Embodiment
Below in conjunction with accompanying drawing the utility model is made concrete further instruction.A kind of New Type of Fan steering head, it comprises base 1 and is movably articulated in inverting seat 3 on the base 1 by rotating shaft 2, it is characterized in that: be provided with many grades of positioning work pieces between described base 1 and the inverting seat 3, described many grades of positioning work pieces comprise the gear sheet 4 that is fixedly connected with base 1, described gear sheet 4 is provided with several positioning holes 41 at same circumference, be provided with the location hoodle 5 that can cooperate with positioning hole in the described inverting seat 3 accordingly, a wherein side of described inverting seat 3 is provided with the torsional spring slot 61 that precompressed torsion spring 6 is installed, and 6 liang of stressed pin of described precompressed torsion spring place respectively on inverting seat 3 and the base 1.
Be provided with blind hole 7 in the described inverting seat 3, blind hole 7 is built-in with loaded spring 51, and described location hoodle 5 places outside the loaded spring 51.
Described location hoodle 5 is for being arranged at the spherical steel ball in the blind hole 7, and described spherical steel ball places on the interior loaded spring 51 of blind hole, steel ball is in all the time ejects the gear sheet state that compresses.Make steel ball can press as in the positioning hole 41 on the gear sheet fan attachment elevation angle.
Described location hoodle 5 is the pin of spherical round end, and described pin places on the interior loaded spring 51 of blind hole, pin is in all the time ejects the gear sheet state that compresses.
Described base 1 madial wall is provided with the torsion spring hole 62 that precompressed torsion spring 6 stressed pin are installed, and makes inverting seat can be subject to the resilient support of spring, and adjusts the elevation angle of inverting seat under the effect of external force.
Described gear sheet 4 upper punches are pressed with outstanding its surperficial connecting sheet 42, and the mounting hole 43 that described connecting sheet 42 buckles on the base 1 is interior fixing.
Positioning hole 41 on the described gear sheet 4 is the long waist typed through hole that the punching press of location piece bulk material forms, and described positioning hole also can be manhole.
Described base 1 is provided with hinging hole, described hinging hole one side is irregularly-shaped hole 11, opposite side is manhole 12, and described rotating shaft 2 one ends are provided with and cooperate anti-rotation boss 21, the described rotating shaft the other end to be provided with screw thread with profiled holes and have nut 22 to be spirally connected with it, when therefore rotating shaft being installed, rotating shaft can be fixed in the irregularly-shaped hole not rotatable, drives rotating shaft when preventing from adjusting the fan elevation angle and rotates, and shines into the nut that is spirally connected with it and gets loose, for strengthening relaxation effect, described nut 22 is self-locking nut.
Working principle: during assembling, the mounting hole 43 that first connecting sheet 42 on the gear sheet 4 is buckled on the base 1 is interior fixing, then loaded spring 51 and location hoodle 5 are installed in the blind hole of inverting seat, and the inverting seat that will be provided with at last the precompressed torsion spring is fit in the groove of base, and is movably hinged by rotating shaft 2.Locate hoodle this moment under the elastic force of loaded spring 51, and the part of location hoodle is pressed in the positioning hole 41 on the location piece.Need to first overcome the elastic force of precompressed torsion spring and frictional force between location hoodle and gear sheet as needing to rotate inverting seat this moment, so when the elastic force of configuration precompressed torsion spring, need its elastic force will be enough to offset even be greater than the power that the fan main frame is pulled inverting seat.Therefore when preventing that fan from naturally drooping, the user only need to apply the frictional force that overcomes between hoodle and gear sheet can pull inverting seat, realizes adjusting the purpose at the fan air-supply elevation angle.Wherein need to illustrate the time, described gear sheet 4 is provided with several positioning holes 41 at same circumference, and inverting seat and gear sheet rotating center are on the same center of circle, therefore when rotating inverting seat, no matter how inverting seat swings, and the movement locus of location hoodle is all the time on the circumference that positioning hole 41 distributes.The pressure that rotates simultaneously inverting seat can force the location hoodle to overcome loaded spring pressure to break away from positioning hole, when arriving next position of positioning hole, under the elastic force of loaded spring, will locate hoodle and be pressed in the positioning hole fixingly, plays the effect at the restriction fan elevation angle.
Obviously, above-described embodiment only is for example clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of claims of the invention.
