Description

Technical Field

[0001] This utility model belongs to the field of educational equipment technology and relates to a school desk. Background Technology

[0002] Traditionally, students rest by lying face down on their desks during lunch breaks at school. This affects the quality of their rest, and prolonged face-down rest is also detrimental to students' cervical spine health. Therefore, desks and chairs designed for lunch breaks have become a trend in the development of teaching equipment. However, due to space limitations in classrooms, the space between desks and chairs in the front and back rows is generally very small, making it difficult to accommodate the space needed to adjust the chair back to a reclining position. Therefore, side-reclining lunch break desks, which make efficient use of the space under the desk, have become a hot research topic in lunch break desk development.

[0003] For example, Chinese patent application (application number: 202322759382.3) discloses a desk, including a tabletop, cantilever beams, a left table leg, and a right table leg. There are two cantilever beams distributed front and back, and both cantilever beams are arranged horizontally. The tabletop is laid on the two cantilever beams. The left ends of the two cantilever beams are connected to the left table leg by vertically arranged table legs. The right ends of the two cantilever beams are suspended. The right table leg is located below the right ends of the two cantilever beams. The left and right table legs are both long strips and are arranged in the front and back direction. The desk also includes a support rod, which is parallel to the cantilever beams. The left end of the support rod is fixed to the table leg and is higher than the left table leg, and the right end is fixed to the right table leg.

[0004] The aforementioned desks utilize the space beneath them effectively by using a single-sided leg for support, allowing students to lie down and nap during lunch breaks. However, due to the limited support strength of a single leg on the tabletop, two cantilever beams need to be added to the single-sided leg to support the tabletop and book drawer. While this design ensures the necessary support strength for the tabletop and book drawer, the two cantilever beams also encroach on the legroom under the book drawer, restricting students' leg movement. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a new type of desk. The technical problem this utility model aims to solve is the limited space for movement under existing single-sided desks.

[0006] The purpose of this utility model can be achieved through the following technical solution: a desk, including a tabletop, a book drawer and two support legs, wherein the two support legs are arranged at intervals along one side of the tabletop, and the other side of the tabletop is suspended. The desk is characterized in that the tops of the two support legs are connected by support rods, and an L-shaped support beam is connected to the support leg located on the front side, and a reinforcing rod is connected between the support beam and the support leg. The support beam and the support rod form a U-shaped structure, the tabletop is fixed against the support beam and the support rod, and the book drawer is embedded between the support beam and the support rod.

[0007] This desk features an improved design with support rods and L-shaped support beams on the legs, forming a U-shape. The reinforcing rods, support legs, and L-shaped support beams create a triangular reinforcement structure, ensuring the support strength of the beams. Simultaneously, the support rods and L-shaped support beams encircle the bottom of the desk, providing stable support at 270 degrees circumferentially with higher strength. The drawers are embedded between the support rods and beams. Therefore, while ensuring sufficient support strength for the desk and adequate storage space for books, it also frees up the space previously occupied by cantilever beams, increasing legroom for students.

[0008] In the aforementioned desk, the bending points of the support beam are rounded and integrally formed. This rounded, integral forming of the support beam provides better overall strength compared to welding, and the rounded transition is also safer.

[0009] In the aforementioned desk, both the support beams and support rods are square tubular in shape, with their top surfaces flush. The square tubular shape of the support beams and support rods provides stable support for the desk surface and facilitates the connection and fixation of the desk surface to the support beams and support rods.

[0010] In the aforementioned desk, both support legs are height-adjustable. Mounting holes are located on the side walls of both legs near the top. A detachable blocking plate covers the mounting holes on the front support leg. The height adjustment mechanism is a conventional hand-cranked system, with both hand-cranked mechanisms synchronously controlled by hexagonal screws. The mounting holes facilitate the installation of these hexagonal screws. This structural design allows both support legs to be identical, achieving versatility.

[0011] In the aforementioned desk, the book drawer has a folded edge, which is clamped between the tabletop, support rod, and support beam. The support rod is fixed to the tabletop and the folded edge, as are the support beam and the tabletop and the folded edge, using fasteners. This configuration ensures stable support for both the tabletop and the book drawer from the support beam and support rod.

[0012] In the aforementioned desk, the book drawer has a recessed area, and the support rod is embedded within this recessed area. This design allows the entire book drawer to fully utilize the space along the left and right widths of the support legs, resulting in a larger storage space and better meeting the students' storage needs.

[0013] Compared with existing technologies, this desk has the following advantages: The structure of supporting rods and L-shaped supporting beams on the supporting legs can support the bottom of the desk and the book drawer around the outer perimeter of the desk, forming a stable support along the circumference of 270 degrees, and the support strength is higher. The book drawer is embedded between the supporting rods and supporting beams. Therefore, while ensuring sufficient support strength for the desk and normal storage space for the book drawer, it can free up the space that would have been used to install a cantilever beam under the desk, increasing the legroom for students.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] Example 1

[0022] like Figure 1As shown, this desk includes a tabletop 1, a book drawer 2, two support legs 3, a base 10, and a support crossbar 9. The two support legs 3 are arranged at intervals along one side of the tabletop 1, and the other side of the tabletop 1 is suspended. The base 10 is located below the suspended side of the tabletop 1. The support crossbar 9 is L-shaped, with one end connected to the base 10 and the other end connected to the support leg 3 located on the front side.

[0023] like Figure 2 and 3 As shown, the tops of the two support legs 3 are connected by support rods 4. An L-shaped support beam 5 is also connected to the front support leg 3, and a reinforcing rod 6 connects the support beam 5 to the support leg 3, forming a triangular support. Both the support beam 5 and the support rod 4 are square tubular, and their top surfaces are flush. The bends of the support beam 5 are rounded and integrally formed, creating a U-shaped structure with the support beam 5 and support rod 4.

[0024] like Figure 1 and 4 As shown, the tabletop 1 is fixed against the support beam 5 and the support rod 4, and the book drawer 2 is embedded between the support beam 5 and the support rod 4. The book drawer 2 has a flange 2a, which is clamped between the tabletop 1, the support rod 4, and the support beam 5. The support rod 4 is fixed to the tabletop 1 and the flange 2a, and the support beam 5 is fixed to the tabletop 1 and the flange 2a by fasteners. The book drawer 2 has a recess 2b, and the support rod 4 is embedded in the recess 2b. This design allows the book drawer 2 to make full use of the space along the left and right width of the support legs 3, resulting in a larger storage space and better meeting the storage needs of students.

[0025] Furthermore, both support legs 3 are capable of rising and falling. Each support leg 3 includes an upper support leg 3a and a lower support leg 3b. The upper support leg 3a passes through the lower support leg 3b and can rise and fall relative to the lower support leg 3b. Mounting holes 3c are provided on the side walls of both upper support legs 3a near the top. A crossbar 8 connects the two lower support legs 3b. Each support leg 3 is equipped with a hand-cranked lifting mechanism. The two hand-cranked lifting mechanisms are connected and synchronously controlled by a hexagonal screw. The hexagonal screw passes through the support rod 4, and its two ends extend from the mounting holes 3c into the two upper support legs 3a and are connected to the two hand-cranked lifting mechanisms. The specific hand-cranked lifting mechanism is an existing structure, such as that in application number 202120937866.0, which will not be described in detail here. The mounting holes facilitate the installation of the hexagonal screw, allowing the two support feet 3 to have the same structure and achieve versatility. After installation, one end of the hexagonal screw passes through the mounting hole 3c of the rear support foot 3 for connection with the hand crank. A blocking plate 7 that can cover the mounting hole 3c on the upper support foot 3 is detachably connected to the front upper support foot 3a.

[0026] This desk features a structure with support rods 4 and L-shaped support beams 5 on the support legs. These support rods surround the outer perimeter of the desk 1 and support the bottom of the desk 1 and the book drawer 2, providing stable support at 270 degrees circumferentially. The support strength is also higher. The book drawer can be embedded between the support beams 5 and the support rods 4. Therefore, while ensuring sufficient support strength for the desk 1 and normal storage space for the book drawer 2, it also frees up the space that would have been used to install a cantilever beam under the desk, increasing the legroom for students.
