The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Shown in Fig. 1～3, of the present utility model in the cover bracing or strutting arrangement comprise that the columniform fixed cover 11 of a hollow, the sidewall of this fixed cover 11 are provided with two symmetrically can be along the jacking block 2 of the radial expansion of fixed cover 11.This jacking block 2 comprises that a protuberance 21 and that is positioned at these fixed cover 11 inside radially extends to ejection part 23 outside fixed cover 11 sidewalls from this protuberance 21 along fixed cover 11.
In the present embodiment, cover bracing or strutting arrangement is used for fixing the support member for the treatment of that has internal thread that need be arranged on product inside in this.Therefore, be provided with external screw thread on the surface of ejection part 23 with adaptive with this internal thread.
If the protuberance 21 that the cover bracing or strutting arrangement is used in of the present utility model acts on smooth inner surface, then ejection part 23 can be the plane, cambered surface, perhaps other and the adaptive shape of inner surface for the treatment of support component.
In addition, cover bracing or strutting arrangement also comprises one first swivelling cover 3 and one second swivelling cover 4 in this.
Be provided with first chute 31 corresponding respectively with the protuberance 21 of two jacking blocks 2 in the upper surface of first swivelling cover 3.Described first chute 31 is a circular arc, and the central angle of circular arc points to the center of circle.Every section circular arc includes an ejection part and the yielding portion near fixed cover 11 centers away from fixed cover 11 centers.
It is adaptive also to be provided with second chute 41, the second chutes 41 and first chute 31 identical with first chute, 31 structures on second swivelling cover 4.Under the acting in conjunction of this first chute 31 and second chute 41, make radially stable, flexible swimmingly that jacking block 2 can be at fixed cover 11.First swivelling cover 3 and second swivelling cover 4 are fixing by screw 7.
When first swivelling cover 3 and 11 rotations of second swivelling cover, 4 relative fixed cover, first chute 31 rotates relative to protuberance 21 with the second corresponding with it chute 41.As shown in Figure 4, when ejection part went to the dead astern of protuberance 21, jacking block 2 extended radially out along fixed cover 11, shored from the inside for the treatment of support member 6, made and treated that support member 6 closely contacts with product 5.When yielding portion went to the dead astern of protuberance 21, jacking block 2 with safety, withdrawed from the inside for the treatment of support member 6 along the radial contraction of fixed cover 11 swimmingly.
In addition, upper and lower two end faces at protuberance 21 also are equipped with a guide rod 22 that extends along the axis direction of fixed cover 11.Slide for guide rod 22 and on first chute 31, also be provided with an identical with it guiding groove 32 of bearing of trend.
And, also be provided with a locking mouth 33 adaptive, thereby avoid jacking block 2 under treating the reaction force of support member, to withdraw in the sidewall with this guide rod 22 at guiding groove 32 end corresponding with the ejection end of first chute 31.Same, on second chute 41, also be provided with a guiding groove 42 that bearing of trend is identical with it, at this guiding groove 42 end corresponding, also be provided with a locking mouth adaptive with this guide rod with the ejection end of second chute 41.The guiding groove 32 on guiding groove 42 on second swivelling cover 4 and locking mouth and first swivelling cover 3 and the effect of locking mouth 33 are identical, do not repeat them here.
In addition, end at fixed cover 11 also is provided with the sealed end 12 of a diameter greater than this fixed cover 11, an end that contacts with the end face for the treatment of support member or product at sealing end 12, and the lateral wall of fixed cover 11 is respectively equipped with draw-in groove 15 and 16 and is used to be provided with the sealing ring (not shown).
Though more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
