Description

Technical Field

[0001] This utility model relates to the field of turntable mechanism technology, and more specifically, to an electric dining table mechanism that can adapt to tabletops of various sizes. Background Technology

[0002] Currently, dining tables used in homes and restaurants generally fall into two categories: standard dining tables and turntable tables. Standard dining tables cannot rotate, which is inconvenient when there are many diners and the table is large, as diners need to exchange and pass plates between each other. Turntable tables, on the other hand, are manually rotated, and often due to rusted axles or other reasons, excessive force can cause food and soup to splash out of the plates on the turntable. In some cases, the turntable itself can even be pushed off the table.

[0003] To address the aforementioned issues, patent document publication number CN220327047U discloses an electric turntable mechanism for a dining table, comprising a support column, an upper support arm, a gear transmission assembly, and a drive device. The bottom of the upper support arm is connected to the top of the gear transmission assembly, the gear transmission assembly is sleeved on the top of the support column, and the drive device is connected to the gear transmission assembly to drive the gear transmission assembly to rotate around the support column. The drive device is located on one side of the support column.

[0004] However, it still has some drawbacks in actual use. For example, the above device uses the support column as the main shaft and installs the upper support arm on both sides of it. The dining table is placed on the upper support arm, and the upper support arm rotates smoothly through the gear transmission assembly and drive device, thereby realizing the rotation of the dining table. However, since the upper support arm is a fixed structure with one piece, it cannot be adjusted according to the table specifications, which reduces the practicality of the dining table mechanism to a certain extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide an electric dining table mechanism that can adapt to tabletops of multiple specifications, so as to solve the problem that the support arm cannot be adjusted according to the specifications of the tabletop in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electric dining table mechanism adaptable to multiple tabletop sizes, including a supporting column, the electric dining table mechanism adaptable to multiple tabletop sizes further including...

[0007] An upper support arm is fixedly installed on the surface of a support column, and a stabilizing frame is provided on the surface of the upper support arm.

[0008] An extension column, which is slidably mounted on the top of the upper support arm;

[0009] A connecting seat is fixedly installed on one side of the extension column along its length, and a mounting hole is provided through the interior of the connecting seat;

[0010] A fixing groove is provided at equal intervals on the bottom surface of the extension column;

[0011] An anti-slip mat is provided on the top surface of the extension column.

[0012] The device includes a fixed base, a spring, a connecting plate, an L-shaped frame, a snap-fit ​​block, and an expansion block. The fixed base is positioned opposite each other on both sides of the upper support arm in the width direction. The fixed base has a hollow structure. One end of the spring is fixedly connected to the bottom of the inner cavity of the fixed base, and the other end of the spring is fixedly connected to the bottom surface of the connecting plate. The side of the connecting plate is in contact with the inner wall of the fixed base. One side of the top of the L-shaped frame is fixedly connected to the surface of the connecting plate. The surface of the L-shaped frame is slidably connected to the bottom of the fixed base. The bottom of the L-shaped frame is fixedly connected to the side of the snap-fit ​​block. The top of the snap-fit ​​block is snapped into the inside of the fixed groove. The expansion blocks are positioned opposite each other on both sides of the bottom of the snap-fit ​​block.

[0013] The bottom of the connector is provided with a fitting pad, the surface of which is fixedly connected to a connecting end, and the top of which is provided with a brake ring, the top surface of which is in contact with the bottom surface of the connector.

[0014] The inner wall of the connecting end is rotatably mounted with a rotating column. The top of the rotating column is rotatably connected to the inner wall of the top of the connecting seat. The outer wall of the bottom of the rotating column is in contact with the inner ring of the brake ring. A second connecting plate is provided on the surface of the rotating column. An installation ring is provided on the side of the second connecting plate opposite to the rotating column.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] In the above scheme, before the tabletop is connected to the top of the upper support arm, the locking block is moved downward by holding the extension block. At this time, the connecting plate in the fixed seat moves synchronously to compress the spring. After the locking block moves downward, its top engages with the fixing groove opened on the bottom surface of the extension column. Then, the extension column can be moved horizontally according to the tabletop specifications, so that the connecting seat moves to a suitable position at the bottom of the tabletop, ensuring that the upper support arm and the extended column can stably support the tabletop as a whole. Then, the elastic structure of the spring in the fixed seat drives the connecting plate to move upward and reset, so that the locking block moves synchronously, so that the locking block can engage with the fixing groove at the corresponding position at the bottom of the extension column, thereby fixing the extension column. Then, bolts are installed in the mounting holes to connect and fix the connecting seat to the bottom surface of the tabletop. Through the adjustable structure of the upper support arm, it can be adjusted according to the tabletop specifications to ensure stable support for tabletops of different specifications, improving the practicality of the device.

[0017] After the connecting seat is connected to the tabletop using fastening bolts, the bolt ends are tightly pressed against the contact pads at the bottom of the connecting seat. The friction generated by this tight contact can provide a certain braking effect on the bolts, thereby preventing them from loosening during long-term use of the dining table and affecting the stability of the tabletop. In addition, by rotating the mounting ring and connecting plate horizontally around the rotating column, the mounting ring can move to both sides of the connecting seat, and the bolts can be passed through the mounting rings to connect with the bottom of the tabletop, further fixing the tabletop and the upper support arm and ensuring the stability of the connection between the two.

An installation ring 20 is provided on the side of the connecting plate 29 opposite to the rotating column 18.

[0034] The working process of this utility model is as follows: Before the tabletop is connected to the top of the upper support arm 2, the locking block 13 is moved downward by holding the extension block 14. At this time, the connecting plate 11 set in the fixed seat 9 moves synchronously to compress the spring 10. After the locking block 13 moves downward, its top is connected to the fixing groove 7 opened on the bottom surface of the extension column 4. Then the extension column 4 can be moved horizontally according to the tabletop specifications, so that the connecting seat 5 moves to a suitable position at the bottom of the tabletop, ensuring that the upper support arm 2 and the extended extension column 4 can stably support the tabletop as a whole. Then, the elastic structure of the spring 10 set in the fixed seat 9 drives the connecting plate 11 to move upward and reset, so that the locking block 13 moves synchronously, so that the locking block 13 can engage with the fixing groove 7 at the corresponding position at the bottom of the extension column 4, thereby fixing the extension column 4. Then, the connecting seat 5 is connected and fixed to the bottom surface of the tabletop by installing bolts in the mounting hole 6.
