Abstract

The utility model discloses a roof fan hood, which includes a hood frame and a hood body, wherein the hood body is fixed on the hood frame, and the hood body includes two hood end bodies detachably connected. The hood body further includes one or two hood intermediate bodies arranged between the two hood end bodies and detachably connected with the hood end bodies, and the hood intermediate bodies are also detachably connected. The roof fan hood adopts the hood end bodies and the hood intermediate bodies detachably connected, so that hoods of different sizes can be assembled conveniently through the combination of the hood end bodies and the hood intermediate bodies according to different types of fans; and at the same time, the assembly of hoods can be finished on the installation field, so that only the hood end bodies and the hood intermediate bodies are required to be transported, the transportation space is saved, and the transportation cost is reduced.

Description

A kind of roof ventilator blast cap

Technical field

The utility model relates to a kind of parts of blower fan, relates to a kind of blast cap of roof ventilator specifically, belongs to the HVAC field of ventilation.

Background technique

The prior roofs blower fan is made up of pedestal, blower fan and blast cap usually, the blast cap of roof ventilator adopts general steel plate riveted joint or welding fabrication usually, sticky the making of also useful glass fibre reinforced plastic material, because kind, the model of roof ventilator are more, the size of size is also more, cause the size of blast cap also many, the roof ventilator of each kind or model all has the blast cap of specific dimensions basically.Adopt the roof ventilator of prior art, need a large amount of moulds to make the blast cap of all size, caused the raising greatly of manufacture cost, and, if the roof ventilator blast cap of large-size, in transportation, installation process,, make transportation extremely inconvenient, also increased cost of transportation because it has bigger volume.

Summary of the invention

For overcoming above-mentioned defective, the utility model aims to provide the easy disassembly of a kind of energy, can reach a kind of roof ventilator blast cap of performance requirement simultaneously, comprise blast cap frame and cap body, described cap body is fixed on the blast cap frame, and described cap body comprises two cap end bodies, between the described cap end body for removably connecting.

Described roof ventilator blast cap also comprises one or two above cap mesosomes, and described cap mesosome places between two cap end bodies, between described cap mesosome and the cap end body for removably connecting, between the described cap mesosome also for removably connecting.

Removably connecting between described cap mesosome and the cap end body is that the edge cover connects.Neoprene is also posted in connection place between described cap mesosome and the cap end body.Described cap body connect by bolt or riveted fixing on the blast cap frame.

Adopted roof ventilator blast cap of the present utility model, owing to adopted cap end body and the cap mesosome that removably connects, difference according to the blower fan model, can assemble out the blast cap of different size, simultaneously easily by combination to cap end body and several cap mesosomes, because the assembling of blast cap can be finished in the erecting bed, thereby making blast cap is cap end body and cap mesosome when transportation, has saved transportation space, has also saved cost of transportation simultaneously.

Fig. 3 is the structural representation of the cap mesosome in the utility model;

Fig. 4 is the another kind of structural representation of the cap end body in the utility model.

Among the figure: 1-cap body, 2-cap mesosome, 3-cap end body, 4-blast cap frame, 21-cap mesosome end face, body side surface between the 22-cap, 31-cap end body end face, 32-cap end body side surface, 33-blast cap side.

Embodiment

As Fig. 1-shown in Figure 4, the utility model discloses a kind of roof ventilator blast cap, comprise blast cap frame 4 and cap body 1, described cap body 1 is fixed on the blast cap frame 4, described cap body 1 comprises two cap end bodies 3, between the described cap end body 3 for removably connecting.

Roof ventilator blast cap of the present utility model also comprises the cap mesosome 2 more than or two, and described cap mesosome 2 places between two cap end bodies 3, between described cap mesosome 2 and the cap end body 3 for removably connecting, between the described cap mesosome 2 also for removably connecting.

Removably connecting between cap mesosome 2 and the cap end body 3 is that the edge cover connects.

Neoprene is also posted in connection place between cap mesosome 2 and the cap end body 3.

Described cap body 1 connect by bolt or riveted fixing on blast cap frame 4.

Below in conjunction with accompanying drawing roof ventilator blast cap of the present utility model is done more into narration:

Scheme one: shown in Figure 1, blast cap frame 4 and cap body 1, described cap body 1 is fixed on the blast cap frame 4, described cap body 1 comprises two cap end bodies 3, between the described cap end body 3 for removably connecting.As shown in Figure 2, cap end body 3 surrounds a trapezoidal bridge by a cap end body end face 31 and two cap end body side surfaces 32, blast cap side 33 closes the one side of trapezoidal bridge, high in the middle of the cap end body end face 31, two ends are low, the one side that two cap end bodies 3 are not sealed by blast cap side 33 is connected to each other, Placement is that dismountable edge cover connects, in order to guarantee that two joints between the cap end body 3 have rainproof, anti-function of leaking, also need paste neoprene at joint, also can be coated with certainly and else have anti-aging, waterproof materials.

Scheme two: for larger-size roof ventilator blast cap, roof ventilator blast cap of the present utility model also comprises the cap mesosome 2 more than or two, described cap mesosome 2 places between two cap end bodies 3, between described cap mesosome 2 and the cap end body 3 for removably connecting, between the described cap mesosome 2 also for removably connecting.As shown in Figure 3, it is trapezoidal bridge that cap mesosome 2 surrounds a cross section by body side surface 22 between a cap mesosome end face 21 and two caps, and high in the middle of the cap mesosome end face 21, two ends are low.Certainly the cross section of cap mesosome 2 also can be high in the middle of other, that two ends are low form, as circular arc etc.As shown in Figure 4, cap end body 3 can be the blast cap side 33 that shape and cap mesosome 2 cross sections are complementary, as shown in Figure 1, cap mesosome 2 is installed on the blast cap frame 4 successively, and fix with bolt or riveted joint mode, can certainly wait other means of fixation with welding, can dismantle smoothly during for maintenance later on, suggestion adopts bolt or screw mode to fix.Dismountable edge cover that is detachably connected as between removably connecting between cap mesosome 2 and the cap end body 3, the described cap mesosome 2 connects, in order to guarantee between adjacent two cap mesosomes 2 and the joint between cap mesosome 2 and the cap end body 3 has rainproof, anti-function of leaking, also need paste neoprene at joint, also can be coated with certainly and else have anti-aging, waterproof materials.

Scheme one is applicable to the roof ventilator blast cap of reduced size, and scheme two is applicable to the roof ventilator blast cap of large-size, and cap mesosome 2 can be with lathe with color steel or galvanized steel plain sheet is rolling forms, and the size of cap mesosome 2 varies in size according to the roof ventilator model and decides.
