Description

Technical Field

[0001] This utility model relates to a rotating table, and more specifically, to a rotating table with stepless adjustment. Background Technology

[0002] Currently, most rotatable desktops on the market have a fixed rotation angle, only able to rotate 90° or 180°. After rotating to the corresponding angle, they need to be fixed by a locking device. This requires frequent unlocking and locking during use, making the operation cumbersome and preventing rapid rotation. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a simple, easy-to-rotate, infinitely adjustable rotating table.

[0004] The technical solution of this utility model is as follows: a infinitely adjustable rotating table includes a base, a tabletop is mounted on the base via a column, the bottom of the tabletop is provided with an annular mounting seat via an anti-loosening locking component, and a damping plate is provided at the upper end of the column, the damping plate being located between the annular mounting seat and the tabletop.

[0005] A damping rubber ring is provided between the damping plate and the annular mounting base and / or between the damping plate and the table; in the initial state, the annular mounting base or the table presses the damping rubber ring tightly against the surface of the damping plate; when the table is pushed, the annular mounting base and the damping rubber ring rotate relative to the surface of the damping plate.

[0006] In the aforementioned infinitely adjustable rotary table, the damping rubber ring is located between the damping plate and the annular mounting base, and its inner end is integrally formed with a vertical rubber sleeve. The inner wall of the vertical rubber sleeve is in close contact with the outer wall of the column; the outer wall of the vertical rubber sleeve is in close contact with the inner wall of the annular mounting base.

[0007] In the aforementioned infinitely adjustable rotating table, the annular mounting base includes a positioning ring disposed at the bottom of the tabletop. The inner diameter of the positioning ring is adapted to the outer diameter of the damping rubber ring. A mounting ring plate is detachably disposed at the lower end of the positioning ring. The damping plate and the damping rubber ring are located between the mounting ring plate and the tabletop.

[0008] In the aforementioned infinitely adjustable rotating table, a mounting cover is detachably provided at the bottom of the tabletop, and the annular mounting seat is set at the bottom of the mounting cover by a locking assembly; an indexing plate is fixedly provided on the damping plate, and the indexing plate is provided with a plurality of scale teeth, which are located inside the mounting cover; an elastic positioning assembly that cooperates with the scale teeth is provided inside the mounting cover.

[0009] In the aforementioned infinitely adjustable rotary table, the locking assembly includes several through holes provided on the mounting cover and the annular mounting base, an anti-loosening nut fixedly provided inside the mounting cover opposite to the through holes, and a mounting screw provided inside the through holes.

[0010] In the aforementioned infinitely adjustable rotary table, the elastic positioning component includes a mounting bracket disposed within a mounting cover. The front end of the mounting bracket is located above the indexing plate. A vertical mounting groove is provided at the bottom of the front end of the mounting bracket. A conical positioning block that mates with the scale teeth is movably disposed within the vertical mounting groove. A tension spring is provided between the conical positioning block and the bottom surface of the vertical mounting groove.

[0011] In the aforementioned infinitely adjustable rotating table, the column is located near the end of one side of the base.

[0012] In the aforementioned infinitely adjustable rotating table, the column is a hollow sleeve, a lifting cylinder is movably installed inside the column, the damping plate is installed at the upper end of the lifting cylinder, and a gas spring that cooperates with the lifting cylinder is provided inside the column.

[0013] With the above-mentioned structure, the tabletop can rotate 360° on the column by the cooperation of the annular mounting base and the damping plate. The damping rubber ring provides frictional damping to restrict the tabletop, which needs to be pushed by a sufficiently large force to rotate, ensuring that the tabletop will not rotate arbitrarily during use. No additional fixing structure is required, the structure is simple and the operation is convenient.

[0014] Meanwhile, by adjusting the tightness of the locking components, the clamping force on the damping rubber ring can be changed, thus altering the magnitude of the friction provided by the damping rubber ring, thereby adjusting the amount of force required to push the tabletop.

[0021] See Figure 1-4 As shown, the present invention provides a steplessly adjustable rotating table, including a base 1, a tabletop 3 mounted on the base 1 via a column 2, an annular mounting seat 5 at the bottom of the tabletop 3 via an anti-loosening locking assembly 4, and a damping plate 6 at the upper end of the column 2, the damping plate 6 being located between the annular mounting seat 5 and the tabletop 3.

[0022] A damping ring 7 is provided between the damping plate 6 and the annular mounting base 5 and / or between the damping plate 6 and the table 3. In the initial state, the annular mounting base 5 or the table 3 presses the damping ring 7 tightly against the surface of the damping plate 6. When the table 3 is pushed, the annular mounting base 5 and the damping ring 7 rotate relative to the surface of the damping plate 6. The rotation structure formed by the cooperation of the annular mounting base and the damping plate allows the table to rotate 360° arbitrarily on the column, while the damping ring provides frictional damping to restrict the table.

[0023] The damping rubber ring provides friction between the damping plate and the tabletop, ensuring that the force exerted during daily use, such as writing or picking up items, makes rotation difficult. A significant pushing force from the user is required for rotation, guaranteeing the tabletop won't rotate unnecessarily during use. This structure eliminates the need for additional fixing mechanisms to secure the tabletop, making it simple, easy to operate, and eliminating the need for frequent unlocking and locking.

[0024] Meanwhile, by adjusting the tightness of the locking components, the clamping force on the damping rubber ring can be changed, thus altering the magnitude of the friction provided by the damping rubber ring, thereby adjusting the amount of force required to push the tabletop.

[0025] In this embodiment, the damping rubber ring 7 is located between the damping plate 6 and the annular mounting base 5, and its inner end is integrally formed with a vertical rubber sleeve 8. The inner wall of the vertical rubber sleeve 8 is tightly attached to the outer wall of the column 2; the outer wall of the vertical rubber sleeve 8 is tightly attached to the inner wall of the annular mounting base 5. The vertical rubber sleeve increases the contact area between the damping rubber ring and the outer wall of the column, improving friction and making the tabletop more stable during use. Simultaneously, increasing the width of the damping rubber ring prevents it from tilting and jamming during rotation, ensuring smooth rotation.

[0026] In this embodiment, preferably, the annular mounting base 5 includes a positioning ring 5a disposed at the bottom of the tabletop 3. The inner diameter of the positioning ring 5a is adapted to the outer diameter of the damping rubber ring 7. A mounting ring plate 5b is detachably disposed at the lower end of the positioning ring 5a. The damping plate 6 and the damping rubber ring 7 are located between the mounting ring plate 5b and the tabletop 3. This structure facilitates the installation and removal of the annular mounting base and the damping rubber ring.

[0027] In this embodiment, preferably, the bottom of the tabletop 3 is detachably provided with a mounting cover 9, and the annular mounting base 5 is set at the bottom of the mounting cover 9 by a locking assembly 4; a scale plate 10 is fixedly provided on the damping plate 6, and the scale plate 10 is provided with a plurality of scale teeth 11, which are located inside the mounting cover 9; the mounting cover 9 is provided with an elastic positioning assembly 12 that cooperates with the scale teeth 11. The angle of the scale teeth is set according to actual usage requirements. By setting the scale plate and the elastic positioning assembly, the angle of rotation of the tabletop is positioned, and the user can select the angle according to actual needs.

[0028] More preferably, the locking assembly 4 includes several through holes 4a disposed on the mounting cover 9 and the annular mounting base 5. An anti-loosening nut 4b, opposite to the through holes 4a, is fixedly disposed inside the mounting cover 9, and a mounting screw 4c is disposed within the through holes 4a. The swaying and vibration generated during the rotation of the tabletop can cause the mounting screws to rotate slightly, potentially leading to loosening. The anti-loosening nut prevents the mounting screws from loosening during use. The anti-loosening nut is a conventional technology, and its specific structure and working principle are common knowledge to those skilled in the art, and will not be described in detail here.

[0029] In this embodiment, preferably, the elastic positioning component 12 includes a mounting bracket 12a disposed within the mounting cover 9. The front end of the mounting bracket 12a is located above the indexing plate 10. A vertical mounting groove 12b is provided at the bottom of the front end of the mounting bracket 12a. A conical positioning block 12c that movably engages with the scale teeth 11 is disposed within the vertical mounting groove 12b. A tension spring 12d is provided between the conical positioning block 12c and the bottom surface of the vertical mounting groove 12b. The upper surface of the scale teeth is set as an arc-shaped surface to facilitate the passage of the conical positioning block.

[0030] In the initial state, the front end of the conical positioning block is located in the gap between two adjacent scale teeth. When rotating, after the conical positioning block passes through the scale teeth and reaches the next gap, it will strike the surface of the indexing plate under the reset action of the tension spring, making a sound to remind the user to rotate into place.

[0031] In this embodiment, preferably, the upright 2 is located near the end of one side of the base 1. With this structure, when the user is sitting on a sofa, the base can be inserted into the bottom of the sofa from the side, so that the tabletop is positioned above the sofa, providing a comfortable user environment. Similarly, it can also be used for some structurally suitable beds or other chairs.

[0032] In this embodiment, the column 2 is a hollow sleeve, and a lifting cylinder 13 is movably disposed within the column 2. The damping plate 6 is disposed at the upper end of the lifting cylinder 13, and a gas spring 14 that cooperates with the lifting cylinder 13 is provided inside the column 2. The lifting function of the tabletop is achieved by setting up the gas spring and the lifting cylinder, which can adapt to more usage environments. A pressure rod or other components that cooperate with the end of the gas spring are provided at the bottom of the tabletop to control the opening and closing of the gas spring. This is a common lifting structure and is common knowledge to those skilled in the art, and will not be described in detail here.

[0033] When in use, place the base in a suitable position, and adjust the height of the tabletop according to the height of the seat using the gas spring. When the user needs to rotate the tabletop, simply push the tabletop.

[0034] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
