Description
Technical field
The present invention relates to a kind of desk, relates in particular to a kind of liftable student's desk.
Background technology
As everyone knows, at present, the desk and chair that the primary school uses, it mostly is the 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 of school's use 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, this a kind of structure table in back (chair) is except that desktop, divide two sections on table leg and table pin, two sections many holes that are provided with identical distance are passed socket with bolt and are fixed for two sections.If want lifting, extract bolt with cutting pliers or Adjustable wrench, to take apart and elongate two sections, socket again then, this lifting be difficulty very.Almost each school does not all organize the workman to go lifting specially, and after in fact student's stature grew tall year by year, the height of table (chair) failed to regulate year by year rising.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and provide a kind of simple in structure, cheap, easy to operate liftable student's desk.Its concrete technical scheme is: liftable student's desk 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 the grooved steel pipe, the 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 the rectangle steel pipe, and table pin epimere is socketed among the underfooting section, and the rectangle steel pipe is provided with a microscler inclined hole by the outside of upper part, is provided with a motion bar in the inclined hole.
Also can the rectangle steel pipe by the affixed U type spare in upper part, U type spare is provided with microscler inclined hole.
Its angle of inclination of said microscler inclined hole is 10 °-30 °
Said motion bar one end is a hold-doun nut, and the other end is movable nut.
From technical scheme of the present invention as can be seen, because table pin epimere can slide up and down in the rectangle steel pipe, on the section of table underfooting an oblique-shaped hole is arranged, traverse a motion bar in the hole, when table pin epimere upwards promoted, motion bar was released by the sawtooth of table pin epimere, and lifting stops, motion bar is got back to the origin-location again, has stoped table pin epimere to glide.As long as the operator holds the desktop dual-side along upwards carrying, can rise, rising once only needs several seconds.
Desktop descends also very simple, only needs desktop is turned forward, and the motion bar in the oblique slotted hole skids off sawtooth, and motion bar rests on the lower of oblique slotted hole, then table is returned to the origin-location and clicks desktop to end again, descends at once.As rising,, hold the desktop dual-side and get final product along upwards promoting just by above-mentioned way.It is simple in structure to have reached the present invention fully, cheap, easy to operate goal of the invention.
