Utility model content

(1) Technical problems solved

Aiming at the deficiencies of the prior art, the utility model provides a desk and chair capable of lying down and sleeping, which has the advantages of protection, and solves the problem that the existing desk and chair capable of lying down and sleeping does not have the protection function.

(2) Technical solutions

In order to achieve the above purpose, the utility model provides the following technical solutions: a desk and chair for lying down and sleeping, including a main body assembly;

The main assembly includes a frame body 1, a seat cushion, a frame body 2, a back pad, a headrest, a switch and a tripod; the seat pad is provided on the top of the frame body 1, and the frame body is provided on the top of the frame body 1 Second, the back pads are arranged on the two sides of the frame body, the headrest is arranged on the top of the frame body 2, the switch is arranged on the frame body 1, and the switch is arranged on the frame body 1 A tripod, a table body assembly is arranged on the left side of the first frame body, and an adjustment assembly is arranged on the first frame body;

The adjusting assembly includes a casing, a slider, a rod body, a plate body, a groove body, a groove body 2, and a plate body 2; the frame body 1 is provided with the casing on the front surface, and the casing slides inside The first slider is connected, the top of the slider is provided with the rod body one, the top of the rod body is provided with the plate body one, and the outer side wall of the rod body is provided with a plurality of the groove body one, so The second groove body is provided on the side of the casing, and the second groove body is connected to the second plate body in rotation.

Preferably: one of the board bodies is a board with curved edges and corners.

By adopting the above solution, the user can be prevented from being hurt at one corner of the board body, and the device can be contacted with the user through a smooth arc, thereby improving the safety of the device.

Preferably: the top of the casing is provided with a sliding assembly; the sliding assembly includes a sliding groove, a second sliding block, a second rod body, a first spring and a third plate body; the inner top surface of the casing is provided with the sliding groove, so The sliding groove is slidably connected to the second sliding block, the second sliding block is provided with the second rod body, one end of the second rod body penetrates the inner side wall of the casing, and the third plate body is installed on the second rod body At one end, the first spring is disposed between the bottom of the second sliding block and the casing.

By adopting the above solution, when the rod body slides upward, the groove body 1 drives the plate body 2 to rotate, so that the plate body 2 is in contact with the bottom surface of the plate body 3 when it rotates, and generates a thrust on the plate body 3, so that the plate body 3 rotates. Slide up, the third plate body slides up and drives the rod body 2 to slide upward, so that the rod body 2 slides up and drives the slider 2 to slide up, and pulls the spring 1, the chute restricts the slider 2 to slide longitudinally, until the rod body 1 slides upwards. After the height is adjusted and suitable, the rod body 1 can be gradually loosened, so that the rod body 1 slides down by its own gravity until the plate body 2 is inserted into the groove body 1 on the rod body 1, and the rebound force of the spring 1 pushes the slider 2 to slide down.
