This head pendulum angle controlling device D
1Carry out the size adjusting between controlling rod 6 and the flat board, make dull and stereotyped 8 crookedly upward and the pit 22 and the protuberance 24 of controlling rod 6 be set at certain distance on the length direction of controlling rod 6 as before, make on easily crooked downwards this two aspect of controlling rod 6 and carry out.By this controlling rod 6, can guarantee the rotation of bigger size adjusting and steering force that can be big operation controlling rod and carry out smoothly.
And, because owing to the shape of controlling rod 6 that makes simple in structure that is arranged on the protuberance 24 below the controlling rod 6 is also oversimplified, so, not only easy to manufacture, no matter controlling rod 6 is on which pivotal position, the degree of crook that can both guarantee controlling rod 6 is certain, and can stably carry out the rotating operation of controlling rod.
And, at this head pendulum angle controlling device D
1On, because controlling rod 6 and neck top 4 can be obtained by integrally moulded, flat board 8 usefulness sheet metals are made, so, the controlling rod 6 and the neck top 4 of complicated shape are simplified the structure, and can guarantee necessary elastic bending by dull and stereotyped 8 thickness of slab.
The embodiment of the invention 2 is that the protuberance as the supporting portion is arranged on neck top one side.Below will illustrate in greater detail this point by Fig. 9～Figure 10 b.And part identical in fact with embodiment 1 on these figure is used prosign, and omits its explanation.
Between the diapire 15 of neck top 4A,, be provided with protuberance 60 (with reference to Fig. 9) as the supporting portion near the place of back shaft 5, it from extend near the sidewall 30 another direction sidewall 10 near.Protuberance 60 plane shapes are rectangulars, and have certain fabric width.The length of protuberance 60, be at least can corresponding controlling rod main part 21 the pairing length of rotation angle, but preferably the amplitude with the diapire 15 of neck top 4A is consistent.
Below the controlling rod main part 21 on controlling rod 6A be not and head pendulum angle controlling device D
1In protuberance 24 similar things, but smooth structure (referring to Figure 10 a and Figure 10 b).
The structure of protuberance 60 is such, have identical projecting height near an end of a sidewall 9 to the part (one end side portion) of the position of about length overall 70% from distance, the part (another one end side portion) of another end from same position to close another sidewall 10 makes it to reduce gradually by an one end side portion is downward-sloping inchmeal.This can illustrate by following reason.
Head pendulum angle controlling device D in embodiment 1
1On, rotating operation pit 22 or the distance between steel ball 23 and the protuberance 24 by controlling rod 6 do not change, but on embodiment 2 head pendulum angle controlling device, on protuberance 60 and the above-mentioned the same diapire 15 that is arranged on neck top 4A, the design of plane shape rectangularity, therefore, distance between pit 22 or steel ball 23 and the protuberance 60 is partly shorter than this end side surface at the other end lateral parts of protuberance 60, therefore, just have the bending of controlling rod 6A, at the other end lateral parts of protuberance 60 than serious this problem of this end side surface part, therefore, can address this problem by the projecting height difference that protuberance 60 is set.
Be designed on this head pendulum angle controlling device at the projecting height with protuberance 60, as shown in figure 11, when steel ball 23 was mobile between 3 matching holes 17,18,19 of dull and stereotyped 8, the following of top contact dull and stereotyped 8 of steel ball 23 moved.At this moment, the controlling rod operating end part between dull and stereotyped 8 dual-side, unfixing on above-below direction as mentioned above, thus as on Figure 11 upward to arrow shown in, the top squeeze by steel ball 23 makes its crooked upward moving easily.And, between the pit 22 (steel ball 23) of controlling rod 6A and protuberance 60, go up because on the length direction of controlling rod 6A, be designed to certain distance, so, controlling rod 6A is when steel ball 23 is mobile between 3 matching holes 17,18,19 of dull and stereotyped 8, as the direction of arrow of the downward finger shown on Figure 11, crooked downwards as the strong point with the contact segment of protuberance 60 and controlling rod 6A.And when no matter steel 23 is which position in 17,18,19, as shown in figure 12, can both match with hole 17,18,19 in the top of steel ball, and controlling rod 6 returns to nature.And, when not designing such protuberance 60, also the plane shape of protuberance can be designed to along with the rotary motion trace of the described strong point the circular arc both sides of fixed central angle form the fan shape that 2 parallel circular arcs are arranged of extending.
As mentioned above, even embodiment 2 head pendulum angle controlling device, carry out the size adjusting between controlling rod 6A and dull and stereotyped 8, be dull and stereotyped 8 crooked upward and between the protuberance 60 of the pit 22 of controlling rod 6A and neck top 4A, be designed to certain distance and make and carry out aspect crooked downwards easily two of controlling rod 6A as before from making, thus, can guarantee to carry out larger sized adjustment, need not use big steering force operation controlling rod to carry out smoothly.
The head pendulum angle controlling device of aforesaid electric fan, from the pit of controlling rod on the close position of described back shaft, the diapire of controlling rod with neck top supported, simultaneously, because between the diapire on controlling rod and neck top, the supporting portion that forms the space is being arranged on the part of the controlling rod operating end of this strong point, so, size adjusting between controlling rod and the flat board, as before that flat board is upwards high crooked, and certain distance is set between the pit of controlling rod and protuberance crooked downwards easily this of controlling rod carried out aspect two, can guarantee bigger size adjusting, the steering force that big operation controlling rod is rotated can make it carry out smoothly.
In addition, the head pendulum angle controlling device of above-mentioned electric fan, it is dull and stereotyped because the controlling rod of its dual-side operation one end side portion is not fixed on the above-below direction, and have only the back shaft partial fixing on above-below direction, so, dull and stereotyped both sides are anti-back shaft parts, and just the matching hole part is crooked upward easily, can increase the scope of the size adjusting between flat board and the controlling rod.
The head pendulum angle controlling device of aforesaid electric fan, because the supporting portion is to be formed by the protuberance that highlights below controlling rod, the shape of controlling rod can be oversimplified its manufacturing not only may be easier, and, no matter controlling rod is in which pivotal position, the degree of crook of controlling rod is certain, can guarantee the rotating operation of stable controlling rod.
