Connecting structure of metal hose and connecting pipe

Technical Field

The utility model relates to a metal collapsible tube connects technical field, provides a metal collapsible tube and connection structure who takes over very much.

Background

The conventional metal hose welding structure is formed by welding a corrugated pipe and a connecting pipe at one time, when the structure is used in coastal environments such as high humidity and high salt fog, the use requirements of users cannot be met, a welding seam of the structure can be in direct contact with an inner cavity medium, and oxidation color which is difficult to remove and a slit structure which is difficult to remove excess materials are easy to exist near the welding seam.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a metal collapsible tube and connection structure who takes over.

The utility model discloses a realize like this, a metal collapsible tube and connection structure who takes over, metal collapsible tube's both ends are vertical connection face, the outer end of connecting the face flushes with the surface of taking over, the surface laminating of connecting the face is on the terminal surface of taking over, it presses the outer end of connecting the face and takes over the position that the surface flushed to be equipped with the crimping piece, the crimping piece is connected the formation perpendicularly through a cartridge type ring and a piece type ring, the cartridge type ring is pressed at the takeover surface, the piece type ring is pressed on connecting the face, the other end and the takeover welding of cartridge type ring, the other end and the connection face welding of piece type ring.

Preferably, the medial surface of barrel-type ring is equipped with the annular groove, installs first sealing ring in the annular groove, the medial surface of piece type ring also is equipped with the annular groove, installs the second sealing ring.

Further preferably, the outer side of the end socket at one end of the cylindrical ring welded with the connecting pipe is an annular inclined plane, and the outer side surface of the end socket at one end of the sheet type ring welded with the connecting surface is also an annular inclined plane.

Further preferably, the cylinder ring and the blade ring are integrally formed.

Compared with the prior art, the utility model has the advantages of:

the metal hose and the connecting gap of the connecting pipe can be well protected, the welding seam is transferred, external air is prevented from directly contacting with the medium in the pipe, and the sealing performance is good, neat and attractive.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and embodiments:

FIG. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a schematic view of a cylindrical ring direction structure of the crimp member;

FIG. 3 is a top view of FIG. 2;

FIG. 4 is a view showing the connection structure of the pressure welding member with the inclined surface and the adapter tube.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Refer to fig. 1, fig. 2 and fig. 3, the utility model provides a metal collapsible tube and connection structure who takes over, metal collapsible tube 1's both ends are vertical connection face 101, the outer end of connecting face 101 flushes with the surface of taking over 2, the surface laminating of connecting face 101 is on the terminal surface of taking over 2, it presses the position that outer end and the 2 surfaces of taking over of connection face 101 to be equipped with crimping piece 3, crimping piece 3 is connected the formation perpendicularly through a section of thick bamboo type ring 301 and a piece type ring 302, section of thick bamboo type ring 301 presses and is taking over 2 surfaces, piece type ring 302 presses on connecting face 101, the other end and the 2 welding of taking over of section of thick bamboo type ring 301, the other end and the connection face 101 welding of piece type ring.

When the metal hose 1 and the adapter 2 are connected together, the sheet type ring 302 is pressed against the connecting surface 101, the cylindrical ring 301 is pressed against the adapter 2, and the sheet type ring 302 is welded to the connecting surface 101 and the cylindrical ring 301 is welded to the adapter 2, thereby connecting the metal hose 1 and the adapter 2. Since the metal hose 1 and the crimping member 3 are both circular structures, the crimping member 3 restricts all directions of the metal hose 1, and therefore the metal hose 1 does not fall off.

In order to increase the sealing performance and prevent the medium in the pipe from leaking or air from entering the medium, as an improvement, the inner side surface of the barrel-shaped ring 301 is provided with an annular groove, the first sealing ring 4 is installed in the annular groove, and the inner side surface of the sheet-shaped ring 302 is also provided with an annular groove and provided with a second sealing ring 5.

Because welding can generate redundant and irregular welding seams, for the sake of attractive appearance, as an improvement of the technical scheme, the outer side of the end of the welding end of the cylinder-shaped ring 301 and the connecting pipe 2 is an annular inclined surface, and the outer side of the end of the welding end of the sheet-shaped ring 302 and the connecting surface 101 is also an annular inclined surface.

In order to increase the sealing performance, as a technical improvement, the cylinder type ring 301 and the sheet type ring 302 are integrally manufactured. This is applicable to the case where the maximum diameter of the metal hose 1 is smaller than the inner diameter of the sheet type ring 302, and when it is equal to or smaller than this, the pressure-bonding member 3 may be divided into two parts, and the two parts are pressed against the metal hose and the adapter tube, respectively, and then welded together.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
