Abstract

The utility model relates to an improved structure of a minitype or small-sized cooling blower frame, which comprises a frame part (1) and a motor matching part (2). A supporting seat (3) arranged in the frame part (1) is integrally connected with the frame part (1) via supporting legs (4); the frame part (1), the supporting seat (3) and the supporting legs (4) are made of plastics, and the motor maching part (2) is made of metal; the motor maching part (2) is fixed in the trough of the supporting seat (3) by the method of plastic injection, and a wire groove (5) is arranged on at least one supporting leg (4) and communicated with the supporting seat (3). The maintenance of the frame of the utility model is convenient, and compared with a full metal frame, the cost is relatively low. Moreover, if the motor matching part is firmly connected with the supporting seat by applying screw bolts, no matter whether the motor matching part or the frame part is damaged, only the damaged part needs to be replaced, thus avoiding the waste caused by discarding the whole machine.

Description

The structure-improved of miniature or small-sized cooling air frame

Technical field

The utility model relates to a kind of structure-improved of cooling air frame, especially a kind of structure-improved that comprises the miniature or small-sized cooling air frame of frame and motor counterpart.

Background technique

Common on the market miniature or small-sized cooling air frame generally is made of one structure with motor counterpart and frame.The frame of this structure in fact, on production technology, increased difficulty for housing, when injection moulding or die casting, cause the housing distortion easily, so disqualification rate height of product component, and overall plastic its heat resistance of glue frame is relatively poor, service time is long slightly, and the heat that produces that runs up of motor might make the local deliquescing of plastic cement frame; Moreover this motor counterpart and frame are made integral body, and the selection of material is more single with use, are unfavorable for carrying out the product cost allotment; In addition, just say in the maintenance that this structure still be all inconveniences or cause waste of user to manufacturer.Such as broken down a bearing, motor supporting position or newel, for manufacturer, the whole wind frame has just been scrapped, and whole blower fan is scrapped for the user, causes bigger waste.

Summary of the invention

The purpose of this utility model is the structure-improved that the miniature or small-sized cooling air frame that a kind of cost is cheap relatively, heat resistance is better, easy to maintenance relatively is provided to society.

The technical solution of the utility model is: at above-mentioned structural imperfection, the utility model is divided into frame and motor counterpart with frame and motor counterpart design mix body structure, is provided with wire casing on the support of framework, to make things convenient for cabling.Handle like this, more stable than overall structure with regard to single part die casting or Shooting Technique moulding, the distortion reject ratio is low; From both assembly technology aspects, it is more that technological method is selected, the different fit systems of two parts of design, can choose that screw is fastening, injection moulding, gluing, screw is riveted tightly, interference is press-fitted or ultrasonic weld etc.; Going up from the selection collocation of material, can require to select neatly both material collocation according to the Environmental Conditions of blower fan, is plastic cement as housing, and the motor counterpart is cast aluminium or casting zinc etc., so also helps reducing the cost of product; And be convenient to maintenance, renewal part has been gone bad a part and has been unlikely to complete machine and scraps and cause waste.

Specifically, the utility model is a kind of structure-improved of miniature or small-sized cooling air frame, comprise frame and motor counterpart, in described frame, be provided with supporting base, described supporting base is connected as a single entity by supporting foot and described frame, described frame, supporting base, supporting foot are plastics, and form by the injection moulding mode and to be one; Described motor counterpart is a metal, and the motor counterpart is fixedly installed in the described supporting base.

The inner ring of described frame is circular, and its outer ring can be circle, oblateness or square.

Described frame is seen on the whole and is pancake.

Described motor counterpart is fastening by screw, injection moulding, gluing, screw is riveted tightly, interference is press-fitted or ultrasonic welding is fixedly installed in the described supporting base.

Described supporting foot is vertical with described supporting base outer wall or tangentially is connected.

Described wherein at least one supporting foot is provided with wire casing.

The utility model is a working of plastics owing to having adopted frame, and the motor counterpart adopts the structure of metalwork, this sample frame have easy to maintenance in, for the full-metallic frame, cost is cheap relatively, simultaneously, when motor counterpart and supporting base adopt screw to be fastenedly connected, no matter be the motor counterpart, still frame damage, all only need to change its damaged part, be unlikely to complete machine and scrap and cause waste.
