The utility model is provided with a rotation transmission shaft which is provided with a transmission gear connected with a rotation motor; the utility model is characterized in that the lower end of the rotation transmission shaft is provided with a rotation adjusting seat which is provided with an adjusting movable piece which is provided with a connecting hole used for connecting a rotation arm is arranged and a long strip-shaped eccentric distance adjusting hole; the rotation transmission shaft is a hollow shaft; the rotation transmission shaft is internally provided with an eccentric adjusting shaft; the lower end of the eccentric adjusting shaft is provided with an adjusting pulling fork matched with the adjusting movably piece; the utility model is provided with a rotation adjusting seat on the rotation transmission shaft, which ensures the eccentric distance between the rotation transmission shaft and the rotation arm to be adjustable, thus implementing the adjustment of the fanner rotation angle. The utility model saves the energy sources and improves the comfort of application, and is simple and convenient to be operated.

Description

The electric fan oscillating angle regulator

Technical field

The utility model belongs to a kind of control gear, particularly a kind of electric fan oscillating angle regulator.

Background technique

In the prior art, the panning angle of electric fan is fixed, and is general in 90～120 ° scope, i.e. the electric fan swing of can only shaking the head in the angular range of setting.The panning angle of electric fan depends on the eccentric distance of revolution part in the head-shaking device, and the angle that eccentric distance is greatly then shaken the head is big, and the little angle of then shaking the head of eccentric distance is little.Because the eccentric distance of revolution part has just been determined when design, so the panning angle of electric fan is also just fixing, in use can't change.The problem that above-mentioned electric fan exists is that because the population in China family is fewer and feweri, so electric fan usually is that a people uses separately, perhaps two, three people use together.Therefore, the angle of electric fan oscillating does not need so big sometimes, and the angle of shaking the head can cause waste too greatly on the contrary, wind does not blow in the needed scope of people, gone but blow to unwanted place, this had both wasted the energy, did not reach the intended purposes that people use electric fan again.

Summary of the invention

The technical problems to be solved in the utility model is that the problem that the existing electric fan oscillating angle of solution can not be regulated provides a kind of electric fan oscillating angle regulator.

The utility model has the transmission shaft of shaking the head, the driving gear that is connected with the motor of shaking the head is housed on the transmission shaft of shaking the head, its special way is, the adjustment seat of shaking the head is equipped with in lower end at the transmission shaft of shaking the head, on the adjustment seat of shaking the head, be equipped with one and regulate moving plate, there is one the attachment hole of rocking arm and the throw of eccentric adjustment hole of a long strip are installed on the adjusting moving plate, the described transmission shaft of shaking the head is a hollow shaft, an eccentric adjustment axle also is housed in the transmission shaft of shaking the head, is equipped with in the lower end of eccentric adjustment axle and regulates the adjusting shift fork that moving plate matches.

The utility model is installed the adjustment seat of shaking the head on the transmission shaft of shaking the head, and adopt eccentric adjustment axle and adjusting shift fork to be regulated to regulating moving plate, make the eccentric distance of shaking the head between transmission shaft and the rocking arm adjustable, thereby realized the adjustment of electric fan oscillating angle, in the process of using, people can be adjusted the panning angle of electric fan as required at any time, have both saved the energy, improved the travelling comfort of using again, and simple, convenient.

Embodiment

As shown in drawings, the utility model has the transmission shaft 6 of shaking the head, and the driving gear 7 that is connected with the motor of shaking the head is housed on the transmission shaft 6 of shaking the head, driving gear 7 and shake the head between the transmission shaft 6 and to be interference fit, both are tightly fixed together, so that transferring power; Shake the head transmission shaft 6 and driving gear 7 is positioned within the motor of shaking the head, and also can be installed in the outside of the motor of shaking the head; The adjustment seat 11 of shaking the head is equipped with in lower end at the transmission shaft 6 of shaking the head, the cross section of the adjustment seat of shaking the head 11 is the door font, the adjustment seat of shaking the head 11 and shaking the head links together with connecting head 9 between the transmission shaft 6, the bottom of connecting head 9 is a square, be assemblied in the door font frame of the adjustment seat 11 of shaking the head, make connecting head 9 and shake the head and to relatively rotate between the adjustment seat 11, the top of connecting head 9 is flat holes, the shake the head bottom of transmission shaft 6 is mounted in it, after both are fitted together, fixing with screw 8 again, guarantee firm and reliable connection, can not relatively rotate between the two; Lower inside in the adjustment seat 11 of shaking the head has two sliding-grooves, on the adjustment seat 11 of shaking the head, be equipped with one and regulate moving plate 12, described adjusting moving plate 12 is installed in the sliding-groove of the adjustment seat 11 of shaking the head, slide in front and back therein, has one the attachment hole of rocking arm and the throw of eccentric adjustment hole of a long strip are installed on adjusting moving plate 12; The described transmission shaft 6 of shaking the head is hollow shafts, an eccentric adjustment axle 2 also is housed in the transmission shaft 6 of shaking the head, Returnning spring 3 is equipped with in the upper end of eccentric adjustment axle 2, the lower end is equipped with and is regulated the adjusting shift fork 10 that moving plate 12 matches, fork arm on the shift fork 10 is arranged in the throw of eccentric adjustment hole of regulating moving plate 12, rotation shift fork 10, can stir adjusting moving plate 12 seesaws in the adjustment seat 11 of shaking the head, thereby change the eccentric distance of shaking the head between transmission shaft 6 and the rocking arm, and then change the panning angle of electric fan; Also have four locating slots in the bottom of connecting head 9, an associated fin is arranged on the top of shift fork 10, both combine under the effect of Returnning spring 3 all the time, and shift fork 10 can not arbitrarily be rotated, and are fixed on the position of setting regulating moving plate 12; When needs are regulated the eccentric distance of shaking the head between transmission shaft 6 and the rocking arm, to pressing down eccentric adjustment axle 2, the fin on shift fork 10 tops and the locating slot of connecting head 9 bottoms are thrown off, rotating eccentricity adjusting axle 2 gets final product again; The locating slot of connecting head 9 bottoms also can be six or eight, determines according to actual needs; At the top of eccentric adjustment axle 2 a manual tune handle 1 is housed also, the panning angle that is used for regulating electric fan has the sign of electric fan oscillating angle on manual tune handle 1, so that determine the panning angle of electric fan when using; A positioning ring 4 also is housed on the transmission shaft 6 of shaking the head, so that the transmission shaft 6 of will shaking the head is installed on the support in the casing, positioning ring 4 usefulness Cock screws 5 are fixing.

The also available automatic controller of head-shaking device of the present utility model is controlled, when adopting automatic controller control, need the Returnning spring 3 and the manual tune handle 1 on eccentric adjustment axle 2 tops are removed, on the top of eccentric adjustment axle 2 an angle adjustment motor being installed gets final product, simultaneously, because the angle adjustment motor itself has the function of self-locking, therefore, also need the locating slot of connecting head 9 bottoms and the fin on shift fork 10 tops are removed, so that the operation of angle adjustment motor.
