Description
The present invention relates to a kind of screw that is used for complete meccano, this screw is made of a threaded body of screw, in another parts of the complete meccano that described screw thread can be screwed into screw to have a prefabricated tapped hole, so that screw can bear the effect of the power of a body of screw that laterally acts on screw apart from a certain distance of these parts.
With regard to the complete meccano of structure type, it is well-known together that each parts is screwed in.So some examples show, except common connection means (such as connecting bolt and complementary receiver member), the parts that the are subjected to the specific load effect also screw of available special manufacturing couple together.Can be screwed into these screws in the specific pre-threaded hole in other combiner of complete meccano.Same well-known be wheel to be fixed on the vehicle chassis with the component-assembled of complete meccano with screw.With regard to this car, the connection situation that strengthens mutually between each parts is entirely satisfactory.In its vertical absorption, and the tension force absorbability of screw are entirely satisfactory such load by screw.Such screw can be seen in the document such such as US Patent specification 455/110.
A kind of screw that hinders the flexibility of relevant parts is disclosed in the Danish Patent Application 872/89.Herein, stress is that the footpath that is added in screw makes progress equally.
But, load laterally is added to body of screw screw radially a significant disadvantage.The diameter of the helical thread portion of screw is determined by the size of the parts that this screw put in.With regard to general structure, often make the size of these parts as far as possible little, make the diameter of helical thread portion also as far as possible little like this.Affact the moment on the screw, part is by the size decision of the cross stream component that affacts the power on the screw, part is decided by the distance between the point of action of power and the point of contact (screw just is fixed on these parts, and described power just acts on the arm of these parts) that has the body of screw of above-mentioned parts.For example, require the diameter of helical thread portions less, so be subjected to big dead load or such as being subjected under the situation of sudden surge, these screws tend to damage in the zone around the above-mentioned parts surface when screw when falling as those screws of wheel shaft.If when conducting the laterally suffered power of this screw, corresponding problem will occur with screw.
So, the purpose of this invention is to provide a kind of screw that is used for complete meccano, the structure of described screw make it to bear better the y direction that laterally is added to screw and with complete meccano in the screw of those parts at a distance of the effect of the power of a certain distance, wherein said screw is located in the prefabricated tapped hole in the complete meccano.
The objective of the invention is to realize by the mode described in the characteristic of claim 1 because require when determining the position (its radial distance is bigger than the radius of helical thread portion) of engaging zones the moment that produced owing to the arm of force that is produced reduce reduce.
In a preferred embodiment, engaging zones is made of a conical engagement face on the screw.The conical engagement face preferably forms on the parts of wherein placing screw by a corresponding conical engagement face is connected to.Conical engagement face on the screw helps having formed a transition zone at the helical thread portion of minor diameter and diameter between the body of screw part greater than described diameter.It is suitable especially that this is not subjected at latter's diameter under the situation of any restriction.
Usually two conical engagement zones on screw and the combiner are preferably complementary respectively, but engaging zones can for example be annular, and can form like this, promptly form screw by progressively expanding.Concerning most of plastic materialss, sharp edges like this has caused this structure to exist shortcoming (groove effect) in above-mentioned sharp edges peripheral region on the plastic construction.Therefore, preferably use the conical engagement face in the reality.
Because complete meccano is normally produced with the plastic injected die method in a preferred embodiment, the pitch of screw thread is bigger usually, so the mating face preferably is made of the depression and the projection of complementation, when depression and projection when engaging, screw just remains on its insertion position like this.This when used screw be suitable especially when a wheel shaft because lean against the effect that the screw of a side of the car that it is placed in one can be subjected to the power that a wheel hub friction with wheel produced, in other words, cause that screw is lax or become tightly.And just can avoid this problem with the depression and the projection of above-mentioned complementation.Can suitably shape projection is a round knot.Can make depression asymmetrically, make it to have the guide surface of a steep stop surface and an inclination.Even these characteristics can make screw only do under the situation of an about circle screw thread, also can obtain sufficient maintenance thereon.Therefore, can only make screw by injection molding with simple tools.
The contact preferred embodiment will be narrated the present invention also with reference to the accompanying drawings below in more detail, in the accompanying drawing:

How Fig. 7 illustrate the perspective view of a screw of the present invention among a wheel hub is put into another combiner of complete meccano,
Fig. 8 is a kind of schematic representation of alternative layouts of the interlocking of screw of the present invention and tapped hole.
Fig. 1 shows one according to screw of the present invention.It is made of a screw head 12 that has the body of screw, and a helical thread portion 24 is arranged on the body of screw, and helical thread portion 24 has a screw thread 25 at the end away from screw head 12.Helical thread portion 24 ends at downwards and has two just in time tapering parts 22 of the opposite locking aperture 23 that is provided with.Tapering part 22 constitutes a profile line part between the remaining part of the body of screw of the bigger screw of the less helical thread portion 24 of diameter and diameter.Screw 10 of the present invention is preferably by the plastic injected die manufactured, and therefore normally hollow.So, screw 12 and conical surface 22 between the diameter of body of screw part 14 bigger than helical thread portion 24.There is one on the body of screw part 14 by guide surface 21 and the annular flange 19 that stop surface 20 constitutes.In a preferred embodiment, the body of screw 14 merges into a body of screw part 16 by a tapered guide face 15, and the diameter of body of screw part 16 is identical with the diameter of crimping 19.
Because the shape of screw 10 as shown in fig. 1, a wheel hub 40 shown in Fig. 7 can be mounted and rotatably be fixed on the body of screw part 14, and body of screw part 14 is between crimping 19 and 12.Guide surface 21 allow such acceptance and simultaneously prevent surface 20 can prevent that wheel hub 40 from deviating from.Guide surface 15 and body of screw part 14 are corresponding to the hole in the wheel hub 40, and described hole and complementary guide surface (not shown) advantageously are recessed into respect to the outside of described wheel hub, thereby in assembly process, between each parts, reach better guiding effect.
On the screw 10 12 preferably has some grooves longitudinally, so that when screw 10 is screwed into another parts, can hold more firmly.As shown in Figure 7, the end face 11 of screw head 12 has an opening, and this opening is suitable for accepting a special instrument that is used for tightening screw.How screw is suitable for being installed in the tapped hole 35 on another parts 30 that are contained in the complete meccano if being shown among Fig. 7, described tapped hole 35 has a tapering part with tapering part 22 complementations of screw, and two just in time opposite locking projections portions 37 that are provided with are arranged on this tapering part.These locking projections portions 37 are preferably the shape that little rotation symmetry saves, and those holes 23 are asymmetrical shape.Like this, these holes will have a guide surface that is used for locking projections portion 37 guiding is advanced jointing state, and one is hindered further fastening stop surface.Especially be flexible because of material, and the pitch of screw thread 25 is bigger, so this is possible.Clearly, concerning the professional and technical personnel, can also make screw have some locking projections portions, make the tapering part 36 on the parts 30 of meccano have some complementary locking apertures simultaneously.
Suggestion is used for multiple other purposes to screw rather than sticks to outmoded conventions ground as wheel shaft, but principle of the present invention has probably still obtained best embodiment on described Placement.Can regard the car that is assembled into by complete meccano as constitute object by several independent inferior bodies (subbody).For example, these inferior bodies can comprise each in the actual vehicle chassis that has superstructure and four wheels.Do the time spent when whole material is subjected to a load that causes such as the whereabouts, between each overall inferior body of formation, torsion can occur.Falling load between action period, and these power are converted into the moment that acts between each inferior body.Described moment depends in part on the size of power, depends in part on the arm of force that is acted on.Because the engaging zones (tapering part 22 among Fig. 1) of screw is bigger than the radius of helical thread portion 24 apart from the radial distance of the screw longitudinal axis, the point of action of power will move on to from the terminal 22a of helical thread portion on the transition zone 22b between conical region 22 and the body of screw part 14.The size of the arm of force that is acted on will reduce thus, and simultaneously point of action 22b will act on screw pulling force longitudinally changing one in distance combiner 30 a certain distances into along a bending force of the horizontal effect of screw 10.
Fig. 2 shows a preferred embodiment of screw of the present invention, wherein is furnished with the engaging zones 22 of a taper between the remaining part of the body of screw 14 of the helical thread portion 24 of screw and screw.Screw is screwed into parts 30, and like this, screw just is received and remains among tapped hole 30 and the scyewed joint 42.Owing to relate to the conical region 22 and 36 of two complementations, so the engaging zones of screw also will be continuous conical surface.But, between two faces a slit is often arranged in the reality, but, just can be pressed onto 22 and 36 together with mechanical external force because screw has flexibility.
Fig. 3 shows another embodiment of screw of the present invention, and screw is scyewed joint by helical thread portion 24 with the helical thread portion of tapped hole 35 among the figure.Can see that the body of screw 14 of screw is identical with the diameter of the helical thread portion 24 of screw.By a crimping 41 that has some conical surfaces (mating face 22 is exactly one of them) off-load takes place herein.Tapped hole on the parts 30 stops in the mode of progressively expansion, and this makes that herein mating face is that Line of contact 37 by an annular constitutes just.Because point of action 22b is positioned on the Line of contact 37, so embodiment is basic identical shown in the technique effect that present embodiment provided and Fig. 2.
Can think complementary structure shown in structure shown in Fig. 4 and Fig. 3, this is because tapped hole 35 herein has tapering part 36, is progressively transition simultaneously between the remaining part of the body of screw 14 of helical thread portion 24 and screw.An annular contact line 37 is also arranged herein, and point of action 22b is located on this line.Screw will engage with combiner by scyewed joint 42.
Fig. 5 shows a screw, and wherein the mode that progressively increases with diameter of helical thread portion 24 merges into the remaining part 14 of the body of screw of screw.Arrive just as seen in Fig., the diameter of tapped hole 35 will keep constant once the surface that goes out above-mentioned parts, and this makes capable release engaging zones 43 be done into dish type, and actual point of action 22b will be arranged in the outward edge of dished region 43.
Fig. 6 shows a kind of structure corresponding to the structure shown in Fig. 5, wherein point of action 22b again further away from each other the longitudinal axis of screw thread, have an annular portion 38 on the body of screw part 14b, to strengthen the width of dish type engaging zones 43.Herein, screw also will link by the tapped hole of scyewed joint 42 with parts 30.For the embodiment shown in Fig. 4 to 6, the helical thread portion 24 of screw all is the helical thread portion 14 that merges into the body of screw in the mode that diameter progressively increases.But should be noted that the intensity of the body of screw of screw in this zone can be owing to the groove effect reduces.
Fig. 8 shows an alternative embodiment of screw shown in Fig. 1, and wherein the helical thread portion 24 of screw merges into the body of screw part 14 of screw by a tapering part 22.The combiner 30 that has been screwed into screw has a tapped hole 35, and this hole equally also has a tapering part 36.Screw links by scyewed joint 42 and combiner 30, also fixing in addition between screw and this parts by pair of locking projection 39, these projectioies are located among the depths of tapped hole, and are adapted to be received among the end of the screw in two locking apertures 43 that there constituted.The power that a wheel produced that has guaranteed thus to be contained on the screw can not make screw thread become flexible with respect to combiner 30.On the other hand, this also can have than large screw pitch because of screw thread 25 and realizes.Pitch is more greatly at when recreation mounting screw and for the ease of making screw more easily, only makes and just can make it with simple tools
