The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Need explanation, all directionality instruction (such as up, down, left, right, before and afters in the utility model embodiment ...) only for explaining the relative position relation, motion conditions etc. under a certain particular pose (as shown in drawings) between each parts, if when this particular pose changes, then directionality instruction also correspondingly changes thereupon.
In addition; technical scheme between each embodiment can be combined with each other; but must be can be embodied as basis with those of ordinary skill in the art; when technical scheme combination occur conflicting maybe cannot realize time will be understood that the combination of this technical scheme does not exist, also not the utility model require protection domain within.
The utility model proposes a kind of spiral case assembly and a kind of smoke exhaust ventilator with this spiral case assembly.
Referring to figs. 1 through Fig. 3, in the utility model one embodiment, this smoke exhaust ventilator comprises cabinet 10 and the electric-controlled box (not shown) be located in cabinet 10 and spiral case assembly; This spiral case assembly comprises spiral case 20 and interval and is located at many wrapping posts 30 on spiral case 20.Electric-controlled box is installed on spiral case 20, from electric-controlled box turnover connection wire 40 (Fig. 1 to Fig. 3 does not have the label of 40) successively bending be wound in this many wrapping posts 30, and by the frictional force formed between described connection wire 40 outer surface with described wrapping post 30 outer surface realize described be connected wire 40 outside electric-controlled box fixing.So, the technical scheme of described connection wire 40 is pressed solidly compared to the wire pressing block fixed by screw, the technical program only needs described connection wire 40 successively bending to be wound on described many wrapping posts 30, make the fixed installation process of connection wire 40 on spiral case 20 passing in and out described electric-controlled box comparatively simple, in addition, can save the element that wire pressing block and screw etc. are extra, cost is lower.
In the present embodiment, described wrapping post 30 is provided with three; Certainly, in other embodiments, the quantity of described wrapping post also can be set to two, four, five etc., and the design is not restricted this.In the present embodiment, the cross section perpendicular to its length bearing of trend of described wrapping post 30 is square, and namely described wrapping post 30 is square column; Certainly, in other embodiments, described wrapping post 30 also can but be not limited to cylinder, triangular prism etc., the design is not restricted this.
With reference to Fig. 2, in the present embodiment, the preferred setting that forms a line at equal intervals of described many wrapping posts 30, is fastened with the continuous indifference realizing described connection wire 40.Certainly, in other embodiments, described many wrapping posts 30 also can be arranged by interval Heterogeneous Permutation, so, can complete being fastened (with reference to Fig. 4) of described connection wire 40 in less space.
With reference to Fig. 2, in the present embodiment, described wrapping post 30 preferably and spiral case 20 integrated injection molding.Shooting Technique is ripe processing technology, is convenient to the processing of the spiral case 20 with described wrapping post 30.Preferably, described wrapping post 30 is arranged in hollow, to save the use of injection moulding sizing material.In the present embodiment, the injected plastics material that this spiral case 20 integrated injection molding adopts can be, but not limited to as PP (Polypropylene, polypropylene), ABS (AcrylonitrileButadieneStyreneplastic, ABS plastic), PVC (Polyvinylchloride, polyvinyl chloride) or PC (Polycarbonate, Merlon) etc.
It is emphasized that, in other embodiments of the present utility model, described wrapping post 30 can also be connected to spiral case 20 by the mode removably connected, so, once the phenomenon of fracture or heavy wear has appearred in arbitrary wrapping post 30, can be disassembled and changed.Particularly, described wrapping post 30 is preferably provided with the end of thread be connected with spiral case 20, and spiral case 20 is correspondingly provided with the screwed hole screwed in for end of thread adaptation, to realize being spirally connected of described wrapping post 30 and described spiral case 20.Right the design is not limited thereto, and described wrapping post 30 is also connected to described spiral case 20 by the connected mode of snapping etc.
With reference to the close-up schematic view that Fig. 5, Fig. 5 are the utility model smoke exhaust ventilator embodiment again.The difference of the present embodiment and previous embodiment is only, the outer surface of described wrapping post 30 is provided with anti-skid structure 50, to strengthen the frictional force between described connection wire 40 and the wrapping post 30 be wound, and improve described connection wire 40 and twine the fixing reliability be fixed on described many wrapping posts 30.In the present embodiment, described anti-skid structure 50 is preferably anti-skidding salient point layer; Certainly, in other embodiments, described anti-skid structure 50 also can but be not limited to anti-skidding concave point layer or anti-slip veins etc.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every under inventive concept of the present utility model; utilize the equivalent structure transformation that the utility model description and accompanying drawing content are done, or directly/be indirectly used in other relevant technical fields to include in scope of patent protection of the present utility model.
