The specific embodiment
Below by specific embodiment the utility model is described in further detail.
Be a kind of parallel push type sliding support hinge as depicted in figs. 1 and 2, comprise the first parallel slide rail 1 and second slide rail 2 that are installed on sash and window frame respectively, and the long holder cantilever 6, the weak point that are used to connect on first slide rail 1 and second slide rail 2 hold in the palm cantilever 3 and 7, slide block 8, square shaft 5 and nylon washer 4, one end of long holder cantilever 6 is hinged on first slide rail 1, and the other end and slide block 8 hinged backs are put in the chute of another slide rail 2.One end of a short holder cantilever 7 and the hinged back of another slide block (not shown) put into the long chute that holds in the palm on the first hinged slide rail 1 of cantilever 6 in, one end of another short holder cantilever 3 is hinged on another slide rail 2, two short holder cantilevers 3 then are connected with the middle part of growing holder cantilever 6 by square shaft 5 with 7 the other end, and two short holder cantilevers 3 and 7 are distributed in long holder cantilever, and about in the of 6 both sides, after square shaft 5 passes the circular hole at long holder cantilever 6 middle parts, pierce in the square hole of short holder cantilever 3,7 end anastomosis and be assembled together.Be the circle cover as Fig. 1, Figure 6 and Figure 7 nylon washer 4 middle parts, square shaft 5 middle parts are enclosed within this nylon circle cover, utilize the excircle of this circle cover to cooperate with the circular hole at long holder cantilever 6 middle parts.Because the middle part of long holder cantilever 6 cooperated with cooperating for circular of nylon washer 4, and two short holder cantilevers 3 and 7 with cooperating of nylon washer 4 be square cooperation, thereby two short holder cantilevers 3 and 7 with long holder cantilever 6 between can rotate mutually, then can not move mutually between two short holder cantilevers 3 and 7 and fuse, this X-shaped holder cantilever guarantees parallel the moving between two slide rails 1 and 2, and makes and respectively ask cantilever to overlap fully when the closure with slide rail.
For avoiding long holder cantilever and the wearing and tearing mutually in the switching process of short holder cantilever, between two short holder cantilevers and long holder cantilever, the nylon spacer that is enclosed within on the square shaft 5 is arranged as shown in Figure 1, this nylon spacer can be flat shim independently, also adopt as Fig. 1, Fig. 6 and nylon washer structure shown in Figure 7, i.e. nylon spacer forming by the flange on the nylon jacket.Nylon washer is two, and the nylon circle cover that is enclosed within on the square shaft 5 is formed by two sections, not only be convenient to assemble and also when avoiding adopting individual components because not high interference that causes of machining accuracy and wearing and tearing mutually.The frictional force of nylon washer 4 is little in addition, makes that the unlatching of sash and closure are easier.
Because short holder cantilever the 3, the 7th is hinged with respect to long holder cantilever 6, pin joint is not in same plane, and it is all hinged again with two slide rails 1,2, though can solve the difference in height of different holder cantilevers by increasing pad with the hinged end of slide rail, will certainly increase the integral thickness (being at least the thickness that two slide rail thickness add three holder cantilevers) of whole hinge and reduce the stability of moving with respect to slide rail.Do a preferred embodiment, as Fig. 1 and shown in Figure 5, in the present embodiment long holder cantilever 6 two ends and middle part be bent into successively three grades stepped, two short holder cantilevers 3 (with short holder cantilever 7) then as shown in Figure 1 and Figure 4 accordingly, it is stepped to be bent into the two-stage corresponding with long holder cantilever 6, and at two slide rail middle parts corresponding short holder cantilever is set as shown in Figure 3 and is provided with the breach 9 of stepping down to the part of slide rail direction projection, do not interfere mutually so that respectively ask cantilever to overlap as shown in Figure 1 with slide rail, its thickness is roughly the thickness that two slide rail thickness add two holder cantilevers, helps reducing requisite space when being assemblied on the window.
For what it will be appreciated by those skilled in the art that be, if do not adopt nylon circle cover, cooperate with circular hole and directly be processed into circular shaft with long holder cantilever middle part with regard to axle 5 middle parts, both can be rotated mutually, also be feasible, yet adopt the round cover of nylon can reduce the wearing and tearing of axle and long holder cantilever and the flexibility that raising opens and closes.Based on square shaft 5 is that guarantee between two short holder cantilevers 3,7 can not relative motion, so corresponding pilot hole also can be other non-circular shape on its two ends shape and the short holder cantilever 3,7.
One group of parallel push type sliding support hinge of the utility model is installed on the window, because this sliding support hinge composing type motion, open in the closing course at sliding support hinge between two slide rails 1 that are connected with sash and window frame respectively and 2 and remain parallel motion, and the realization tight closure, can also adopt electronic control or remote control to open and closed sash in addition.
