Detailed description of the invention
Below by specific embodiment, and combine accompanying drawing the technical solution of the utility model is described further.
Embodiment: with reference to Fig. 1, the stopping means that a kind of pipe fitting is rotationally connected, it includes rotating pipe 1, rotation seat 2, pivot pin 3, positioning pipe 4, positioning seat 5, alignment pin 6；It is characterized in that rotating pipe 1 is fixed on rotation seat 2 by pivot pin 3, positioning seat 5 is fixed on positioning pipe 4 by alignment pin 6, and positioning seat 5 is installed in rotation seat 2.
With reference to Fig. 2, described rotation seat 2 is provided with linking arm 21, link slot 22, location hole 23, rotation slot 24, stopper slot 25, installs rotation pipe 1, and by installing pivot pin 3 in hole 23, location, be fixed together with rotation seat 2 by rotation pipe 1 in described link slot 22；Rotation slot 24 is coaxially disposed with stopper slot 25, installs positioning pipe 4 in rotation slot 24, and the cross sectional shape set by rotation slot 24 matches with the cross sectional shape of positioning pipe 4, and allows positioning pipe 4 within it to rotate；Cross sectional shape set by stopper slot 25 and positioning seat 5 rotate produced cross sectional shape in set rotational angle and match；Being provided with position limit arm 251, spline boss 252 in described stopper slot 25, described position limit arm 251 is an inclined-plane, and spline boss 252 is a strip convex tendon highlighting surface.
With reference to Fig. 3, described positioning seat 5 is provided with spacing inclined-plane 51, locating piece 52, open slot 53, locating slot 54, fixing hole 55, countersunk head hole slot 56, the two described tapered settings in spacing inclined-plane 51, tapered tip is provided with locating piece 52, open slot 53 is arranged on the spacing inclined-plane 51 of side, locating piece 52 is made to have certain elasticity, can move to axle center under by external force pressure, so that the shortening along axes movement locus radius of locating piece 52, after cancelling external force, locating piece 52 utilizes natural resiliency, returns in situ, it is achieved positioning function；Installing positioning pipe 4 in locating slot 54, the cross sectional shape of locating slot 54 matches with the cross sectional shape of positioning pipe 4, and fixing hole 55 becomes axis perpendicular to arrange with locating slot 54, installs alignment pin 6 in fixing hole 55, and countersunk head hole slot 56 is used for the head of placement positioning pin 6.
