Description
本發明是有關於一種螺絲，特別是指一種螺絲結構。 The present invention relates to a screw, and more particularly to a screw structure.
參閱圖1與圖2，為習知一種螺絲1，該螺絲1具有一以一軸線L為軸心且沿該軸線L延伸的頭部10，及一連接於該頭部10且以該軸線L為軸心並沿該軸線L延伸的桿部11，該桿部11具有一環繞該軸線L的螺紋段111，其中，該頭部10與該桿部11是以共軸線的方式配置，所以當使用者利用一手工具(圖未示)來操作該頭部10以帶動該桿部11轉動時，其轉動力臂即為該軸線L至一施力點之垂直距離，故進行轉動迫緊時的力臂，完全是靠該手工具的長度來提供，該螺絲1本身結構在力臂上並無任何貢獻。 Referring to FIG. 1 and FIG. 2, there is a conventional screw 1 having a head 10 extending along an axis L and extending along the axis L, and a head connected to the head 10 and having the axis L a shank 11 extending along the axis L, the shank 11 having a threaded section 111 surrounding the axis L, wherein the head 10 and the shank 11 are coaxially arranged, so When the user uses a hand tool (not shown) to operate the head 10 to drive the rod portion 11 to rotate, the rotational force arm is the vertical distance from the axis L to a force application point, so that when the rotation is tight The arm is completely provided by the length of the hand tool, and the structure of the screw 1 itself does not contribute to the arm.
另一方面，在工件的裝配上，該螺絲1是用來將一具有一穿孔301的第一工件300與一具有一螺孔401的第二工件400二者進行固定，由於該螺孔401的一母螺紋402與該螺絲1的該螺紋段111尺寸配合上必定會存在公差，當使用者旋轉該螺絲1而進行迫緊時，在該螺紋段 111之未受力一側112與該母螺紋402之間勢必會產生一背隙500。然而，該等背隙500內因為會夾雜著空氣，所以，在長時間使用之下，會漸漸導致該螺絲1的該螺紋段111或該螺孔401的該母螺紋402受侵蝕，若同時再有遭到外力或振動之影響時，而容易導致該螺絲1鬆脫情況發生。針對上述缺點，雖然已有人利用接固劑來進行改善，但是，如此一來，勢必要再多增加該接固劑的花費成本，而且在組裝上也多了一道工序，故仍有待改善之空間。 On the other hand, in the assembly of the workpiece, the screw 1 is used to fix a first workpiece 300 having a through hole 301 and a second workpiece 400 having a screw hole 401, due to the screw hole 401 The size of a female thread 402 in the size of the threaded section 111 of the screw 1 must have a tolerance. When the user rotates the screw 1 to perform the tightening, the thread section A back gap 500 is bound to be created between the unstressed side 112 of the 111 and the female thread 402. However, because the air is trapped in the back gap 500, the threaded section 111 of the screw 1 or the female thread 402 of the screw hole 401 may be corroded under long-term use, if at the same time When it is affected by external force or vibration, it is easy to cause the screw 1 to loosen. In view of the above shortcomings, although the curing agent has been used for improvement, it is necessary to increase the cost of the cementing agent, and there is an additional process in the assembly, so there is still room for improvement. .
因此，本發明之目的，即在提供一種可以具有良好鎖固與防鬆脫效果且轉動力臂較大的螺絲結構。 Accordingly, it is an object of the present invention to provide a screw structure which can have a good locking and anti-loose effect and a large rotating arm.
於是本發明螺絲結構，包含一頭部，及一桿部。 Thus, the screw structure of the present invention comprises a head and a stem.
該頭部以一第一軸線為軸心且沿該第一軸線延伸，該桿部連接成型於該頭部底側且以一與該第一軸線相間隔的第二軸線為軸心並沿該第二軸線延伸。 The head is centered on a first axis and extends along the first axis, the rod portion is formed on the bottom side of the head and is centered along a second axis spaced from the first axis and along the axis The second axis extends.
本發明之功效在於：藉由該頭部與該桿部二者呈偏心而非共軸線的設計，讓使用者在轉動時可以有較大的轉動力臂，如此一來，施力上能夠較為省力，進而提升鎖固與防鬆脫上的效果。 The utility model has the advantages that the design of the head and the rod portion is eccentric rather than coaxial, so that the user can have a large rotating arm when rotating, so that the force can be relatively high. It saves effort and improves the effect of locking and anti-loose.

在本發明被詳細描述之前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。 Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.
參閱圖3、圖4，及圖5，本發明螺絲結構之第一較佳實施例，適合螺鎖於一具有一母螺紋202的螺孔201，該螺絲結構包含一頭部2，及一桿部3。而該頭部2與該桿部3為金屬材質一體成型而成。 Referring to FIG. 3, FIG. 4, and FIG. 5, a first preferred embodiment of the screw structure of the present invention is adapted to be screwed to a screw hole 201 having a female thread 202. The screw structure includes a head 2 and a rod. Department 3. The head portion 2 and the rod portion 3 are integrally formed of a metal material.
該頭部2以該第一軸線L1為軸心且沿該第一軸 線L1延伸，用以供手工具操作使用，而在本第一較佳實施例中，該頭部2具有一由頂面中間位置往下凹設且供內六角扳手(圖未示)插置使用的扳手凹槽21。 The head 2 is centered on the first axis L1 and along the first axis The line L1 extends for use by the hand tool. In the first preferred embodiment, the head 2 has a recessed portion from the top intermediate position and is inserted into an Allen key (not shown). Use the wrench groove 21.
該桿部3連接成型於該頭部2底側，該桿部3以一與該第一軸線L1相間隔的第二軸線L2為軸心且沿該第二軸線L2並朝遠離頭部2方向逐漸縮束延伸。該桿部3包括一環繞該第二軸線L2的一第一螺紋段31，及一環繞該第二軸線L2且介於該第一螺紋段31與該頭部2之間的第二螺紋段32。其中，在本第一較佳實施例中，該桿部3連接於該頭部2處之直徑為一第一直徑d1，該桿部3中段位置處之直徑為一第二直徑d2，該桿部3尾端之直徑為一第三直徑d3，而且滿足該第一直徑d1>該第二直徑d2>該第三直徑d3之關係，讓該桿部3具有微量錐度外形，並且該第二螺紋段32的長度等於該桿部3長度的一半。當然，在其它實際製造上，該第二螺紋段32的長度也可以設計成大於該桿部3長度的一半，但仍不以此為限制。 The rod portion 3 is connected and formed on the bottom side of the head portion 2, and the rod portion 3 is centered on a second axis L2 spaced apart from the first axis L1 and along the second axis L2 and away from the head portion 2 Gradually shrinking and extending. The rod portion 3 includes a first thread segment 31 surrounding the second axis L2, and a second thread segment 32 surrounding the second axis L2 and interposed between the first thread segment 31 and the head portion 2. . In the first preferred embodiment, the diameter of the rod portion 3 connected to the head portion 2 is a first diameter d1, and the diameter at the middle portion of the rod portion 3 is a second diameter d2. The diameter of the tail end of the portion 3 is a third diameter d3, and the relationship of the first diameter d1>the second diameter d2>the third diameter d3 is satisfied, so that the rod portion 3 has a slight taper shape, and the second thread The length of the segment 32 is equal to half the length of the stem portion 3. Of course, in other practical manufacturing, the length of the second thread segment 32 can also be designed to be greater than half the length of the rod portion 3, but it is not limited thereto.
該第一螺紋段31具有一背向於該頭部2且與該母螺紋202相間隔的第一背側腹面311，及一面向於該頭部2且貼抵於該母螺紋202的第一壓力側腹面312。其中，該第一螺紋段31的結構是同等於習知技術裡所述的螺紋段111(見圖1)，是為一般市面上所習知的螺紋形式。 The first thread segment 31 has a first back side flank 311 facing away from the head 2 and spaced apart from the female thread 202, and a first surface facing the head 2 and abutting against the female thread 202 Pressure side ventral surface 312. Wherein, the structure of the first thread segment 31 is equivalent to the thread segment 111 (see Fig. 1) described in the prior art, and is a thread form conventionally known in the market.
該第二螺紋段32具有一背向於該頭部2且貼抵於該母螺紋202的第二背側腹面321，及一面向於該頭部2且貼抵於該母螺紋202的第二壓力側腹面322。其中，該第 二背側腹面321輪廓外形與該第二壓力側腹面322的輪廓外形不相對稱，由圖4所示，位於假想線上方為該第二螺紋段32的局部放大，位於假想線下方為該第一螺紋段31的局部放大，由圖4中可以清楚的瞭解到，該第一螺紋段31的牙距為P1，該第二螺紋段32的牙距為P2，且該第一螺紋段31與該第一螺紋段32具有相同牙距。其該第二背側腹面321相較於該第一背側腹面311是較為偏離於螺紋中心線M，也就是說，該第二螺紋段32的該第二背側腹面321是較為飽牙的形態，以至於在迫緊該母螺紋202時，該第二背側腹面321能夠和該母螺紋202緊密貼合，此點特徵，是與先前技術裡的該螺紋段111(見圖2)在迫緊於該母螺紋402(見圖2)時的狀態不同。 The second thread segment 32 has a second back side flank 321 facing away from the head 2 and abutting against the female thread 202, and a second surface facing the head 2 and abutting against the female thread 202. Pressure side ventral surface 322. Among them, the first The contour shape of the second back side ventral surface 321 is not symmetrical with the contour shape of the second pressure side ventral surface 322. As shown in FIG. 4, the imaginary line is partially enlarged for the second thread segment 32, and is located below the imaginary line. A partial enlargement of a thread segment 31, as can be clearly seen from FIG. 4, the first thread segment 31 has a pitch P1, the second thread segment 32 has a pitch P2, and the first thread segment 31 is The first thread segment 32 has the same tooth pitch. The second back side ventral surface 321 is more deviated from the thread center line M than the first back side ventral surface 311, that is, the second back side ventral surface 321 of the second threaded section 32 is relatively full. The shape is such that when the female thread 202 is forced, the second back side vent 321 can fit snugly with the female thread 202, which is characterized by the thread segment 111 (see FIG. 2) in the prior art. The state is different when the mother thread 402 (see Fig. 2) is pressed.
在組配使用上，是先將一具有一穿孔101的第一工件100與具有該螺孔201的該第二工件200彼此疊合，並讓該穿孔101與該螺孔201彼此對準後，再將該桿部3穿過該穿孔101，而利用內六角扳手操作該頭部2旋轉，以慢慢地進行迫緊動作，而一開始施力時，因為該第一螺紋段31先接觸到該母螺紋202，其因為尺寸配合上有公差存在之關係，所以，在施力上較為省力，而當該桿部3漸漸被旋轉而往下移動到讓該第二螺紋段32接觸到該母螺紋202時，由於該第二背側腹面321與該第二壓力側腹面322皆是緊貼抵於該母螺紋202二側，所以，在施力上，是需施較大力量，但如此一來，當完全迫緊之後，能夠有效地減少背隙的產生，進而提升鎖固與防鬆脫上的效果。 In the assembled use, the first workpiece 100 having a through hole 101 and the second workpiece 200 having the screw hole 201 are superposed on each other, and the through hole 101 and the screw hole 201 are aligned with each other. Then, the rod portion 3 is passed through the through hole 101, and the head portion 2 is rotated by an internal hexagon wrench to slowly perform the pressing action, and when the force is applied, the first thread segment 31 is first contacted. The female thread 202 is relatively labor-saving in exerting force due to the tolerance of the dimensional fit, and when the rod portion 3 is gradually rotated and moved downward to allow the second thread segment 32 to contact the mother In the case of the thread 202, since the second back side ventral surface 321 and the second pressure side ventral surface 322 are in close contact with the two sides of the female thread 202, a large force is required on the applied force, but such a Come, when it is completely tight, it can effectively reduce the generation of backlash, thereby improving the effect of locking and anti-loose.
另外，由於該頭部2與該桿部3二者分別是以非共軸線的方式設計，亦即偏心的意思，如圖5所示，故該頭部2與該桿部3其軸心之間必定會存在一偏移量X1，而相較於習知技術，由於該頭部10(見圖1)與該桿部11(見圖1)是共軸線故不會存在有該偏移量X1。所以，當使用者利用內六角扳手轉動本發明的該頭部2時，其力臂長度即為一施力源F至該第一軸線L1之間的一垂直距離X2與該偏移量X1之總合，所以相較於習知技術，本發明由於多了該偏移量X1，故增加了力臂，所以，在轉動施力上是能夠更加的省力而利於迫緊。 In addition, since the head portion 2 and the rod portion 3 are respectively designed in a non-coaxial manner, that is, eccentric, as shown in FIG. 5, the head portion 2 and the shaft portion 3 have their axial centers. There must be an offset X1 between them, and compared to the prior art, since the head 10 (see Fig. 1) is coaxial with the stem 11 (see Fig. 1), there is no such offset. X1. Therefore, when the user rotates the head 2 of the present invention with an Allen key, the length of the arm is a combination of a vertical distance X2 between the force source F and the first axis L1 and the offset X1. Therefore, compared with the prior art, the present invention has a larger amount of the offset X1, so that the force arm is added, so that the steering force can be more labor-saving and the tension is facilitated.
再參閱圖3，由於該頭部2是偏心於該桿部3，所以，當迫緊鎖固之後，其該頭部2底側是以非對稱的接觸面與該第一工件100相接觸，如圖3中所示之一大接觸面S1與一小接觸面S2，如此一來，由於該大接觸面S1的面積大，其所產生的磨擦阻力也會較大，故會讓本發明在迫緊之後，更不容易受外力影響而產生鬆脫現象。 Referring to FIG. 3, since the head 2 is eccentric to the rod portion 3, after the locking is tight, the bottom side of the head portion 2 is in contact with the first workpiece 100 by an asymmetric contact surface. As shown in FIG. 3, the large contact surface S1 and the small contact surface S2, as a result of the large contact area S1, the frictional resistance generated by the large contact surface S1 is large, so that the present invention is After being forced, it is less likely to be affected by external forces and become loose.
參閱圖6，為本發明螺絲結構之第二較佳實施例，其內容大致與該第一較佳實施例相同，其不同之處在於：該頭部2的截面外形為六角形，是設計成可供開口扳手(圖未示)操作之態樣。 Referring to FIG. 6, a second preferred embodiment of the screw structure of the present invention is substantially the same as the first preferred embodiment, except that the cross-sectional shape of the head portion 2 is hexagonal and is designed to be It can be operated by an open wrench (not shown).
參閱圖7，為本發明螺絲結構之第三較佳實施例，其內容大致與該第一較佳實施例相同，其不同之處在於：該頭部2的整體外形略成半球形。 Referring to FIG. 7, a third preferred embodiment of the screw structure of the present invention is substantially the same as the first preferred embodiment, except that the overall shape of the head portion 2 is slightly hemispherical.
參閱圖8，為本發明螺絲結構之第四較佳實施例 ，其內容大致與該第一較佳實施例相同，其不同之處在於：該頭部2的整體外形略成半球形，而且該扳手凹槽21是偏心的凹設於該頭部2，如此一來，更增加了力臂，在施力上能夠更為省力，以提升迫緊與防鬆脫效果。 Referring to FIG. 8, a fourth preferred embodiment of the screw structure of the present invention is shown. The content is substantially the same as the first preferred embodiment, except that the overall shape of the head portion 2 is slightly hemispherical, and the wrench recess 21 is eccentrically recessed in the head portion 2, In the first place, the arm is added, and the force can be more labor-saving to enhance the tightening and anti-loose effect.
參閱圖9與圖10，為本發明螺絲結構之第五較佳實施例，其內容大致與該第一較佳實施例相同，其不同之處在於：該扳手凹槽21是偏心的凹設於該頭部2，如此一來，更增加了力臂，在施力上能夠更為省力，以提升迫緊與防鬆脫效果。 Referring to FIG. 9 and FIG. 10, a fifth preferred embodiment of the screw structure of the present invention is substantially the same as the first preferred embodiment, except that the wrench recess 21 is eccentrically recessed in The head 2, in this way, adds a force arm, which can be more labor-saving in applying force to enhance the tightening and anti-loose effect.
參閱圖11與圖12，為本發明螺絲結構之第六較佳實施例，其內容大致與該第一較佳實施例相同，其不同之處在於：該頭部2的截面外形為花瓣形，是設計成可供梅花板手(圖未示)操作之態樣，其施力上較為省力。另外，該扳手凹槽21是偏心的凹設於該頭部2，故當選擇利用內六角板手操作時，也同樣的增加了力臂，在施力上也能夠較為省力，如此二個特點，皆可以用以提升迫緊與防鬆脫效果。 Referring to FIG. 11 and FIG. 12, a sixth preferred embodiment of the screw structure of the present invention is substantially the same as the first preferred embodiment, except that the cross-sectional shape of the head portion 2 is petal-shaped. It is designed to be used by plum blossom wrenches (not shown), and its force is less labor-intensive. In addition, the wrench recess 21 is eccentrically recessed in the head 2, so when the operation is selected by the hexagonal wrench, the same force is added, and the force can be saved in the force application. , can be used to enhance the tight and anti-loose effect.
綜上所述，本發明螺絲結構具有下列優點及功效： In summary, the screw structure of the present invention has the following advantages and effects:
