Specific embodiment
For the content for further appreciating that the utility model, the utility model is described in detail in conjunction with attached drawing.
Embodiment 1
A kind of pipelines of automobile air conditioner connector of the present embodiment, as shown in Figure 1, Figure 2 and Figure 3, comprising:
Pipe connects end 1, is used to access access tube 5 and fix；
Be spirally connected end 2, is fixedly connected on pipe and connects 1 one end of end, outer wall is tapped；
Through hole 3, perforation setting connect end 1 and are spirally connected in the middle part of 2 end faces of end in pipe；
Further include:
Limiting stand 30, is the convex annular eaves being arranged on through hole 3, and internal diameter is less than 5 outer diameter of access tube；
Diversion trench 31 is the annular groove being arranged on through hole 3, is located at limiting stand 30 and 5 contact position of access tube
Side.
In automotive air-conditioning system, there is the pipeline structure of many complexity, some pipelines are in the demand of heat exchange efficiency, using aluminium
Pipe, for aluminum pipe when connecting between carrying out pipe, the method for mechanical connection is sometimes and unreliable, needs to use welding method, however due to
The unconventional shape of some joints, operating difficulties and welding effect and bad when directly being welded, therefore, it is necessary to design one
Kind facilitate the connector of the piping connection of welding, existing welding point usually connects end 1 by pipe, be spirally connected end 2 and through tube connects end 1
It forms with the through hole 3 in the middle part of 2 end faces of end that are spirally connected, when in use first connects access tube 5 from the through hole 3 that pipe connects 1 end face of end
Enter, the diameter that access tube 5 accesses part through hole 3 is slightly larger than 5 outer diameter of access tube, so that access tube 5 smoothly accesses, then fixes
Firmly access tube 5 start to weld along the gap that access tube 5 connects end 1 with pipe, and after being welded, the end 2 that is spirally connected carries out spiral shell with connecting component
Line connection, as is illustrated by figs. 11 and 12, access tube 5 can there is following problems in welding: fusion welding along access tube 5 with
Gap between through hole 3 is flowed into connector, and after flowing to the end face of access tube 5, fusion welding will continue to flow, and is being penetrated through
The surrounding of 3 inner wall of hole is accumulated, when serious may blocking pipeline patency, influence air-conditioning system normal operation.In response to this problem,
The present embodiment is made that improvement to pipe joint:
On 3 inner wall of through hole be arranged limiting stand 30, limiting stand 30 be arranged in through hole 3 pipe connect hold 1 part ring
The convex eaves of shape, internal diameter are less than 5 outer diameter of access tube, and effect is the access depth for limiting access tube 5 and connecing end 1 in pipe, 5 access tube of access tube
After connecing end 1, end face is connected on limiting stand 30, is welded at this time, when end face abuts good with limiting stand 30 (by access tube
5 are compacted on limiting stand 30), the solder of melting is not easy to continue to leak into through hole 3, still after flowing to limiting stand 30
Access tube 5 is compacted on limiting stand 30 by the moment when being difficult to ensure welding, there is also leakage scenarios sometimes, in view of this, to pipe
Pipeline connector makes further improvement；
On limiting stand 30 and the through hole 3 of the surrounding of 5 contact portion of access tube, it is provided with diversion trench 31, in a ring groove
Shape, when fused materials flow to the contact portion of limiting stand 30 and access tube 5, since space is greater than contact portion at diversion trench 31
The space in gap, therefore, fused materials can preferentially flow to diversion trench 31, thereby it is ensured that after welding pipeline patency.
Further, diversion trench 31 can be provided with certain gradient along gravity direction, to enhance drainage effect.
The pipelines of automobile air conditioner of the present embodiment uses steel pipe fitting with connector.
Embodiment 2
A kind of pipelines of automobile air conditioner connector of the present embodiment, is further improved on the basis of embodiment 1, as Fig. 4,
Shown in Fig. 5 and Fig. 6,1 end face Guan Jieduan and 3 intersection of through hole are provided with draining hole 32.Draining hole 32 is opened up along intersection
One ring shape groove, in the present embodiment, bevel angle is 45 °, and when being welded, this draining hole 32 can draw fusion welding
It flows into the gap between access tube 5 and through hole 3, and after the completion of welding, the weld shape that weld surface is formed
More regular, the comparison of weld shape, which can be seen that, from Fig. 6 and Figure 12 makes welding procedure more specification beauty.
Embodiment 3
A kind of pipelines of automobile air conditioner connector of the present embodiment, is further improved, such as on the basis of embodiment 1 or 2
Further including draining ring 4 shown in Fig. 7 and Fig. 8, be outer ring surface 40 is smoothed curve, internal diameter is equal to the annulus of 5 outer diameter of access tube,
It is placed on limiting stand 30.The outer face of one end without leave of draining ring 4 uniformly increases to other end, and access tube 5 passes through the interior of draining ring 4
It is abutted to after loop section on limiting stand 30, the outer wall and 4 outer ring surface 40 of draining ring of access tube 5 seamlessly transit, when fused materials edge
When 5 tube wall of access tube is flow at draining ring 4, the curved surface to be smoothly transitted is drained to diversion trench 31, further ensures that fused materials
It is unobstructed that channel interior influence pipeline will not be entered.
Embodiment 4
A kind of pipelines of automobile air conditioner connector of the present embodiment, is further improved, such as Fig. 9 on the basis of embodiment 3
With shown in Figure 10,4 bottom end of draining ring is fixedly connected with position-limiting drum 41, and the cylinder of 30 internal diameter of limiting stand is equal to for outer diameter.
It is fixedly connected with position-limiting drum 41 in the big end face of 4 outer diameter of draining ring, 41 barrel of position-limiting drum is thin-walled, wall thickness in the present embodiment
For 2mm, it is subject to the direct motion for not influencing fluid in access tube 5.Draining ring 4 can be positioned to limiting stand 30 and hit exactly position by position-limiting drum 41
It sets, so that the access tube 5 for passing through draining ring 4 is fixed on 30 center position of limiting stand, at this point, 5 tube wall of access tube and through hole 3
Between clearance position it is uniform, the even intensity of tube wall surrounding after welding, sealing uniformly, improve welding quality and welding the longevity
Life.
Embodiment 5
A kind of pipelines of automobile air conditioner connector of the present embodiment, further changes on the basis of embodiment 1 or 2 or 3 or 4
Into it is hexagon that the pipe, which connects 1 outer wall of end,.Pipe connects 1 outer wall shape of end with the shape of hex bolts bolt head, when access tube 5 welds
After connecting, end 2 is spirally connected when connecting corresponding position, and convenient wrench clamping pipe connects 1 outer wall of end and is spirally connected.
Embodiment 6
A kind of pipelines of automobile air conditioner connector of the present embodiment, makees on the basis of embodiment 1 or 2 or 3 or 4 or 5 into one
Step is improved, and is connect 33 diameters of changeover portion of end 1 and the 2 junction through holes 3 of end that are spirally connected positioned at pipe and is connect end 1 to being spirally connected end 2 gradually from pipe
Increase.After fluid enters through hole 3 of connector from access tube 5, it is gradually increased along the diameter of fluid direction of motion through hole 3
It keeps stablizing after a distance, so that fluid can be buffered after entering through hole 3 in this changeover portion 33, flow velocity is subtracted
It is small, reduce fluid to the impact load at piping connection position, extends the service life at piping connection position.
