted.But it has the adjusting angle inconvenience, the shortcoming that can not fold.Therefore carry and carry inconvenience, inconvenience need be carried out painter's use out of doors.
Summary of the invention
The utility model technical problem to be solved is exactly the defective to existing drawing table, provides a kind of multifunctional lifting to fold drawing table, and it can go up and down and fold, and can be with the drawing board fixation, the convenient drawing.
The technical scheme of the utility model is achieved in that it comprises underframe, is fixed with bracing frame through movable axis on the underframe, is fixed with carriage on the bracing frame; It is characterized in that: described bracing frame comprises two parallel support bars, and the lower end of support bar is fixed on the front end of underframe through movable axis, and the upper end of support bar is connected with carriage through movable axis; The stage casing of support bar is connected with folding strut through movable axis, and the bottom of folding strut is fixed on the rear end of underframe through movable axis, is fixed with jam plate respectively on two parallel support bars; All have chute on two jam plates; Be connected with sleeve pipe between two jam plates, the activity of sleeve pipe two ends is contained in the chute, and the sleeve pipe two ends are fixed with two slip struts; Two slip struts flexibly connect with the carriage both sides respectively, and an end of sleeve pipe is fixed with eccentric wheel handle through pivot pin.
The utility model technical scheme preferably is: the front end of described carriage is fixed with Movable bracket through movable axis, and Movable bracket bottom center fixed has telescopic strut, and the other end of telescopic strut is fixed on the carriage; Described Movable bracket is fixedly connected by two orthogonal fixed bars; On the described Movable bracket drawing board is housed.Described eccentric wheel handle comprises a handle, and the front end of handle is provided with a semi-circular runner, and the eccentric position of runner has axis hole, and axis hole is fixed on the pivot pin of sleeve pipe; Locking bar is equipped with in activity in the described sleeve pipe.
The utility model delicate structure, it utilizes two aspects to make fan shape moving and cooperatively interacts significantly up-down synchronously about realization; And can fold, it regulates more laborsaving, and fixation; Easy to carry, low cost of manufacture especially is fit to the open air and carries out painter's use.
