Find HS Code and trade information for 销子

销子 (xiāo zi) refers to a small, often cylindrical or conical piece used in traditional Chinese joinery, particularly in furniture making. It is a crucial component for securing mortise and tenon joints, offering a robust and reversible fastening method.

Material:

Traditionally, 销子 are crafted from hardwood, typically jujube wood (枣木, zǎomù) due to its strength, density, and resistance to splitting. Other hardwoods like ebony (乌木, wūmù) or rosewood (紫檀木, zìtánmù) can also be employed, especially for higher-quality furniture. Modern examples may utilize bamboo or even synthetic materials, though these are less common in authentic craftsmanship.

Purpose:

The primary function of a 销子 is to lock a mortise and tenon joint together, preventing movement and enhancing structural stability. Unlike glue or metal fasteners, 销子 allow for disassembly and reassembly, a key feature in traditional Chinese furniture design. This is particularly important for pieces intended for transport or future repair.

Function:

A 销子 is inserted through pre-drilled holes in both the tenon and the mortised piece. The tight fit creates a friction-based lock. The diameter of the 销子 is slightly larger than the hole, requiring careful fitting during assembly. The force applied during insertion expands the 销子 slightly, creating a secure hold.

Usage Scenarios:

• Furniture Construction: Used extensively in chairs, tables, cabinets, beds, and other wooden furniture pieces.
• Architectural Joinery: Employed in traditional Chinese architecture for connecting structural components of wooden frames and buildings.
• Repair and Restoration: Essential for repairing damaged mortise and tenon joints in antique or traditional furniture.
• Disassemblable Structures: Ideal for furniture or structures that require frequent assembly and disassembly, such as screens or portable altars.

Common Types:

• Round 销子 (yuán xiāo zi): The most common type, characterized by its cylindrical shape.
• Square 销子 (fāng xiāo zi): Offers greater resistance to rotation, often used in load-bearing joints.
• Conical 销子 (tuī xiāo zi): Provides a particularly tight fit, often used in high-stress applications. These require a tapered hole and are driven in with a mallet.
• Hidden 销子 (cáng xiāo zi): Designed to be concealed within the joint, enhancing the aesthetic appeal of the furniture.
• Through 销子 (tōng xiāo zi): Passes completely through both pieces of wood, offering maximum stability. Often the end is trimmed flush and capped with a decorative element.
