[0026] To further understand the utility model's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] Example:

[0028] Please see Figure 1 - Figure 8A ball valve diameter measuring device includes a measuring plate 1, a housing 2 threaded onto one side of the measuring plate 1, and a base 3 threaded onto the end of the housing 2. A connecting rod 8 is rotatably connected to the middle of the base 3, and a rotating block 6 is welded to the end of the connecting rod 8. A rotating groove 7 welded to the middle of the base 3 is fitted on the surface of the rotating block 6. A first gear 5 and a second gear 9 are sequentially welded from bottom to top on the surface of the connecting rod 8. A fourth gear 31 meshes with the surface of the first gear 5, and a rotating rod 30 passing through one side of the housing 2 is welded to the middle of the fourth gear 31. A turntable 29 is welded to the end of the base 3. Several sets of third teeth mesh around the second gear 9. The wheel 12, and the third gear 12, has a bolt 14 welded to the middle of the housing 2, and the bolt 14 is rotatably connected to the base 3. A second traction ring 16 is fitted on both ends of the bolt 14, and a support frame 4 is welded to the surface of each second traction ring 16. The ends of the support frames 4 are threaded onto the base 3. A threaded sleeve 21 is threaded onto the surface of the bolt 14, and a separation component is provided on the surface of each threaded sleeve 21. A slider 17 is welded to the end of each separation component. A groove 11 is provided on the surface of each slider 17 around the base 3, and a limiting rod 13 passing through the groove 11 is welded to the surface of each slider 17. When operated… When the author needs to measure the ball of the ball valve, the operator first places the ball on the measuring plate 1, then rotates the turntable 29. The turntable 29 drives the rotating rod 30 to rotate, so that the rotating rod 30 meshes with the first gear 5. When the fourth gear 31 meshes with the first gear 5, the first gear 5 drives the connecting rod 8 to rotate, so that the connecting rod 8 drives the second gear 9 to rotate. The rotating second gear 9 meshes with the third gear 12. When the third gear 12 rotates, it drives the bolt 14 to rotate. When the bolt 14 rotates, the surface of the bolt 14... The threads on the threaded sleeve 21 and the threads on the threaded sleeve 21 engage with each other. The threaded sleeve 21 drives the second pull block 20 to move. The second pull block 20 drives the first pull block 18 to move through the positioning groove 19. The first pull block 18 drives the slider 17 to slide in the slide groove 11. When the slider 17 moves, it drives the limit rod 13 to move. The limit rod 13 slides around the measuring plate 1, clamping the limit rod 13 on the surface of the ball valve ball. The position of the limit rod 13 is aligned with the scale teeth etched on the surface of the base 3, thereby measuring the diameter of the ball valve ball and improving the convenience of measurement for the operator.

[0029] In other embodiments, each limiting rod 13 has a guide groove 27 in its middle, and a connecting block 26 is embedded in the middle of each guide groove 27. An extension plate 22, which is attached to the surface of the limiting rod 13, is symmetrically welded to both ends of the connecting block 26. Each connecting block 26 has a spring groove 25 in its middle, and a spring 24 and a button 23 are respectively disposed inside the spring groove 25. The two ends of the spring 24 abut against the inside of the spring groove 25 and the surface of the button 23, respectively. The ends of the buttons 23 all pass through one side of the guide groove 27. Each button 23 is cylindrical, and the side of the button 23 passing through the guide groove 27 is provided with a circular through hole that matches the button 23. When the operator needs to adjust the height of the extension plate 22 and the limiting rod 13, the operator first presses the button 23. The button 23 slides within the spring groove 25 under force. When the button 23 slides within the spring groove 25, the button 23 compresses the spring 24, causing the spring 24 to... After elastic deformation occurs, the spring 24 avoids the button 23, causing it to move out of the through hole on the surface of the guide groove 27 and into the spring groove 25. This removes the button 23 from fixing the connecting block 26 and the guide groove 27. The operator then moves the extension plate 22, causing the connecting block 26 to slide within the guide groove 27, increasing the length between the extension plate 22 and the limiting rod 13. The operator then releases the button 23, and the spring 24 recovers its elastic deformation, pushing the button 23 to insert into the through hole on the surface of the guide groove 27. This allows the operator to fix the connecting block 26 and the guide groove 27, thus fixing the positions of the extension plate 22 and the button 23. This facilitates the measurement of ball valve balls of different sizes, expanding the operator's usability.

[0030] In other embodiments, a second pull block 20 is welded to the side of the threaded sleeve 21 near the base 3, and a positioning groove 19 is opened in the middle of the second pull block 20. A first pull block 18 is inserted into the middle of the positioning groove 19, and the first pull block 18 is welded to the slider 17 through the slide groove 11. When the operator separates the measuring plate 1 from the outer shell 2, the operator pulls the measuring plate 1, the measuring plate 1 raises the slide groove 11 and drives the slider 17 to move. The slider 17 drives the first pull block 18 to move, so that the first pull block 18 moves out of the positioning groove 19. The first pull block 18 and the second pull block 20 are separated, which makes it convenient for the operator to open the upper part of the outer shell 2 when repairing or maintaining the gears inside the outer shell 2.

[0031] In other embodiments, a first traction ring 10 is symmetrically sleeved on the surface of the rotating rod 30, and a support plate 32 is welded to the surface of the first traction ring 10. The support plate 32 is welded to the inside of the outer shell 2, and a triangular plate 15 is welded between the outer shell 2 and the support plate 32. Several sets of first traction rings 10 sleeved on the surface of the rotating rod 30 are fixed at the end of the support plate 32, so that the first traction rings 10 pull the rotating rod 30, thereby increasing the stability of the rotating rod 30 when rotating.

[0032] In other embodiments, the rotating rod 30 is fitted with an extension tube 28 through one side of the outer casing 2, and the extension tube 28 is welded to the outer wall of the outer casing 2, which increases the friction between the rotating rod 30 and the extension tube 28 and improves the stability of the rotation of the rotating rod 30.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
