The table body 71 is provided with a circular mounting hole 73. The mechanism includes a T-shaped base 1 inserted in the circular mounting hole 73. A connecting hole 11 is vertically opened on the T-shaped base 1. A movable bolt 2 is inserted in the connecting hole 11. A spline structure 4 for lateral positioning and rotation limiting is provided between the movable bolt 2 and the connecting hole 11.

[0048] Specifically, the utility model is used for leveling the billiard table top 72, which is arranged between the panel 72 and the table body 71, and a circular mounting hole 73 is arranged on the table body 71, and the circular mounting hole 73 is a countersunk hole. The cylindrical portion 16 of the T-shaped base 1 is inserted into the circular mounting hole 73 for installation and positioning. The horizontal portion 17 of the T-shaped base 1 is against the surface of the table body 71 outside the mounting hole and is supported vertically upward. The T-shaped base 1 is provided with a connecting hole 11, and a movable bolt 2 is inserted in the hole. The movable bolt 2 can slide and rise axially in the hole. The threaded section 23 of the movable bolt 2 is meshed with an adjusting nut 3. The adjusting nut 3 is located between the T-shaped base 1 and the head 21 of the movable bolt 2, and is provided with an upward supporting force by the T-shaped base 1. The panel 72 is placed On the head 21 of the movable bolt 2, in this mechanism, due to the support of the T-shaped base 1, the vertical position of the adjusting nut 3 remains unchanged, and with the rotation of the adjusting nut 3, the meshing position of the adjusting nut 3 on the movable bolt 2 changes up and down, that is, the height of the movable bolt 2 relative to the adjusting nut 3 changes, thereby achieving the effect of adjusting the height of the adjustment panel 72. In particular, a spline structure 4 is provided between the movable bolt 2 and the connecting hole 11. On the one hand, since the size of the spline structure 4 is just right for clamping, the movable bolt 2 is positioned laterally to reduce unnecessary horizontal shaking and stabilize the desktop. On the other hand, a rotatable limiter can be used to limit the rotation of the movable bolt 2 relative to the T-shaped base 1, thereby preventing the movable bolt 2 from rotating with the adjusting nut 3 when the adjusting nut 3 is rotated, thereby facilitating adjustment.

[0049] like Figure 2A , 4As shown in Figures 5 and 6, the movable bolt 2 includes a head 21 and a rod body 22. The rod body 22 includes a threaded section 23 and a positioning section 24.

The connecting hole 11 includes a yielding section 12 and a spline section 13. The yielding section 12 is located above the spline section 13, and the inner diameter of the yielding section 12 is larger than the inner diameter of the spline section 13. The spline section 13 is provided with a spline 41 protruding toward the axis.

[0050] Specifically, the rod body 22 is divided into a threaded section 23 and a positioning section 24 from top to bottom. The threaded section 23 is provided with an external thread for meshing with the adjusting nut 3. A spline structure 4 is provided between the positioning section 24 and the connecting hole 11 for lateral positioning and rotation limiting. The spline structure 4 achieves a predetermined effect by clamping the spline 41 in the spline groove 42, wherein the size and number of the spline 41 and the spline groove 42 are adapted to each other, and the offset after docking is very small, which has a good positioning and anti-shaking effect. The spline 41 is arranged in the connecting hole 11, protruding toward the axis, and the spline groove 42 is arranged on the positioning section 24. Of course, the names of the spline 41 and the spline groove 42 here are relative, and it can also be understood that the protrusion between the spline grooves 42 is the spline 41, and the groove between the spline 41 is the spline groove 42. The inner diameter of the making way section 12 is larger than the spline section 13, that is, it is also larger than the outer diameter of the positioning section 24 of the rod body 22, and is used to make way for the spline structure 4 on the positioning section 24 of the rod body 22, ensuring that the rod body 22 can smoothly pass through the making way section 12 and cooperate with the spline section 13. The spline section 13 is provided with a spline 41.

[0051] In this embodiment, the adjusting nut 3 is a flange nut, and a circular groove 14 is provided at the upper end of the T-shaped base 1. The circular groove 14 is coaxial with the connecting hole 11. The outer diameter of the flange portion 31 of the flange nut is adapted to the inner diameter of the circular groove 14, and the flange portion 31 is clamped in the circular groove 14.

[0052] Specifically, the adjusting nut 3 is a flange nut, which includes a hexagonal portion and a flange portion 31. A circular groove 14 is provided on the T-shaped base 1. The flange portion 31 is just clamped in the circular groove 14 to form a rotating connection, thereby achieving a positioning effect and reducing the swing of the upper section of the movable bolt 2. At the same time, the concave setting reduces the height of the flange nut and increases the vertical range of motion of the movable bolt 2.

[0053] In this embodiment, an elastic washer 5 is provided between the head 21 of the movable bolt 2 and the panel 72, a fixing countersunk hole 51 is axially provided on the elastic washer 5, a rivet hole 52 is opened at the upper end of the head 21, a rivet 53 is inserted into the fixing countersunk hole 51, and the inner end of the rivet 53 is riveted and fixed to the rivet hole 52.

[0054] Specifically, an elastic washer 5 is provided between the movable bolt 2 and the panel 72 for buffering.

[0055] As an optimization, two base fixing holes 18 are axially penetrated on the horizontal straight portion 17 of the T-shaped base 1 for bolt connection with the table body 71. The base fixing holes 18 are countersunk holes or through holes. The horizontal straight portion 17 is provided with base fixing holes 18, and bolts are passed through the fixing holes to achieve fixed connection with the table body 71.

An anti-slip screw 62 is threaded in the anti-slip screw hole 61, and an anti-slip washer 63 is sleeved on the anti-slip screw 62. The outer diameter of the anti-slip washer 63 is larger than the inner diameter of the connecting hole 11.

[0057] Specifically, the connecting hole 11 is set through the T-shaped base 1, that is, the lower end of the connecting hole 11 is also open, and the movable bolt 2 can pass through the lower end. An anti-slip screw hole 61 is provided at the bottom of the anti-slip screw hole 61, and an anti-slip screw 62 is screwed on the screw hole. An anti-slip washer 63 is sleeved on the anti-slip screw 62. As the adjusting nut 3 is rotated and adjusted, before the movable bolt 2 rises too high and cannot ensure the lateral stability and connection strength, the anti-slip washer 63 is abutted against the lower end of the T-shaped base 1, limiting the continued rise of the movable bolt 2, thereby maintaining stability and preventing it from falling out. Moreover, the anti-slip screw 62 and the anti-slip screw hole 61 are detachably connected, which is convenient for disassembly and assembly.

[0058] Specific working principle: When in use, the movable bolt 2 can be adjusted by rotating the adjusting nut 3 to adjust the height of the head 21. Under the calibration of the level meter, the adjusting nut 3 at the corresponding position can be adjusted to adjust the overall level of the panel 72, which is convenient for adjustment. Moreover, during adjustment, if the movable bolt 2 rises too far, the anti-slip washer 63 will abut against the lower end of the T-shaped base 1 to prevent the bolt from continuing to rise and fall out, thereby ensuring stability.

[0059] Example 2

[0060] The specific working principle of this embodiment is basically the same as that of Embodiment 1, and the difference lies in the positioning structure between the flange nut and the T-shaped base 1.
