Abstract

An air diffuser is disclosed comprising a body part (1) with an air flow channel passing there through and a brace (2) for supporting a flow control disc, the brace having an elongated shape extending across the cross section of the flow channel and the brace (2) being made from the same material blank as the body part (1) and the center point of the brace having an inner-threaded hole (3) made thereon to accommodate the center shaft of the flow control disc. The invention is implemented such that the brace (2) is bent into a substantially U-shaped cross section and the flanges of the brace cross section are affixed to each other at least at one point about either side of the brace center hole (3).

Description

Air diffuser

Technical field

The present invention relates to a kind of air diffuser, this air diffuser comprises having main part that runs through air duct wherein and the support member that supports the air-flow control panel, this support member has the shape of the elongated of the cross section extension of striding air duct, and this support member made by the former material base identical with main part, is formed with internal thread hole to hold the central shaft of air-flow control panel at the central point of this support member.

Background technology

Air diffuser may be inlet air diffuser or the evacuating air diffuser on room wall or on the ceiling to be installed.Air diffuser body divides this term to refer to a kind of final element, and it is designed to can be installed on the end of circulation of air pipeline, and has the support member that is used on this diffuser usually with adjustable mode attaching air-flow control panel.This support member is to stride the parts that air duct extends and locate at the center point to have usually internal thread hole, and the central shaft with corresponding externally threaded control panel rotates in this internal thread hole.

Generally speaking, support member is attached on this main part by support member is welded on the diffuser body part at two place, end.Because support member must support the diffuser air flow control panel that is positioned at its screwed hole, therefore, support member should have the required enough rigidity of this kind function.General this support members separated is by making than the thicker material of diffuser body part.Yet support members separated needs extra operation just can be installed on the main part.

According to prior art, the diffuser with support member of being made by the former material base identical with main part also is known.Wherein, the sufficiently high rigidity of this support member is by replacing traditional two legs to be protected with three radial legs in the design of support member.Yet this support member is difficult to make, and in addition, the extra leg of support member can hinder air and flow through diffuser, also can increase tedious noise simultaneously.

Summary of the invention

The purpose of this invention is to provide a kind of have use with diffuser body the air diffuser that divides support member that identical former material base makes, can also overcome the deficiencies in the prior art simultaneously.

For realizing this purpose, the present invention is a kind of air diffuser, comprise main part and the support member that is used for supporting the air-flow control panel, this main part has the air duct that runs through wherein, described support member has the shape of the elongated of the cross section extension of striding air duct, and support member is made by the former material base identical with main part, central point at support member is formed with internal thread hole to hold the central shaft of air-flow control panel, it is characterized in that: described support member is bent to the cross section that roughly takes the shape of the letter U, and the edge of a wing of support member cross section interconnects on a point at least in the both sides of support member centre bore.

First preferred embodiment of the invention is characterised in that the edge of a wing of the cross section of support member interconnects by welding.

Second preferred embodiment of the invention is characterised in that the edge of a wing of the cross section of support member interconnects by riveted joint.

Third preferred embodiment of the invention is characterised in that the edge of a wing of the cross section of support member interconnects by the crimping technology.

Four preferred embodiment of the invention is characterised in that the edge of a wing of support member comprises protuberance, and the edge interconnects at the protuberance place.

Therefore, basic thought of the present invention is that from dividing identical former material base to make support member with diffuser body, the thickness of its material is very thin for traditional design.The edge of a wing of support member cross section interconnects on two points at least, thereby has fully increased the rigidity of support member.This has outstanding beneficial effect on the large-scale air diffuser.If the edge of a wing of support member cross section does not interconnect, support member does not just have sufficient rigidity with the support diffuser control panel so.

Description of drawings

Below, will further be described in detail in conjunction with the accompanying drawings the present invention.Wherein:

Fig. 1 shows that air diffuser body is divided and the axonometric drawing of support member in an operation, wherein the cross sectional curve of the support member shape that becomes to take the shape of the letter U substantially;

Fig. 2 shows the top view of assembly shown in Figure 1;

Fig. 3 shows the side view of Figure 1 and Figure 2 assembly;

Fig. 4 shows according to air diffuser body of the present invention and divides and the axonometric drawing of support member in an operation, and wherein locate to be connected to each other at 2 in the edge of a wing of support member cross section; And

Fig. 5 shows the top view of assembly shown in Figure 4.

The specific embodiment

According to Fig. 1-3, show air diffuser body and divide 1 with support member 2.Support member has the shape of the elongated that the cross section of the air duct of striding diffuser extends.This support member is connected on the main part at the edge of air duct.Support member is made by the former material base identical with main part, so the main part unnecessary portions is at first cut, and then the support member material that overlaps with air duct partly is bent to final shape.In the operation of Fig. 1-3, the cross section of support member is bent to roughly U-shaped.Central point at support member is made common internal thread hole 3, with thread spindle (not shown) rotation of holding the air-flow control panel, thereby can control diffuser by rotating control panel.

Reference numeral 4 refers to the protuberance of making on the support member edge of a wing, and this protuberance makes the edge of a wing of support member to link together with Fig. 4 and mode shown in Figure 5.In design as shown in the figure, respectively be provided with two protuberances on two edges of a wing of support member, each side of the centre bore 3 on the edge of a wing is provided with a protuberance.Described protuberance can be by being connected to each other such as welding, riveted joint or employing crimping (crimping) technology.Yet any other interconnection technique that is equal to can be used.Protuberance connection each other makes the twisting resistance lower support that support member has bigger rigidity and can apply at control panel.

For those skilled in the art, clearly, the present invention is not limited by above-described embodiment, on the contrary, can change in spirit of the present invention He in the claim protection domain.Therefore, the tie point on the edge of a wing of support member can perhaps also can be selected this edge of a wing is interconnected on whole length more than two.The protuberance that is provided with on this edge of a wing also can be omitted, especially on bigger support member.
