[0037] like Figure 1-Figure 9 As shown, in this embodiment, the turntable positioning device is used to position and coincide the center of the turntable 100 with the center of the round table 200, and the turntable positioning device includes a plurality of positioning mechanisms. Among them, along the circumferential direction of the turntable 100, the plurality of positioning mechanisms are arranged at intervals, and the positioning mechanism includes a ruler bar assembly 1 and a positioning assembly 2. The ruler bar assembly 1 includes a fixing frame 11, a ruler bar 12 and a first elastic member 13. The fixing frame 11 is arranged on the turntable 100, and the first elastic member 13 is arranged on the fixing frame 11. The first end of the ruler bar 12 is rolled up on the fixing frame 11 and connected to the first elastic member 13. The positioning assembly 2 includes a positioning member 21, a second elastic member 22 and a clamping member 23. The clamping member 23 is slidably arranged on the positioning member 21. The second end of the ruler bar 12 is arranged on the positioning member 21. The two ends of the second elastic member 22 are respectively connected to the positioning member 21 and the clamping member 23. Under the action of the second elastic member 22, the positioning member 21 and the clamping member 23 can be respectively pressed against the top surface and the bottom surface of the edge of the round table 200.

[0038] Specifically, there are four positioning mechanisms, and along the circumferential direction of the turntable 100, two adjacent positioning mechanisms are arranged at 90 degrees at the edge of the turntable 100. The first elastic member 13 is set as a tension spring or a torsion spring, which is used to reset the ruler 12. The fixing frame 11 is installed on both sides of the inner wall of the turntable 100. One end of the first elastic member 13 is connected to the fixing frame 11, and the other end is connected to the first end of the ruler 12. The ruler 12 is rolled up on the rotating shaft of the fixing frame 11, and the second end of the ruler 12 is connected to the positioning member 21. The second elastic member 22 is in a contracted state by default. The clamping member 23 is spliced ​​with the positioning member 21 under the elastic action of the second elastic member 22. The positioning assembly 2 can be close to the outer peripheral surface of the edge of the turntable 100 under the action of the ruler 12 and the first elastic member 13. The positioning assembly 2 is used to clamp the edge of the round table 200. The working process of the turntable positioning device is as follows: the positioning component 2 is initially close to the edge of the turntable 100. After the turntable 100 is placed approximately in the center of the round table 200, the positioning component 2 is pulled to the edge of the round table 200. At the same time, the ruler 12 is stretched, and then the clamping member 23 is pulled down. The second elastic member 22 is stretched, and the clamping member 23 is released after aligning with the edge of the round table 200. The positioning member 21 and the clamping member 23 are respectively pressed against the top and bottom surfaces of the edge of the round table 200 under the rebound action of the second elastic member 22, that is, the positioning component 2 clamps the edge of the round table 200. The remaining three positioning mechanisms also complete the above operation process synchronously, and then read the length values ​​of the ruler strips 12 on the four positioning mechanisms respectively, which is the shortest distance between the edge of the turntable 100 and the edge of the round table 200. Move the turntable 100 until the length values ​​of the ruler strips 12 of the four positioning mechanisms are the same, then it is judged that the center of the turntable 100 coincides with the center of the round table 200, and the positioning is accurate and there is no offset, ensuring that the dining area size of each customer sitting around the round table 200 is the same. When the round table 200 and the turntable 100 are positioned, pull down the clamping member 23 to remove the positioning component 2 from the edge of the round table 200 to avoid affecting the use of the turntable 100. Then the clamping member 23 is reunited with the positioning member 21 under the action of the second elastic member 22, and then the ruler strip 12 is slowly rolled up on the rotating shaft of the fixing frame 11 under the action of the first elastic member 13 until the positioning component 2 is close to the outer peripheral surface of the edge of the turntable 100, and the storage is completed, waiting for the next positioning and use of the turntable 100. Preferably, there are three positioning mechanisms, which are arranged on the turntable 100 at intervals of 120 degrees along the circumferential direction of the turntable 100. The three positioning mechanisms also follow the above-mentioned operation process, so that the center of the turntable 100 can be positioned and coincided with the center of the round table 200.

[0039] Further, refer to Figure 2 and Figure 6The ruler assembly 1 further includes a third elastic member 14 and a connecting piece 15. The third elastic member 14 is disposed between the second end of the ruler 12 and the positioning member 21.

Specifically, the third elastic member 14 is configured as a spring. The first end of the ruler 12 is connected to the first elastic member 13. The second end of the ruler 12 is connected to the connecting piece 15. One end of the third elastic member 14 is fixed to the positioning member 21, and the other end is fixed to the connecting piece 15. There are multiple third elastic members 14, and the multiple third elastic members 14 are distributed in a matrix. In the initial state, the positioning assembly 2 can be closely attached to the outer peripheral surface of the edge of the turntable 100 under the elastic action of the third elastic member 14. In the process of pulling out the positioning assembly 2, the third elastic member 14 drives the ruler 12 to be pulled out from the fixing frame 11, which plays a certain buffering role.

[0040] Further, refer to Figure 5 and Figure 6 The positioning member 21 is provided with a slide groove 211, the second elastic member 22 is located in the slide groove 211, and the clamping member 23 is located in the slide groove 211 and can slide along the length direction of the slide groove 211. Specifically, the slide groove 211 includes two side walls and a bottom wall connected between the two side walls, the clamping member 23 is slidably located between the two side walls, one end of the second elastic member 22 is connected to one end of the clamping member 23, and the other end of the second elastic member 22 is connected to the bottom wall, the second elastic member 22 is in a contracted state by default, the clamping member 23 is assembled with the positioning member 21 under the elastic action of the second elastic member 22, and the clamping member 23 and the second elastic member 22 are both hidden in the slide groove 211, which has good aesthetics and is not easy to touch the second elastic member 22 and affect its own elastic effect. The clamping member 23 is pulled, and part of the clamping member 23 slides out of the slide slot 211 , the second elastic member 22 is stretched, and under the action of the second elastic member 22 , the clamping member 23 and the positioning member 21 are clamped on the top and bottom surfaces of the edge of the round table 200 .

[0041] Further, continue to refer to Figure 5 and Figure 6The positioning member 21 is also provided with an avoidance groove 212, and a protrusion 3 is convexly provided at the other end of the clamping member 23. The clamping member 23 can slide relative to the positioning member 21 so that the protrusion 3 can be hidden in the avoidance groove 212 or the protrusion 3 is separated from the avoidance groove 212. Specifically, in the initial state, the clamping member 23 is assembled with the positioning member 21 under the elastic action of the second elastic member 22, and the protrusion is hidden in the avoidance groove 212, which has good aesthetics and plays a certain protective role on the protrusion. Pull the positioning assembly 2 to the edge of the round table 200, then pull down the clamping member 23, the second elastic member 22 is extended, the protrusion is separated from the avoidance groove 212, and the clamping member 23 is released after aligning with the edge of the round table 200. Under the action of the second elastic member 22, the positioning member 21 is pressed against the top surface of the edge of the round table 200, and the protrusion is pressed against the bottom surface inside the edge of the round table 200, so that the positioning assembly 2 is clamped and fixed to the round table 200.

The first end of the ruler 12 is arranged through the notch of the mounting groove 101 and is rolled up on the fixing frame 11, and the second end of the ruler 12 is connected to the connecting piece 15, and the ruler 12 is elongated or rolled up relative to the notch.

[0043] Further, refer to Figure 2 , scale marks are set on the ruler bar 12. Specifically, the scale marks are expressed in length, and the value of the scale marks on the ruler bar 12 on the positioning mechanism is read. The read scale mark is the shortest distance between the edge of the turntable 100 and the edge of the round table 200. The turntable 100 is moved until the scale marks of the ruler bars 12 read on the four positioning mechanisms are the same, then it is determined that the center of the turntable 100 coincides with the center of the round table 200, and accurate positioning is achieved.
