Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a combined dining table. Background Art

[0002] A dining table is one of the essential furniture for a family. A general dining table is simply a combination of a tabletop and table legs, and the tabletop is mostly fixed. When there are many guests at home, the tabletop is too small to meet the needs of multiple people dining at the same time. In order to solve this problem, some modular dining tables have appeared on the market, that is, a larger tabletop is directly laid on a smaller tabletop. However, this structure has poor stability and is likely to cause the laid tabletop to fall off the table legs due to local stress on the surrounding area. Utility Model Content

[0019] The following detailed description provides various embodiments or examples for implementing the present invention. These are, of course, merely examples and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. This repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the various embodiments and / or configurations discussed.

[0020] like Figure 1-Figure 5The combined dining table shown includes a square table top 1 and a supporting leg 2 provided at the lower end of the square table top 1, and also includes a second table top 3 that can be detachably mounted on the square table top 1. Four supporting guide seats 4 are evenly distributed in an array along the circumference on the lower end surface of the second table top 3, and a sliding plate 5 slides on each of the supporting guide seats 4. Each of the sliding plates 5 slides along the radial direction of the second table top 3, and a V-shaped card plate 6 is provided on the lower side of the outer end of the sliding plate 5. A supporting shell 7 that can be supported and placed on the square table top 1 is provided at the center of the lower end surface of the second table top 3, and a linkage drive device is provided on the support shell 7. The linkage drive device can drive the four sliding plates 5 to slide inward at the same time, so that the V-shaped card plate 6 at the outer end of the sliding plate 5 is clamped on the corner of the square table top 1.

[0021] When the second table top 3 needs to be used in combination, the supporting shell 7 of the second table top 3 is directly placed on the square table top 1, and then the four V-shaped clamping plates 6 are aligned with the four corners of the square table top 1. Then, the four sliding plates 5 are driven to slide inward at the same time through the linkage driving device, so that the V-shaped clamping plates 6 at the outer ends of the sliding plates 5 are clamped on the corners of the square table top 1, thereby realizing the fixed connection between the second table top 3 and the square table top 1, which is extremely convenient to assemble and disassemble and has good stability.

[0022] See also Figure 1 、 Figure 4 As shown, the linkage drive device includes a central rotating shaft 21 rotatably arranged in the supporting shell 7, a rotating disk 22 is provided on the central rotating shaft 21, and a connecting rod 23 is hinged at the inner end of each sliding plate 5, and one end of the connecting rod 23 is hinged on the rotating disk 22. Through the rotation of the rotating disk 22, the connecting rod 23 is driven to push or pull the sliding plate 5 to slide, thereby being able to simultaneously drive the four sliding plates 5 to slide outward or inward, thereby improving the efficiency when the second desktop 3 is connected and fixed.

[0023] Furthermore, a gear 31 is coaxially arranged on the central rotating shaft 21, a pull rod 32 is movably arranged on one side of the support shell 7, a rack 33 that can engage with the gear 31 is arranged at one end of the pull rod 32 located inside the support shell 7, and a pull plate 34 is arranged at the outer end of the pull rod 32.

[0024] Furthermore, a sliding seat 41 is provided at the lower end of the second table top 3, and the pull plate 34 is slidably provided in the sliding seat 41. A pin 42 is movably provided on one side of the sliding seat 41, and a socket 43 for inserting the pin 42 is provided at intervals on one side of the pull plate 34.

[0025] During operation, by pulling or pushing the pull plate 34, the rack 33 is engaged with the gear 31 through the pull rod 32, thereby driving the central shaft 21 and the rotating disk 22 to rotate, so that the sliding plate 5 slides, and the V-shaped card plate 6 is clamped on the corner of the square table top 1. At this time, the pin 42 is inserted into the corresponding socket 43 to fix the pull plate 34, so that the V-shaped card plate 6 is stably clamped on the corner of the square table top 1.

[0026] See also Figure 5 As shown, a limiting plate 51 is provided at the lower end of the V-shaped clamping plate 6 , and the limiting plate 51 abuts against the lower end surface of the table corner, further improving the stability when combined with the square table top 1 .

[0027] In order to facilitate the insertion of the corners of the table top 1 into the V-shaped clamping plate 6 , a guiding slope 61 is provided at the outer corner of the limiting plate 51 .

[0028] In order to prevent the table top 1 from being scratched by the support shell 7 , a soft rubber pad is provided on the lower end surface of the support shell 7 .
