JPS58860Y2 - Structure of the bottom part of a portable watch case - Google Patents

Description

[Detailed description of the invention] This invention is a structure of the rear button part of a case for a portable sounding watch, which allows sound to be emitted from the rear button direction of the sounding watch, allows easy battery replacement, and provides a structure that is easy to assemble. It is.

In the case of a conventional watch that emits sound from the rear side of a case for a portable watch, it is customary to install the buzzer body and the battery in parallel under the module body.

However, the lead spring of the power source taken out from the battery has a small internal resistance of the battery, and unless it is a strong spring, contact will be poor, and the battery will be pressed more forcefully in the direction of the module body.

Further, the spring that connects the power source from the module body to the buzzer also requires a certain strength as described above, and is pressed from the direction of the module body.

When assembling these two spring inner lids into the body, the inner lids were pushed up, making it difficult to assemble the outer spring lids.

The present invention eliminates these drawbacks and provides a structure for the rear part of a sounding clock in order to improve ease of assembly.

An embodiment of the present invention will be described below with reference to FIG.

A male screw is provided on the outer diameter of the buzzer 1 and a female screw is provided on the inner diameter of the protrusion 2a on the inner surface of the inner cover 2, and the battery cover 3 is attached to the inner cover 2 on the same plane where it is screwed. In addition to providing a U-shaped groove 2b on the outer periphery of the inner lid 2,
The inner diameter wall surface 5a of the body 5 constitutes a packing box.

However, there is a middle pig packing 6 in the U-shaped groove 2b of the middle pig 2.
By winding and attaching the inner cover 2, the inner cover 2 is easily press-fitted into the barrel 5 using the inner cover insertion guide chamfered portion 5b as a guide.

Therefore, since the inner lid gasket 6 is compressed in the radial direction, its frictional force provides sufficient frictional force to withstand the pressure of the battery lead spring 8 that extracts power from the battery 7 and the lead spring 9 that connects the power to the buzzer 1, and also provides airtightness. It is to be ensured.

However, as shown above, the trunk 5 and the inner lid 2 are fixed via the inner lid packing 6, but the lower surface of the U-shaped groove 2b provided on the outer circumference of the inner lid 2 and the stepped portion of the outer lid 10 are also fixed. 10 The outer cover 10 and the barrel 5 are positioned in the vertical direction completely abutting against the surface a, and moreover, the outer cover 10 and the barrel 5 are engaged with each other.

Further, since the outer cover 10 is provided with a hole 10b for the battery cover 3, the battery 7 can be easily replaced by simply opening and closing the battery cover 3 without removing the outer cover 10.

As explained above, the present invention provides a structure for the rear part of a sounding clock that is easy to assemble and disassemble, and allows for easy battery replacement, and its effects are tremendous.
