Technical field:
The utility model relates to a kind of electric fan, the tilt adjustment structure on particularly a kind of calm blade fan.
Background technique:
In the prior art,, hand rest fan is in the past regulated the inclination angle, turn round the mode of operation of screw-clamped from the side, change worm screw or screw spiral into and promote stop, mode of operation from behind as Chinese patent 97242410.5 disclosed electric fan obliquity structures.After the improvement, because operating grip is in the dead astern of fan, fan can not forward the back to and go, so no matter when operate all accessible; This structure is because adopt spiral to promote means of retention, thus needn't bimanualness, and a hand torsional handle is just passable, because operation does not contact the fan of shaking the head and rotating, just can operate so driving fan, and can accurately finely tune, but this structure also has deficiency:
The first, adopt the mode of hand torsional handle to drive worm screw or screw spiral, hand needs bigger strength and governing speed slow, and it is pretty troublesome to operate;
The second, this structure more complicated, installation and maintenance are very inconvenient, and in addition, cost of production is also than higher.
The model utility content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the tilt adjustment structure on a kind of calm blade fan easy to operate, simple in structure and with low cost is provided.
Tilt adjustment structure on a kind of calm blade fan that provides according to the utility model, comprise the last arc plate and the arc lower plate that all have a concave surface and a convex surface, the concave surface of upper and lower arc plate all is provided with up, and the convex surface of last arc plate cooperates with the concave surface of arc lower plate and slidably links together.
The utility model also has following attached technical characteristics:
The described arc plate lower end surface of going up is provided with four chutes inwardly recessed and that be arranged in parallel, the outer side of the opening of each the bar chute blocking arm that all extended internally, described arc lower plate upper-end surface is provided with respectively four slide rails that are slidingly matched with four chutes, and the lower end surface of each slide rail all can be replaced with the blocking arm upper-end surface on the corresponding chute.
Described each described slide rail all is fixed on the arc lower plate upper-end surface by a riser.
The lower end surface of the air-flow formation component on the described concave surface of going up arc plate and the calm blade fan is connected, and the upper-end surface of the base on the convex surface of described arc lower plate and the calm blade fan is connected.
The upper-end surface of the base on the convex surface of described arc lower plate and the calm blade fan is one-body molded.
Tilt adjustment structure on a kind of calm blade fan that provides according to the utility model with respect to the advantage of prior art is:
First, in the utility model, comprise arc plate and arc lower plate, the convex surface of last arc plate cooperates with the concave surface of arc lower plate and slidably links together, the lower end surface of the air-flow formation component on the concave surface of last arc plate and the calm blade fan is connected, the upper-end surface of the base on the convex surface of arc lower plate and the calm blade fan is connected, stir the air-flow formation component with hand, last arc plate can slide on static relatively arc lower plate, because its face of being slidingly matched is a male and female face, thereby, air-flow formation component certain angle that can only tilt in the angular range that male and female face limits is fixed on the jet assembly that air-flow generates and also tilts synchronously thereupon, and then reaches the purpose of regulating the tilt angle, this structure only need gently be stirred with have gentle hands and be got final product, and it is very convenient to operate;
The second, in the utility model, realize regulating the purpose at tilt angle by being slidingly matched of last arc plate and arc lower plate, last arc plate and arc lower plate self structure are very simple, can be by the injection moulding once-through, thereby this structure is very simple, it is very convenient and with low cost to install and keep in repair.

Fig. 2 goes up the structural representation shaft side figure of arc plate convex surface up the time in the utility model;
Fig. 3 is the structure for amplifying schematic representation of I among Fig. 1;
Structural representation when Fig. 4 is zero degree for the utility model inclination angle;
Structural representation when Fig. 5 leans forward for the utility model;
Structural representation when Fig. 6 is the utility model hypsokinesis.
Embodiment:
Referring to figs. 1 through Fig. 6, tilt adjustment structure on a kind of calm blade fan that provides according to the utility model, comprise the last arc plate 3 and the arc lower plate 4 that all have a concave surface 1 and a convex surface 2, on, arc lower plate 3,4 concave surface 1 all is provided with up, also can be provided with down as required, the convex surface 2 of last arc plate 3 is fitted and is slidably linked together with the concave surface of arc lower plate 41, last arc plate 3 lower end surfaces are provided with four chutes 31 inwardly recessed and that be arranged in parallel, the outer side of the opening of each bar chute 31 blocking arm 32 that all extended internally, arc lower plate 4 upper-end surfaces are provided with respectively four slide rails 41 that are slidingly matched with four chutes 31, the lower end surface of each slide rail 41 all can be replaced with blocking arm 32 upper-end surfaces on the corresponding chute 31, in restriction, arc lower plate 3,4 length travel, guarantee that it does not separate, each slide rail 41 all is fixed on arc lower plate 4 upper-end surfaces by a riser 42, the number of chute 31 and the slide rail 41 that is slidingly matched with it can dispose as required, not necessarily is restricted to four.
Calm blade fan comprises jet assembly 8, air-flow formation component 6 and base 7, wherein, jet assembly 8 is installed in air-flow formation component 6 upper ends and is communicated with it, air-flow formation component 6 is installed in base 7 upper ends, the lower end surface of the air-flow formation component 6 on the concave surface 1 of last arc plate 3 and the calm blade fan is connected, and the upper-end surface of the base 7 on the convex surface 2 of arc lower plate 4 and the calm blade fan is connected or is one-body molded.
