Abstract
The utility model discloses the attachment structure of a kind of corrugated tube and straight tube, including corrugated tube (1) and straight tube (2), the end of described straight tube (2) is provided with the inner ring-shaped step groove (2.1) extended along straight tube (2)；The end of described corrugated tube (1) is plugged in ring-shaped step groove (2.1)；The circumferential wall laminating of the outer circle wall of the end of corrugated tube (1) and step groove (2.1)；The end of straight tube (2) is welded with the outer wall of corrugated tube (1).After using this structure, it is provided that a kind of avoid the pumped (conveying) medium in pipeline directly to contact with solder joint after welding, thus improve the attachment structure of the corrugated tube corrugated tube with the service life of straight tube and straight tube.
Description
Technical field
This utility model relates to automobile pipeline technical field, specifically be the attachment structure of a kind of corrugated tube and straight tube.
Background technology
Corrugated tube often applies on automobile pipeline, in order to compensate pipeline or machine, equipment as a kind of flexible pressure-resistant pipe fitting
Connect the mutual displacement of end, absorb vibrational energy, it is possible to play the effect such as vibration damping, noise reduction, there is flexible, light weight, corrosion resistant
The multinomial features such as erosion, resisting fatigue, high-low temperature resistant.
Corrugated tube is often connected with straight tube with the use of, in prior art, corrugated tube usually welds with the connected mode of straight tube
Connecing, the solder joint after having welded directly contacts the pumped (conveying) medium in pipeline, so, will produce following deficiency: due to welding
The corrosion resistance at place, abrasion resistance are poor, in use, pumped (conveying) medium the washing away for a long time weld in pipeline, Yi Zao
Solder joint is become to come off inefficacys, reduction pipeline service life.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of avoids the pumped (conveying) medium in pipeline straight after welding
Connect and contact with solder joint, thus improve the attachment structure of the corrugated tube corrugated tube with the service life of straight tube and straight tube.
For solving the attachment structure of above-mentioned technical problem, corrugated tube of the present utility model and straight tube, including corrugated tube with straight
Pipe, the end of described straight tube is provided with the inner ring-shaped step groove extended along straight tube；The end of described corrugated tube is plugged on annular
In step groove；The circumferential wall laminating of the outer circle wall of the end of corrugated tube and step groove；Outside the end of straight tube is with corrugated tube
Wall welds.
After using above structure, this utility model compared with prior art, has the advantage that 1. owing to being provided with step
Groove, when welding, the end of corrugated tube is plugged in ring-shaped step groove, and step groove plays spacing effect, on the one hand, make welding
Technique is convenient；On the other hand, in use, support can be provided to weld, it is to avoid weld frees vibrations fatigue.The most straight
The end of pipe is welded with the outer wall of corrugated tube and the outer circle wall of end of corrugated tube is fitted with the circumferential wall of step groove, this
Sample, avoids the pumped (conveying) medium in pipeline directly to contact with solder joint, thus improves the service life of corrugated tube and straight tube after welding.
Preferably, it is provided with sealing ring between end and the ring-shaped step rooved face of described corrugated tube；Sealing ring one end and ripple
The end of stricture of vagina pipe is adjacent to, and the other end of sealing ring is adjacent to ring-shaped step rooved face.So, the conveying in pipeline is avoided further
Medium directly contacts with solder joint, thus improves the service life of corrugated tube and straight tube further.
Preferably, the end of described corrugated tube is inclined plane, and the angle α between described inclined plane and corrugated tube outer surface is
60 °～80 °.Thus it is possible, on the one hand, when ring-shaped step groove is inserted in the end of corrugated tube, play guide effect；On the other hand, incline
Inclined-plane is more preferable to the squeezing effect of sealing ring, is further ensured that sealing.
Certainly, the end of described corrugated tube can also be cancave cambered surface.As such, it is possible to sealing ring is carried out spacing.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of corrugated tube and the attachment structure of straight tube.
Fig. 2 is the schematic cross-section of corrugated tube and the attachment structure junction of straight tube.
Fig. 3 is corrugated tube and the end of corrugated tube in the attachment structure of straight tube is schematic cross-section during cancave cambered surface.
Detailed description of the invention
Utility model is described in more detail by 1 to accompanying drawing 3 and detailed description of the invention below in conjunction with the accompanying drawings.
As Fig. 1 is to shown in 2, and a kind of corrugated tube and the attachment structure of straight tube, including corrugated tube 1 and straight tube 2, its feature exists
In: the end of described straight tube 2 is provided with the inner ring-shaped step groove 2.1 extended along straight tube 2；The end grafting of described corrugated tube 1
In ring-shaped step groove 2.1；The circumferential wall laminating of the outer circle wall of the end of corrugated tube 1 and step groove 2.1；The end of straight tube 2
Portion welds with the outer wall of corrugated tube 1.Solder joint 4 is positioned at the end of straight tube 2 and the outer wall surface of corrugated tube 1.
It is provided with sealing ring 3 between end and ring-shaped step groove 2.1 surface of described corrugated tube 1；Sealing ring 3 one end and ripple
The end of pipe 1 is adjacent to, and the other end of sealing ring 3 is adjacent to ring-shaped step groove 2.1 surface.
The end of described corrugated tube 1 is inclined plane 1.1.
Angle α between described inclined plane 1.1 and corrugated tube 1 outer surface is 60 °～80 °.
Certainly, as it is shown on figure 3, the end of described corrugated tube 1 can also be cancave cambered surface 1.2.
The above, be only the most feasible enforcement example of this utility model, it is impossible to the most i.e. limit to of the present utility model
Interest field, for those skilled in the art, all utilization the technical solution of the utility model and technology design are made
Other various corresponding changes all should belong within this utility model scope of the claims.
