Abstract
The present invention relates to a handle structure of hand tool, in particular, it relates to a composite layer screw driver handle and its manufacturing method. Said hadle structure characterized by its material is composed of internal core and external layer. Said internal core is a hard material including first elastic body, and the external layer is a soft material including second elastic body, and both the elastic bodies can be merged together. The interface between the internal core and external layer contains a clinkery layer, and said clinkery layer material at least is formed from first elastic body and second elastic body. Besides, it also provides a method for producing the above-mentioned product.
Description
The present invention relates to a kind of is the handle arrangement of the hand-operated tools of characteristics with the material, particularly a kind of composite layer screw driver handle and manufacture method thereof.
Composite layer screw driver handle of the prior art, between its inner core and the skin or adopt bonding or adopt and inlay with compound affixed, this compound affixed mode can't allow inner core and skin form an organic whole, so damage phenomenons such as use often come off, directly influence screwdriver service life.
The objective of the invention is to overcome weak point of the prior art, and provide a kind of use inner core to separate with outer difficult drop-off, grow and better simply composite layer screw driver handle of manufacture method and manufacture method thereof service life.
The objective of the invention is to realize by following approach.
Composite layer screw driver handle, it comprises, inner core, comprise a kind of solid-state but can soften, the normal temperature state is the material of hard down, this material comprises a kind of first elastomer, outer, comprise a kind of solid-stately but can soften, the normal temperature state is soft material down, this material comprise a kind of can with second elastomer of first elastomer fusion, the outer surface of its ectomesoderm distribution and the inner core of combining closely, interface between inner core and skin comprises the clinkering layer, this clinkering layer material be from inner core in abutting connection with interface superficial layer and outer in abutting connection with interface superficial layer the two, it is made up of first elastomer and second elastomer at least.
The composite layer screw driver handle manufacture method, it may further comprise the steps, inner core under a kind of molten condition of extruding continuously from extruder is provided, this inner core comprises and is the material of hard under a kind of normal temperature state, this material comprises first elastomer, skin under the molten condition that will extrude continuously from another mould distributes along the inner core outer ring, it is soft material that this skin comprises under a kind of normal temperature state, this material comprises a kind of second elastomer, through contacting of outer and inner core, make second elastomer and the organic fusion of first elastomer.
The firm material of extruding from the mould outlet end, at this moment also be in molten condition, utilize the state that promptly loses in this wink slightly, realize inner core and outer field organic fusion and be consolidated into one, guarantee so in use, inner core and outer being difficult to break away from, and prolonged service life greatly, and manufacture method is extremely simple again, in addition, the inner core of hard can be effective as the skeleton of screw driver handle, and opposite soft skin but can make comfortable feel, softness, and has anti-skidding, on-slip function.
Accompanying drawing 1 is the composite layer screw driver handle front view.
Accompanying drawing 2 is the A-A cutaway views among Fig. 1.
Below we further describe the present invention in conjunction with the accompanying drawings.Most preferred embodiment:
With reference to accompanying drawing 1 and accompanying drawing 2, composite layer screw driver handle, it is made up of inner core 1 and outer 2 etc., and wherein inner core 1 comprises a kind of solid-stately but can soften, and the normal temperature state is that the material of hard, this material comprise a kind of first elastomer down; Outer 2 comprise a kind of solid-stately but can soften, and the normal temperature state is soft material down, and this material comprises a kind of second elastomer, can fuse with first elastomer; Outer 2 by 6 band shape members along uniform the forming of inner core 1 outer surface, interface between inner core 1 and outer 2 comprises the clinkering layer, this clinkering layer material be from inner core 1 in abutting connection with interface superficial layer and outer 2 in abutting connection with the superficial layer of interface the two, it is made up of first elastomer and second elastomer, and first elastomer and second elastomer are rapid vinyl chloride.
The composite layer screw driver handle manufacture method, may further comprise the steps, inner core 1 under a kind of molten condition of extruding continuously from extruder is provided, this inner core 1 comprises under a kind of normal temperature state for solid-state, the material of hard, this material comprises first elastomer, the molten skin 2 that touches under the state that to from another mould, extrude continuously, distribute along inner core 1 outer ring, this skin 2 comprises under a kind of normal temperature state for solid-state, soft material, this material comprises second elastomer, through outer 2 with the contacting of inner core 1, make second elastomer and the organic fusion of first elastomer in abutting connection with interface layer.Outer 2 be by ring set the inner ring of the ring mould of inner core 1 mould outlet end radially the port of export be able to stream and overlay on inner core 1 surface.
It is same as the prior art that present embodiment is not stated part.
