Description

Technical Field

[0001] The utility model belongs to the technical field of dining turntables, and in particular relates to a dining table turntable ring. Background Art

[0002] At present, whether in a home or restaurant, a turntable is generally placed on a larger dining table, and then a glass or wooden tabletop is placed on the turntable, and the dishes are placed on the tabletop, which is convenient for users to rotate and pick up the dishes. Due to the convenience and practicality of rotating dining tables, more and more rotating dining tables have come out, so turntables with different rotating mechanisms have also appeared. Some traditional turntables for dining tables adopt a combination structure of inner and outer rings, and some adopt a combination structure of upper and lower circles; turntables with a combination structure of inner and outer circles, such as stainless steel, aluminum alloy, etc., have exposed steel balls when in use, which are easy to hide dust, and the steel balls are easy to rust. After the weight of the tabletop is too heavy, it becomes inflexible and prone to jamming; turntables with upper and lower circle structures, such as plastic turntables, are noisy, not durable, and easy to age. At the same time, traditional turntables cannot be fixed on wooden tabletops.

[0003] To this end, a dining table turntable with announcement number "CN210353711U" comprises: an upper cover, a lower cover, a plurality of ball bearings and a plurality of sliding columns, wherein the lower cover is installed at the bottom of the upper cover; the middle position of the bottom wall of the lower cover is concave to form an annular lower cover trapezoidal groove, the ball bearings and the sliding columns are arranged in the lower cover trapezoidal groove at intervals, and the ball bearings are in contact with the two side surfaces and the bottom surface of the lower cover trapezoidal groove; both sides of the upper cover top wall near the middle position are concave downward to form a convex upper cover trapezoidal groove in the middle position, the lower cover trapezoidal groove has the same structure as the upper cover trapezoidal groove and is aligned in the upper and lower positions, and the ball bearings are in contact with the two side surfaces and the top surface of the upper cover trapezoidal groove, and the trapezoidal grooves are provided on the upper cover and the lower cover of the turntable to form a slide rail for the plastic ball, so that the contact area between the plastic ball and the slide rail is small, so that the turntable can rotate flexibly, and has the advantages of low noise, good stability, simple structure, etc.

[0004] However, for the above-mentioned dining table turntable, although the flange of the lower cover is located in the cavity formed by the bending of the side wall of the upper cover, and the flange of the lower cover does not contact with the flange of the upper cover. This design can not only prevent dust and other debris from entering the turntable and causing jamming, but there are still the following obvious defects during use: the upper and lower covers will produce a certain downward pressure deformation under pressure, so that the flange of the lower cover and the flange of the upper cover will produce contact friction when deforming, so that the upper and lower covers cannot rotate smoothly and get stuck during the rotation of the dining table. Summary of the invention

[0005] The purpose of the utility model is to provide a dining table turntable ring to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dining table turntable ring, comprising:

[0008] A stabilizing sleeve, wherein a rolling ball is movably provided on the inner side of the stabilizing sleeve through a limiting circular cavity, and strip plates for fixing the stabilizing sleeve are provided at both ends of the outer side of the stabilizing sleeve. The stabilizing sleeve is arranged in a lower slide groove in the supporting groove through the rolling ball, and an upper slide groove in the shape of an arc is stamped on the inner side of the annular upper cover corresponding to the upper end of the rolling ball.

[0009] Preferably, the annular upper cover is slidably arranged on the inner side of the supporting groove and is movably limited by an anti-slip limit ring. The surface of the anti-slip limit ring is evenly provided with limit embedding holes. The ball movably limits the ring and is rollingly supported in the limit embedding holes. The annular upper cover and the annular bottom cover can maintain smooth rotation when under pressure without getting stuck.

[0010] Preferably, the stabilizing sleeve, rolling balls and strip plates are combined to form an auxiliary rolling component that enables the annular upper cover to rotate on the annular bottom cover, and the auxiliary rolling component is evenly arranged inside the supporting groove, and a fixed hole is provided at one end of the auxiliary rolling component, so that the auxiliary ball component can be evenly arranged in the lower slide groove to provide rotational support for the annular upper cover.

[0011] Preferably, limit clamp groove cavities are extended outward on both sides of the support groove, and the annular upper cover is rotated in the support groove by means of the matching movable clamping of the anti-slip limit ring and the limit clamp groove cavity, so that the annular upper cover can remain stable during the rotation process and will not fall off the support groove in the annular bottom cover.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides a technical solution: a dining table turntable ring, comprising:

[0020] The annular bottom cover 1 is provided with a support groove 2 stamped into a T-shaped structure, which is conducive to the annular upper cover 5 rotating in the support groove 2 in the annular bottom cover 1 using a rolling ball 8, so that the dining table can rotate smoothly. The center position of the bottom end of the inner bottom of the support groove 2 is stamped downward to form an arc-shaped lower slide groove 3, so that the rolling ball 8 can slide directionally in the lower slide groove 3 to ensure the rolling stability of the rolling ball 8. The inner side of the upper end of the annular bottom cover 1 and the inner side of the support groove 2 are provided with an annular upper cover 5, which can make the annular upper cover 5 slide on the inner side of the support groove 2. The dining table rotates in the support groove 2 in the annular bottom cover 1, so that the rotation is smoother and the stability of the rotation is enhanced. The bottom sides of both ends of the annular upper cover 5 are provided with anti-slip limit rings 6 extending outward to the two ends of the inner side of the support groove 2, so that the annular upper cover 5 can rotate stably on the annular bottom cover 1. The anti-slip limit ring 6 is movably penetrated by a ball 11 that is conducive to the sliding of the annular bottom cover 1. The ball 11 is made of steel material and has a strong stable support. It supports the anti-slip limit ring 6 in the limit clamp groove cavity 4, which is conducive to the smooth sliding of the annular upper cover 5.

[0021] The stabilizing sleeve 7 has a rolling ball 8 movably provided on the inner side of the stabilizing sleeve 7 through a limiting circular cavity 14, and the rolling ball 8 is made of plastic material, so that the annular upper cover 5 can slide smoothly and stably on the inner side of the annular bottom cover 1, and strip plates 9 for fixing the stabilizing sleeve 7 are provided at both ends of the outer side of the stabilizing sleeve 7, so that the rolling ball 8 can be positioned on the inner side of the supporting groove 2 to avoid the problem of escaping from the lower slide groove 3 during rotation. The stabilizing sleeve 7 is arranged in the lower slide groove 3 in the supporting groove 2 through the rolling ball 8, so that the rotation of the annular upper cover 5 in the annular bottom cover 1 becomes more stable, and the upper end of the rolling ball 8 is stamped with an arc-shaped upper slide groove 10 corresponding to the inner side of the annular upper cover 5, so that the rolling ball 8 can be movably limited between the inner side of the annular upper cover 5 and the annular bottom cover 1 to avoid the phenomenon of escaping from the slide.

[0022] The annular upper cover 5 is slidably arranged on the inner side of the support groove 2 and is movably limited by the anti-slip limit ring 6, so as to avoid the phenomenon of the annular upper cover 5 rotating unsteadily and shaking, and improve the stability of the annular upper cover 5 being limited on the inner side of the annular bottom cover 1. The surface of the anti-slip limit ring 6 is evenly provided with limit embedding holes 12, so that the ball 11 can be movably embedded in the limit embedding holes 12, and will not be separated from the limit embedding holes 12 when rolling, thereby ensuring the stability of the ball 11 rolling in the limit clamp groove cavity 4. The ball 11 is movably limited in the limit embedding hole 12, which effectively prevents the anti-slip limit ring 6 and the limit clamp groove cavity 4 from being compressed and deformed to generate friction. The stabilizing sleeve 7, rolling ball 8, and strip plate 9 are combined to form an auxiliary rolling component that enables the annular upper cover 5 to rotate on the annular bottom cover 1, and the auxiliary rolling component is evenly arranged inside the supporting groove 2, which is beneficial to the stable and smooth rotation of the annular upper cover 5, and one end of the auxiliary rolling component is provided with a fixing hole 13, which is beneficial to the positioning of the rolling ball 8 and prevents derailment. The two sides of the supporting groove 2 are extended outward to form a limit clamp groove cavity 4. The annular upper cover 5 is rotated in the supporting groove 2 through the matching and active clamping of the anti-slip limit ring 6 and the limit clamp groove cavity 4, thereby limiting the annular upper cover 5 and ensuring the stability of the rotation of the dining table using the annular upper cover 5.

[0023] Specifically, when in use, first, the stabilizing sleeve 7, rolling ball 8, and strip plate 9 are combined to form an auxiliary rolling component that enables the annular upper cover 5 to rotate on the annular bottom cover 1, and is fixed in the supporting groove 2 and is located in the lower slide groove 3. Then the annular upper cover 5 is movably arranged in the supporting groove 2 set in the annular bottom cover 1, and the anti-slip limit ring 6 set at the bottom ends of both sides of the annular upper cover 5 is rotated in the limit clamp groove cavity 4, and at the same time, the upper and lower ends of the balls 11 in the limit embedding holes 12 are rollingly supported in the limit clamp groove cavity 4, so that when the annular upper cover 5 rotates in the supporting groove 2 by means of the auxiliary rolling component, the balls 11 can be rollingly supported in the limit clamp groove cavity 4, so that there will be no deformation friction and rotation jamming between the anti-slip limit ring 6 and the limit clamp groove cavity 4 after force is applied, so that the annular upper cover 5 can rotate normally and smoothly after being applied with force, and at the same time, the stability and smoothness of the rotation between the annular upper cover 5 and the annular bottom cover 1 after being applied with force can be enhanced.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
