Abstract
The utility model relates to an automatic light shielding device, comprising blades (10), a guy rope (20) and a rope (39). The automatic light shielding device also comprises a speed-reducing transmission mechanism which comprises a gear (12), a gear (13), a gear (16), a gear (18), a worm screw (14) and a worm wheel (15), wherein, the worm screw (14) is fixed on the shaft of the gear (13); the gear (16) and the worm wheel (15) are concentric and coaxial; the shaft center of the gear (18) is connected with a main shaft (19). The automatic light shielding device also comprises an automatic lifting mechanism which comprises a roller cone (31), a chain (32), a roller cone (33) and a plane wheel (34), wherein, the plane wheel (34) and the roller cone (33) are concentric and coaxial; one end of the rope (39) is fixed on the plane wheel (34).
Description
The utility model relates to a kind of autocollimatior.
Existing venetian blind type curtain is applicable to hotel or restaurant, and this venetian blind type curtain all uses manual mode to operate, and it is not too convenient to use, and uses manual operations, easily disease carrying germ.On existing automobile, then use the door curtain made of cloth to keep the sun off, use the door curtain made of cloth on the automobile, the weak effect that is in the light, it is permanent to use, and easy dirty distortion influence attractive in appearancely, and uses hand-manipulated, very inconvenient.
The purpose of this utility model provides a kind of autocollimatior that is applicable to that hotel, restaurant and big car use.
The purpose of this utility model is to realize like this, the utility model comprises blade (10) and lead (20), rope (39), according to feature of the present utility model, it also comprises the reduction gearing mechanism that is made of gear (12), gear (13), gear (16), gear (18), worm screw (14) and worm gear (15), wherein worm screw (14) is fixed on the axle of gear (13), gear (16) and worm gear (15) concentric co-axial, gear (18) axle center also is connected with main shaft (19).According to other feature of the utility model, it also comprises the automatic hoisting mechanism that is made of gear wheel (31), chain (32), gear wheel (33), face wheel (34), wherein face wheel (34) and gear wheel (33) concentric co-axial, rope (39) one ends are fixed on the face wheel (34).
Advantage compared with prior art of the present utility model and good effect are significant, the utility model adopts the full-automatic lifting of adjusting the be in the light blade angle and the blade that is in the light, be installed on the large and small car, can reduce the sunlight direct projection that the personnel of riding are subjected to, use in the hotel, can make things convenient for customers, improve service quality.At heavy clouds and rainy weather, adjust blade angle, can also increase in the car or room brilliancy.
Fig. 1 and Fig. 2 are an embodiment blade turning mechanism of the utility model schematic diagrames.
Fig. 3 is an embodiment blade of a utility model elevating mechanism schematic diagram.
Fig. 4 is an embodiment blade structure of a utility model schematic diagram.
The drawing reference numeral explanation:
10 blades, 11 motors, 12 gears, 13 gears, 14 worm screws, 15 worm gears, 16 gears, 17 gear shafts, 18 gears, 19 main shafts, 20 leads, 31 gear wheels, 32 chains, 33 gear wheels, 34 face wheels, 39 ropes.
Referring to accompanying drawing 1 and Fig. 2, show an embodiment blade angle of the utility model guiding mechanism schematic diagram.The blade angle guiding mechanism comprises three cover reducing gears, the gearratio of gear (12) and gear (13) is 6:1, the gearratio of worm screw (14) and worm gear (15) is 15:1, the gearratio of gear (16) and gear (18) is 5:1, three cover reducing gears are such associated working, worm screw (14) links to each other with the axle center of gear (13), gear (16) and worm gear (15) are concentric, be fixed together by gear shaft (17), gear (18) axle center is connected with hexagonal main shaft (19), when motor (11) transmission, by by gear (12), gear (13), gear (16), gear (18), the reduction gearing mechanism that worm screw (14) and worm gear (15) constitute drives hexagonal main shaft (19) and rotates, thereby makes blade (10) run-off the straight under the drive of the rope (20) that links to each other with main shaft (19), thereby the light of blade is passed in change, reaches to change purpose indoor or interior illumination of car or brightness.
Referring to accompanying drawing 3, show the structure chart of an embodiment of the utility model elevating mechanism, among the figure, elevating mechanism is made of gear wheel (31), chain (32), gear wheel (33), face wheel (34), wherein gear wheel (31) and gear wheel (33) are realized drive connection by chain (32), and face wheel (34) and gear wheel (33) are coaxial with one heart, when driven by motor gear wheel (31) rotates, drive gear wheel (33) by chain (32) and rotate, thereby face wheel (34) is rotated.
