Description

Technical Field

[0001] The utility model relates to the technical field of blinds, in particular to an automatic speed regulating mechanism for multi-blind glass. Background Art

[0002] Built-in blinds insulating glass has the advantages of heat preservation and sound insulation of ordinary insulating glass and the convenient dimming performance of blinds. It is beautiful, generous, easy to operate, clean, hygienic and space-saving, so it has been more and more widely used at home and abroad. Common built-in blinds insulating glass is divided into ordinary single-chamber built-in blinds insulating glass and three-glass two-chamber built-in blinds insulating glass; the former is composed of inner glass, outer glass, frame, blinds blades, and blade adjustment mechanism composed of blade lifting mechanism and blade flipping mechanism; the latter is added with a layer of middle glass between the inner and outer glass of the former, which divides the space between the inner and outer glass into inner and outer cavities, further improving the heat preservation and sound insulation effects.

[0003] After searching, it was found that the Chinese utility model patent with the authorization publication number CN206386066U disclosed a blind with a variable speed rope reel. From its specification, it can be seen that the transmission ratio of the driving wheel 1 and the driven wheel 1 is greater than 1, which is a reduction transmission. The transmission ratio of the driving wheel 2 and the driven wheel 2 is less than 1, which is an acceleration transmission. When the driving wheel 1 is meshed with the driven wheel 1, the driving wheel 2 and the driven wheel 2 are not in contact; after the driving shaft slides to the left, the driving wheel 2 is meshed with the driven wheel 2, and the driving wheel 1 and the driven wheel 1 are not in contact. Thus, the speed adjustment is realized.

[0004] However, the Venetian blinds in the above patents have the following problems: (1) the speed change mechanism can only provide two rope winding speeds, and the speed adjustment range is small; (2) when adjusting the rope winding speed, it is necessary to manually pull or push the driving shaft, which makes it inconvenient to adjust the speed each time.

[0009] Preferably, the first driving mechanism is a second motor disposed on the sliding sleeve, and the second motor is transmission-connected to one end of the rotating shaft via a coupling.

[0011] Preferably, the second driving mechanism is an electric telescopic rod disposed in the first cavity, and the telescopic end of the electric telescopic rod is connected to the connecting rod.

[0012] The above technical solution can drive the sliding sleeve to slide on the guide rod by controlling the operation of the electric telescopic rod, and can make the secondary gear mesh with any speed gear.
