Description

螺帽 Nut

本發明係關於一種螺帽，特別是一種可以配合一彈性體使用之螺帽，可用確保該彈性體具彈性的頂撐在該螺帽與被固定物之間，使該螺帽可以將被固定物牢固之固定者。 The invention relates to a nut, in particular to a nut which can be used with an elastic body, can be used to ensure that the elastic body is elastically supported between the nut and the object to be fixed, so that the nut can be fixed. The firm is fixed.

請閱第1圖所示，其係一種習知以螺帽91與螺栓92將一被固定物9固定之實施例，為確保該被固定物9被牢固之固定，該螺帽91與被固定物9之間通常會填置一彈性體93(例如：彈性墊圈)及一平面墊圈94，藉由對螺帽91與螺栓92之旋合，以將被固定物9固定。 Referring to Fig. 1, an embodiment in which a fixed object 9 is fixed by a nut 91 and a bolt 92 is known. To ensure that the fixed object 9 is firmly fixed, the nut 91 is fixed. An elastic body 93 (for example, a spring washer) and a flat washer 94 are usually filled between the objects 9 to fix the fixed object 9 by screwing the nut 91 and the bolt 92.

請閱第2圖所示，當對螺帽91與螺栓92施力旋合當中，由於使用者之習性不同，或因使用者之經驗不同，或因使用者之喜好不同，在旋合該螺帽91與螺栓92時，該施力之大小將造成彈性體93之變形量不同，因此，該被固定物9就會形成未被牢固固定，或旋轉過緊問題。尤其是，當使用者用力過當，導致該彈性體93形成單一厚度之板片無法再變形時，該彈性體93即不再具有彈性，該彈性體93僅等同於一平面墊圈94，使螺帽91與被固定物9之間再也無法形成彈性螺合狀態。 Referring to FIG. 2, when the nut 91 and the bolt 92 are rotatably screwed together, the nut 91 is screwed due to the user's habit, or due to the user's experience, or because the user's preference is different. In the case of the bolt 92, the magnitude of the biasing force causes the amount of deformation of the elastic body 93 to be different. Therefore, the fixed object 9 is formed without being firmly fixed or rotated too tightly. In particular, when the user exerts a force to cause the elastic body 93 to form a single thickness, the elastic sheet 93 is no longer elastic, and the elastic body 93 is only equivalent to a flat washer 94, so that the nut It is no longer possible to form an elastic screwing state between the 91 and the object to be fixed 9.

再者，上述習知以螺帽91與螺栓92將一被固定物9固定之實施例當中，該螺帽91與被固定物9之間同時填置一彈性體93 及一平面墊圈94，如此，該習知固定方式，也將增加一平面墊圈94之設置成本。 Furthermore, in the above-described embodiment in which the nut 91 and the bolt 92 are used to fix a fixed object 9, an elastic body 93 is simultaneously filled between the nut 91 and the fixed object 9. And a flat washer 94, as such, the conventional fixing method will also increase the installation cost of a flat washer 94.

有鑑於此，上述習知固定方式係有必要再予以改良，使一彈性體被設於該螺帽與被固定物之間時，該彈性體仍具有適度之彈性，以確保該彈性體成一定彈性之頂撐在螺帽與被固定物之間者。 In view of the above, it is necessary to further improve the above-mentioned conventional fixing method. When an elastic body is disposed between the nut and the object to be fixed, the elastic body still has moderate elasticity to ensure that the elastic body is formed. The elastic top is supported between the nut and the object to be fixed.

綜上所述，本發明之螺帽1，由於至少在該螺帽1之一表面具有一沈孔13，因此，當選擇適當之彈性體3置入在該沈孔13及與螺栓2作螺合使用時，不管使用者之習性、經驗、喜好如何，只要螺帽1之端面抵接到被固定物4時，對該螺帽1再大之驅動力，也無法使彈性體3變形，如此，該彈性體3仍保持有適當的彈性，以頂撐在螺帽1與被固定物4之間，使該彈性體3可以保持在最佳彈性狀態之效果。再且使用本發明之螺帽1時，也可以省略習知之平面墊圈，可以達到降低成本之功效。 In summary, the nut 1 of the present invention has a counterbore 13 at least on one surface of the nut 1, so that when the appropriate elastic body 3 is selected, the counterbore 13 is placed and the bolt 2 is screwed. When used in combination, regardless of the user's habits, experience, and preferences, as long as the end face of the nut 1 abuts against the object to be fixed 4, the driving force of the nut 1 is further increased, and the elastic body 3 cannot be deformed. The elastic body 3 still maintains proper elasticity to be supported between the nut 1 and the object to be fixed 4, so that the elastic body 3 can maintain the effect of the optimum elastic state. Further, when the nut 1 of the present invention is used, the conventional flat washer can be omitted, and the cost reduction effect can be achieved.

雖然本發明已利用上述較佳實施例揭示，然其並非用以限定本發明，任何熟習此技藝者在不脫離本發明之精神和範圍之內，相對上述實施例進行各種更動與修改仍屬本發明所保護之技術範疇，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。 While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention.
