Description
Technical field
The utility model relates to gas expansion shaft, refers to a kind of most curved tabs that are provided with on an axostylus axostyle surface especially, and should form the discontinuous gap of interruption.
Background technology
Traditional gas expansion shaft (air shaft) is to be arranged on the taking-up equipment with being rotated, and can this gas expansion shaft be expanded by pressurized air to be resisted against a body 16 (as: paper tube or the plastic pipe) inner tubal wall that is set on this gas expansion shaft, this taking-up equipment is wound on a material (as: paper wood, rubber material, metal material, cloth material or wire rod) on this body 16 again and makes a coiling finished product.
Again, traditional gas expansion shaft is to comprise following several pattern according to its external form, as: button type (buttonmodel), key tooth-like (serrated key model), key-strip type (1ug/stripe) and plate-sheet-type etc., and the suitable respectively different material that is wound on of the gas expansion shaft of aforementioned various types, or because there is inborn shortcoming in the gas expansion shaft of a certain pattern, and the maker of gas expansion shaft improves according to this shortcoming and produced, for example: No. the 475593rd, the novel patent announcement of China " plate-sheet-type gas rise winding off spindle " (to call the patent case in the following text), promptly belong to the latter, this patent case is because the set jacking block of button type gas expansion shaft, only can lean on the position of these body 16 parts, make that this body 16 is different because of the application force that bears by position that leans and the position that is not leaned, cause the phenomenon of these body 16 distortion even distortion.
Therefore, this patent case is modified to the plate-sheet-type gas winding off spindle that rises at the structure of this button type gas expansion shaft, see also Figure 1 and Figure 2, and this plate-sheet-type gas expansion shaft includes an axle center main body 11, the plural groups correspondence is periphery in the clip plate 12 and outer plate 13 of axle center main body 11 inside and outside both sides, be located at the air bag 14 in the position that this clip plate 12 centered on, most radially wore this axle center main body 11 and in order to link should in, outer plate 1312,13 attaching parts 15, and be arranged at this clip plate 12 and this axle center main body 11 between an elastic component (not shown), when this air bag 14 is the inflation state and forces this clip plate 12 to affect this outer plate 13 towards outside displacement, this outer plate 13 can be affected and be pushed against in the inner tubal wall that is set on the body 16 on these outer plate 13 formed peripheries, allow this body 16 and this plate-sheet-type gas winding off spindle that rises rotate synchronously, to batch or to send material, because this outer plate 13 is to be the arc elastic board chip, this outer plate 13 can be subjected to urging of this body 16 and produce elastic deformation, make on its inner tubal wall that is resisted against this body 16 fully, make this body 16 obtain to support uniformly, guarantee its out of roundness.
But, no matter be which kind of gas expansion shaft as previously mentioned, all be that material is batched on this body 16, after the material of this coiling finished product used, this body 16 was lost with regard to having become waste, it seems it is quite waste with regard to the viewpoint of environmental protection, and reclaim this body 16 if will peddle the manufacturer of this coiling finished product, then can cause this manufacturer's cost burden, and this plate-sheet-type gas winding off spindle that rises is because of following reason, and material directly can't be wound on the surface of this gas expansion shaft:
Though 1, this plate-sheet-type gas winding off spindle that rises has goodish out of roundness, 13 of the outer plates that winding off spindle in office two is adjacent but this plate-sheet-type gas rises, still there is a little gap s, if directly material is wound on the surface of this outer plate 13, may make material in the process of batching, can be absorbed in the s of gap.
2, after the pressurized air in this air bag 14 discharged, it is littler that the gap s that this adjacent outer plate is 13 can become, and will clip to the material that is trapped in the s of this gap, makes material to take off from this plate-sheet-type gas winding off spindle that rises.
So, if a kind of gas expansion shaft that need not put this body 16 can be arranged, can meet environmental protection requirement, needn't reclaim this body 16 by manufacturer again, believe will be popular find pleasure in see.
In view of this, for improving the shortcoming of prior art, the creator is through the permanent research and experiment of making great efforts, and development and Design goes out a kind of gas expansion shaft of the present utility model finally.
