The structural integrity of pipe；The setting of enhancement layer and protective layer can also effectively improve the mechanicalness of the utility model fuel hose
Energy.Further, in the utility model, the multilayer by setting inner glue layer, mesoglea, outer glue-line, enhancement layer and protective layer is multiple
Close structure, available a kind of have good structural integrity and with good low temperature resistant, high temperature resistant, high-barrier and low
The fuel hose of permeance property.
Utility model content
The utility model provides a kind of smooth surface rubber hose, solves that oil delivery hose is wear-resisting, texture is smooth and anti-negative pressure
Technical problem extends the service life of oil delivery hose, improves the safety of oil delivery hose.
A kind of smooth surface rubber hose, including tube body and buckle press joint, buckle press joint are mounted in a port of tube body,
It is characterized in that, tube body includes the mesoglea between inner glue layer and outer glue-line and inner glue layer and outer glue-line, mesoglea and outer glue-line
Between be wirerope-winding formed enhancement layer, between mesoglea and inner glue layer be also wirerope-winding formed enhancement layer, outside
The outside of glue-line coats the smooth layer formed by polypropylene.
The utility model has the beneficial effects that extend the service life of oil delivery hose, improve oil delivery hose texture and
Anti- negative pressure performance, improves the safety of oil delivery hose, coats one layer of smooth layer for having polypropylene to be made into the outside of outer glue-line,
The wear-resisting property for not only improving oil delivery hose, is also formed with the smooth layer of texture, prolongs the service life, and increases aesthetic feeling.In addition, two
Layer enhancement layer structure, not only protects oil delivery hose inner glue layer, but also improve the integral firmness of oil delivery hose, makes oil delivery hose
With good anti-negative pressure ability.
The buckle press joint includes the interconnecting piece for connecting oil delivery hose, and interconnecting piece is formed by withholding set and inner core, withholds set
It is fixed on inner core outer peripheral surface, withholds to be formed between set and inner core and accommodate oil delivery hose wall and withhold slot.
Described withhold forms annular flange on set inner wall, and arcuate bottom is formed on the bottom for withholding slot.
Annular lateral dimension is formed on the inner peripheral surface of the annular flange is less than the sub convex of flange inner peripheral surface face lateral dimension
Edge.
The quil of several annular arrays is also set up on the inner wall for withholding set, the tip inclination direction of quil withholds slot
Bottom.
Two annular hoops are set on the outer peripheral surface for withholding set, two hoops respectively with annular flange and annular array
Quil is corresponding.
The tail end for withholding set forms the opotism structure turned up.
Buckle press joint has the function of good leakproofness and firm fixation sebific duct, is such as withholding setting annular inside set
It is lesser that lateral dimension is arranged in flange, extruding oil pipeline wall that can be closer especially on the inner peripheral surface of annular flange
Sub- flange, sub- flange can be smoothly embedded in oil pipeline wall, form better seal effect.
It is also set up on the inner wall for withhold set to the inclined several quils of trench bottom are withheld, quil is pierced into oil pipeline wall
It is interior, prevent oil pipeline wall from falling off.Opotism structure plays a protective role, and prevents the outer wall of oil pipeline from wearing.Slot is withheld to be formed
Arcuate bottom avoids bottom stress concentration from causing to be broken.
It elaborates with reference to the accompanying drawings and examples to the utility model.
Detailed description of the invention
Fig. 1 is the structural scheme of mechanism of the utility model.
Fig. 2 is the oil delivery hose wall of the utility model and the connection structure diagram of buckle press joint.
Fig. 3 is the cross-sectional view of buckle press joint.
The cross-sectional view of another embodiment of the room Fig. 4 buckle press joint.
Appended drawing reference
1 tube body, 101 inner glue layers, 102 enhancement layers, 103 mesoglea, 104 enhancement layers, 105 outer glue-lines,
106 smooth layers, 201 opotism structures, 202 hoops, 203 withhold set, and 204 bind round, 205 inner cores,
206 annular flanges, 207 sub- flanges, 208 quils, 209 withhold slot.
Specific embodiment
Such as Fig. 1, mesoglea 103 is between outer glue-line 105 and inner glue layer 101, and in mesoglea 103 and inner glue layer 101
Between lay enhancement layer 102.Enhancement layer 104 is laid between mesoglea 103 and outer glue-line 105.It is coated in the outside of outer glue-line 105
