Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 2-4, a kind of oscillating mechanism for fan heater, comprise top cover 1, rotating main body 2 and base 3, be provided with in rotating main body 2 and turn support 4, gear motor 5, cam 6 and connecting rod 7, also be provided with rotating shaft 9 and bearing A10 in rotating main body simultaneously, rotating main body 2 is fixed with bearing B11, base 3 is fixed with disk 8 and supports iron hoop 12.One end of rotating shaft 9 is the end of thread, and the other end is cylindrical end, and the end of thread of gear motor 5 and rotating shaft 9 is all fixed on and turns on support 4; Cam 6 is fixed on the turning cylinder of gear motor 5; One end of connecting rod 7 is fixed on the cylinder end face of cam 6 lower end, and the other end is fixed on the circular cylinder end face of disk 8; Outer ring and disk 8 circular groove of bearing A10 are fixed, and the cylindrical end lower surface interference of inner ring and rotating shaft 9 kills.
The major function of bearing is supported mechanical rotary body, reduces the mechanical load coefficient of friction of plant equipment in transmission process.Gear motor 5 starts, power and movement locus is transmitted by cam 6 and connecting rod 7, because rotating shaft 9 and the interference of bearing A10 inner ring kill, form an axial-rotation free degree on the base 3, the rotating main body 2 of base 3 upper end is formed rotate, the bearing B11 that rotates through between the two connects, and rotary support face is close to linear contact lay, reduce resistance of shaking the head, also slow down catching phenomenon; Bearing B11 also rolls and rotates on support iron hoop 12 simultaneously, support the ring plate that iron hoop 12 is two circular arcs axisymmetric relative to rotating shaft 9, the rotational trajectory of bearing B11 and the panning angle of rotating main body 2 can be limited, produce position-limiting action, what decrease rotating main body 2 rocks gap, the reliability that improve shakes the head turns to.
As shown in accompanying drawing 2,5, rotating main body 2 internal fixtion has support A15, base 3 is fixed with support B17, in rotating main body 2, center is provided with at least one support link 18, and vertically run through support A15 and support B17, the upper end of support link 18 is fixed by nut A14 and top cover 1, its lower end is fixed by nut B16 and support B17, support A15 is the fixed support point that support link 18 is passed, support B17 can the lower end of fixed support connecting rod 18, and support A15 and support B17 determines the linearity of support link 18.When rotating main body 2 rotates, because support link 18 is positioned at the center of rotating main body 2, there is enough gaps between the two and non-interference, support B17 fixes on the base 3, and base 3 is fixed, therefore the support link 18 fixing with support B17, and fixing top cover 1 does not also all rotate with support link 18, achieve rotating main body 2 to shake the head rotation, and top cover 1 maintains static.Can steady placing articles on top cover 1, add the practicality of product.
Embodiment 2
As shown in accompanying drawing 6-7, substantially the same manner as Example 1, difference is: base 3 fixedly mounts bearing C13, and the bottom exterior layer of rotating main body 2 offers the swing-around trajectory caved inward, and the effect of swing-around trajectory is identical with support iron hoop 12, when rotating main body 2 rotates, bearing C13 rolls along swing-around trajectory and rotates, and the rotational trajectory of swing-around trajectory restriction bearing C13 and the panning angle of rotating main body 2, produce position-limiting action, what decrease rotating main body 2 rocks gap, the reliability that improve shakes the head turns to; The bearing C13 that rotates through between rotating main body 2 and base 3 connects, and rotary support face, close to linear contact lay, reduces resistance of shaking the head, and also slow down catching phenomenon.
