The specific embodiment:

Please refer to Fig. 1 to shown in Figure 5, it has demonstrated the concrete structure of the preferred embodiment of the utility model, include main frame 10, fit framework 20 and dictyosome 30, the periphery of this dictyosome 30 and fit framework 20 are affixed and be installed on the fit framework 20, the fit framework 20 that is equiped with dictyosome 30 further is assembled on the main frame 10, makes the formation one of combination back be supported and be provided by dictyosome 30 Chair back of ventilative comfortableness by main frame 10.

Particularly, as Fig. 3, this main frame 10 is to be made by the plastic material injection mo(u)lding with certain intensity, and surrounds the square framework that forms a hollow by left and right two vertical plate 101,102 and upper and lower two transverse plates 103,104, maintains body mechanics's arc curve.This main frame 10 is used to be assembled in seat, as the main support of backrest.Particularly, front surface in left and right vertical plate 101,102 and following transverse plate 104 is provided with a detent that takes the shape of the letter U 11, what be respectively arranged with in the detent 11 on left and right vertical plate 101,102 simultaneously that two spacings distribute colludes groove 12, be respectively arranged with the screw column 13 that two spacings distribute in the detent 11 on following transverse plate 104, wherein this to collude groove 12 preferably be the structure that opening makes progress.

As Fig. 4,20 same systems of this fit framework are made by the plastic material injection mo(u)lding with certain intensity, and surround the square framework that forms a hollow by left and right two vertical plate 201,202 and upper and lower two transverse plates 203,204, maintain body mechanics's arc curve.

This fit framework 20 is suitable with the size of aforementioned main frame 10, the left and right sides vertical plate 201,202 of fit framework 20 and following transverse plate 204 correspondences are flush-mounted in the U-shaped detent 11 of aforementioned main frame 10, and in the left and right vertical plate 201,202 of fit framework 20 on the back side of main frame 10 respectively spacing be provided with two hooks 40, spacing is provided with two-screw hole 21 on 20 times transverse plates 203 of fit framework; This is linked up with 40 corresponding snap closes and colludes in the groove 12 in aforementioned, and two-screw hole 21 lock onto on the screw column 13 after aforementioned two-screw post 13, two screws then pass this screw hole 21.Wherein, this hook 40 preferably is a hardware, and by screw locking on fit framework 20 (as Fig. 5).

The concrete assembling process of present embodiment is, at first needs dictyosome 30 is fitted on the fit framework 20, then four hooks 40 is loaded on the fit framework 20 by set screws, just begins to assemble fit framework 20 and main frame 40 then.When assembling fit framework 20 and main frame 10, it is the fit framework 20 that tilts slightly earlier, make four hook 40 complete corresponding snap closes after four are colluded in the groove 12, again screw hole 21 correspondences are set on the screw column 13, on this screw hole 13, screw in screw at last, fit framework 20 can be installed on the main frame 10 securely.

Certainly, hook 40 in the previous embodiment not only is confined to four with the quantity of colluding groove 12, the quantity of screw hole 21 and screw column 13 also not only is confined to two, and it also can be provided with corresponding more or less quantity according to the needs of product practical structures size and intensity, not to exceed.

Design focal point of the present utility model is, it mainly is a kind of improvement of package assembly between the fit framework of Chair back skeleton and the main frame, its connected mode that combines with screw by hook has replaced the pure screw locking ways of connecting of tradition, compare, not only make the dismounting operation of fit framework and main frame more simple,, and can improve the production and assembly efficient of product greatly with dismounting and the maintenance that is convenient for people to, and then reduce production costs, finally promote its market competitiveness.

The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
