Abstract

The utility model discloses a set of lifting desk and chair, which comprise desk legs, a drawer and a desktop board, wherein the drawer and the desktop board are positioned upon the desk legs. The desk and the chair is characterized in that: springs and rising tubes are mounted in the desk legs; and the rising tubes, which are positioned upon the springs, are provided with a plurality of holes corresponding to the external desk legs in which bolts are inserted to fix the heights of the desk and the chair. The bolt is a wooden stick. After the technical scheme is adopted, the heights of the desk and the chair can be adjusted according to the stature of a student; during the adjustment, if the desk and the chair are not high enough, the bolts are first pulled out, the springs in the desk legs lose resistance and therefore spring up, and after the springs spring up to an appropriate height, the bolts are inserted in the holes corresponding to the desk legs and the rising tubes, so that the desk and the chair are fixed at the height; if the desk and the chair are too high, the bolts are first pulled out likewise, the desktop board is pressed down, the springs are also pressed down along, and after an appropriate height is reached, the bolts are inserted into the holes corresponding to the desk legs and the rising tubes, so that the desk and the chair are fixed at the height.

A kind of up-down desk and chair

Technical field

The utility model relates to a kind of up-down desk and chair.

Background technology

Now the tables and chairs in the classroom can not be regulated height mostly, science not so very, the student increases fast in this age height, tables and chairs also must be along with the variation of student's height change in elevation.So, some height-adjustable tables and chairs have appearred on the market, have electronic, have to pull, volume is bigger, and it is cumbersome that many part machineries will be installed, and the price of such cover tables and chairs is expensive more many than common tables and chairs, has therefore limited the utilization of these adjustable-height tables and chairs.

Therefore design a kind of simple in structurely, up-down desk and chair easy to operate and that price is economical seems especially important.

The utility model content

Technical problem to be solved in the utility model provides a kind of up-down desk and chair, and this up-down desk and chair is simple in structure, and is easy to operate and price is economical.

Technical problem to be solved in the utility model can be achieved through the following technical solutions:

A kind of up-down desk and chair, the drawer and the desktop that comprise a pin and table pin top, it is characterized in that, in the described table pin spring and increased pipe are housed, this increased pipe is positioned at described spring top, increased pipe is provided with the corresponding hole of a plurality of and outside table pin, so that a latch inserts wherein, fixes the height of these tables and chairs.

Described latch is a wooden stick.

After adopting above technical scheme, just can raise and regulate the height of tables and chairs according to the student, when regulating, if tables and chairs are not high enough, earlier latch to be extracted, the amount spring has not had resistance in the table pin, just bullet get on, after being bound to suitable height, latch is inserted in the hole of table pin and fall way correspondence, tables and chairs can be fixed on this height; If tables and chairs are too high, extract latch equally earlier, to pressing down desktop, spring also thereupon to pressing down, after arriving a proper height, inserts latch in the hole of table pin and fall way correspondence, tables and chairs can be fixed on this height.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

A kind of up-down desk and chair, the drawer 2 and the desktop 3 that comprise a pin 1 and table pin 1 top, it is characterized in that, described table pin is equipped with spring 11 and increased pipe 12 for 1 li, this increased pipe 12 is positioned at described spring 11 tops, increased pipe 12 is provided with the corresponding hole of a plurality of and outside table pin, so that a latch 4 inserts wherein, fixes the height of these tables and chairs.

Described latch 4 is a wooden stick.

After adopting above technical scheme, just can raise and regulate the height of tables and chairs according to the student, when regulating, if tables and chairs are not high enough, earlier latch 4 to be extracted, the spring 11 in the table pin 1 has not had resistance, just bullet get on, after being bound to suitable height, latch 4 is inserted in the hole of table pin 1 and fall way 12 correspondences, tables and chairs can be fixed on this height; If tables and chairs are too high, extract latch 4 equally earlier, to pressing down desktop 3, spring 11, inserts latch 4 in the hole of table pin 1 and fall way 12 correspondences after arriving a proper height also thereupon to pressing down, and tables and chairs can be fixed on this height.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
