Description
Technical field：
The present invention relates to a kind of connector, more specifically to a kind of rubber hose coupling.
Background technology：
At present rubber hose coupling on the market as shown in figure 1, including：It is provided with the joint core bar 1 that tube core withholds groove 3；It is provided with outer
Cover the overcoat 2 of attaching part 4；In practical application during connection rubber tube, sebific duct stripping mucilage binding is first entered into overcoat 2, then plugged in joint core bar 1
In entering glue pipe, then it is buckled in by withholding overcoat attaching part 4 by overcoat 2 tube core of joint core bar 1 and withholds in groove 3, forms connection
Structure；Due to the presence of allowance for finish, withhold rear result and following several situations occur：The first is that tube core withholds groove 3
Respectively upper, middle and lower tolerance when, match somebody with somebody apply mechanically the bottom thickness of overcoat attaching part 4 simultaneously correspondence be also upper, middle and lower tolerance when, detain
Tube core withholds the bottom gapless of groove 3 after pressure, and effect is relatively good；Second, due to produce it is supporting when, will not each of go first one by one
It is supporting, therefore just occur that what tube core withheld tolerance on groove 3 matches somebody with somebody tolerance under the bottom thickness of overcoat attaching part 4, after at this moment withholding
Therebetween occur the phenomenon in removable gap 5, later stage joint for a long time in use, the place of withholding loosening may be caused, from
And influence sealing effectiveness and oil leakage phenomenon occur；The third, is exactly that tube core withholds the thick with the bottom of overcoat attaching part 4 of 3 times tolerances of groove
Tolerance on degree, such bottom of overcoat attaching part 4 is too thick, and to withhold the groove width of groove 3 narrow for tube core, withholds rear tension, after withholding just
Tube core can be made to withhold the overstress of groove 3, be directed at the later stage using when there is tube core phenomenon of rupture, potential safety hazard be present.
The content of the invention：
The technical problems to be solved by the invention are to provide a kind of novel rubber hose connecter, and technical scheme is used by it：It is a kind of
Rubber hose coupling, it includes：The joint core bar that tube core withholds groove is provided with, is provided with the overcoat of overcoat attaching part；Wherein described pipe
Core withholds the groove left side and is designed with 10 ° ~ 20 ° tapers, and the right is designed with 5 ° ~ 10 ° tapers, and the tube core withholds groove bottom land both ends as circle
Arc R angles, R angular radius are 0.5mm ~ 1.5mm.
Technical characteristic of the invention further is：
The tube core withholds the groove left side and is designed with 15 ° of tapers, and the right is designed with 10 ° of tapers, and the tube core withholds groove bottom land both ends
For circular arc R angle, R angular radius are 0.5mm.
The tube core withholds the groove left side and is designed with 20 ° of tapers, and the right is designed with 8 ° of tapers, and the tube core withholds groove bottom land two
It is 1.0mm to hold as circular arc R angle, R angular radius.
The tube core withholds the groove left side and is designed with 10 ° of tapers, and the right is designed with 5 ° of tapers, and the tube core withholds groove bottom land two
It is 1.5mm to hold as circular arc R angle, R angular radius.
The overcoat attaching part bottom both ends are circular arc R angle, and R angular radius are 0.5mm.
The beneficial effects of the invention are as follows：
The groove left side is withheld due to tube core and is designed with 10 ° ~ 20 ° tapers, the right is designed with 5 ° ~ 10 ° tapers, and the tube core withholds groove groove
Bottom both ends are circular arc R angle, and R angular radius are 0.5mm ~ 1.5mm, and the joint core bar is withheld with overcoat when being connected, and the overcoat is withheld
The bottom in portion is connected to tube core and withheld on groove bottom land R angles, therefore the tube core of joint core bar withholds groove groove width and overcoat attaching part bottom
When limit tolerance occurs in portion's thickness, it can adjust and withhold position, the overcoat attaching part after withholding withholds groove bottom land in tube core will not
There is removable gap, will not be loosened using during stress.And it is thicker to cover attaching part bottom outside, joint core bar withhold groove bottom land compared with
When narrow, overcoat attaching part can be withheld to be withheld on the R angles of groove bottom land both ends or tube core is withheld on the conical surface of groove the right and left in tube core, cone
There are enough bit spaces that allows on face, do not have tension phenomenon after withholding, therefore solve the problems, such as that core bar is broken when in use, arrange
Except hidden danger, the service life of joint is extended.
Brief description of the drawings：
Fig. 1 is prior art construction sectional view,；
Fig. 2 is the structure sectional view of one embodiment of the invention；
Fig. 3 is that position partial enlarged drawing is withheld in Fig. 2.
Embodiment：
Below in conjunction with the accompanying drawings 2 and accompanying drawing 3 more detailed description is done to the present invention.
Fig. 2 is the structure sectional view of one embodiment of the invention, and in the present embodiment, a kind of rubber hose coupling, it includes：Set
The joint core bar 1 for having tube core to withhold groove 3, it is provided with the overcoat 2 of overcoat attaching part 4；It is as shown in Figure 3 that wherein described tube core withholds groove
The left side is designed with 15 ° of tapers 6, and the right is designed with 10 ° of tapers 7, and it is circular arc R angle 8 that the tube core, which withholds groove bottom land both ends, and R angles are partly
Footpath is 0.5mm.In the present embodiment, the overcoat attaching part bottom both ends are similarly circular arc R angle, and R angular radius are 0.5mm.
In actual applications, the tube core withholds groove left side taper 6 and is also designed to 20 ° or 10 °, and the right taper 7 is also
5 ° or 8 ° are can be designed as, the R angular radius that the tube core withholds groove bottom land both ends circular arc R angle 8 can also be 1.0mm or 1.5mm.
Because tube core withholds the right and left of groove 3 design tapered 6,7, it is circular arc R that the tube core, which withholds the bottom land both ends of groove 3,
Angle, therefore when the joint core bar 1 is withheld with overcoat 2 and is connected, the bottom of the overcoat attaching part 4 is connected to tube core and withholds groove groove
, can on the R angles of bottom, therefore when the tube core of joint core bar 1 withholds the groove width of groove 3 and the bottom thickness of overcoat attaching part 4 and limit tolerance occurs
With regulation withhold position, it is not in removable gap 5 that the overcoat attaching part 4 after withholding withholds the bottom land of groove 3 in tube core, using by
It will not be loosened during power.And it is thicker to cover the bottom of attaching part 4 outside, the tube core of joint core bar 1 withhold the bottom land of groove 3 it is narrower when, overcoat is withheld
Portion 4 can be withheld withholds on the bottom land both ends R angles of groove 3 or tube core is withheld on the conical surface of the right and left of groove 3 in tube core, has on the conical surface enough
Allow bit space, tension phenomenon is not had after withholding, therefore solve the problems, such as that core bar is broken when in use, eliminates hidden danger,
Extend the service life of joint.
The technology contents and technical characterstic of the present invention have revealed that as above, it being understood, however, that in the creative ideas of the present invention
Under, those skilled in the art can make various changes and improve to said structure, including individually disclose here or require protect
The combination of the technical characteristic of shield, and significantly include other combinations of these features, these deformations and/or combination each fall within this
In the involved technical field of invention, and the protection domain of the claims in the present invention is fallen into, protection scope of the present invention is with right
Claim is defined.
