The inner wall of the middle part of the main body 1 is provided with a positioning part 12 which is annular.
The elastic notch 11 is an oblique notch.
The cross section of the sealing ring 5 is elliptical.
The outer wall of the main body 1 is provided with a plurality of anti-slip grooves 13 which are uniformly distributed in the circumference.
The application method of the utility model is as follows:
when the pipeline needs to be connected with the main body 1, one end of the pipeline can pass through the enclasping piece and penetrate into a port of the main body 1, at the moment, the enclasping piece 3 is sleeved outside the pipeline, at the moment, the fastening nut 6 can be rotated, so that the pipeline moves towards the middle direction of the main body 1, as a moving distance 9 is reserved between the inner conical surface 8 and the end surface of the main body 1, the fastening nut 6 cannot be limited when moving towards the middle direction of the main body 1, the inner conical surface 8 is attached to the outer conical surface 10, the diameter of the inner conical surface 8 and the diameter of the outer conical surface 10 are continuously increased towards the middle direction of the main body 1, when the fastening nut 6 is continuously close to the middle of the main body 1, the inner conical surface 8 synchronously moving along with the fastening nut 6 can continuously extrude the outer conical surface 10 to continuously tighten the outer conical surface 10, at the moment, and the existence of the elastic notch 11 can continuously narrow the enclasping piece 3 under the extrusion of the inner conical surface 8, so that the pipeline positioned in the pipeline is tightly clamped, the fixed connection between the pipeline and the enclasping piece 3 is realized, and the main body 1 and the enclasping piece 3 are fixedly connected through the fastening nut 6, and the pipeline is fixedly connected with the pipeline 1 when the pipeline and the enclasping piece 3 are fixedly connected.
When pipeline one end penetrates to the inside of main part 1 tip through holding part 3, the pipeline passes sealing washer 5 simultaneously, sealing washer 5 is direct to be overlapped outside the pipeline this moment, when pipeline and main part 1 accomplish fixed connection, sealing washer 5 can effectively guarantee the leakproofness between pipeline and the main part 1, if there is the rivers to outside infiltration, rivers then need to flow to extrusion conical surface 2 through the clearance between pipeline tip outer wall and the main part 1 inner wall earlier, when rivers flow to extrusion conical surface 2 positions, rivers then can extrude sealing washer 5 along the orbit of extrusion conical surface 2, under sealing washer 4's restriction, along with sealing washer 5 constantly by rivers extrusion, sealing washer 5 then can take place the inflation, sealing washer 5 inner wall further laminates on the pipeline outer wall, sealing washer 5 outer wall further laminates on extrusion conical surface 2, thereby further improve sealing washer 5's sealed effect, avoid taking place the condition of leaking.
Even sealing washer 5 still can expand because the circumstances that becomes flexible appears in long-term use, thereby sealing washer 5 still can take place to expand under the extrusion of rivers, thereby guarantee the inseparable laminating of sealing washer 5 all the time on the pipeline outer wall, guarantee the sealed effect of sealing washer 5 all the time, because the diameter of extrusion conical surface 2 increases gradually towards the direction of keeping away from main part 1 middle part, consequently, extrusion conical surface 2 has the effect of guiding rivers, when sealing washer 5 is too not hard up, rivers are likely to follow the orbit between sealing washer 5 outer wall and the extrusion conical surface 2 and flow direction gasket 4 along the clearance between the extrusion conical surface 2, gasket 4 is laminated mutually with main part 1 terminal surface this moment, laminating between the two forms one and seals, effectively avoid rivers to continue outside seepage, the rivers in the space that sealing washer 5 at this moment is adjacent to be close to main part 1 is less, and rivers are more water pressure are bigger more, consequently, sealing washer 5 then can closely laminate with gasket 4 under the effect of big water pressure, further with pipeline outer wall under the effect of sealing washer 5, thereby make sealing washer 5 laminate closely with gasket 4 laminating with the clearance between the main part and gasket 4, laminate under the effect of little water pressure, and the sealing washer 1 can be guaranteed under the sealing performance of the furthest when laminating with the main part is formed under the sealing 1.
The middle part inner wall of main part 1 is equipped with one and is annular location portion 12, and the existence of location portion 12 can penetrate to the main part 1 in the back at the pipeline through main part 1 port and play the effect of location, simultaneously, along with the pipeline terminal surface laminating mutually with location portion 12, can form new sealing, further improves the leakproofness when pipeline and main part 1 are connected.
The elastic notch 11 is an oblique notch, the structural design is more beneficial to the rapid tightening of the enclasping piece 3 when being pressed, the inclination angle of the oblique notch can effectively ensure the stability of the elastic notch 11 when continuously shrinking along the rotating direction of the fastening nut 6, and therefore the tightness and the tightness of the enclasping piece 3 after enclasping the pipeline are ensured.
When the cross section of the sealing ring 5 is elliptical, when the sealing ring 5 is sleeved outside the pipeline, only the inner wall of the middle part of the sealing ring 5 is actually attached to the outer wall of the pipeline, and the end, adjacent to the middle part of the main body 1, of the sealing ring 5 is attached to the extrusion conical surface 2, so that when water flows through the outer wall of the pipeline and the inner wall of the main body 1 permeate to the position where the extrusion conical surface 2 is located, the contact area between the inner wall of the sealing ring 5 and the water flow is far greater than the contact area between the outer wall of the sealing ring 5 and the water flow, the inner wall of the sealing ring 5 is pressed more, the outer wall of the sealing ring 5 can be further attached to the extrusion conical surface 2 through the inner wall of the sealing ring 5, the diameter of the extrusion conical surface 2 gradually increases towards the direction away from the middle part of the main body 1, the flowing direction of the water flow is also towards the direction away from the middle part of the main body 1, and the condition that the inner wall of the end, adjacent to the middle part of the sealing ring 1, of the sealing ring is turned outwards easily occurs at the moment, so that the inner wall of the end, adjacent to the middle part of the main body 1 of the sealing ring is further pressed on the outer wall of the pipeline, and the sealing effect of the sealing ring 5 is further improved.
The outer wall of the main body 1 is provided with a plurality of anti-slip grooves 13 which are uniformly distributed in circumference, and the existence of the anti-slip grooves 13 can effectively increase the friction between hands and the main body 1, so that the hands can apply force on the main body 1, the disassembly work of the fastening nut 6 is facilitated, and the maintenance and the replacement of other parts are facilitated.
