本發明係關於一種萬向接頭，特別係關於一種套筒接頭結構。 The present invention relates to a universal joint, and more particularly to a sleeve joint structure.
套筒扳手為現今社會業界經常使用之手工具，其具有拆裝方便、容易施作等優點，惟，當待鎖設件所在之位置周圍之環境狹窄，或者有障礙物阻撓使用者利用套筒扳手施作時，往往造成使用者工作上極大的困擾，為克服前述問題，業界便發展出一種萬向套筒。 The socket wrench is a hand tool commonly used in the social industry today. It has the advantages of convenient disassembly and assembly, easy application, etc., but the environment around the position where the lock is to be locked is narrow, or an obstacle obstructs the user from using the sleeve. When the wrench is applied, it often causes great trouble to the user. To overcome the above problems, the industry has developed a universal sleeve.
如圖1至圖5所示，習知萬向套筒包括，一主動件10、複數耦合件20、一被動件30及複數插銷A，該主動件10之一端具有一施力部11，該主動件之另一端與其中一個該耦合件20可樞轉的結合；該些耦合件20具有依序接鄰之一結合凸部21、一連接部22及平行之二擋部23，該結合凸部21開設一對應孔211，二該擋部23之間形成一容置空間R，二該擋部23於對應之位置分別開設一結合孔231，該連接部22與二該擋部23接鄰之一端具有二擋抵端緣221，二該擋抵端緣221係位於二該擋部23之間，該連接部22之另一端具有一基準端緣222，定義該連接部22之該基準端緣222延伸至該擋抵端緣221之方向為一延伸方向Y，該基準端緣222至該擋抵端緣221之距離為一擋抵俓L1，該基準端緣222至該結合孔231之距離為一樞轉徑L2，該擋抵 俓L1係小於該樞轉徑L2，亦即以該基準端緣222為基準時該擋抵端緣221於該延伸方向Y之高度較結合孔231於該延伸方Y向之高度小，各該耦合件20之結合部21分別依序設置於鄰近之耦合件20之該容置空間R內，藉由該插銷A貫穿該些耦合件20之結合孔231及對應孔211使該些耦合件20以該插銷A為樞軸可樞轉的結合；該被動件30之一端具有一受力部31，該被動件30之另一端與其中一個該耦合件20可樞轉的結合。 As shown in FIG. 1 to FIG. 5, the conventional universal sleeve includes an active member 10, a plurality of coupling members 20, a passive member 30 and a plurality of latches A. One end of the active member 10 has a force applying portion 11, which The other end of the active member is pivotally coupled to one of the coupling members 20; the coupling members 20 have a coupling protrusion 21, a connecting portion 22 and a parallel second blocking portion 23, which are sequentially adjacent to each other. The portion 21 defines a corresponding hole 211, and a receiving space R is formed between the two portions. The second portion of the blocking portion 23 defines a coupling hole 231. The connecting portion 22 is adjacent to the second portion. One end has a second end to the end edge 221, and the second end of the connecting portion 22 is located between the two ends. The other end of the connecting portion 22 has a reference end edge 222 defining the reference end of the connecting portion 22. The direction of the edge 222 extending to the end edge 221 is an extending direction Y. The distance from the reference end edge 222 to the blocking end edge 221 is a blocking distance L1, and the reference end edge 222 is connected to the coupling hole 231. The distance is a pivoting path L2, which is offset The height L1 is smaller than the pivoting diameter L2, that is, the height of the blocking edge 221 in the extending direction Y is smaller than the height of the coupling hole 231 in the extending direction Y, with the reference edge 222 as a reference. The coupling portions 21 of the coupling members 20 are respectively disposed in the accommodating spaces R of the adjacent coupling members 20, and the coupling members 20 are inserted through the coupling holes 231 and the corresponding holes 211 of the coupling members 20 to make the coupling members 20 The pin A is pivotally coupled; one end of the passive member 30 has a force receiving portion 31, and the other end of the passive member 30 is pivotally coupled to one of the coupling members 20.
各該耦合件20以該插銷A為樞軸樞轉，各該耦合件20於樞轉時受鄰近耦合件20之擋抵端緣221的擋抵而限位，藉此，各該耦合件20可樞轉的範圍及角度便為該擋抵端緣221與該插銷A於該延伸方向Y之相對位置決定，又該插銷A係穿設於該結合孔231，是以該插銷A及該結合孔231於該延伸方向Y之位置係相互對應，由前述可知各該耦合件20可樞轉的範圍及角度亦能夠以該擋抵端緣221與該結合孔231於該延伸方向之相對位置決定。 Each of the coupling members 20 pivots with the latch A, and each of the coupling members 20 is limited by the abutting end edge 221 of the adjacent coupling member 20 when pivoting, whereby each of the coupling members 20 The pivotable range and angle are determined by the relative position of the blocking end edge 221 and the latch A in the extending direction Y, and the latch A is threaded through the coupling hole 231, and the latch A and the combination are The positions of the holes 231 in the extending direction Y correspond to each other. It can be seen from the foregoing that the range and angle at which the coupling members 20 can be pivoted can also be determined by the relative positions of the blocking end edges 221 and the coupling holes 231 in the extending direction. .
習知萬向套筒以該基準端緣222為基準時，該擋抵端緣221於該延伸方向Y之高度較結合孔231於該延伸方Y向之高度小，是以，各該耦合件20以該插銷A為樞軸樞轉超過180度才會被該擋抵端緣221擋抵，各該耦合件20以該插銷A為基準可樞轉之角度大於180度，如圖5所示，惟習知萬向套筒於使用時各耦合件20間樞轉角度過大將造成扭曲糾結，甚至無法繼續使用，對使用者造成極大的困擾，是以需要一種具有樞轉角度限制之套筒接頭結構。 When the conventional universal sleeve is based on the reference end edge 222, the height of the abutting end edge 221 in the extending direction Y is smaller than the height of the coupling hole 231 in the extending direction Y, so that each coupling member 20 is pivoted by the latch A for more than 180 degrees to be blocked by the retaining end edge 221, and each of the coupling members 20 can pivot at an angle greater than 180 degrees with respect to the latch A, as shown in FIG. However, when the conventional universal sleeve is used, the pivoting angle between the coupling members 20 is too large, which will cause distortion and entanglement, and even can not be used continuously, which is extremely troublesome for the user, so that a sleeve having a pivot angle limitation is required. Joint structure.

One end of the active member 40 has a force applying portion 41, and the force applying portion 41 is provided with a hand tool In combination, the other end of the driving member 40 is pivotally coupled with one of the coupling members 50; the coupling members 50 have a coupling protrusion 51, a connecting portion 52 and a parallel second blocking portion 53 in sequence. The engaging protrusions 51 define a corresponding hole 511. The two blocking portions 53 define a receiving space O. The two blocking portions 53 respectively define a coupling hole 531 at the corresponding position. The connecting portion 22 and the second blocking portion One end of the portion 53 has a second end flange 521, and the second end edge 521 is located between the two portions 53 to define a direction in which the corresponding hole 511 extends to the end edge 521. X, the corresponding hole 511 The distance from the center of the heart to the end edge 521 is a first stop diameter M1, and the distance from the center of the corresponding hole 511 to the center of the coupling hole 531 is a pivoting diameter M2, and the block diameter M1 is greater than or equal to the pivoting The height M2, that is, the height of the blocking edge 521 in the extending direction X is greater than or equal to the height of the coupling hole 531 in the extending direction X, and the joint portion 51 of each coupling member 50 is 51. The coupling member 50 is pivotally connected to the coupling hole 50 through the coupling hole 531 and the corresponding hole 511 of the coupling member 50. The two sides of the outer peripheral edge of the coupling protrusion 51 of the coupling member 50 respectively have a limiting arc surface 512, and the side wall of the connecting portion 52 facing the receiving space O is an inner side wall 522.

The other end of the passive member 60 is pivotally coupled to one of the coupling members 50. The elastic member S is disposed at the periphery of each of the coupling members 50.
各該耦合件50以該插銷W為樞軸樞轉，且各該耦合件50於樞轉時受鄰近耦合件50之擋抵端緣521的擋抵而限位，藉此，各該耦合件50可樞轉的範圍及角度便為該擋抵端緣521與該插銷W於該延伸方向X之相對位置決定，又該插銷W係穿設於該結合孔531，是以該插銷W及該結合孔531於該延伸方向X之位置係相互對應，由前述可知各該耦合件50可樞轉的範圍及角度亦能夠以該擋抵端緣521與結合孔531於該延伸方向之相對位置決定；於本發明套筒接頭結構中以該對應孔511為基準時，該擋抵端緣521於該延伸方向X之高度大於等於該結合孔531於該延伸方向X之高度，是以各該耦合件50可樞轉之角度便限制在以該插銷W為基準樞轉20~100度，進而限制本發明套筒接頭結構可樞轉之角度。 Each of the coupling members 50 pivots with the latch W, and each of the coupling members 50 is limited by the abutting end edge 521 of the adjacent coupling member 50 when pivoting, whereby each coupling member The pivotable range and angle of the 50 is determined by the relative position of the blocking end edge 521 and the latch W in the extending direction X, and the latch W is threaded through the coupling hole 531, and the latch W and the The positions of the coupling holes 531 in the extending direction X correspond to each other. It can be seen from the foregoing that the range and angle at which the coupling members 50 can be pivoted can also be determined by the relative positions of the blocking end edges 521 and the coupling holes 531 in the extending direction. In the sleeve joint structure of the present invention, when the corresponding hole 511 is used as a reference, the height of the abutting end edge 521 in the extending direction X is greater than or equal to the height of the coupling hole 531 in the extending direction X, so that the coupling is The pivotable angle of the member 50 is limited to pivoting 20 to 100 degrees with respect to the latch W, thereby limiting the pivotable angle of the sleeve joint structure of the present invention.
藉由前述可知，本發明套筒接頭結構係藉由使該耦合件50之該擋抵端緣521於該延伸方向X之位置高於或等於與該結合孔531於該延伸方X向之位置，藉此限制各該耦合件50可樞轉之角度以達成提供一種具有樞轉角度限制之萬向套筒結構的目的。 As can be seen from the foregoing, the sleeve joint structure of the present invention is such that the position of the blocking end edge 521 of the coupling member 50 in the extending direction X is higher than or equal to the position of the coupling hole 531 at the extending direction X. Thereby, the angle at which each of the coupling members 50 can be pivoted is limited to achieve the purpose of providing a universal sleeve structure having a pivot angle limitation.
