Description

Technical field

[0001] The invention relates to the technical field of rail accessories, in particular to a turntable for a cabinet, which comprises a turntable having a specially shaped sliding groove and a second rotation axis, and a base plate having a limiting groove and a first rotation axis. After assembly, the first rotation axis is movably inserted in the specially shaped sliding groove, and the second rotation axis is movably inserted in the limiting groove. After installation in the cabinet, the turntable can store various objects. By rotating 360 degrees for extraction, the objects are quickly accessible from all directions, thereby improving convenience during use. State of the art

[0002] Generally, kitchen cabinets are mainly used to store various spices or tableware for food. However, there is a certain gap between the deeper space of the cabinet interior and the opening, which is inconvenient for users to take out or place necessary items. This is why turntables for cabinets were developed. Most turntables are equipped with a rotating axis and a slide rail. The slide rail allows the turntable to be moved from the inside of the cabinet to the outside and then rotated around the rotating axis. Therefore, the user can pick up or place objects on the turntable and then return the turntable to the interior.

[0003] In order to avoid wasting internal space and prevent the turntable from hitting the inner wall of the cabinet during rotation and preventing it from rotating out, multiple connecting rods are often designed to modify the slide rail to allow the turntable to rotate out smoothly, but this results in an overly complicated design of the existing turntable structure. By connecting and linking various components, the user can pull the turntable in the horizontal direction and then rotate it to a certain extent. Only through the complex rotation relationship described above can the turntable rotate out smoothly. The previous turntables all have too many components and overly complicated structures, which requires more manpower, material resources, and time during manufacturing and assembly, thus reducing production efficiency.Therefore, the task of how to effectively simplify the structure and reduce the number of components to improve production efficiency is currently an area where manufacturers are eagerly pursuing improvements.

[0004] In addition, the traditional design of the turntable also has some disadvantages in use. For example, when the turntable is driven to a translational or rotational motion by the connecting rods, it is very likely to cause deformation due to excessive load, and the supporting force is obviously insufficient to prevent tilt, resulting in uneven sliding of the turntable and easy to malfunction during use. In view of this, through active development, research, and improvement based on the above-mentioned disadvantages and based on many years of manufacturing and production experience, the inventor has developed a turntable for a cabinet, which includes a turntable with a specially shaped sliding groove and a second rotation axis, and a fixing base with a limiting groove and a first rotation axis.After assembly, the first pivot axis is movably inserted into the specially designed sliding groove, and the second pivot axis is movably inserted into the limit groove. Installed inside the cabinet, it can store various objects. It can be pulled out and returned to its original position by rotating 360 degrees, allowing you to retrieve objects in different directions, thus improving user convenience. Object of the invention

[0005] The object of the invention is to provide a turntable for a cabinet, comprising a mounting base, a turntable, and a plate. The mounting base has a long, strip-shaped limiting groove in the center and a first rotation axis near the mounting side. The turntable is mounted on one side of the mounting base, with a second rotation axis and a specially shaped sliding groove with a closed design provided in the central region of the underside of the plate, with the first rotation axis movably inserted in the specially shaped sliding groove and the second rotation axis movably inserted in the limiting groove. Various objects can be stored on the plate.The 360-degree rotation for extraction allows objects to be quickly accessed in all directions, thereby simplifying components, reducing assembly and manufacturing costs, and improving comfort during use.

[0006] This object is achieved by the turntable for a cabinet of the invention, which is installed in the cabinet to store various objects and can be pulled out and returned to its original position by rotating 360 degrees to take out objects lying in different directions, comprising: a fixing base having a rectangular plate structure, the fixing base constituting a mounting side corresponding to the front side of the cabinet and being fixed on the bottom surface of the interior of the cabinet such that the mounting side is located on the front side of the cabinet, a long, strip-shaped restricting groove being provided in the center of the fixing base, the extending direction of the restricting groove being perpendicular to the mounting side, and a first rotation axis being provided near the mounting side;a rotary plate mounted on one side of the fixing base, wherein a second rotary axis and a specially shaped sliding groove with a closed design are provided in the central region of the bottom of the rotary plate, wherein the first rotary axis is movably inserted in the specially shaped sliding groove and the second rotary axis is movably inserted in the limiting groove, and a cup fixedly mounted on the rotary plate and rotates together with the rotary plate. When the cup is pulled, the first rotary axis slides limitedly along the specially shaped sliding groove to rotate, and the second rotary axis slides limitedly along the limiting groove, so that the rotary plate performs 360-degree rotation relative to the fixing base and a translational movement to be pulled out. Here, the first rotary axis and the second rotary axis are bearing rollers.

[0007] In one embodiment, the turntable for a cabinet further comprises two wings, each extending from two sides of the mounting base and flush with the mounting side to facilitate positioning on the floor of the cabinet. The specially shaped sliding groove consists of a pair of first curved sections with a smaller curvature and a pair of second curved sections with a larger curvature, wherein the turntable generates translational movements with different distances when the first rotation axis passes through the first curved sections and the second curved sections. A bending section is formed at the junctions of the first curved sections and the second curved sections, so that the first rotation axis can carry the plate to rotate when it passes through a bending section.When the rotary plate performs a translational movement, the length of the limit groove corresponds to the outward translation distance required for the rotary plate.

[0008] In another embodiment, the turntable for a cabinet further comprises a plurality of spacers arranged on the underside of the turntable and lying on the mounting base to reduce the contact area between the turntable and the mounting base.

Ways to implement the invention

[0009] In order that the content of the invention is clearly understood, the invention will be described below with reference to the accompanying drawings.

[0010] Fig.1, 2, 3, and 4 to 6 show exploded views, a perspective view after assembly, and illustrations of the operating state of the preferred embodiment of the invention. As shown in the above figures, the turntable 1 for a cabinet of the invention is installed in the cabinet 2 to store various objects. It can be pulled out and returned to its original position by rotating 360 degrees to retrieve objects lying in different directions. The turntable 1 of the cabinet includes a mounting base 11, a rotating plate 12, and a tray 13.

[0011] The mounting base 11 has a rectangular plate structure. The mounting base 11 forms a mounting face 111 at the front side corresponding to the cabinet 2 and is fixed to the bottom surface of the interior of the cabinet 2 such that the mounting face 111 is located on the front side of the cabinet 2. A long, strip-shaped restricting groove 112 is provided in the center of the mounting base 11. The extending direction of the restricting groove 112 is perpendicular to the mounting face 111. A first rotation axis 113 is provided near the mounting face 111. Note that the turntable 1 of the cabinet of the invention also has two wings 114, each extending from two sides of the mounting base 11 and flush with the mounting face 111.

[0012] The rotating plate 12 is mounted on one side of the mounting base 11. A second rotating shaft 121 and a specially shaped sliding groove 122 with a closed design are provided in the central region of the bottom of the plate 12. The first rotating shaft 113 is movably inserted in the specially shaped sliding groove 122, and the second rotating shaft 121 is movably inserted in the restricting groove 112. The first rotating shaft 113 and the second rotating shaft 121 are bearing rollers and have good lubricating properties, providing a smooth feel during operation.

[0013] The plate 13 is fixedly mounted on the rotating plate 12 and forms a storage space 131 on its upper side for inserting objects, so that the plate 13 rotates together with the rotating plate 12.

[0014] The specially shaped sliding groove 122 of the invention consists of a pair of first curved sections 1221 with a smaller curvature and a pair of second curved sections 1222 with a larger curvature. Their shape resembles a cloud. The rotating plate 12 generates translational movements with different distances when the first rotation axis 113 passes through the first curved sections 1221 and the second curved sections 1222. A bending section 1223 is formed at each of the junctions of the first curved sections 1221 and the second curved sections 1222, so that the first rotation axis 113 can drive the plate 12 to rotate when it passes through a bending section 1223. During the translational movement, the second rotation axis 121 is restricted by the restriction groove 112 and can only move a predetermined distance.Therefore, when the rotary plate 12 performs a translational movement, the length of the limiting groove 112 corresponds to the outward translational distance required for the rotary plate 12. Furthermore, the rotary table 1 for a cabinet of the invention includes a plurality of spacers 14 arranged on the underside of the rotary plate 12 and resting on the mounting base 11 to reduce the contact area between the rotary plate 12 and the mounting base 11.

[0015] The actual use of the turntable 1 for a cabinet of the invention can be divided into two parts: First, when the turntable 13 is pulled out, the first rotation axis 113 can slide to a limited extent along the specially shaped sliding groove 122 and thus rotate, and the second rotation axis 121 can slide linearly to a limited extent along the limiting groove 112, so that the turntable 12 performs a 360-degree rotation relative to the mounting base 11 and a translational movement to be pulled out. The 360-degree rotation for pulling out allows objects to be quickly accessed in all directions, thereby simplifying components, reducing assembly and manufacturing costs, and improving comfort during use.
