Description

Technical Field

[0001] The utility model relates to the technical field of watch pointers, in particular to a rotating and telescopic structure of a watch pointer. Background Art

[0002] A watch is a portable timepiece that is carried or worn by people. It is also called a wristwatch. Common materials for watches include leather and nylon.

[0003] Traditional watches display time in a uniform and monotonous manner, usually including a dial with time scales and hour, minute and second hands that display hours, minutes and seconds respectively.

[0004] The hour and minute hands on the watch dial rotate around the center point of the dial, and the time information is displayed by the circular rotation of the hands in fixed steps.

[0005] For example, the prior art Chinese patent publication number "CN220121156U" provides a watch pointer rotating and telescopic structure, including an original minute wheel of the movement and a large splint, the outer surface of the original minute wheel of the movement is fixed with a driving turntable, the upper surface of the large splint is provided with a slot, the upper surface of the large splint is fixed with a minute scale, a fixing pile is sleeved inside the slot, the upper surface of the driving turntable is provided with a through hole, the inside of the through hole is riveted with a rivet, the outer surface of the rivet is rotatably connected to the minute hand, the fixing pile is cross-shaped, the rivet is T-shaped, and the upper surface of the minute hand is provided with a hollow groove.

[0006] When the device drives the turntable to rotate the minute hand, the minute hand through hole moves with the rivet, and the minute hand hollow groove slides freely along the fixed pile. The movement trajectory of the upper end of the minute hand will form a special shape, and the corresponding minute scale can be designed. The time display is more interesting and novel than traditional indications, avoiding aesthetic fatigue among consumers.
