Abstract
The utility model discloses a kind of rubber hose coupling assembly, it includes sleeve pipe and core bar, and the sebific duct in the middle of sleeve pipe and core bar, it is characterised in that：The position that described sleeve pipe inner surface setting has correspondence sleeve pipe stepped tooth on stepped tooth, the core bar outer surface is provided with trapezoidal groove, correspondence sleeve pipe stepped tooth interstitial site is provided with stepped tooth, the utility model is widely used in hydraulic system.
Description
Technical field：
The utility model is related to a kind of sebific duct connector, more specifically to a kind of rubber hose coupling assembly.
Background technology：
Rubber hose coupling assembly species has much in the prior art, generally by the way of salient point or saw type tooth are set in sleeve pipe
To prevent sebific duct pull-off from hose assembly, as hydraulic system is to the development in high-pressure high-flow direction, to the sebific duct in system
The requirement of assembly it is also proposed the requirement of anti-high pressure, and hose assembly of the prior art in hyperpressure due in sleeve pipe
Salient point or the step depth of saw type tooth formation are shallower, and the steel wire bending amplitude withheld in rear sebific duct is smaller, therefore stress is less,
Separate easily sleeve pipe and core bar when being used in ultra-high voltage environment and gap occur, so that the problems such as producing oil leak.
Utility model content：
Technical problem to be solved in the utility model is to provide a kind of new rubber hose coupling assembly, so as to solve height
Leakage under pressure ring border, the technical scheme that it is used is：A kind of rubber hose coupling assembly, it includes sleeve pipe and core bar, with
And the sebific duct in the middle of sleeve pipe and core bar, wherein described sleeve pipe inner surface setting has right on stepped tooth, the core bar outer surface
Answer the position of sleeve pipe stepped tooth to be provided with trapezoidal groove, correspondence sleeve pipe stepped tooth interstitial site is provided with stepped tooth.
The utility model further technical characteristic is：
Stepped tooth on described sleeve pipe inner surface is isosceles trapezoid tooth.
The core bar outer surface is provided with least two stepped tooths in each interstitial site of correspondence sleeve pipe stepped tooth.
The position of the position of two stepped tooths at correspondence sleeve pipe two ends is not provided with trapezoidal groove on the core bar outer surface.
The beneficial effects of the utility model are：Because the utility model in described sleeve pipe inner surface setting has stepped tooth, institute
The position for stating correspondence sleeve pipe stepped tooth on core bar outer surface is provided with trapezoidal groove, is set in correspondence sleeve pipe stepped tooth interstitial site
There is stepped tooth, therefore the steel wire bending amplitude that hose assembly is withheld in rear sebific duct is increased considerably, such hyperbaric environment middle sleeve
Just it is not easily separate with tube core, so that the problem of solving oil leak in hyperbaric environment, also ensure that the quality of rubber hose coupling assembly.
Brief description of the drawings：
Fig. 1 is the structure sectional view of the embodiment of the utility model one；
Fig. 2 is the structure sectional view of Fig. 1 middle sleeves；
Fig. 3 is the structure sectional view of core bar in Fig. 1.
Embodiment：
1, accompanying drawing 2 and accompanying drawing 3 do more detailed description to the utility model below in conjunction with the accompanying drawings.
In the embodiment shown in fig. 1, a kind of rubber hose coupling assembly, it includes sleeve pipe 1 and core bar 2, and positioned at sleeve pipe 1
With the sebific duct 3 in the middle of core bar 2, the wherein inner surface setting of described sleeve pipe 1 has correspondence set on stepped tooth 101, the outer surface of core bar 2
The position of pipe stepped tooth 101 is provided with trapezoidal groove 201, and the correspondence interstitial site of sleeve pipe stepped tooth 101 is provided with stepped tooth
202.In the present embodiment, as shown in Figures 2 and 3, the stepped tooth on the inner surface of described sleeve pipe 1 is isosceles trapezoid tooth.The core
The outer surface of bar 2 is provided with a stepped tooth 202 in each interstitial site of correspondence sleeve pipe stepped tooth 101, in the present embodiment, is
Make the steel wire stress change curve in sebific duct more smooth, two of correspondence sleeve pipe 1 inner surface two ends on the outer surface of core bar 2
The position of stepped tooth is not provided with trapezoidal groove, the distribution of force more science of such sebific duct 3, so as to extend whole rubber hose coupling
The service life of assembly.
In actual applications, what can be set the stepped tooth on the inner surface of sleeve pipe 1 is more sparse, and the outer surface of core bar 2 is right
Answering each interstitial site of sleeve pipe stepped tooth 101, to be provided with two or three stepped tooths even more more.
Corresponded on stepped tooth 101, the outer surface of core bar 2 because the utility model has in the inner surface setting of described sleeve pipe 1
The position of sleeve pipe stepped tooth 101 is provided with trapezoidal groove 201, and correspondence sleeve pipe stepped tooth interstitial site is provided with stepped tooth 202,
Therefore the steel wire bending amplitude that hose assembly is withheld in rear sebific duct is increased considerably, particularly the outer surface of core bar 2 correspondence sleeve pipe ladder
The position of shape tooth 101 is bigger due to the steel wire bending amplitude being provided with trapezoidal groove 201, sebific duct, is covered in such hyperbaric environment
Pipe 1 and tube core 2 are just not easily separate, so that the problem of solving oil leak in hyperbaric environment, also ensure that rubber hose coupling assembly
Quality.
Technology contents and technical characterstic of the present utility model have revealed that as above, it being understood, however, that of the present utility model
Under creative ideas, those skilled in the art can make various changes and improve to said structure, including individually disclose here
Or the combination of claimed technical characteristic, and significantly include other combinations of these features, these deformations and/or combination
Each fall within the technical field involved by the utility model, and fall into the utility model scope of the claims, this practicality
New protection domain is defined by claims.
