The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.
Referring to fig. 2-4, the present utility model provides a technical solution:
the utility model provides an anti vibration type screw thread union, including external screw thread end 1, sealing washer 2, intermediate nut 3, anti vibration ring 5 and joint base 4, be provided with spacing ring 6 on the tip of joint base 4, anti vibration ring 5 cover is established on joint base 4 and tip and the cooperation of spacing ring 6, be provided with the outer conical surface on the spacing ring 6, the one end cover of intermediate nut 3 is established on spacing ring 6, the other end inner wall and the outer wall screw thread end 1 of intermediate nut 3 screw-thread fit, be provided with on the intermediate nut 3 with the outer conical surface complex internal conical surface, be provided with the opening 7 that runs through on the anti vibration ring 5 lateral wall, external screw thread end 1 and joint base 4 coaxial setting are provided with the first water conservancy diversion passageway 8 that runs through in the external screw thread end 1, be provided with in the joint base 4 run through and with first water conservancy diversion passageway 8 complex second water conservancy diversion passageway 9, be provided with sealing washer 2 between the tip of external screw thread end 1 and the tip of joint base 4. The planes of the side surfaces of the two sides of the opening 7 pass through the axial lead of the anti-vibration ring 5. In this technique, the screw thread loose joint comprises external screw thread end 1, sealing washer 2, intermediate nut 3, connect base 4 and anti vibration ring 5, it has added an anti vibration ring to connect base 4 and intermediate nut 3 part, anti vibration ring 5 makes connect base 4 and intermediate nut 3 close together, thereby make connect base 4 and intermediate nut 3 reach resonance and play anti vibration effect, anti vibration ring 5 has an opening 7, opening 7 can become open state naturally when loosening, can compress tightly anti vibration ring when intermediate nut 3 is screwed up, anti vibration ring can produce the deformation, opening 7 department can be out of shape and close, opening 7 closed state can be tighter more, also can more hug tightly and connect base 4, the anti vibration effect that reaches is better, and the lower extreme screw thread of external screw thread end 1 pushes down closely sealing washer 2 when intermediate nut 3 is screwed up, spacing ring 6 can push up anti vibration ring 5, make anti vibration ring 5 warp and can hug tightly connect base 4, make and intermediate nut 3 can be out of shape, make the external screw thread end 1 more closely connect with intermediate nut 3 and the internal screw thread more tight, prevent that the external screw thread of external screw thread end 1 from more from loosening down. When in compression, the anti-vibration ring 5 can deform, the outer conical surface is clung to the inner conical surface of the compression nut, and the end part of the anti-vibration ring 5 is pressed on the limiting ring 6, so that the resonance effect is achieved, and the anti-vibration effect is achieved.
In some embodiments, the ends of the anti-vibration ring 5 extend to 2-5 mm outside the ends of the middle nut 3. The width of the opening 7 is 3-4mm, and when the external thread end 1 and the middle nut 3 are completely locked, the width of the opening 7 is smaller than 1mm. The lower part of the bottom of the anti-vibration ring 5 can be longer than the middle nut 3 and can be exposed by 2.5mm, whether the anti-vibration ring is put in place or not can be observed, and the opening 7 can also be exposed, an independent measurer can be used for measuring the width of the opening 7, the measurer can detect whether the opening 7 is closed in place or not, a middle measuring piece on the measurer is 1mm, the opening 7 is in a holding state when the holding gap is not greater than 1mm, the lower end external thread tightening state of the middle nut 3 and the external thread end 1 is achieved, and the pressing and sealing effects between the external thread end 1 and the joint base 4 are optimal at the moment. The traditional method can only judge whether the movable joint is fastened according to the screwing or thread number of the threads, and does not have a fixed mode or an accurate method to judge whether the movable joint is fastened, so that when the movable joint is used, the movable joint is loosely connected, but tightly connected, and the use safety is affected. The width of the opening 7 of the anti-vibration ring 5 is 3-4mm, the angle of the outer conical surface of the anti-vibration ring 5 is 30-45 degrees, and the middle nut 3 is 2-5 mm longer than the anti-vibration ring 5.
In some embodiments, the end of the joint base 4 is coaxially provided with a limiting protrusion 10, the end of the external thread end 1 is coaxially provided with a limiting groove 11 matched with the limiting protrusion 10, the first diversion channel 8 passes through the middle of the limiting groove 11, the second diversion channel 9 passes through the middle of the limiting protrusion 10, and the sealing gasket 2 is sleeved on the limiting protrusion 10. The cross sections of the limiting protrusion 10 and the limiting groove 11 are circular and coaxially arranged. The first diversion channel 8 and the limit groove 11 are coaxially arranged, and the second diversion channel 9 and the limit protrusion 10 are coaxially arranged. Wherein, set up spacing protruding 10 and spacing recess 11 and make the joint base 4 better with external screw thread end 1 is connected, easier assembly. The first diversion channel 8 and the second diversion channel 9 are both liquid flow channels.
The screw thread union can not be damaged during transportation and assembly, thereby vibration-proof effect can be played in vibration-proof ring 5 can produce resonance, can make external screw thread end 1 and middle nut 3 connect inseparabler simultaneously, can effectively prevent to drop, vibration-proof ring 5 is about to be longer than middle nut 3, so make opening 7 also can observe with the naked eye, can audio-visual middle nut 3 that sees union junction and external screw thread end 1 have not screwed up, and have special caliber to measure, the width of measuring opening 7 can be more convenient know the union degree of screwing up, after screwing up, use the measuring needle of caliber to insert in opening 7, just in time insert or insert and screw in for the union state of screwing up, make the operation simpler more convenient and safer like this. The inner diameter of the anti-vibration ring 5 is 27mm, the outer diameter is 37mm, the measurer is provided with a detection needle, and the inner thickness of the front end of the detection needle is 3mm and is 1mm.
The screw movable joint can be subjected to external force or other factors to cause vibration of the joint base end 5 in transportation, installation and use, but the middle nut 3 is not affected, the middle nut 3 and the external screw thread end 1 can be loosened, and the vibration-proof ring 5 can tightly hold the joint base end 5 when being screwed up, so that the joint base end 5 and the middle nut 3 are tightly connected, resonance of the joint base end is realized, and the vibration-proof movable joint is safer when in use. Whether the middle nut 3 is screwed or not can be judged from the screwing of the middle nut 3 until the middle nut 3 is screwed or not, whether the middle nut 3 connected with the two ends of the movable joint figure 2 is screwed or not can be well seen by adding the anti-vibration ring 5, the screwing degree of the middle nut 3 is judged according to the opening closing degree, and an independent measuring tool is additionally arranged, so that whether the joint connection is screwed or not can be well determined, and the movable joint is more convenient and safer to use.
