Description
Technical field
The utility model relates to rail traffic vehicles field more particularly to a kind of rubber hose crimping structures.
Background technique
In the systems such as locomotive, the fuel oil of vehicle, lubricating oil system, braking, for the ease of installation, hose and hard is mostly used greatly
The connected structure type of pipe.The hose coupling of the prior art is crimped using hose clamp card either pressing sleeve substantially with rubber tube cooperation
Mode, but in practice, the common failure phenomenon of the crimping mode of the prior art has sebific duct pull-off or hose assembly button
It is leaked at pressure, producing cause is other than the quality problems of sebific duct and connector for joint, predominantly withholding of technology.By to existing skill
The decomposition of art product finds that joint core is generally more thick and heavy, withholds rear joint core and does not deform, but leaves on sebific duct
Deep pressing sleeve impression, will affect the service life of rubber hose in this way.The pressing sleeve of the prior art is designed to interior pawl structure, connects
Head core is designed to outer pawl structure, can damage rubber hose, and the inner glue layer of rubber hose, which is scraped off, will lead to medium and constantly penetrate into；
The outer glue-line of rubber hose is scraped off, and using easily causing outer glue to peel off under long-term pressure, these defects all will seriously affect track
Hand over the service life and reliability of general service hose.
Summary of the invention
The purpose of this utility model is to provide a kind of rubber hose crimping structures, withhold connection rear joint core and pressing sleeve
It can be fitted close with rubber hose, and not damage the inner glue layer and outer glue-line of rubber hose, substantially increased rail traffic and use rubber
The life and reliability of glue hose.
The utility model is realized in this way:
A kind of rubber hose crimping structure, including pressing sleeve, joint core and rubber hose；The end surface of joint core is wave
Shape wave curved-surface structure, rubber hose are socketed on the waveform curved surface of joint core；Joint core is equipped with and withholds slot, is located at waveform
The rear side of curved surface, the rear end adaptation of pressing sleeve, which is embedded in, withholds in slot, and rubber hose is made to be wrapped in the wave of joint core by pressing sleeve
On shape curved surface.
The inner wall of the pressing sleeve is smooth surface and is fitted in rubber hose, if the outer wall of pressing sleeve is equipped with arterial highway boss.
When the pressing sleeve is pressed in rubber hose, the linkage section of pressing sleeve and rubber hose and joint core is deformed into and wave
The compatible curved-surface structure of shape wave curved surface.
The utility model compared with prior art, has the following beneficial effects:
1, the utility model is avoided using waveform curved-surface structure and smooth surface structure instead of the pawl structure of the prior art
The interior outer glue-line for damaging rubber hose prevents from leaking situations such as peeling off with outer glue, and breakage rate is reduced from the 40% of the prior art
To 0%, the service life of product is extended.
2, the utility model can be bonded well using waveform curved-surface structure guarantee rubber hose and is pressed in joint core,
The leakproofness for guaranteeing product, improves the use reliability of product.
The utility model can be fitted close withholding connection rear joint core and pressing sleeve with rubber hose, and it is soft not damage rubber
The inner glue layer and outer glue-line of pipe, substantially increase the life and reliability of rail traffic rubber hose.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model rubber hose crimping structure withheld before connection；
Fig. 2 is the schematic diagram of the utility model rubber hose crimping structure withheld after connection.
In figure, 1 pressing sleeve, 11 boss, 2 joint cores, 21 withhold slot, 3 rubber hose.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Refer to attached drawing 1 and attached drawing 2, a kind of rubber hose crimping structure, including pressing sleeve 1, joint core 2 and rubber hose
3；The end surface of joint core 2 is waveform curved-surface structure, and rubber hose 3 is socketed on the waveform curved surface of joint core 2；Connector
Core 2 is equipped with and withholds slot 21, and positioned at the rear side of waveform curved surface, the rear end adaptation of pressing sleeve 1, which is embedded in, is withheld in slot 21, makes rubber
Hose 3 is wrapped on the waveform curved surface of joint core 2 by pressing sleeve 1.
The inner wall of the pressing sleeve 1 is smooth surface and is fitted in rubber hose 3, if the outer wall of pressing sleeve 1 is convex equipped with arterial highway
Platform 11, it is preferred that can on the outer wall of pressing sleeve 1 turning twice radial direction boss 11, for withholding stress.
When the pressing sleeve 1 is pressed in rubber hose 3, the linkage section deformation of pressing sleeve 1 and rubber hose 3 and joint core 2
At curved-surface structure compatible with waveform curved surface, it is ensured that pressing sleeve 1, joint core 2 and rubber hose 3 are seamless applying, improve close
Envelope property and reliability.Preferably, 20 carbon constructional quality steels can be used in pressing sleeve 1, can be under the requirement for meeting bonding strength
Waviness curved-surface structure can be deformed.
In use, pressing sleeve 1 is detained by rubber hose 3 and pressing sleeve 1 by being socketed on the waveform curved surface of joint core 2 except interior
It is tightly withholding in slot 21, rubber hose 3 is made to seal the surface for being pressed on joint core 2, completion rubber hose 3 can with joint core 2
By connection.
Waviness curved-surface structure is designed in one end of joint core 2, different from the outer pawl structure of the prior art, pressing sleeve 1
Inner wall is designed to smooth surface structure, different from the interior pawl structure of the prior art, effectively prevents the glue-line damage of rubber hose 3；
The size of the waveform curved surface of the outer diameter of pressing sleeve 1, internal diameter and joint core 2 is by calculating and verification experimental verification, it is preferred that waveform
The radius of curved surface is 50mm, it is ensured that after withholding, pressing sleeve 1, rubber hose 3 and joint core 2 can be bonded compression well, not damage
Rubber hose 3 and the leakproofness that can guarantee product, prolong the service life, and improve the reliability of product.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the protection scope of the utility model,
Therefore, any modification, equivalent substitution, improvement and etc. made within the spirit and principle of the present invention, should be included in
Within the protection scope of the utility model.
