Description

Technical Field

[0001] This utility model relates to the field of dining table technology production, and in particular to a lifting and rotating mechanism that facilitates fixing and adjusting the turntable. Background Technology

[0002] A dining table is a table specifically for eating. According to the material, it can be divided into solid wood dining tables, steel and wood dining tables, marble dining tables, sintered stone dining tables, iron plate dining tables, aluminum plate dining tables, acrylic plate dining tables, etc.

[0003] Rotating dining tables (also known as turntable tables) are currently a very common type of furniture in modern Chinese dining culture, especially suitable for family gatherings and entertaining guests. They allow each dish on the table to easily rotate to each guest without having to get up or bother others to pass it around, creating an atmosphere of equality and respect. Condiments, serving chopsticks, napkins, and other frequently used items can also be placed on the turntable for easy access. Currently, rotating dining tables come in two types: separate and integrated. Separate turntables rotate independently on the table's turntable, which can lead to height differences and is not practical. Integrated turntables, on the other hand, have a groove in the center of the table, with the turntable embedded in the groove, so that the upper surface of the turntable is at the same level as the upper surface of the table's turntable, eliminating height differences. However, after prolonged use, the turntable may become uneven, and its level cannot be readjusted. Summary of the Invention

It is set in a groove in the center of the dining table, and the back of the turntable is attached by the suction cup of the locking device. When the height difference needs to be adjusted, the position of the locking nut on the stud can be adjusted. Moreover, when rotation is needed, the turntable can be rotated by the rotating device in the rotating base. If the height needs to be adjusted, the turntable can be raised or lowered by the lifting device on the base.

The upper ring 221 is connected to the fixed plate 21 and is slidably connected to the lower ring 222. The internal gear ring 225 is fixedly connected to the upper ring 221. The rotating motor drives the gear 224 to rotate, which in turn drives the internal gear ring 225 (which has gear teeth) to rotate, thereby driving the upper ring 221 to rotate, which in turn drives the fixed plate 21 to rotate. In addition, there is at least one gear 224, and each gear 224 is connected to a rotating motor. The number of rotating motors is determined by the power.

[0034] In this utility model, the lifting device 11 includes a mounting plate 12, a lifting motor 13, a steering mechanism 14, and a lifting mechanism 15.

Each of the boxes 151 is connected by a rotating rod 152. The two ends of the drive rod 142 are respectively connected to a right-angle gearbox 151 in the first lifting group and the second lifting group. The lifting motor 13 drives the steering gear 141, thereby driving the drive rod 142 to rotate. The two ends of the drive rod 142 drive one right-angle gearbox 151 to work, and then drive the other two right-angle gearboxes to work, so that the mounting plate 12 is lifted and lowered through the lifting screw cylinder 153. The right-angle gearbox 151 can be a 2:1 or 1:1 right-angle steering gearbox. When adjusting the height difference of the turntable or cleaning the groove inside the dining table, the mounting plate 12 can be raised by the lifting device 11, which makes it convenient to clean or sweep the groove of the dining table, and also makes it convenient to adjust the fixed plate 21. Since the fixed plate 21 is also raised, it is convenient to install the turntable 4 and adjust the flatness of the turntable 4.
