Description

A kind of adjustable for height lift tables and chairs

Technical field:

The utility model relates to students' supplies, is specifically related to a kind of adjustable for height lift tables and chairs.

Background technology:

School's desk and chair used is the using appliance that the students in middle and primary schools in growth and development stage can not or lack, and highly whether the use of desk is suitable for the different age and with the age but the student of different height use, then whether the students in middle and primary schools in the growth and development stage that concerns have physiology and the psychological development environment of an ideal health.If the collocation of desk and chair height is not suitable for, caused the sitting posture of student's upper class hour bad, form askew the bad habits such as health, then affect figure for a long time, cause myopia, so need a kind of technology not enough to make up this on the market.

Utility model content:

In order to solve the problem, the utility model provides a kind of technical scheme: a kind of adjustable for height lift tables and chairs, comprise tables and chairs body, interior fall way, outer fall way, lower bottom base and leg, described interior fall way is fixedly connected on the center of tables and chairs body lower surface, described interior fall way is flexibly connected in the internal chamber of fall way outside, described outer fall way is fixedly connected on the center of lower bottom base upper surface, described leg is two, with a left side, the mode of right symmetry is fixedly connected on the two ends of lower bottom base bottom surface, its innovative point is: also comprise locking device, described locking device is fixedly connected with outside on fall way sidewall, the sidewall of described interior fall way is provided with several through holes, the concrete structure of described locking device is: comprise bearing pin, spring, axle sleeve and knob, described axle sleeve main body is the tubing of hollow, and tubing outer round surface is provided with screw thread, and described axle sleeve is fixedly connected with on the sidewall of fall way outside by screw thread, described bearing pin is slender axles, and described knob is mountain font, and described bearing pin is together with knob global formation, described bearing pin is embedded in the through hole of interior fall way and outer fall way, and described knob is movably connected on the outer round surface of axle sleeve by screw thread, described spring is coated on the outer round surface of bearing pin.

As preferably, the through hole number on described interior fall way sidewall is 4.

As preferably, described spring is disk spring.

The beneficial effects of the utility model: its reasonable in design, modern design is unique, simple to operate, easy to use, arranging 4 through holes to the height regulating tables and chairs successively, can be arranged disk spring and can ensure enough deformation forces, screw thread is adopted to connect between parts, facilitate the installation at initial stage, also facilitate the maintenance in later stage, lower replacement cost.
