Preferably: the VC lower cover is inlaid and installed in the graphite jig.

Preferably: four groups of limit posts are fixedly connected to two ends of the copper pipe main body.

Preferably: the slot is internally and fixedly provided with a connecting column, and four groups of limiting grooves are formed in the connecting column.

Preferably: one end of the second connecting ring and the connecting column are kept at the same level.

Preferably: the size of the first connecting ring is identical with that of the second connecting ring, and the first connecting ring and the second connecting ring are welded together in a diffusion welding mode.

Preferably: the limiting column is located in the inner cavity of the plug-in ring, and a layer of sealing gasket is arranged at one end, away from the first connecting ring, of the plug-in ring.

Compared with the prior art, the utility model has the beneficial effects that:

When the copper pipe is used, the plug-in ring is inserted into the slot and can squeeze the sealing gasket, so that after the copper pipe main body is connected with the connector, good sealing performance can be kept in the cavity of the copper pipe main body, at the moment, the second connecting ring can be attached to the first connecting ring, and when the second connecting ring is welded with the first connecting ring, the solder cannot enter the inner cavity of the copper pipe main body and pollute the cavity of the copper pipe main body due to blocking of the plug-in ring and the connecting column, and the yield and the performance are improved; after inserting the inserting ring into the slot, four groups of limit posts can be inserted into four groups of limit grooves simultaneously, so that when the first connecting ring and the second connecting ring are welded, the copper pipe main body and the connector cannot rotate, and welding operation between the first connecting ring and the second connecting ring is facilitated.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the 3DVC welded copper pipe structure of the present utility model includes a copper pipe main body 1, two ends of the copper pipe main body 1 are fixedly sleeved with a first connecting ring 2, the first connecting ring 2 is fixedly connected with a plugging ring 3, the plugging ring 3 can be inserted into a slot 5 formed by a connector 4, the connector 4 is fixedly connected with a second connecting ring 6, and two groups of connectors are respectively and fixedly installed on a VC upper cover 7 and a VC lower cover 8.

The VC lower cover 8 is inlaid and installed in the graphite jig 9, so that the structure is stable.

Four groups of limiting columns 10 are fixedly connected to two ends of the copper pipe main body 1, and the four groups of limiting columns 10 can be inserted into four groups of limiting grooves 12 formed in the connecting column 11.

The connecting column 11 is fixedly installed in the slot 5, four groups of limiting grooves 12 are formed in the connecting column 11, the four groups of limiting grooves 12 formed in the connecting column 11 can be inserted into the four groups of limiting grooves 10, so that when the first connecting ring 2 and the second connecting ring 6 are welded, the copper pipe main body 1 and the connector 4 cannot rotate, and welding operation between the first connecting ring 2 and the second connecting ring 6 is facilitated.

One end of the second connecting ring 6 and the connecting column 11 are kept at the same level, so that after the plugging ring 3 is inserted into the slot 5 formed in the connector 4, the second connecting ring 6 can be attached to the first connecting ring 2, and welding is facilitated.
