Chair with simple and firm installation structure

Abstract

The invention relates to the field of furniture, and particularly relates to a chair with a simple and firm installation structure. The chair comprises chair legs, a chair back, a seat frame and a seat plate, wherein a surrounding plate is connected among the chair legs; the chair legs and the surrounding plate form the seat frame; metal connecting pieces are arranged on the four corners of the seat frame; each metal connecting piece at least comprises a connecting surface in the middle and clamping surfaces at the both ends; a certain bending degree is formed between the two clamping surfaces and the connecting surface; a bolt hole used for installing a screw rod is formed on the connecting surface; the two clamping surfaces are clamped in clamping grooves on the two adjacent surfaces of the seat frame respectively; installing surfaces attached to the bottom surface of the seat plate are arranged on the tops of the metal connecting pieces; and bolts holes are formed on the installing surfaces. The chair disclosed by the invention is simple in structure, firm and reliable, convenient for installation, capable of meeting customer demands and being installed by selecting a manufacturer or by a customer according to customer requirements, durable in use, simple and convenient to install, capable of being installed after being sprayed with a paint, good in spraying and polishing effects, simple and fast in installation, and space-saving; and the chair with the structure is greatly shortened in production cycle, and capable of realizing mechanized and large-scale production.

Description

technical field [0001] The invention relates to the field of furniture, in particular to a chair with a simple and firm installation structure. Background technique [0002] Nowadays, there are many kinds of furniture in the furniture market, and people's requirements for furniture are getting higher and higher, especially the demand for residential furniture has changed from the previous concept that a set of furniture will last a lifetime. The processing methods, technical level of workers, and supply of raw and auxiliary materials cannot meet the conditions for rapid furniture production. For the needs of the general society, the development of the furniture industry is also developing rapidly. [0003] In the traditional manufacturing concept, furniture manufacturers generally adopt the process of assembling first and then spraying paint. In terms of the production process of chairs, this process is adopted because of the limitation of the installation structure of t...

Problems solved by technology

[0007] 4. After spraying, it is not convenient for grinding. Even if there is a grinding process in the current process, the fineness of grinding cannot be achieved because of the installation;

[0008] 5. When the seat plate is connected to the seat frame, because the wooden triangular wood is not firm and easy to be damaged, it cannot meet the requirements of modern people for furniture that can be moved at any time after installation;

[0009] 6. Because it is sprayed after installation, it takes up a lot of space in the production, so it will take up a lot of space in the middle of the transportation process, and it is time-consuming and laborious. The height of the packaging carton is high, the cost is high, the transportation cost increases, and the transportation greater risk of damage

[0010] Or now there are also installation holes directly set between the chair legs and the enclosure, especially the installation holes for fixing bolts on the enclosure. The axial direction of the installation hole is consistent with the length direction of the enclosure. If there is a certain space for installation, then the end of the installation hole is provided with a groove of a certain width on the coaming plate for the operation of the installation tool, and special tools are required

This kind of installation structure, in the process of production, the processing of the hoarding is more difficult, and the installation is inconvenient. At the same time, the hoarding is drilled with installation holes and grooves, so firstly the hoarding is required to have a certain thickness, and secondly, the hoarding should be correspondingly The position is relatively weak and easily damaged

Therefore, this kind of installation structure has many defects, it is not easy to process, it is not easy to install, and special installation tools are required. Compared with the coaming part, it is more wasteful of materials, and it is relatively more prone to damage, and the stability of the installation and molding is not good.
