Description

Technical Field

[0001] The utility model relates to the technical field of buckles, in particular to a metal buckle. Background Art

[0002] With the development of the construction, industry and decoration industries, snap fasteners have also evolved and updated. Metal snap fasteners are mainly connectors made of metal materials, which are used to embed one part with another or lock the whole part. They are durable and beautiful. They are mainly made by cutting, punching, bending and other mechanical processing processes, as well as surface treatment processes. These processes are more complicated than plastic snap fasteners.

[0003] The existing clips are directly placed between the accessories that need to be connected, and are engaged up and down according to the reserved spaces to complete the connection between the accessories.

[0004] The current buckle limit point is single, and the hand piece is prone to shaking left and right when squeezed by external force, affecting the overall stability. Utility Model Content

[0005] The purpose of the utility model is to provide a metal buckle, aiming to solve the problem that the current buckle has a single limit point and is easy to shake left and right when the hand piece is squeezed by external force, affecting the overall stability.

[0006] To achieve the above-mentioned purpose, the utility model provides a metal clip, including a U-shaped frame, four elastic plate bodies and two extension plates, the U-shaped frame has four trapezoidal holes, the four trapezoidal holes are adapted to the corresponding elastic plate bodies, the four elastic plate bodies are fixedly connected to the U-shaped frame, and are respectively located on the inner top walls of the trapezoidal holes, the two extension plates are fixedly connected to the U-shaped frame, and are respectively located on both sides of the U-shaped frame.

[0007] Place the U-shaped frame on top of the connecting piece, use the structure of the U-shaped frame to buckle it downward, then align the holes on the opponent piece with the U-shaped frame and make it slide down. At this time, the elastic plate body will bend inward at the same time until the opponent piece and the extension plate are in contact with each other. The elastic plate body uses its own characteristics to firmly contact the holes on the opponent piece. In this way, the limit point is increased to avoid left and right shaking when squeezed by external force, thereby ensuring the overall stability.

[0008] Wherein, the metal buckle further includes two triangular barbs, both of which are fixedly connected to the U-shaped frame and are respectively located on the inner bottom wall of the trapezoidal hole.

[0009] The triangular barbs can abut against the outer wall of the connector to fix and clamp the U-shaped frame.

[0010] Wherein, the U-shaped frame and the extension plate have a first arc chamfer.

[0011] The first arc chamfer can not only remove burrs caused by machining, but also facilitate the assembly of parts and eliminate stress concentration.

[0012] Wherein, the elastic plate body has a second arc chamfer.

[0013] The second arc chamfer can not only remove burrs caused by machining, but also facilitate the assembly of parts and eliminate stress concentration.

[0014] Wherein, the metal clip further includes a fastening component, and the fastening component is arranged on one side of the elastic plate body.

[0015] The fastening assembly is added to increase the clamping force of the elastic plate to avoid loosening during assembly.

[0016] In which, the fastening assembly includes a trapezoidal column, a sliding rod, an obtuse-angled plate, a fastening spring and a roller, the trapezoidal column is fixedly connected to the elastic plate body and is located on one side of the elastic plate body, the sliding rod is slidably connected to the trapezoidal column and is located on the inner side wall of the trapezoidal column, the two ends of the fastening spring are respectively fixedly connected to the trapezoidal column and the sliding rod, the obtuse-angled plate is fixedly connected to the sliding rod and is located on one side of the sliding rod, the obtuse-angled plate has a mounting groove, and the roller is rotatably connected to the obtuse-angled plate and is located on the inner side wall of the mounting groove.

[0017] When installing the connecting piece, the roller rolls on the outer wall of the connecting piece. When the elastic plate rebounds outward, the slide rod moves outward in the trapezoidal column, causing the fastening spring to be compressed. When the elastic plate rebounds outward, the characteristics of the fastening spring drive the roller to firmly press against the outer wall of the connecting piece. In this way, the clamping force of the elastic plate is increased to avoid loosening during the assembly process.

[0018] The utility model provides a metal clip, which places the U-shaped frame above the connecting piece, buckles it downward by utilizing the structure of the U-shaped frame itself, and then aligns the holes on the opponent piece with the U-shaped frame to make it slide downward. At this time, the elastic plate body simultaneously bends inward until the opponent piece and the extension plate are abutted. The elastic plate body uses its own characteristics to firmly abut the holes on the opponent piece. In this way, the limit point is increased, which prevents left and right shaking when squeezed by external force and ensures the overall stability. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the elastic plate body 102 is bent inward at the same time until the opponent piece and the extension plate 103 are abutted. The elastic plate body 102 uses its own characteristics to firmly abut the holes on the opponent piece. In this way, the limit point is increased to avoid left and right shaking when squeezed by external force, thereby ensuring the overall stability.
