Description

安全扣組合結構改良Improved safety buckle combination structure

本發明係與一種安全扣組合結構改良有關，尤指一種組接成形之安全扣，藉由組接方式使結構穩定，以達到便於加工且提升使用安全性之安全扣功能者。 The present invention relates to an improved safety buckle assembly structure, in particular to an assembled and formed safety buckle, which can stabilize the structure through the assembly method, so as to achieve the function of a safety buckle that is convenient for processing and enhances the safety in use.

按，安全帶是防止乘坐或駕駛車輛等交通工具，減少衝撞或受衝擊時，可以將乘客及駕駛固定於座位上，防止有拋飛的情況發生，降低二次傷害的產生，而依照不同種類需求，更有不同的安全帶，以保護使用者，如束於腰部的橫束式及其他三點式、四點式、五點式安全帶等較為常見；而安全帶除了在受到衝擊時不會輕易脫離外，更重要的是，受衝擊時能夠承受強大的拉力，並於保護使用者後，使用者能夠輕易的打開安全帶而脫離，因此安全帶除了結構需要穩定外，材料的選擇也受到抗拉條件的限制，因此，更有一種結構簡便，藉由金屬材料鍛造使用習知之競技用安全帶扣合裝置(如第5圖所示)，包含：一扣具5及一插扣件6，其中扣具5係由一鍛造成型之凸字形座板51，較寬段上設置一橫向長孔511，兩側各彎設一側板512，兩側板512間組設一可自由滑動之卡制桿52，而可藉該橫向長孔511配合卡制桿52供一側之安全帶穿套連結，較窄段末端彎設一框體513，較窄段上樞設一扳扣桿53及設置一組彈簧鋼珠卡扣單元54，該扳扣桿53一端設置一扳柄部531，另端設置一勾扣部532，中段兩側設有相對之卡扣槽533，插扣件6係由一凸字狀板片61，較寬段上設置一橫向長孔611，兩側各彎設一側板612，兩側板612間組設一可自由滑動之卡制桿62，而可藉該橫向長孔611配合卡制桿62供另側之安全帶穿套連結，較窄段端部設置一勾扣孔63，插扣件6上鉚設固結一軟性墊片。使用扣合時，將扳扣桿53扳轉，令其中段之卡扣槽533脫離扣具5之卡扣單元54，並樞轉開啟至一定角度，接著將插扣件6之較窄段端部***扣具5之框體513內，反向扳轉扳扣桿53，使其勾扣部532勾扣插扣件6較窄段之勾扣孔63，並且扳扣桿53中段之卡扣槽533受扣具5之卡扣單元54卡扣定位，完成扣合動作。另欲解開安全帶時，將扳扣桿53扳轉開啟，令其中段之卡扣槽533脫離扣具5之卡扣單元54，並樞轉開啟至一定角度，使扳扣桿53之勾扣部532脫離插扣件6較窄段之勾扣孔63，則即可將插扣件6之較窄段抽離扣具5之框體513，完成解開動作。 Press, seat belts are used to prevent vehicles such as riding or driving vehicles, reduce collisions or shocks, and can fix passengers and drivers on the seat to prevent the occurrence of flying and reduce the occurrence of secondary injuries, and according to different types demand, there are more different seat belts to protect the user, such as the horizontal harness tied to the waist and other three-point, four-point, five-point seat belts, etc. are more common; and seat belts are not easy to be affected except when they are impacted. In addition to detachment, more importantly, it can withstand a strong pulling force when impacted, and after protecting the user, the user can easily open the seat belt and detach. Therefore, in addition to the structural stability of the seat belt, the choice of material is also subject to resistance. Due to the limitation of pulling conditions, there is a more convenient structure, which is forged by metal materials and uses a conventional seat belt buckle device for competition (as shown in Figure 5), including: a buckle 5 and an insert buckle 6, The buckle 5 is made of a convex seat plate 51 formed by forging, a lateral long hole 511 is arranged on the wider section, a side plate 512 is bent on each side, and a freely slidable clamping rod 52 is assembled between the two side plates 512 , and the lateral long hole 511 can cooperate with the locking rod 52 to connect the safety belt on one side. A toggle lever 53 and a set of spring steel ball snap units 54 are pivoted on the segment. One end of the toggle lever 53 is provided with a toggle portion 531, the other end is provided with a hook portion 532, and opposite snap grooves are provided on both sides of the middle section. 533, the buckle 6 is composed of a convex plate 61, a lateral long hole 611 is arranged on the wider section, a side plate 612 is bent on each side, and a freely slidable clamping rod 62 is assembled between the two side plates 612 , and can use the transverse long hole 611 to cooperate with the locking rod 62 for the other side of the safety belt to connect. When using the clasp, turn the clasp lever 53 so that the clasp groove 533 of the middle section is separated from the clasp unit 54 of the buckle 5 and pivoted to a certain angle, and then the narrower end of the buckle 6 is opened. The first part is inserted into the frame body 513 of the buckle 5, and the pull lever 53 is reversely turned, so that the hook portion 532 hooks the hook hole 63 of the narrower section of the clip 6, and the middle section of the pull lever 53 is locked. The slot 533 is locked and positioned by the locking unit 54 of the locking device 5 to complete the locking action. In addition, when the seat belt is to be unfastened, the trigger lever 53 is turned to open, so that the locking groove 533 in the middle part is separated from the buckle unit 54 of the buckle 5, and is pivoted to a certain angle, so that the hook of the trigger lever 53 is opened. When the buckle portion 532 is disengaged from the hook hole 63 of the narrower section of the clip 6 , the narrow section of the clip 6 can be pulled out of the frame 513 of the clip 5 to complete the unlocking action.

然，據上述可得知，習知安全扣結構在加工上需要鍛造成形，且後續需要進行鑽孔的施工，並在加工完成後進行安裝，且需要檢查鍛造材料於加工中是否有裂痕，而鍛造產生的裂痕除了肉眼可見的狀態容易挑出來外，更有細微的裂痕難以察覺，使得必須要注意在鍛造過程的各種條件，確保成形後降低裂痕，而鍛造會有氧化作用，使成品容易於表面生成氧化物，導致成品尺寸不一，因此更容易在鑽孔後孔洞周緣厚度不一樣，影響到整體機械強度，因此，鍛造更需要提高厚度，使整體結構穩定，因此鍛造方式製造的安全扣不但生產繁瑣，且容易在後段加工時才發現成品不良，造成資源浪費，且鍛造產生的成品在於加工過程更需要時間，實為一大弊端問題，而亟待加以改良。 However, according to the above, it can be known that the conventional safety buckle structure needs to be forged in processing, and then needs to be drilled and installed after the processing is completed, and it is necessary to check whether the forging material has cracks during processing, and In addition to the cracks that are visible to the naked eye, the cracks produced by forging are easy to pick out, and more subtle cracks are difficult to detect, so it is necessary to pay attention to various conditions in the forging process to ensure that the cracks are reduced after forming, and forging will have oxidation. Oxides are formed on the surface, resulting in different sizes of finished products, so it is easier to have different thicknesses around the hole after drilling, which affects the overall mechanical strength. Therefore, forging needs to increase the thickness to make the overall structure stable. Therefore, the safety buckle made by forging is not only cumbersome to produce, but also easy to find defective finished products in the later processing, resulting in waste of resources, and the finished products produced by forging require more time in the processing process. , which is a major drawback and needs to be improved urgently.
