Control device capable of adjusting position of handle shaft

Abstract

The invention discloses a control device capable of adjusting the position of a handle shaft. The control device comprises a first clamping plate, a first handle shaft, a second handle shaft, a driving wheel, a main wheel, a second clamping plate, a cross rail and a cross rail spring, wherein the driving wheel is respectively engaged with the main wheel and a gear on the first handle shaft; the gear on the first handle shaft, the driving wheel and the main wheel are arranged between the first clamping plate and the second clamping plate; the cross rail is fixed together with the first clamping plate through a fastening piece; the second handle shaft sequentially passes through the cross rail, the second clamping plate, the main wheel and the first clamping plate; the top part of the second clamping plate is provided with a groove; and the cross rail spring is arranged in the groove and is used for pressing one side of the cross rail. The invention has the advantages that: all parts are fixed between the first clamping plate and the second clamping plate, and the first clamping plate and the second clamping plate are fixed into a whole, so a machine core is easy and convenient to mount integrally; an annular groove of the second handle shaft is formed in a through hole of the cross rail, and the second handle shaft can be taken out only by eliminating the locking between the cross rail and the second handle shaft during disassembly of the handle shafts, so the loss caused by disassembly of the parts is reduced.

Description

technical field [0001] The invention relates to a control device for adjusting the position of the stem shaft of a watch, in particular to a device for controlling winding and time setting at an adjustable position by transmitting power through gears. Background technique [0002] For mechanical watches with complex functions, when the additional mechanism elements must occupy a large space in the movement, it will cause the stem to deviate from the middle of the watch. However, people are accustomed to the aesthetics that the stem is in the middle of the case. It would be more advantageous to devise a construction that uses two parallel offset arbors and transmits power through gear meshing, instead of the usual single part or aligned two part arbors. For example, the publication number US20010046186A1 discloses an adjustable position stem shaft control device for a watch, such as figure 1 and figure 2 As shown, in this device, the first stem 2 is fastened coaxially with...

AI Technical Summary

Problems solved by technology

This structure realizes the gear transmission adjustable position stem to control winding or time setting, but this structure has the following disadvantages: the groove on the second splint needs to be matched with the annular groove on the second stem, so the The dimensional accuracy of the parts is extremely high, which increases the difficulty of processing; the installation is difficult, and it is easy to damage the parts after repeated times, resulting in unnecessary waste

The adapter structure is inconvenient to disassemble, and the parts that have been disassembled hard cannot be reused

In addition, the structure is easy to wear at the gap during long-term use, resulting in dislocation and detachment, resulting in overall instability
