Description
Technical field
The present invention relates to a kind of helical element, for example screw, nut, sleeve part, pipe plug, tube connector etc., this helical element has the screw thread that is positioned on the matrix and at least one circumferential seal (for example O shape ring) and/or at least one screw thread safty device, described screw thread safty device have improved described helical element when existing spiral to be connected between described helical element and another member the torque of outwarding winding.
Background technique
This screw thread safty device that are used for screw or helical element are known.For example, in a kind of known safty device of aforementioned type of introducing to the market as ProductName, milled out a groove in the screw thread of screw matrix, and in this groove, be pressed into the line of an energy resiliently deformable with Klemm-tight (TM trade mark).Used the line that constitutes by a kind of carbon fibre core especially at this with plastic casing.When helical element and another member formed spiral and be connected, this line had improved the torque of outwarding winding of described helical element.Circumferential seal, for example O shape ring has at first been realized sealing function, simultaneously, its existence can also reach the secondary function of the torque of outwarding winding that improves helical element.
The fact shows that the known helical element that adopts the described type of beginning is not that a kind of long-time spiral reliably of total energy formation connects.In addition, adopt the cost of extraordinary line also very high.
Summary of the invention
The helical element that can be produced with minimum technology cost that basic order of the present invention is to provide a kind of this paper to start described type, this helical element guarantee with another member form a kind of for a long time highly reliably spiral be connected.In addition, this helical element also should be able to be assembled when setting up the spiral connection at an easy rate, and its functional safety should be able to be kept under the effect such as environmental factors such as temperature, pressure.
According to the present invention, the purpose of above-mentioned helical element about described type is achieved by following manner, that is, adopt by the hetero-polymer material with multi-part injection molding technological forming and matrix connected to one another and circumferential seal and/or screw thread safty device.
Helical element is according to this structure of the present invention, make it can be in an advantageous manner fully only in a processing machine or mould die casting form, wherein, according to the number of assembling steps of prior art needs designs, milling groove and itself and the step that wire safty device of processing separately are assembled together can be saved for example.In addition, connection by a kind of material fit (stoffschluessig), such as the connection that forms with multi-part injection molding technology, can a kind of very stable and reliable connection of formation between the matrix of helical element and circumferential seal and/or screw thread safty device.
Described matrix preferably can be made up of thermoplasticity or thermosets respectively, and screw thread safty device and/or circumferential seal are formed as thermoplastic elastomer (TPE) preferably by one or more elastic materials.For matrix, especially preferred material is polyoxymethylenes (POM) or polyamide (PA), particularly fibre-reinforced polyamide, and for screw thread safty device and/or especially preferred silicone rubber of circumferential seal and/or fluorine rubber (FKM, MVQ, FVMQ), but also available ethylene propylene diene rubber (EPDM) and/or polyurethane (PUR), for example thermoplastic polyurethane (TPE-U).
Injection molding (English: injection molding) be a kind of discrete basic forming method that is used for plastics.Utilize injection molding, can make in large quantities the direct applied moulded parts of industrial energy with higher precision.For this reason, corresponding material moulding material is in other words processed by plasticizing in an injection unit of injection molding machine, and is injected in the injection molding mould.Modern injection molding machinery utilization screw rod carries out work, and this screw rod is plastified moulding material processing, carries and injects among the mould.In other words in the moulding cave, polymer material is solidified, and profiled member can be taken out from mould thus at the chamber of mould.The situation of the volume-diminished that occurs when solidifying can be remedied by the mode that imposes dwell pressure (Nachdruck) before taking-up to a certain extent.
By injection molding, can be to thermoplastic, thermosetting plastics and elastomer are processed.Here, when thermoplastic is carried out injection molding, can adopt the material that comprises fiber, can produce thus and have more high-intensity profiled member relatively.As fiber, can consider to adopt isotropic fiber, for example glass fibre, and/or anisotropy fiber, for example carbon fiber or aramide-fibre.When injection molding, material temperature is approximately 100 ℃ to 350 ℃, and jet pressure is approximately 400 to 1600 crust, and die temperature is approximately 40 ℃ to 160 ℃.When the processing thermoplastic plastics, screw rod is quite warm, so that molten thermoplastic material.In contrast, mould is quite cool, so that the profiled member that cooling has just generated.When processing thermosetting plastics, the temperature of plasticization unit and stream curing action
Be complementary, therefore lower than the temperature when the processing thermoplastic plastics usually, and for injection unit, it is hotter that mould must be held, so that material can be solidified at this.
Elastomeric injection molding is equally preferably implemented in screw type injection molding machine.Elastomer is can be with (rieselfaehig) that can flow Powdered or be banded ground and drawn in by a special screw rod, and described screw rod imposes shearing to plastifying material hardly.Cylinder is regulated temperature with liquid usually, to avoid overheated.Processing temperature is approximately 70 ℃, to prevent that vulcanization reaction takes place in cylinder.Do not consider aforementioned special way, similar on the injection molding process principle of this moment with the injection molding process that thermoplastic is carried out.Screw rod kneads moulding material and mixes, and thus its preprocessing is become even shape.For example compare, can reach the purpose of the quantity of sintered parts that improves manufacturing, because in die pressing, because the heat of outside input can make temperature distributing disproportionation even by said method with die pressing.And course of working is also carried out relatively soon.Can produce frictional heat when in jet pipe and casting pipeline, flowing.This has shortened to carry out the necessary needed time of vulcanization reaction in elastomer.Therefore, the operation process of injection molding is very economical.Compare with the elastomer of being made by mold pressing, more elastomeric mechanical propertys of making by injection molding can exceed 30%.High viscosity of material requires big relatively cast gate cross section.When the elastomer injection molding, often be that a plurality of moulds and different piece adopt the injection molding machine with a plurality of linkage units (Schlie β einheit), because the vulcanization reaction time obviously is longer than the preprocessing time in injection unit.This makes elastomeric injection molding especially economical.
Especially can know thus, if matrix and circumferential seal and/or screw thread safty device are made by the hetero-polymer material, for example, matrix is made by thermoplastic, circumferential seal and/or screw thread safty device are then made by elastomer, so this manufacturing can only realize with multi-part injection molding method in a machine at an easy rate, in described multi-part injection molding method, the injection molding step of thermoplastic and elastomeric injection molding step take place each other in succession.
Special thread safty device according to helical element of the present invention, its salient point that is different from known screw thread safty device is, it is not to be made into line, but by the multi-part jet moulding, perhaps two parts jet mouldings and be manufactured into parts made from helical element especially.At this moment, be used to hold the one or more of screw thread safty device and/or circumferential seal in the described helical element, particularly the groove that axially and/or radially extends can be in the injection molding process of described helical element with technics on favourable mode do not have cutting ground moulding.
Only by unique screw thread safty device, just can realize compensating screw thread and the tolerance of another member and the purpose that improves anti-seismic performance of helical element, thereby can prevent the situation that occurs unclamping when spiral between helical element and described another member is connected variable load effectively.This is by being achieved screwing in such clamping action that is produced by the resiliently deformable of screw thread safty device when strengthening helical element.At this moment, especially the gap between the internal thread of the outside thread of helical element and another member can be by the filling of screw thread safty device, so the screw thread safty device have reached the purpose that improves surface pressure between the thread contour respect to one another side.
One connection all can be unclamped at any time although it is so, even if but the reliability that this reinforcement connects still must keep after repeatedly screwing in and screwing out.Therefore prevented to take place automatically down in working order to become flexible and unclamp according to helical element of the present invention.
Other favourable DESIGNED FEATURE of the present invention are included in each dependent claims and the explanation subsequently.

In addition, helical element 1 according to the present invention has the screw thread safty device 6 that are used for screw thread 3, and described screw thread safty device 6 have improved the torque M L that outwards winding of described helical element 1 when existing spiral to connect between helical element 1 and another member.Above-mentioned another member that is connected with helical element 1 spiral is not shown in Figure 1, but for example is illustrated among Fig. 3 to Fig. 5, and with reference character 8 signs.Salient point according to the screw thread safty device 6 that are used for screw thread 3 of profiled member 1 of the present invention is, it perhaps manufactures parts that are manufactured in together with profiled member 1 with two parts injection molding process quilts especially with multi-part injection molding technology under the situation of present embodiment.Therefore it is the mode to stick, and that is to say that the mode of material fit is connected on the matrix 2.In addition, also can select to be designed to the connection of form fit.For processing, can defer to the foregoing process conditions that are used for injection molding.
Screw thread safty device 6 have length L E, and in the example that illustrates, this length L E extends on the whole length of screw thread 3.Certainly, it also can make shortlyer.The cross section of this annex is essentially rectangular shape, but this is not a limited features.The length L E of screw thread safty device 6 is than its cross-sectional dimension, i.e. height H E and the big manyfold of width B E, wherein, the order-of-magnitude agreement of the pitch height H G of the order of magnitude of cross-sectional dimension HE, BE aspect and screw thread 3.
Can adopt plastics, for example unfilled (ungefuellt) polyamide (PA) is made screw thread safty device 6.Also can be used in the material of making Sealing but especially advantageously adopt, that is to say, one or more elastomeric materials especially, promptly a kind of preferably not fibre-bearing, isotropic material, for example thermoplastic elastomer (TPE).As previously mentioned, particularly preferred material be fluorine rubber and/or silicone rubber (FKM, MVO, FVMQ), but also available ethylene propylene diene rubber (EPDM) and/or polyurethane (PUR), for example thermoplastic polyurethane (TPE-U).
One especially axially extended is used for the groove 7 that form fit ground holds described screw thread safty device 6, can be when the described helical element 1 of injection molding with technology on favourable mode do not have cutting ground moulding.Described groove 7 should have degree of depth TN, and this degree of depth TN is approximately the same big with the height H E of screw thread safty device 6, but preferably slightly little, so that screw thread safty device 6 stretch out the flank of thread of screw thread 3 a little.
By unique screw thread safty device 6, just can realize compensating the screw thread 3 and the tolerance of the screw thread of another member and the purpose that improves anti-seismic performance of helical element 1, like this situation that occurs unclamping when having prevented that spiral between helical element and described another member is connected variable load.Fig. 3 to Fig. 5 shows the stubborn situation of closing according to helical element 1 embodiment of different embodiments of the invention, and wherein, as previously mentioned, another member that is connected with helical element 1 spiral is with reference character 8 signs, and the screw thread of this another member is with reference character 9 expressions.
Aforementioned functional is by being achieved screwing in such clamping action that is produced by the resiliently deformable of screw thread safty device 6 when strengthening helical element 1.At this moment, the gap between the internal thread 9 of the outside thread 3 of helical element 1 and member 8 can be by 6 fillings of screw thread safty device, so screw thread safty device 6 have reached the purpose that improves surface pressure between the flank of thread respect to one another.
As required, can on the matrix 2 of helical element 1, two or more (being provided with 4 in Fig. 1) screw thread safty device 6 be set for this purpose with symmetry or asymmetric arrangement.The arrangement of symmetry only works by the mode that increases frictional force, and asymmetric arrangement can make helical element 1 produce wobbler action in the member 8 at its screw-in extraly when screwing in; That is to say, after screwing in, the axle of helical element 1 and a no longer coaxial extension of member 8.
One connection all may be unclamped at any time although it is so, has still kept its reliability after still this reinforcement is connected and repeatedly screws in and screw out.Therefore prevented from automatically to take place down in working order to become flexible and unclamp according to helical element 1 of the present invention.
In addition, connect the various requirement that is determined by operating conditions for spiral, the insurance function of screw thread safty device 6 all can adapt in an advantageous manner with the screw-in torque.
Fig. 2 show according to the different embodiments of helical element 1 of the present invention they separately with another one member 8 (twisting with each helical element 1 and closing form stubborn and close centering and all adopt same member 8) between spiral be connected when being outwarded winding the outward winding contrast figure of torque M L of the difference that helical element 1 is had.
In the drawings, as a comparison, column G1 relates to a non-helical element of the present invention, and this helical element does not have the screw thread safty device.
Column G2 relates to a helical element 1 with the circumferential seal 10 that is configured to O shape ring as shown in Figure 3.Can see that with respect to a helical element that does not have this circumferential seal and do not have other safty device, O shape ring 10 has improved the torque M L that outwards winding, that is to say that it has played the effect of screw thread safty device 6.
Column G3 relates to a kind of embodiment as shown in Figure 4, promptly relates to a kind of circumferential seal 10 that is configured to O shape ring that both had, and has the helical element 1 of screw thread safty device 6 extra, that particularly made by polyamide again.The torque M of outwarding winding L has had further lifting.
Column G4 relates to a kind of as Fig. 4 or embodiment shown in Figure 5, and wherein, screw thread safty device 6 or assembly parts 11 comprise O shape ring and the screw thread safty device of being made by elastic material.Assembly parts plays the effect of circumferential seal and screw thread safty device simultaneously.According to the specified value SW of the predetermined torque M L that outwards winding, for example 3 to 4Nm, can select targetedly.
In addition, for the torque M L that outwards winding, also can be regulated by the physical dimension and the configuration mode of screw thread safty device 6 or assembly parts 11.According to the present invention, all parts 6,10,11 (perhaps, in Fig. 4, having only some parts wherein) can be molded with matrix 2 in multi-part injection molding technology by different polymer materials, and be connected to each other together.
Shown in Figure 5 is configured to annular by O shape ring and the integrally formed assembly parts 11 of screw thread safty device, and have an O shape loop section 12 and one and be molded in big envelope part 13 on this O shape loop section 12 with cylindrical form, described O shape loop section 12 has the cross section of the circle of being similar to, and for big envelope part 13, just as appreciable from accompanying drawing, the basic shape in its cross section is similar to rectangle.Big envelope part 13 can also have the fluting of an X-X extension in axial direction.The axial length L K of assembly parts 11 can preferably be equivalent to 2 to 4 times of average diameter of O shape loop section 12, and wherein, the latter can be according to being used to select O shape ring taps rope diameter
The industry universal standard select.Assembly parts 11 preferably with Fig. 3 and embodiment illustrated in fig. 4 in the similar mode of O shape ring 1O, be installed in a groove 14 on the flange portion 4 that is arranged in profiled member 1 along extending circumferentially, bottom surface, wherein, under the state that assembling finishes, the big envelope part 13 of assembly parts 11 should extend on several initial (top in Fig. 5) pitch (Gewindegang) of screw thread 9 of member 8 at least, and these initial pitch are that profiled member 1 is threaded in those pitch wherein.
Fig. 6 and Fig. 7 show other embodiments according to helical element 1 of the present invention, and these embodiments are configured with outside thread 3 equally, and still, these outside threads 3 also serve as the female part that is used to form socket connection on the other hand simultaneously.These two kinds of embodiments only have an a shade of difference in shape at the flange portion 4 of helical element 1.There is shown its respective insert, and it is identified with reference character 15.These two kinds of embodiments also have screw thread safty device 16, to be used for being threaded 3/9 between helical element 1 and its member that is screwed in 8.
Screw thread safty device 16 are different from those at the screw thread safty device 6 shown in Fig. 1 and Fig. 4 on structure and function.If Fig. 1 and screw thread safty device 6 shown in Figure 4 have the more static mode of action of possibility, then the mode of action according to each screw thread safty device 16 of Fig. 6 and embodiment shown in Figure 7 is dynamic, in other words, screw thread safty device 16 are the time marquis of assembling, when especially between female part and inserting member 15, forming socket connection, can carry out the transition to state of activation from unactivated state.Fig. 6 shows the state of activation of screw thread safty device 16, and Fig. 7 shows its unactivated state.
Fig. 6 and embodiment's shown in Figure 7 screw thread safty device 16 are configured to the pin shape respectively, and wherein, the safty device body of this pin shape is also as above-mentioned screw thread safty device 6 or assemblying body 11, are to be made by a kind of material that can resiliently deformable.Screw thread safty device 16 pass the radial opening 17 of the wall body 18 of helical element 1, therefore are placed in movably in this radial opening.This just needs, and screw thread safty device 16 are not with matrix 2 moulding and linking together in multi-part injection molding technology.However, but O shape ring 10 can make by a kind of like this processing method.But, no matter the embodiment of O shape ring how, a kind of so dynamic structure of screw thread safty device 16 has innovative significance, also shows a kind of so dynamic structure in Figure 24, and the screw thread safty device shown in the figure can carry out the transition to a kind of state of activation from a kind of unactivated state.
A transition fit that plays clamping action can be arranged between screw thread safty device 16 and radial opening 17, thereby make screw thread safty device 16 avoid from described radial opening 17, deviating from.At this moment, screw thread safty device 16 have a radial length LS, and this radial length LS will be a bit larger tham the wall thickness LW of the wall body 18 of helical element 1 in its radial opening 17 scopes and the height H G sum of screw thread 3.
Shown in Figure 7 is in the unactivated state, and screw thread safty device 16 radially inwardly extend in the admittance opening 5 of helical element 1.But, when inserting member 15 when its direction of insertion S inserts, screw thread safty device 16 can be inserted into the conical surface 19a radially outward extruding of part 15, thereby activate the function that torque M L is outwarded winding in its increase.Here, can be designed so that preferably that the screw thread safty device resemble at inserting member 15 is just activated when arriving its final rigging position in female part shown in Figure 6 fully.Therefore, the feature of the state of activation of screw thread safty device 16 is that especially screw thread safty device 16 are further outwards pushed in radial opening 17, so that it exceeds the helical element height H G of the screw thread 3 of female part 1 in other words, perhaps flushes with height H G at least.In order to reach such purpose, can on inserting member 15, correspondingly dispose a diameter and enlarge district 19b, like this, member 8 be screwed to profiled member 1 be configured on the externally threaded screw thread 3 time, this enlarged-diameter district 19b can stop screw thread safty device 16 inwardly to be pushed once more in radial opening 17.In order to act synergistically ideally with screw thread safty device 16 and in order to make inserting member 15 axial motion in the clear in the admittance opening 5 of helical element 1, the enlarged-diameter district 19b of inserting member 15 is same preferably by made that can resiliently deformable.For a plurality of positions of implementing the screw thread safty device in the above are set, can in the injection molding of described helical element 1, introduce or after injection molding, get out radial opening 17 or a plurality of radial opening 17 equally.
Demonstrate in other embodiments shown in Fig. 8 to Figure 10 according to helical element 1 of the present invention, groove 7 and the equipment that improves the torque M L that outwards winding, just safty device 6 or circumferential seal 10 can be extended on the matrix 2 of helical element 1 in a different manner.Every kind of extension can be intersected (referring to Fig. 8,9) or extend (referring to Figure 10) with pitch almost parallel ground with different angle μ with pitch.In addition, in Fig. 8 and embodiment shown in Figure 9, groove 7 and screw thread safty device 6 on the matrix 2 of helical element 1 various extensions and the screw-in direction ER of helical element 1 in the same way or reverse.By selecting corresponding direction and angle, can advantageously adjust the size of outwarding winding torque M L.
Opposite with the embodiment of the groove with analogous shape 7 shown in Figure 17, Figure 11 other embodiments with the helical element 1 shown in the mode of horizontal and vertical sectional view in Figure 12 are designs like this: screw thread safty device 60 are not to link together with the matrix 2 usefulness multi-part jet moulding moulding of helical element 1 and with it.Screw thread safty device 60 are pressed in the groove 7.This point to Figure 13 to embodiment shown in Figure 15 also be like this.Yet, as long as adopted the O shape ring that resembles among Fig. 4 or Figure 10 extraly, perhaps assembly parts 11 as shown in Figure 5, perhaps another screw thread safty device 6 as shown in Fig. 1,3 or 4, this kind embodiment also falls within the framework of the present invention.
The screw thread safty device 60 that show as separating component are pressed in the T connected in star 7 of matrix 2, and the bottom land that wherein is positioned at inner radial is that the crossbeam by T forms.Thus, the groove width of bottom section 7a is greater than the groove width of the groove inlet 7b that is positioned on the edge.Thus, can realize on the one hand screw thread safty device 60 are clamped in groove inlet 7b well, that is to say and cooperate the mode of (Kraftschluessig) to link together with matrix 2 with power screw thread safty device 60, on the other hand, screw thread safty device 60 are not the space of filling up fully among the bottom section 7a of groove 7, when screw thread safty device 60 resiliently deformables, exist spare space can supply to utilize in the space of described bottom section 7a like this.As the hetero-polymer material that is used for matrix 2 and screw thread safty device 60, preferably be used in the present embodiment, adopt polyamide (PA), particularly adopt polyamide (PA, (the fasergef ü llt) of GFK-fiberfill fibers) be used for matrix 2, and adopt thermoplastic elastomer (TPE) (TPE) to be used for screw thread safty device 60.Just as hereinafter address as Figure 13 to Figure 18 and helical element embodiment shown in Figure 24, adopt the hollow posts bodily form embodiment of the helical element 1 of this kind material pairing to have independently creative meaning equally.A kind of like this helical element 1 especially can be used as locking nut, be used for valve, as locking nut and ABAP Adapter (Adapter), in this, with the embodiment shown in all substantially just the samely, can realize that also so-called kinology changes, in other words, helical element 1 also may be implemented as the mode with the internal thread that is threaded safty device 6,60, has externally threaded mode and be implemented as with member 8 that this helical element links together.
In the embodiment shown in Figure 13 to Figure 15, the screw thread safty device 60 for being pressed in the groove 7 have designed different forms of implementation respectively.In the embodiment show in figure 13, screw thread safty device 60 comprise two insurance parts 60a, 60b.Insurance parts 60a, 60b make with different materials respectively, and Young's modulus, hardness and the characteristic of rubbing that therefore can double thread safty device 60 exert an influence, and by these mechanical properties to safety effect, promptly the torque M L that outwards winding of helical element 1 exerts an influence.Material as insurance parts 60a, 60b also can be selected to adopt metal to replace plastics.
In the embodiment that Figure 14 and Figure 15 illustrate separately, with different in whole other embodiments, the Y-Y axle that is used for the groove 7 of screw thread safty device 60 is not radially, but extends through matrix 2 according to the form of secant (Sekante).Can be achieved as follows purpose by this asymmetric form: on helical element 1, must according to its whether along or apply different torques against screw-in direction ER rotation.For example, helical element 1 shown in Figure 14 to outward winding torque M L bigger than the torque that is used to screw in helical element 1, because the outer diameter D 1 of the screw thread 3 before being positioned at groove 7 on the screw-in direction ER is greater than the outer diameter D 2 of the screw thread 3 be positioned at groove 7 on screw-in direction ER after.Here, the external frame K of screw thread safty device 60 with align than minor diameter D2, and be positioned within the circumcircle that has than major diameter D1.In the embodiment of the helical element shown in Figure 15 1, before being positioned at groove 7 on the screw-in direction ER and the outer diameter D equal and opposite in direction of screw thread 3 afterwards.The external frame K of screw thread safty device 60 is radially outstanding in the mode that exceeds this external diameter.Therefore, compare with the embodiment shown in Figure 14, the torque M L that outwards winding in this embodiment is bigger with the screw-in torque.
The helical element 1 that relates among the embodiment shown in Figure 16 to 18, its matrix 2 and screw thread safty device 6 are with moulding in the multi-part injection molding technology and are connected to each other together.Also adopt different materials to be used for screw thread safty device 6 respectively here.Two screw thread safty device 6 shown in Figure 16 are by different made.6 each free two insurance parts 6a, 6b that make with different materials constitute at the screw thread safty device shown in Figure 17 and Figure 18.The polymer that can preferably have different hardness numbers, Young's modulus and the coefficient that rubs here, therefore, with the similar ground of embodiment shown in Figure 13, can be advantageously in the way you want to safety effect, just the torque M L that outwards winding of helical element 1 exerts an influence.The same with the embodiment shown in Figure 13, the groove 7 that is used for the screw thread safty device is configured to T shape on cross section, yet, these cross sections respectively by separately screw thread safty device 6 form fit fill up, like this, screw thread safty device 6 also have the cross section of T shape.
Among the embodiment of helical element 1 shown in Figure 17, less insurance parts 6b is embedded among another bigger insurance parts 6a and with these insurance parts 6a and forms common surface.In the embodiment shown in Figure 18, the first insurance parts 6a is positioned on another second insurance parts 6b, and has the surface that the first insurance parts 6a forms screw thread safty device 6 only.
The embodiment of the helical element 1 shown in Figure 19 is a screw, that is to say it is solid body (Vollkoerper), and by this screw, two other member 8a, 8b are joined together.Have only the member 8b shown in Figure 19 below to have screw thread 9 here.Screw thread safty device 6 make and produce asymmetric structure in the screw-in process, the effect of this dissymmetrical structure is, the X-X axle that makes helical element 1 produces with respect to the central shaft X1-X1 among the opening 8c that is extended through by helical element 1 of the member 8a shown in Figure 19 top and departs from.This point has also obtained explanation apart from p between the wall (not identifying) of the opening 8c of the screw thread 3 by helical element 1 and upper component 8a.
In the embodiment shown in Figure 20 to Figure 23, screw thread safty device 6 are formed by the annulus (Ringsektor) that circumferentially extends in the zone of the screw thread 3 of helical element 1.By this can along or the annulus implemented against screw thread 3 directions, can be to the torque M L increased clamping force of outwarding winding of impelling helical element 1 by the girth of helical element 1 and highly fine and adjust targetedly.Here, as shown in Figure 20, also can be preferably only fully or partly by the elastic material of screw thread safty device 6, for example elastomer, especially thermoplastic elastomer (TPE) form with a pitch of the screw thread 3 of helical element 1.Within the scope of the invention, elastic material typically refers to its elasticity material bigger than the elasticity of the material of matrix 2.
The cross section of described annulus especially resembles the object that rectangular cross-section shown in Figure 21 and helical element 1 are screwed in
The shape of 8 screw thread 9 is not adaptive, like this, because the form variations (as shown in figure 22) when screwing in, can produce certain compressed (verpresst) volume part of V, thereby form a kind of connection, as shown in figure 23, in this connection, screw thread safty device 6 are sandwiched between two flank of thread 9a of screw thread 9 of described object 8 at least.By the compressed volume part of V of screw thread safty device 6, screw thread 3,9 mating face is each other increased, and the normal force that affacts on the profile side is under control.Rubbing is increased, and thereby has increased the torque M L that outwards winding.Annulus also can be implemented to non-circular member as required, thereby is out of shape targetedly when tightening the screw.
Figure 24 shows another embodiment of the present invention, and the screw thread safty device 16 among this embodiment are identical with screw thread safty device among the embodiment of Fig. 6 and helical element 1 shown in Figure 7 basically.Here relate to a kind of with dynamic function screw thread safty device 16 structure, that can carry out the transition to state of activation from unactivated state.Figure 24 illustrates its state of activation.As among the embodiment shown in Figure 20 to Figure 23, screw thread safty device 16 preferably can be the annulus that can be arranged in the screw thread 3.The activation of safty device 16 is to realize by the pin in the axially open 22 that extend into helical element 1 20.When pin 20 injects in the opening 22 (direction of insertion Q), screw thread safty device 16 are pressed to by radially outward the bottom section generation effect of the mode double thread safty device 16 of its active position in the plane of inclination 24 on its top.Therefore, screw thread safty device 16 must be movable with respect to helical element 1, and cannot be in the groove 7 of bottom lock--in the groove 7 of non-at least complete closed, on the contrary, groove 7 must have the breach 26 of the axially open 22 in helical element 1, so that pin 20 can be worked in the bottom section of screw thread safty device 16.In addition, the height H E of screw thread safty device 16 must be designed to make it in fact to be in unactivated state dimensionally when pin 20 does not exist, and is in state of activation when pin 20 exists.Be to guarantee the state of activation of screw thread safty device 16, pin 20 can for example resemble by being constructed to be permeable to be locked in the retainer in the axially open 22 shown in stop bump 20a, 20b and the slit 20c.When designing such screw thread safty device 16, preferably can at first helical element 1 and another member 8 be tightened, activate screw thread safty device 16 then.
Equally can be in Figure 25 and Figure 26 according to the present invention according to the manufacturing of multi-part injection molding technology with another embodiment shown in the longitudinal section form according to helical element 1 of the present invention.This helical element 1 is the link that is used for the connectors of pressure medium system, and described connectors comprises two links, just female part 30 and unshowned inserting member, and described female part 30 is formed by helical element 1 according to the present invention in this example.Inserting member can be inserted in the admittance opening 5 of female part 30 along direction of insertion S to insert a mode along circumferential sealing, and by 40 lockings of the holder in the space 39 that can put in and be seated in female part 30.
Figure 25 shows the female part 30 and holder 40 before the assembling respectively, and Figure 26 shows female part 30 and holder 40 under assembling finishes state respectively, and wherein, female part 30 can be screwed in another member 8 by its outside thread 3.Internal thread with outside thread 3 complementations helical element 1 member 8 still identifies with reference character 9.
Inserting member can be locked on the one hand the pre-stop position of sealing fully that part is inserted, non-in female part 30, can be locked on the other hand insert fully, the full stop position of sealing fully airtightly, unclamp preventing.Therefore, in two stop positions, the retainer 42 of holder 40 is bonded on the rear side of the stop rib of inserting member under the situation that forms the stop connection respectively.In pre-stop position, non-tight is set in desirable mode.This state can pass through leakage noise when pressurization
And from the acoustics perceived to, and can not take place completely, unexpected pressure reduces.Be connected and continue when leakage noise occurring to carry out the transition in the full stop position of correct sealing and locking.
Holder 40 is constructed as follows and is arranged in the space 39 of female part 30 in mode that can relative movement: at least in full stop position, at least one retainer 42 can be by promoting holder 40 against direction of insertion S, and carry out the transition to the lock position from non-lock position, can cancel it is connected with stop between the inserting member in this non-lock position, in this lock position, described stop connects by the prevention of form fit ground to be cancelled.Be the inefficacy that form fit ground stops stop to connect, be provided with and the synergistic bolt-lock of retainer 42 portion 44 that described bolt-lock portion 44 radially stretches in the space 39.
Specifically, holder 40 comprises grabbing folder retainer 46 and two retainers 42 in the space 39 that is seated in female part 30, this retainer 42 with mode that diametrically can resiliently deformable be clamped in described grab among the folder retainer 46 and in the axial direction before and after ground arrange, the stop rib of inserting member is lived from the back side engagement by first retainer 42 in pre-stop position, and is lived from the back side engagement by second retainer 42 in full stop position.The folder holder 46 of grabbing that is configured to annular solid has two and especially is the slot-shaped receiving compartment that is used for retainer 42.
Especially the circumferential seal of being made by elastomer 100 is set in the aperture scope of the admittance opening 5 of female part 30, and described circumferential seal 100 is used for sealing to prevent that pollutant, dust, moisture etc. from entering.
For the inserting member in the admittance opening 5 of female part 30 is sealed, in the inner region of the admittance opening 5 of the female part 30 adjacent, the circumferential seal 200 that another is equally especially made with elastomer is set with holder 40.
