Description

Technical Field

[0001] This utility model relates to the field of dining table technology, and in particular to a rotating connection structure for a dining table. Background Technology

[0002] A turntable table is a round table equipped with a rotating turntable in the center. Its main function is to allow the food on the table to be easily rotated to each diner, making it convenient for everyone to share the meal.

[0003] Some turntable tables have LED strips on both the table and the turntable. However, the LED strip on the turntable is connected to the electrical circuit of the table via wires. To prevent the wires from breaking during rotation, the turntable cannot continue to rotate after two rotations. Forcing it to rotate may cause the LED strip on the turntable to malfunction.

[0004] Therefore, a rotating connection structure for the dining table is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that some turntable dining tables have light strips on both the table and the turntable. However, after the light strip on the turntable is connected to the electrical circuit of the table through wires, the turntable cannot continue to rotate after two rotations to avoid the wires breaking. Forcing the turntable to rotate may cause the light strip to fail. This utility model provides a rotating connection structure for the dining table.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A rotating connection structure for a dining table includes a fixed plate and a movable plate. The fixed plate is used to fix the dining table, and the movable plate is used to fix the rotating tabletop. The fixed plate and the movable plate are rotatably connected by bearings. The fixed plate has several annular grooves with gradually decreasing diameters from the outside to the inside. A copper plate is provided on the bottom surface of the annular grooves. The copper plate is connected to a power line through a wire. The movable plate has several through holes on its bottom, and telescopic probes are provided in the through holes.

[0008] As an improvement, the telescopic probe is a spring-driven contact needle that contacts and is electrically connected to a copper plate. The telescopic probe is connected to a connecting wire that extends to the moving plate.

[0009] As an improvement, the width of the annular groove is greater than the outer diameter of the telescopic probe.

[0010] As an improvement, the outer diameter of the moving disk is larger than the outer diameter of the outermost annular groove.

[0011] The beneficial effects of this utility model are as follows:

[0012] To ensure stable power transmission to the rotating dining table, a non-fixed electrical contact method is used between the telescopic probes and copper plates on the table and the rotating tabletop, allowing the rotating tabletop with LED strips to maintain continuous rotation in the same direction.

[0021] Reference Figure 1-3 A rotating connection structure for a dining table includes a fixed plate 1 and a movable plate 2. The fixed plate 1 is used to fix the dining table, and the movable plate 2 is used to fix the rotating tabletop. The fixed plate 1 and the movable plate 2 are rotatably connected by bearings. The fixed plate 1 has several annular grooves 3 with gradually decreasing diameters from the outside to the inside. The bottom surface of the annular grooves 3 is provided with a copper plate 4. The copper plate 4 is connected to a power line 5 through a wire. The movable plate 2 has several through holes 6 on its bottom. Telescopic probes 7 are provided in the through holes 6.

[0022] The telescopic probe 7 is a spring-driven contact needle. The needle contacts and is electrically connected to the copper plate 4. The telescopic probe 7 is connected to a connecting wire 8, which extends to the moving plate 2. Through the contact design between the telescopic probe 7 and the copper plate 4, seamless power transmission between the moving plate 2 and the fixed plate 1 is achieved, and a stable electrical connection can be maintained even if the tabletop continues to rotate.

[0023] The width of the annular groove 3 is greater than the outer diameter of the telescopic probe 7. This setting ensures that the probe can slide freely in the groove (reducing rotational resistance) and avoids direct metal-to-metal contact wear through appropriate gaps, thus extending service life.

[0024] The outer diameter of the moving disk 2 is larger than the outer diameter of the outermost annular groove 3.

[0025] In a specific implementation case, the circuit connected to the light strip on the dining table is electrically connected to the connecting wire 8, and the control circuit of the light strip on the rotating table is electrically connected to the copper plate 4. During the continuous rotation of the table, the telescopic probe 7 is always in contact with the copper plate 4 and maintains electrical connection. When one side of the rotating table tilts due to food, the rotating probe retracts or extends, and the telescopic probe 7 always remains in contact with the copper plate 4 to prevent the circuit from being disconnected.
