One、Types of connecting components for panel furniture.
1、Off-center connection components/Three-in-one connection components
The concentric wheel connecting component is a crucial part for connecting structural elements in sheet metal furniture. It primarily connects the side panels and horizontal panels, offering quick, secure, and reusable installation, as well as installation in concealed areas without affecting the overall aesthetics. Common concentric connecting components consist of three parts: a concentric wheel, a connecting rod, and a pre-inserted nut, often referred to as a "three-piece" or "three-in-one" connecting component.
2、Dual-purpose connecting component
Common two-in-one screws consist of a hammer head and a connecting rod. The hammer head hole is drilled as a half-hole, and the connecting rod hole on the other plate is drilled as a through-hole. This allows for a screw head to be exposed on the outside, while the hammer head remains hidden inside. Therefore, it is less aesthetically pleasing than a three-in-one screw, but it is more robust.
3、Four-in-one connecting component
This type of heavy-duty connection component consists of four parts and is named accordingly. Although four-in-one connection components have high stability, they are not aesthetically pleasing and are relatively difficult to install, so they are rarely used.
Two. What types of connectors are suitable for furniture made from boards?
1、Appearance Comparison
A two-in-one screw with a pre-drilled hole and a hammer head inserted from the opposite side. However, a three-in-one expansion plug only drills a half-hole, which presents a problem: the offset wheel and hammer head of the three-in-one screw are hidden, while the screw head of the two-in-one screw is exposed due to the pre-drilled hole, resulting in a less aesthetically pleasing appearance compared to the three-in-one.
2- Comparison of connection strength
A two-in-one screw directly connects the screw to the nut and the wood board together, resulting in a much higher connection strength compared to a three-in-one screw that uses a plastic expansion plug. This is what people commonly refer to as "strong and durable."
3、Summary
Overall, while two-in-one connectors are strong, they are not aesthetically pleasing, whereas three-in-one connectors are more visually appealing but have lower connection strength. The specific choice depends on the characteristics of the furniture. For smaller furniture, a more aesthetically pleasing three-in-one connector is preferable. For larger panel furniture, a more robust two-in-one connector is a better option.
