Technical Field
[0001] The utility model relates to the field of pressure controllers, in particular to a waterproof pressure controller. Background Art
[0002] A pressure controller is a device used to monitor and control the pressure in a fluid. It can detect the pressure of the fluid and automatically adjust or control the pressure of the fluid according to the set value. The sensor or pressure probe is inserted into the fluid to measure the pressure in the fluid. The sensor can convert the pressure signal into an electrical signal and transmit it to other parts of the controller for processing, thereby achieving the effect of regulating the pressure.
[0003] At present, when installing the pressure sensor, there is no prevention of moisture from invading the connection between the pressure sensor and the pipeline, which leads to rust at the connection between the pressure sensor and the pipeline, reducing the service life of the pipeline, and it is not easy to disassemble the pressure sensor after the pipeline is rusted; therefore, a waterproof pressure controller is proposed to address the above problems.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The following is combined with Figure 1-5 To further explain this application in detail,
[0025] The present application embodiment discloses a waterproof pressure controller. Figure 1 A waterproof pressure controller comprises a controller body 1; a connecting pipe 2 is fixedly installed at the bottom end of the controller body 1, an external connecting pipe 5 is sleeved on the surface of the bottom of the connecting pipe 2, a waterproof component 3 is arranged on the surface of the connecting pipe 2, and a stabilizing component 4 is arranged on the surface of the waterproof component 3;
[0026] Reference Figure 3-Figure 4 The waterproof component 3 includes two grooves 31 on the left and right sides of the bottom of the connecting pipe 2. The two grooves 31 are fixedly installed with fixed telescopic rods 32. The surface of the fixed telescopic rod 32 is rotatably connected with a push rod 33. The end of the push rod 33 away from the fixed telescopic rod 32 is rotatably connected with a sliding block 34. The end of the sliding block 34 away from the push rod 33 is fixedly installed with a buffer spring 35. The sliding block 34 is slidably connected to the inside of the groove 31. When the sliding block 34 is pushed, it will slide in the inside of the groove 31, so that the sliding block 34 can drive the buffer spring 35 to move horizontally. The end of the buffer spring 35 away from the sliding block 34 is fixedly connected with a lever 36. The lever 3 6 is rotatably connected to the inside of the groove 31, and the lever 36 is fixedly connected to the end surface of the lever 36 close to the inside of the groove 31. When one end of the sliding block 34 is pushed by the buffer spring 35, it will rotate. The bottom of the lever 36 is rotatably connected to a semicircular ring 37, and the end surfaces on both sides of the semicircular ring 37 are fixedly connected to the connecting telescopic rod 38. There are two semicircular rings 37 and they are symmetrically arranged on the left and right sides of the surface of the external pipe 5. The two ends of the connecting telescopic rod 38 are respectively fixedly connected to the end surfaces of the two semicircular rings 37. When the two semicircular rings 37 are pushed and then pulled by the telescopic rod 38 to approach or move away from each other, the moving trajectories of the two are the same and will not deviate.
[0027] Reference Figure 2 and Figure 5 The stabilizing component 4 includes a connecting rod 41 fixedly installed at the bottom end of the connecting pipe 2, and a tightening ring 42 is fixedly installed at the bottom end of the connecting rod 41. A vertical groove is opened on the surface of the bottom of the tightening ring 42, and the vertical grooves are evenly spaced on the surface of the tightening ring 42. The side of the tightening ring 42 with the vertical groove can be bent, so as to press and limit the external pipe 5 inside the tightening ring 42. A fixing block 43 is fixedly installed on the top of the tightening ring 42, and the internal thread of the fixing block 43 is connected to a threaded rod 44. A tightening belt 45 is wrapped around the surface of the threaded rod 44 close to the tightening ring 42. An annular groove is opened on the surface of the tightening ring 42, and the tightening belt 45 is wrapped around the inside of the annular groove. After the tightening belt 45 is tightened, it will pull the tightening ring 42 to be tightened.
[0028] The bottom of the connecting pipe 2 is inserted into the top of the external connecting pipe 5, and the bottom end of the fixed telescopic rod 32 first contacts the top of the external connecting pipe 5. At this time, the fixed telescopic rod 32 is pushed to shrink under the reaction of the external connecting pipe 5. In this process, the connection between the fixed telescopic rod 32 and the push rod 33 is constantly close to the sliding block 34, so the push rod 33 will push the push rod 33 to move to the side away from the center of the connecting pipe 2. At this time, the sliding block 34 will drive the buffer spring 35 to slide together in the groove 31, and the movement of the sliding block 34 will push the lever 36 through the buffer spring 35 to make the lever 36 rotate. At this time, the top end of the lever 36 rotates to the side away from the center of the connecting pipe 2, so the bottom end of the lever 36 rotates to the side close to the center of the connecting pipe 2. At this time, the lever 36 pushes the semicircular ring 37, so that the two semicircular rings 37 move against each other until they abut against the surface of the external connecting pipe 5. That is, at this time, the semicircular ring 37 blocks the connection between the external connecting pipe 5 and the connecting pipe 2 to prevent water vapor and moisture from causing rust at the connection between the connecting pipe 2 and the external connecting pipe 5.
[0029] Afterwards, the operator keeps pushing the connecting pipe 2 downward and manually rotates the threaded rod 44 at the same time. When the threaded rod 44 rotates, it will wrap around the tightening belt 45, so that the tightening belt 45 tightens the tightening ring 42. At this time, the bottom of the tightening ring 42 is tightened by the tightening ring 42 and is tightly attached to the surface of the external pipe 5, so that the external pipe 5 is pressed and tightly attached to the surface of the connecting pipe 2. After that, the operator releases and no longer presses the connecting pipe 2 downward. At this time, the friction between the connecting pipe 2 and the external pipe 5 and the tightening force of the tightening ring 42 on the external pipe 5 make the connection between the connecting pipe 2 and the external pipe 5 stable.
[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
