[0026] As Figure 1 、 2 、3, 4 shown, it is a tabletop rotation structure of a desk of the present utility model, which includes a mounting base 20, a rotating base 10, and a positioning disk 30. The rotating base 10 is fixedly matched with the tabletop 70 of the desk. The mounting base 20 is connected to the base of the desk. The rotating base 10 is pivotally matched with the mounting base 20. The rotating base 10 can rotate relative to the mounting base 20 about an axis O extending vertically, and then the tabletop 70 can rotate relative to the mounting base 20 about the axis O. The positioning disk 30 is installed between the rotating base 10 and the mounting base 20, and the positioning disk 30 is fixedly matched with the mounting base 20. A plurality of first positioning grooves 32 arranged around the axis O and a plurality of second positioning grooves 33 arranged around the axis O are provided on the positioning disk 30. A first elastic locking member 40 and a second elastic locking member 50 are installed on the rotating base 10. The first elastic locking member 40 can move in the up and down direction to be clamped in one of the first positioning grooves 32, and the second elastic locking member 50 can move in a direction perpendicular to the axis O (i.e., the horizontal direction) to be clamped in one of the second positioning grooves 33.
[0027] In the present utility model, the rotating seat 10 is pivotally connected to the mounting seat 20, enabling the table top panel 70 to rotate relative to the base of the office desk about the axis O, achieving an adjustable rotation angle of the table top panel 70 to meet the space arrangement of the office desk and the personalized usage requirements of the user. After adjusting the table top panel 70 to an appropriate angle, the first elastic locking member 40 and the second elastic locking member 50 respectively cooperate with the first positioning groove 32 and the second positioning groove 33 on the positioning disk 30, so that the table top panel 70 with the adjusted angle is fixed to the mounting seat 20. The first elastic locking member 40 and the first positioning groove 32 lock the rotating seat 10 in the vertical direction, and the second elastic locking member 50 and the second positioning groove 33 lock the rotating seat 10 in the horizontal direction, enabling the table top panel 70 to maintain a better stable state during use.
[0028] On the upper surface of the positioning disk 30, there is a circular boss 31 protruding upward. The rotating seat 10 is fixedly connected to the lower surface of the table top panel 70 and is located above the positioning disk 30. A through hole 11 is provided in the middle of the rotating seat 10, and the circular boss 31 is embedded in the through hole 11, so that the positioning disk 30 is pivotally engaged with the rotating seat 10, and then the mounting seat 20 fixedly engaged with the positioning disk 30 is pivotally engaged with the rotating seat 10. The above-mentioned axis O is the central axis of the circular boss 31, so that after the circular boss 31 is installed in cooperation with the through hole 11, the rotating seat 10 can rotate relative to the mounting seat 20 about the axis O. A plurality of first positioning grooves 32 are provided on the upper surface of the positioning disk 30, that is, the first positioning grooves 32 are recessed downward from the upper surface of the positioning disk 30. Thus, the first elastic locking member 40 provided on the rotating seat 10 is located above the first positioning groove 32 and can be snapped into the first positioning groove 32 after moving in the vertical direction. A plurality of second positioning grooves 33 are provided on the outer peripheral surface of the circular boss 31, that is, the second positioning grooves 33 are recessed from the outer peripheral surface of the circular boss 31 along the radial direction of the positioning disk 30 towards the axis O. In this way, the second elastic locking member 50 can be snapped into the second positioning groove 33 after moving in the radial direction of the positioning disk 30.
[0029] The first elastic locking member 40 includes a housing 42, a steel ball 41, and a first spring 43. Among them, the housing 42 is fixedly connected to the rotating seat 10. An opening is provided at the bottom of the housing 42. The steel ball 41 is located inside the housing 42 and at the opening of the housing 42, and a part of it extends out from the opening of the housing 42. The size of the opening of the housing 42 is set to prevent the steel ball 41 from falling out of the opening. The first spring 43 is located inside the housing 42. Its upper end abuts against the upper end of the housing 42, and its lower end abuts against the top of the steel ball 41. Thus, an elastic stress is applied to the steel ball 41 downward by the first spring 43 to ensure that the steel ball 41 always has a tendency to move downward. When the steel ball 41 is aligned with the first positioning groove 32 in the circumferential direction of the positioning disk 30, the part of the steel ball 41 extending out of the opening of the housing 42 can be embedded into the first positioning groove 32. In the present utility model, a plurality of the above-mentioned second elastic locking members 50 can be installed on the rotating seat 10 to increase the damping force when the rotating seat 10 rotates relative to the mounting seat 20, and then improve the stability of the tabletop 70 after being adjusted in place.
[0030] The second elastic locking member 50 includes a locking block 51 and a second spring 52. A sliding groove 12 is provided on the rotating seat 10. The sliding groove 12 extends along the radial direction of the positioning disk 30, and its inner end communicates with the through hole 11. The locking block 51 is slidably installed inside the sliding groove 12. The second spring 52 is located in the sliding groove 12. One end of it abuts against the end of the locking block 51 away from the circular boss 31, and the other end abuts against the outer end wall of the sliding groove 12. An elastic stress is applied to the locking block 51 by the second spring 52 to make the locking block 51 always maintain a tendency to move towards the circular boss 31. One end of the locking block 51 close to the circular boss 31 forms a locking boss 511 whose shape matches that of the second positioning groove 33. On the premise that the locking block 51 always maintains a tendency to move towards the circular boss 31, the locking boss 511 can be snapped into one of the second positioning grooves 33. In this way, a part of the locking block 51 is held in the sliding groove 12, and the other part is snapped into the second positioning groove 33, limiting the rotational freedom of the rotating seat 10 relative to the positioning disk 30.
[0031] A fixing hole 21 is provided on the mounting seat 20. A positioning boss 35 protruding downward is provided on the lower surface of the positioning disk 30. The positioning boss 35 is embedded in the fixing hole 21. The cross-sections of the positioning boss 35 and the fixing hole 21 are both hexagonal. After the positioning boss 35 is embedded into the fixing hole 21, it can prevent the positioning boss 35 from rotating relative to the mounting seat 20, limiting the rotational freedom of the positioning disk 30 relative to the mounting seat 20. The cross-sectional shapes of the positioning boss 35 and the fixing hole 21 can also be triangular, square, etc. In addition, a connecting component extending up and down penetrates the positioning disk 30 and the mounting seat 20, and the connecting component is used to limit the freedom degree of the mounting seat 20 and the positioning disk 30 in the height direction, thereby fixing the positioning disk 30 on the mounting seat 20.
[0032] The connecting component specifically includes a nut 62, a screw 61, a lower gasket 63 and an upper gasket 64. The nut 62 and the screw 61 form a locking screw. The upper gasket 64 is placed above the circular boss 31, and the lower gasket 63 is located below the mounting seat 20. The nut 62 is screwed onto the screw 61, and the end head of the nut 62 presses on the upper gasket 64, and the end head of the screw 61 presses on the lower surface of the lower gasket 63. During assembly, the nut 62 is sequentially passed through the upper gasket 64 and the hole reserved in the middle of the positioning disk 30 from top to bottom, and the screw 61 is passed through the lower gasket 63 and the hole reserved in the middle of the positioning disk 30 from bottom to top. The screw 61 is tightened to press the upper gasket 64 and the lower gasket 63 tightly, and the positioning disk 30 is fixed to the mounting seat 20, making it easy to assemble the positioning disk 30 and the mounting seat 20. In order to facilitate the assembly of the pivotal cooperation between the rotating seat 10 and the mounting seat 20, in the present utility model, the outer edge of the upper gasket 64 protrudes from the outer peripheral surface of the circular boss 31, so that a limiting groove is formed between the part of the upper gasket 64 protruding from the circular boss 31 and the upper surface of the positioning disk 30. The rotating seat 10 is in a plate shape and is fixed to the lower surface of the table top panel 70 by screws or other detachable means. The part of the rotating seat 10 located on the outer peripheral edge of the through hole 11 is embedded in the limiting groove to prevent the rotating seat 10 from moving relative to the positioning disk 30 in the up and down directions, and at the same time ensure that the rotating seat 10 can rotate relative to the positioning disk 30; during assembly, the upper gasket 64 and the nut 62 are placed in the avoidance groove 701 preset on the lower surface of the table top panel 70, then the rotating seat 10 is fixed to the lower surface of the table top panel 70 by using screws, and then the circular boss 31 of the positioning disk 30 is embedded into the through hole 11 from bottom to top, and the nut 62 is inserted into the hole preset in the middle of the positioning disk 30, then the mounting seat 20 is placed below the positioning disk 30, so that the positioning boss 35 of the positioning disk 30 is embedded into the fixing hole 21 of the mounting seat 20, and finally the screw 61 is passed through the lower gasket 63 from bottom to top and then into the nut 62, and the screw 61 is tightened to complete the assembly; on the upper surface of the circular boss 31, there is a positioning post 34 protruding upward, and on the upper gasket 64, there is a positioning hole 65. The positioning post 34 is inserted into the positioning hole 65 to prevent the upper gasket 64 from rotating relative to the positioning disk 30, thereby avoiding the upper gasket 64 driving the nut 62 to rotate and causing the nut 62 and the screw 61 to become loose.
[0033] It should be noted that in the above structure, the positioning disk 30 and the mounting seat 20 are fixedly matched, and the first elastic locking member 40 and the second elastic locking member 50 are installed on the rotating seat 10. In other embodiments, it is also possible to fixedly match the positioning disk 30 and the rotating seat 10 and install the first elastic locking member 40 and the second elastic locking member 50 on the mounting seat 20.
[0034] The office desk of the present utility model includes the table top panel rotation structure of the above office desk, and the other structures of the office desk are the same as those in the prior art and will not be described in detail here.
[0035] Finally, it should be noted that the above embodiments are only optional embodiments of the present utility model, and the protection scope of the present utility model cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model fall within the protection scope required by the present utility model.
