Abstract

A watch bottom cover made of ceramic comprises a metal outer ring (1) and a ceramic inner core (2). The metal outer ring (1) is ring-shaped. The shape of the ceramic inner core (2) and that of a hollow part inside the metal outer ring (1) coincide, and the ceramic inner core (2) and the metal outer ring (1) are fixedly mounted together. Further provided is a radio controlled watch using the watch bottom cover, comprising a watch shell and a movement disposed in the watch shell. The watch bottom cover is mounted at the bottom of the watch shell. The structure of the ceramic inner core (2) in cooperation with the metal outer ring (1) not only enables the penetrability of a received signal of the radio controlled watch to be strong, but also has advantages such as wear-resistance, very high melting point, and good electric insulation performance. Particularly, the structure has excellent chemical stability and oxidation resistance, and has high strength under a high temperature situation, good heat resistance, and strong corrosion resistance. The structure can still resist corrosion of acid substances and neutral substances at a high temperature, and may prolong the watch service life.

Description

Case back made of a ceramic and the use of radio-controlled timepiece of the bottom cover FIELD

The present invention discloses a bottom cover sheet and the use of radio-controlled timepiece of the bottom cover (aka: Table atom), in particular made of a ceramic case back and the use of radio-controlled timepiece of the bottom cover (Table atom).

Background technique

Wave form (also known as atoms table), which is built by a wristwatch radio receiver and antenna, receives the "standard time" wave emitted by the towers, acquisition time and calendar data, can automatically correct the time and date watch. The standard time signal is used in high-precision cesium atomic watches theory, one hundred thousand in a second error, a very high degree of accuracy, belonging to the new favorite watch industry, much-favored. However, the prior art wave form (atomic clock) of the case are mostly made of stainless steel, in use, likely to cause the shield to the "standard time" radio wave signal emitted tower, thus affecting the sensitivity of the received signal.

technical problem

For the above-mentioned prior art multi-wave form is stainless steel shell, likely to cause the shield to the "standard time" radio wave emitted tower, thus affecting the disadvantages of its use, made according to the present invention provides a novel ceramic table bottom cover and the bottom cover employed wave form, which comprises a bottom cover fixed together, the outer ring and the inner ceramic core metal, ceramic inner core portion can wristwatch good signal penetration, effective to solve the above problem.

Technology Solutions

Aspect of the present invention to solve the technical problems is: caseback made of a ceramic, a metal case back comprises an outer ring and a ceramic inner core, said outer annular metal, a ceramic and a metal inner core the outer shape of the inner hollow portion coincides with the ceramic core metal outer ring fixedly mounted together.

The present invention also provides a use of the above-described case back made of a ceramic wave form, comprising a watch movement and a housing disposed within the watch case, the watch case is attached to the bottom of the bottom cover sheet, comprising the caseback ceramic outer and inner metal core, said outer annular metal, a ceramic and a metal core inside the outer shape of the hollow portion coincides with the ceramic core metal outer ring fixedly mounted together.

The present invention to solve the technical problem using technical solutions which further comprises:

The ceramic core by the metal outer glue bonded together.

On the interior of the hollow portion of the outer ring is provided with a metal and a ceramic core a shape match step.

Beneficial effect

The beneficial effects of the present invention are: the present invention uses a ceramic core with a metal outer structure, not only the reception signal intensity wristwatch penetration, but which also has a wear-resistant, high melting point, electrical insulation properties good bit like, particularly the present invention has excellent chemical stability and oxidation resistance, while having high strength at high temperatures, heat resistance, corrosion-resistance characteristics, still at a high temperature of the acid and neutral corrosive substances, can greatly increase the life of the watch.

Will now be further described in conjunction with the present invention do drawings and specific embodiments.

BRIEF DESCRIPTION

1 a perspective schematic structural diagram of FIG novel caseback practical.

FIG 2 of the present invention an exploded schematic view of the state of the bottom cover sheet.

FIG 3 is a schematic cross-sectional structure of the new utility caseback.

FIG, 1-metallic outer ring, a ceramic inner core 2-, 3- steps.

Preferred embodiment of the present invention.

Embodiment of the present invention, a preferred embodiment of the present embodiment, the same or similar to other embodiments, all within the protective scope of the invention where the novel principle and basic configuration of the present embodiment.

See Figure 1, Figures 2 and 3, the present invention mainly as a table-cover structure, the bottom cover sheet including a ceramic metal inner core and an outer ring 1 2, in this embodiment, the metal outer race 1 can be made of materials such as stainless steel, a metal ring-shaped outer ring 1 as a whole, an intermediate portion in a hollow shape, the same shape of the hollow portion 2 between the inner core and the ceramic wherein the ceramic inner core 2 can just fitted in the outer metal a hollow intermediate portion, the overall shape of the ceramic core 2 may be circular or square or other geometric shapes, preferably circular. In this embodiment, the inner core 2 by ceramic glue on the metal outer ring 1, the specific embodiments, other processes may be employed to secure the two together.

Please key 3 Referring to the drawings, the present embodiment is provided with a ceramic core corresponding to the second step on the metal outer ring 3, the ceramic core 2 when subjected to external pressure, and without departing from the metallic outer ring 1, so that its stability is better.

The present invention also provides a wave form, comprising a watch movement and a housing disposed within the watch case, the basic configuration of the radio clock wristwatch prior art, except that, in the present invention, the wave form of the above-described bottom cover of the bottom cover. In the present invention, the bottom cover and the case can usually be installed with the following three methods, a bottom cover is provided with screw ports into a spin threadably; 2, the bottom cover is pressed down, and the table snapped together shell; 3, the bottom cover are provided four screw holes by screws in the case of small, it is connected to the above embodiment, the bottom cover may also be used in other ways mounted together with the case.

The present invention uses a ceramic core with the structure of the metal outer ring, not only the reception signal intensity wristwatch penetration, but which also has a wear-resistant, high melting point, a little good electrical insulation properties, in particular the present invention model has excellent chemical stability and oxidation resistance, while having high strength at high temperatures, heat resistance, corrosion-resistance characteristics, still neutral and acid etching material at high temperatures, can greatly increase the life of the watch.
