Abstract
The present invention relates to a connection type fan. A plurality of blades are formed into a cylindrical plastic fan by boards at both sides, wherein a plurality of protruding pins are arranged on a board at one side, protruding pin insertion holes for inserting other fans connected with the protruding pin insertion holes are arranged on a board at the other side, a fan single body is formed, which is then connected with fan single bodies of a needed number, side boards with protruding pin insertion holes and supporting shafts are inserted in and connected with the board at one side of the fan after connection, side boards with protruding pins and rotary shafts are inserted in and connected with the board of the other side, and a needed integral fan is formed.
Description
The present invention relates to a kind of jointing type cross flow fan that can extensively be installed in duplicating machine, air-conditioner and other office equipment.
The air-supply that has earlier has been widely used on duplicating machine, air-conditioner and other office equipment with in order to the cooling machine with cross flow fan, and applied fan is normally metal on these machines, and has and meet the required length of machine.Though the fan of certain length can be applicable to multiple machine, be used on the significantly different machine of air quantity, just must be required by various machines, design meets the cross flow fan of various machine lengths respectively, and this is very uneconomic.Also can consider to prepare the cross flow fan that multiple different length is different fan amplitudes, but there is the problem of whether having utilized the fan amplitude well in this method, its differences is big resolutely, and it is very uneconomic getting all fans ready.
Therefore,, need to increase the fan length of same diameter,, promptly with ring frame the two boards of joint is tightened up and couple together from the outside sometimes just with the combination of fans connection for obtaining necessary air quantity.But this method can produce the shortcoming that needs to increase external diameter because of ring frame, can not make the fan miniaturization, and it is not normal thereby produce shortcoming such as noise to occur joint when high speed rotating.Also having a kind of is the scheme of improving the shortcoming of above-mentioned jointing type cross flow fan, i.e. plastic jointing type cross flow fan shown in the EPO246325A1.But the problem of this jointing type cross flow fan is the joint complex structure, is unfavorable for reducing cost.
Therefore, the objective of the invention is to overcome the above-mentioned defective of prior art and a kind of jointing type cross flow fan is provided, promptly produce certain-length in batches and the identical plastic fan of diameter, the fan that connects these certain-lengths with simple connection method, make it meet the size of using machine, can obtain the cross flow fan of Len req easily, i.e. the jointing type cross flow fan.
Be a kind of jointing type cross flow fan of realizing that purpose of the present invention proposes, its impeller is the integral wheel that is connected into Len req by a plurality of cylindric plastic fan monomers and two supports spare, described fan monomer is made up of a plurality of blades and both sides blade link, one in the blade link of described both sides is the plate of the prominent pin of band, another is the plate of band patchhole, a plate for prominent pin of band and running shaft in the described two supports spare, another is the plate of band patchhole and supporting axle.
The description of drawings of the embodiment of the invention is as follows:
Fig. 1 is the front view of jointing type cross flow fan;
Fig. 2 is the fan monomer front view, and has part to analyse and observe;
Fig. 3 is the side view of fan shown in Figure 2;
Fig. 4 is the sectional view of the side plate of that side relative with motor-side is installed;
Fig. 5 is the side view that has the side plate of motor-side running shaft;
Fig. 6 is the example explanatory drawing of prominent pin of expression and the patchhole relation of combining;
Fig. 7 is the same with Fig. 2, is the front view of an expression fan monomer part;
Fig. 8 is the same with Fig. 3, is the side view of an expression fan monomer part;
Fig. 9 is the same with Fig. 6, is the schematic illustration of prominent pin of expression and the patchhole relation of combining.
From the above mentioned, example explanation the present invention with regard to Fig. 1 and Fig. 2, on the columnar fan monomer A that constitutes by a plurality of blades (1), the outside of the plate (2) in two boards (2), (2) is provided with a plurality of prominent pins (3), as shown in Figure 2, and on another piece plate (2), be provided with circular pin hole (4) (consulting Fig. 3), these holes (4) are used for inserting the prominent pin that is oppositely arranged on other fan monomer plate that is connected on the plate (2), also be provided with another fan monomer A, connect this fan monomer A, just become the fan that connects as one shown in Figure 1.On the plate in back (2) side plate (6) is housed, patchhole (4) and supporting axle 5(that this side plate has prominent pin (3) consult Fig. 4), and side plate (8) is housed on another piece plate (2 '), this side plate has prominent pin (3) and the running shaft (7) (consulting Fig. 6) in the patchhole, this biside plate is combined can constitute the jointing type cross flow fan.Also have, Fig. 6 is the prominent pin (3) on display plate (2) and the side plate (8) and the enlarged view of the relation between the through hole (4) on plate (2) and the side plate (6), is to engage prominent reliably one of the example of shape of selling.
Also have, Fig. 7, Fig. 8 represent the connection method different with Fig. 2, Fig. 3, promptly dashing forward between patchhole of selling in order to insert and to connect this on plate (2) of prominent pin on the plate (2) and another side, come to connect design with other.Prominent pin (3) among Fig. 7, its termination are semicircle, and the hole (4) that this semicircle head process pin (3) inserts the with groove of the fan monomer A that is connected connects, and its Placement is here to rotate slightly and can fix to groove again after inserting.
As mentioned above, the present invention can couple together a plurality of fan monomer A as required simply and easily with the integral type fan that the replacement of jointing type cross flow fan has earlier, obtains being suitable for the jointing type cross flow fan of various machine installation specifications; Its structure just is provided with prominent pin in a side that constitutes blade side plate cylindraceous, be provided with in order to insert the patchhole of prominent pin at the fan monomer A opposite side relative with it, and the side plate (8) of the side plate (6) of the band supporting axle that links to each other with both sides and installation running shaft assembles, just can be as mentioned above, type according to machine provides needed air quantity, particularly joint is not prominent outside, so outward appearance is good.In addition, joint can be not normal yet during high speed rotating, so noise is little.This shows that jointing type cross flow fan of the present invention is a kind of manufacturing and uses the very reasonable and very good fan with excellent results.
