In the outer tube wall of the second sampling pipe 20.So, branch sleeve 40 and first sampling pipe 10, the second sampling pipe 20 are not only strengthened
Bonding strength.Due also to the deflation sealing function at the both ends of resilient sleeve 30, makes the sampling pipe 10 or the second of branch sleeve 40 and first
When the connection of sampling pipe 20 loosens, extraneous air can not enter sample lines by loosening position, strengthen connection
The degree of protection at place.
In the present embodiment in order to have the function that to tighten sealing and reinforce connection, preferentially from cold shrink tube (in figure not
Draw).Cold shrink tube includes shrinkage sheath (not drawn in figure) (equivalent to the resilient sleeve 30 in the present embodiment) and is built in described
Support tube (not drawn in figure) in shrinkage sheath.Shrinkage sheath and support tube energy axial separation.Both ends are connected with the first sampling
After the branch sleeve 40 of the sampling pipe 20 of pipe 10 and second is built in support tube, the plastics drawing for being arranged on support tube one end is pulled with hand
Button, support tube are separated with shrinkage sheath, and shrinkage sheath tightens and is coated at outer tube wall and the first sampling of branch sleeve 40
On the outer tube wall of the sampling pipe 20 of pipe 10 and second.
The outer tube wall of the inner tube wall of first spring cylinder section 311 and the first sampling pipe 10 is mutually brought into close contact, the first sampling pipe 10
Outer tube wall be located at part in the first spring cylinder section 311 towards outer lug, form first annular raised 11.3rd spring cylinder section
The outer tube wall of 312 inwall and the second sampling pipe 20 is mutually brought into close contact, and the outer tube wall of the second sampling pipe 20 is located at the 3rd spring cylinder
Part in section 312 forms the second annular protrusion 21 towards outer lug.Specifically, first annular raised 11 and second annular protrusion
21 shape can be ratchet-like.In the present embodiment ratchet-like first annular raised 11 and second annular protrusion 21 quantity
It is one, multiple first annular raised 11 and second annular protrusion 21 can be arranged as required in other embodiments.
First annular raised 11 and second annular protrusion 21 not only add resilient sleeve 30 in the first sampling pipe 10 and
Sealing area at the both ends of two sampling pipe 20, lift-off seal degree of protection, also the both ends of resilient sleeve 30 are caused to be not susceptible to phase
To axial shrinkage.So as to which, extraneous air can not be from the contact surface of the first spring cylinder section 311 and the first sampling pipe 10 and the
Pass through between the contact surface of three spring cylinder sections 312 and the second sampling pipe 20.
Branch sleeve 40 between the first spring cylinder section 311 and the 3rd spring cylinder section 312, the both ends of branch sleeve 40
End face offers the first lead-in chamfered 41 and the second lead-in chamfered 42 respectively.Specifically, away from the second sampling on branch sleeve 40
The end face of pipe 20 is offered for guiding the first sampling pipe 10 to insert and the first lead-in chamfered 41 of the setting that slopes inwardly.Adapter sleeve
On cylinder 40 away from the end face of the first sampling pipe 10 offer for guide the second 20 pipes of sampling insert and the setting that slopes inwardly the
Two lead-in chamfereds 42.First uses pipe 10 fast and accurately to insert branch sleeve 40 under the guiding of the first lead-in chamfered 41
It is interior；Second using pipe 20 under the guiding of the second lead-in chamfered 42, can fast and accurately insert in branch sleeve 40, so can be with
Improve the installation effectiveness of the first sampling pipe 10 and the second sampling pipe 20.
The inner tube wall of the outer tube wall of branch sleeve 40 and the second resilient sleeve 313 is mutually brought into close contact.Specifically, the second elasticity
The inner tube wall of sleeve 313 is applied with pressure to the outer tube wall of branch sleeve 40, branch sleeve 40 and the first sampling pipe 10 or is connected
When the sampling pipe 20 of sleeve 40 and second relatively rotates, it will be constrained by the inwall of the second spring cylinder section 313, so as to avoid
Connection between the sampling pipe 10 of branch sleeve 40 and first and the sampling pipe 20 of branch sleeve 40 and second occurs to loosen and come off,
Reach the effect for reinforcing connection, usual bonding strength is up to 50Kgf.
First sampling pipe 10 be located at outer tube wall in the first spring cylinder section 311, the first spring cylinder section 311 inner tube wall and
First lead-in chamfered 41 surrounds to form first annular annular seal space 50 jointly.Because extraneous air can not pass through the first spring cylinder section
311 and the first contact surface between sampling pipe 10, enter in first annular annular seal space 50, so as in first annular annular seal space 50
Air also cannot be introduced into the first sampling pipe 10.So, even if pine occurs for the connection of the sampling pipe 10 of branch sleeve 40 and first
Dynamic, extraneous air will not also impact to result of detection, avoid the decline or forfeiture of equipment detecting function.
Second sampling pipe 20 be located at outer tube wall in the 3rd spring cylinder section 312, the 3rd spring cylinder section 312 inner tube wall and
Second lead-in chamfered 42 surrounds to form the second annular seal space 60 jointly.Extraneous air can not pass through the 3rd spring cylinder section 312
With the contact surface between the second sampling pipe 20, enter in the second annular seal space 60, so as in the second annular seal space 60
Air also cannot be introduced into the second sampling pipe 20.So, even if the connection of branch sleeve 40 and the second sampling pipe 20 loosens,
Outside air will not also impact to result of detection.So, the degree of protection of branch sleeve 40 is not only strengthened, it is thus also avoided that
The decline or forfeiture of equipment detecting function.
The utility model embodiment additionally provides a kind of aspirated smoke detection device (not drawn in figure), the air suction type cigarette
The sample lines of mist detection device include above-mentioned pipeline connection component 100.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
