Each anchor ear 1 then is fixed on after connecting pipe 9 is connect and the straight-through connection component 24 and waits for connecting pipe by part 24
First bulge loop 51 of 9 joint, the straight-through connection component 24 is embedded in the annular groove 111, at this point, the annular is recessed
The second holding part 42 is formed between the madial wall 1110 of slot 111 and the port 221 of the sticking part 22, the sealing ring 3 is placed in
In second holding part 42, in this way, each sealing ring 3 be all placed in second holding part 42 and with the sticking part
22 port 221 fits closely；In the present invention, the anchor ear 1 is so that the straight-through connection component 24 and wait between connecting pipe 9
Connection it is more secured, moreover, to be placed in each anchor ear 1 total with the straight-through connection component 24 for each sealing ring 3
With in the second holding part 42 formed, in this manner it is possible to so that the straight-through connection component 24 and wait for close between connecting pipe 9
Envelope property is more preferable；Moreover, the connection needed at turning and divided fluid stream etc. for pipeline, it is only necessary to by straight-through connection component 24
It is replaced with elbow connection component 25 and three-way connecting module 26, the anchor ear 1 of use is convenient for disassembly and assembly so that the present invention is non-
Often for ease of maintenaince and safeguard.
In order to further strengthen sealing effect, while the sealing ring 3 being made more to be firmly fixed at described second and hold
It sets in portion 42, is equipped with the first certain gap 43 between first bulge loop 51 and the outer wall 220 of the sticking part 22, described the
Two holding parts 42 are communicated with first gap 43, and second bulge loop 52 is bent to 30 direction of the compressed part, formation and institute
State the embedded division 301 of 43 corresponding matching of the first gap；When installing connector, the embedded division 301 of the sealing ring is placed in described
In first gap 43.
In order to enable the straight-through connection component 24 and wait for that the connection between connecting pipe 9 is even closer, it is each described close
31 internal diameter of front end of seal 3 is gradually reduced and extends to form forward compressed part 30, and the rear end 32 of the sealing ring 3 is along the sealing
The radially outwardly projecting of circle 3 forms the second bulge loop 52；When not accessing when connecting pipe 9, the compressed part 30 is towards described close
3 center of seal (as shown in Figure 5), when access is when connecting pipe 9, second bulge loop 52 is placed in second holding part 42
Interior, the compressed part 30 is placed in by the compression of pipeline 9 in first holding part 41 (as shown in Figure 7).
Band saw tooth plate 11 waits for connecting pipe 9 for limiting, recessed close to the annular on the inner wall 15 of the anchor ear 1
The annular mounting groove 151 that internal diameter is less than the annular groove 111, the annular mounting groove are equipped at the madial wall 1110 of slot 111
151 width matches with the width of the band saw tooth plate 11, and the band saw tooth plate 11 is placed in the annular mounting groove 151
Interior, the crowns of the teeth 110 on the band saw tooth plate 11 is towards the center of the band saw tooth plate 11, and the teeth 110
Cross section be right angled triangle, wherein angle α is right angle；One right-angle side 61 of the right angled triangle is located at the circular saw
The inner wall 116 of plate 11；When the anchor ear 1 fixes the connection component 2 and when connecting pipe 9, waits for that connecting pipe 9 pushes away by described
Into in the anchor ear 1, the teeth 110 on band saw tooth plate 11 in the anchor ear 1 will wait for that 9 outer wall of connecting pipe is stung tightly, then revolve
The tight bolt 81/83 and nut 82/84, since the cross section of the teeth 110 is right angled triangle, occlusion is very tight
It is close, when have in pipe high pressure gas by when, cross section, which is the teeth 110 of right angled triangle, can also bear up big pressure, not allow
Phenomena such as easily falling off；Therefore, the band saw tooth plate 11 can securely be engaged pipeline so that the connection of connector is more
Securely, close advantage.In addition, in the present invention, the band saw tooth plate 11 is the integrally formed circular plate with opening
7, the integrally formed circular plate 7 with opening is more readily processed；Similarly, in the present invention, for the ease of installation, institute
It states band saw tooth plate 11 and can also be and be made of (in detail as shown in Figure 8) the first arc panel 112 and the second arc panel 113.
In order to enable the occlusion band connection pipeline 9 that the band saw tooth plate 11 can be fastened more, the band saw
At least contain on tooth plate 11 along the circular two rows of teeth 110 of the circular plate 7, two rows of teeth 110 are first respectively
The cross section of toothrow tooth 114 and second row teeth 115, the first row teeth 114 and second row teeth 115 is right angle in the same direction
Triangle；In present embodiment, the teeth 110 are the first arrangement modes (as shown in Figure 10) in the same direction, and are also wrapped in the same direction
Second of arrangement mode (as shown in figure 11) is included, arrangement in the same direction can make suffered power be dispersed in every a row of teeth 110
On, therefore conducive to reinforcing pipeline.Certainly, in the present invention, the cross section of the first row teeth 114 and second row teeth 115 is also
Can be incorgruous right angled triangle, it is similarly, incorgruous and include simultaneously two ways (as shown in Figure 12,13), it is the respectively
Three kinds of arrangement modes and the 4th kind of arrangement mode；In the two ways of incorgruous arrangement, when pipeline applies and two rows of teeth 110
When the pressure of transverse direction, in two rows of teeth 110, the direction of wherein a row of teeth 114/115 is a, toothrow identical as the direction of pressure
The direction of tooth 115/114 is the direction with pressure on the contrary, the opposite teeth 115/114 in direction can give the pressure one resistance
The effect hindered so that pipeline occlusion is more secured, and therefore, third and fourth kind of arrangement mode is more conducive to the jail of pipeline connection
Solidity；In addition, in the present invention, the teeth 110 can be continuous teeth 110, can also be intermittent teeth 110 (in figure
It is not shown), it can also be 110 (not shown) of single independent teeth, in of the invention, the teeth 110 are along the ring
Shape gullet plate 11 is continuous.
