Description
Technical field
The invention belongs to chair technology field more particularly to a kind of chair back frames.
Background technique
Chair is a kind of daily life furniture, and one kind having backrest, also armed thing to sit on.
Its structure of backrest generally comprises outline border, and the inner support member being connected in outline border.
And the outline border made of plastic cement, can have extraordinary elastic property, elastic property its can be in order to mentioning
For preferable comfort.
Existing plastic cement outline border, has following defects that
After its receiving back extruding force of outline border, it will can not effectively disperse the progress of extruding force outline border, lead to chair
Comfort it is poor.
Summary of the invention
Regarding the issue above, the present invention provides a kind of can be improved elastic property and the more practical chair back
Frame.
In order to achieve the above objectives, present invention employs following technical proposals: this chair back frame includes made of plastic material
Rectangular box, is respectively equipped with side card slot one on the two sides lateral surface of rectangular box and the side card slot one is by rectangle
The two sides of framework cut into preceding card-tight part and rear card-tight part, and card-tight part and/or rear card-tight part are equipped with several in each of front
Every the relief groove for being arranged and being connected to the side card slot one.
Elastic deformation performance in a thickness direction can be improved in the side card slot one of design, can be effectively to pressure
Power is dispersed.
The relief groove of design can reduce partial cross section's thickness of rectangular box side, can be carried out with shape paired pressure
Dispersion, greatly improved elastic property and comfort, can prolong the service life and improve practicability.
Side card slot one cooperates with relief groove, and total design is more reasonable.
The decompression slot number being disposed therein on a preceding card-tight part in above-mentioned chair back frame and setting are at another
Decompression slot number on preceding card-tight part is equal.
Quantity is equal, can be in order to the exploitation of mold, and reduces manufacturing cost, at the same time it can also improve production effect
Rate.
In above-mentioned chair back frame, relief groove and the setting being disposed therein on a preceding card-tight part block before another
Relief groove in tight portion is arranged in a one-to-one correspondence.
The structure its can be in order to improving the elastic symmetry and production efficiency of structure.
In above-mentioned chair back frame, the two sides of rectangular box respectively include arching lumbar support portion and straight back-supported
Portion, side card slot one are arranged on the lateral surface of the flat back support portion and arching lumbar support portion, and relief groove setting exists
On the preceding card-tight part of flat back support portion.
When people is sitting on chair, chair back lower part is using the convex surface outermost point of arching lumbar support portion as fulcrum, when pressed
The top waist movement that elasticity can be generated, reaches the function of waist support.
In above-mentioned chair back frame, fixing seat, two fixations are connected separately in the middle part of the rectangular box two sides inner wall
Seat is symmetrical set.
Fixing seat its be convenient for connecting with neck by two connecting fulcrums of frame.
In above-mentioned chair back frame, the rectangular box two sides and downside inner wall are connected separately with convex and reinforce edge,
The back side that convex reinforces edge is arranged in the fixing seat, reinforces setting between edge and the two sides inner wall of rectangular box in convex
There are reinforcement convex ribs, a reinforcement convex ribs are distributed on the outside of each fixing seat, reinforces height of the convex ribs to rectangular box inner bulge
Degree is equal to height of the fixing seat to rectangular box inner bulge.
Convex reinforces the design at edge, and whole structural strength can be improved.
Convex reinforces the front at edge and forms ring-shaped step with the inner wall of rectangular box, and convex reinforces the back side and the square at edge
The back side of shape framework flushes.
The design for reinforcing convex ribs, may insure the structural strength at connecting fulcrum, avoids seeing cracking phenomena.
The equal structure of height of projection, can it is easy to process and manufacture, simultaneously, it is thus also avoided that subsequent removably to interfere.
In above-mentioned chair back frame, the convex for being connected to rectangular box two sides inner wall reinforces convex height of the edge in the middle part of it
Greater than the convex height that convex reinforces edge both ends, the middle part that convex reinforces edge is arranged in the fixing seat, and described adds
The middle part that convex reinforces edge is arranged in strong convex ribs.
It can be further improved structural strength to the structure, and prolong the service life.
Outer side edges are equipped in above-mentioned chair back frame, on the downside of the rectangular box is connected to the side card slot one
Side card slot two.
The side card slot one and side card slot two of design can be caught in fixation in order to the periphery of backrest, can substantially mention
The intensity of high structure, and prolong the service life, at the same time it can also further increase disassembly efficiency.
In above-mentioned chair back frame, the rectangular box upper inside walls are connected with rear convex arch block, rear convex arch block
Both ends are connected to convex and reinforce on the two sides back side at edge, are equipped with attachment base in the positive Middle face of rear convex arch block.
The design of convex arch block afterwards can be improved in anti-deformation intensity and the width direction at the top of rectangular box
Booster action, meanwhile, it is also convenient for the assembly and connection of subsequent parts.
In above-mentioned chair back frame, it is equipped between the rear convex arch block both ends and the two sides back side at convex reinforcement edge
Triangle joint block is respectively equipped with several through-holes one on each triangle joint block, convex reinforce edge on be equipped with it is described
The through-hole two that through-hole one is connected to one by one is equipped with the through-hole three being connected to one by one with the through-hole one on rear convex arch block；
The through-hole one, two and three of design, can be in order to the fixation of backrest.
Also there is the bottom hole of several non-circular blind holes and non-circular blind hole in the position that convex reinforcement edge is equipped with through-hole two
It extends in triangle joint block；
Non-circular blind hole includes trapezoidal hole, any one in tri-angle-holed and slotted eye.
The top side risen there are two the rear convex deep gouge for being located at connection seat both sides, rear convexo-convex and square are set in the front of rear convex arch block
The top side of shape framework flushes, and the back side of remaining side and rear convex arch block that rear convexo-convex rises forms step, on rear convex arch block
Equipped with several along the rear spaced through-hole four in convex arch block length direction, and the rear end of through-hole four is connected to step, through-hole
Three are connected to step.
The design of convex deep gouge afterwards can save material, at the same time it can also improve structural strength.
Through-hole four its fixed convenient for the top margin of backrest.
Compared with prior art, it is the advantages of this chair back frame:
1, the side card slot one designed, can be improved elastic deformation performance in a thickness direction, can be effectively right
Pressure is dispersed.
2, design relief groove, partial cross section's thickness of rectangular box side can be reduced, can with shape paired pressure into
Row dispersion, greatly improved elastic property and comfort, can prolong the service life and improve practicability.
Side card slot one cooperates with relief groove, and total design is more reasonable.
3, structure is simple and easy to manufacture.
