Abstract

The present invention relates to an improved detachable clock and watch gear assembly structure, which divides the gear assembly into detachable and independent first and second devices; the first device comprises: main and pinion gear representing hour, minute and second hands, spiral spring wheel for storing energy and spiral spring for ringing; the second device comprises: time-controlled precision escapement wheel, pallet, balance spring and balance wheel; of which, the first device can clamp securely the main and pinion gears as well as spiral spring by using upper/lower plywood along with the fixed leg, so can the second device clamp securely the escapement wheel, pallet, balance spring and balance wheel in the same way; an fixed arm is extended from the upper/lower plywood at one side of the first device to clamp the second device and fix it by bolt for meshing and interlocking purpose; with this design, the first device can be checked or replaced in common repair or replacement process, helping to avoid error disassembly of the precision second device and difficult alignment or otherwise malfunction for easier and quicker assembly purpose.

Claims

1. An improved detachable clock and gear assembly structure, which is equipped with a gear assembly composed of detachable and independent first and second devices;

the first device comprises;

main and pinion gear representing hour, minute and second hands, spiral spring wheel for storing energy and spiral spring for ringing;

the second device comprises;

escapement wheel, pallet, balance spring and balance wheel;

it is characterized by that;

the first device can clamp securely the main and pinion gears, spiral spring wheel and spiral spring by using upper/lower plywood along with the fixed leg, so can the second device clamp securely the escapement wheel, pallet, balance spring and balance wheel in the same way;

moreover, an fixed arm is extended from the upper/lower plywood at one side of the first device to clamp the second device and fix it by bolt for meshing and interlocking purpose.

2. The improved detachable clock and gear assembly structure as claimed in claim 1, wherein fixed hole is set on the fixed arm extended from the upper/lower plywood of the first device, and round hole set on the upper/lower plywood of the second device, so as to insert the plug pin and fasten the both ends by nuts.
