Background technology

The place of taking about the chair tool, backrest or headrest place, all being provided with can be for the supporting surface of supporting human body, and this supporting surface is except the sofa pad of entity, also have as supporting surface with dictyosome, though the material of this dictyosome has excellent toughness, ability is lived long-term compressing and can elastic fatigue and distortion, and with good result of ventilating heat dissipation, and this dictyosome normally is fixed between two frameworks by clamping, its structure such as Fig. 1,2 and shown in Figure 3, promptly a main frame 1 (is a cushion, the main framework of backrest or headrest) is provided with the recessed portion 11 of closing along the middle book office of its framework, and is provided with a plurality of fixing holes that run through 12 along recessed place, bottom of closing portion 11; In addition, above corresponding to main frame 1, establish a screen frame 2, and on corresponding to the recessed screen frame 2 that closes portion 11, then be provided with the protruding portion 21 of closing, the recessed portion 11 of closing can be coincide mutually with the protruding portion 21 of closing.

Therefore, after will being laid on the screen frame 2 as the dictyosome 3 of supporting surface, make after downwards, inwardly folding again of this dictyosome 3 all around, and make and be subjected to straining at of predetermined tension, allow the wire side of dictyosome 3 form the supporting surface of predetermined tension, and then the edge of dictyosome 3 is solid on the screen frame 2, and then the screen frame 2 that nail is covered with dictyosome 3 is placed the top of main frame 1, and make both protruding close portion 21 with recessed close portion 11 chimeric after, pass each fixing hole 12 by each screw 4 again, and then screen frame 2 be locked on the main frame 1, also allow simultaneously dictyosome 3 by clamping between main frame 1 and screen frame 2, and each screw 4 is again when passing dictyosome 3, and dictyosome 3 blockings are lived.

Though dictyosome 3 is fixed by main frame 1 and screen frame 2 clampings, but when dictyosome 3 supporting surfaces are subjected to the compressing of weight, the phenomenon of slippage still can take place in dictyosome 3 between main frame 1 and screen frame 2, so screw 4 everywhere promptly can stop the slippage of dictyosome 3, but because screw 4 everywhere is the drawing effect of point-like on dictyosome 3, allow pullling that each screw 4 place of dictyosome 3 are concentrated, cause this mesh everywhere to enlarge on the contrary, lax phenomenon takes place in the dictyosome 3 that makes former instinct have predetermined tension.

Simultaneously, owing to have certain distance between each two adjacent screw 4, so when dictyosome 3 supporting surfaces are subjected to the compressing of weight, because being subjected to the drawing of screw 4, the dictyosome 3 at this place do not stop, and then can be solid in screen frame 2 parts to dictyosome 3 nails, produce powerful effect of pullling, but because dictyosome 3 itself is promptly for to be woven the cellular dictyosome that forms by the line body, edge after its cutting is bound to produce irregular lax shape, and dictyosome 3 is by the solid place at screen frame 2 of nail, promptly very near this edge, therefore after the nail of dictyosome 3 is in admittedly and is subjected to powerful pullling, very easy phenomenon of unclamping not only causes the lax of dictyosome 3, more can cause taking off of dictyosome 3 when serious.

So the combination between above-mentioned dictyosome 3 and screen frame 2, the main frame 1 can't allow dictyosome 3 bear the compressing of weight for a long time and shortens life-span of its use.

The utility model content

For improve combine fixing mode between aforementioned existing dictyosome and screen frame, the main frame can't be firm and the lax problem that comes off arranged, the utility model provide a kind of be installed with around the dictyosome can by clamping in main frame and screen frame recessed close portion and protruding close between the portion around the line body, the pulling force that allows the dictyosome edge be born can be evenly distributed, and more can prevent the lax and slippage of dictyosome simultaneously.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of dictyosome of chair tool supporting surface and the combined structure of framework comprise that a dictyosome is fixed on the screen frame, is locked in screen frame on the main frame, wherein again:

Neighboring edge place seam around this dictyosome if be coated and fixed a circle around the line body;

Be equipped with the protruding portion of closing of convex around this screen frame bottom, and dictyosome is laid on to make on the screen frame to fold into around the dictyosome to envelope and protrudingly closes after the portion by nail is solid, the line body of dictyosome winding just in time corresponding to protruding close in the portion along around;

This main frame end face is provided with can be for the protruding chimeric recessed portion of closing of portion of closing of screen frame, and then when screen frame is locked on the main frame with each screw, this line body place just in time is sandwiched in protruding close portion and recessed closing between the portion, and Suo Gu solid screw also just in time is positioned at the outer side edges place of line body simultaneously.

In the such scheme, this dictyosome edge seam is established the cloth body of a covering thread body, and the neighboring edge place is solid on the screen frame around making the cloth body.
