Detailed Description

In order to more clearly illustrate the present invention, embodiments of the present invention are further described below with reference to the accompanying drawings.

Example one

As shown in fig. 1-3, a desk capable of being quickly converted into a bed comprises a first desk 1 and a second desk 3, wherein each of the first desk 1 and the second desk 3 comprises a desktop and legs 6, and the desktop is fixedly connected to the legs 6; first desk 1 with second desk 3 unilateral rigid coupling is by dead lever 2 from the side, bed board 4 in the middle of first desk 1's back is articulated, middle bed board 4 after expanding can with the desktop coplane of second desk 3, and the desktop of first desk after the coplane, the desktop of second desk and middle bed board 4 form smooth bed board together to as the upper berth, the total length of upper berth is the width of two desks and adds the distance between two desks.

The desktop of the first desk, the desktop of the second desk and the middle bed board can be combined together to form an integral bed board as an upper berth. Preferably, the hinge point of the lower bed plate, the first desk and the second desk is arranged on the desk legs.

The fixing rod fixedly connects the first desk and the second desk and can ensure the stable structure of the first desk and the second desk, so that a stable upper berth can be formed between the fixing rod and the middle bed board.

The side surfaces of the first desk and the second desk are hinged with a foldable lower bed plate, and the lower bed plate can be flatly paved on the ground after being unfolded; to form the lower berth.

The length of the lower bed plate is from the front of the first desk to the back of the second desk.

The normal desk is 400mm, the distance between the two desks is not less than 600mm, the length of the lower bed plate is not less than 1400mm, and the desk can be used by students with the height not more than 1.4 m.

As shown in fig. 4 and 5, the middle bed board fixing device is a pin hole and a telescopic pin, the pin hole is arranged on the second desk, and the telescopic pin is arranged on the middle bed board. The telescopic pin is provided with a pull-back device, and the pull-back device can pull the telescopic pin to retract into the middle bed plate, so that the middle bed plate is separated from the second desk to be folded behind the first desk.

Preferably, the non-hinged end of the lower bed board and the joint part of the table legs are provided with table leg fixing devices, and the table legs can be firmly connected with the lower bed board by the table leg fixing devices, so that the stability of the table legs is ensured, the stability of the desk is ensured on the whole, and the condition that the upper berth is unstable due to the shaking of the desk is avoided.
