Abstract
A kind of oil-cooled tube withholds jointing structure, including lining core and withholds set, and the lining core is metal tube, is withheld in set through withholding the mounting hole that set sets and being inserted into, and the end of the lining core is taper type.The lining core is divided into positioned at the inner segment withheld in set and positioned at the outer section withheld outside set.Multiple annular grooves are arranged at intervals with the inner of the lining core, bulge loop is formed between adjacent annular groove, the edge of bulge loop outer surface both sides is circular arc.The lining core outer wall sets restraining position ring block, and the spacing ring is abutted in withhold and covered on the inwall of mounting hole outer rim.Oil-cooled tube is withheld jointing structure and the interior glue of AEM sebific ducts mitigation deformation rear enclosure can be attached in lining core, and the concaveconvex structure that the annular groove in lining core is formed makes the interior glue of AEM sebific ducts deform therewith, enters into annular groove, and be closely attached on bulge loop outer wall.Concaveconvex structure in lining core is more gentle, big with glue contact area in sebific duct, and edge sets arc transition, can not only prevent glue in sebific duct from crushing, while more frictional force can be produced, increases pulling-out force, improves sebific duct stability maintenance.
Description
Technical field
The utility model is related to a kind of sebific duct connecting assembly part, is that a kind of oil-cooled tube withholds jointing specifically
Structure.
Background technology
In the oil cooling pipeline of automobile, AEM sebific duct performances are higher than other properties of rubber, and especially high temperature resistant can reach
150 °, but its particularity has drawback again, and when being connected with metal tube riveted, interior glue is frangible, must ensure pulling-out force, prevents glue
Pipe is deviate from from joint.Current sebific duct buckle press joint is provided with jagged groove as the metal tube that bushing is used, and is using AEM
When sebific duct makes oil cooling pipe assembly, inner glue layer is more prone to generation and crushes, and draws towing force to decline, and product quality is difficult to ensure that.
Utility model content
The utility model cannot adapt to the requirement of AEM sebific ducts for current sebific duct mouthful crimp head, and existing easily makes AEM glue
The problem of glue rupture in pipe, proposes that a kind of oil-cooled tube withholds jointing structure.
Oil-cooled tube of the present utility model withholds jointing structure, including lining core and withholds set, and the lining core is metal tube,
It is inserted into through the mounting hole for withholding set setting and is withheld in set, the end of the lining core is taper type.
The lining core is divided into positioned at the inner segment withheld in set and positioned at the outer section withheld outside set.
Multiple annular grooves are arranged at intervals with the inner of the lining core, bulge loop, the bulge loop appearance are formed between adjacent annular groove
The edge of face both sides is circular arc；The groove width of the annular groove is more than 1/3rd of the width of bulge loop, less than the two of bulge loop width
/ mono-；The groove depth of the annular groove is 1/5th of groove width.
The lining core outer wall sets restraining position ring block, and the spacing ring abuts in the inwall for withholding set positioned at mounting hole outer rim
On.
The beneficial effects of the utility model are：Oil-cooled tube withholds jointing structure can be relaxed the interior glue of AEM sebific ducts
Deformation rear enclosure is attached in lining core, and the concaveconvex structure that the annular groove in lining core is formed makes the interior glue of AEM sebific ducts deform therewith, enters into
In annular groove, and closely it is attached on bulge loop outer wall.Concaveconvex structure in lining core is more gentle, big with glue contact area in sebific duct, and
And edge sets arc transition, can not only prevent glue in sebific duct from crushing, while more frictional force can be produced, increase is pulled
Power, improves sebific duct stability maintenance.
Bulge loop is bigger than annular groove width, it is ensured that have sufficiently large contact area with glue in sebific duct, increases pulling-out force, while annular groove
Width and depth glue in sebific duct is farthest entered into annular groove by deformation enough, improve sebific duct and lining core
Combination degree.
Brief description of the drawings
Accompanying drawing 1 withholds the structural representation of jointing structure for oil-cooled tube；
Accompanying drawing 2 is the structural representation of bushing.
Specific embodiment
In order to be able to further appreciate that structure of the present utility model, feature and other purposes, in conjunction with appended preferred embodiment
Detailed description is as follows, and illustrated preferred embodiment is merely to illustrate the technical solution of the utility model, and non-limiting practicality
It is new.
Specific embodiment of the present utility model is as follows：
As shown in Fig. 1 to 2, oil-cooled tube withholds jointing structure including lining core 1 and withholds set 2.
Lining core 1 is metal tube, is inserted into through the mounting hole 3 for withholding the setting of set 2 and withheld in set 2, and the end of lining core 1 is cone
Platform shape.
1 point of lining core is positioned at the inner segment withheld in set 2 and positioned at the outer section withheld outside set.
Multiple annular grooves 4 are arranged at intervals with the inner segment of lining core 1, bulge loop 5, the outer surface two of bulge loop 5 are formed between adjacent annular groove 4
The edge of side is circular arc；The groove width of annular groove 4 more than bulge loop 5 width 1/3rd, less than the width of bulge loop 5 two/
One；The groove depth of annular groove 4 is 1/5th of groove width.
The outer wall of lining core 1 set restraining position ring block 6, spacing ring 6 abut in withhold set 2 be located at the outer rim of mounting hole 3 inwall on.
First lining core 1 is inserted into sebific duct 7, due to the internal diameter of the external diameter more than sebific duct 7 of lining core 1, the end of frustum makes
Lining core 1 is easily inserted.During insertion, sebific duct 7 gradually struts deformation by lining core 1, then into annular groove 4 in, further out
Annular groove 4, is strutted and rubbed with it by bulge loop 5, until by each annular groove 4 and bulge loop 5, on top to spacing ring 6.
Because the external diameter of bulge loop 5 in lining core 1 is identical with the external diameter of lining core 1, the sebific duct 6 at bulge loop 5 keeps strutting shape
State, and the sebific duct 7 at annular groove 4 is located at then because deformation bounces back and enters into annular groove 4.Bulge loop 5 is contacted with the internal face of sebific duct 6,
And interference fit, with larger frictional force, and bulge loop 5 is wider, and the contact surface with sebific duct 7 is big, and sebific duct 7 is with lining core 1
Inner segment deformation of unevenness, it is difficult to deviate from.Sebific duct 7 does not have sharp structure during inserting, and annular groove 4 is also with the intersection of bulge loop 5
Circular arc, deformation transition is gentle, and rubber tube inner wall is difficult to breakage, it is ensured that assembly quality.
The depth of annular groove 4 can allow the retraction of sebific duct 7, and cling to the bottom land of annular groove 4, support sebific duct 7, it is to avoid sebific duct
7 flexible differences are larger, prevent from being ruptured at the dilatation of sebific duct 7.
Then set 2 will be withheld to be inserted in from the other end of lining core 1, until it is pushed up onto spacing ring 6.Total is put into and is withheld
On machine, set 2 will be withheld and withhold deformation, the part for withholding the depression of set 2 is alignd with annular groove 4, and sebific duct 7 is located at into the part in annular groove 4
It is locked in annular groove 4, installation is withheld in completion.
