Description

Technical Field

[0001] This utility model relates to the field of dining table technology, and in particular to an improved expandable dining table. Background Technology

[0002] Expandable round dining tables are commonly used in daily life, but most have small tabletops with limited diameter changes, failing to achieve a significant difference between the retracted and expanded diameters. Chinese utility model patent CN202120007425.0 discloses an expandable dining table comprising a main body, a telescopic mechanism, a central bearing, a lifting mechanism, an expansion mechanism, and a top bearing. The table has a diameter of 1.35 meters when retracted and 1.9 meters when expanded, exhibiting a large diameter change. It saves space when retracted and has a thin tabletop. However, this table has a significant gap between the retracted and expanded tabletops, the table ring adjustment is inconvenient, and the metal structural components have slightly insufficient strength. Utility Model Content

[0003] In view of this, an improved expandable dining table with high structural strength, small tabletop spacing and easy adjustment is provided.

[0004] An improved expandable dining table includes a main body 20, a telescopic mechanism 30, a central bearing 40, a lifting mechanism 50, an extension mechanism 60, and a rotating mechanism 70. The main body 20 includes table legs 21, a base plate 22, a ramp 23, a bottom bearing 24, a sliding block 25, a table ring 26, and a small tabletop 27. The table legs support and connect to the base plate 22. The bottom bearing 24 is installed on the base plate 22, and the sliding block 25 is installed on the edge of the base plate 22. The telescopic mechanism 30 includes an upper telescopic plate 31 and a lower telescopic plate 32. The lifting mechanism 50 includes a lifting pin 51 and a lifting plate 52.

The extension mechanism 60 includes a five-sided disc 61, a second sliding block 62, a pin sleeve 63, a suspension plate 64, and a trapezoidal fastener 65. The five-sided disc 61 is connected to the bottom bearing 24. The pin sleeve 63 is located on the surface of the five-sided disc 61. The suspension plate 64 is located above the five-sided disc 61. The trapezoidal fastener 65 is installed on the surface of the table base plate 22 and located on both sides of the second sliding block 62. The rotation mechanism 70 includes an inner rotating core 71, an outer rotating core 72, and a constant speed motor 73. The inner rotating core 71 and the outer rotating core 72 are coaxially and movably connected. The constant speed motor 73 is meshed with the inner rotating core 71.

[0005] Furthermore, the inclined block 23 includes an inclined block body 231, a load-bearing bearing 232, a nut 233, and an adjusting bolt 234. The adjusting bolt 234 penetrates the table base plate 22 and is vertically downward, making it easy to adjust the height of the table ring 26 by adjusting the adjusting bolt 234.

[0006] Furthermore, the sliding block 25 includes a sliding block body 251 and a slide rail 252. The sliding block body 251 is mounted on the slide rail 252. There are 10 sets of sliding blocks 25. The 10 sets of sliding blocks 25 are mounted on 5 sets of upper telescopic plates 31 and 5 sets of lower telescopic plates 32, which are movably connected by a crank rod 62.

[0007] Furthermore, the inner wall of the table ring 26 is provided with a sloping groove 261, and the load-bearing bearing (232) is connected to the sloping groove 261.

[0008] Furthermore, the intermediate bearing 40 is mounted on the surface of the five-sided disc 61.

[0009] Furthermore, the top block bearing 53 is fixedly connected to the handle 54, and the magnetic block 55 is installed at the bottom of the table base plate 22.

[0026] Please see Figures 1 to 9 This illustration shows an embodiment of the present invention: an improved expandable dining table, comprising a dining table body 20, a telescopic mechanism 30, a central bearing 40, a lifting mechanism 50, an extension mechanism 60, and a rotating mechanism 70. The dining table body 20 includes table legs 21, a table base plate 22, a wedge 23, a bottom bearing 24, a sliding block 25, a table ring 26, and a small tabletop 27. The table legs support and connect to the table base plate 22. The bottom bearing 24 is installed on the table base plate 22, and the sliding block 25 is installed on the surface edge of the table base plate 22. The telescopic mechanism 30 includes an upper telescopic plate 31 and a lower telescopic plate 32. The lifting mechanism 50 includes a lifting pin. 51. Lifting plate 52. Top block bearing 53. Handle 54. Magnet 55. The extension mechanism 60 includes a five-sided plate 61, a second sliding block 62, a pin sleeve 63, a suspension plate 64, and a trapezoidal fastener 65. The five-sided plate 61 is connected to the bottom bearing 24. The pin sleeve 63 is located on the surface of the five-sided plate 61. The suspension plate 64 is located above the five-sided plate 61. The trapezoidal fastener 65 is installed on the surface of the table base plate 22 and located on both sides of the second sliding block 62. The rotating mechanism 70 includes an inner rotating core 71, an outer rotating core 72, and a constant speed motor 73. The inner rotating core 71 and the outer rotating core 72 are coaxially and movably connected. The constant speed motor 73 is meshed with the inner rotating core 71.

[0027] Furthermore, as a preferred embodiment, the inclined block 23 includes an inclined block body 231, a load-bearing bearing 232, a nut 233, and an adjusting bolt 234. The adjusting bolt 234 penetrates the table base plate 22 and is vertically downward, which facilitates adjusting the height of the table ring 26 by adjusting the adjusting bolt 234. It is inconvenient to use an open wrench to adjust the adjusting bolt 234 from the top, so it is now changed to be adjusted from under the table, mainly to adjust the production tolerance of the contact between the table ring 26 and the table base plate 22.

[0028] Furthermore, as a preferred embodiment, the sliding block 25 includes a sliding block body 251 and a slide rail 252. The sliding block body 251 is mounted on the slide rail 252. There are 10 sets of sliding blocks 25. The 10 sets of sliding blocks 25 are mounted on 5 sets of upper telescopic plates 31 and 5 sets of lower telescopic plates 32, which are movably connected by a crank rod 62.

[0029] Furthermore, as a preferred embodiment, the inner wall of the table ring 26 is provided with a groove 261, and the load-bearing bearing (232) is connected to the groove 261.

[0030] Furthermore, as a preferred embodiment, there are two sets of uniform speed motors 73, and the two sets of speed motors 73 are arranged symmetrically.

[0031] Furthermore, as a preferred embodiment, the intermediate bearing 40 is mounted on the surface of the five-sided disc 61.

[0032] Furthermore, as a preferred embodiment, the top block bearing 53 is fixedly connected to the handle 54, and the magnet 55 is installed at the bottom of the table base plate 22.

[0033] Furthermore, as a preferred embodiment, the bottom of the upper telescopic plate 31 is provided with a tapered plate 311, a rolling bearing 312 and a sliding bushing 313. When the dining table is unfolded, the rolling bearing 312 raises the upper telescopic plate 31 to the same height as the lower telescopic plate 32 through the trapezoidal fastener 65. This design greatly reduces the gap between the small table 27 and the upper telescopic plate 31 and the lower telescopic plate 32.

[0034] The working principle of the improved expandable dining table described above is as follows: When the dining table is folded up, first rotate the table ring 26 to lower it, then rotate the small tabletop 27. The small tabletop 27 drives the five-sided plate 61 to rotate via the lifting pin 51 on the lifting plate 52. The five-sided plate 61 pushes out the upper telescopic plate 31 and the lower telescopic plate 32 via the crank rod 62. When the upper telescopic plate 31 and the lower telescopic plate 32 are pushed to their limit, rotate the handle 54 to lower the lifting plate 52 via the top bearing 53. The lifting pin 51 on the lifting plate 52 separates from the small tabletop 27, allowing the small tabletop 27 to rotate freely without driving the upper telescopic plate 31 and the lower telescopic plate 32. The dining table is now fully expanded. To fold it up, simply reverse the operation. During meals, the constant speed motor 73 drives the inner rotating core 71 to rotate, which in turn drives the small tabletop 27 to rotate at a constant speed.

[0035] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
