Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a chair with an embedded mounting piece. Background Art

[0002] With the development of the times, leisure chairs for leisure and negotiation have gradually entered our field of vision. People not only require leisure chairs to bring relaxation and comfort, but also have higher requirements for the aesthetic appearance and stability of the chairs, and safety factors are highly considered. At the same time, the convenience of installation is also very high, including the simplification of accessories, etc. At present, most leisure chairs on the market are a combination of plastic backrests and steel pipe chair frames or bentwood backrests and steel pipe chair frames. However, since the seat plate and the backrest are a one-piece structure, they can only be processed in the same color and cannot be separated by color. The appearance diversity is limited; some chairs use a combination of plastic backrests + bentwood seat plates, but firstly, due to the large force on the backrest, the embedded parts are easily pulled out if the backrest and the seat plate are only connected by screws, resulting in the risk of the backrest breaking. Secondly, in order to meet the force strength, the backrest generally needs to be connected to the bottom of the chair frame, so the bottom of the chair frame needs to be welded with a relatively thick iron plate, which has a relatively high processing cost, and since most chair frames are arc-shaped, it is difficult to ensure the accuracy of welding, which brings great difficulties and troubles to the installation of the chair. Based on the above technical defects, this application has made an innovative design for the seat plate. The internal design of the seat plate uses multi-layer board pressing to attach the mounting parts. No screw holes can be seen on the seat surface, which looks good. The nuts on the back can be safely and effectively embedded in the curved wood board, ensuring the tight connection between the backrest and the seat plate, avoiding the risk of the nuts being pulled out, and perfectly solving the above problems. It can be widely used in furniture chair products. Utility Model Content
