Description

手工具套合部結構 Hand tool sleeve structure

本發明係與一手工具套合部結構有關，尤指一種手工具套合部結構中，該本體之外徑及該套合部不會磨損該螺合件之角端，該套合部在外徑及不會磨損之間具有更佳之平衡結構，該第一圓之圓心與該第二六邊形之角端位置相同，該套合部可套合該星形螺合件以驅動之，而具擴充性。 The present invention is related to a hand tool sleeve structure, in particular to a hand tool sleeve structure, in which the outer diameter of the body and the sleeve will not wear the corner of the screw part, the sleeve has a better balance structure between the outer diameter and not wearing, the center of the first circle and the corner of the second hexagon are at the same position, the sleeve can be sleeved with the star-shaped screw to drive it, and is expandable.

按吾人先前所知，習用之手工具套合部結構，如美國專利案號：US2007/0125204A1，台灣專利案申請號：093219645，證書號：M270886，專利名稱：防螺帽頭受損之套筒。 As we know before, the commonly used hand tool sleeve structure, such as US patent case number: US2007/0125204A1, Taiwan patent application number: 093219645, certificate number: M270886, patent name: socket to prevent nut head from being damaged.

但此習用手工具套合部結構之缺失係在於： However, the defects of the joint structure of the hand tool used in this practice are:

1、請輔以公報之第五圖及第七圖所示，當該套筒20與該螺帽頭40相套合旋動時，該六個卡抵斜凸24係卡掣於該螺帽頭40六個邊面之略中央處而帶動該螺帽頭40轉動，該卡抵斜凸24係很凸出於該套合孔22內，該套合孔22之該閃避槽23與該螺帽頭40之角端間即有很大之間隔，該套合孔22在旋動時應很難磨損至該螺帽頭40之角端，結構上該卡抵斜凸24凸出越多磨損該螺帽頭40之角端之機率係更低，但若該卡抵斜凸24之凸出狀係更為凸出，該套筒20為維持其旋動扭力，該套筒20即需有一定壁厚，該卡抵斜凸 24呈凸出狀時即會使該套筒20之外徑增加，越凸出結構上該套筒20之外徑更大。 1. Please refer to the fifth and seventh figures of the Gazette. When the sleeve 20 and the nut head 40 are fitted and rotated, the six oblique projections 24 are locked in the center of the six sides of the nut head 40 to drive the nut head 40 to rotate. The oblique projections 24 are protruding from the fitting hole 22. There is a large gap between the avoidance groove 23 of the fitting hole 22 and the corner end of the nut head 40. The fitting hole 22 is rotated. It should be difficult to wear the corner of the nut head 40. The more the oblique protrusion 24 protrudes, the lower the probability of wearing the corner of the nut head 40. However, if the oblique protrusion 24 is more protruding, the sleeve 20 needs to have a certain wall thickness to maintain its rotational torque. When the oblique protrusion 24 is protruding, the outer diameter of the sleeve 20 will increase. The more protruding the outer diameter of the sleeve 20 is, the larger the outer diameter of the sleeve 20 is.

2、該卡抵斜凸24係呈尖角狀，該卡抵斜凸24之旋動扭力係較為不足，且該套筒20旋動該螺帽頭40一段時間後係可能會使該卡抵斜凸24磨成圓角狀。 2. The oblique projection 24 of the card is in a sharp angle shape, and the rotational torque of the oblique projection 24 of the card is relatively insufficient. Moreover, after the sleeve 20 rotates the nut head 40 for a period of time, the oblique projection 24 of the card may be worn into a rounded shape.

3、該套筒20在旋動該螺帽頭40時均係為該卡抵斜凸24與該螺帽頭40之間相接觸，該卡抵斜凸24呈尖角狀，該卡抵斜凸24會造成該螺帽頭40之咬痕。 3. When the sleeve 20 rotates the nut head 40, the oblique projection 24 contacts the nut head 40. The oblique projection 24 is sharp and will cause bite marks on the nut head 40.

另外如吾人先前已取得專屬授權之手工具套合部結構，台灣專利案申請號：106214943，證書號：M555783，專利名稱：手工具套合部結構：一第一本體，該第一本體係設有第一套合部，該第一套合部係包括有六個驅動部及六個容置部，該驅動部及該容置部係呈間隔環狀排列狀；該第一本體之該驅動部係呈凸弧面狀，每一驅動部係包括二第一弧面及一第二弧面，該第二弧面係設於該驅動部之中央處，該第二弧面係設於該第一弧面間，該第二弧面係更凸出於該第一弧面，使該第一弧面係受該第二弧面所間隔而成二個狀，該第一弧面之半徑係為第一半徑，該第二弧面之半徑係為第二半徑，該第一半徑係大於該第二半徑，該第一弧面相切一水平線與該第二弧面亦相切一水平線而係具有第一距離，該第一距離係小於0.5mm；該容置部係呈凹弧面狀，每一容置部係設於每二個第一弧面間，該容置部內係形成有一第一圓，該第一圓係與該第一弧面係呈相切狀，該第一圓與該第一弧面之間之關係即等同於該大凸弧面與該小凹弧面間之關係，該容置部與該第一弧面係呈不相切狀，該容置部之半徑係大於該第一 圓之半徑；該第一套合部之軸心處係設有第一圓心，該第一圓心係構成第二圓，該第二圓之外周面係形成一第一六邊形，每一第二弧面係與該第二圓及該第一六邊形之邊面均呈相切狀，該第一圓心係設有第一垂直線，該第二弧面之最凸出處係位於該第一垂直線上，該第一弧面及該第二弧面之圓心亦皆位於該第一垂直線上。 In addition, we have previously obtained exclusive authorization for the hand tool sleeve structure, Taiwan patent application number: 106214943, certificate number: M555783, patent name: Hand tool sleeve structure: a first body, the first body is provided with a first sleeve, the first sleeve includes six driving parts and six receiving parts, the driving parts and the receiving parts are arranged in a spaced ring shape; the driving part of the first body is in a convex arc shape, each The driving part includes two first arc surfaces and a second arc surface, the second arc surface is arranged at the center of the driving part, the second arc surface is arranged between the first arc surfaces, the second arc surface is more protruding than the first arc surface, so that the first arc surface is separated by the second arc surface to form two shapes, the radius of the first arc surface is the first radius, the radius of the second arc surface is the second radius, the first radius is larger than the second radius, and the first arc surface is tangent to a horizontal line and the second arc surface The first arc surface is tangent to a horizontal line and has a first distance, and the first distance is less than 0.5 mm; the accommodation portion is in a concave arc shape, each accommodation portion is arranged between each two first arc surfaces, and a first circle is formed in the accommodation portion, and the first circle is tangent to the first arc surface, and the relationship between the first circle and the first arc surface is equivalent to the relationship between the large convex arc surface and the small concave arc surface, and the accommodation portion is not tangent to the first arc surface, and the radius of the accommodation portion is The first circle is larger than the radius of the first circle; the first center of the first sleeve portion is provided at the axis center, the first center of the first circle forms a second circle, the outer circumference of the second circle forms a first hexagon, each second arc surface is tangent to the second circle and the side surface of the first hexagon, the first center of the first circle is provided with a first vertical line, the most protruding part of the second arc surface is located on the first vertical line, and the centers of the first arc surface and the second arc surface are also located on the first vertical line.

但此專利案之缺失係在於：請輔以公報之第五圖所示，該第一套合部11係僅能套合六角形之螺合件20以配合旋動，其它如該第一套合部11與星形螺合件之間係規格不合而無法相套合驅動，該第一套合部11之舊有規格結構之功能性及擴充性係稍嫌不足。 However, the defect of this patent case is that: as shown in the fifth figure of the publication, the first sleeve part 11 can only be sleeved with the hexagonal screw part 20 for rotation. Other parts such as the first sleeve part 11 and the star-shaped screw part are not in accordance with the specifications and cannot be sleeved and driven. The functionality and expandability of the old specification structure of the first sleeve part 11 are slightly insufficient.

有鑑於上述習用專利案之手工具套合部結構之缺失，本發明人藉多年製造經驗，終於有一能解決習用弊端之手工具套合部結構之產品問世。 In view of the defects of the hand tool sleeve joint structure in the above-mentioned conventional patent, the inventor, with many years of manufacturing experience, finally came up with a product of the hand tool sleeve joint structure that can solve the conventional disadvantages.

習用手工具套合部結構中，該卡抵斜凸之凸出狀係更為凸出，該套筒為維持其旋動扭力，該套筒即需有一定壁厚，該卡抵斜凸會造成該螺帽頭之咬痕。本發明手工具套合部結構中，該本體之外徑及該套合部不會磨損該螺合件之角端，該套合部在外徑及不會磨損之間係具有更佳之平衡結構，且該第一圓之圓心與該第二六邊形之角端位置相同，該套合部可套合該星形螺合件以驅動之，該套合部係具擴充性。 In the conventional hand tool fitting structure, the protrusion of the oblique projection is more prominent. In order to maintain the rotational torque of the sleeve, the sleeve needs to have a certain wall thickness. The oblique projection of the oblique projection will cause bite marks on the nut head. In the hand tool fitting structure of the present invention, the outer diameter of the body and the fitting part will not wear the corner end of the screw part. The fitting part has a better balance structure between the outer diameter and no wear. The center of the first circle is at the same position as the corner end of the second hexagon.

The outer diameter of the body 10 is only slightly increased by the second arc surface 122. The outer diameter of the body 10 and the fitting portion 11 will not wear the corner end of the screw-on component 20. The fitting portion 11 has a better balance structure between the outer diameter and no wear. The center of the first circle 131 is at the same position as the corner end 147 of the second hexagon 146. The fitting portion 11 can fit the star-shaped screw-on component 30 to drive it. The fitting portion 11 is expandable.

6、該第二弧面122係為弧面狀，於旋動時係不會造成該螺合件20之咬痕。 6. The second arc surface 122 is an arc surface, and will not cause bite marks on the screw member 20 when rotating.

7、請再輔以圖5所示，當六邊形之該螺合件20係已磨耗呈略圓角時，該本體10係逆時針旋動該螺合件20，每一該驅動部12之該第二弧面122之最凸出處，亦可靠抵於該螺合件20之每一邊面上，以達到拆解該螺合件20之功效。 7. Please refer to Figure 5 again. When the hexagonal screw part 20 has been worn and has a slightly rounded corner, the main body 10 rotates the screw part 20 counterclockwise, and the most protruding part of the second arc surface 122 of each driving part 12 can also be reliably pressed against each side surface of the screw part 20, so as to achieve the effect of disassembling the screw part 20.
