Structure of fitting for assembled furniture

Abstract

The invention belongs to the field of machinery, discloses a structure of a fitting for assembled furniture. The fitting structure comprises a fitting body; a joining hole is provided in the fitting body; the joining hole is perpendicularly extended from the top to the back; an expansion groove is formed in the joining hole and enables the groove wall of the joining hole and the fitting body to moderately extend along the radial direction of the joining hole; latches are equipped at the mouth or wall of the expansion groove; the axial external surface of the fitting body is a tooth-shaped surface or a threaded surface or a smooth surface, the peripheric dimension of the fitting body is slightly greater than the diameter of the groove on the internal side of the sheet for a household product; and the cross section of the groove of the sheet for the household product is shaped to be matched with the fitting body profile, which enables the fitting body to be fixed in the groove of the household product without using any screws; then, the furniture can be assembled rapidly, the working efficiency is high, and connection is firm.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a combined furniture fitting structure, in particular to a fitting body that can be positioned in a groove of a furniture board without using screws, so as to achieve the purpose of convenient assembly. Background technique [0002] For a long time, there are roughly the following types of assembly structures for home products: [0003] 1. Directly connect and fix with iron nails. It belongs to the most traditional assembly mode. When wooden products are assembled in this way, countless screw heads will be left on the surface to make the surface uneven, which is not beautiful and will affect the effect of paint. It will rust and is not conducive to disassembly. [0004] 2. Use drilling screws to connect the capping mode. Compared with the above-mentioned iron nail connection structure, the surface flatness of this assembly structure has been improved, but the construction is time-consum...

AI Technical Summary

Problems solved by technology

At least two or more fittings need to be installed on each step board, usually four, and each fitting has at least three screw holes, so the effect of this connection mode is particularly low

[0010] At the same time, since the two inner surfaces of the fitting body and the screw rod of the screw are both smooth, during use, the relative position between the fitting body and the screw will be affected by factors such as vibration or external forces from various directions. The change makes the connection part loose, which directly affects the firmness of the connection between the tread plate and the vertical plate or the beam plate, thus leaving a safety hazard in the use of stairs
