Description
Technical field
The utility model belongs to the technical field of toy helicopter, is specifically related to a kind of toy helicopter blade mounting structure of scalable propeller pitch angle.
Background technology
The blade propeller pitch angle of toy helicopter (comprising model helicopter) has determined lift, torsional moment size.The blade of existing toy helicopter and blade press from both sides once producing, and the propeller pitch angle of its blade is just decided, and that is to say, no matter in plant processes or in the user plays process, the propeller pitch angle of blade all is nonadjustable.There is following problem like this: 1, for the producer, inconvenience below existing: (1), for coaxial pair of oar toy helicopter, to keep balance be crucial to the moment of double-layer propeller up and down; Therefore; The producer must modulate the moment of double-layer propeller up and down in process of production, makes them keep balance, but because the propeller pitch angle of blade is non-adjustable; The helicopter toy that drives by different dynamic mechanism respectively for double-layer propeller up and down; Can only regulate very trouble through regulating actuating unit, regulating measure is limited; And for double-layer propeller is by coaxial pair of oar toy helicopter of same actuating unit driving up and down, shortage is regulated leeway and regulating measure especially; (2), for the toy helicopter of the different model of same manufacturer production because size, the weight of various model toy helicopters have nothing in common with each other, the lift that needs is different; And blade and blade press from both sides once producing; Its propeller pitch angle and lift are unique definite, no longer adjustable; Therefore; The toy helicopter of different model need be equipped with the blade of different model, can not realize between the toy helicopter of different model that blade is general, and this increases production cost and management cost undoubtedly.2, for the user, also have inconvenience: the blade of (1), high speed rotating damages easily, when the blade of a certain toy helicopter damages, just is difficult to find the blade of coupling to be changed, thereby blade damages and means that just whole toy helicopter scrap; (2), for coaxial pair of oar toy helicopter, if wherein one deck propeller blade distortion, perhaps the motor speed of two-layer screw occurs inconsistently up and down, then the moment of double-layer propeller can't keep balance up and down; (3) even for the toy helicopter of individual layer screw, also must maintenance coordinate with two propeller blades of one deck, if wherein screw distortion, just the lift of two screws could be coordinated.
The utility model content
The purpose of the utility model is to overcome above-mentioned shortcoming and toy helicopter blade mounting structure that a kind of scalable propeller pitch angle is provided, and its propeller blade propeller pitch angle can step-less adjustment.
Its purpose can realize by following scheme: a kind of toy helicopter blade mounting structure of scalable propeller pitch angle; Comprise the rotor shaft of vertical installation, the horizontal stub shafts of laterally installing, blade folder, blade; Horizontal stub shafts is fixedly mounted on the rotor shaft, the central axis bearing of trend of horizontal stub shafts be rotor shaft radially; The nearly center-side of blade is connected on the blade folder, is in its main feature, and the blade folder is movably arranged on the horizontal stub shafts and can rotates around the central axis of horizontal stub shafts; Also be provided with the adjusting support, regulate support and horizontal stub shafts or rotor shaft and directly be fixed together, regulate in the support adjusting screw(rod) is installed, the central axis of adjusting screw(rod) is vertical with the central axis antarafacial of horizontal stub shafts; Adjusting screw(rod) is fixedly connected with the adjusting support in the axial direction and is making progress in week and regulating the support flexible connection; A wherein segment length of adjusting screw(rod) is formed with external screw thread; The blade clamping is connected with a regulating block surely, and regulating block is formed with screw, and regulating block utilizes the external thread section of this screw and adjusting screw(rod) to twist and connects.
Said adjusting support is the U font; Said adjusting screw(rod) passes the both wings that support regulated in the U font, and said regulating block is between the both wings of regulating support, and adjusting screw(rod) is fixedly connected with a wherein wing of regulating support in the axial direction.
Regulate support and be fixed with annular protruding rib, the adjusting screw(rod) correspondence is formed with annular groove, and annular protruding rib embeds in the annular groove.
Regulate support and be provided with annular groove, the adjusting screw(rod) correspondence is formed with annular protruding rib, and annular protruding rib embeds in the annular groove.
The central axis of adjusting screw(rod) is a horizontal direction.
The utlity model has following advantage and effect:
One, the utility model can utilize adjusting screw(rod) to promote the blade folder to rotate around horizontal stub shafts, thereby infinitely regulates the propeller pitch angle of blade, the infinitely lift of adjustable screw blade, torsion, and then have the following advantages:
1, as far as the producer, has the following advantages: (1), can modulate easily in process of production and realize the equalising torque of double-layer propeller up and down by the coaxial pair of oar toy helicopter that same actuating unit drives for double-layer propeller up and down; (2), the toy helicopter of same producer different model, different manufacturers different model can general blade, reduces cost, be convenient to produce and management.
2,, have the following advantages as far as the user: (1), when the blade of a certain toy helicopter damages, can find the replacement blade at an easy rate, after the replacement lift is transferred to suitable getting final product, scrap and be unlikely to integral body; (2), during wherein certain a slice blade distortion of a certain toy helicopter, can realize double-layer propeller torsional moment balance up and down, or realize that two blades of individual layer screw coordinate through regulating the approach of propeller pitch angle; (3), as far as coaxial pair of oar toy helicopter, when wherein two motor speeds are inconsistent, can realize the torsional moment balance through the propeller pitch angle of adjustable screw oar.
Though the propeller pitch angle of two toy helicopters often needs to regulate, need the amplitude of adjusting also little, as long as rotate the bigger variation that adjusting blade propeller pitch angle just can cause lift, torsion slightly.The utility model utilizes these characteristics just dexterously; Conventional thinking breaks traditions; In conjunction with any object (particularly plastics) but characteristics of slight deformation all change " slide block " in traditional lead screw transmission mechanism the switch block (being regulating block) of rotation into, directly promote the blade folder by adjusting screw(rod) and rotate; Both can satisfy the needs of the amplitude of accommodation, but simplified structure again.
Three, because screw mechanism has self-locking property, so propeller pitch angle once adjusting, just automatically locks, passive reverse change can not take place because blade bears wind-force.
