一連桿20，係配合該鉤本體10的開口12長度設計，設有第一桿端21及第二桿端22，該第一桿端21設有第一缺槽211及固定桿212，該第二桿端22設有一第二缺槽221及凹孔222，另該連桿20近第二桿端22處設有一溝槽23及一配合溝槽23的C型扣24，該連桿20以第二桿端22與鉤本體10的第二端14樞設樞轉，使該連桿20第一桿端21的固定桿212能以轉動的動作扣入或離開該溝槽131，而該連桿20近第一桿端21處設有一固定孔25。 The first rod end 21 and the second rod end 22 are provided with a first rod end 21 and a second rod end 22, and the first rod end 21 is provided with a first notch 211 and a fixing rod 212. The second rod end 22 is provided with a second notch 221 and a recessed hole 222. The connecting rod 20 is provided with a groove 23 near the second rod end 22 and a C-shaped buckle 24 engaging with the groove 23, the connecting rod 20 The second rod end 22 is pivoted with the second end 14 of the hook body 10 so that the fixing rod 212 of the first rod end 21 of the connecting rod 20 can be buckled into or away from the groove 131 by a rotating action. The connecting rod 20 is provided with a fixing hole 25 near the first rod end 21.
一扳動彈性件30，設於鉤本體10第二端14的彈性結合槽141與該連桿20第二桿端22的凹孔222間，使該連桿20產生一使該連桿20的固定桿212能扣入該溝槽131的彈性，常態關閉該開口12。 A resilient member 30 is disposed between the elastic coupling groove 141 of the second end 14 of the hook body 10 and the recess 222 of the second rod end 22 of the connecting rod 20, so that the connecting rod 20 generates a connecting rod 20 The fixing rod 212 can be buckled into the elasticity of the groove 131, and the opening 12 is normally closed.
一固定件40，凸出設於該連桿20靠近第一桿端21方向，該固定件40係利用插設方式設於該固定孔25中。 A fixing member 40 is protruded from the connecting rod 20 in the direction of the first rod end 21, and the fixing member 40 is disposed in the fixing hole 25 by means of insertion.
一旋轉套50，套設於該連桿20上，並相對該連桿20及該固定件40產生軸向的轉動，該旋轉套50對應該固定件40位置設有由低至高且旋轉的調整槽51，該調整槽51具有一低部511及一高部512，且低部511的上方有一垂直該固定件40的擋止面513，另該旋轉套50對應第一端13設有限制面52，該旋轉套50對應該溝槽23方向設有一彈性限位部53。 A rotating sleeve 50 is sleeved on the connecting rod 20 and generates axial rotation relative to the connecting rod 20 and the fixing member 40. The rotating sleeve 50 is provided with a low to high and rotating adjustment corresponding to the position of the fixing member 40. The groove 51 has a lower portion 511 and a high portion 512, and a lower surface 511 has a blocking surface 513 perpendicular to the fixing member 40. The rotating sleeve 50 has a limiting surface corresponding to the first end 13. 52. The rotating sleeve 50 is provided with an elastic limiting portion 53 corresponding to the direction of the groove 23.
該固定件40凸出於該調整槽51中，該旋轉套50並以調整槽51順著該固定件40在該連桿20產生旋轉同時升降的動作，當該固定件40凸出在低部511則限制面52涵蓋到該鉤本體10的第一端13，使該連桿20被限位而封 閉該鉤本體10的開口12，當該固定件40凸出在高部512則限制面52離開該鉤本體10的第一端13，使該連桿20可被下壓樞轉，進而開啟該鉤本體10的開口12。 The fixing member 40 protrudes from the adjusting groove 51, and the rotating sleeve 50 is moved by the adjusting groove 51 along the fixing member 40 while the connecting rod 20 rotates while the fixing member 40 protrudes at the lower portion. 511, the limiting surface 52 covers the first end 13 of the hook body 10, so that the connecting rod 20 is restrained and sealed. Closing the opening 12 of the hook body 10, when the fixing member 40 protrudes from the high portion 512, the restricting surface 52 is separated from the first end 13 of the hook body 10, so that the connecting rod 20 can be pivoted down, thereby opening the The opening 12 of the hook body 10.
一壓縮彈性件60，設於該連桿20與該旋轉套50間，令該旋轉套50對該固定件40產生一推抵彈性，使該固定件40常態凸出在低部511位置，該壓縮彈性件60一端頂抵該C型扣24，另一端頂抵該彈性限位部53，當轉動該旋轉套50該壓縮彈性件60會被壓縮，這時該固定件40由低部511移動到高部512，當放開該旋轉套50該壓縮彈性件60則彈性復原，令該旋轉套50轉動及位移，這時該固定件40由高部512移動到低部511。 A compression elastic member 60 is disposed between the connecting rod 20 and the rotating sleeve 50, so that the rotating sleeve 50 generates a pushing elastic force to the fixing member 40, so that the fixing member 40 normally protrudes at the lower portion 511. One end of the compression elastic member 60 abuts against the C-shaped buckle 24, and the other end abuts against the elastic limiting portion 53. When the rotating sleeve 50 is rotated, the compression elastic member 60 is compressed, and the fixing member 40 is moved from the lower portion 511 to the lower portion 511. The high portion 512 is elastically restored when the rotating sleeve 50 is released, and the rotating sleeve 50 is rotated and displaced. At this time, the fixing member 40 is moved from the high portion 512 to the lower portion 511.
另該旋轉套50的調整槽51的低部511的下方有一垂直該固定件40的限位槽514，該固定件40常態於該限位槽514中，在轉動該旋轉套50前，必須先施一垂直移動，使該固定件40脫離該限位槽514才能轉動該旋轉套50在該連桿20產生旋轉同時升降的動作。 The lower portion 511 of the adjusting slot 51 of the rotating sleeve 50 has a limiting slot 514 perpendicular to the fixing member 40. The fixing member 40 is normally in the limiting slot 514. Before rotating the rotating sleeve 50, it must first A vertical movement is performed to disengage the fixing member 40 from the limiting groove 514 to rotate the rotating sleeve 50 to rotate while the connecting rod 20 is rotated.
該擋止面513在限制固定件40的垂直移動方向，該限位槽514在限制固定件40的旋轉移動方向。 The stopping surface 513 restricts the vertical movement direction of the fixing member 40, and the limiting groove 514 restricts the rotational movement direction of the fixing member 40.
又，見第三圖與第六圖所示，該旋轉套50對應第二端14延伸出有限制板54，該限制板54於該連桿20樞轉時，係阻擋於該第二端14一側，避免該旋轉套50的轉動，當該連桿20第一桿端21的固定桿212扣入該溝槽131時，該限制板54才能脫離該第二端14的限制，該旋轉套50才能轉動回。 In addition, as shown in the third and sixth figures, the rotating sleeve 50 extends from the second end 14 with a limiting plate 54 that blocks from the second end 14 when the connecting rod 20 pivots. On one side, the rotation of the rotating sleeve 50 is avoided. When the fixing rod 212 of the first rod end 21 of the connecting rod 20 is buckled into the groove 131, the limiting plate 54 can be separated from the restriction of the second end 14. 50 can turn back.
由上述具體實施例之結構，可得到下述之效益：本發明利用壓縮彈性件60推抵旋轉套50對固定件40，以及該旋轉套50對應該固定件40位置設有由低至高且旋轉的調整槽51的設計，具有 旋轉套50方便加工與設置，且壓縮彈性件60的安裝簡易，故能降低個零件的加工成本與安裝成本的優點，在旋轉套50的轉動之間，即可令連桿20與鉤本體10間得到開啟與關閉，進而得到吊掛鉤的安全開關設計，且操作又方便。 According to the structure of the above specific embodiment, the following benefits can be obtained: the present invention utilizes the compression elastic member 60 to push against the rotating sleeve 50 against the fixing member 40, and the rotating sleeve 50 corresponds to the position of the fixing member 40 from low to high and rotates. The design of the adjustment slot 51 has The rotating sleeve 50 is convenient for processing and setting, and the installation of the compression elastic member 60 is simple, so that the processing cost and the installation cost of the parts can be reduced. Between the rotation of the rotating sleeve 50, the connecting rod 20 and the hook body 10 can be obtained. The safety switch design of the hook is obtained by opening and closing, and the operation is convenient.
綜上所述，本創作確實已經達於突破性之結構，而具有改良之創作內容，同時又能夠達到產業上利用性與進步性，當符合專利法之規定，爰依法提出新型專利申請，懇請 鈞局審查委員授予合法專利權，至為感禱。 In summary, this creation has indeed reached a breakthrough structure, and has improved content of creation, while at the same time achieving industrial use and progress. When complying with the provisions of the Patent Law, it proposes a new type of patent application according to law. The census review committee granted legal patent rights and was praying.
