[0030] In this embodiment, the rotating mounting rod 5 rotates around the mounting control panel 1, and the rotating handle 9 is located in front of the rotating mounting rod 5 and arranged concentrically therewith. The rotation of the rotating mounting rod 5 is utilized to realize the position switching of the three mounting frames 11, thereby switching the rotor boxes 12 of different models.

[0031] In this embodiment, the flow connecting pipe 21 is located above the mounting frame 11 , and the three mounting frames 11 are arranged in a triangle around the center of the mounting collar 10 . The three rotor boxes 12 are of different models, and the three mounting frames 11 are installed with three models of rotor boxes 12 .

[0032] In this embodiment, the rotating drive rod 7 is inserted into the rotating installation rod 5 and movably connected and passes through the limiting slot 6. The limiting block 8 is located in the limiting slot 6. When the rotating drive rod 7 rotates, it drives the limiting block 8 to rotate and move in the limiting slot 6. When the rotating drive rod 7 rotates, it first rotates around the rotating installation rod 5, and then the limiting block 8 fits the side wall of the limiting slot 6 and drives the rotating installation rod 5 to rotate, thereby realizing segmented rotation.

[0033] In this embodiment, the plug structure 14 includes a top ring 15, a bottom ring 16, a signal plug 17, a lifting column 18, a reset spring 19 and a separation rope 20. The top ring 15 and the bottom ring 16 are both fixedly mounted on the front end of the signal transmission box 13, and the top ring 15 is located above the bottom ring 16. The signal plug 17 is movably mounted on the inner side of the top ring 15, the lifting column 18 is fixedly mounted on the lower end of the signal plug 17, the reset spring 19 is sleeved on the outer side of the lifting column 18, and the separation rope 20 is fixedly mounted on the lower end of the lifting column 18. The top ring 15 and the bottom ring 16 have the effect of movably mounting the signal plug 17 and the lifting column 18.

[0034] In this embodiment, the signal plug 17 is located below the flow display 2 and is connected to the docking socket 4. The signal plug 17 is lifted and lowered around the top ring 15.

The lower end of the reset spring 19 is pressed against the top of the bottom ring 16, and the upper end of the reset spring 19 is pressed against the bottom of the signal plug 17. One end of the separation rope 20 away from the lifting column 18 is wrapped around the outside of the rotating drive rod 7. When the separation rope 20 is pulled down, the signal plug 17 and the lifting column 18 are pulled down and the reset spring 19 is squeezed to contract. After the separation rope 20 is released, the reset spring 19 resets and drives the signal plug 17 and the lifting column 18 to rise.

[0035] In this embodiment, the end portion of the flow connecting pipe 21 is configured in a conical shape, and the flow connecting pipe 21 is connected to the inside of the rotor box 12 through the signal transmission box 13 .

[0036] In this embodiment, the front end of the mounting control panel 1 is located below the toggle knob 22 and fixedly mounted on a limit column 24 . The limit column 24 is located on one side of the toggle plate 23 . The cylindrical protrusion in front of the limit column 24 serves to position the toggle plate 23 .

[0037] In this embodiment, the joint structure 25 includes a movable ring 26, a movable tube 27, a docking joint 28, a docking spring 29 and a pipe joint 30. The movable ring 26 is fixedly installed at the front end of the mounting control panel 1, the movable tube 27 is movably installed on the inner side of the movable ring 26, the docking joint 28 is fixedly installed at one end of the movable tube 27, the pipe joint 30 is fixedly installed at the other end of the movable tube 27, and the docking spring 29 is sleeved on the outer side of the movable tube 27. The movable ring 26 plays the effect of movably installing the movable tube 27.

[0038] In this embodiment, the toggle plate 23 is sleeved on the outside of the movable tube 27 and pressed against one end of the pipe joint 30, one end of the docking spring 29 presses against one side of the movable collar 26, and the other end of the docking spring 29 presses against one end of the docking joint 28. The interior of the docking joint 28 is conically arranged, and the docking joint 28 is cooperatively connected with the flow docking tube 21. The toggle plate 23 pushes the pipe joint 30 and the movable tube 27 to move to one side, and the docking spring 29 contracts. When the toggle plate 23 is released, the docking spring 29 rebounds and drives the movable tube 27 to reset. The docking joint 28 is adapted to the flow docking tube 21 through the conical setting, so that the docking joint 28 and the flow docking tube 21 can be sealed and connected after being fitted.

[0039] It should be noted that the present invention is a liquid medicine filling flow meter. When in use, the mounting control panel 1 is installed on the liquid medicine filling machine, and the delivery pipe of the filling machine is cut off in the middle and connected to two pipe joints 30, so that the filled liquid medicine enters from the pipe joint 30 on one side, and then the liquid medicine passes through the movable pipe 27, the docking joint 28 and the flow docking pipe 21 to enter the signal transmission box 13, and the moving liquid medicine pushes the rotor in the rotor box 12 to rotate. After the rotor in the rotor box 12 rotates, the numerical signal of the rotation is counted according to the magnetic contact principle, so as to correspond to the flow of the liquid medicine passing through. The numerical signal is transmitted to the flow display 2 through the connection between the signal plug 17 and the docking socket 4, and is displayed through the control panel 3 in front of the flow display 2. Finally, the liquid medicine is hit from the flow docking pipe 21, the docking joint 28 and the movable pipe 27 on the other side to the pipe joint 30, so that the liquid medicine re-enters the filling pipe for filling processing, so as to complete the flow calculation when the liquid medicine is filled;

[0040] Through the integrated installation of the installation frame 11, three installation frames 11 are installed on the installation collar 10, and the three installation frames 11 are used to install three different types of rotor boxes 12. The rotors of different types of rotor boxes 12 have different sizes inside, and are used for flow calculation corresponding to different flow rates and concentrations of liquid medicines, so that the three types of rotor boxes 12 are integrated on the flow meter for selection and installation;

[0041] By grasping the toggle knob 22 and rotating it, the toggle plate 23 below the toggle knob 22 moves to one side, so that the toggle plate 23 pushes the pipe joint 30 and the movable pipe 27 to move to one side, driving the docking joint 28 to be quickly separated from the flow docking pipe 21, so as to quickly disconnect the filling pipe connection of the single rotor box 12 and the signal transmission box 13, and the toggle plate 23 is positioned by the limit column 24 to maintain the disconnected state. When the docking joint 28 and the flow docking pipe 21 need to be connected again, the toggle knob 22 and the toggle plate 23 are moved in the opposite direction to release the positioning of the toggle plate 23, and then the docking spring 29 pushes the docking joint 28 to quickly return to the original position through rebound, so that the docking joint 28 and the flow docking pipe 21 are quickly docked;

[0042] Grasp the rotating handle 9 and rotate it. The rotating handle 9 drives the rotating drive rod 7 to rotate and first reel in the separation rope 20 to pull the separation rope 20 downward, thereby pulling the lifting column 18 and the signal plug 17 downward, so that the signal plug 17 is separated from the docking socket 4. Then continue to rotate the rotating handle 9 to drive the rotating drive rod 7 to continue to rotate so that the limit block 8 is pressed against the side wall of the limit slot 6 in the rotating installation rod 5, thereby pushing the rotating installation rod 5 to rotate, and then use the connection of the mounting collar 10 to drive the three mounting frames 11 to rotate, and switch the signal transmission box 13 and the rotor box 12. When the rotating handle 9 is released after switching, the reset spring 19 rebounds and drives the signal plug 17 to rise, so that the signal plug 17 on the switched signal transmission box 13 is connected to the docking socket 4, and the signal transmission between the signal transmission box 13 and the flow display 2 is established.
