Description

Technical Field

[0001] This utility model relates to a catering equipment, specifically a self-service dining table with a nested multi-layer turntable structure, belonging to the field of dining table design technology that combines structural optimization and functional improvement. Background Technology

[0002] Self-service tables often employ a rotating structure for easy food retrieval. Current technologies typically use single-layer turntables, which cannot meet the needs of multiple users navigating from multiple directions simultaneously. Some products have attempted multi-layer turntables, but these suffer from structural instability, uncoordinated rotation, and severe interference between layers. Especially in scenarios where multiple turntables rotate simultaneously or are used frequently, misalignment between layers can easily occur, affecting usability and even causing tableware to tip over. Furthermore, traditional structures lack effective shock absorption design, leading to wobbling, noise, or discomfort during rotation.

[0003] Therefore, there is an urgent need to propose a self-service dining table structure that is structurally stable, rotates smoothly, and is easy to use in multi-layer collaborative applications, in order to solve the problems of poor stability and low safety in the existing multi-layer turntable design. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a self-service dining table with a nested multi-layer turntable structure. By incorporating a limiting buckle structure and an elastic shock-absorbing structure, it effectively enhances the stability of the interlayer connections and the overall safety and comfort of use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nested multi-layer turntable structure buffet dining table includes a tabletop, a turntable assembly, and a support structure. The turntable assembly includes at least two layers of turntables, which are stacked sequentially in a nested structure. A limit latch structure is provided between adjacent turntables to limit axial or radial displacement between layers. An elastic shock-absorbing structure is provided between the bottom of each turntable and the support structure to buffer the vibration generated during rotation.

[0007] Furthermore, the limiting buckle structure includes a buckle protrusion on the bottom surface of the upper turntable that engages with a buckle groove on the top surface of the lower turntable. The buckle structure is symmetrically arranged to ensure stable engagement and balanced force distribution.

[0008] Furthermore, the elastic damping structure is a rubber washer, a spring washer, or a silicone buffer, which is disposed at the contact surface between each turntable and the mounting plate, and is evenly spaced.

[0009] Furthermore, the nested structure can be implemented in various ways, including but not limited to: 1. The bottom of the upper turntable has an annular flange, and the top of the lower turntable has a matching annular groove, using a plug-in connection to achieve nesting; 2. By setting inner and outer ring structures, the outer wall of the upper turntable has a lower insert ring, and the inner ring of the lower turntable has a guide groove, using a sliding-in structure for nesting; 3. A semi-circular retaining ring structure is set on the edge of the turntable, and the upper turntable achieves limited nesting by rotating and inserting into the retaining ring track. All of the above methods can effectively form interlayer interlocking positioning, preventing radial or axial displacement.

[0010] Furthermore, the limiting buckle structure can adopt various modified structures, including but not limited to: an interference fit structure with a conical protrusion and a conical groove, a ball-head plug insertion limiting structure, an elastic barbed insert structure, and a sliding limiting structure with a buckle spring, etc. Different materials and fitting precision can be selected according to the application scenario to achieve the technical effect of both limiting function and easy disassembly and maintenance.

[0011] This invention has the following advantages: the nested structure is reasonable, effectively preventing misalignment between layers; the elastic buffer design improves rotational stability and user comfort, making it suitable for various buffet application scenarios.

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example 1: As Figure 1 As shown, this embodiment provides a self-service dining table with a nested multi-layer turntable structure, including a tabletop 1, a turntable assembly 2, and a support structure 3. The turntable assembly 2 includes three layers of circular turntables stacked sequentially from bottom to top. Each turntable has a downward-extending annular flange on its bottom outer edge and an annular groove on the inner edge of the corresponding lower turntable. The two layers are nested together to form a stable connection, while limiting radial displacement and rotational deviation. The nested structure uses a ring-type fit, which has a certain interference fit accuracy to ensure stable interlayer engagement. A limiting buckle structure 4 is provided between each turntable layer to prevent relative displacement during rotation.

[0023] Example 2: The limiting buckle structure 4 includes several inverted conical protrusions 41 on the bottom surface of the upper turntable, which engage with corresponding conical grooves 42 on the top surface of the lower turntable. After the protrusions 41 are inserted into the grooves 42, an interference fit is formed, providing limiting and self-locking functions, effectively restricting axial floating and radial slippage between layers. This structure prevents offset during rotation through conical surface friction, while also facilitating installation and disassembly. Each buckle unit is evenly distributed along the circumference, ensuring balanced limiting at multiple points.

[0024] Example 3: The support structure 3 includes a central load-bearing column 31 and an upper mounting plate 32. The mounting plate supports the bottom turntable and bears the weight of the upper nested layers. The support structure is made of metal, has strong load-bearing capacity, and high stability.

[0025] Example 4: The elastic shock-absorbing structure 5 is located between the mounting plate and the bottom contact surface of each turntable layer, and includes several circular silicone buffer pads evenly distributed along the contact edges of the turntables. This structure is mainly used to absorb the vertical micro-impact forces and slight radial swaying generated during rotation, thereby alleviating vibrations and noise caused by starting, stopping, or inertia, and improving the smoothness of rotation and user comfort. The buffer components are fixed by a slotted installation method to ensure structural stability and facilitate disassembly and replacement.

[0026] In some application scenarios, the elastic damping structure 5 can also be configured in combination. For example, rubber washers and spring washers can be stacked sequentially at the same contact surface, or silicone buffers and rubber washers can be staggered in different contact areas to achieve combined buffering of materials with different elastic moduli. This combined configuration can simultaneously meet the buffering requirements of rapid response and slow pressure release, improving shock resistance and rotational stability, making it suitable for buffet-style scenarios with frequent load changes or high vibration frequencies. The components are fixed together by nesting, adhesive, or fitting to maintain a compact structure.

[0027] Example 5: The tabletop 1 covers the support structure 3, with its outer edge extending beyond the edge of the turntable assembly 2, serving both protective and decorative purposes while preventing food from slipping off the table. The tabletop is made of solid wood with an oil-resistant coating for easy cleaning and maintenance.

[0028] In summary, this utility model, through the combined design of a limiting buckle structure and an elastic shock-absorbing structure, significantly improves the overall stability, safety, and practicality of the nested multi-layer turntable structure buffet table, making it suitable for efficient buffet use in various scenarios.
