For realizing above-mentioned object, the utility model have employed following technological scheme.
A rapid pipe joint for refrigerant pipe, containing pipeline main body and sliding barrel, is characterized in that, arranges a boss at the front outsides of described pipeline main body, is provided with groove in the front end of described pipeline main body; The locking ring of an affixed cavity body structure on described boss, affixed with described boss after described locking ring, be the opening of locking ring cavity body structure before described locking ring, in locking ring cavity body structure, be socketed an annular spring by described opening; O RunddichtringO is connected at the front end sleeve of described pipeline main body; The top of described sliding barrel is made an enlarging, the internal diameter of described enlarging is greater than the external diameter of described pipeline body front end, is provided with outside flange on the top of described enlarging; The external diameter of described flange is less than the external diameter of described locking ring opening.
Further, at least two grooves (the first groove, the second groove) are set in the front end of described pipeline main body.
Further, in the groove described in every bar, O RunddichtringO is socketed with.
Further, at least two O RunddichtringOs (an O RunddichtringO, the 2nd O RunddichtringO) are connected at the front end sleeve of described pipeline main body.
The good effect of the rapid pipe joint of a kind of refrigerant pipe of the utility model is:
(1) by the improvement of pipe joint structure, make the pipe coupling disposable locking latch of energy and there is hermetic effect.
(2) in use particular/special requirement be there is no to assembly space, install very convenient.
(3) easy to make, after configuration frock, exchange or keep in repair also very convenient, obviously can reduce manufacture, install and maintenance cost.

Embodiment
Further illustrate the embodiment of the rapid pipe joint of a kind of refrigerant pipe of the utility model below in conjunction with accompanying drawing, but it is noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 3 and 4.A rapid pipe joint for refrigerant pipe, containing pipeline main body 31, boss 32, locking ring 33, annular spring 34, first groove 35, second groove 36, sliding barrel 37, enlarging 38, flange 39, an O RunddichtringO 310 and the 2nd O RunddichtringO 311.Described pipeline main body 31 and sliding barrel 37 are the structural member that employing 3003 or 6063 aluminum pipe section bar makes.First in the front end of described pipeline main body 31, at least two grooves (the first groove 35, second groove 36) are set by mold pressing.Then, equipment is utilized to form a boss 32 at the front outsides of pipeline main body 31, again locking ring 33 is enclosed within the front portion of described pipeline main body 31, utilize the spin slot of mould-forming pipeline main body 31 front end, locking ring 33 is fixed on described boss 32: described locking ring 33 is a cavity body structure simultaneously, affixed with described boss 32 after locking ring 33, be the opening of locking ring 33 cavity body structure before locking ring 33.
Then, in the cavity body structure of described locking ring 33, an annular spring 34 is socketed by described opening.The diameter of described annular spring 34 should be less than the width of described locking ring 33 opening.
Socket O RunddichtringO (an O RunddichtringO 310 and the 2nd O RunddichtringO 311) at least two grooves (the first groove 35, second groove 36) that described pipeline main body 31 front end is arranged again: be socketed an O RunddichtringO in each groove.The structural member that described O RunddichtringO can adopt related domain conventional.
An enlarging 38 is made on the top of described sliding barrel 37.The internal diameter of described enlarging 38 should be greater than the external diameter of described pipeline main body 31 front end.Arrange the outside flange of a circle 39 on the top of described enlarging 38, the external diameter of described flange 39 should be less than the external diameter of described locking ring 33 opening.Described enlarging 38 and flange 39 can together with machine.
The mode that connects soon of the rapid pipe joint of a kind of refrigerant pipe of the utility model is:
The enlarging 38 on sliding barrel 37 top is socketed in the front end of pipeline main body 31, the flange 39 on enlarging 38 top stretches in the cavity body structure of locking ring 33 by the opening (being backed down by annular spring 34) of locking ring 33, at this moment, the annular spring 34 itself be arranged in locking ring 33 cavity body structure is just stuck in the flange 39 times of enlarging 38 under elastic force effect, the thickness making flange 39 add annular spring 34 is less than the cavity body structure of locking ring 33 but is greater than the opening of locking ring 33, like this, described sliding barrel 37 is just locked in described pipeline main body 31.Be arranged on plural O RunddichtringO (an O RunddichtringO 310 and the 2nd O RunddichtringO 311) in the groove of pipeline main body 31 front end by its elastic structure just by the gap sealing between the outer wall of pipeline main body 31 and the inwall of sliding barrel 37.
Rapid pipe joint of the present utility model when operating in fact with regard to insert action that one " instantaneously " completes.
The mode of untiing of the rapid pipe joint of a kind of refrigerant pipe of the utility model is:
Because of maintenance or the replacement of pipe coupling need joint to untie time, a frock configured can be utilized carry out: described frock is inserted in the cavity body structure of locking ring 33 by the opening of locking ring 33, by annular spring 34 spreading, then the space that the enlarging 38 on sliding barrel 37 top is produced by described frock is unloaded in the locking ring 33 of pipeline main body 31, joint is untied.
