Description

Chair convenient to assemble

Technical Field

The utility model relates to a chair, in particular to a chair convenient to assemble.

Background

From ancient times and modern times, regardless of the evolution of history, pursuing more comfortable quality of life is always the direction of effort of people, and for supporting a human body and a chair for people to sit, work and rest, the chairs can be divided into a fixed type, a rotary type, a folding type, a combined type, a suspension type, an inflatable type and the like; the chair is divided into a backrest chair, an armchair, a rib chair, a leg-crossing chair and the like according to the shape; and may be further classified according to the use and materials and processing techniques. The known chair made of metal net frame is made by using a punch die to process the metal material to be processed on the punch into the metal net frame, welding the metal net frame on the chair by using the high-frequency oscillation of ultrasonic wave, or welding the asymmetric edge of the metal net frame with the inner side of the chair frame after bending, fixing the asymmetric edge on the chair by using the welding material, wherein the welding method of simultaneously and locally heating the asymmetric edge part and the chair by using the high-frequency oscillation of ultrasonic wave has the following disadvantages: (1) in the welding process, the concentration of harmful gas and smoke dust generated in the working environment is increased according to the increase of the welding point; (2) in order to improve the appearance of the seat 5, the welding point of the seat needs to be processed again by adopting grinding, lapping and polishing tools, and the process is multiple; (3) the back plate or the seat plate is welded and fixed, has a single appearance and cannot be replaced, so that further improvement is needed.

The utility model aims at overcoming the defects of the prior art and providing a chair which is convenient to assemble, has simple structure, convenient installation and use, diversified and beautiful product patterns.

The utility model discloses the purpose is realized with following mode: a chair convenient to assemble which characterized in that: the seat plate frame and the backrest plate frame are hollow rectangular, and the backrest plate net and the seat plate net are respectively fixed in the seat plate frame and the backrest plate frame.

The backup plate frame comprises two rectangular square tubes, the square tubes are distributed at the upper end and the lower end of the back of the backup plate net, and the square tubes are fixed with the backup plate net in a welding mode.

The two sides of the backup plate net extend backwards to form backup plate connecting edges, and fixing bolts penetrate through the backup plate connecting edges to be fixed with the backup rod in a threaded mode.

The periphery of the seat plate net extends downwards to form a seat plate connecting edge, and a fixing bolt penetrates through the seat plate connecting edge to be fixed with the seat plate frame in a threaded manner.

The seat frame, the grab bar and the backrest bar are welded and fixed into a whole.

The two sides of the backrest plate net and the seat plate net are respectively provided with a blocking edge.

The beneficial effects of the utility model are that: 1. simple structure, low production cost and improved market competitiveness. 2. The backrest plate net and the seat plate net are fixed in the seat plate frame and the back frame in a screw connection mode, so that a plurality of fancy backrest plate nets and seat plate nets can be arranged to be matched with the seat plate frame and the back frame, the storage amount and the transportation cost of chair accessories are reduced, bolts are hidden, and the whole appearance is clean and attractive.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. A chair convenient to assemble which characterized in that: the seat plate comprises two symmetrically-installed grab bars 1 and two symmetrically-installed back bars 2, wherein the two grab bars 1 and the two back bars 2 are connected and fixed into a whole through a seat plate frame 3 and a back plate frame 4, the seat plate frame 3 and the back plate frame 4 are in a hollow rectangular shape, and a back plate net 5 and a seat plate net 6 are respectively fixed in the seat plate frame 3 and the back plate frame 4.

The backup plate frame 4 comprises two rectangular square pipes 41, the square pipes are distributed at the upper end and the lower end of the back of the backup plate net 5, and the square pipes are fixed with the backup plate net 5 in a welding mode.

Two sides of the backup plate net 5 extend backwards to form backup plate connecting edges 51, and the fixing bolt 7 penetrates through the backup plate connecting edges 51 to be fixed with the backup rod 2 in a threaded mode.

The periphery of the seat plate net 6 extends downwards to form a seat plate connecting edge 61, and the fixing bolt 7 penetrates through the seat plate connecting edge 61 to be fixed with the seat plate frame 3 in a threaded mode.

The seat plate frame 3, the grab bar 1 and the backrest rod 2 are welded and fixed into a whole.

And blocking edges 8 are respectively arranged at the two sides of the backup plate net 5 and the seat plate net 6.

The working principle is as follows: when the chair is produced, the seat frame 3 is manufactured firstly, and then the seat frame, the armrest rod 1 and the backrest rod 2 are welded and fixed into a whole. Then, the square tube is used for manufacturing the backrest plate frame 4, the backrest plate frame 4 and the backrest plate net 5 are welded and fixed into a whole, and finally the backrest plate net 5 is respectively fixed on the grab rail through bolts 7. The seat plate net is fixed in the seat plate frame 3 through bolts. Wherein, because by lath 5 and bedplate net 6 for sheet metal preparation form, consequently, can be through seting up the pattern of different shapes on its surface to form the bedplate frame 3 and the backup plate frame 4 of different styles, match the product sale of different models through bedplate frame 3 and backup plate frame 4 and bedplate frame 3 and the backup plate frame 4 that the welding constitutes. When the chair is used in the later period, if the backrest plate net 5 and the seat plate net 6 are damaged or the style needs to be changed, the new backrest plate net 5 and the new seat plate net 6 can be replaced by detaching the fixing bolts, so that the whole chair does not need to be replaced, the service life is prolonged, and the use cost is reduced.

Wherein, it needs to be explained that: the backup plate net 5 both sides in the present case extend backward has backup plate to connect limit 51, and the thickness that the limit 51 was connected to the backup plate is less than or equal to the thickness of square pipe for 7 installation back fixing bolt hide behind its main part in the backup plate net back, simultaneously, lean on 6 both sides of plate net 5 and bedplate net to be equipped with respectively and shelter from limit 8, sheltered from the bolt, thereby kept the clean and tidy pleasing to the eye of its appearance, so can extensively use widely.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed.
