Connection fitting of household product

Abstract

The invention relates to a connection fitting of a household product, which comprises a fitting body and a screw, wherein the screw comprises a screw head and a screw rod, and the screw rod is dividedinto a positioning section and a connecting section; a special-shaped channel in a racket shape is arranged on the fitting body and comprises a channel in a racket plate shape and a channel in a racket rod shape; a toothed body with an expansion function is arranged on the peripheral surface of the fitting body to form a first toothed surface, and at least a pair of positioning grooves and at least a pair of clamping strips which extend to two sides are respectively arranged symmetrically in the axial direction of the first toothed surface; two inner side surfaces of the channel in the racketrod shape on the fitting body form a second toothed surface; the distance between the two toothed surfaces is slightly smaller than the external diameter of the positioning section of the screw rod;a pair of inclined third toothed surfaces are formed between the second toothed surface and the back surface of the fitting body; and the integral gradient of each third toothed surface is matched with the external form of the bottom of the screw head, and the junction of each third toothed surface and the second toothed surface is slightly higher than the positioning section of the screw rod. Thefitting body can be fixed without using any screw thread, can be quickly assembled, and has high construction efficiency and firm connection.

Description

technical field [0001] The invention belongs to the technical field of hardware fittings, and relates to a connection fitting for household products. Background technique [0002] For a long time, there are generally the following types of assembly structures for household products: [0003] 1. Use iron nails to connect and fix. It belongs to the most traditional assembly method. With this assembly structure, countless screw heads will be left on the surface of wooden products, making the surface uneven, which is not beautiful and will affect the effect of paint. The screws will rust after a long time , is also not conducive to disassembly. [0004] 2. Use drilling screw to connect and cover. Compared with the above-mentioned iron nail connection structure, the surface flatness of this assembly structure has been improved, but the construction is time-consuming and laborious, and the work efficiency is low. Once the cover at the drilled hole is lost during use, the surfac...

AI Technical Summary

Problems solved by technology

At least two or more fittings are required on each tread, usually four, with at least three screw holes on each fitting, so this type of connection is particularly inefficient

[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 will make the connection part loose, which will directly affect the connection firmness between the tread plate and the vertical plate or the beam plate
