Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
As shown in fig. 1 and fig. 2, the gear transmission lock body based on the gourd thumb wheel lock cylinder provided by the invention comprises a lock cylinder, a lock cylinder driving gear, a first intermediate gear, a second intermediate gear and a driving 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.
Further, along the circumferential direction of the lock cylinder driving gear, the distance between the meshing position of the lock cylinder driving gear and the first intermediate gear and the meshing position of the lock cylinder driving gear and the second intermediate gear is greater than the length of the notch along the circumferential direction of the lock cylinder driving gear. The structure is arranged to ensure that when the lock cylinder driving gear rotates, the lock cylinder driving gear is meshed with at least one of the first intermediate gear and the second intermediate gear.
