Description
Technical field
The utility model relates to a kind of desk, relates in particular to a kind of fast lifting desk.
Background technology
As everyone knows, at present, the desk and chair that primary school is used, it is mostly fixed dimension structure, from first grade of primary school to senior middle school three grades, reached for 12 years, the desk of their practicality (chair) height dimension does not have to change substantially, and student's stature grows tall year by year, the requirement that the stature that is far from suitable constantly grows tall.
The desk and chair that school is used now, the one, the wooden tables and chairs of fixed dimension, another kind be can lifting ironware table pin add the tables and chairs of wooden desktop, after this, a kind of structure table (chair) is except desktop, divide two sections, table leg and table pin, two sections of many holes that are provided with identical distance, are fixed through two sections of sockets with bolt.If want lifting, extract bolt with cutting pliers or Adjustable wrench, take apart and elongate two sections, then socket again, this lifting is very difficult.Almost each school does not all organize workman to go specially lifting, and after in fact student's stature grows tall year by year, the height of table (chair) fails to regulate year by year rising.
Chinese patent 201110239349 .7 disclose 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 are affixed with screw, 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, with bolt, connects table leg; 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 rectangle steel pipe is provided with a microscler inclined hole by the outside of upper part, 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 lifting stops, and motion bar is got back to again origin-location, has stoped table pin epimere to glide.As long as operator holds desktop dual-side along upwards carrying, can rise, rise and once only need several seconds.When desktop declines, only desktop need be turned forward, the motion bar in oblique slotted hole skids off sawtooth, and motion bar rests on the lower of oblique slotted hole, then table is returned to origin-location and to end, clicks desktop again, at once declines.But, cumbersome when it exists and adjust to decline, and outside lifting structure is exposed to, when primary and secondary students' drive by curiosity goes down to stir, easily produce misoperation, even hurt student.While rising in addition, promote too much, a table pin epimere will be separated with table underfooting section.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of simple in structure, cheap, easy to operate, safe and reliable fast lifting desk.Its concrete technical scheme is: fast lifting desk comprises desktop, table leg, table pin epimere, table underfooting section, table pin epimere connecting rod, table underfooting section connecting rod, table underfooting Duan Weiyi rectangle square steel, its short end inwall is welded with a long iron plate, the nearly middle part of long iron plate is connected with a flute profile ironware, on flute profile ironware, there are two symmetrical microscler inclined holes, two motion bars are loaded on respectively in two microscler inclined holes, table pin epimere is the rectangle square steel with strip breach, its short end inwall is welded with a fixed iron piece, an affixed stationary saw gear piece on fixed iron piece, on stationary saw gear piece, pass through the cordwood saw gear piece of the movable through hole of the overlapping hinged middle part band of rivet, there is a box-shaped handle upper end of cordwood saw gear piece, box-shaped handle is through the adjusting hole in table leg side, strip breach is positioned at the offside of sawtooth sheet fixed iron piece.
During for fear of rising, table pin epimere is separated with the generation of table underfooting section, and the bottom of stationary saw gear piece is provided with a lug boss, and lug boss is than the wide 5mm of sawtooth sheet.
Said sawtooth sheet, its saw kerf length is 8 mm, is spaced apart 7 mm between saw kerf.
Said cordwood saw gear piece, the movable through hole length at its middle part is 12 mm.
Its angle of inclination of said microscler inclined hole is 20 °-40 °
Said motion bar one end is hold-doun nut, and the other end is movable nut.
From the technical solution of the utility model, can find out, because can inserting And in the rectangle steel pipe of a underfooting section, table pin epimere can slide up and down, two blade saw gear pieces of table pin epimere insert in the flute profile ironware of table underfooting section while assembling, motion bar in flute profile ironware just slips in sawtooth mouth naturally, and this has just stoped table pin epimere to whereabouts.As long as hold desktop edge, upwards carry, sawtooth inclined-plane is released motion bar outside sawtooth, then falls into again in lower tooth, has stoped table pin epimere to fall, lattice just desktop rises, by that analogy.If desktop is declined, as long as hold desktop edge and square handle, upwards slightly mention, 7 mm just cordwood saw gear piece rises, now motion bar is discharged from outside tooth, and fixed teeth is all sealed, and then transfers desktop, and desk has just declined.
The utility model compared with prior art has following advantage:
1, desk lifting structure Hide All is in upper and lower section of table pin, and student touches less than the inclined hole in structure and motion bar, is conducive to safety, seems also comparatively attractive in appearance simultaneously.
2, the flute profile ironware in lifting structure, is designed to symmetrical diplopore and dual-active lever, better than being designed to single hole and single pole, because only have movable single pole, just in case operator is slightly improper, just likely landing is less than tooth mouth for single pole, and rising will be obstructed.Be designed to symmetrical diplopore and dual-active lever just can be avoided the phenomenon of being obstructed, and to increasing Strong desk stability, prevent from waving and also have certain effect.
3, operation is very easy, and rise and fall are quick.Operator is only with just accomplishing several seconds.And also having played table pin epimere while avoiding rising, the lug boss of stationary saw gear piece produces separated effect with table underfooting section.Above-mentioned design simultaneously is also applicable to tablet chair.
