Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable watch such as a wristwatch, and in particular, a mechanical fixing structure for a portable watch that is required to have excellent qualities such as waterproofness and shock resistance, such as a diving watch. It is related to.

An object of the present invention is to improve quality such as safety against external shocks and long-term stability in a portable watch such as a diving watch.

As for the mechanical fixing structure of conventional portable watches, in general watches, the body and back cover are configured to be detachable, and the watch mechanical body is attached from the back cover side of the case, and the back cover secures the inner frame, etc. The structure was generally mechanically fixed by pushing up through a mechanical fixing member.

In addition, in the case of high-pressure waterproof watches such as diving watches, a one-piece case with a body and case back integrated is also used to improve waterproofness, especially long-term waterproofness. Because the structure uses a type or spray-type glass fixing ring, the fixing force in the axial direction is not reliable, and if an external impact is applied, the glass dial ring and watch mechanism will move, resulting in damage to the structure due to the impact. There were problems with reliability and safety in terms of fixing performance and durability, such as scraping and scratches on some corners of parts.

The present invention eliminates the above-mentioned drawbacks of the conventional technology, and includes a dial support ring that is attached to the outer periphery of a dial holder ring that is held integrally with a watch mechanical body that is placed in a one-piece case in which a body and a back cover are integrally formed. A mechanical fixing gasket is configured, and a dial ring having a scale configured on its upper part and a glass are screwed to the one-piece case using a screw ring-type glass fixing ring, thereby firmly positioning the mechanical fixing gasket in the axial direction, and is an elastic member. The machine is securely fixed via the machine fixing gasket and dial support ring.

Detailed explanation will be given below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a one-piece case made of a metal material in which a body and a back lid are integrally formed. A dial ring 7 having a scale on its surface is provided above a mechanical fixing gasket 8 which is formed on the outer periphery of a dial support ring 9 that is integrally held on a watch mechanical body 2.
Press with .

The reinforced inorganic glass is placed on the upper step 1a of the one-piece case via the glass packing 3, and the glass 4 having the step 4a on the outer periphery is attached to the threaded part of the body 1 using a glass fixing ring 6 in the form of a screw ring. IbK is engaged and the tightening is fixed in the axial direction.

The axial position of the glass 4 is determined by the thickness of the buckle portion 7a of the dial ring 7, and the timepiece mechanism body 2 is fixed in a fixed position by the pressing force of the mechanical fixing gasket 8.

5 is a glass protection IJ ring made of synthetic resin, and 10 is a rotating bezel.

With this configuration, the glass, dial ring, etc. do not move even if a drop shock is applied, which eliminates the occurrence of chips, scrapes, and scratches on parts.

As explained above, the present invention provides a mechanical fixing structure in a one-piece case with a glass fixing ring that is screwed into the case to connect the glass, dial ring, mechanical fixing gasket (elastic member), dial holder ring, and watch mechanical body. By transmitting pressure force in the axial direction in series, the movement of each part during impact is reduced, and mutual parts are prevented from chipping, scraping, or
It solves problems such as scratches, and is useful as a mechanical fixing structure for high-pressure waterproof watches such as diving watches.

Claims (1)

[Claims] 1. In a one-piece case in which a body and a back lid are integrally formed, a watch mechanism body is placed on the stepped part of the case, and a dial holder ring for receiving a dial and a dial holder ring are placed on the watch mechanism body. By placing an elastic member on the outer periphery, placing a dial ring on the elastic member, placing a glass on the dial ring, and screwing a glass fixing ring onto the body to press the glass in the axial direction, the watch mechanical body is assembled. A mechanical fixing structure for a portable watch, characterized in that a watch mechanical body is fixed to the case via the respective members placed thereon.
