Description

Safety Buckle Combination Structure Improvement

The present invention is related to the improvement of a combination structure of a safety buckle, especially a combination forming Safety buckle, the structure is stabilized by assembling to achieve the function of safety buckle that is easy to process and enhances the safety of use.

Press, the seat belt is to prevent riding or driving vehicles and other means of transportation, reduce collision or impact When hitting, the passenger and the driver can be fixed on the seat to prevent the occurrence of flying and reduce the occurrence of secondary injuries. According to different types of needs, there are different seat belts to protect the user, such as being tied around the waist The horizontal beam type and other three-point, four-point, five-point seat belts are more common; The seat belt will not be easily disengaged when being impacted, and more importantly, it can withstand a strong pulling force when being impacted, and after protecting the user, the user can easily open the seat belt and disengage. In addition to the stability of the structure, the choice of materials is also limited by the tensile conditions. Therefore, there is a more simple structure, which is forged from metal materials and uses a known competitive seat belt buckle device (as shown in Figure 5), including: A buckle 5 and a plug-in buckle 6, wherein the buckle 5 is a forged convex seat plate 51, a horizontal long hole 511 is set on the wider section, and one side plate 512 and two side plates 512 are bent on each side A clamping rod 52 that can slide freely is arranged in between, and the seat belt on one side can be connected through the clamping rod 52 through the horizontal long hole 511. A trigger lever 53 and a group of spring steel ball buckle units 54 are provided. One end of the trigger lever 53 is provided with a trigger part 531, and the other end is provided with a hook part 532. The two sides of the middle section are provided with opposite buckle grooves 533. The buckle 6 is composed of a convex-shaped plate 61, a horizontal long hole 611 is set on the wider section, one side plate 612 is bent on each side, and a clamping rod 62 that can slide freely is set between the two side plates 612. This horizontal long hole 611 can be used to cooperate with the clamping rod 62 to connect the safety belt on the other side. A buckle hole 63 is provided at the end of the narrower section, and a soft gasket is riveted and fixed on the buckle 6 . When using buckle, turn the pull lever 53 so that the buckle slot 533 in the middle part is separated from the buckle unit 54 of the buckle 5, and pivot to open to a certain angle, and then the narrower end of the buckle 6 is insert part into the frame body 513 of the buckle 5, reversely turn the lever 53 so that the hook part 532 hooks the hook hole 63 of the narrower section of the buckle 6, and the buckle in the middle section of the lever 53 The slot 533 is buckled and positioned by the buckling unit 54 of the buckle 5 to complete the buckling action. When you want to untie the seat belt, turn the buckle lever 53 to open, so that the buckle groove 533 in the middle section is separated from the buckle unit 54 of the buckle 5, and pivot to open to a certain angle, so that the hook of the buckle lever 53 The buckle part 532 disengages from the hook hole 63 of the narrower section of the buckle 6, and then the narrower section of the buckle 6 can be pulled away from the frame 513 of the buckle 5 to complete the unlocking action.

However, according to the above, it can be known that the conventional safety buckle structure needs to be forged in processing, And follow-up drilling construction is required, and installation after processing is completed, and it is necessary to check whether there are cracks in the forging material during processing, and the cracks produced by forging are not only easy to pick out when they are visible to the naked eye, but also subtle cracks are difficult to pick out. Perceived, it is necessary to pay attention to various conditions in the forging process to ensure that cracks are reduced after forming, and forging will have oxidation, which makes the finished product easy to generate oxides on the surface, resulting in different sizes of the finished product, so it is easier to drill holes around the periphery of the hole The thickness is different, which affects the overall mechanical strength. Therefore, forging needs to increase the thickness to make the overall structure stable. Therefore, the safety buckle manufactured by forging is not only cumbersome to produce, but it is easy to find that the finished product is defective in the later stage of processing, resulting in waste of resources. The finished product produced by forging is that the processing process takes more time, which is actually a major drawback and needs to be improved urgently.
