[0001] This application relates to the field of furniture structure technology, specifically a quick-assembly structure of a support frame and crossbeam and its application in a height-adjustable table. Background Technology

[0002] In modern office equipment, height-adjustable desks are widely used due to their advantages such as adjustable height and flexible use. A height-adjustable desk typically consists of a support frame and a crossbeam to achieve stable support for the overall structure. In existing technology, the connection between the support frame and the crossbeam is mostly secured with fasteners such as screws and bolts. Installation requires tools for alignment, drilling, and tightening, a cumbersome and time-consuming process that is not conducive to quick disassembly and reassembly.

[0003] Furthermore, traditional connection methods suffer from high positioning accuracy requirements, low assembly efficiency, and high labor intensity. In practical use, especially in situations involving large-scale assembly in office settings or frequent handling and disassembly, existing structures struggle to meet the demands for convenient and efficient assembly, thus limiting the wider adoption and use of height-adjustable desks.

[0004] Therefore, there is an urgent need to provide a quick-assembly structure for the support frame and crossbeam that is simple in structure, easy to assemble, and reliably connected, in order to overcome the above-mentioned shortcomings in the existing technology. Utility Model Content

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 4 As shown, this embodiment provides a quick-assembly structure for a support frame and crossbeams, including a support frame 10, a connecting assembly 20, and two crossbeams 30. The support frame 10 and the two crossbeams 30 cooperate to form a support structure for supporting an upper component (such as a desktop).

[0030] The support frame 10 includes a first plate 11 and a second plate 12. The second plate 12 is integrally formed with the first plate 11 and preferably forms an angle with each other (e.g., approximately perpendicular) to improve the strength and stability of the support structure and facilitate the installation of the connecting components 20. The overall cross-section of the support frame 10 can be L-shaped.

[0031] The first plate 11 is a horizontal plate used to connect and cooperate with the two crossbeams 30. When the support frame 10 is connected to the two crossbeams 30, the first plate 11 is placed on the upper surface of the two crossbeams 30 and supported by the two crossbeams 30 from below, thereby forming a support capacity for the upper desktop and other components.

[0032] The connecting assembly 20 is fixedly mounted on the support frame 10, preferably on the second plate 12. The connecting assembly 20 includes a mounting plate 21, two fasteners 22, and an elastic element 23. The mounting plate 21 is provided with a sliding groove 211, and the two fasteners 22 are slidably disposed in the sliding groove 211 so that the two fasteners 22 can reciprocate in the horizontal direction.

[0033] Mounting plate 21 is mounted on second plate 12 by threaded fasteners. Specifically, mounting plate 21 is provided with two threaded holes 212, and second plate 12 is provided with two countersunk holes 121. Two threaded fasteners pass through the two countersunk holes 121 and are screwed into the two threaded holes 212 respectively, so that mounting plate 21 and second plate 12 are reliably connected.

[0034] Each fastener 22 has a first mating part, namely a fastening tooth 221, and the crossbeam 30 has a second mating part, namely a fastening hole 31, that mates with it. The fastening tooth 221 includes an inclined first edge 2211 and a second edge 2212 as a limiting structure, wherein:

[0035] The first edge 2211 has an inclined structure. When the connecting assembly 20 is pressed down with the support frame 10, the first edge 2211 contacts the side wall of the crossbeam 30 and guides the buckle 22 to retract into the mounting plate 21, compressing the elastic element 23. The connecting assembly 20 can move between the two crossbeams 30. When the connecting assembly 20 moves to the position aligned with the buckle hole 31, the elastic element 23 releases its elastic force to push the two buckle 22 out, so that the buckle teeth 221 are respectively engaged in the buckle hole 31.

[0036] Then the second edge 2212 fits against the upper wall of the buckle hole 31, restricting the upward movement of the buckle 22 and ensuring a firm and reliable connection; the second edge 2212 may be provided with a slight inclination relative to the upper wall of the buckle hole 31 to achieve a better fit and locking effect.

[0037] like Figure 3As shown, the mounting plate 21 has two first limiting slots 213, which are used to cooperate with the first limiting part 223 on the fastener 22 to limit the maximum sliding stroke of the fastener 22 in the slide groove 211 and prevent excessive movement that could lead to dislocation. The first limiting part 223 can preferably be located at the bottom of the fastener 22.

[0038] like Figure 2 As shown, the elastic element 23 is preferably a spring, which is located between the two snap fasteners 22. The two ends of the spring are respectively sleeved on the joint portion 222 of the two snap fasteners 22 to provide elastic thrust, push the two snap fasteners 22 to move to the preset snap position and maintain the position.

[0039] Alternatively, the elastic element 23 can also be made of elastic rubber, corrugated leaf spring, shape memory alloy wire, or other components with resilience to meet the needs of different applications.

[0040] Furthermore, the support frame 10 may also be provided with two second limiting slots 111, which are used to cooperate with the second limiting part 224 on the fastener 22 to further restrict the degree of freedom of movement of the fastener 22 in the slide groove and enhance the stability of the overall structure. The second limiting part 224 may preferably be provided on the top of the fastener 22.

[0041] In addition to slotted holes, the limiting structure can also use limiting posts, positioning blocks, flanges, and other components to control the sliding distance and anti-detachment function of the buckle 22.

[0042] The snap holes 31 on the crossbeam 30 can be oblong, square, or other mating structures, and are provided on the side wall of the crossbeam 30 to facilitate the insertion of the snap-fit ​​component from one side. Snap holes 31 are respectively provided on the opposite side walls of the two crossbeams 30. The connecting assembly 20 is located between the two crossbeams 30, and its two snap-fit ​​components 22 extend in opposite directions to snap into the two snap holes 31 respectively.

[0043] The fastener 22 can be an integral structure, or a double-arm, rotating, or insert-type structure. The specific form can be optimized according to the structural space and process requirements.

[0044] like Figure 5 As shown, this utility model also provides a height-adjustable desk, including two crossbeams 30, two support frames 10, and two connecting components 20. One support frame 10 is located at one end of the two crossbeams 30, and the other support frame 10 is located at the other end of the two crossbeams 30. Each support frame 10 is equipped with a connecting component 20 between itself and the two crossbeams 30. This quick-assembly structure allows for rapid assembly with the crossbeams 30, forming a stable desktop support structure that supports the upper desktop panel. The height-adjustable desk has a simple structure, is easy to install and disassemble, and is suitable for office desks, conference tables, and other similar applications. It is particularly suitable for on-site assembly and mobile use.

[0045] In addition, this quick-assembly structure can also be applied to structural systems that require rapid assembly, such as shelves, display racks, and equipment support platforms, and has good modularity, versatility, and ease of installation.

[0046] This specification and accompanying drawings are merely illustrative examples of this application and are intended to cover any and all modifications, variations, combinations, or equivalents within the scope of this application. Clearly, those skilled in the art can make various alterations and modifications to this application without departing from its scope. Therefore, if such modifications and modifications fall within the scope of this application and its equivalents, this application intends to include such modifications and modifications.
