Embodiment
With the following Examples the utility model is further described.
embodiment 1
As shown in Figures 1 to 3, a kind of joint, comprises connecting head body 1, dog clutch 2, card cap 3, and card cap 3 is socketed on the connecting end 11 of connecting head body 1, and dog clutch 2 is installed in the inner chamber of the connecting end 11 of connecting head body 1, and dog clutch 2 is for being connected with pipeline.The outer surface of the connecting end 11 of described connecting head body 1 is equipped with the card convex 110 of protrusion, and the side end face of described card cap 3 offers hole clipping 30, and described hole clipping 30 is through the side end face of described card cap 3, and described card convex 110 is buckled in described hole clipping 30.
By arranging hole clipping 30 in the side end face of card cap 3, during clamping with hole clipping 30 of card convex 110, card convex 110 and card cap 3 are all in unexpanded mode, can reduce and the tension force of card cap 3 is expanded, prevent the premature aging of card cap 3, thus ensure the sealing between card cap 3 and connecting head body 1, prevent gas leakage from leaking.
Card convex 110 is intuitively visible with the coupled condition of card cap 3, and the area of hole clipping 30 is large, and it is convenient to install, and defective products rate is low.
Card convex 110 is exposed in the hole clipping 30 of card cap 3, and convenient coupled condition of observing card convex 110 and card cap 3, makes quality testing intuitive and convenient more, improves quality monitoring performance when producing.
The quantity of described card convex 110 is two, and described card convex 110 is symmetrical arranged.Two card convexs 110 are symmetricly set in the outer surface of connecting end 11 in 180 °, snapping performance is good, the dynamics too much card convex 110 can being avoided to cause during two symmetrical card convex 110 snappings is uneven and gas leakage that is that cause is leaked, and sealability is better, and can reduce the required precision of processing.But the utility model does not get rid of the quantity that can increase card convex 110.
Described card convex 110 is protruding gradually from top to bottom, and shown in figure 2, the entry end of connecting end 11 is upper, under with connecting head body 1 linking part being.When card convex 110 is connected in described hole clipping 30, card convex 110 stretches in described hole clipping 30, and the outer surface of described connecting end 11 and the inwall of described card cap 3 fit tightly.Card convex 110 is protruding gradually from top to bottom, and the installation of convenient card cap 3 is inserted in, and the outer surface of connecting end 11 and the inwall of card cap 3 fit tightly, then can improve sealing, and the diameter requirement on machining accuracy herein for connecting end 11 and card cap 3 is higher.
As shown in Figure 4, the width h of the bottom surface of described card convex 110 is 1/3-3/4 of the wall thickness H of described hole clipping 30.The bottom surface of card convex 110 is the key components be connected and fixed with card cap 3.If the bottom surface width h of card convex 110 is too small, then firm not with the connection of card cap 3, easily loosen.If the bottom surface width h of card convex 110 is excessive, then, after card convex 110 is connected with card cap 3, card convex 110 protrudes from outside hole clipping 30, is easily hit by external force, occurs to loosen.Therefore preferred, the width h of the bottom surface of card convex 110 is 1/3-3/4 of the wall thickness H of described hole clipping 30, and more preferably, the width h of the bottom surface of card convex 110 is 3/4 of the wall thickness H of described hole clipping 30, and its steadiness and sealing are all comparatively excellent.
Described dog clutch 2 is connected in described card cap 3.Described dog clutch 2 comprises connecting tube entry end and connecting end portion, and connecting end portion is made up of three calvus 20.
Concrete, the connecting end portion of dog clutch 2 by three calvus 20, the outer wall annular groove of calvus 20, for being connected with card cap 3, the inwall lower end of calvus 20 is provided with projection, for pipeline clamping.
Also be provided with seal ring 4 in the cavity of described connecting end 11, described seal ring 4 abuts with the lower end surface of described dog clutch 2.Seal ring 4 abuts with the lower end surface of dog clutch 2, for improving sealability.Preferably, the internal diameter width of seal ring 4 is equal with the internal diameter of the water inlet diameter of connecting head body 1, pipeline, ensures three junction surface sealings.
The inwall of described card cap 3 is provided with for the connecting ring with the clamping of described dog clutch 2, described connecting ring from up to down comprises the first oblique anchor ring 31 connected successively, vertical anchor ring 32 and the second oblique anchor ring 33, described first oblique anchor ring 31 is from tilting outside to inside, and the described second oblique anchor ring 33 tilts from inside to outside.First oblique anchor ring 31 is convenient to the installation of dog clutch 2, and vertical anchor ring 32 seals for abutting with dog clutch 2 outer wall, prevents from leaking.Second oblique anchor ring 33 prevents dog clutch 2 from loosening, and reduces the precision of processing.
Described connecting head body 1 is metal, and described dog clutch 2 and card cap 3 adopt PPO＝ polyphenylene oxide material.Polyphenyl ether material has explosion-proof anti crack performance, and puts corrosion, and oxidation resistance is excellent.
Described connecting head body 1 is tee union, and be mainly used in the water purification plant fields such as water purifier, tee union function is more complete.The present embodiment also can be applied to single joint, two pass joints, cross fitting etc.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
