Description

Extensible desk

Technical Field

The utility model relates to a teaching equipment field specifically indicates an extensible desk.

Background

The desk in the school is a common teaching tool, the existing desk is generally used for placing articles such as books on a drawer and a desk, but sometimes the articles such as books cannot be placed on the desk and in the drawer, some students can place the articles on the ground, and therefore the desk is inconvenient, and the extensible desk is designed for the situation.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to overcome the defects of the above technology and provide an extensible desk.

In order to solve the technical problem, the utility model provides a technical scheme is an extensible desk: comprises a desk body and extension mechanisms symmetrically arranged at two sides of the desk body;

the extension mechanism comprises a support plate, an L-shaped support rod, a first sleeve and a second sleeve, wherein the first sleeve is symmetrically arranged at the side end of the desk body, one end of the support plate is rotatably connected with the two first sleeves, limiting grooves are symmetrically arranged on the support plate, the second sleeve is symmetrically arranged on one side of the desk body, one end of the L-shaped support rod is arranged in the second sleeve and is rotatably connected with the second sleeve, the other end of the L-shaped support rod is provided with a limiting block, and the limiting block is matched with the corresponding limiting grooves.

As a refinement, the second sleeve is located below the first sleeve.

As an improvement, first magnets are symmetrically arranged on two sides of the desk body, second magnets are symmetrically arranged at the upper end of the supporting plate, and the second magnets are matched with the first magnets.

As an improvement, a baffle is arranged at one end of the L-shaped supporting rod, which is rotatably connected with the second sleeve.

Compared with the prior art, the utility model the advantage lie in: when the desk is not used, the supporting plate can be upwards rotated to be parallel to the side face of the desk body, the second magnet is matched with the first magnet, and therefore the supporting plate can be folded.

Detailed Description

The following describes the extendable desk of the present invention in further detail with reference to the accompanying drawings.

With reference to the attached figures 1-6, an extensible desk comprises a desk body 1 and extension mechanisms symmetrically arranged on two sides of the desk body 1;

extend the mechanism and include backup pad 2, L type bracing piece 3, first sleeve 4 and

second sleeve

5, 4 symmetries of first sleeve set up at 1 side of desk body, the one end and two first sleeve 4 of backup pad 2 rotate to be connected, the symmetry is equipped with spacing groove 6 in the backup pad 2, 5 symmetries of second sleeve set up in 1 one side of desk body, the one end setting of L type bracing piece 3 just rotates with second sleeve 5 in second sleeve 5 to be connected, the other end of L type bracing piece 3 is equipped with stopper 7, stopper 7 and the 6 cooperations of spacing groove that correspond.

The second sleeve 5 is located below the first sleeve 4.

First magnets 8 are symmetrically arranged on two sides of the desk body 1, second magnets 9 are symmetrically arranged at the upper end of the supporting plate 2, and the second magnets 9 are matched with the first magnets 8.

And a baffle plate 10 is arranged at one end of the L-shaped support rod 3 which is rotatably connected with the second sleeve 5.

The utility model discloses when concrete implementation, during the use, at first rotate backup pad 2, make backup pad 2 adjust into the horizontality, then stopper 7 and the spacing groove 6 cooperation in backup pad 2 of 3 one ends of L type bracing piece, at this moment backup pad 2 just can fix at the horizontality, just can place article in backup pad 2, when not using, can upwards rotate backup pad 2, make second magnet 9 and first magnet 8 cooperation, at this moment backup pad 2 just can be fixed to desk body 1.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
