Thimble is towards bell-mouthed side；
Location hole, chamfered bore and internal thread hole is included successively, copper nut is set in copper tube by location hole in shoulder hole
Outward, chamfered bore has, with horn mouth, the surface that can fit each other.
Preferably, in above-mentioned joint, thimble side and copper tube are fixedly linked by riveting.
The invention provides a kind of joint carrying thimble, including copper sleeve, copper tube, thimble and copper nut.Wherein, copper
The coolant through hole being connected with the red copper seal of tube is provided with joint；One end of copper tube is fixedly linked with described copper sleeve, another
End is provided with abducent horn mouth；Thimble is arranged in copper tube, towards the setting of horn mouth side；It is provided with copper nut
Include the shoulder hole of location hole, chamfered bore and internal thread hole successively, chamfered bore has, with horn mouth, the surface that can fit each other,
Copper nut is set in outside copper tube by location hole.
When connecting joint provided by the present invention with pressure spot copper sleeve, using the internal thread hole on copper nut and pressure
External thread section on point copper sleeve matches.During screwing copper nut, on the one hand, horn mouth is compressed by pressure spot copper sleeve
In chamfered bore, realize being tightly connected；On the other hand, thimble backs down the spring needle valve in pressure spot copper sleeve, so that pipeline
Connection.And when splitting joint provided by the present invention with pressure spot copper sleeve, copper nut and pressure spot copper sleeve only need to be unclamped
The connection of upper external thread section, returns backward with thimble, and pressure spot copper sleeve is sealed by spring needle valve again, it is to avoid coolant is let out
Dew.
The joint carrying thimble provided by the present invention is easy to use, connect and fractured operation can one-time-reach-place, reduce
The leakage of coolant, reduces development cost.Thimble is fixedly installed among street corner, it is to avoid the safety that thimble is ejected is hidden
Suffer from.
