Description

Technical Field

[0001] This utility model relates to the field of student desks and chairs technology, and in particular to height-adjustable desks for lunch breaks. Background Technology

[0002] Desks and chairs are essential teaching facilities in schools, providing students with a comfortable learning environment. Students can also store books and other items inside the desks and chairs for safekeeping. A proper lunch break is beneficial for relieving fatigue and improving learning efficiency. However, due to the limitations of classroom space and desk and chair structure, students often have to rest hunched over their desks, which not only affects comfort and the effectiveness of their nap but can also cause neck, shoulder, and lumbar discomfort over time, impacting their health.

[0003] Existing technology, patent CN216776443U, discloses a recessed desk and chair for lunch breaks, including a desk and a chair. The desk includes legs and a tabletop supported on the legs, the height of which is adjustable. The chair includes legs, a seat supported on the legs, and a backrest hinged to the rear of the seat, the height of which is also adjustable. The desk and chair can be operated between a study position and a lunch break position. In the study position, the chair is configured for a comfortable sitting posture, with the tabletop positioned above the front of the seat. In the lunch break position, the seat is raised, the backrest is tilted backward, and the tabletop is lowered to the front of the seat. While this desk can be lowered during lunch breaks, allowing students to rest their legs on the desk for comfort, students of different ages have different heights. For taller students, their legs may dangle, affecting comfort and thus the effectiveness of their lunch break. This results in a limited applicability and low practicality for the desk. Utility Model Content

[0004] This utility model proposes a height-adjustable desk for lunch breaks, which solves the problem that existing desks cannot provide comfortable leg support for students of different heights during lunch breaks.

[0005] The technical solution of this utility model is implemented as follows:

[0006] The lunch break height-adjustable desk includes height-adjustable table legs and a desktop assembly at the top. The desktop assembly includes a first tabletop connected to the table legs, and a second tabletop movably connected to the first tabletop. By changing the relative positions of the first and second tabletops, the support range of the desktop assembly is adjusted, thus providing full support for the legs of students of different heights during lunch breaks. This prevents students' legs from dangling, enhances leg comfort, and ensures a better lunch break experience.

[0007] The upper side of the first tabletop is provided with a sliding groove arranged along the front-to-back direction of the first tabletop, and the second tabletop is slidably disposed within the sliding groove. The second tabletop can slide back and forth relative to the first tabletop, changing the front-to-back length of the tabletop assembly. A slide rail is provided on the side wall of the sliding groove, and the slide rail is connected to the second tabletop.

[0008] The second tabletop has a groove. When the desk is in normal use, pens can be placed in the groove to prevent them from rolling off the second tabletop.

[0009] The upper surface of the first tabletop is flush with the upper surface of the second tabletop. This ensures that when the second tabletop is folded up, the upper surface of the entire tabletop assembly is flush, avoiding any steps and guaranteeing normal use of the tabletop assembly.

[0010] The lower side of the first tabletop is connected to a drawer. The drawer can be used to store students' belongings. When students take a lunch break, their belongings can be stored in the drawer from the tabletop, making it convenient for students to put their legs on the tabletop and preventing their belongings from falling out.

[0011] The table leg assembly includes an outer tube and an inner tube. The outer tube is fitted onto the inner tube, and the lower end of the outer tube is connected to a floor leg. The upper end of the inner tube is connected to the first tabletop. A telescopic rod is provided between the inner and outer tubes. The telescopic rod can extend and retract to adjust the relative position of the outer and inner tubes, thereby adjusting the height of the table leg assembly and ultimately adjusting the height of the tabletop assembly.

[0012] The outer tube has a first rib on its side wall, and the inner tube has a second rib on its side wall, with the first and second ribs positioned correspondingly. The ribs enhance the structural strength of the outer and inner tubes, preventing bending under pressure and improving the desk's load-bearing capacity. Both the first and second ribs are arc-shaped concave ribs.

[0013] The upper end of the inner tube is connected to a support plate, which is connected to the first tabletop. Hooks are connected to the side of the support plate. The support plate increases the support area of ​​the table leg assembly on the tabletop assembly, thereby ensuring the stability of the table leg assembly in supporting the tabletop assembly. The hooks make it convenient for students to hang their schoolbags.

[0014] The beneficial effects of this utility model are: the height of the tabletop component can be adjusted by raising and lowering the table leg assembly, and the second tabletop can slide back and forth relative to the first tabletop. When students are taking a nap, the tabletop component can be lowered by raising the table leg assembly, and then the relative positions of the first and second tabletops can be adjusted according to the student's height, so that the tabletop can provide full support for the student's legs, avoiding the situation where the student's legs are dangling, enhancing the comfort of the student's legs, and ensuring the effectiveness of the student's nap.

[0015] The table leg assembly adjusts the relative position of the outer and inner tubes by extending and retracting the telescopic rod, thereby raising and lowering the desk. Both the outer and inner tubes are reinforced with ribs, which enhance the structural strength of the outer and inner tubes, prevent the outer or inner tubes from bending under pressure, and improve the desk's load-bearing capacity.
