Description

Conversion sleeve for processing copper pipe

Technical Field

The utility model belongs to the technical field of red copper pipe processing, especially, relate to a conversion cover for red copper pipe processing.

Background

Red copper pipe, non-ferrous metal pipe. Is a pressed and drawn seamless tube. The copper tube has strong connection firmness, so that the copper tube has higher practical value. Because the tubular product on the market is various, the interface accessory uses the tubular product of copper to be the main, even some tubular product parts can not use the copper accessory, need use the adapter sleeve in the copper pipe course of working with the copper pipe connection of not unidimensional size. However, if the copper pipe fitting is connected with other pipes, the physical and mechanical properties of the pipe and the fitting are different due to different materials, and the firmness of connection naturally suffers from additional challenges. Therefore, the firmness of the connection between the copper pipe and the copper fitting is greatly enhanced.

At present, the connection between the copper tubes of current different size and dimension uses external accessory to connect mostly, need use special instrument to make the connection between the copper tubes more inseparable simultaneously, and this kind of connected mode is comparatively loaded down with trivial details, and the junction easily causes the damage to the copper tubes, is not convenient for improve the connection efficiency between the copper tubes.

Disclosure of Invention

An object of the utility model is to provide a change-over sleeve for processing of red copper pipe that connection efficiency is high is equipped with first round hole and second round hole at change-over sleeve both ends, has improved the connection efficiency of red copper pipe.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a conversion sleeve for processing a red copper tube, which comprises a conversion sleeve body, wherein a groove is arranged at one end in the conversion sleeve body, and a through hole is arranged in the groove; a first round hole is formed in the groove and close to one end face of the conversion sleeve body, and a second round hole is formed in the through hole and close to the other end face of the conversion sleeve body; the inner diameter of the first round hole is gradually reduced along the direction close to the through hole, and the inner diameter of the second round hole is gradually reduced along the direction close to the groove.

Further, the cross sections of the first round hole and the second round hole are both in an isosceles trapezoid structure.

Further, the size a of the outer diameter of the conversion sleeve body is 31.1mm, the size b of the inner diameter of the groove is 20mm, and the size c of the inner diameter of the through hole is 11.5 mm.

Further, the outer diameter of the conversion sleeve body is gradually reduced along the direction close to the through hole, and the inclination f of the outer surface of the conversion sleeve body is 3 degrees.

Further, the length e of the conversion sleeve body is 18mm, and the depth d of the groove is 13 mm.

The utility model discloses following beneficial effect has:

the utility model discloses a terminal surface at recess and through-hole is equipped with first round hole and second round hole respectively, and the copper tubing connection of being convenient for is in the conversion cover, and the cross-section of first round hole and second round hole all is the trapezium structure, the effectual damage of having avoided the surface to the copper tubing.

Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.
