Description
本發明,是對於被安裝構件將螺絲進行安裝而成的安裝構造。 The present invention is an attachment structure in which a screw is attached to a member to be attached.
對於本體部(被安裝構件),將安裝構件以螺栓來安裝固定,並且螺栓的防鬆是以螺栓本身的構造來進行的技術,本發明申請人開發了下述的專利文獻1所記載的安裝構造。 In the body portion (the member to be mounted), the mounting member is attached and fixed by bolts, and the bolt is prevented from being loosened by the structure of the bolt itself. The applicant of the present invention has developed the installation described in Patent Document 1 below. structure.
專利文獻1:日本特開2004-324820號公報 Patent Document 1: Japanese Laid-Open Patent Publication No. 2004-324820
在此以往的安裝構造中,在螺栓的螺栓頭的底面設有:具有錐狀外周面的圓錐梯形凸部,並同時設有偏心錐凸部,並且在螺栓承接部朝往螺栓頭的對向面,設有使前述凸部嵌合的凹部,這些凸部以及凹部的直徑比螺絲軸更大,並且凹部的內周面設成和螺絲軸為同心狀;凸 部的外周面對於螺絲軸有微少量的偏心。 In the conventional mounting structure, a conical trapezoidal convex portion having a tapered outer peripheral surface is provided on the bottom surface of the bolt head of the bolt, and an eccentric taper convex portion is provided at the same time, and the bolt receiving portion faces the bolt head. The surface is provided with a concave portion for fitting the convex portion, the convex portion and the concave portion have a larger diameter than the screw shaft, and the inner circumferential surface of the concave portion is formed concentrically with the screw shaft; The outer peripheral surface of the portion has a slight amount of eccentricity to the screw shaft.
此外,凸部的偏心量,製作成和螺栓接受部的插通孔(10)與螺絲軸相互嵌合的間隙大致相等;或是比插通孔與螺絲軸相互嵌合的間隙更大,藉此,插通孔的內周面和螺絲軸的外周面在圓周方向一部分上被壓接,並使凸部的外周面和凹部的內周面在其相反側被壓接,而產生防鬆作用。 Further, the eccentric amount of the convex portion is formed to be substantially equal to the gap in which the insertion hole (10) of the bolt receiving portion and the screw shaft are fitted to each other; or the gap between the insertion hole and the screw shaft is larger. In this case, the inner circumferential surface of the insertion hole and the outer circumferential surface of the screw shaft are crimped in a part of the circumferential direction, and the outer circumferential surface of the convex portion and the inner circumferential surface of the concave portion are crimped on the opposite side thereof to cause a loosening effect. .
上述先前技術中,由於螺絲軸和被安裝構件的螺絲孔不是在螺鎖狀態下呈偏心的樣式,因此要以能夠得到充分的防鬆作用的方式設計,製造面上品質管理的進行相當困難。亦即,本發明申請者所製造販售的HARDLOCK(日本註冊商標)螺帽,可藉由偏心嵌合使螺絲螺合部分偏心而發揮強力的防鬆作用,而上述先前技術中插通孔(10)的內周面是圓筒狀,插通孔和螺絲軸之間在軸向上能夠自由地相對移動,所以錐狀的凸部和凹部在圓周方向一部分上會接觸,並且在其直徑方向相反側在插通孔和螺絲軸接觸的時間點只能夠螺入些許的螺栓,而以該些許的螺入產生斜楔作用來進行防鬆,因此要求相當嚴苛的尺寸管理。 In the above prior art, since the screw shaft and the screw hole of the member to be mounted are not eccentric in the screw-lock state, it is difficult to carry out the quality management on the manufacturing surface in such a manner that a sufficient anti-loosening effect can be obtained. In other words, the HARDLOCK (Japanese registered trademark) nut which is sold by the applicant of the present invention can exert a strong anti-loosening action by eccentric fitting to eccentrically screw the screw portion, and the above-mentioned prior art insertion hole ( The inner peripheral surface of 10) is cylindrical, and the insertion hole and the screw shaft are freely movable relative to each other in the axial direction, so that the tapered convex portion and the concave portion are in contact with each other in the circumferential direction, and are opposite in diameter. The side can only be screwed into a small number of bolts at the point of contact of the insertion hole and the screw shaft, and the slight screwing action causes the wedge to act to prevent loosening, thus requiring quite strict dimensional management.
因此,本發明之目的在於,在具有螺栓或是小螺釘等的螺絲,而不使用螺帽的安裝構造中,使其也能 夠得到和HARDLOCK螺帽同等的防鬆作用。 Therefore, an object of the present invention is to enable a screw having a bolt or a small screw or the like without using a nut. It has the same anti-loosening effect as the HARDLOCK nut.
本發明,是為了達成上述目的,而採用了以下的技術方案。 The present invention has been made in order to achieve the above object.
亦即,本發明的安裝構造,其特徵為,具有螺絲和被該螺絲所螺鎖的被安裝構件,前述螺絲,以在軸向上連續設置的方式,具備:螺絲頭、以及外周面形成有公螺紋的螺絲軸,前述被安裝構件,具備:被前述螺絲軸所螺鎖的螺絲孔、以及被前述螺絲頭所內嵌的嵌入孔,前述螺絲頭的外周面以及嵌入孔的內周面,是隨著從前述螺絲軸以及螺絲孔側朝向軸向外方而逐漸變大直徑的錐面; 前述螺絲頭的外周面的軸心是相對於前述螺絲軸的軸心呈偏心、或者該嵌入孔的內周面的軸心是相對於前述螺絲孔的軸心呈偏心,以使前述螺絲頭以遍及全周地接觸前述嵌入孔內的方式完成嵌合時,前述螺絲軸軸心能夠在相對於前述螺絲孔軸心軸心呈偏心的狀態下被螺鎖。 That is, the mounting structure of the present invention is characterized in that it has a screw and a member to be attached which is screwed by the screw, and the screw is provided continuously in the axial direction, and includes a screw head and a peripheral surface formed with a male The threaded screw shaft includes: a screw hole that is screwed by the screw shaft; and an insertion hole that is fitted into the screw head; an outer circumferential surface of the screw head and an inner circumferential surface of the insertion hole; a tapered surface that gradually becomes larger as it goes outward from the screw shaft and the screw hole side toward the axial direction; The axial center of the outer circumferential surface of the screw head is eccentric with respect to the axial center of the screw shaft, or the axial center of the inner circumferential surface of the insertion hole is eccentric with respect to the axial center of the screw hole, so that the screw head is When the fitting is completed so as to be in contact with the insertion hole over the entire circumference, the screw shaft axis can be screwed in a state of being eccentric with respect to the axial center of the screw hole.
如使用本發明的安裝構造,將螺絲逐漸螺入螺絲孔時,由於螺絲頭和嵌入孔呈偏心,螺絲頭的外周面和嵌入孔的內周面會在圓周方向上一部分上接觸。如進一步螺入螺絲,由於在上述接觸部位的徑向相反側螺絲頭和嵌入孔之間會產生間隙,並且螺絲軸的公螺紋和螺絲孔的母螺紋之間會形成些許的空隙,螺絲會一面少量地傾斜一面被螺鎖,在此過程中螺絲軸的公螺紋和螺絲孔的母螺紋 會逐漸地偏心,隨著被螺入,相當大的徑向應力會逐漸被蓄積在螺絲軸上。此後,在螺絲頭完全地嵌合在嵌入孔的狀態中,會在螺絲軸偏心的狀態下被螺鎖在螺絲孔,相當大的斜楔力會作用在螺絲全體上,而發揮強力的防鬆作用。 When the screw is gradually screwed into the screw hole by using the mounting structure of the present invention, since the screw head and the insertion hole are eccentric, the outer circumferential surface of the screw head and the inner circumferential surface of the insertion hole are partially contacted in the circumferential direction. If the screw is further screwed in, a gap will be generated between the screw head and the insertion hole on the opposite side of the contact portion, and a slight gap will be formed between the male screw of the screw shaft and the female screw of the screw hole, and the screw will have a side. Slightly tilted one side is screwed, the male thread of the screw shaft and the female thread of the screw hole in the process It will gradually become eccentric, and as it is screwed in, considerable radial stress will gradually accumulate on the screw shaft. Thereafter, in a state in which the screw head is completely fitted in the insertion hole, the screw shaft is screwed into the screw hole in an eccentric state, and a relatively large wedge force acts on the entire screw to exert a strong anti-loose effect. effect.
上述本發明的安裝構造中,較佳為,該錐面的軸長度,和前述螺絲孔的軸長度相同或是比前述螺絲孔的軸長度更長。藉此,能夠使讓螺絲軸相對於螺絲孔偏心而產生的相當大的力量藉由上述錐面而發揮出來,並且就算錐面的尺寸精度較小也能夠確實地產生防鬆作用。 In the above-described mounting structure of the present invention, it is preferable that the axial length of the tapered surface is the same as or longer than the axial length of the screw hole. Thereby, a considerable force generated by eccentricity of the screw shaft with respect to the screw hole can be exerted by the tapered surface, and even if the dimensional accuracy of the tapered surface is small, the loosening action can be surely produced.
此外,前述偏心量,較佳為,是和前述螺絲軸的公螺紋相對於前述螺絲孔的母螺紋的遊隙量大致相等。 Further, it is preferable that the amount of eccentricity is substantially equal to the amount of play of the male screw of the screw shaft with respect to the female screw of the screw hole.
此外,前述螺絲,進一步具備在前述螺絲頭和前述螺絲軸之間設置成一體的樞軸部,並能夠將旋轉構件以能夠旋轉的方式安裝在該樞軸部。例如,把眼鏡的構架當作上述被安裝構件,把眼鏡的鏡腳當作上述旋轉構件,藉由採用本發明作為眼鏡的鏡腳的安裝構造,能夠低價地提供用以安裝鏡腳之螺絲不會鬆動的眼鏡。 Further, the screw further includes a pivot portion that is integrally provided between the screw head and the screw shaft, and the rotating member is rotatably attached to the pivot portion. For example, the frame of the eyeglass is used as the member to be mounted, and the temple of the eyeglass is used as the rotating member. By using the mounting structure of the temple as the temple of the eyeglasses, the screw for mounting the temple can be provided at low cost. Glasses that won't loosen.
憑藉本發明,在不使用螺帽,僅使用螺絲進行安裝的安裝構造中,也能夠使其得到和HARDLOCK螺帽同等的防鬆作用。 According to the present invention, it is possible to obtain the same anti-loosening action as the HARDLOCK nut in the mounting structure in which the screw is used without using the nut.

Heart O Concentrically, the axis P of the screw head 31 is slightly eccentric with respect to the axis O of the shaft portions 32, 33. The outer diameter of the pivot portion 32 is formed to be substantially equal to or larger than the outer diameter of the screw shaft 33. The screw head 31 is formed in a conical trapezoidal shape whose diameter gradually decreases from the upper end to the side of the screw shaft 33, whereby the outer peripheral surface thereof becomes a tapered surface which gradually increases in diameter from the side of the screw shaft 33 to the outside in the axial direction. The angle of the taper surface is preferably about 5° to 15° with respect to the axis P, and more preferably 9° to 11°. Further, the difference between the upper end radius and the lower end radius of the outer peripheral surface of the screw head 31 is preferably larger than the above-described eccentric amount, whereby as shown in FIG. 2, the screw shaft 33 and the screw hole 14 are concentrically arranged. After the screw 3 is gradually screwed in, the lower end of the screw head 31 will smoothly enter the insertion hole 13. Further, the upper surface of the screw head 31 is provided with a tool engagement portion 34, and the engagement groove for the one-word screwdriver is shown in the illustrated example, but the engagement groove for the Phillips screwdriver may be used. The engaging recess of the hexagonal hand can also be used, or other suitable shapes are also possible.
被安裝構件(構架)1設置有構成為剖面字狀的上下一對的支撐片11、12,在這些支撐片11、12之間***鏡腳2的其中一端部。上側支撐片11中設有被上述螺絲頭31所內嵌的嵌入孔13;該嵌入孔13的內周面,製作成和螺絲頭31的外周面相符合的錐面。下側支撐片12中設有被上述螺絲軸33所螺鎖的螺絲孔14,螺絲孔14和嵌入孔13的軸心製作成呈同心狀。這個形成於螺絲孔14的內周面的母螺紋內徑,和螺絲軸33的公螺紋外徑,在設計尺寸上雖然是一致的,但是在實際製造上設 有些許的遊隙,公螺紋外徑(半徑)比母螺紋內徑(半徑)以些許的遊隙量更為小徑。此遊隙量,和上述偏心量大致相等為佳。 The mounted member (frame) 1 is provided with a profile A pair of upper and lower support pieces 11, 12 of a shape are inserted between the support pieces 11, 12 at one end portion of the temple 2. The upper support piece 11 is provided with an insertion hole 13 that is fitted into the screw head 31. The inner circumferential surface of the insertion hole 13 is formed into a tapered surface that conforms to the outer circumferential surface of the screw head 31. The lower side support piece 12 is provided with a screw hole 14 which is screwed by the screw shaft 33, and the screw hole 14 and the axis of the insertion hole 13 are formed concentrically. The inner diameter of the female thread formed on the inner circumferential surface of the screw hole 14 and the outer diameter of the male thread of the screw shaft 33 are identical in design size, but have a slight clearance in actual manufacturing, and the male thread is externally The diameter (radius) is smaller than the inner diameter (radius) of the female thread by a small amount of play. This amount of play is preferably equal to the above-mentioned eccentricity.
此外,上述錐面的軸長度,較佳為,和螺絲軸33的軸長度同等或是比螺絲軸33的軸長度更長,藉此,能夠憑著錐面彼此的嵌合力將螺絲軸33相對於螺絲孔14偏心的力增大。 Further, the axial length of the tapered surface is preferably equal to or longer than the axial length of the screw shaft 33, whereby the screw shaft 33 can be opposed by the fitting force of the tapered surfaces. The force that is eccentric to the screw hole 14 increases.
鏡腳2的其中一端部的上下方向寬度,和上下支撐片11、12之間的間隙寬度大致相等,此鏡腳2的其中一端部上,設有被上述螺絲軸33所插通的插通孔21,該插通孔21的內徑和螺絲軸33的外徑大致相等。此外,螺絲軸33的軸長度,和上下支撐片11、12之間的間隙寬度大致相等。 The width of the one end portion of the temple 2 is substantially equal to the width of the gap between the upper and lower support pieces 11, 12, and one end portion of the temple 2 is provided with a through hole inserted through the screw shaft 33. The hole 21 has an inner diameter of the insertion hole 21 and an outer diameter of the screw shaft 33 which are substantially equal. Further, the shaft length of the screw shaft 33 is substantially equal to the gap width between the upper and lower support pieces 11, 12.
對上述安裝構造的作用進行說明如下:如圖1所示,鏡腳2的其中一端部***於上下支撐片11、12之間,再將螺絲3的螺絲軸33從嵌入孔13側***插通孔21以及螺絲孔14中,在將螺絲3逐漸螺入時,在一開始會以螺絲軸33和螺絲孔14呈大致同心狀的狀態下逐漸被螺鎖。如再繼續螺入,會如圖2所示,在螺絲頭31的外周面中的偏心側的圓周方向一部分會接觸嵌入孔13的內周面。在此狀態下持續螺入的話,因為憑藉著螺絲軸33和螺絲孔14之間的遊隙,可容許螺絲軸33傾斜些許,螺絲3會一面逐漸微少量地傾斜一面被螺入,如圖3所示,在螺絲頭31的外周面中的偏心側的下端部、和它的在直 徑方向上相反側的上端部,會成為和嵌入孔13的內周面接觸的狀態,而會抑制螺絲軸33更進一步的傾斜。如進一步強制地螺入螺絲3,就會如圖4所示,呈現螺絲頭31的外周面和嵌入孔13的內周面遍及全周地接觸,同時螺絲軸33相對於螺絲孔14呈微少量的偏心之狀態下被螺鎖的狀態。 The function of the above-described mounting structure will be described as follows. As shown in FIG. 1, one end portion of the temple 2 is inserted between the upper and lower support pieces 11, 12, and the screw shaft 33 of the screw 3 is inserted and inserted from the side of the insertion hole 13. In the hole 21 and the screw hole 14, when the screw 3 is gradually screwed in, the screw shaft 33 and the screw hole 14 are gradually concentrically locked at the beginning. When the screwing is continued, as shown in FIG. 2, a part of the circumferential direction of the eccentric side in the outer circumferential surface of the screw head 31 contacts the inner circumferential surface of the insertion hole 13. When the screwing is continued in this state, the screw shaft 33 can be allowed to tilt slightly by the play between the screw shaft 33 and the screw hole 14, and the screw 3 is screwed into the side while being slightly inclined, as shown in FIG. As shown, the lower end portion of the eccentric side in the outer peripheral surface of the screw head 31, and its straight The upper end portion on the opposite side in the radial direction is in a state of being in contact with the inner peripheral surface of the insertion hole 13, and the inclination of the screw shaft 33 is further suppressed. If the screw 3 is forcibly screwed in, as shown in FIG. 4, the outer peripheral surface of the screw head 31 and the inner peripheral surface of the insertion hole 13 are in contact with each other over the entire circumference, and the screw shaft 33 is slightly small with respect to the screw hole 14. The state of being screwed in the state of eccentricity.
在此鎖入狀態之下,如圖4的箭頭所示,在螺絲軸部上,徑向的反作用力將會遍及全長地起作用,對於螺絲頭31在其偏心方向的下端部和其相反側的上端部會產生相當大的反作用力,藉由這些反作用力來產生絕大的摩擦抵抗力,而確實地發揮防鬆作用。 In this locked state, as shown by the arrow in Fig. 4, on the screw shaft portion, the radial reaction force will act over the entire length, for the lower end portion of the screw head 31 in the eccentric direction and the opposite side thereof The upper end portion generates a considerable reaction force, and by these reaction forces, a large frictional resistance is generated, and the anti-loosening effect is surely exerted.
本發明並不限定於上述實施形態,而能夠適當地設計變更。例如,也可以將螺絲頭製作成和螺絲軸成為同心狀,並使嵌入孔13相對於螺絲孔呈偏心。並且,上述被安裝構件(構架)1,如圖5所示,可具備:設有在軸向上相對向的2個安裝孔6、7的本體部、設有上述嵌入孔13的第1軸環4、以及設有上述螺絲孔14的第2軸環5,第1軸環4可安裝在其中一方的安裝孔6內,第2軸環5可安裝在另一方的安裝孔7內。2個安裝孔6、7的內面可製作成圓筒面,就算它們的內徑互不相同也可以,如是相同直徑,可利用車床或鑽頭等切削工具將2個安裝孔6、7進行加工。各軸環4、5的軸向外端部設有凸緣。此外,安裝孔6、7的內面,是隨著直至軸向外方逐漸變成大直徑的錐面也可以,此情況下不具有上述突緣也 沒關係。各軸環4、5,是相對於本體部無法旋轉也可以,但圖示例子是以可圍繞軸芯旋轉自如的方式安裝在本體部。如依據圖5所示的實施形態,能夠使軸力作用在螺絲軸上,可期待進一步的防鬆效果,同時也可以應用在複數構件的鎖入固定之上。另外,對被安裝構件1的本體部施以單純的孔加工即可,需要高加工精度的螺絲孔14或是嵌入孔13的錐面可形成在作為較小構件之軸環4、5中。 The present invention is not limited to the above embodiment, and can be appropriately designed and changed. For example, the screw head may be formed concentrically with the screw shaft, and the insertion hole 13 may be eccentric with respect to the screw hole. Further, as shown in FIG. 5, the attached member (frame) 1 may include a main body portion provided with two attachment holes 6 and 7 facing each other in the axial direction, and a first collar provided with the insertion hole 13 4. The second collar 5 having the screw hole 14 is provided. The first collar 4 can be mounted in one of the mounting holes 6, and the second collar 5 can be mounted in the other mounting hole 7. The inner faces of the two mounting holes 6, 7 can be formed into a cylindrical surface, even if the inner diameters thereof are different from each other. If the same diameter is used, the two mounting holes 6, 7 can be processed by a cutting tool such as a lathe or a drill. . The axially outer end portions of the respective collars 4, 5 are provided with flanges. Further, the inner faces of the mounting holes 6, 7 may be tapered surfaces which gradually become large diameters as they extend outward in the axial direction, and in this case, the above-mentioned flanges are not provided. It's ok. Each of the collars 4 and 5 may be rotatable with respect to the main body portion, but the illustrated example is attached to the main body portion so as to be rotatable around the shaft core. According to the embodiment shown in Fig. 5, the axial force can be applied to the screw shaft, and a further anti-loosening effect can be expected, and it can also be applied to the locking and fixing of a plurality of members. Further, the main body of the member to be attached 1 may be subjected to simple hole processing, and the screw hole 14 or the tapered surface of the insertion hole 13 which requires high machining accuracy may be formed in the collars 4 and 5 which are smaller members.
