Embodiment 1 A buckle 1, the buckle 1 is an integrated groove structure, including a horizontal part 2, the two sides of the horizontal part 2 are connected with a symmetrical outward expansion part 3 folded upward obliquely, the outward expansion The part 3 is connected with the draw-in groove part 4 in the vertical direction, and the draw-in groove part 4 is connected with the inwardly bent groove part 5, and the groove part 5 on one side has a turning part 6, and the other side does not; the center of the horizontal part 2 Through holes 10 are provided. Specifically, the projected length of the buckle is 40*46*26mm, and the length of the groove is 5mm.

Specifically, during use, the buckle 1 clamps the ground flat iron 7 through the upper and lower grooves 4 without loosening, so it needs to have sufficient mechanical strength to support the ground flat iron 7 to ensure that it is on the same horizontal plane and is easy to install. In this way, the requirements for the buckle processing technology are relatively high, and there are also certain requirements for the elasticity and strength of the material itself. During the initial production, steel strips with a thickness of 1-3mm were manually processed on-site according to the design drawings. The finished products after semi-manual processing were not high in quality, craftsmanship, and strength, and could not meet the design requirements after testing. Non-manual processing can be completed. After inspecting the market, it is finally formed by mechanical mold opening and stamping. The material is galvanized steel plate with a thickness of 3mm. After cutting, opening, two times of stamping flow-through process, repeated testing, adjustment of molds, and retesting, the qualified product required by the design is finally completed. The buckle prepared in this example better solves the shortcomings of traditional construction procedures such as cumbersome, long time, and high labor and cost costs. It has the characteristics of good appearance quality, convenient and fast installation, high quality, safety and environmental protection, and material saving and consumption reduction.
