Detailed Description
The present invention will be described in detail with reference to the following embodiments. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.
As shown in fig. 1 and fig. 2, according to the utility model provides a pair of gear drive lock body based on calabash thumb wheel lock core, including lock core, lock core drive gear, first intermediate gear, second intermediate gear and drive shaft gear, wherein: the lock cylinder driving gear is sleeved on the lock cylinder, and the shifting wheel of the lock cylinder can drive the lock cylinder driving gear to rotate; the lock cylinder driving gear is respectively meshed with the first intermediate gear and the second intermediate gear; the first intermediate gear and the second intermediate gear are meshed with the driving shaft gear.
Further, lock core drive gear is ring gear, be provided with a breach on the lock core drive gear, breach intercommunication lock core drive gear's interior region and outside region. The inner area and the gap of the lock cylinder driving gear are used as the accommodating area of the thumb wheel. When the thumb wheel rotates, the thumb wheel forms an acting force on one side of the notch, and then the lock cylinder driving gear is driven to rotate. Guide surfaces are arranged on two sides of the notch, and the guide surfaces on the two sides are arranged oppositely.
