目前已知安全掛鉤，一種如M500829是於鉤本體的開口一端設置一連桿，該連桿可活動閉合該開口，而該連桿上設有外螺紋，一螺帽設於該連桿的外螺紋，利用螺轉方式封閉或開啟連桿與鉤本體的開口間，該方式設計掛鉤雖然強度佳，但是操作使用螺轉的過程非常緩慢且不便。 At present, a safety hook is known. For example, the M500829 is provided with a connecting rod at the open end of the hook body, the connecting rod can movably close the opening, and the connecting rod is provided with an external thread, and a nut is disposed outside the connecting rod. The thread is closed or opened between the connecting rod and the opening of the hook body by means of a screwing manner. Although the designing hook has good strength, the process of using the screwing is very slow and inconvenient.
另一種，如專利第M262607的安全吊掛器，鉤本體的開口一端設置一連桿，該連桿可活動閉合該開口，且該連桿上設有凸點，一旋轉套設於該連桿，且內緣設有一螺旋狀溝槽供凸點定位，令旋轉套可產生限制路徑的升降，該操作雖然方便，然而旋轉套內緣設置螺旋狀溝槽的方式加工極為不易，故其加工成本高。 Another type, such as the safety hanger of the patent No. M262607, a connecting rod is provided at one end of the opening of the hook body, the connecting rod can movably close the opening, and the connecting rod is provided with a bump, and a rotating sleeve is disposed on the connecting rod And the inner edge is provided with a spiral groove for the positioning of the bump, so that the rotating sleeve can generate the lifting and lowering of the limiting path. Although the operation is convenient, the method of setting the spiral groove on the inner edge of the rotating sleeve is extremely difficult to process, so the processing cost thereof is high.
又一種，如申請第102122651號的旋轉下降式安全掛鉤，鉤本體的開口一端設置一連桿，該連桿可活動閉合該開口，且該連桿上設有凸點，一旋轉套設於該連桿，且表面貫穿設置一螺旋狀溝孔供凸點定位，令旋轉套可產生限制路徑的升降，該操作雖然方便，且旋轉套以貫穿加工螺旋狀溝孔也容易且成本低，但該種貫穿的溝孔於操作時手感不佳，且使 用過程容易有塵土由該溝孔掉入，恐有影響連桿正常操作的疑慮。 In another aspect, as claimed in claim 102122651, the open end of the hook body is provided with a connecting rod at one end of the hook body, the connecting rod can movably close the opening, and the connecting rod is provided with a bump, and a rotating sleeve is disposed on the connecting rod The connecting rod has a spiral grooved hole for the surface to be positioned, so that the rotating sleeve can generate the lifting and lowering of the limiting path. Although the operation is convenient, and the rotating sleeve is easy to process and the cost is low, the The through-holes are not pleasant to handle during operation, and Dust is easily dropped from the groove by the process, which may affect the normal operation of the connecting rod.
目前已知的安全吊掛鉤，使用分別有操作方便性、加工難、成本高與操作時手感不佳及塵土由溝孔掉入內部的缺點。 At present, the known safety hooks have the disadvantages of convenient operation, difficult processing, high cost, poor hand feeling during operation, and dust falling into the interior by the groove.

一連桿套40，該連桿套40不受重負荷為塑膠射出、粉末冶金或金屬射出等手段成型，該連桿套40套設於該連桿20上固定，設有一往下方左旋411及右旋412傾斜延伸的旋轉槽41，該旋轉槽41有一限制端413於左旋411及右旋412的中央，且該限制端413靠近該第二桿端22，該限制端413為垂直延伸出一長度不同該左旋411及該右旋412延伸方向，該左旋411及該右旋412延伸靠該第一桿端21方向分別設有末端槽414。 a connecting rod sleeve 40, the connecting rod sleeve 40 is formed by means of plastic injection, powder metallurgy or metal injection, and the connecting rod sleeve 40 is sleeved on the connecting rod 20, and is provided with a leftward rotation 411 and The right-handed 412 is inclined to extend the rotating slot 41. The rotating slot 41 has a limiting end 413 at the center of the left-handed 411 and the right-handed 412, and the limiting end 413 is adjacent to the second rod end 22, and the limiting end 413 extends vertically. The left turn 411 and the right turn 412 extend in different directions, and the left turn 411 and the right turn 412 extend respectively in the direction of the first rod end 21 to provide an end slot 414.
一彈抵元件50，套設於該連桿20，一端頂抵於該連桿20上的固定扣23。 A resilient member 50 is sleeved on the connecting rod 20, and one end thereof abuts against the fixing buckle 23 on the connecting rod 20.
一旋轉套60，套設於該連桿20及該連桿套40上，並可相對該連桿20及該連桿套40產生軸向的位移，該位移可封閉或開啟該連桿20第二桿端22及該鉤本體10第二端14，該旋轉套60表面貫穿有一孔洞61，且鄰近該鉤本體10的第一端13配合該旋轉槽41的左旋411及右旋412端部設有閃避槽62。 a rotating sleeve 60 is sleeved on the connecting rod 20 and the connecting rod sleeve 40, and can generate an axial displacement relative to the connecting rod 20 and the connecting rod sleeve 40, and the displacement can close or open the connecting rod 20 a second rod end 22 and a second end end 14 of the hook body 10. The rotating sleeve 60 has a hole 61 extending through the surface thereof, and the first end 13 of the hook body 10 is matched with the left end 411 and the right end 412 end of the rotating slot 41. There is a dodge slot 62.
該彈抵元件50，套設於該連桿20時，另一端頂抵該旋轉套60，令該旋轉套60的位移後常態封閉該連桿20第二桿端22及該鉤本體10第二端14，同時該孔洞51正好對正該限制端413。 The resilient member 50 is sleeved on the connecting rod 20, and the other end abuts against the rotating sleeve 60, so that the displacement of the rotating sleeve 60 normally closes the second rod end 22 of the connecting rod 20 and the second hook end 10 of the connecting rod 20 End 14, while the hole 51 is exactly aligned with the limiting end 413.
一定位銷70，插設固定於該彈抵元件50的孔洞51，並深入該連桿套40的旋轉槽41的限制端413中，該旋轉套60的升降是以該定位銷70順著該連桿套40旋轉槽41的左旋411或右旋412路徑移動，最後於該末端槽414檔止。 a positioning pin 70 is inserted into the hole 51 of the elastic element 50 and penetrates into the limiting end 413 of the rotating groove 41 of the connecting rod sleeve 40. The lifting and lowering of the rotating sleeve 60 is performed by the positioning pin 70. The left sleeve 411 or the right hand 412 of the rotation groove 41 of the link sleeve 40 moves, and finally stops at the end groove 414.
組合後常態時，該連桿套40旋轉槽41的限制端413在靠近該第二桿端22，且垂直延伸出一長度係往該第二桿端22，該左旋411或右旋412係由連接該限制端413往該第一桿端21方向傾斜延伸。 When the combined normal state, the limiting end 413 of the rotating sleeve 41 of the connecting rod sleeve 40 is adjacent to the second rod end 22, and a length extending perpendicularly to the second rod end 22, the left rotation 411 or the right rotation 412 is The limiting end 413 is connected to extend obliquely toward the first rod end 21 .
當在不施力時，見第三圖及第四圖所示，該連桿20第二桿端22受該回彈元件30的彈性閉合在該鉤本體10的第二端14，使該開口12被封閉該內部空間11也呈現封閉，令該開口12產生第一道防開啟的保護，該旋轉套60並封閉該連桿20第二桿端22及該鉤本體10第二端14，令該開口12產生第二道防開啟的保護。 When no force is applied, as shown in the third and fourth figures, the second rod end 22 of the connecting rod 20 is closed by the elastic force of the resilient element 30 at the second end 14 of the hook body 10, so that the opening 12 is closed, the internal space 11 is also closed, so that the opening 12 produces a first protection against opening, the rotating sleeve 60 and the second rod end 22 of the connecting rod 20 and the second end 14 of the hook body 10 are closed. This opening 12 creates a second protection against opening.
當要開啟該鉤本體10的該開口12，使繩帶進入或離開該內部空間11時，先見第五圖及第六圖所示，將該旋轉套60由該第二桿端22往該第一桿端21方向推，帶動該定位銷70脫離使限制端413，使該旋轉套60可以被轉動，接著轉動該旋轉套60並壓縮該彈抵元件50，見第七圖及第八圖所示，使定位銷70選擇進入該左旋411或該右旋412路徑中，令該旋轉套60配合產生由往該第二桿端22往該第一桿端21方向的位移，當該旋轉套60完全脫離該鉤本體10的第二端14，見第八圖及第九圖所示，同時該閃避槽62對應該第一端 13，即可推動該連桿20及該旋轉套60以該第一端13及該第一桿端21為軸心往該內部空間11樞轉，進而開啟該開口12，此時該第一端13閃避入該閃避槽62。當放開該連桿20及該旋轉套60，該回彈元件30即將該連桿20彈回該開口12，該彈抵元件50接著將該旋轉套60往該第二端14推回，使該旋轉套60再度封閉該第二端14，該定位銷70也回到該限制端413。 When the opening 12 of the hook body 10 is to be opened to allow the cord to enter or leave the inner space 11, as seen in the fifth and sixth figures, the rotating sleeve 60 is moved from the second rod end 22 to the first Pushing the rod end 21 in the direction of the rod, the positioning pin 70 is disengaged from the limiting end 413, so that the rotating sleeve 60 can be rotated, and then the rotating sleeve 60 is rotated and the elastic element 50 is compressed, as shown in the seventh and eighth figures. The positioning pin 70 is selected to enter the left-handed 411 or the right-handed 412 path, so that the rotating sleeve 60 cooperates to generate a displacement from the second rod end 22 toward the first rod end 21 when the rotating sleeve 60 Completely disengaged from the second end 14 of the hook body 10, as shown in the eighth and ninth views, while the dodging slot 62 corresponds to the first end 13, the push rod 20 and the rotating sleeve 60 are pivoted to the inner space 11 with the first end 13 and the first rod end 21 as an axis, thereby opening the opening 12, and the first end 13 flashes into the dodge slot 62. When the connecting rod 20 and the rotating sleeve 60 are released, the resilient element 30 springs the connecting rod 20 back to the opening 12, and the resilient element 50 then pushes the rotating sleeve 60 back toward the second end 14 so that The rotating sleeve 60 again closes the second end 14, and the locating pin 70 also returns to the limiting end 413.
