Description

Technical Field

[0001] This utility model relates to the field of school desks and chairs, specifically an adjustable desk and chair for lunch breaks. Background Technology

[0002] Lunch break is essential for teenagers, but due to limited classroom space, students often have to nap on their desks. While this provides some rest, it can negatively impact their health, causing back pain, numbness in the hands and feet, and even cervical spine deformities.

[0003] To address this issue, existing technologies modify existing desks and chairs to allow the chairs to be adjusted to a reclining position, enabling them to function as a nap area. To accommodate the chair angle adjustment, the desk height is also adaptively adjusted to minimize interference during chair adjustments and ensure that users' feet do not interfere with the desktop. This approach improves classroom resource utilization and solves the aforementioned problems.

[0004] Specifically, a rotating, self-returning, adjustable student desk and chair for lunch break, as described in patent application number 202122840774.3, allows students to lie down and sleep comfortably by rotating the footrest and backrest during lunch break. The backrest position is adjusted by adjusting the chair post through an adjustment mechanism, and the force of the adjustment mechanism is achieved through an external handle (each set of desks and chairs comes with at least one handle, which is kept by the student). However, due to the obstruction of the desk, it is difficult for students to stretch their legs, which still affects their lower limbs.

[0005] The present invention aims to solve the technical problems existing in the prior art. To this end, an adjustable lunch break desk and chair is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable desk and chair for lunch breaks to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable lunch break desk and chair includes a base, a protrusion fixedly connected to one side of the base, a desk support assembly rotatably connected to the protrusion, and a desk tabletop assembly fixedly connected to the other end of the desk support assembly.

[0009] The base is rotatably connected to an adjustment mechanism, the other end of which is rotatably connected to a desk support assembly. The desk panel assembly is rotatably connected to a reinforcement device, which works in conjunction with the adjustment mechanism.

[0010] As a further embodiment of this utility model: the desk support assembly includes a support rod, which is rotatably connected to a protrusion. The other end of the support rod is rotatably connected to a mounting base, and the other end of the mounting base is connected to the desk tabletop assembly. The mounting base is rotatably connected to a reinforcing device, and the support rod is fixedly connected to a connecting rod, which is rotatably connected to an adjustment mechanism.

[0011] As a further embodiment of this utility model: the desk panel assembly includes a desk panel one, which is fixedly connected to the mounting base. A desk panel two is provided on one side of the desk panel one, and a louver is provided on one side of the desk panel one. The desk panel one is rotatably connected to the desk panel two through the louver.

[0012] As a further embodiment of this utility model: the reinforcing device includes a reinforcing rod, which is rotatably connected to the mounting base, and the other end of the reinforcing rod is rotatably connected to the base. The reinforcing rod has several insertion holes, and a fixing bolt is provided on one side of the reinforcing rod.

[0013] As a further embodiment of this utility model: the adjustment mechanism includes a slider and a handle. The slider is slidably connected to the base. A guide groove is provided on one side of the base. The slider is located in the guide groove. A connecting block is fixedly connected to one side of the slider. An adjustment rod is rotatably connected to the connecting block. The other end of the adjustment rod is rotatably connected to the connecting rod. A fixing bolt passes through the adjustment rod and is threadedly connected to the adjustment rod. The handle is rotatably connected to the base. A threaded rod is fixedly connected to one end of the handle. The threaded rod passes through the slider and is threadedly connected to the slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, rotating the handle drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the slider, the rotation of the threaded rod drives one end of the slider. The slider then drives the lower end of the adjusting rod to move through the connecting block. The upper end of the connecting block drives the support rod to swing, that is, the support rod drives the mounting base to descend, and the mounting base drives the first and second desk panels to descend. When the first and second desk panels descend to the fixed position, the slider moves to the rightmost end of the guide groove, and the height of the first desk panel is level with the seat cushion. Then, by rotating the louvers, the second desk board can be unfolded together with the first desk board. The second desk board, the first desk board, and the seat cushion and backrest of the chair can then form a bed, making it convenient for students to lie down and sleep. At the same time, the device is equipped with a fixing bolt, that is, when the first desk board is raised to the highest point to form a desk, and lowered to the lowest point to form a bed, the reinforcing rod is connected to the adjusting rod through the fixing bolt to strengthen the support of the first desk board. The device can fold the desk, so that the desk and chair can form a bed, allowing students to lie down and sleep. Attached Figure Description
