Problems solved by technology
[0002] In our daily life, we sometimes encounter products such as cabinets or drawers spliced by multiple metal sheet metal parts. The various metal sheet parts are usually assembled by welding, riveting and screw fixing, so they The various metal sheet metal parts cannot be disassembled or separated or the disassembly is cumbersome. The products that cannot be disassembled are large in size, resulting in very high packaging and transportation costs; and the products that are fixed and connected by screws, although the various metal plate parts can be disassembled packaging, but it is very troublesome and complicated for consumers to install after purchase
Therefore, the current connection methods between the metal sheet parts of this type of product cannot be disassembled, resulting in an increase in transportation costs, thereby affecting product sales and waste of resources; or because of cumbersome assembly, it will affect consumers' desire to buy and affect product sales.

Embodiment Construction
[0015] A connection structure between metal sheets, such as Figures 1 to 5 As shown, it includes at least two intersecting and connected sheet metals 1. One of the connecting parts of the two adjacent sheet metals is a female arc 2 that is bent into an open shape, and the other is formed by a bent transition edge 4 and at the The outer end of the transition edge 4 is bent into an open-shaped sub-arc 3; the sub-arc 3 is matched with the mother arc 2 and they are concentric arcs, and the transition edge 4 and the sub-arc 3 are formed. Tangent. We know that products with a certain accommodation space (such as cabinets, drawers, etc.) are often made of multiple sheet metal parts. The connection parts of arcs or sub-arcs. Usually, the connection parts of the same sheet metal part are sub-arcs or mother-arcs to facilitate large-scale production. The parent arc 2 is the superior arc (in geometry, the arc greater than 180 degrees is called the superior arc), and is tangent to the s...

The invention discloses a connecting structure used between sheet metal parts. According to the connecting structure, a main arc sleeve and a sub arc sleeve are concentrically stacked together so as to connect the adjacent sheet metal parts, and therefore all the sheet metal parts can be spliced into various products such as a cabinet and a drawer with certain containing spaces by matching the main arc sleeves and the sub arc sleeves; after being spliced, all sheet metal parts can be fixed into a whole through anti-off pieces; when disassembly is needed, the anti-off pieces are detached from the corresponding sub arc sleeves, the sheet metal parts are separated from one another piece by piece to be laminated together, and therefore the size of the products is reduced, the products can be moved and transported quite conveniently, the transportation cost is saved, meanwhile, the assembly and disassembly are quite simple and convenient, and the market competitiveness of the products is improved; and the connecting parts of the adjacent sheet metal parts are formed by sleeving the main arc sleeves with the sub arc sleeves so as to enhance the rigidity of the products formed by connecting the sheet metal parts, and therefore the structure of the connecting structure is reasonable, the assembly and disassembly of the sheet metal parts are facilitated, and the rigidity of the productsformed by connecting the adjacent sheet metal parts is enhanced.
Description
technical field [0001] The present invention relates to metal sheet metal parts, in particular to a connection structure between various metal sheet metal parts. Background technique [0002] In our daily life, we sometimes encounter products such as cabinets or drawers that are spliced by multiple metal sheet metal parts. The metal sheet parts are usually assembled by welding, riveting and screw fixing. Therefore, they are The various metal sheet metal parts of the product cannot be disassembled or disassembled, and the products that cannot be disassembled are very expensive due to their large size, resulting in very high packaging and transportation costs; while the products that are connected by screws, although the various metal plate accessories can be disassembled Packaging, but the installation of consumers after purchase is very troublesome and complicated. Therefore, the current connection method between the metal sheet parts of this type of products either canno...
