Description
本發明係有關一種扳手結構改良，尤指一種可增加扳手之扭力值及其強度之扳手結構改良者。 The invention relates to a structural improvement of a wrench, in particular to a wrench structure improvement which can increase the torque value of the wrench and its strength.
按，扳手工具的使用，對於現今的工業發展來說，是一項不可或缺的重要工具，且隨著使用率的廣泛、需求率的增加，扳手結構的功能、種類也有了各種不同的發展、變化，請參閱第一圖所示，其扳手1主要係分別於柄部13二端設置開口扳手11與梅花型固定扳手12(該二端開設的扳手種類可因需求而改變，本發明僅以開口扳手與梅花型固定扳手舉例說明之)，此二種扳手間藉由一柄部13一體成型，該柄部13係呈由開口扳手11的二軸邊延伸至梅花型固定扳手12二軸邊所形成軸線為扁薄狀結構，亦即整個柄部13係呈相等截面積且略呈長條矩形狀的厚薄度設計(如第二~四圖所示)，因此，當使用者於握持、扳動時，往往會產生扳動所產的剪應力需由握持之柄部13近開口扳手11與梅花型固定扳手12及其近中段所承受，而為加強柄部13所能承受的剪應力，通常皆需將該成型之扳手1予以適當加工處理，以增加其硬度，然而柄部13的硬度增加了，相對於開口扳手11與梅花型固定扳手12的硬度及脆度亦增加了，而其靭度則相對減少，使其所能承受的扭力值減少了，而若欲保持開口扳手11與梅花型固定扳手12的靭性，則使柄部13的硬度相對較差，往往於施力較大時造成硬 度較差的柄部13產生變形，進而造成使用者使用上的困擾。 According to the use of wrench tools, it is an indispensable and important tool for today's industrial development. With the wide use rate and increasing demand rate, the functions and types of wrench structures have also developed differently. For the change, please refer to the first figure. The wrench 1 is mainly provided with an open end wrench 11 and a quincunx type fixed wrench 12 at the two ends of the handle portion 13 (the type of the wrench opened at the two ends can be changed according to requirements, and the present invention only The two types of wrenches are integrally formed by a shank 13 extending from the two-axis side of the open-end wrench 11 to the two-axis of the plum-shaped fixed-wound wrench 12, as exemplified by an open-end wrench and a plum-type fixed wrench. The axis formed by the edge is a flat thin structure, that is, the entire shank 13 is of a thickness and a slightly elongated rectangular shape (as shown in the second to fourth figures), so when the user holds When holding and pulling, the shear stress generated by the pulling is often required to be received by the gripped shank 13 near the open wrench 11 and the plum-type fixed wrench 12 and its proximal section, and the shank 13 can withstand Shear stress, usually required to form The wrench 1 is appropriately processed to increase its hardness. However, the hardness of the handle 13 is increased, and the hardness and brittleness of the open wrench 11 and the plum-type fixed wrench 12 are also increased, and the toughness is relatively reduced. The torque value that can be withstood is reduced, and if the toughness of the open end wrench 11 and the quincunx type fixed wrench 12 is to be maintained, the hardness of the shank portion 13 is relatively poor, and the hard force is often caused when the applied force is large. The poorly shank 13 is deformed, which causes trouble for the user.
緣此，本案之發明人基於其從事各種五金工具的設計及製造多年的經驗，尤其於扳手工具的著墨，鑑於現有扳手工具之效果不彰的缺失，期以提供一種柄部結構的變化，而可增加扳手之扭力值及其強度，乃積極加以研究改良，經由多次的試驗及改變，終得本創作的產生。 Therefore, the inventor of this case has based on his years of experience in the design and manufacture of various hardware tools, especially the ink of the wrench tool, in view of the lack of effectiveness of the existing wrench tool, in order to provide a change in the structure of the handle, and The torque value and strength of the wrench can be increased, and it is actively researched and improved. Through many experiments and changes, the creation of this creation is finally achieved.
即，本發明之主要目的乃在於藉由軸邊與菱邊所交錯成型的4條軸線而形成的柄部，產生不同部位的厚薄及斷面形狀變化，而可增加扳手之扭力值及其強度之扳手結構改良者。 That is, the main object of the present invention is to form a shank formed by four axes which are alternately formed by the shaft edge and the rhombic edge, thereby generating thickness and sectional shape changes of different parts, and increasing the torque value and strength of the wrench. The wrench structure is improved.
為達上述之目的，本發明主要係分別於柄部二端設置開口扳手與梅花型固定扳手，且該開口扳手與梅花型固定扳手係呈非同一平面，其中，該柄部係由開口扳手的軸邊延伸至梅花型固定扳手之菱邊而形成一軸線及開口扳手的菱邊延伸至梅花型固定扳手之軸邊而形成一軸線，藉由軸邊與菱邊所交錯成型的4條軸線而形成的柄部，於不同部位產生不同厚薄及斷面形狀的變化，且使受力時應力集中的柄部近中段4條軸線產生厚薄相同的截面積，以承受較大的受力以增強其強度，且使柄部近開口扳手及近梅花型固定扳手之截面積形成一近菱形狀的斷面而非平面狀，以承受較大受力的扳手結構者。 For the purpose of the present invention, the present invention mainly provides an open-end wrench and a plum-type fixed wrench at the two ends of the handle, and the open-end wrench and the plum-type fixed wrench are not in the same plane, wherein the handle is an open-end wrench. The shaft edge extends to the diamond edge of the plum-type fixed wrench to form an axis and the diamond edge of the open-end wrench extends to the axial edge of the plum-type fixed wrench to form an axis, and the four axes are alternately formed by the shaft edge and the rhombic edge. The formed shank produces different thicknesses and cross-sectional shapes at different locations, and the four axial axes of the shank near the middle portion of the shank are concentrated to have the same thickness and the same cross-sectional area to withstand a large force to enhance The strength, and the cross-sectional area of the shank near-opening wrench and the near-plum-type fixed wrench form a nearly diamond-shaped cross section rather than a flat shape to withstand a larger force wrench structure.

And forming an axis 24, 25 and the diamond edge 213, 214 of the open wrench 21 Extending to the shaft edges 223, 224 of the plum-type fixed wrench 22 to form an axis 26, 27, so that the cross-sectional area of the wrench 2 near the open wrench 21 (as shown in the eighth figure), the wrench 2 handle 23 near The cross-sectional area of the middle section (as shown in the ninth figure) and the cross-sectional area of the wrench 2 of the wrench 2 near the plum-shaped fixed wrench 22 (as shown in the tenth figure) are different, and the different parts of the handle 23 are different in thickness and The shape of the cross-section is changed, and the four axes 24, 25, 26, 27 of the near middle portion of the shank portion 23 in the stress at the time of stress are generated to have a cross-sectional area of similar thickness and thickness, so that the stress during stress is not It will focus on one side without causing damage or deformation of the handle 23 to withstand a large force, and the cross-sectional area of the shank 23 near-opening wrench 21 and the near-stitch-type fixed wrench 22 forms a nearly diamond shape. The section is not flat (a section formed by a nearly rhombic shape due to the four axes formed by the interlacing of the shaft and the rhombic). The strength is much longer and the section of the rectangle can withstand a larger force. In this way, not only can the open-end wrench 21 and the quincunx type fixed wrench 22 have greater toughness to withstand large torque, but the shank portion 23 formed by the four axes of the shaft edge and the rhombic edge are alternately formed to enhance Its strength.
上述本發明僅以最佳實施例作舉例說明，對熟悉該項技藝之人員，當可進行各變化實施，惟此變化實施，均應包括在本創作之精神及範疇內。 The present invention has been described by way of example only, and various modifications may be made by those skilled in the art, and the present invention should be included in the spirit and scope of the present invention.
綜上所述，本發明藉由軸邊與菱邊所交錯成型的4條軸線而形成的柄部，產生不同厚薄的變化，且使受力時應力中的柄部近中段產生厚薄相同的截面積，以承受較大的受力以增強其強度，且使柄部近開口扳手及近梅花型固定扳手之截面積形成一近菱形狀的斷面而非平面狀，而可承受較大受力，其不論是結構上的改變，抑或是功效上的增進，皆已毋庸置疑，且本創作於申請前未見於刊物，亦未公開使用，實已符合專利申請要件，爰依法提出專利申請。 In summary, the shank formed by the four axes which are formed by the interdigitation of the shaft edge and the rhombic edge produces different thickness variations, and the same middle section of the shank in the stress during the stress is generated. The area is to withstand a large force to enhance its strength, and the cross-sectional area of the shank near-opening wrench and the near-plum-type fixed wrench forms a nearly diamond-shaped section instead of a flat shape, and can withstand a large force. Whether it is a structural change or an improvement in efficacy, it is beyond doubt, and this creation has not been seen in the publication before the application, nor has it been used publicly. It has already met the requirements for patent application and has filed a patent application according to law.
