Description

Directly lifting school desk and chair for students

Technical Field

The utility model relates to a student desk and a chair, in particular to a student noon break desk and a chair which are directly lifted.

Background

Because students have different heights, in order to adapt to the heights of different students, the student desk and chair is usually designed into a structure capable of being adjusted in a lifting manner. The traditional lifting adjusting structure is characterized in that fixing plates are arranged on two sides of a book hopper and a chair plate, more than two lifting adjusting holes are formed in the fixing plates, fixing holes are formed in a table supporting leg and a chair supporting leg, the lifting adjusting holes of the fixing plates are fixed with the fixing holes through fasteners such as screws, and the defects of the structure are that: each time lifting and adjusting needs to be carried out, the screw is loosened and taken out by a tool, when the book hopper or the chair plate is adjusted to the required height, the screw is clamped into the corresponding lifting and adjusting hole and the corresponding fixing hole and is fixed, two persons are usually required to operate, the operation is very troublesome, and the adjusting efficiency is low. Therefore, people invented lifting desk and chair with different forms such as hand or key press, for example, chinese patent 201810876570.5, the patent name is a hand stepless lifting desk, and Chinese patent 201220109101.9, the patent name is a key type lifting desk, the desk legs and chair legs of the lifting desk and chair are divided into an upper sleeve and a lower sleeve, the upper sleeve is a large sleeve, the lower sleeve is a small sleeve, or the upper sleeve is a small sleeve, the lower sleeve is a large sleeve, the small sleeve is inserted into the large sleeve, and the lifting structure is arranged between the large sleeve and the small sleeve, although the lifting operation is more convenient, due to the structure limitation of the large sleeve and the small sleeve, the top point of the upper sleeve can only be lowered to the top point of the lower sleeve at most, namely, the position of half of the desk legs and the chair legs can only be lowered, and the lowering distance is limited.
