Description

A school desk with adjustable angle for convenient storage

technical field

The utility model relates to a desk, in particular to a desk with an adjustable angle for convenient storage.

Background technique

Desks are school learning desks. Because the space of the desk itself is too large, the space that can be provided to students for activities and cleaning after class is limited, which is very inconvenient. Moreover, the desktops of existing desks are all flat and have fixed angles. Such desks will make students more prone to fatigue. For students who use computers to draw pictures, the edge of the horizontal desktop often touches the wrist, which is unavoidable when working for a long time. It will reduce the learning efficiency. And the existing classroom desk is also inconvenient to carry, generally needs two people.

Utility model content

In order to solve the above problems, the utility model provides a convenient storage and adjustable angle desk, which not only can reduce the space occupied by the desk during after-school activities and cleaning, but also can adjust the angle of the desktop, and one person can Very convenient to carry.

The technical solution adopted by the utility model to solve the technical problem is: a desk with an adjustable angle for easy storage, which includes a desktop, a bolt-type rotary telescopic mechanism installed at the bottom of the desktop, and a table frame connected between the table top and the table frame The three-speed positioning mechanism, the drawer, and the connecting rod connected between the desktop and the drawer.

The bolt-type rotating telescopic mechanism installed at the bottom of the desktop includes a box, a universal lock structure, a gear, a rack, and a rod. The length of the sliders at both ends of the lock can be adjusted by turning the key on the universal lock, and the rods at both ends of the cooperation mechanism can be properly embedded in any one of the three gears set on the third gear positioning mechanism to adjust the desktop angle.

The third gear positioning mechanism connected between the table top and the table frame is fixed between the table top and the table frame by bolts, and at this time, the table top can be turned freely with the bolts as the axis.

The connecting rod connected between the desktop and the drawer is connected with the desktop and the drawer through a hinge, so as to realize the linkage between the desktop and the drawer.

Compared with the prior art, the utility model has the beneficial effects as follows: the utility model adopts a bolt-type rotary telescopic mechanism and a third-gear positioning mechanism, so that the desktop panel can be positioned at three different angles; the desktop and the drawer are linked through a connecting rod, The desktop and the drawer can be shrunk synchronously; the cost is low, the operation is simple, the space occupied after shrunk is small, easy to carry, reliable and practical.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a partially enlarged schematic diagram of the third gear positioning mechanism of the present invention.

Fig. 3 is a schematic diagram of the internal structure of the bolt-type rotary telescopic mechanism of the present invention.

Figure 4 is a schematic view of the utility model fully contracted.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

In Fig. 1-4, 1 pin-type rotary telescopic mechanism, 2 desktop, 3 third gear positioning mechanism, 4 table frame, 5 connecting rod, 6 drawer, 1-1 box, 1-2 universal lock structure, 1-3 rack , 1-4 gears, 1-5 bars.

It can be seen from the figure that the third gear positioning mechanism 3 is fixed between the tabletop 2 and the table frame 4 by bolts, and the tabletop 2 can be turned freely around the bolts as the axis. Connecting rod 5 is connected with desktop 2, drawer 6 by hinge. The bolt-type rotary telescopic mechanism 1 is installed at the bottom of the desktop 2, and the length of the rods 1-5 at both ends of the bolt-type rotary telescopic mechanism 1 can be adjusted by turning the key on the universal lock structure 1-2, and is properly embedded in the third gear positioning mechanism 3 Any one of the three gears set can be used to adjust the desktop angle. When the two ends of the bolt-type rotary telescopic mechanism 1 at the bottom of the desktop 2 shrink, the drawer 6 can be linked with the desktop 2 and put down together with the desktop 2 to achieve the function of accommodating the desktop 2 and the drawer 6 .
