Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figures 1 to 4, a kind of rapid pipe joint 100 that is applied to air-conditioning system that relates to for the utility model shown in it, it comprises bull 1 and parent part 2, this bull 1 with parent part 2 salable windings be in the same place, this bull 1 and parent part 2 also all have receiving hole 11,21, and this receiving hole the 11, the 21st is used for cooling matchmaker circulation.A kind of concrete mode of execution as both windings, this bull 1 has outside thread, these parent part 2 inner edges then have the internal thread with this outside thread coupling, by the cooperation between this outside thread and the internal thread, thereby make this bull 1 and parent part 2 combine, realizing that as for sealing modes such as then can adopting seal ring this winding mode is not limited to be threaded certainly, can also be related domain winding mode commonly used.
For the rapid pipe joint 100 that makes the utility model relate to can be mated multiple pipe fitting in actual use, this bull 1 is being connected with pipeline 3 with the opposing end of parent part 2, and this parent part 2 also is being connected with pipeline 3 with the opposing end of this bull 1, the other end of this pipeline 3 can be provided with the endoporus 31 of various internal diameter sizes, thereby the demand of various pipelines 3 when satisfying actual the use, certainly in order to prevent secondary refrigerant leakage, be equipped with seal ring 32 between this bull 1 and parent part 2 and this pipeline 3.
Below to main improvement of the present utility model, i.e. the internal structure of bull 1 and parent part 2 is described in detail:
Also be equipped with motion bar 12 and spring 13 in this bull receiving hole 11, this motion bar 12 has head 121 and bar portion 122, this spring 13 is set in the motion bar 12 bar portions 122, and the two ends of this spring 13 are resisted against respectively on motion bar head 121 and bull receiving hole 11 inner edges, this spring 13 is squeezed state and promotes this motion bar 12 and moves to bull receiving hole 11 openings, these bull receiving hole 11 openings also have bulge loop 111, this bulge loop 111 is used to block this motion bar 12 to harness motion, be the sealing attitude in order to make between this motion bar 12 and the bulge loop 111, this motion bar head 121 also is arranged with sealing block 123, and sealing piece 123 can lean with this bulge loop 111.When parent part 2 did not link to each other with bull 1, sealing piece 123 leant with this bulge loop 111, thereby avoided the secondary refrigerant leakage in the bull receiving hole 11.
Also be equipped with in this parent part receiving hole 21 to bar 22, movable sheath 23 and spring 24, should support bar 22 afterbodys is fixed on the parent part 2, this movable sheath 23 is set in the front end to bar 22, this spring 24 also is set on bar 22, and two ends are resisted against respectively on parent part receiving hole 21 inner edges and the movable sheath 23, the outer rim of this movable sheath 23 links to each other with parent part 2 sealings, should support bar 22 front ends and also be arranged with sealing block 221, realizes sealing thereby sealing piece 221 can lean with the inwall of this movable sheath 23.When parent part 2 did not link to each other with bull 1, sealing piece 221 leant with movable sheath 23 inwalls, and the outer rim of this movable sheath 23 and parent part 2 sealings, thereby avoided the secondary refrigerant leakage in the parent part receiving hole 21.
When this parent part 2 links to each other gradually with bull 1, as shown in Figure 3, when soon bull 1 screws in the tapped hole of parent part 2 by the mode that is spirally connected gradually, this bull 1 can promote this movable sheath 23, make this movable sheath 23 overcome the elastic force of parent part receiving hole 21 medi-springs 24, and then to the opposing direction motion of bull 1, should support bar 22 and be separated with this movable sheath 23 this moment, thereby make parent part 2 be opening state; This moment, the continuation along with bull 1 screwed in parent part 2, should support bar 22 will contact with this motion bar 12, kept state of rest owing to should support bar 22, and can promote motion bar 12 towards the direction motion of parent part 2 dorsad, promptly overcame the elastic force of these bull receiving hole 11 medi-springs 13 so this supports bar 22; Also separated attitude between this moment this motion bar 12 and the bulge loop 111, thus this bull 1 also is in opening state, and then realized the conducting of bull 1 and parent part 2, and certain sealing between movable sheath 23 and bull 1 and parent part 2, refrigerant can not revealed outside.
So the rapid pipe joint 100 that relates to of the utility model is when this bull 1 and parent part 2 all are in notconnect state, the refrigerant in can airtight its receiving hole 11,21; And when bull 1 is connected with parent part 2, can utilizes this movable sheath 23 again and realize conducting to space between the bar 22 and the gap between this motion bar 12 and this bulge loop 111.So the utility model all can be guaranteed sealing in assembling when splitting, thus need not manually to seal, thus can avoid the leakage of refrigerant well.
A kind of embodiment as sealing on the movable sheath 23 is provided with first seal ring 231 between this movable sheath 23 and the parent part 2; And also be provided with second seal ring 232 at movable sheath 23 front ends.This first seal ring 231 guarantees to remain sealing state between this movable sheath 23 and the parent part 2 in the process of whole bull 1 and parent part 2 windings, and specifically it is arranged on the rear end of second seal ring 232.232 of this second seal rings are used for when bull 1 during with parent part 2 windings, the gap between sealing movable sheath 23 and the bull 1, thus guarantee that whole jointing is in the state of finishing sealing, guarantee that refrigerant can not reveal.
For the ease of the installation of spring 13, this motion bar bar portion 122 also is arranged with baffle plate 14, this baffle plate 14 and these receiving hole 11 inner edges against and be limited towards the motion of motion bar 12 afterbodys, spring 13 1 ends in this bull receiving hole 11 are resisted against on the baffle plate 14.And these motion bar 12 bar portions 122 also be arranged with ammunition feed spring 13 the other ends against baffle plate 14.Certainly this baffle plate 14 be not yet must with receiving hole 11 inner edges against, as long as make that this baffle plate 14 can't be to the direction motion of parent part 2 dorsad, can act on and fixed thereon by replacing of external pipeline 3 such as it, as shown in figures 1 and 3.
In order to save the material of this baffle plate 14, and make refrigerant to pass through baffle plate 14 more easily, as shown in Figure 6, this baffle plate 14 comprises the pedestal 141 with mesopore 142, and these pedestal 141 outer rims are protruding three catch 143 that are mutually 120 degree.
Support a kind of means of fixation of bar 22 afterbodys as this, should support on bar 22 afterbodys and be arranged with positioning disk 222 and fixed block 223, this positioning disk 222 is fixed on the parent part 2 and has outage 224, and this fixed block 223 should support bar 22 and be fixedly linked with positioning disk 222.This outage 224 can be so that the circulation of this refrigerant.Certainly this positioning disk 222 is not must be fixed on the parent part 2 yet, as long as making should to support between bar 22 and this parent part 2 to keep relative static, can act on and fixed thereon by replacing between external pipeline 3 and parent part receiving hole 21 inner edges such as it.
As shown in Figure 5, the rapid pipe joint 100 that the structural representation when it is applied on the air-conditioning system for the utility model, the utility model relate to is applied between expansion valve 4 and the condenser 5 and between vaporizer 6 and the compressor 7.
The foregoing description and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
