Abstract
The utility model discloses a buckle press joint of an oil cooling tube core tube for an automobile, which is provided with a cylindrical faying face structure. A chamfer is arranged at the end of the cylindrical faying face, the cylindrical faying face is provided with a groove with the section in a rectangular shape or a trapezoidal shape. The buckle press joint of the oil cooling tube core tube for the automobile has the advantages that by arranging the chamfer at the end of the cylindrical faying face of the buckle press joint of the core tube and arranging the groove on the cylindrical faying face, the assembling process of products can be achieved more easily, pull-out force resistance of the assembled products is improved, and permeability resistance and durability of the products are enhanced.
Description
Technical field
The utility model relates to the joint of withholding of the cold tube core pipe of a kind of gasoline, is used for being connected of the cold tube core pipe of gasoline and flexible pipe.
Background technique
Along with the raising that automotive performance is required with people of popularizing of automobile, require also improving constantly for the permeability resistance of automobile cooling system.People constantly research and develop new, better rational oil-cooled tube hose construction on the one hand at present, on the other hand the flexible pipe of oil-cooled tube and the Placement of core pipe are also improved continuous the improvement.The existing core pipe thread crimp head form that generally adopts is the single-drum packet form, when the core Guan Zaiyu flexible pipe of this form connects, exists assembling difficulty or permeability resistance to differ from two aspect defectives.
The model utility content
The utility model technical problem to be solved is to this two aspects defective of existing technology, provides a kind of and can satisfy the requirement of product permeability resistance, can satisfy the head of withholding of the cold tube core pipe of gasoline of producing the assembling needs again.
For solving the problems of the technologies described above; The technological scheme that the utility model is taked is: the cold tube core pipe of a kind of gasoline withhold joint; The said joint of withholding has cylinder junction plane structure; End at said cylinder junction plane is provided with chamfering, and on said cylinder junction plane, being provided with sectional shape is rectangle or trapezoidal groove.
Said chamfering is taper or semicircle.
The quantity of said groove is more than 1.
When the oil cooling tube core pipe that utilizes said structure to withhold joint is connected with flexible pipe; At first will overlap with core pipe thread crimp head and carry out riveted; Then flexible pipe is inserted between core pipe thread crimp head and the cover, re-use certain pressure withhold joint, cover and the flexible pipe of core pipe carried out riveted at the groove position of the cylinder junction plane of withholding joint.
Adopt the beneficial effect that technique scheme produced to be: (1) is provided with chamfering through the end of withholding joint cylinder junction plane at oil cooling tube core pipe; Make the area of contact of core body and hose inner wall reduce; Thereby reduced the insertion force when product assembles, satisfied the assembling needs of product.
(2) be rectangle or trapezoidal groove through on oil cooling tube core pipe thread crimp head cylinder junction plane, sectional shape being set, form close toothing, the anti-pulling-out force of the product that makes core pipe and flexible pipe assemble improves; Core pipe with the close toothing of this kind is applicable to the oil-cooled tube flexible pipe that internal diameter is less, wall thickness is thin; Like the flexible pipe of φ 9.5 specifications, when flexible pipe and the assembling of core pipe, only need flexible pipe to fall into into groove on a small quantity like this, flexible pipe is produced than large deformation; Thereby can not produce damage to flexible pipe yet; Can guarantee the stablizing effect that connects equally, flexible pipe pull and sealing effect can not be affected, strengthened the permeability resistance and the durability of product.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Wherein, 1, chamfering, 2, groove.
Embodiment
As shown in Figure 1, the cold tube core pipe of the described gasoline of the utility model withhold joint, it has cylinder junction plane structure, is provided with chamfering 1 in the end of cylinder junction plane, on the cylinder junction plane, being provided with sectional shape is rectangle or trapezoidal groove 2.
The shape of above-mentioned chamfering 1 can be taper or semicircle.
The quantity of above-mentioned groove 2 is more than 1.
When the oil cooling tube core pipe that utilizes said structure to withhold joint is connected with flexible pipe; At first will overlap with core pipe thread crimp head and carry out riveted; Then flexible pipe is inserted between core pipe thread crimp head and the cover, re-use certain pressure withhold joint, cover and the flexible pipe of core pipe carried out riveted at the groove position of the cylinder junction plane of withholding joint.
The sectional dimension and the flexible pipe of above-mentioned core pipe thread crimp head cylinder junction plane carry out interference fit, guarantee the permeability resistance of product.
In sum; The utility model is provided with chamfering through the end of withholding joint cylinder junction plane at the core pipe, and on the cylinder junction plane, groove is set, and makes the product assembly process realize more easily; And the anti-pulling-out force of the product that has assembled improves, and has strengthened the permeability resistance and the durability of product.
Claims (3)
1. the cold tube core pipe of gasoline withholds joint; It is characterized in that; The said joint of withholding has cylinder junction plane structure, is provided with chamfering (1) in the end of said cylinder junction plane, and on said cylinder junction plane, being provided with sectional shape is rectangle or trapezoidal groove (2).
2. the cold tube core pipe of gasoline according to claim 1 withhold joint, it is characterized in that said chamfering (1) is taper or semicircle.
3. the cold tube core pipe of gasoline according to claim 2 withhold joint, it is characterized in that the quantity of said groove (2) is more than 1.
