Abstract
The invention discloses a socket wrench, which can be simultaneously suitable for a British standard and a metric standard. According to the dual-hexagonal socket wrench disclosed by the invention, two conventional single-size sockets are replaced by a double-size hexagonal socket, and thus the number of sockets needing to be selected during the use is reduced; one hexagonal pattern of the dual-hexagonal socket wrench can be better suitable for matching elements in the metric standard, and the other hexagonal pattern of the dual-hexagonal socket wrench can be better suitable for matching parts in the British standard; and the two hexagonal patterns are better shifted into a 30-degree angle.
Description
Technical field
The present invention is mainly used in hand tools, particularly box spanner.
Background technology
When using conventional spanner to pull hex nut, opening must mesh one by one with six faces of nut.Known hexagonal socket wrench 10 shown in Fig. 1 has a hand arm 12 and a dismountable sleeve 14.Sleeve 14 contacts and forces in the circumferential surface at hex nut.Some die nut as shown in Figure 2, and do not require that spanner contacts the nut surface as much as possible, forming second hexagonal apertures through adjustment, the angle of this second hexagonal apertures extends to the midpoint of the first hexagonal apertures end.Because two hexagon lassos in this " two hexagonal configuration " can be applicable to the nut of corresponding size, the user uses the spanner of this class configuration, and how easier discovery is with correct being placed on the nut of spanner.This design is commonly called " bihexagon wrench ".
Automobile is assembled by the parts of country variant manufacturing often.Some country adopts amount weighing apparatus system made in Great Britain, and some adopts the metric system.Many machines are assembled jointly by the nuts and bolt of the metric system, size made in Great Britain.Conventional English system or metric system nut setter spanner, can only be applicable to nut or the bolt of specific dimensions, for satisfying in the different operating the requirement of the metric system, parts made in Great Britain, mechanic, machinist, electrician and consumer have to buy in the multiple types single head sleeve what set of tools.
Some commercial hand-held tools are designed to a difficult problem that is suitable for simultaneously different size English system or metric system nuts and bolt, as: open-end wrench, box spanner, changeable impact wrench, standard and angle box socket set (offset racheting box-end wrenches) and open sleeve spanner.But these instrument independent assortments, for nut or the bolt of different size, and applicable one or more specific standard.The both-end box spanner that shown in Figure 3 is produces according to prior art, front end be applicable to the bolt of a certain specification, the bolt of applicable another specification in rear end.
The U.S. the 5th, 048, what 379 patents were showed is the cubic transmission both-end sleeve that includes jackshaft, is connected and can uses with arbitrary end sleeve with traditional connecting rod.But this patent need to realize by movement, rotation and replacing sleeve the conversion of metric size made in Great Britain.In addition, this patent also needs to add connecting rod or special spanner when practical operation.
Except needs had the spanner of many sizes, machinist and other stakeholders often were difficult to determine accurate size when installation or removal nut or bolt, only by estimating to infer the spanner size that needs use.In addition, when servicing a car, often be difficult to judge that a bolt is English system or the metric system.Generally speaking, the machinist will attempt the sleeve of all size size before finding to be fit to the sleeve of bolt or nut size.They attempt could determining several times amount system and the concrete size of bolt possibly.If size that they have selected wrong, the sleeve size is little, and spanner unmatches certainly; If but sleeve select a little large a bit, spanner just uses relatively pine, as shown in Figure 4: the nut (NS) of the metric system 17 millimeters (0.669 inches) with 11/16 inch (A/F (H1) of 0.688 ") spanner unmatches the A/F H1=H2 of spanner.Because the hexagonal aperture H1 of spanner (entering face-to-face the footpath) surpasses the NS 0.019 of nut "; when rotating spanner (for example counterclockwise); only have its summit rotation when being slightly higher than the nut summit; and if only if the summit is in P point (but not surf zone of nut), the opening H1 of spanner could be meshed with the limit of nut.If spanner and nut are all made by hard material, can bear this rotatory force, nut just has been rotated.If but a certain material hard not (normally nut), so this size do not mate the transfer that can cause the summit, can cause the damage probability of (usually) nut to increase by 30%.

Summary of the invention
Describe in detail
The invention provides a kind of sleeve, can be suitable for simultaneously the bolt of two kinds of specifications that vary in size, reduce the required sleeve number of selecting when the nuts and bolt of assembly and disassembly various sizes.The sleeve of configuration can shorten nut or the bolt according to specific standard according to the present invention, determines the required time of just size sleeve.
Consider separately standard English size spanner, because its spacing is larger, the hexagon lasso is lower less than the chance of hexagon lasso cylinder outside this size within the inferior little size.The spacing of the spanner of standard metric size is larger equally.Yet if imperial sizing and metric size are compared side by side, two kinds of some sizes in measuring all only have trickle gap, and this is to mention the reason that causes the preferred dimension confusion in the discussion of background introduction.Teaching of the present invention utilize the advantage of 12 jiaos of both-end box spanners, be that they can be suitable for two kinds of nuts that size is slightly different simultaneously, one of them hexagon lasso is in order to mate the part of imperial sizing, and another hexagon lasso then is used for the part of coupling metric size.The design of the hexagon lasso of two kinds of different sizes allows the user only need a sleeve just can be suitable for the hex nut of two kinds of specifications.
Preferred embodiments of the present invention is included in the spanner perpendicular to rotating nut in the axial plane and bolt, this spanner comprises the sleeve with central shaft, and the cylindric opening that centers on axle, this opening has along the side of the greater in the first hexagon and the second hexagonal girth, and this second hexagon is offset from the axle that the first hexagon centers on.
Advantage of the present invention is the use of two size sleeves, can reduce the number of times that the user changes instrument, accelerates its maintenance speed.
Shown in Figure 5 is the view such as survey such as axle such as grade of one of example of the present invention box spanner 20.Box spanner 20 comprises receiver 22, although can select arbitrary shape, substantially tends to select cylindrical seat.Receiver 22 front ends 24 are nut opening 26, and the sleeve in the example is detachable, and its rear end (invisible) is by being connected connected mode and shown in Figure 1 similar such as square sleeve joint 28 or other apertures etc. with the hand arm 12 of spanner.The hand arm of spanner is transferred to receiver 22 by connectivity part with moment of torsion, turns to outer hexagon lasso 31 and interior hexagon lasso 32 again.The muff joint of other kinds or shape also can provide moment of torsion to sleeve.The muff joint of other kinds or shape also can provide moment of torsion to sleeve.In another example of the present invention, for example be similar to one of existing spanner shown in Figure 2 can not break the box spanner of (non-detachable) can be integrally formed with hand arm, and do not need other joint.
As shown in Figure 6, nut opening 26 is round the rotating shaft X of sleeve 20, and take with central axes, comprise the inner surface 32 of 24 side F as the boundary.Can alternately form between the adjacent side on the occasion of angle (clockwise 60 °) and negative value angle (counterclockwise 30 °).Each take V as the summit, forms a bag zone (pocket) P with adjacent surface on the occasion of the angle.The set Pouter in first group of bag zone comprises each other the bag zone on the border (being connected by dash between each bag zone) of definition first hexagon pattern H1.The set Pinner in second group of bag zone has then defined the border (being connected by dotted line between each bag) of second hexagon pattern H2.In known single size box spanner, the equal and opposite in direction of two hexagon patterns forms 30 ° of angles along X-axis; According to the spanner of the present invention's design, opposite side distance H1, the H2 of its hexagon pattern are unequal, and go for the nut of different size.
Shown in Figure 7 is the dimensional drawing of one of example of the present invention box spanner 20: it has larger outer hexagon lasso opposite side distance (HS
L) and less interior hexagon lasso opposite side distance (HSs).The preferred plan of inside and outside hexagon lasso is to intersect angle along X-axis

According to the present invention, above-mentioned size can be used for determining how to make up the sleeve of different size, consists of the spanner of all size.It is enough large that the matching surface F of hexagonal socket wrench and nut wants, and could entangle and rotate hex nut when not damaging the bolt angle.The opposite side distance HSs of interior hexagon lasso is reduced, and its hexagon lasso summit spacing PHDs also can shorten, and the identical length of spanner and nut and the area that coincide also can correspondingly reduce.(by contrast, if the opposite side distance HSs of hexagon lasso in reducing, the summit spacing of outer hexagon lasso then can increase, and also can correspondingly enlarge with the identical area of nut, is illustrated in fig. 12 shown below.) the two die nuts of the single size of standard of interior hexagon lasso H2, and to reach 80% at least with the desirable identical area of the outer hexagon lasso of size.In other words, the I columns value shown in Fig. 8,9,10,11 preferably is no more than 20%.The actual alternative that surpasses the optimal case of minimum dimension of interior hexagon lasso opposite side distance is the F columns value shown in Fig. 8,9,10,11, and namely interior hexagon opposite side distance is not less than 97% with the ratio of outer hexagon opposite side distance.
The metric size of the interior hexagon opposite side distance of the imperial sizing of the outer hexagon opposite side distance of A row shown in Figure 8 and D row, be used for being combined into two size box spanners, whether whether the J row chosen then feasible to mating, for example, eighth row coupling is the sleeve of 11/16 inch and two close sizes of 17mm among Fig. 8: 11/16 inch (A columns value) equals 0.688 inch (B columns value), and 17mm (D columns value) equals 0.669 inch (E columns value); So 11/16 inch is larger, become outer hexagon opposite side distance HSL (A columns value), 17mm becomes interior hexagon opposite side distance (D columns value).Apply mechanically top formula, interior hexagon opposite side distance is 97.4% with the ratio of outer hexagon opposite side distance, satisfy to be not less than 97% preferred value, the analysis of example according to the present invention, choosing also of eighth row J row shows: 11/16 inch of eighth row and 17mm can be used for being matched to two size box spanners.
The imperial sizing of the interior hexagon opposite side distance of the metric size of the outer hexagon opposite side distance of A row shown in Figure 9 and D row, be used for being combined into two size box spanners, whether whether the J row chosen then feasible to mating, for example, that the 7th row coupling is outer hexagon lasso H1 opposite side distance HSL13mm (A columns value) among Fig. 9, interior hexagon lasso H2 opposite side distance HSS0.5 inch (E columns value), and 13mm equals 0.512 inch (B columns value) is only than 0.5 large 0.012.First group of hexagon lasso is applicable to the screw bolt and nut of 13mm specification, and second group of hexagon lasso is applicable to the screw bolt and nut of 0.5 inch specification.
In addition, shown in Figure 10,11 tabulation, the hexagon lasso of two close English systems or metric size also can be combined into two size box spanners.The ratio value that does not have the combination of two imperial sizings or two metric sizes can satisfy the F row among Figure 10 and 11 be higher than 97% or the ratio value of P row be lower than 20%.But 11/16 inch sleeve difference with 11/8 inch is little, so the practicality that two English system and two metric system are combined in the large size sleeve is higher.
As mentioned above, if the opposite side distance HSs of hexagon pattern in reducing, the summit spacing of outer hexagon pattern (point to hex distance, PHDL) then can increase in surpassing the first summit spacing HRL, also can correspondingly enlarge with the contact area (SCL) of bolt.Therefore, the opposite side distance of interior hexagon H2 is less, and the rotatory force that the outer hexagon H1 of spanner produces is larger.As shown in figure 12, even falsely drop the spanner of applicable opposite side distance 17mm specification nut, the contact area SC of increase (Surface Contact) is apparently higher than the single size spanner of general applicable 11/16 inch specification nut.When inside and outside hexagon lasso intersects angle along X-axis
The time, the rotatory force of spanner reaches maximum, but other angles are feasible equally.
If bolt, nut and box spanner are all made by hard material, the proportion that hexagon summit pitch difference accounts for normal pitch preferably be not higher than 20% or when outer hexagon lasso opposite side distance HSL may be greater than among Figure 10 the 7th, 12, in the 8th to 18 row during matching value of listed pair of size Hexagonal jacket, the ratio that interior hexagon opposite side distance accounts for outer hexagon opposite side distance is not less than 97% among 13 row and Figure 11.As shown in figure 13, the theoretical maximum difference of inside and outside hexagon size or the theoretical minimum dimension of interior hexagon lasso are when interior hexagonal diagonal line length HDs equals outer hexagonal radius HRL, and outer hexagonal radius HRL equals outer hexagon diagonal line length and multiply by sine60 °.Only work as inside and outside hexagon lasso and intersect angle along X-axis
The time, (HDL) * (86.6%) just can obtain theoretical extreme.
Shown in Figure 14 is the two hexagonal socket wrenches 140 of one of example of the present invention both-end, applicable to bolt or the nut of four kinds of different sizes.One end of this spanner 140 forms the bolt of applicable two kinds of sizes by two size sleeves 141 and 142; The other end is comprised of two size sleeves 143 and 144, also can be used for the bolt of two kinds of specifications that vary in size.
According to example proposed by the invention, in practical field, those of ordinary skills can do corresponding modify according to the invention thinking.For example, if select inside and outside square sleeve, according to the square spanner of the present invention design equally applicable to square screw bolt and nut.Therefore, following claim contains all and meets this theory to what invention was made, belongs to the modification of invention scope and spirit.
