Connecting device and fixing structure thereof

Abstract

The invention relates to a connecting device for connecting a first component and a second component and a fixing structure thereof. The fixing structure comprises a component and a connecting piece, the component is provided with an arc-shaped groove for accommodating the connecting piece, and the surface of the connecting piece is provided with an elastic fixing part. When the connecting piece is contained in the arc-shaped groove, the elastic fixing part elastically deforms and abuts against the inner side wall of the arc-shaped groove so as to limit relative movement of the connecting piece and the component. The elastic fixing part on the surface of the connecting piece elastically deforms and abuts against the inner side wall of the arc-shaped groove, so that the sliding friction force between the connecting piece and the inner side wall of the arc-shaped groove is increased, relative movement of the connecting piece and the component is limited, the firmness of the connecting piece in the arc-shaped groove is improved, and the attractiveness of furniture is ensured.

Description

technical field [0001] The invention relates to a connecting device and its fixing structure. The connecting device is used for connecting a first component and a second component, especially for connecting a furniture component or a machine component. Background technique [0002] As people's requirements for the aesthetics of furniture are getting higher and higher, the requirements for connectors used in furniture are also getting higher and higher, so the demand for invisible connectors is also increasing. After the invisible connector is used to assemble the furniture, the connection holes can be hidden, so that the appearance of the furniture has almost no traces of holes, which is more natural and beautiful. At the same time, the installation of the invisible connector is quick and convenient. [0003] At present, there are many kinds of invisible connectors on the market, such as Locklock, Mudeyi, and Lamino, etc. Among them, the structure of the Lamino invisible co...

Problems solved by technology

[0003] At present, there are many kinds of invisible connectors on the market, such as Locklock, Mudeyi, and Lamino, etc. Among them, the structure of the Lamino invisible connector is mainly as the first component of the manufacturing disclosed in the Chinese patent announcement number CN101675256B The connecting mechanism and method for connecting with the second component, such as the connecting device disclosed in the Chinese patent number CN105051382B, and the connecting device and method for connecting two components disclosed in the Chinese patent number CN105940172B, etc., Lamino stealth The connecting piece overcomes the semi-fitting of the fitting with the patent No. DE 19604243C2. When it is loaded into the component, it must enter the holding groove by means of a self-tapping protruding edge, which consumes a lot of energy, and in the case of hard materials such as hardwood, self-tapping The wedging of the type is extremely difficult; at the same time, the automatic wedging cannot be applied to other materials such as Plexiglas or metal materials. It is more convenient to use and has strong versatility

[0004] The above-mentioned non-self-tapping Lamino invisible connectors have corresponding grooves on the components before installation, and the Lamino invisible connectors can be directly It is accommodated in the groove and realizes one-way fixing (along the connection direction), but when the invisible connector is subjected to a force perpendicular to the connection direction, the invisible connector will be displaced in the groove, resulting in a gap between the two components There will be gaps between them, which will affect the aesthetics of the furniture
