Description
Technical field
The utility model belongs to office appliance and field of furniture, specifically relates to a kind of office chair for office space or house rest etc.
Background technology
At present, after the chair back of seat loads onto screen cloth, the shape face of whole screen cloth just cannot adjust again, thus the problem causing client to use rear screen cloth to fluff affecting product design cannot solve.
Chinese Patent Application No. is the clamping structure that application discloses a kind of seat cloth of 201320457528.2, comprise seat main body, seat main body is by frame section bar welding fabrication, and be provided with backrest, cushion and handrail thereon, cushion and backrest are netted cloth, are arranged on the mounting groove of frame section bar by tension bar tensioning.Frame section bar is provided with mounting groove, and is provided with a clearance groove thereon and passes through for netted cloth, netted cloth both sides are provided with the pilot hole for placing tension bar; When mounted, the side of netted cloth is positioned in mounting groove, and is threaded onto in pilot hole by tension bar, makes it be clamped on clearance groove, and opposite side is stretched by special equipment and is positioned in mounting groove, then makes it be clamped in clearance groove by above-mentioned same step.The technical program is for convenience detach, but conveniently can not adjust the tensile force of netted cloth, when being out of shape when relaxing after netted cloth is due to use a period of time, the tensile force of the netted cloth of adjustment that can not be simple and convenient, cause netted cloth when lax distortion, can only stand or give up, reduce the user satisfaction of user.
