Description

Foldable fan

Technical field

The utility model relates to a kind of Hand swing fan, and particularly a kind of hand folding is fanned.

Background technology

Hand swing fan generally includes not folding single page fan, folding Foldable fan.

Single page fan is most commonly in PP Advertising fan, and comprise single fan blade, O handle or staight shank, handle is connected with flabellum.The Chinese patent patent No. 201420295241.9, day for announcing 2014.11.05, title " single page fan ", this utility model discloses a kind of single page fan, also comprise flabellum longitudinal axis support portion, arrange along the flabellum longitudinal axis, connect fan handle, flabellum simultaneously, so can reduce flabellum thickness, thus reduce whole fan cost.

Foldable fan is modal is fan-shaped folding fan, and comprise flabellum, one group of ribs of the fan that fan-shaped organ is folding, the ribs of the fan first half is connected with flabellum, and ribs of the fan lower surface is hinged, can jointed shaft be that center of circle rotary expansion folds flabellum.

Utility model content

Single page fan advantage is that structure is simple, with low cost, and shortcoming accounts for area greatly, not portable.Compared with single page fan, fan-folded fan structure is complicated, and processed complex, cost is high, and advantage is portable.

The technical problems to be solved in the utility model is to provide a kind of Foldable fan, not only portable, and also structure is simple, with low cost.

In order to solve the problems of the technologies described above, Foldable fan of the present utility model, comprise collapsible flabellum, staight shank, vertical support, flabellum has certain degree of hardness, and flabellum comprises multi-disc folding, and folding is asked and can be folded by organ folding mode, and folding number is odd number; Staight shank supports split with vertical, is divided into flabellum two sides; Staight shank and flabellum tail are rolled over hinged; Vertical support is rolled over hinged with flabellum head; Vertical support tail end establishes sliding sleeve, socket staight shank, can and can only move along staight shank; Under fan page folded state, the hinged axis coinciding of staight shank and vertical support and flabellum, staight shank and vertical support stacked, the two can synchronous rotary to one end of middle clamping Foldable fan leaf.

Vertical support is generally positioned at the flabellum longitudinal axis, also can depart from the flabellum longitudinal axis.

Foldable fan can also be provided with folding shaping device, makes it to keep folded state after folding for flabellum.

Folding setting mechanism can be outer attached structure, also can be the structure that flabellum is directly made.

The structure that flabellum is directly made can be the straight cutting tongue straight cutting mouth that flabellum folding end is directly made, also can be the oblique cutting tongue oblique cutting mouth that flabellum folding end is directly made, under flabellum folded state, socket can be inserted with the folded state of fixed fold flabellum by tongue.

The interlocking flange that the structure that flabellum is directly made can also be the first folding of flabellum, tail folding is directly made respectively in same one end, under flabellum folded state can the mutual snap close of flange with the folded state of fixed fold flabellum.

Described hinged can be the axis of staight shank, the upper one of vertical support, after filling in flabellum through hole, expansible blocked hole difficulty and return, and can be rivet interlacement, also can be core riveted joint, and core is exactly that vamp wears the hole of shoestring accessory used.

After using above-mentioned technological means, folding portable, the structure that can realize fan are simple, with low cost.

[detailed description of the invention]

As shown in Figure 3, the most basic Foldable fan scheme does not comprise extra flabellum setting mechanism, and after flabellum 10 is folding, the staight shank 20 being positioned at folding flabellum 13 both sides forms clamping structure with vertical support 30, folding flabellum 13 one end can be clamped after 90-degree rotation, this one end Foldable fan leaf 13 cannot be launched; Folding flabellum 13 other end, because of not restriction, can open because of elasticity reason part, can not keep desirable folded state.

In embodiment one, use heat-shrink tube 33 to make sliding sleeve 31, under fanning open state, vertical support 30 is positioned at the flabellum longitudinal axis.A bit of heat-shrink tube, inward-facing section is bonded in vertical support 30 tail end, and staight shank 20 penetrates in heat-shrink tube 33, and heating makes heat-shrink tube 33 be locked staight shank 20, keeps certain enclasping force.

In embodiment two, vertical support 30 tail end is formed with embraces clamping structure, forms sliding sleeve 31, and under fan open configuration, vertical support 30 departs from the flabellum longitudinal axis.

Fig. 9 shows structure, the working method of straight cutting tongue straight cutting mouth.Straight cutting tongue 51 is inserted sheets that flabellum tail folding 12 cross cutting goes out, can turning out backward, rolls over to top.After straight cutting tongue 51 is turned up, tail folding 12 is formed the socket of straight cutting tongue 51 shape, other whole cross cuttings in folding relevant position go out straight cutting mouth 52, and after flabellum is folding, all straight cutting mouth 52 positions are corresponding, form the through hole of through folding flabellum 13.The straight cutting tongue 51 be folded to, again to front lower folding, inserts through hole, in being connected in, folding flabellum 13 can not be launched, and realizes folding flabellum 13 and formalizes.

Figure 10 shows structure, the working method of oblique cutting tongue oblique cutting mouth.Oblique cutting tongue 53 is inserted sheets that flabellum tail folding 12 cross cutting goes out, and tongue 55 tilts, and oblique cutting tongue 53 can turning out backward, rolls over to top.First folding 11 relevant position cross cutting goes out oblique cutting mouth 54, and oblique cutting mouth 54 is not established in other foldings.The oblique cutting tongue 53 be folded to is again to front lower folding, and tongue 55 oblique cutting of inclination enters oblique cutting mouth 54, in being connected in, folding flabellum 13 can not be launched, and realizes folding flabellum 13 and formalizes.Compared with the straight cutting of Fig. 9, oblique cutting is more firm, not easily throws off.

Figure 11 shows structure, the working method of flange interlocking.First folding 11 upper end arranges flange 1, and tail folding 12 upper end arranges flange 4 64, and other foldings also can interlock intensity to increase by relative set flange.After flabellum is folding, first folding flange 1 can not detained as figure mode is staggered with tail folding flange 4 64, forms interlocking, folding flabellum 13 can not be launched, and realizes folding flabellum 13 and formalizes.
