DETAILED DESCRIPTION
[0026] Reference Figure 1-4As shown, the utility model provides a technical solution: a movable fixing device for a diffusion pump, comprising an L-shaped frame 1, a fixed plate 2 is fixedly connected to the surface of the L-shaped frame 1, a servo motor 3 is fixedly connected to one side of the fixed plate 2, the output end of the servo motor 3 is fixedly connected to a threaded rod 4, a movable hole 5 is opened on the surface of the L-shaped frame 1, the inner surface of the movable hole 5 is slidably connected to a slide 6, the slide 6 is threadedly connected to the arc surface of the threaded rod 4, a round rod 7 is slidably inserted into the inner sliding portion of the slide 6, the arc surface of the round rod 7 is fixedly connected to a connecting frame 8, and one side of the connecting frame 8 is fixedly connected to a diffusion pump body 9. The effect of adjusting the height of the diffusion pump body 9 is achieved, which avoids the need for staff to maintain the diffusion pump. When the diffusion pump body 9 is used for a long time, it is necessary to replace internal parts, clean the pump body, etc. Since the diffusion pump body 9 is fixedly connected to the L-shaped frame 1 and the height cannot be adjusted, it makes it difficult for maintenance personnel to operate and increases the time and labor intensity of maintenance, thereby improving the convenience of the device. Two limit grooves 10 are provided on the inner surface of the movable hole 5, and the inner surface of the limit groove 10 is slidably connected to the limit rod 11, and one end of the two limit rods 11 is fixedly connected to the slide 6. The slide 6 drives the limiting rod 11 to slide on the inner surface of the limiting groove 10, preventing the slide 6 from rotating with the rotation of the threaded rod 4, making the path of the slide 6 more stable and improving the stability of the device. One end of the round rod 7 is fixedly connected to an elliptical plate 12, the surface of the elliptical plate 12 is provided with a mounting hole, the inner surface of the mounting hole of the elliptical plate 12 is fixedly connected to a short rod 13, the arc surface of the short rod 13 is rotatably connected to a clamping plate 14, and the surface of the slide 6 is fixedly connected to three U-shaped buckles 15. Pull the clamping plate 14 to rotate on the arc surface of the short rod 13 until the clamping plate 14 disengages from the inner surface of the U-shaped buckle 15, and rotate the diffusion pump body 9 to drive the round rod 7 to rotate within the slide 6, so that the staff can fine-tune the angle of the diffusion pump body 9 and facilitate accurate docking and fixing with the corresponding interface. The surface of the elliptical plate 12 is fixedly connected to a placement plate 20, and a rod 16 is slidably inserted in the placement plate 20. One end of the rod 16 is fixedly connected to a setting plate 17, and a slot is provided on one side of the clamping plate 14. Pull the card plate 14 to rotate on the arc surface of the short rod 13 until the card plate 14 rotates ninety degrees, push the setting plate 17 to drive the insertion rod 16 to slide in the placement plate 20, and insert it into the card slot of the card plate 14 to prevent the card plate 14 from sliding downward during the rotation of the diffusion pump body 9 by the staff, which affects the adjustment of the diffusion pump body 9. The arc surface of the short rod 13 is covered with two torsion springs 18, and the two ends of the torsion spring 18 are respectively fixedly connected to the inner surface of the mounting hole of the card plate 14 and the elliptical plate 12. The torsion of the torsion spring 18 drives the card plate 14 to rotate on the arc surface of the short rod 13, and the card plate 14 is tightly attached to the U-shaped buckle 15, which improves the stability of the card plate 14 limit. The arc surface of the insertion rod 16 is covered with a spring 19, and the two ends of the spring 19 are respectively fixedly connected to the placement plate 20 and the setting plate 17.The elastic force of spring 19 drives the insertion rod 16 to slide within the placement plate 20 and automatically insert into the slot of the card plate 14. Two locking plates 21 are fixedly connected to the surface of the slide 6. The size of the limit rod 11 is compatible with the size of the limit slot 10. Rotating the diffusion pump body 9 drives the connecting frame 8 to rotate until the connecting frame 8 contacts the locking plates 21, facilitating the alignment of the card plate 14 and the U-shaped buckle 15.
[0027] Working principle: when the staff needs to maintain the diffusion pump body 9, the height of the diffusion pump body 9 needs to be adjusted before maintenance. First, start the servo motor 3, the servo motor 3 drives the threaded rod 4 to rotate, the threaded rod 4 drives the slide 6 to move, the slide 6 drives the limit rod 11 to slide on the inner surface of the limit groove 10, the slide 6 drives the round rod 7 to move, the round rod 7 drives the connecting frame 8 to move, and the connecting frame 8 drives the diffusion pump body 9 to move until it is adjusted to the appropriate position. When the angle of the diffusion pump body 9 needs to be adjusted, the card plate 14 is pulled to rotate on the arc surface of the short rod 13 until the card plate 14 disengages from the inner surface of the U-shaped buckle 15, and the diffusion pump body 9 is rotated to drive the round rod 7 to rotate in the slide 6, so that the staff can fine-tune the angle of the diffusion pump body 9 and facilitate precise alignment with the corresponding interface. After fixing, rotate the diffusion pump body 9 to drive the connecting frame 8 to rotate until the connecting frame 8 contacts the locking plate 21, which facilitates the alignment of the card plate 14 and the U-shaped buckle 15, and pull the setting plate 17 to slide in the placement plate 20 until the insertion rod 16 is out of the card plate 14 slot. The torsion of the torsion spring 18 drives the card plate 14 to rotate on the arc surface of the short rod 13 and is stuck on the inner surface of the U-shaped buckle 15, thereby achieving the effect of adjusting the height of the diffusion pump body 9, avoiding the need for staff to maintain the diffusion pump. When the diffusion pump body 9 is used for a long time, it is necessary to replace internal parts, clean the pump body, etc. Since the diffusion pump body 9 is fixedly connected to the L-shaped frame 1 and the height cannot be adjusted, it is difficult for maintenance personnel to operate and increases the time and labor intensity of maintenance, thereby improving the convenience of the device.
