Description
Technical field
The utility model is related to a kind of connectors, more particularly to a kind of copper sleeve for connection flexible pipe.
Background technology
Currently, the copper sleeve of the prior art is made of a tube body, one end is fixing end, and the other end is connecting pin, connection
End is the one end being connect with hose, and connecting pin is generally equipped with dentalation, and dentalation is higher than the periphery of rest part,
The junction of hose is distracted larger by dentalation when due to hose grafting, causes hose to be susceptible to junction thinning even
Damaged situation occurs, and the case where be susceptible to disengagement or leak in use, when pressure becomes larger suddenly, especially exists
In the case of separately not stepping up firmware, it is easier to the above situation occur；And add after fastener due to hose junction wall thickness
Thinning hose is easy to disconnect at thinning place；Furthermore when at low ambient temperatures, some hoses can be hardened, and more hold so as to cause hose
It is easy to fall off.Therefore the red copper pipe fitting of the prior art has that connective stability is poor and applicability is poor.
Utility model content
The utility model provides a kind of connective stability and the preferable copper sleeve of applicability in view of the above problems.
The utility model solve problem above used in technical solution be：A kind of copper sleeve having following structure is provided,
It includes tube body, and the tube body is divided into interconnecting piece, transition part and fixed part, and the interconnecting piece is connected by transition part and fixed part
It connects, the outer diameter of the transition part is more than the outer diameter of interconnecting piece, and the outer diameter of transition part is less than the outer diameter of fixed part, the transition part
Peripheral surface be equipped with first annular groove, and the corresponding diameter in first annular groove bottom surface be more than interconnecting piece outer diameter, the company
Socket part is divided into toothed segment and smooth section, and described toothed segment one end is connect with transition part, and the toothed segment other end is connect with smooth section, institute
The outer diameter for stating toothed segment is less than the outer diameter of smooth section, and the corresponding outer diameter in toothed segment tooth peak is equal to the outer diameter of smooth section, the saw
It is seamlessly transitted between tooth section and smooth section.
After using the above structure, compared with prior art, the utility model since the toothed segment other end is connect with smooth section,
The outer diameter of tooth section is less than the outer diameter of smooth section, and the corresponding outer diameter in toothed segment tooth peak is equal to the outer diameter of smooth section, toothed segment and light
It is seamlessly transitted between sliding section, then the junction of hose is softened relatively small when hose grafting, and the junction of hose is just not yet
Variable is relatively thin, is less prone to damaged situation；And since the corresponding outer diameter in toothed segment tooth peak is equal to the outer diameter of smooth section, then
The case where transition position of toothed segment and smooth section is susceptible to micro-vacuum during being inserted into hose so that the tube wall quilt of hose
It is firmly adsorbed on interconnecting piece, in use, i.e., is not easy to occur disengaging when pressure change is larger or the case where leak；And
Add fastener rear hose junction thinning still relatively small, therefore the stability of junction is also preferable；Furthermore even if in low temperature
When under environment, some hoses can be hardened, and under the action of micro-vacuum, hose is not easy to fall off, and applicability is preferable.Therefore this practicality
It is novel to have the characteristics that connective stability and applicability are preferable.
As an improvement, the junction of the transition part and fixed part is equipped with second annular groove；Then second annular groove is set
The case where postponing, being convenient for the withdrawing of the cutter head in processing, can prevent cutter head from crumbling.
As an improvement, the peripheral surface of the nearly second annular groove of the fixed part is equipped with first annular protrusion；Then the first ring
After the setting of shape protrusion, when mounted, it can play the role of to tube body axial limiting so that the stability after the utility model installation
More preferably.
As an improvement, peripheral surface of the fixed part far from first annular raised one end is equipped with third annular groove；Then
After the setting of third annular groove, it can be used for placing sealing ring so that sealing effect is more preferable after the utility model installation.
As an improvement, being arc-shaped transition between the bottom surface and side wall of the third annular groove；Due to third annular groove
It is relatively deep, then after arc-shaped transition setting so that in processing, cutter head is less prone to the case where crumbling, and improves production efficiency, into
And reduce production cost.
As an improvement, the peripheral surface of the fixed part is equipped with the second annular protrusion, and the second annular protrusion is located at first
On position between annular protrusion and third annular groove；Then after the setting of the second annular protrusion, when being assembled with fixing nut, Gu
Determine nut to be limited between the second annular protrusion and first annular protrusion so that the use of the utility model is more flexible.
As an improvement, the side wall of the nearly toothed segment of the first annular groove is inclined-plane；Then after inclined-plane setting so that installing
When on to equipment, inclined-plane can avoid some shells, while be suitable for a certain range interior installing hole again so that the utility model
Using flexible is more preferable.
