Description

The combined vertical type blast fan

Technical field

The utility model relates to blast fan, refers to the removable flabellum of a kind of employing especially, can significantly dwindle the one injection forming mold, reduces the storage area, the combined vertical type blast fan of being convenient to transport.

Background technique

Commonly using vertical electric fan produces rapidly for reaching, the integrated ejaculation technology of many employings is made, for example: 12 cun vertical electric fan must be twice by the circumferential area than six cun, though be beneficial to integrated making, but, for the size big vertical electric fan of healing, also penetrate production with regard to the larger sized mould of needs, except that the area of production line need strengthen, the space of storage also must increase, especially transportation is more inconvenient, above-mentioned various reasons makes in the past the vertical electric fan of large scale that in addition improved necessity be arranged, therefore, be necessary to research and develop the new structure of flabellum, to solve the shortcoming that it exists.

Summary of the invention

Main purpose of the present utility model is to provide a kind of employing removable flabellum, can significantly dwindle the one injection forming mold, reduces the storage area, the combined vertical type blast fan of being convenient to transport.

A kind of combined vertical type blast fan comprises main shaft part and a plurality of flabellum portion, it is characterized in that:

This main shaft part has a periphery and an axis direction, and this main shaft part is provided with:

An axle bed has a radial part, an inner edge surface and an outer edge surface;

A plurality of caulking grooves are located on this main shaft part periphery along axis direction with intended distance, and indent is between the inside and outside edge face of tube axle bed radial part;

A plurality of first to depend on end corresponding with a plurality of caulking grooves, respectively first depends on the axis direction of end along this main shaft part, is arranged between the inside and outside edge face of an axle bed radial part;

A plurality of second to depend on end corresponding with a plurality of caulking grooves, and each second depends on end and depend on since first and hold, and complies with the trend of each flabellum portion, cuts open between the inside and outside edge face of being located at an axle bed radial part;

Two concave fastening parts along the main shaft part axis direction, are arranged at the both sides of each caulking groove;

A plurality of locking parts are corresponding with a plurality of caulking grooves, and each locking part is arranged at main shaft part near tube axle bed inner edge surface place all along axis direction;

A plurality of flabellum portion is removable, and each flabellum portion is provided with:

At least one flabellum;

One linking department is corresponding with each caulking groove; This bond sites is in the end of flabellum near main shaft part;

Second to depend on end corresponding with each for one locating face, and depends between flabellum and the linking department;

Two convex fastening parts are corresponding with two concave fastening parts, and are formed at the both sides of linking department along axis direction;

One fixing part is corresponding with each locking part, and the vertical central direction is attached on the linking department.

Advantage of the present utility model is as follows:

1, owing to adopts removable flabellum, if vertical fan adopts five flabellum designs of 12 cun, then after taking apart, the size of single flabellum must be less than 12 cun specification, except that the flabellum that is beneficial to littler mould ejection formation same size, also a plurality of flabellums can be carried out modular production, can reduce production costs better.

2, area greatly reduces.The utility model is designed to flabellum removable, if vertical fan adopts five flabellum designs of 12 cun, the area of each flabellum after taking apart, the area that certainty radially distributes less than five flabellums, except that the storage area can significantly reduce, more help transportation, especially, though the utility model is the purpose of creation with vertical fan, also can be widely used in the making of various fan.

Embodiment

Above-mentioned purpose of the present utility model, advantage can obtain to understand in depth from following selected embodiment's detailed description and accompanying drawing, now with the following example and cooperate graphic being described in detail as follows:

Shown in Fig. 1,2, a kind of combined vertical type blast fan comprises a main shaft part 10 and plural flabellum portion 20, wherein:

Main shaft part 10 has a periphery and an axis direction substantially, mainly is provided with:

An axle bed 11 has a radial part, an inner edge surface and an outer edge surface;

A plurality of caulking grooves 12 are located on the periphery of main shaft part 10 along axis direction with intended distance, and indent is between the interior outer edge surface of these axle bed 11 radial part;

A plurality of first depends on end 13, and corresponding a plurality of caulking grooves 12 are provided with, and each first depends on end 13 axis directions generally along this main shaft part 10 and be arranged between the inside and outside edge face of these axle bed 11 radial part;

A plurality of second depends on end 14, and corresponding a plurality of caulking grooves 12 are provided with, and each second depends on end 14 since first end that depends on end 13, according to the trend of each flabellum portion 20, cuts open between the inside and outside edge face that is located at these axle bed 11 radial part;

Two concave fastening parts 15 are located at the both sides of each caulking groove 12 along the axis direction of main shaft part 10;
