Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of high-pressure hose connector as shown in Figure 1, including core pipe 1 and casing 2, after hose is placed in core pipe 1, passes through button
Press is secured the hose between casing 2 and core pipe 1.
As shown in Fig. 2, core pipe 1 includes connecting the connecting portion 11 of Hydraulic Elements and the socket part for fixing hose
12.12 outer ring surface of socket part is fixedly connected with restraining position ring block 121 and retainer ring 122, and spacing ring 121 is located at retainer ring 122 with connecting
There is certain distance between portion 11 and between spacing ring 121 and retainer ring 122.Casing 2 includes snap ring 21, and snap ring 21 passes through button
Press and be caught in behind the gap between spacing ring 121 and retainer ring 122 so that casing 2 is fixed in core pipe 1 and can not opposite fortune
It is dynamic.The internal diameter of snap ring 21 is less than the diameter of spacing ring 121 so that 121 energy of spacing ring during casing 2 is withheld in core pipe 1
Enough prevent snap ring 21 from being moved towards connecting portion 11, so as to which the fixed effect between hose and core pipe 1 be avoided to be affected.
As shown in Fig. 2, for the compactness connected between reinforced hose and core pipe 1, if 2 inner ring surface of casing is fixedly connected with
Dry compression ring 22, hose deform upon after the extruding by compression ring 22 and are difficult to detach with core pipe 1.The section shape of compression ring 22
Shape for semicircle so that hose is less likely to occur to be broken after the extruding by compression ring 22, so as to avoid hose be broken after with core
What the compactness connected between pipe 1 declined happens.12 outer ring surface of socket part be provided with it is several cyclic annular and with compression ring 22
Put corresponding pressing groove 123 so that hose can be caught in pressing groove 123 after being squeezed by compression ring 22, so that hose is difficult
To be detached with core pipe 1.
As shown in Figure 2 and Figure 3, the cross sectional shape of pressing groove 123 is the top of the horn of triangle and slot bottom towards away from retainer ring
122 direction setting so that after hose is close to 123 each side wall of pressing groove, side of the side wall of pressing groove 123 far from connecting portion 11
Wall can give its opposite reaction force when hose is by active force away from the direction of connecting portion 11, so as to prevent hose
It is detached with core pipe 1.Several convex grains 3 are fixedly connected on 123 two side of pressing groove so that the friction of each side wall of pressing groove 123
Coefficient increases, so as to increase the compactness connected between hose and core pipe 1.
As shown in Fig. 2, 2 inner ring surface of casing is circumferentially fixed to be connected with several fixed cones 23,12 outer ring surface of socket part is circumferentially set
It is equipped with several with 23 corresponding cone tank 124 of fixed cone, fixed cone 23 during core pipe 1 and casing 2 are fastened by buckle machine
It is pierced into hose and increases the compactness connected between hose and core pipe 1.Since fixed cone 23 is along 2 circle distribution of casing rather than in ring
Shape, therefore fixed cone 23 will not cause the fracture of hose.Fixed cone 23 is soft so as to avoid between compression ring 22 and snap ring 21
Pipe is punctured and is be easy to cause the situation of fluid leakage by fixed cone 23.
As shown in Fig. 2, fluency during in order to increase fluid by 1 inner cavity of core pipe, the internal diameter at 1 both ends of core pipe towards outside by
It is cumulative big.Fluid from hose or Hydraulic Elements flow into 1 inner cavity of core pipe when, the inlet of fluid increases, while socket part 12 is separate
The face area of connecting portion 11 becomes smaller, and fluid transport will not be caused to hinder.
As shown in Fig. 2, side of the connecting portion 11 far from socket part 12 is provided with the seal groove 111 of annular so that connecting portion
The leakproofness connected between 11 and Hydraulic Elements greatly improves.2 inner ring surface of casing and 12 outer ring surface of socket part are coated with frosted
Metal so that the frictional force between 12 outer ring surface of hose and 2 inner ring surface of casing and socket part increases, so that hose and core
The compactness connected between pipe 1 increases.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model by Patent Law.
