By the above, how a kind of connection set of air-conditioning duct is provided, is difficult to once connect and put in place to solve existing connection set, cause development cost to raise, pollute, and there is the problem of potential safety hazard, become those skilled in the art and need badly the technical problem of solution.
Summary of the invention
In view of this, the invention provides a kind of joint that carries thimble, be difficult to disposable connection and put in place to solve existing connection set, cause development cost to raise, pollute, and have the problem of potential safety hazard.
For achieving the above object, the invention provides following technological scheme:
Carry a joint for thimble, comprise be provided with the copper sleeve of refrigerant through hole, the copper tube that is connected with refrigerant through hole sealing, be fixedly installed on copper tube inside thimble and be provided with the copper nut of shoulder hole;
One end of copper tube is fixedly installed on copper sleeve, and the other end is provided with the horn mouth expanding outwardly;
Thimble is towards a bell-mouthed side;
In shoulder hole, comprise successively positioning hole, chamfered bore and interior threaded hole, copper nut is set in outside copper tube by positioning hole, and chamfered bore and horn mouth have the surface that can fit each other.
Preferably, in above-mentioned joint, thimble side and copper tube are fixedly linked by riveted joint.
The invention provides a kind of joint that carries thimble, comprise copper sleeve, copper tube, thimble and copper nut.Wherein, on copper sleeve, be provided with copper tube and seal the refrigerant through hole being connected; One end of copper tube and described copper sleeve are fixedly linked, and the other end is provided with abducent horn mouth; Thimble is arranged in copper tube, towards horn mouth one side setting; On copper nut, be provided with the shoulder hole that comprises successively positioning hole, chamfered bore and interior threaded hole, chamfered bore and horn mouth have the surface that can fit each other, and copper nut is set in outside copper tube by positioning hole.
In the time connecting joint provided by the present invention and pressure spot copper sleeve, utilize the interior threaded hole on copper nut to match with the external thread section on pressure spot copper sleeve.Screw in the process of copper nut, on the one hand, pressure spot copper sleeve is pressed on horn mouth in chamfered bore, and realization is tightly connected; On the other hand, thimble backs down the spring needle valve in pressure spot copper sleeve, thereby makes pipeline communication.And in the time splitting joint provided by the present invention and pressure spot copper sleeve, only need unclamp being connected of copper nut and external thread section on pressure spot copper sleeve, along with thimble is return backward, spring needle valve seals pressure spot copper sleeve again, avoids secondary refrigerant leakage.
The joint that carries thimble provided by the present invention is easy to use, connects and fractured operation can one-time-reach-place, has reduced the leakage of refrigerant, has reduced development cost.Thimble is fixedly installed among street corner, the potential safety hazard of having avoided thimble to be ejected.
