Background technique
In the existing technology; It with the linkage structure of steel pipe is automobile oil pipe in assembling: one of the termination welding that is connected at steel pipe becomes T-joint; The one-tenth T-joint of steel pipe is inserted in the sebific duct; And adopting a metallic sheath that sebific duct is locked on the steel pipe, above-mentioned one-tenth T-joint and metallic sheath all form through the metal machining.In this assembly process, complicated, many, the waste of material of manufacturing procedure of assembling linkage structure, thus increased the cost that assembles.
Improvement as said structure; Annular protrusion of connection end moulding at steel pipe is with sebific duct in the outside of annular protrusion section, and the sebific duct outer installment that is enclosed within the annular protrusion section has metallic sheath; And the both sides of the corresponding steel pipe annular protrusion of metallic sheath are provided with contraction flow region; Sebific duct is locked on the steel pipe, and wherein, metallic sheath adopts stamping forming mode.This assembly structure can solve problems such as oil pipe assembling linkage structure complicacy, waste material, manufacturing procedure are many, increase cost of production.
But for the part vehicle, the pressure in its oil pipe is higher, and is bigger to the impact of oil pipe joint, thereby the sealability of oil pipe joint is had higher requirement.Above-mentioned improved oil pipe Placement, for the applied environment of high pressure, elevated operating temperature, its sealability and functional reliability still can not satisfy the demands.Therefore, design oil pipe assembling linkage structure,, become those skilled in the art assistant officer's technical problem to be solved to satisfy application demand with high pressure or hyperpressure impact with excellent sealing performance and functional reliability.
The model utility content
To above defective, the purpose of the utility model is to provide a kind of assembling linkage structure, and it has the higher pressure that bears, and sealability and functional reliability are superior.
To achieve these goals, the technological scheme of the utility model is following:
A kind of assembling linkage structure; Comprise steel pipe 1; Metallic sheath 2 and sebific duct 3 are provided with first annular protrusion 4 in the end of steel pipe 1, inwardly be disposed with second annular protrusion 5 and annular retaining ring 6 by the end; Metallic sheath 2 is set in the periphery of steel pipe 1; And its reduced diameter portion places between second annular protrusion 5 and the annular retaining ring 6, and sebific duct 3 is between steel pipe 1 and the metallic sheath 2 and is sheathed on first annular protrusion 4 and the periphery of 5 sections of second annular protrusions, with metallic sheath 3 compression fit 4 sections of two annular protrusions of steel pipe 1 to realize that steel pipe 1 is connected with the assembling of sebific duct 3.
Preferably, the reduced diameter portion compression fit of metallic sheath 3 is 6 sections of second annular protrusion 5 to the annular retaining rings of steel pipe 1.
Compared with prior art, the utlity model has following beneficial effect:
In the utility model; Glue pipe socket is located at two annular protrusion sections of steel pipe, and is provided with metallic sheath in the outer race of the sebific duct of two annular protrusion sections, and extends to the annular retaining ring place; The metallic sheath compression fit realizes that in first annular protrusion to the annular retaining ring section of steel pipe steel pipe is connected with the assembling of sebific duct; Like this, between steel pipe and the sebific duct and the pulling-out force that is connected between metallic sheath and the steel pipe increase, increased a seal point in terms of existing technologies between steel pipe and the sebific duct; The reliability of connection is strengthened greatly, thereby can adapt to higher pressure and wideer temperature range.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
A kind of structural representation that assembles linkage structure that Fig. 1 proposes for the utility model.
A kind of generalized section of assembling linkage structure that Fig. 2 proposes for the utility model.
Reference character: 1, steel pipe; 2, metallic sheath; 3, sebific duct; 4, the first annular protrusions; 5, the second annular protrusions; 6, annular retaining ring.
Embodiment
Be illustrated in figure 1 as a kind of structural representation that assembles linkage structure that the utility model embodiment proposes, a kind of generalized section of assembling linkage structure that Fig. 2 proposes for the utility model embodiment.
With reference to accompanying drawing; A kind of assembling linkage structure that the utility model proposes comprises steel pipe 1, metallic sheath 2 and sebific duct 3; Be provided with first annular protrusion 4 in the end of steel pipe 1; Inwardly be disposed with second annular protrusion 5 and annular retaining ring 6 by the end, metallic sheath 2 is set in the periphery of steel pipe 1, and its reduced diameter portion places between second annular protrusion 5 and the annular retaining ring 6; Sebific duct 3 is between steel pipe 1 and the metallic sheath 2 and is sheathed on first annular protrusion 4 and the periphery of 5 sections of second annular protrusions, with metallic sheath 2 compression fit 4 sections of two annular protrusions of steel pipe 1 to realize that steel pipe 1 is connected with the assembling of sebific duct 3.Preferably, the reduced diameter portion compression fit of metallic sheath 2 is 6 sections of second annular protrusion 5 to the annular retaining rings of steel pipe 1.
Need to prove that the appeal metallic sheath can divide not two-part, wherein the less part of internal diameter is a reduced diameter portion, and it is set between second annular protrusion to the annular retaining ring of steel pipe, and reduced diameter portion cooperates with steel pipe like this; And the bigger part of internal diameter is set between first annular protrusion and second annular protrusion of steel pipe; Sebific duct is arranged between steel pipe and the metallic sheath and is sheathed on first annular protrusion and the periphery of the second annular protrusion section, realizes that through steel pipe is radially locked steel pipe is connected with the assembling of sebific duct.Wherein, first annular protrusion of steel pipe, second annular protrusion and annular retaining ring structure can form through the shaping die extruding.
In concrete application process, can be connected with assembling between the sebific duct with the realization steel pipe through following operation.As shown in Figure 2; At first metallic sheath 2 is enclosed within on the steel pipe 1; Metallic sheath 2 withstands on annular retaining ring 6 places; This moment metallic sheath the reducing position between second annular protrusion 5 and annular retaining ring 6, be inserted into sebific duct 35 sections of first annular protrusion 4 and second annular protrusions of steel pipe again, the front end of sebific duct 3 pushes up the reduced diameter portion of metallic sheath 2.
Like this, the outer surface of the metallic sheath 2 of 5 sections of first annular protrusion 4 and second annular protrusions is radially locked, form contraction flow region, then metal steel pipe 1 links together with sebific duct 3 very securely, and sebific duct 3 is blocked by two annular portions of steel pipe 1, and difficult quilt pulls.In addition, the outer surface of the metallic sheath 2 between second annular protrusion 5 and the annular retaining ring 6 is radially locked, make it tightly encase steel pipe 1, blocked by second annular protrusion 5 of steel pipe 1 simultaneously, difficult quilt pulls.
When metallic sheath 2 is radially locked; During near second annular protrusion 5 of steel pipe 1 sebific duct 3 pressurizeds, sizing material will extend forward, has been full of the gap between metallic sheath 2 and the steel pipe 1; Strengthen sealing greatly, thereby can adapt to higher pressure and wideer temperature range.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technological scheme is carried out; Or the design of the utility model and technological scheme are directly applied to other occasion without improving, all in the protection domain of the utility model.
