Description
Technical field
The relevant a kind of shrink-fit structure of the present invention refers to the shrink-fit structure of the hand-held tool element of the good and long service life of a kind of bond strength especially.
Background technology
Hand-held tool elements such as sleeve are a kind of aid that often is used to screw or unscrew bolt in general traditional mechanical industry, because the size dimension of bolt is diversified in specifications, therefore need to prepare the ferrule element of the various different sizes needs on could adaptation work.And the general sleeve moulding of finding at present mostly is cylindrical, therefore it rolls easily and causes collection to be difficult for, when the collection sleeve, must just make things convenient for the user to deposit ferrule element by the auxiliary of box or pylon, because existing sleeve box does not relate to technical field of the present invention, so will not give unnecessary details.
And, the sleeve combination of existing sleeve rack all be utilize its with sleeve between frictional force or the plastic deformation of material itself reach the effect that combines ferrule element, therefore, when the sleeve combination produces the situation of abrasion, bond strength between itself and sleeve can be greatly affected, even the situation that causes sleeve to come off, improved necessity is in addition arranged really.
Summary of the invention
Main purpose of the present invention is to be disappearance that solves above-mentioned existing sleeve rack shrink-fit structure and the problem that use to go up inconvenience, and the fit body construction of the good and long service life of a kind of bond strength is provided.
Based on above-mentioned purpose, the invention provides a kind of shrink-fit structure, it belongs to a kind of can assemble the fit body construction that connects the hand-held tool element, wherein, this fit body has at least one can be for the column in conjunction with sleeve, and this column has a suitable length, and be provided with at least one top body of pulling in the outer peripheral edges of this column, relatively, in addition on the inner peripheral wall of this column at least correspondence be provided with one and press body, and this presses body and is connected with on the inner peripheral wall of this column, and this presses the usefulness that body has the elastic reset energy storage, makes this press the back side of body of pulling in this top of pulling, the corresponding top of body.
The present invention also provides another kind of shrink-fit structure, it belongs to a kind of fit body construction that connects the hand-held tool element, wherein: this body has at least one can be for the column in conjunction with sleeve, this column has a suitable length, then set firmly in a side of this column and to be assembled with a shell fragment, and the top contact end at this shell fragment top can be pulled in the combined hole internal face of this sleeve on corresponding top, provides this column in the bond strength in conjunction with sleeve with the elastic energy accumulation by this shell fragment.
According to such scheme, the present invention presses body to provide support this top bond strength of body in conjunction with sleeve time of pulling by this, perhaps the elastic energy accumulation by shell fragment is to provide this column in the bond strength in conjunction with sleeve, thereby, make the present invention can reach the effect in conjunction with the location of assembling sleeve and beneficial effect with the good and long service life of bond strength.

The specific embodiment
As for above-mentioned purpose of the present invention and advantage, be not difficult from the detailed description and accompanying drawing of following selected embodiment, to obtain to understand in depth.Certainly, the present invention is on some part or allow differently in the arrangement of part, but selected embodiment then described in detail in this specification, and shows its structure in accompanying drawing.
The present invention is relevant for a kind of fit body construction, at first see also shown in first embodiment of Fig. 1 to Fig. 4, its fit body construction mainly comprises a body 20, wherein 20 of this bodies are sheathed on joint portion 21 on the body of rod 10 and at least one for being formed in conjunction with the column 22 of sleeve 30 by one, and this column 22 that is hollow form has a suitable length, and its outward radial extends the tip position from this joint portion 21.
This column 22 is a hollow cylinder, the body 221 of pulling in the top that the arbitrary face of its periphery is formed with an at least one side hollow out, the free end that body 221 differs from this joint portion 21 and pull in this top has outwards extended a protuberance 222, these column 22 inner peripheral accommodation space walls are provided with one and press body 223 with respect to the pull one side of body 221 of this top, promptly this end that presses body 223 is connected in the internal face of this column 22, and this in addition end that presses body 223 then contacts the back side of the body 221 of pulling in this top, thereby, can press body 223 by this and pull body 221 in bond strength in conjunction with sleeve 30 to provide support this top, and this presses the usefulness that body 223 has elastic energy accumulation, in pulling the one side at least of two sides of body 221 adjacent to this top on, this column 22 is formed with in addition the broached-tooth design 224 of indentation, and then can improve the frictional force and the bond strength of 30 in this column 22 and sleeve, as shown in Figure 4.
Please cooperate again and consult Fig. 3 and shown in Figure 4, as the present invention during in conjunction with sleeve, wherein combined hole 31 internal faces of this sleeve 30 then can lateral sliding be oppressed the pull protuberance 222 of body 221 of this top, and this top body 221 of pulling is inwardly pushed and oppressed this and presses and contract in the body 223 to produce the top elastic force of pulling.Then continue to press to when location when this sleeve 30, the pull protuberance 222 of body 221 of this top then can be embedded in shrinkage pool 32 on sleeve combined hole 31 internal faces, to reach the purpose in conjunction with the sleeve location.Then, the elastic force effect owing to pull in this top that presses body 223, even using after a period of time, though and the pull protuberance 222 of body 221 of this top have the phenomenon of abrasion to produce, then this top body 221 of pulling still can be pulled elastic force with sleeve the is provided suitable top bond strength of pulling by this top that presses body 223.
The second embodiment of the present invention then as shown in Figure 5, wherein this body 20 is hung board 25 and at least one for being formed in conjunction with the column 22 of sleeve 30 by one, and this column 22 extends hangs the bottom position of board 25 from this, and this is hung board 25 and then can hang and be embedded the ferrule element that is assembled on this column 22.
The relevant third embodiment of the present invention then as shown in Figure 6, its side that is shown in the hollow form column 22 of this body 20 then sets firmly and is assembled with a shell fragment 28, and the curved arc shape top contact end at these shell fragment 28 tops can corresponding contact combined hole 31 internal faces in this sleeve 30, provides this column 22 in the bond strength in conjunction with sleeve 30 with the elastic energy accumulation by this shell fragment 28.
The announcement of the above embodiment is not in order to restriction the present invention only in order to explanation the present invention, and all displacements according to numerical value change of the present invention or equivalence element still belong to category of the present invention.
