A starting mechanism of a mechanical timekeeping watch

Abstract

The invention discloses a starting mechanism of a mechanical time-telling watch. According to the starting mechanism, a through groove is formed on a spacer ring, and a pull core support is fixed in the through groove of the spacer ring; a connecting sleeve is respectively connected and fixed with one end of a pull core and a square end of a shifting hander as a whole, and the other end of the pull core is a free end; the pull core which is sheathed with a waterproof sealing pipe and a pressure spring penetrates through a connecting block and the pull core support; the pressure spring is arranged in a range of the length of the support; the connecting block is fixedly arranged at a gap formed on the pull core; the pull core penetrates through the connecting block, and the connecting block is fixedly connected with a shafting block; the shafting block in contact with or separated from a movement time-telling starting plate; and upper and lower ends of the exterior of the spacer ring are provided with waterproof rubber rings. The starting mechanism of the invention is advantageous in that: because waterproof rubber rings for sealing are arranged between the spacer ring and a watchcase, and a waterproof sealing pipe is arranged between the spacer ring and the inner pull core, the contact between the exterior and the interior is obstructed from an outermost end, and sealing is carried out from the interior, thereby enabling favorable dustproof and waterproof effects to be achieved. According to the starting mechanism, a sealing box is omitted, which enables a watch with a standard size to be small and thin.

Description

technical field

[0001] The invention relates to a starting mechanism of a mechanical timekeeping watch, in particular to a starting mechanism of a mechanical timekeeping watch with waterproof performance and improved structural performance. Background technique

[0002] A mechanical watch with a timekeeping function, commonly known as a "request watch", realizes the timekeeping function through a timekeeping mechanism arranged inside the movement. The timekeeping start mechanism of the repeater needs to process a through hole on the side wall of the case to meet the power transmission from the outside to the internal components. At this time, the movement inside the case is in direct contact with the air, which cannot meet the requirements of dustproof and waterproof. Chinese patent CN101846964A discloses a waterproof mechanism of a mechanical timekeeping watch, such as Figures 1 to 3 As shown, one end of the compression spring 1 is installed on the positioning head of the...
