Described anti-core bar slewing gear and described core bar are withheld between district and are provided with buffer groove.
The inner hole wall that district withheld by described core bar has multiple tracks groove, correspondingly with the double wedge of the corresponding position of described core bar to withhold with described core bar be connected to realize described outer sleeve body.
The inwall in described hose buckling district has annular tooth, and described annular tooth withholds the corresponding setting of double wedge and coordinate to be lived by the hose buckling inserted with corresponding on described core bar.
The outer edge surface of described anti-core bar slewing gear is polygon-shaped.
The outer edge surface of described anti-core bar slewing gear is hexagon shape.
The purpose of this utility model is also to provide a kind of buckle press joint, comprises core bar and overcoat, and described overcoat adopts described buckle press joint overcoat.
The utility model is connected with the anti-core bar slewing gear rotated for preventing core bar from rotating with attaching nut by the outside integral type of withholding district at the core bar of outer sleeve body, the inside of described anti-core bar slewing gear has core bar passing hole, outside has the polygon facet being convenient to Wrench clamping, attaching nut is screwed again after blocking this anti-core bar slewing gear by Wrench, thus prevent core bar and hose assembly from rotating along with the rotation of attaching nut, efficiently solve core bar and hose assembly and rotate cause hose assembly to produce technical problem that distortion affects the working life of hose assembly.
Accompanying drawing explanation

Figure 2 shows that the schematic diagram of the buckle press joint overcoat that the utility model embodiment provides;
Figure 3 shows that the schematic side view of buckle press joint overcoat from anti-core bar slewing gear side that the utility model embodiment provides;
Figure 4 shows that the schematic diagram of the buckle press joint that the utility model embodiment provides.
Embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Refer to shown in Fig. 2 ~ 4, a kind of buckle press joint overcoat, comprise outer sleeve body 1, described outer sleeve body comprises core bar and withholds district 11 and hose buckling district 13, described core bar is withheld district 11 and is connected by transition zone 12 with hose buckling district 13, the outside integral type that district 11 withheld by described core bar is connected with for preventing core bar 5 to rotate with attaching nut 4 and the anti-core bar slewing gear 2 that rotates, and the inside of described anti-core bar slewing gear has core bar passing hole, and outside has the polygon facet being convenient to Wrench clamping.
Because anti-core bar slewing gear is direct and outer sleeve body is combined in one, thus, when tightening attaching nut, available spanner blocks this anti-core bar slewing gear, prevent described core bar 5 in the problem that core bar 5 transfer occurs when the frictional force of end face 51 is less than the frictional force of other end 52 (end face 52 contacts with the infolding card edge of attaching nut 4), prevent core bar and hose assembly from rotating along with attaching nut, thus effectively prevent core bar and hose assembly rotates along with the rotation of attaching nut, efficiently solve core bar and hose assembly and rotate the technical problem causing hose assembly to produce distortion.
As another embodiment, further, described anti-core bar slewing gear 2 and described core bar are withheld between district 11 and are provided with buffer groove 3, this buffer groove 3 is located on described anti-core bar slewing gear and district withheld by described core bar, the flute profile (sectional shape) of described buffer groove can be rectangle, also can trapezoidal or concave arc shape, concrete shape is not limit.
As another embodiment, the inner hole wall that district 11 withheld by described core bar has multiple tracks groove 15, corresponding with the double wedge 53 of the corresponding position of described core bar 5, to withhold with described core bar 5 be connected to realize described outer sleeve body 1, can realize being interlocked by the double wedge of the corresponding position of this multiple tracks groove and described core bar, realize described outer sleeve body and be fixedly connected with described core bar.
As another embodiment, the inwall in described hose buckling district 13 has annular tooth 14, and described annular tooth withholds the corresponding setting of double wedge 54 and coordinate to be lived by the hose buckling inserted with corresponding on described core bar 5.
In specific implementation, the two bottom sides of described annular tooth is cone structure, the interval between each annular tooth, and namely bottom interval distance can be identical, also can be different, and the top outer edge surface of described annular tooth can be convex face, also can be plane structure.
As another embodiment, the outer edge surface of described anti-core bar slewing gear 2 is polygon-shaped, by the polygon facet that this is polygon-shaped, this anti-core bar slewing gear clamping can be prevented from rotating convenient wrench instrument, thus effectively prevent from rotating with the outer sleeve body of described anti-core bar slewing gear one, thus prevent core bar and hose assembly from rotating, prevent hose assembly from producing torsional deformation when tightening attaching nut.
Preferably, the polygon facet of described anti-core bar slewing gear 2 is hexagon shape, hexagonally meets NBS limit molded dimension, and convenient wrench tool holder operates, and of coursing, also can be that other is polygon-shaped, as both sides shape, quadrilateral etc.
Shown in Figure 4, the purpose of this utility model also provides a kind of buckle press joint, and this buckle press joint comprises core bar 5, attaching nut 4 and overcoat, and described overcoat adopts above-mentioned buckle press joint overcoat.Overcoat due to this buckle press joint adopts above-mentioned overcoat, thus, can prevent core bar and hose assembly from rotating along with the rotation of attaching nut with imitating, efficiently solve core bar and hose assembly and rotate cause hose assembly to produce technical problem that distortion affects the working life of hose assembly.
More than by analyzing, can find out, the utility model is connected with the anti-core bar slewing gear rotated for preventing core bar from rotating with attaching nut by the outside integral type of withholding district at the core bar of outer sleeve body, the inside of described anti-core bar slewing gear has core bar passing hole, outside has the polygon facet being convenient to Wrench clamping, attaching nut is screwed again after blocking this anti-core bar slewing gear by Wrench, thus prevent core bar and hose assembly from rotating along with the rotation of attaching nut, efficiently solve core bar and hose assembly and rotate cause hose assembly to produce technical problem that distortion affects the working life of hose assembly.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
