[0029] Such as Figure 1 , 2, 3, 4, 5, and 6 show a flip angle adjustment structure of a desk desktop of the utility model, which includes a rotating seat 10, a mounting seat 20, and a locking member 40, wherein the rotating seat 10 is installed below the desk desktop 60 for work, the mounting seat 20 is fixedly connected to the base 70 of the desk, a rotating shaft 30 extending horizontally (left and right directions in the figure) passes through the rotating seat 10 and the mounting seat 20, and the rotating seat 10 and the mounting seat 20 are pivotally connected together so that the desk desktop 60 can be flipped relative to the base 70, the locking member 40 is movably mounted on the rotating seat 10, and a plurality of card slots 211 are provided on the mounting seat 20, and the plurality of card slots 211 are arranged along the rotating shaft 30 The two adjacent card slots 211 are arranged circumferentially, and are connected by a through slot 212, wherein the width of the card slot 211 is greater than the width of the through slot 212, which can be regarded as a slot extending along an arc track provided on the mounting seat 20, and the slot is continuously composed of a plurality of card slots 211 with a larger width and a through slot 212 with a smaller width arranged at intervals, and the locking member 40 is movably connected to the rotating seat 10, so that the locking member 40 can move between the first position and the second position along the left-right direction relative to the rotating seat 10, and the locking member 40 passes through the above-mentioned slot while passing through the rotating seat 10, and a locking portion 401 and a neck portion 402 are provided thereon, and when the locking member 40 is in the first position The locking portion 401 is embedded in one of the slots 211, and the two sides of the through slot 212 respectively form limiting portions to prevent the locking portion 401 from sliding between two adjacent slots 211 through the through slot 212. At this time, the locking portion 401 cooperates with the slot 211 to limit the degree of freedom of rotation of the rotating seat 10 relative to the mounting seat 20. When the locking member 40 moves horizontally from the first position to the second position in the left-right direction, the locking portion 401 is staggered with the slot 211 in the left-right direction, so that the neck portion 402 moves to a position inside the slot 211, and the through slot 212 allows the neck portion 402 to slide into it, and then the neck portion 402 can pass through the through slot 212 and move between adjacent The locking member 40 can slide between the two slots 211, that is, the necking portion 402 can slide freely inside the continuously extended groove formed by the multiple slots 211 and the multiple through slots 212. That is to say, when the locking member 40 is in the second position, since the locking portion 401 is staggered with the slot 211 in the left and right directions and the necking portion 402 is placed in the slot 211, the locking member 40 no longer limits the freedom of rotation of the rotating base 10 relative to the mounting base 20. At this time, the desktop panel 60 can be flipped to the required angle, and then the locking member 40 is moved back to the first position so that the locking member 40 is inserted into the corresponding slot 211, so that the desktop panel 60 is fixed and maintained at the adjusted angle.

[0030] In the present invention, the locking member 40 moves laterally so that the locking portion 401 can move between a position located in the slot 211 and a position offset from the slot 211, and when the locking portion 401 is in a position offset from the slot 211, the neck portion 402 on the locking member 40 is aligned with the slot 211, and the neck portion 402 can slide in the continuous groove formed by the slot 211 and the through groove 212, so that the rotating seat 10 can rotate relative to the mounting seat 20, thereby realizing the angle adjustment of the desktop panel 60. After the angle adjustment of the desktop panel 60 is completed, the locking member 40 is moved laterally, and the locking portion 401 is inserted into the slot 211 and cooperates with the slot 211 to realize the limitation of the rotational freedom of the rotating seat 10 relative to the mounting seat 20. The downward pressure on the desktop panel 60 is transmitted to the locking member 40 via the rotating seat 10, and the locking member 40 is used to provide stable support for the rotating seat 10 to prevent the desktop panel 60 from abnormally flipping downward when under pressure.

[0031] The locking piece 40 is configured to be a rod with a circular cross-section, that is, the locking piece 40 is a slender cylindrical rod-shaped structure, and the locking portion 401 and the neck portion 402 are both formed by the outer peripheral surface structure of the locking piece 40, the diameter of the locking portion 401 is R1, the diameter of the neck portion 402 is R2, and the width of the through groove 212 is D, wherein R1>D>R2, so that the through groove 212 can allow the neck portion 402 to penetrate, so that the neck portion 402 can slide between two adjacent slots 211, and the locking portion 401 cannot slide from the slot 211 into the through groove 212. In a preferred embodiment, an annular groove 42 is provided on the outer circumference of the locking member 40, and a neck portion 402 is formed by the bottom surface of the groove 42. The portion of the locking member 40 not provided with the groove 42 forms the locking portion 401, and in particular, the portion of the locking member 40 located on the side of the groove 42 forms the locking portion 401. In other embodiments, a flange may be provided on the outer circumference of the locking member 40, and the diameter of the flange portion is relatively large to form the locking portion 401, and the portion of the locking member 40 located on the side of the flange forms the neck portion 402. In order to make the locking portion 401 better combined with the slot 211 and to reduce the matching clearance between the two as much as possible, so as to prevent the desktop panel 60 from shaking as much as possible, the utility model sets the slot 211 to be circular, and the diameter of the slot 211 is greater than or equal to the above R1. When the processing accuracy allows, the diameter difference between the slot 211 and the locking portion 401 is as small as possible to reduce the matching clearance between the locking portion 401 and the slot 211. In other embodiments, the cross-section of the locking member 40 is not limited to being circular. For example, the locking member 40 may be a rod-shaped member with a square cross-section. The shape of the slot 211 is set to be consistent with the cross-sectional shape of the locking member 40, so that when the locking portion 401 is located inside the slot 211, it can limit the rotational freedom of the rotating seat 10 relative to the mounting seat 20.

[0032] In another preferred embodiment, the utility model further includes a spring 50. The spring 50 is used to apply an elastic stress to the locking member 40, so that the locking member 40 always maintains a tendency to move towards the first position through this elastic stress. When no external force acts, the locking member 40 always remains in the first position in the left-right direction, that is, the locking portion 401 on the locking member 40 always remains in a position inside one of the card slots 211, and then the rotating seat 10 always remains in a state fixed relative to the mounting seat 20, so that the adjustment structure of the utility model can stably support the table top 60, and further prevent the table top 60 from abnormally turning downwards during use. In other embodiments, the spring 50 can also be replaced by other elastic members, such as a tension spring, an elastic rubber block, etc.

[0033] The rotating seat 10 includes a top wall 11 and two side walls 12. The top wall 11 abuts against the lower surface of the table top 60 and is connected to the table top 60. The two side walls 12 are respectively formed by bending downwards from the left and right sides of the top wall 11. The mounting seat 20 is placed between the two side walls 12. The spring 50 is sleeved on the locking member 40, with one end abutting against the mounting seat 20 and the other end abutting against the middle of the locking member 40. One end of the locking member 40 is fixedly connected with a snap ring 41, and a limiting flange located outside one of the side walls 12 is formed by using the snap ring 41. The other end of the locking member 40 forms a pressing end 43. When it is necessary to adjust the turning angle of the table top 60, the user pushes the pressing end 43 to make the locking member 40 move horizontally in the left-right direction, and then the locking member 40 moves from the first position to the second position.

[0034] A notch 13 is respectively formed on both side walls 12, and a supporting surface 131 is formed on the top surface of the notch 13. The mounting base 20 includes an embedding portion 201 disposed between the two side walls 12 and a fixing portion 202. The fixing portion 202 is fixedly connected to the top of the base 70. The width of the fixing portion 202 is greater than that of the embedding portion 201, so that both sides of the fixing portion 202 protrude from both sides of the embedding portion 201 respectively. When the table top 60 is in a horizontal state, the top surface of the fixing portion 202 abuts against the supporting surface 131 and is supported below the supporting surface 131, so that the table top 60 has good stability when in the horizontal state. And the supporting surface 131 cooperates with the top surface of the fixing portion 202 to remind the user that the table top 60 has been adjusted to the lowest angle. The embedding portion 201 includes two opposite side plates 21. The two side plates 21 are respectively located inside the two side walls 12. A plurality of card slots 211 and through slots 212 are provided on both side plates 21, that is, each side plate 21 is provided with a groove extending along an arc track and composed of a plurality of card slots 211 and a plurality of through slots 212. The locking member 40 passes through the grooves on the two side walls 12 and the two side plates 21. Two of the above-mentioned grooves 42 are provided on the locking member 40 to form two locking portions 401 and two necking portions 402 on the locking member 40; the locking member 40, the mounting base 20 and the rotating base 10 are all metal parts. See Figure 3 As shown, under the elastic stress of the spring 50, the locking member 40 is in the first position. The two locking portions 401 on the locking member 40 are respectively clamped in the card slots 211 at corresponding positions on the two side plates 21, and the degree of freedom of rotation of the rotating base 10 relative to the mounting base 20 is limited by the locking member 40; As Figure 4 shown, when the angle of the table top 60 needs to be adjusted, press the locking member 40 to make the locking member 40 horizontally move to the second position in the left-right direction. The two locking portions 401 are respectively staggered from the two side plates 21 in the left-right direction, so that the two grooves 42 are aligned with the two side plates 21 in the left-right direction. Rotate the table top 60, and the necking portion 402 formed by the grooves 42 can slide freely in the groove extending along the arc track, and adjust the table top 60 to the state as Figure 5 shown. Release the pressing external force on the locking member 40, and the spring 50 pushes the locking member 40 to the first position through elastic stress. After the locking member 40 horizontally moves, the locking portion 401 is clamped into the card slot 211 at the corresponding position, locking the rotating base 10 and the mounting base 20, so that the table top 60 maintains a fixed posture after the angle adjustment is in place.

[0035] It should be noted that in some other embodiments, the cooperation relationship between the above-mentioned spring 50 and the mounting seat 20, the rotating seat 10, and the locking member 40 can be changed, and the user can move the locking member 40 from the first position to the second position by pulling the locking member 40 in the left-right direction; in addition, in the present utility model, the card slot 211 and the through slot 212 can also be provided on the rotating seat 10, and the locking member 40 is passed through the mounting seat 20. For example, the card slot 211 and the through slot 212 are provided on the side wall 12 of the rotating seat 10, and the locking member 40 moves between the first position and the second position relative to the mounting seat 20 in the left-right direction.
