Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1.

A kind of solar water heater quick change pipe joint, it comprises the adapter piece 8 that links to each other with water tank, the plug spare 2 that links to each other with heat pipe 1, seal ring 7, cutting ferrule 5 and steel ball 4, (this groove 9 both can be single disjunct groove, also can be an annular groove to be provided with the groove 9 that matches with steel ball 4 on the outer wall of described plug spare 2; During single groove, both can be cylindrical groove, also can be ball recess), be provided with two cone shape holes 10 (being the best wherein) at least with six at plug spare 2 relative position places, the Outside diameter of this cone shape hole 10 is greater than the diameter of steel ball 4, and its end diameter is then less than the diameter of steel ball 4; The main body of described steel ball 4 places described cone shape hole 10 and inserts described groove 9, cutting ferrule 5 is sleeved on the adapter piece 8 and by collar 3 and the convex shoulder on the adapter piece 8 that is installed on plug spare 2 outer walls and is positioned on the adapter piece 8, on adapter piece 8, also be set with Returnning spring 6, one end of Returnning spring 6 and the convex shoulder on the adapter piece 8 offset, the internal shoulder of the other end and cutting ferrule 5 offsets, and the inwall of the internal shoulder of cutting ferrule 5 matches with the outer wall of plug spare 8; The main body of described seal ring 7 is sleeved on the heat pipe 1, and it is provided with one and inserts shoulder 11 between adapter piece 8 and the plug spare 2 and that make the two sealing.

Details are as follows:

There is a semicircular groove that matches with steel ball 4 centre that is welded into the plug spare 2 of one with heat pipe 1, has one to be used to install the groove of jump ring 3 to prevent that cutting ferrule 5 is compressed spring 6 and ejects with tank weld or with the right-hand of the adapter piece 8 that is threaded.Adapter piece 8 has several (as 4,6,8 etc.) that the cone shape hole 10 of steel ball 4 is installed at the left of groove, these cone shape holes 10 are slightly less than the diameter of steel ball 4 in the aperture at inwall place, the slightly larger in diameter at outer wall place has a pressure spring 6 in steel ball 4 diameters between adapter piece 8 and cutting ferrule 5.

Plug spare 2 is metal circular tubular bodies, and its internal diameter and heat pipe 1 match, and is provided with groove 9 on its left end outer wall, in its inner radius of right-hand member a chamfering is arranged, and is one so that be welded with heat pipe.

Adapter piece 8 be one can be with the metal circular tubular body of hexagonal, the annular groove that a little semicircular installation jump ring 3 is arranged in its right part, left at annular groove has several cone shape holes 10, the aperture, inwall place of these cone shape holes 10 is slightly less than steel ball 4 diameters, aperture, outer wall place is slightly larger than steel ball 4 diameters, can be in the left part according to deciding its shape with the water tank ways of connecting, be threaded as employing and then can be threaded and structural type hexagonal, as adopt welding, then can be the structural type of not threaded or hexagonal.Outer wall in the middle of the adapter piece 8 matches with the internal diameter of cutting ferrule 5 and pressure spring 6 respectively, and the diameter and the shape of its inner diameter and shape and seal ring 7 match.

The inwall of seal ring 7 has been provided with the semicircle spheroid (not shown) of the convex of decompression, and the annular convex shoulder 12 on its left part outer wall is to take seal ring 7 in order to prevent out of in the process of loading and unloading heat pipe.The shoulder 11 of seal ring 7 right-hand members is to be used to insert between plug spare 2 and the adapter piece 8 so that pressurization the time seals, when preventing the water tank water flowing to external leakage.

Cutting ferrule 5 blocks steel ball 4 at ordinary times, and its outer diameter is consistent, can be provided with anti-skidding cotton ginning structure above, and the diameter of inwall is little in the middle of being, two is big.The internal diameter on the left side is slightly larger than pressure spring 6 external diameter when being crushed, and the internal diameter on the right is slightly less than adapter piece 8 mounting hole place external diameters and steel ball 4 diameter sums, and the intermediate portion internal diameter is slightly larger than adapter piece 8 cone shape holes 10 place's external diameters.Such structure makes cutting ferrule 5 when not having left thrust, its spring 6 that is reset withstands and stops with jump ring 3 and motionless in position all the time, the inwall of intermediate portion just in time blocks steel ball 4, and it is snapped in the groove 9 of plug spare 2, makes plug spare 2 and adapter piece 8 push down seal ring 7 and plays seal action.When cutting ferrule 5 being applied left thrust, compression reseting spring 6, cutting ferrule 5 is moved to the left, when left end major diameter place reaches steel ball 4 positions, steel ball 4 outwards skids off, and deviates from the semi-circle groove of plug spare 2, and just can relaxedly and rapidly load and unload heat pipe this moment, therefore can break away from groove 9 automatically for the ease of steel ball 4, a little Returnning spring can be installed in groove 9.

Jump ring 3 can adopt Spring Steel Wire, and the right-hand member semi-circle groove of its geomery and adapter piece 8 matches, and plays to stop cutting ferrule 5 to be compressed the position-limiting action that spring 6 ejects.

The diameter of steel ball 4 is greater than the aperture on the outer wall of aperture on the inwall of adapter piece 8 taper mounting holes and adapter piece 8 taper mounting holes.Under the effect of cutting ferrule 5, can embed in the groove 9 of plug spare 2 and play the role of positioning, also can when being moved to the left, cutting ferrule 5 skid off groove 9, so that heat pipe can relaxedly and rapidly load and unload.

The utility model can also have other mode of execution, and the technological scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.

The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.

Working procedure of the present utility model is: cutting ferrule 5 is postponed (seeing shown in Figure 2) left in external force, steel ball 4 in adapter piece 2 grooves outwards rolls out, after inserting plug spare 8, rut goes the thrust on the cutting ferrule 5, and Returnning spring 6 resets, on cutting ferrule 5 tops, steel ball 4 is embedded in the groove 10 of plug spares 8, and plug spare 8 invar balls 4 and being stuck make seal ring 7 under the pressure of plug spare 8 and adapter piece 2, and play seal action, make water in the water tank not to external leakage.In like manner, in external force cutting ferrule 5 is postponed left, steel ball 4 in adapter piece 2 grooves 9 outwards rolls out, plug spare 8 invar balls 4 no longer block groove and can extract like a cork, thereby can finish the installation and removal work of the water tank and the heat pipe of solar water heater apace, steel ball 4 cutting ferrule 5 left ends, diameter can not come off from the cone shape hole on the plug spare 8 10 under greater than the stopping of the internal face of its convex shoulder, therefore the stroke of cutting ferrule 5 must not only guarantee that steel ball 4 can expose but also can not come off from cutting ferrule 5 through calculating.
