DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 7In an embodiment of the present invention, a calibration mechanism for assembling a medical pump head based on multiple calibrations to prevent deviation is provided, which is used to assemble the bottle cap and the pressing head of the medical pump head. The mechanism comprises a frame 10 and a fixing mechanism 30. A movable frame 11 and a fixed frame 12 are provided inside the frame 10. The movable frame 11 is slidably mounted on the frame 10, and the fixed frame 12 is fixedly mounted on the frame 10. The fixed frame 12 is located below the movable frame 11. The fixing mechanism 30 is installed on both the movable frame 11 and the fixed frame 12. The fixing mechanism 30 on the movable frame 11 is used to fix the pressing head, and the fixing mechanism 30 on the fixed frame 12 is used to fix the bottle cap. When the movable frame 11 is oriented toward the fixed frame When 12 moves, the pressing head and the bottle cap are docked and assembled; the fixing mechanism 30 includes a rotatably arranged fixing seat 31 and a positioning seat 32, the fixing seat 31 and the positioning seat 32 are fixedly connected, and a receiving groove is provided at the center of the positioning seat 32, and the receiving groove is used to place the pressing head or the bottle cap, and a plurality of slide grooves are symmetrically provided on the positioning seat 32, and a slider 37 is slidably installed on the slide groove, and an elastic telescopic rod 38 is installed on the side of the slider 37 facing the receiving groove, and the telescopic end of the elastic telescopic rod 38 is connected to a positioning plate. After the pressing head or the bottle cap is placed inside the receiving groove, the elastic telescopic rod 38 adaptively adjusts its length so that the positioning plate squeezes the pressing head or the bottle cap, thereby fixing the pressing head or the bottle cap;

[0024] In the embodiment of the present application, a turntable 35 is rotatably mounted on the bottom of the positioning seat 32, and a first gear ring 33 is rotatably mounted on the fixed seat 31. The first gear ring 33 is fixedly connected to the turntable 35, and the turntable 35 is rotatably connected to one end of the connecting rod 36, and the other end of the connecting rod 36 is rotatably connected to the bottom of the slider 37. When the first gear ring 33 is in a rotating state, it drives the turntable 35 to rotate, and the turntable 35 drives the slider 37 to move along the slide groove through the connecting rod 36, so that the length of the elastic telescopic rod 38 changes. It can be understood that in this embodiment, when multiple elastic telescopic rods 38 change their lengths at the same time, they have the same telescopic amount, and the slider 37 squeezes the pressing head or bottle cap so that the pressing head or bottle cap is in the center of the receiving groove; in addition, Figure 5 As shown, the fixing mechanism 30 further includes a guard plate 39 , the upper side of which is fixedly connected to the positioning seat 32 , and the guard plate 39 is used to protect the turntable 35 and the connecting rod 36 .

[0025] Furthermore, in the embodiment of the present application, a spiral sleeve 16 is fixedly installed at the bottom of the movable frame 11, and a rotating shaft 17 is rotatably installed on the fixed frame 12, and a driving gear 20 is fixedly installed on the rotating shaft 17, and the driving gear 20 is meshed with the first gear ring 33 of the fixing mechanism 30; the upper end of the rotating shaft 17 is provided with a thread that cooperates with the spiral sleeve 16. When the movable frame 11 moves toward the fixed frame 12, the spiral sleeve 16 moves downward along the rotating shaft 17. During the movement of the spiral sleeve 16, the rotating shaft 17 rotates, thereby driving the driving gear 20 to rotate. It can be understood that during the rotation of the driving gear 20, the first gear rings 33 of the upper and lower fixing mechanisms 30 are simultaneously driven to rotate, so that the upper and lower fixing mechanisms 30 simultaneously position the pressing head and the bottle cap, ensuring that the pressing head or the bottle cap are on the same axis, avoiding deviation in the position of the pressing head and the bottle cap during assembly of the pump head, and ensuring the accuracy of assembly of the pressing head and the bottle cap. In addition, in the embodiment of the present application, a hydraulic rod 15 is fixedly installed on the top of the frame 10, and the telescopic end of the hydraulic rod 15 is connected to the mobile frame 11. The hydraulic rod 15 is used to control the up and down movement of the mobile frame 11.

[0026] Please refer again Figure 1-Figure 4 In the embodiment of the present application, the fixing seat 31 is fixedly mounted with a second ring gear 34, and the movable frame 11 and the fixed frame 12 are both rotatably mounted with an adjusting gear 14, and the adjusting gear 14 is engaged with the second ring gear 34. When the adjusting gear 14 is in a rotating state, the adjusting gear 14 drives the second ring gear 34 to rotate, thereby driving the fixing mechanism 30 to rotate as a whole, and then causing the pressing head and the bottle cap to rotate, thereby realizing the rotational position adjustment of the pressing head and the bottle cap, and ensuring that the pressing head and the bottle cap are at a suitable alignment angle.

[0027] Furthermore, in the embodiment of the present application, a limiting rod 13 is fixedly installed on the side of the frame 10, and a limiting groove with the same cross-sectional shape as the limiting rod 13 is provided on the adjusting gear 14. When the mobile frame 11 moves toward the fixed frame 12, the limiting rod 13 is inserted into the limiting groove of the adjusting gear 14 to limit the adjusting gear 14, thereby preventing the adjusting gear 14 from rotating during the assembly process of the pressing head and the bottle cap, thereby ensuring the accuracy of the assembly of the pressing head and the bottle cap. In addition, an adjusting knob 141 for controlling the rotation of the adjusting gear 14 is provided on both the mobile frame 11 and the fixed frame 12. Before the mobile frame 11 moves, the adjusting knob 141 is used to control the rotation of the adjusting gear 14 to adjust the rotational position of the pressing head and the bottle cap.
