Detailed description of the invention
Fig. 4 illustrates the exploded view of the fire door structure of the utility model one embodiment.Fig. 5 illustrates the assembly drawing of the fire door structure of the utility model one embodiment.The fire door structure of the present embodiment can be used for micro-wave oven or electric steam furnace, or the household electrical appliance of other similar structures.First with reference to shown in figure 4, fire door structure 20 can comprise outside framework 21, inner frame 22, door-plate 23 and sealing ring 24.These parts are assembled into the structure shown in Fig. 5 successively, and Fig. 5 is the view of inner frame 22 side from fire door structure.Wherein door-plate 23 and sealing ring 24 are assembled in wherein by outside framework 21 and inner frame 22.Outside framework 21 and inner frame 22 can be similar to known framework, also suitable adjustment can be done on this basis, embodiment of the present utility model does not limit the concrete form of outside framework 21 and inner frame 22, as long as they can combine mutually, and door-plate 23 and sealing ring 24 are contained in therebetween.
Door-plate 23 is as wherein one deck of layer door structure.The common material of door-plate 23 is glass.But be appreciated that door-plate 23 can select other transparent or translucent heat proof materials.
Fig. 7 illustrates the structure of the sealing ring of the utility model one embodiment.Fig. 9 illustrates the sealing ring sectional view of the utility model one embodiment.Shown in figure 7 and Fig. 9, sealing ring 24 has the first relative side 24a and the second side 24b.In Fig. 7, left side is the first side 24a, and right side is the second side 24b.As shown in Figure 8, sealing ring 24 has the flange 241 bent towards the first side 24a from its periphery, is used for wrapping up the surrounding of door-plate 23.Flange 241 can be formed continuously along the circumference of sealing ring 24.Flange 241 also can be formed along the circumference of sealing ring 24 discontinuously.As long as flange 241 end of door plate 23 can be allowed to have enough package powers, embodiment of the present utility model does not limit the form that flange 241 distributes in sealing ring 24 circumference.The structure of flange 241 preferably as shown in Figure 8, comprises the Part I 241a that can wrap up door-plate 23 outer rim and the Part II 241b that can wrap up door-plate 23 front surface edge.Sealing ring 24 wraps up the surrounding of door-plate 23 (not shown in Fig. 8) with the inner side 241a of flange 241, thus holds door-plate 23.
After accommodation door-plate 23, sealing ring 24 can be placed on outside framework 21.Figure 11 illustrates the sealing ring of the utility model one embodiment and the assembling schematic diagram of outside framework.With reference to shown in Figure 11, outside framework 21 has the draw-in groove 211 that can hold sealing ring 24.First side 24a of sealing ring 24 framework 21 and snap in draw-in groove 211 toward the outside, and coordinate with draw-in groove 211 with the outside 241c of flange 241.
Fig. 6 is the B-B sectional view of Fig. 5, and it illustrates outside framework 21, inner frame 22, matching relationship between door-plate 23 and sealing ring 24.As shown in Figure 6, after sealing ring 24 snaps in draw-in groove 211, the outside 241c of flange 241 contacts with draw-in groove 211, and the inner side 241d of flange 241 then wraps up door-plate 23.Inner frame 22 pushes down the second side 24b of sealing ring 24, and fixes with outside framework 21, thus forms complete fire door structure.
For example, inner frame 22 can be combined with outside framework 21 by screw 25 as shown in Figure 6.But be appreciated that inner frame 22 also by other structure, such as, need can not be combined with outside framework 21 by the buckle of instrument.
Preferably, as shown in Figure 6, in order to improve sealing ring 24 and the adhesion of inner frame 22, can design towards the projection 42 of the second side 24b at the periphery of sealing ring 24.Between protruding 242 and flange 241, there is depressed part 243, snap in for inner frame 22.
Fig. 8 illustrates the stereochemical structure of the sealing ring of another embodiment of the utility model.Figure 10 illustrates the sealing ring sectional view of another embodiment of the utility model.Shown in figure 8 and Figure 10, in the present embodiment, the periphery of flange 241 is provided with fin 244.Get back to Fig. 6 also with reference to shown in Figure 11, the draw-in groove 211 of outside framework 21 has sidewall 211a and diapire 211b, and fin 244 is for the sidewall 211a interference fit with draw-in groove 211.This interference fit makes not easily to loosen between sealing ring 24 and outside framework 21.
The fire door structure of the utility model above-described embodiment, settles door-plate by sealing ring, can cancel silica gel, thus saves the silica gel time of repose originally needing to paste door-plate, and saves installation cost.In addition, door-plate can take off and change separately from sealing ring, improves the convenience of maintenance.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
