Fig. 1 to Fig. 6 is referred to, what Fig. 1 to Fig. 6 was disclosed is a kind of the first embodiment of air line fast connector,
Coupling assembly 2 used by present embodiment is straight-through coupling assembly 24, and referring first to Fig. 1 to Fig. 2, a kind of air line quickly connects
Joint, including at least two anchor ears 1, the straight-through coupling assembly being connected between two anchor ears 1 and with the anchor ear 1
24th, and the sealing ring 3 equal with 1 quantity of the anchor ear, on the inwall 15 of each anchor ear 1 with the straight-through connection
The junction of component 24 is provided with annular groove 111（As shown in Figure 3, Figure 4）, the internal diameter of the port 20 of the straight-through coupling assembly 24
Expand and outwards curved extension forms the first holding part 41, the end of first holding part 41 stretches out to form sticking part
22, radially outwardly projecting of the sticking part 22 along the straight-through coupling assembly 24, and the position of projection is simultaneously to away from described
The direction of port 20 extends, and forms the first chimeric bulge loop 51 corresponding with the annular groove 111 on anchor ear 1；In the present invention, as general
After the straight-through coupling assembly 24 is connected with pipeline to be connected 9, then described each anchor ear 1 is fixed on into the straight-through coupling assembly
24 are embedded in the annular groove 111 with the joint of pipeline to be connected 9, the first bulge loop 51 of the straight-through coupling assembly 24,
Now, the second holding part 42 is formed between the medial wall 1110 of the annular groove 111 and the port 221 of the sticking part 22,
The sealing ring 3 is placed in second holding part 42, so, and each described sealing ring 3 is all placed in second holding part 42
Interior and with the sticking part 22 port 221 is brought into close contact；In the present invention, the anchor ear 1 causes the straight-through coupling assembly 24
It is more firm with the connection between pipeline to be connected 9, and, each described sealing ring 3 be placed in each described anchor ear 1 with it is described
In the second holding part 42 that straight-through coupling assembly 24 is collectively forming, in this manner it is possible to so that the straight-through coupling assembly 24 with treat
Better tightness between connecting pipe 9；And, for the connection that pipeline needs at turning and divided fluid stream etc., only need
Straight-through coupling assembly 24 is replaced with into elbow coupling assembly 25 and three-way connecting module 26, the anchor ear 1 of employing is torn open
Dress is convenient so that the present invention is highly susceptible to keeping in repair and safeguards.
Refer to Fig. 5 to Fig. 7, in the present invention, in order to further strengthen sealing effectiveness, while so that the sealing ring 3 more
Plus be firmly fixed in second holding part 42, set between first bulge loop 51 and the outer wall 220 of the sticking part 22
There is the first certain gap 43, second holding part 42 is communicated with first gap 43, second bulge loop 52 is to described
30 direction of compressed part bends, and forms the embedded division 301 with 43 corresponding matching of the first gap；It is when union joint is installed, described
The embedded division 301 of sealing ring is placed in first gap 43.
In the present invention, in order that the connection between the straight-through coupling assembly 24 and pipeline to be connected 9 is even closer, often
31 internal diameter of front end of the individual sealing ring 3 is gradually reduced and extends forward and forms compressed part 30,32 edge of rear end of the sealing ring 3
The radially outwardly projecting of the sealing ring 3 forms the second bulge loop 52；When pipeline 9 to be connected is not accessed, 30 court of the compressed part
To 3 center of the sealing ring（As shown in Figure 5）, when pipeline 9 to be connected is accessed, second bulge loop 52 is placed in described second to be held
Put in portion 42, the compressed part 30 is compressed by pipeline 9 and is placed in first holding part 41（As shown in Figure 7）.
Refer to Fig. 8 to Figure 10, in the present invention, also include that the inwall 15 along anchor ear each described 1 arranges with opening
Band saw tooth plate 11, the band saw tooth plate 11 be used for limit pipeline to be connected 9, it is on the inwall 15 of the anchor ear 1, close
Annular mounting groove 151 of the internal diameter less than the annular groove 111 is provided with the medial wall 1110 of the annular groove 111, it is described
The width of annular mounting groove 151 is matched with the width of the band saw tooth plate 11, and the band saw tooth plate 11 is placed in the ring
In shape mounting groove 151, the center of the crown of the teeth 110 on the band saw tooth plate 11 towards the band saw tooth plate 11, and
The cross section of the teeth 110 is right angled triangle, and wherein angle α is right angle；One right-angle side 61 of the right angled triangle is located at
The inwall 116 of the band saw tooth plate 11；When the anchor ear 1 fixes the coupling assembly 2 and pipeline 9 to be connected, will be described
Pipeline to be connected 9 is advanced in the anchor ear 1, and the teeth 110 on band saw tooth plate 11 in the anchor ear 1 are by pipeline to be connected 9
Outer wall is stung tightly, then screws the bolt 81/83 and nut 82/84, as the cross section of the teeth 110 is right angled triangle,
Therefore very closely, when having gases at high pressure to pass through in pipe, cross section is that the teeth 110 of right angled triangle can also be born for occlusion
Play big pressure, it is not easy to the phenomenon such as fall off；Therefore, the band saw tooth plate 11 can securely be engaged pipeline so that even
The connection of joint is more firm, close advantage.In addition, in the present invention, the band saw tooth plate 11 is integrally formed carrying
The circular plate 7 of opening, the integrally formed circular plate 7 with opening are more readily processed；Similarly, in the present invention,
For the ease of installing, the band saw tooth plate 11 can also be and is made up of the first arc 112 and the second arc 113（Refer to
Shown in Fig. 8）.
In the present invention, in order that the occlusion band connecting pipe 9 that the band saw tooth plate 11 more can be fastened, institute
State on band saw tooth plate 11 at least containing along two circular toothrow teeth 110 of the circular plate 7,110 points described of two toothrow tooth
Be not the cross section of first row teeth 114 and second row teeth 115, the first row teeth 114 and second row teeth 115 be same
To right angled triangle；In present embodiment, the teeth 110 are the first in the same direction arrangement modes（As shown in Figure 10）, and
Also include second arrangement mode in the same direction（As shown in figure 11）, arrangement in the same direction can be so that suffered power be dispersed in each row
In teeth 110, therefore it is beneficial to reinforcing pipes.Certainly, in the present invention, the horizontal stroke of the first row teeth 114 and second row teeth 115
Tangent plane can also be incorgruous right angled triangle, similarly, incorgruous and while including two ways（As shown in Figure 12,13）, point
It is not the third arrangement mode and the 4th kind of arrangement mode；In the two ways of incorgruous arrangement, when described in pipeline applying and two rows
During the horizontal pressure of teeth 110, in two toothrow teeth 110, wherein the direction of a toothrow tooth 114/115 is the direction phase with pressure
Together, the direction of a toothrow tooth 115/114 is described in teeth 115/114 in opposite direction with pressure, in opposite direction can give
The effect of one obstruction of pressure so that pipeline occlusion is more firm, therefore, third and fourth kind of arrangement mode is advantageously in pipe
The fastness of road connection；In addition, in the present invention, the teeth 110 can be the tooth of continuous teeth 110, or interruption
Tooth 110（Not shown in figure）, can also be single independent teeth 110（Not shown in figure）, in the present invention, the teeth 110
It is continuous along the band saw tooth plate 11.
In the present invention, it is preferable that the anchor ear 1 is by two corresponding half anchor ears 12 of the first arc and the second arc half
Anchor ear 13 is constituted, in order to more quickly and easily connect into first arc, half anchor ear 12 and half anchor ear 13 of the second arc
Integrally, first arc, half anchor ear 12 be respectively arranged at two ends with to first arc, half anchor ear 12 radial outside extend
