Summary of the invention

The object of this invention is to provide one and can be elevated student desk and chair arbitrarily, it can solve in prior art, and lifting pupil desk adjustment inconvenience and School chair can not with the problems of desk lifting.

In order to solve the problem, the technical solution used in the present invention is: lifting student's desk comprises desktop, table leg, drawer plate arbitrarily, described table leg includes cover interior pipe within the outer tube, be provided with inner conical drogue between the socket place of described outer tube and described interior pipe, outside this socket place, be provided with lock sleeve mother.

In above technical scheme, further: outside the described interior pipe of described table leg, be provided with size scale bar.

Any lifting School chair, comprises the chair back, seat, reinforcing prop and chair leg, and described table leg includes cover interior pipe within the outer tube, is provided with inner conical drogue, is provided with lock sleeve mother outside this socket place between the socket place of described outer tube and described interior pipe.

In above technical scheme, further: outside the described interior pipe of described chair leg, be provided with size scale bar.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

1, the present invention is adopted can to adjust arbitrarily the height of student's desk, chair.

2, structure of the present invention is simple, safe and reliable.

Accompanying drawing explanation

Fig. 1 is that the present invention is elevated arbitrarily student's desk front view.

Fig. 2 is the partial sectional view that the present invention is elevated arbitrarily student's desk table leg.

Fig. 3 is that the present invention is elevated arbitrarily pupil chair front view.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the present invention is further described: any lifting student's desk as shown in Figure 1 and 2, comprise desktop 4, table leg, drawer plate 5, table leg is formed primarily of interior pipe 1, outer tube 3, inner conical drogue 6 and lock sleeve female 2, outer tube 3 is provided with external screw thread, lock sleeve mother 2 is provided with internal thread, interior pipe 1 is contained in outer tube 3, and inner conical drogue 6 is contained between interior pipe 1 and outer tube 3, and interior pipe 1 and outer tube 3 are fixed by lock sleeve female 2; Size scale bar is indicated at the outer surface of interior pipe 1.

As shown in Figure 3, and be elevated arbitrarily student's desk and to match the chair used, comprise the chair back 12, seat 11, reinforcing prop 13 and chair leg, chair leg is primarily of interior pipe 14, outer tube 16 and lock sleeve mother 15 formation, and chair leg is identical with leg structure of collapsible, repeats no more; Size scale bar is indicated at the outer surface of interior pipe 14.
