Abstract
The utility model discloses a wind guiding grid and wind driving speed regulator which is an adjusting device suitable for various blade rotating fans to adopt the wind guiding grid driven by wind power. The utility model is characterized in that conical surface and radical direction braking is adopted and a speed regulating turn knob of wind guiding grid with fine teeth thread is adopted, a braking sleeve with an inner conical surface is cooperated with a bearing with an outer conical surface circular bead in order to obtain the ideal micro adjusting rotation speed to obtain the effect that the blown wind is similar to the natural wind. The utility model has the advantages of simple structure, easy fabrication, easy regulating and sensitive speed regulation performance and the required rotating speed of the wind guiding grid is easy to be selected.
Description
The utility model relates to a kind of rotary blade fan guiding-grid wind-drive arrangements for speed regulation, is the parts of rotary blade fan.
At present, the rotary blade fan of selling on the market, the wind-drive speed regulating structure of its guiding-grid is to braking with planar axes.In actual use, speed governing is sensitive inadequately, normal phenomenon unsatisfactory appears, if transfer slow guiding-grid rotating speed, change a period of time slightly after, the phenomenon that appearance stops slowly, if transfer fast guiding-grid rotating speed, change a period of time slightly after, it is very fast rotating speed to occur, make us dazzled, feel under the weather.
The purpose of this utility model provides a kind of speed governing sensitivity, easily obtains the arrangements for speed regulation of the rotary blade fan guiding-grid wind-drive of comparatively satisfied wind speed.
Structure of the present utility model mainly comprises platen, guiding-grid speed governing knob, locking nut, bearing, axle, spring, braking sleeve, screw, guiding-grid, wheel seat etc.It is characterized in that the conical surface radially brakes, guiding-grid speed governing knob is embedded with the fine thread metalwork, and wheel seat is in aggregates with the bearing drive fit that has the male cone (strobilus masculinus) shoulder.(or key cooperates or be injection molded into one as inserts) braking is with inner conical surface, and axially evenly distributing along garden week has 6 grooves holes, and spring is a column-style.When screwing guiding-grid speed governing knob, the column-style spring is compressed, the braking sleeve reach, and the inner conical surface of braking sleeve contacts with the bearing that has the male cone (strobilus masculinus) shoulder, produces radially braking action, and the guiding-grid rotating speed is descended.When unscrewing guiding-grid speed governing knob, its effect is opposite, the guiding-grid faster rotational speed, its effect is the air-flow that produces when using the flabellum rotation, the driving guiding-grid rotates, screwing and loosening in the process, can choose required guiding-grid rotating speed arbitrarily, obtain satisfied wind speed.
Characteristics of the present utility model are simple in structure, are convenient to make assembling, and easy to adjust, the speed adjusting performance sensitivity is transferred to satisfied air-supply effect easily.
Accompanying drawing is one of embodiment of the present utility model, and Fig. 1, Fig. 2 screw phase diagram and rotary blade fan guiding-grid wind-drive arrangements for speed regulation relaxation state figure with rotary blade fan guiding-grid wind-drive arrangements for speed regulation respectively.
Among Fig. 1, Fig. 2:

11. axle
Fig. 1 rotary blade fan guiding-grid wind-drive arrangements for speed regulation screw phase diagram.
Axle 11 is one and has the groove multidiameter shaft that M8 * 1 helical thread portion has reached the spring seat effect, with 20
#The steel car becomes.This axle is fastened on the frame 10, and frame is injection molded with engineering plastics.Have the bearing 9 of male cone (strobilus masculinus) shoulder, make, be slidingly fitted on the axle 11 with powder metallurgy.Be contained in the braking sleeve 6 on the axle 11, one section inner conical surface is arranged, along axially opening 6 groove holes in 6 inner conical surface garden weeks of braking sleeve.Braking sleeve is injection molded with engineering plastics.When braking sleeve 6 is compacted, just open, restore to the original state when loosening.Between braking sleeve 6 and bearing 9 spring 8 is housed, spring 8 usefulness carbon spring steel wiress are made.The effect of spring 8 is that braking sleeve 6 is resetted rapidly.M8 * 1 locking nut 3 is used to regulate the distance between braking sleeve 6 and the bearing 9.Platen 3 usefulness engineering plastics are injection molded, are fixed on on the injection molded wheel seat 5 of engineering plastics with two screws 2, play protection and decorative effect.With the injection molded guiding-grid speed governing knob of engineering plastics, be embedded with the metalwork of M8 * 1 screw thread, be threaded with axle 11.When guiding-grid speed governing knob is in when screwing state, braking sleeve 6 reaches, spring 8 is compressed, this moment braking sleeve 6 inner conical surface and the male cone (strobilus masculinus) of bearing 9 be close to.The guiding-grid 4 injection molded with engineering plastics do not change, and wind is directed.
Fig. 2 rotary blade fan guiding-grid wind-drive arrangements for speed regulation relaxation state figure.
Guiding-grid speed governing this moment knob 1 is in relaxation state, and braking sleeve 6 is moved under spring 8 effects backward, and the male cone (strobilus masculinus) of the inner conical surface of braking sleeve 6 and bearing 9 is separated, and guiding-grid is in the fastest rotating speed state.
