Abstract

The utility model relates to an automatic elevation desk which comprises a bracket, a desk elevation frame and a desk body, wherein, an upright post of the bracket is inserted into an upright post of the desk elevation frame; a spring is arranged at the upper end of the upright post of the bracket, so that the elevation frame and the desk body can be elevated through the retraction of the spring; a spring pin is arranged inside a transverse tube of the desk elevation frame; the outer side of the spring pin is opposite to a positioning pin hole that is arranged on the bracket upright post, and the inner side is connected with a moving handle that is arranged on the desk body; a pulley that facilitates the direction changing of a rope that connects the spring pin is arranged on the desk body and inside the transverse tube of the elevation frame. The rope and the spring pin are driven by the moving handle, so that the elevation frame and the desk body can automatically ascend or descend under the effect of the spring that is arranged at the upper end of the upright post. The automatic elevation desk is characterized in that the desk can satisfy the utilization requirements of students with different height so as to guarantee the correct sitting position of the students, thereby favoring the normal growth of the students.

Description

The automatic lifting desk

Technical field:

The utility model relates to a kind of desk, specifically a kind of automatic lifting desk.

Background technology:

At present, the desk that the student uses mostly can not be adjusted height, thereby is difficult to adapt to student's use of different heights, causes sitting posture of student incorrect, and reading and writing is tired uncomfortable, has a strong impact on the normal development of student's health.

Summary of the invention:

In view of the foregoing, the purpose of this utility model provides a kind of automatic lifting desk, uses with the student who adapts to different heights, guarantees that sitting posture of student is correct, is of value to the normal development of student's health.

The purpose of this utility model is achieved in that it comprises support and desk body, it is characterized in that: between support and desk body, be provided with the desk crane, the desk body places on the desk crane, the column of support inserts in the desk crane column, column upper end at desk crane column inner support is provided with spring, by the flexible realization crane of spring and the lifting of desk body; Be provided with spring pin in the transverse tube of desk crane, this pin outside is corresponding with set dowel hole on the bracket upright post, inboard link to each other with set spanner on the desk body, on the desk body with in the transverse tube of crane, be arranged with and make the pulley that is connected the break-in of spring pin rope by rope.During use, drive rope, under the effect of pulley, spring pin is moved inward, leave dowel hole by spanner, at this moment, desk crane and desk body unclamp spanner automatically to rising, spring pin resets, and inserts in the corresponding dowel hole, and crane and desk body are fixed.If want desk crane and desk body are descended, when moving spanner, get final product to pressing down the desk body.

The utility model has the advantages that desk body liftable, the student who satisfies different heights uses, and guarantees that sitting posture of student is correct, is of value to the normal development of student's health.

Below in conjunction with accompanying drawing the utility model is done with explanation.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the side view of Fig. 1.

The specific embodiment:

By accompanying drawing as can be known, the utility model is made of support 1, desk crane 2 and desk body 3, and desk body 3 is fixed on the desk crane 2, is provided with pulley 4 in desk body 3 two sides and rotates spanner 5.Support 1 is made of four support standpipe 1-1 and two short transversal pipe 1-2, two long transverse tube 1-3, and support standpipe 1-1 is provided with a plurality of dowel hole 1-1-1; Desk crane 2 is made of four standpipe 2-1 and four transverse tube 2-2, be provided with the back-moving spring 7 and the pulley 8 of a pair of location pin 6 and each location pin below in the transverse tube, the pin 6 inboard ropes 9 that pass through in location link to each other with rotation spanner 5, pin 6 outsides, location are corresponding with dowel hole 1-1-1, and rope 9 is by pulley 8 and pulley 4 break-ins; Four support standpipe 1-1 insert respectively in four standpipe 2-1 of desk crane, and every support standpipe 1-1 is provided with spring 10.If need desk body 3 to rise, drive rope 9 by spanner 5, location pin 6 is moved to the inside, leave dowel hole 1-1-1, at this moment, desk crane 2 and desk body 3 are automatically to rising, unclamp spanner, location pin 6 resets under back-moving spring 7 effects, inserts in the corresponding dowel hole, and crane 2 and desk body 3 is fixing.If need desk body 3 to descend, when moving spanner, get final product to pressing down the desk body.Support 1 and desk crane 2 all adopt stainless steel tube to make.
