[0030] Reference Figure 1 As shown, the utility model provides a technical solution: an efficient pressure controller, comprising a pressure controller body 1, the side wall of the pressure controller body 1 is electrically connected to a wire 2, a hexagonal prism 3 is fixedly installed on the lower surface of the pressure controller body 1, the lower end of the hexagonal prism 3 is fixedly connected to a threaded tube 4, a replacement structure 5 is provided on the outside of the threaded tube 4, and a protective structure 6 is provided on the side wall of the pressure controller body 1.

[0031] The specific settings and functions of the replacement structure 5 and the protective structure 6 are described in detail below.

[0032] Reference Figure 1-Figure 5 As shown, in this embodiment, the replacement structure 5 includes a fixed ring 509 fixedly connected to the outside of the threaded tube 4. The outside of the threaded tube 4 is covered with a silicone ring 501. The silicone ring 501 is an unclosed circular ring structure. The end side of the silicone ring 501 is provided with a groove 508, and the other end of the silicone ring 501 is provided with a protrusion. The size of the protrusion is compatible with the size of the groove 508. By providing the groove 508 and protrusion on the silicone ring 501, the tightness of the silicone ring 501 after forming a circular ring structure is improved. Two sliding rods 503 are slidably connected to the inside of the hexagonal prism 3. The lower ends of the two sliding rods 503 are fixedly connected to the limit ring 502, which is located on the outside of the fixed ring 509. The limit ring 502 is sleeved on the outside of the silicone ring 501. At this time, when the threaded tube 4 and the screw are twisted again, the limit ring 502 can prevent the silicone ring 501 from becoming loose.

[0033] The side wall of the limiting ring 502 is fixedly connected with a spring piece 511, and the side wall of the hexagonal prism 3 is fixedly connected with a rectangular block 510. The spring piece 511 will be supported on the surface of the rectangular block 510 and bounce off. At this time, the limiting ring 502 will be sleeved on the outside of the silicone ring 501. The side wall of the limiting ring 502 is fixedly connected with a connecting block 504, and the side wall of the connecting block 504 is fixedly connected with a rotating pin 505. The upper end of the rotating pin 505 is rotatably connected with a clamping plate 506. The provision of the clamping plate 506 facilitates the lifting and manipulation of the limiting ring 502. The side wall of the hexagonal prism 3 is provided with a clamping groove 507. By rotating the clamping plate 506 on the rotating pin 505 and sleeved the clamping plate 506 on the inner side of the clamping groove 507, the limiting ring 502 can be temporarily fixed after lifting.

[0034] Reference Figure 1-Figure 2 and Figure 6 As shown, specifically, the protective structure 6 includes a fixed pin 62 fixedly connected to the outside of the pressure controller body 1, a telescopic rod 64 fixedly connected to the end side of the fixed pin 62, the other end of the telescopic rod 64 fixedly connected to the connecting strip 63, and the side wall of the connecting strip 63 fixedly connected to the protective ring 61, which is located on the outside of the wire 2. The telescopic rod 64 telescopes between the fixed pin 62 and the protective ring 61, which serves to limit the movement direction of the protective ring 61. A spring 65 is sleeved on the surface of the telescopic rod 64, and the two ends of the spring 65 are fixedly connected to the fixed pin 62 and the connecting strip 63 respectively. The protective ring 61 is buffered by the elastic force of the spring 65 between the fixed pin 62 and the connecting strip 63.

[0035] Working principle: when it is necessary to replace the silicone ring 501 on the pressure controller body 1, first pull the limit ring 502 to cover the outside of the fixing ring 509. When the card plate 506 moves to the same horizontal line as the card slot 507, rotate the card plate 506 on the rotating pin 505 and cover the card plate 506 on the inner side of the card slot 507. This can achieve temporary fixation of the limit ring 502 after lifting. At this time, the staff only needs to slightly rotate the threaded tube 4 and the screw mouth to easily remove the silicone ring 501 that is not a closed circular ring structure, and then take out a new silicone ring 501 that is not a closed circular ring structure, and cover the silicone ring 501 on the outside of the threaded tube 4. By setting the groove 508 and the protrusion on the silicone ring 501, the tightness of the silicone ring 501 after forming a circular structure is improved. The card plate 506 located on the inner side of the card slot 507 can be rotated out, and the spring piece 511 will be supported on the surface of the rectangular block 510 and bounce open. At this time, the limiting ring 502 will be sleeved on the outside of the silicone ring 501. At this time, the threaded tube 4 and the screw mouth are twisted again. The limiting ring 502 can prevent the silicone ring 501 from becoming loose, thereby realizing the replacement of the silicone ring 501. The silicone ring 501 fills the position between the limiting ring 502 and the fixing ring 509 and the screw mouth, which improves the performance of the silicone ring 501. By setting the replacement structure 5, it is convenient to quickly replace the silicone ring 501 on the pressure controller body 1 without completely opening the threaded tube 4, and it is convenient to regularly and quickly replace the aging silicone ring 501, which improves the replacement efficiency of the silicone ring 501 to a certain extent.

[0036] When the position of the wire 2 is pulled by external force, the protective ring 61 will be buffered by the elastic force of the spring 65 between the fixing pin 62 and the connecting strip 63, thereby avoiding the phenomenon that the connection position between the wire 2 and the pressure controller body 1 is seriously damaged due to long-term external force. The telescopic rod 64 is telescopic between the fixing pin 62 and the protective ring 61, which plays a role in limiting the moving direction of the protective ring 61, and the limited direction of the elastic force of the spring 65 further improves the protection effect of the wire 2. By setting the protective structure 6, the protection effect of the connection position between the pressure controller body 1 and the wire 2 is facilitated, and the service life of the pressure controller body 1 is extended to a certain extent.
