[0002] Existing seats and dining tables are designed to have a rotating function to meet the current increasing usage requirements. In the current rotating structure, a rotating shaft is usually used to support the turntable to achieve the rotating function, and then the turntable is used to support the seat or the tabletop. The disadvantage of this structure is that the rotating shaft bears a large gravity and is prone to deformation after long-term use, resulting in problems such as shaft jamming and unsmooth rotation, which require frequent maintenance and replacement, leading to increased costs. Utility Model Content

The chassis and the rotating disk are rotationally matched through a plurality of first balls. A limiting component for limiting the chassis and the rotating disk is connected to the end of the connecting shaft. A convex platform is formed on the surface of the chassis or the rotating disk away from the limiting component, and a flat abutting member is abutted between the convex platform and the end of the connecting shaft.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0018] Embodiment

[0019] To solve the above technical problems, the present embodiment provides a rotating disk, as Figure 1-2As shown in the figure, it includes a chassis 10, a rotating disk 20 disposed above the chassis 10, and a connecting shaft 30 passing through the chassis 10 and the rotating disk 20. The chassis 10 and the rotating disk 20 are rotationally matched through a plurality of first balls 50, enabling the chassis 10 and the rotating disk 20 to rotate relative to each other. A limiting component 40 for limiting the chassis 10 and the rotating disk 20 is connected to the end of the connecting shaft 30. The chassis 10 and the rotating disk 20 are axially limited by the limiting component 40. A boss 11 is formed on the surface of the chassis 10 or the rotating disk 20 away from the limiting component 40. A flat abutting member 60 is abutted between the boss 11 and the connecting shaft 30. By abutting the abutting member 60 against the boss 11, a gap is formed between the abutting member 60 and the surface of the chassis 10 or the rotating disk 20. Then, one end of the connecting shaft 30 is pressed against the abutting member 60, so that the chassis 10 and the rotating disk 20 can always contact the first balls 50 and achieve rolling cooperation, thereby improving the load-bearing capacity of the entire structure, preventing problems such as unsmooth rotation and frequent replacement, and extending the service life of the rotating disk.

[0020] Specifically, the abutting member 60 is a non-elastic member. As a preferred embodiment, the abutting member 60 is a flat gasket. The surface of the flat gasket abuts against the boss 11, forming a gap between the flat gasket and the surface of the chassis 10 or the rotating disk 20. When one end of the connecting shaft 30 presses against the flat gasket, the flat gasket can bend and deform towards the gap. Through the abutting cooperation between the boss 11 and the flat gasket, the wear of the bottom surface of the chassis 10 caused by the connecting shaft 30 can be avoided, and the flat gasket plays a role in protecting the chassis 10.

[0021] Further, a buckle groove 31 for the limiting component 40 to be buckled and connected is formed at one end of the connecting shaft 30, and a limiting platform 32 abutted against the abutting member 60 is formed at the other end of the connecting shaft 30. By buckling and connecting the buckle groove 31 of the connecting shaft 30 with the limiting component 40, the limiting platform 32 at the other end of the connecting shaft 30 is pressed against the abutting member 60.

[0022] In the above solution, the bosses 11 are annularly distributed on the surface of the chassis 10 or the rotating disk 20. Exemplarily, the connecting shaft 30 passes through the chassis 10 and the rotating disk 20 from bottom to top. The limiting component 40 is connected to the end of the connecting shaft 30, and the limiting component 40 abuts above the rotating disk 20. At this time, the bosses 11 are annularly distributed on the surface of the chassis 10 away from the limiting component 40. Further, the flat gasket abuts between the boss 11 and the end of the connecting shaft 30. And, the diameter of the ring formed by the bosses 11 is larger than the diameter of the limiting platform 32, and the diameter of the flat gasket is larger than the diameter of the ring formed by the bosses 11, so that the limiting platform 32 abuts against the abutting member 60.

[0023] In the above solution, as Figure 3As shown, a concave groove 12 is formed at the centers of the chassis 10 and the rotating disk 20, and then the limiting component 40 located above the rotating disk 20 and the abutting member 60 located below the chassis 10 are received in the concave groove 12.

[0024] Furthermore, the limiting component 40 includes a first disk 41 and a second disk 43. The first disk 41 and the second disk 43 are rotationally matched through second balls 42. The inner side of the second disk 43 is embedded in the buckle groove 31, and then the second disk 43 is buckled and connected with the buckle groove 31, so that the first disk 41 is fixedly abutted above the rotating disk 20. Then, through the second balls 42, the first disk 41 and the second disk 43 rotate relative to each other. When the rotating disk 20 rotates, the first disk 41 and the second disk 43 rotate relative to each other, and at the same time, the axial displacement of the chassis 10 and the rotating disk 20 is limited.

[0025] In the existing connection shaft 30 and the second disk 43, a threaded connection method is usually adopted, which easily causes the connection shaft 30 and the second disk 43 to become loose during the rotation of the turntable. For this reason, a clamping block 431 extending along the axial direction of the connection shaft 30 is formed on the inner side of the second disk 43. The clamping block 431 is embedded in the buckle groove 31, and then the second disk 43 is fixedly connected with the end of the connection shaft 30. Compared with the threaded connection method, the present solution adopts a buckling connection method to ensure that the second disk 43 and the connection shaft 30 will not become separated, improving the stability of the turntable operation.

[0026] Furthermore, reinforcing ribs 70 are provided on the opposite inner surfaces of the chassis 10 and the rotating disk 20, and L-shaped blocks 80 are provided on the outer surfaces of the chassis 10 and the rotating disk 20. Exemplarily, the chassis 10 and the rotating disk 20 are square, and then the L-shaped blocks 80 are symmetrically arranged at the four corners of the chassis 10 and the rotating disk 20. By providing the reinforcing ribs 70 and the L-shaped blocks 80, the support strength of the chassis 10 and the rotating disk 20 can be enhanced, and the symmetrically arranged L-shaped blocks 80 also play a role in beautification.

[0027] In summary, in the solution of the present application, a connection shaft is passed through the chassis and the rotating disk. The chassis and the rotating disk are rotationally matched through a plurality of first balls, so that the chassis and the rotating disk can rotate relative to each other. The end of the connection shaft is connected with a limiting component, and the chassis and the rotating disk are axially limited through the limiting component. A convex platform is formed on the surface of the chassis or the rotating disk away from the limiting component, and a flat abutting member is abutted between the convex platform and the connection shaft. By abutting the abutting member against the convex platform, a gap is formed between the abutting member and the surface of the chassis or the rotating disk. Then, one end of the connection shaft is pressed against the abutting member, so that the chassis and the rotating disk can contact the first balls and achieve rolling cooperation, thereby improving the load-bearing capacity of the whole structure, preventing the problem of unsmooth rotation and frequent replacement, and prolonging the service life of the turntable.

[0028] The above-described embodiments do not constitute a limitation on the protection scope of the technical solution. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the above embodiments shall be included within the protection scope of the technical solution.
