Fig. 2 is the structural schematic diagram of casing 2 of the invention.
Fig. 3 is that inner tube 1 and casing 2 clamp the assembling schematic cross-sectional view before the withholding of hose 3.
Specific embodiment:
Specific embodiment of the invention is shown in detail in conjunction with attached drawing, it should be noted that embodiments of the present invention are
To be not construed as the limitation to claims of the invention convenient for the understanding to technical solution of the present invention.
Referring to Figure 1~Fig. 3, specific embodiments of the present invention are as follows: including hose 3, clamping the casing 2 of hose 3 and interior
Pipe 1, the inner wall of casing 2 have interior tooth button 4, and there is outer tooth button 5 in the outer surface of inner tube 1, and shown in Fig. 3 is the package assembly before not withholding
Signal, A shown in the drawings are the internal diameter of inner tube 1, and B is the outer diameter of inner tube 1, and C is the maximum outside diameter of the outer tooth button 5 of inner tube 1, D
For the spacing of the outer tooth button 5 of inner tube 1, E is the minimum diameter of the interior tooth button 4 of casing 2, and F is the internal diameter of casing 2, and G is casing 2
Outer diameter, H are the spacing of the interior tooth button 4 of casing 2, and X is the outer diameter of hose 3；It is above-mentioned to give buckleing for inner tube 1, casing 2 and hose 3
The mark of the English alphabet of package assembly and relevant significant points before pressure applies one to the external of casing 2 by buckle machine
A centripetal pressure, after casing 2 deforms after squeezing tube 3, casing 2, hose 3 and inner tube 1 form an overall structure, substantially
Two are formed due to the presence of interior tooth button 4 and outer tooth button 5, between the surfaces externally and internally and casing 2 and the surface of inner tube 1 of hose 3 to fit
Convex-concave surface assigned in interior tooth button 4 and outer tooth button 5, above-mentioned convex-concave surface are both the sealing surface and soft for preventing liquid from revealing
The frictional resistance face of the displacement of generation when 3 stress of pipe, therefore above-mentioned convex-concave surface is to the performance or/and quality of hose assembly
It is of great significance, while casing 2 is deformed under the action of buckle press, which also has important meaning to the quality of casing 2
Justice；5 pairs of formation convex-concave surfaces of interior tooth button 4 and outer tooth button have direct effect, therefore key of the invention is the quantity of outer tooth button 5
Greater than the quantity of interior tooth button 4, the minimum diameter of interior tooth button 4 and the outer diameter difference M of hose 3 are 1.6~3.0mm, due to outer 5 He of tooth button
That there are quantity is poor for interior tooth button 4, and the shape of convex-concave surface above-mentioned and the frictional force of two convex-concave surfaces has been varied or adjusted, had both mentioned
The high frictional force for preventing the performance of leak liquid from balancing two convex-concave surfaces again, improving prevents from falling off and compressive property；
On the one hand the restriction of the outer diameter difference M of the minimum diameter and hose 3 of above-mentioned interior tooth button 4, substantially defines the deformation of casing 2
Amount, on the other hand defines interior tooth button 4 to the amount of compression of the outer surface of hose 3, by largely testing and detecting, the mistake of M value
The big or too small performance to hose assembly has an impact, and if M value is excessive, then the deflection of casing 2 is excessive, will cause casing 2
There are a large amount of fine crack or damages in tube wall, lead to the resistance to compression of casing 2 or/and the reduction of anti-pressure ability, are especially having
During the liquid flowing of pressure, hose assembly often in vibrational state, above-mentioned fine crack can accelerate metal fatigue and
The service life for reducing hose assembly will appear joint breaking when serious and the accident that causes hose 3 to be hurted sb.'s feelings；If above-mentioned M
It is worth too small, it will cause assembling is difficult, and interior tooth button 4 may be made to 3 excess compression of hose, part is caused to the rubber of hose 3
The injury of shearing and tearing influences leakproofness and leads to the technical performance of hose assembly.
Hose assembly technical performance is influenced in addition to above-mentioned technical characteristic, the wall thickness of casing 2 is also an influence factor,
In one embodiment, the wall thickness of casing 2 is 1.5~3.5 times of the minimum diameter of interior tooth button 4 above-mentioned and the outer diameter difference M of hose 3；
The excessive one side needs of the wall thickness of casing 2 greatly withhold pressure, are deposited on the direction of wall thickness during withholding
It is unfavorable to the inside crystal phase structure of casing 2 in excessive barometric gradient, and the deformation of pars intramuralis is increasingly complex and make the equal of material
One property is bad, can also generate excessive internal stress and have an impact to intensity, therefore wall thickness is an important parameter selection, certainly
The too small then intensity of the wall thickness of casing 2 is inadequate, and shear-deformable rate when withholding is excessive, and 3 D deformation is insufficient；Above-mentioned set
The wall thickness of pipe 2 is preferably 1.8~2.5 times of the minimum diameter of interior tooth button 4 and the outer diameter difference M of hose 3 more preferably, both to have ensure that set
The intensity of pipe 2 it is contemplated that the wall body of casing 2 reasonable deformation rate, it is also contemplated that 3 D deformation situation inside wall body and interior
The factors such as stress, applicant has done a large amount of test and the dissection of casing 2 tests and analyzes, and obtains above-mentioned technical parameter.
The depth of the interior tooth button 4 of the casing 2 be 1.5~2.5mm, after casing 2 is withheld deformation, casing 2 it is interior
Tooth button 4 oppresses hose 3, forces 3 surface of hose to form the convex-concave surface for adapting to the shape that interior tooth buckles 4, when having external force or/and gravity
When acting on the drawing force constituted, interior tooth button 4 forms the resistance area and sealing surface of multiple bumps with hose 3, and the depth of interior tooth button 4 is not
It is preferably excessive or too small, although the depth of interior tooth button 4 is excessive can to increase above-mentioned concave-convex resistance area, meeting during withholding
Excessive shear action (perpendicular to wall surface) is generated to rubber surface, makes to generate in the rubber surface and certain depth of hose 3 big
The micro-crack of amount leads to the reduction of sealing performance and resistive drag force performance, in some instances it may even be possible to can force rubber layer inside hose 3 and/
Or wire enhancement layer generates excessive deformation and destroys the binding force between rubber layer and wire enhancement layer, influences hose 3
Self-strength and the frictional force between casing 2, if the depth of interior tooth button 4 is too small certainly, interior tooth button 4 and 3 surface of hose
Rubber deformation and/or the blocking surface that is formed of accumulation it is too small, then frictional force is too small, keep hose 3 easy to fall off, therefore select it is suitable
Interior tooth button 4 depth value to improve hose assembly performance it is extremely important, especially in conjunction with casing 2 above-mentioned wall thickness value and
M value, selecting the depth value of interior tooth button 4 is both a difficult job and a highly important technical indicator；In the present invention
In, the depth value of preferred casing 2 is 1.8~2.2mm, and the material capability certainly based on casing 2 and hose 3 can also be made small
Adjustment, similarly the depth of the outer tooth button 5 of inner tube 1 above-mentioned is 1.5~3.5mm, and the depth of preferred outer tooth button 5 is 1.8
~2.2mm；Since the internal diameter of the standby casing 2 of made of metal is much larger than the outer diameter of inner tube 1, the convex-concave surface of the surfaces externally and internally of hose 3
Area have quite poor away from therefore the frictional force of 3 surfaces externally and internally of hose is different, the usually outer surface of hose 3
Frictional force is greater than the frictional force of inner surface, this is unfavorable to the performance of hose assembly, therefore obtains the outer of inner tube 1 through a large number of experiments
The quantity that the quantity of tooth button 5 should be greater than the interior tooth button 4 of casing 2 is 1~2 tooth button, and the depth of outer tooth button 5 is greater than casing 2
Interior tooth button 4 0.1~0.3mm of depth, to increase the frictional force between hose 3 and inner tube 1, when hose 3 being made to be stretched power,
The frictional force of its surfaces externally and internally tends to balance as far as possible.
To further increase leakproofness and tensile resistance, the interior tooth button 4 of casing 2 is set with the outer tooth button 5 of inner tube 1 by parallel
The tooth button and spiral tooth button set are constituted, and above-mentioned tooth button disposed in parallel refers to that the circle section of adjacent tooth button is parallel surface
Again vertical with the circle center line connecting of tooth button, the interior tooth button 4 and outer tooth button 5 being arranged in this way have taken into account the tensile capacity of hose assembly and close
Envelope property appropriate balance；To be again the comprehensive performance for further increasing hose assembly, the interior tooth button 4 of casing 2 and the outer tooth button of inner tube 1
5 contraposition settings shift to install, and it is same that so-called contraposition setting refers to that interior tooth button 4 and outer tooth button 5 are located on the axis of hose assembly
One position or on the disc of axis same position, the surfaces externally and internally of such hose 3 by symmetrical extruding force, using pair
The frictional force of hose 3 make it is fairly accurate assessment and raising frictional force or interior tooth buckle 4 and outer tooth buckle 5 and shift to install (Fig. 3
It is shown), it can suitably increase the depth value of tooth button in this way, especially when the thickness of hose 3 itself is little, the tooth that shifts to install
Buckle structure can further improve leakproofness and guarantee tensile resistance.
Although the composition of hose assembly be not it is sufficiently complex, it is withheld the process being integrated by three components and is related to component
3 D deformation, therefore the deformation is extremely complex, and hose assembly is related to the stream of complicated pressure fluid in use state
Dynamic, stress condition is also extremely complex, therefore the influence factor of the performance of hose assembly is more, and the determination to parameters of operating part is exactly one
A the problem of can not can solve at present from the calculating of theoretical or model.Therefore, applicant comparative withhold, dissects pair by a large amount of
The work such as the analysis than, test parameters, achieve technical solution of the present invention, that is to say, that the technical scheme is that a large amount of
Test, theory analysis result and reflection, to improve and guarantee hose assembly comprehensive performance be it is vital, have weight
Want meaning.
