Abstract
The utility model relates to the office chair technical field and in particular to a backrest frame of an office chair. The backrest frame comprises a sitting frame and a back frame which are made from rubber. The outer frames and inner frameworks of the sitting frame and the back frame are all hollow structural plastic plates which consist of two lateral walls and reinforced bars between the two lateral walls. The sitting frame and the back frame are equipped with at least one kind of elastic steel wire or elastic. The sitting frame and the back frame are made from rubber which can be recycled, which does not require wood and reduces lopping forest, and the structure has high intensity, every aspect of advantages of which can replace the sitting frame and the back frame made from wood. In addition, foam is not required to be filled between the elastic steel wires and the sitting frame or the back frame. The backrest frame of the utility model has simple structure and high structural intensity, does not require wood, reduces the quantity of foam greatly, is environmental protective, causes no environmental pollution and has low cost.
Description
Technical field:
The utility model relates to the office chair technical field, refers in particular to a kind of seat back of the body frame of office chair.
Background technology:
The seat back of the body frame of office chair comprises sits frame and back of the body frame two parts, and seat frame and back of the body frame are made with plank, and plank needs a large amount of use timber, and its demand to timber can increase the felling to forest, destroys ecological environment, and its cost height.In addition, give people's comfort, fill between the back side of the seat frame of office chair and back of the body frame and its elastic cord at present and be fitted with foam, and foam is the material of not environmental protection that foam discharges poisonous gas when burning, destroy large natural environment for increasing office chair.
The utility model content:
The purpose of this utility model is to provide at the deficiencies in the prior art a kind of seat back of the body frame of office chair, and the seat back of the body mount structure of this kind office chair is simple, need not use timber, and reduce the use amount of foam significantly, and environmental protection and its cost are low.
For achieving the above object, the utility model is achieved through the following technical solutions: described seat back of the body frame comprises seat frame and two parts of back of the body frame of being made by plastic cement, sit the outside framework of frame and back of the body frame and frame inner frame and all be by two sidewalls and be molded over the plastic plate of the hollow-core construction that two reinforcements between the sidewall constitute, the frame inner frame is horizontal and vertical respectively and is molded in the outside framework, sits at least a in elastic wire and the elastic cord is installed on frame and the back of the body frame.
On the described seat frame elastic wire is installed, the two ends of elastic wire are individually fixed on the outside framework of sitting frame, and elastic wire is crisscross shape.
On the described seat frame elastic cord is installed, the two ends of elastic cord are individually fixed on the outside framework of sitting frame, and elastic cord is crisscross shape.
On the described back of the body frame elastic wire is installed, the two ends of elastic wire are individually fixed on back of the body frame outside framework or the frame inner frame, and elastic wire is crisscross shape.
On the described back of the body frame elastic cord is installed, the two ends of elastic cord are individually fixed on back of the body frame outside framework or the frame inner frame, and elastic cord is crisscross shape.
Described frame inner frame is lower than outside framework.
Protruding upward the arching upward of elastic wire on the described seat frame.
Elastic wire on the described back of the body frame protrudes laterally and arches upward.
Seat back of the body frame of the present utility model comprises seat frame and two parts of back of the body frame of being made by plastic cement, sit the outside framework of frame and back of the body frame and frame inner frame and all be by two sidewalls and be molded over the plastic plate of the hollow-core construction that two reinforcements between the sidewall constitute, sit frame and carry on the back frame elastic wire is installed, at least a in the elastic cord, elastic wire and elastic cord are crisscross, this kind sits frame and back of the body frame adopts plastic cement to make, plastic cement is recyclable to be utilized again, need not use timber, reduce felling to forest, and its structural strength height, the advantage of each side make its seat frame can replacing wood made and back of the body frame; In addition, need not fill foam between elastic wire and seat frame or the back of the body frame, reduce the use amount of foam significantly, environmental protection is free from environmental pollution, in sum, seat back of the body mount structure of the present utility model is simple, the structural strength height need not use timber, and reduces the use amount of foam significantly, environmental protection is free from environmental pollution, and its cost is low.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment sees accompanying drawing 1, and described seat back of the body frame comprises seat frame 8 and 9 two parts of back of the body frame of being made by plastic cement, and the outer ring of sitting frame 8 and back of the body frame 9 is an outside framework 1, and being positioned at the support of sitting frame 8 or back of the body frame 9 and being molded over its back side is frame inner frame 2.Sit the outside framework 1 of frame 8 and back of the body frame 9 and frame inner frame 2 and all be by two sidewalls 4 and be molded over the plastic plate of the hollow-core construction that two reinforcements 5 between the sidewall 4 constitute, the outside framework 1 and the frame inner frame 2 of this kind structure have stronger structural strength, and it is in light weight, and cost is low.
Described frame inner frame 2 is horizontal and vertical respectively and is molded in the outside framework 1, and described frame inner frame 2 is lower than outside framework 1, and when saving materials, frame inner frame 2 increases the structural strength of seat frame 8 and back of the body frame 9, sits frame 8 and carry on the back frame 9 not yielding when pressurized.
On the described seat frame 8 elastic wire 7 is installed, the two ends of elastic wire 7 are individually fixed on the outside framework 1 of sitting frame 8, sit elastic wire 7 protruding upward the arching upward on the frame 8, and elastic wire 7 is crisscross shape, elastic wire 7 forms a supporting surface, need not fill foam between elastic wire 7 and the seat frame 8, reduce the use amount of foam significantly.
On the described seat frame 8 elastic cord 6 is installed, the two ends of elastic cord 6 are individually fixed on the outside framework 1 of sitting frame 8, and elastic cord 6 is crisscross shape, are provided with that elastic cord 6 can increase the elasticity of sitting frame 8, intensity and to the more comfortable sensation of people sitting to install on the frame 8.
