The specific embodiment
Hereby coordinate and graphic preferred embodiment of the present invention is described in detail as follows.
As shown in Fig. 2～Fig. 5, the open-end wrench of the present embodiment unloads a screw terminal s (as shown in Figure 5) in order to screw lock/spiral shell, and the structure of this open-end wrench comprises: a body 20 and a cover body 30.Body 20 have a head 21 and be connected with this head 21 one hold portion 22, head 21 also has a fork 211, these fork 211 inner side edges 2111 form similar U-shaped breach 212.One the 3rd plate body 33 that cover body 30 has one first plate body 31, second plate body 32 with respect to this first plate body 31 and connects this first plate body 31 and this second plate body 32, the surface curvature in the 3rd plate body 33 outsides and form one and pull mouthfuls 331, this is pulled mouth 331 and unloads a screw terminal s (as shown in Figure 5) in order to screw lock/spiral shell, and the outer margin contour of this first plate body 31, this second plate body 32 and the 3rd plate body 33 defines a cover mouth 34 (as shown in Figure 2, Figure 4 shows) jointly.Cover body 30 glues together engineering method with the joint applications of body 20, but with this engineering method, be not limited, this cover mouth 34 penetrates this fork 211 of this body 20 and makes the 3rd plate body 33 of this cover body 30 corresponding to the position of this breach 212, and coated this breach 212, and making this cover body 30 be embedded in head 21 gummed (as shown in Fig. 3, Fig. 5) of this body 20, this that makes to contact screw terminal s pulls mouthfuls 331 and connect that to pull mouthfuls 331 the first plate body 31, the second plate body 32 be same material, integrally formed making.
In an above-mentioned embodiment, the strength of materials of this cover body 30 and density are greater than the strength of materials of this body 20, required rigidity intensity while unloading screw terminal s to deal with screw lock/spiral shell.Again, the density of material of this cover body 30 is greater than the density of material of this body 20, to reach the lightweight advantage of open-end wrench.
Further, as shown in Figure 5, in an above-mentioned embodiment, if this operation width d (that is pulling mouthful 331 width) that pulls mouth 331 is larger, represent that the relative volume of this open-end wrench is larger, now the lightweight of this open-end wrench is more important.For example this is pulled operation width d of mouthfuls 331 and is equal to or greater than 32mm, more can highlight the present embodiment compound different material lightweight and maintain the advantage of pulling mouthful 331 desired stiffness.
In an above-mentioned embodiment, outer side edges 2112 parts with respect to this inner side edge 2111 of the fork 211 of this head 21 are exposed to outside this cover body 30, make to form the aspect of this first plate body 31 and the sandwiched fork 211 of the second plate body 32.Certainly, this second plate body of this first plate body of part and part may extend to the part that this holds portion 22, and to provide body 20 better distorting stress, and this holds portion 22 and also can be provided with at least one opening 221 (or fluting), to alleviate the weight of body 20.
The continuous Fig. 6 that please refer to, and simultaneously shown in Can Zhen Fig. 4, Fig. 5.The manufacture method of the open-end wrench in the present embodiment, comprises the following step: step S10, the body 20 of one first material is provided, and body 20 has a head 21 and and holds portion 22, and head 21 has a breach 212.Step S20, outside head 21, the cover body 30 of socket one second material, and make coated this breach 212 of this cover body 30, and the outer surface corresponding to this breach 212 of this cover body 30 forms one and pulls mouth 331, and this is pulled mouth 331 and unloads a screw terminal s in order to screw lock/spiral shell.Wherein, this cover body 30 and the socket mode of this body 20 can be applied gummed engineering method (but not being limited with this engineering method) for it.
In the manufacture method of above-mentioned open-end wrench, this head of this body and this hold that portion is integrally formed makes.
In an above-mentioned embodiment, this first material can be aluminium, magnesium or iron or its alloy, and this second material can be mould steel, chrome-molybdenum steel or chrome-vanadium steel.
In one embodiment of this invention, via above design, this body 20 with the first material (for example aluminium alloy) make, this cover body 30 for example, makes with the second material (chrome-molybdenum steel), after experiment, can commercial torsional moment require (643N-M) by the wrench standard of Deutsche industry norm (DIN) DIN-3113, reach 743.524～1141.639N-M, its weight expection alleviates 38～40% compared with clean steel wrench.
Feature of the present invention is, body of the present invention is that light-alloy material is made, and that cover body can be applied mould steel, chrome-molybdenum steel or high strength steel material is made, can utilize the body of light-weighted large volume, and the mouth of pulling of the cover body of high rigidity intensity contacts and acts on screw workpiece, recycling gummed processing procedure, by cover body be inserted in body engagement it, just estimate and can greatly reduce wrench weight.The present invention applies the design of different material and junction joint, and the ingenious reservation original material chief, after different material combination, can maintain the rigidity that spanner is pulled mouth, produces light-weighted advantage.
In sum, be that only notebook invention, for presenting embodiment or the embodiment of the adopted technological means of dealing with problems, is not used for limiting the scope of patent working of the present invention.Be that patent claim context all and of the present invention conforms to, or the equalization of doing according to the scope of the claims of the present invention change and modification, is all the scope of the claims of the present invention and contains.
