Deflection type astronomical watch device for sunshine heat dissipation by pressure

Abstract

The invention discloses a deflection type astronomical watch device for sunshine heat dissipation by a pressure. The structure comprises a sunshine heat dissipation hole air compression device, a watchband connecting block, a watchband, a fixing buckle and a fixing ring. The sunshine heat dissipation hole air compression device comprises an astigmatism concave sheet, a dial body, an air compression device and an adjusting dial needle. The device has the following benefits: sunshine can be deflected by the astigmatism concave sheet, so that the sunshine entering the dial is spread out, the phenomenon of focusing is avoided, the heating degree of the surface is effectively reduced, the dial is amplified, and the observation effect is improved; the pressure between the dial and a protective shell is increased by an air bag and a sealing rubber plate, so that sea air is prevented from invasion; the hot air flow is changed into cold air before entering by a straight plate, an upper skew plate, a transverse plate and a lower skew plate, so that heat of the watch can be dissipated; the contact area of the watch and the arm is reduced by a heat dissipation device, and the arm is effectively prevented from sweating.

Description

technical field [0001] The invention relates to the field of watches, in particular to an astronomical watch device with deflection type pressure astigmatism. Background technique [0002] An astronomical watch refers to a small timer used for astronomical time measurement or marine timing. It combines power machinery and many transmission machinery as a whole, and uses several sets of gear trains to slow down the movement of the wheel to keep it constant. A constant speed, which can represent astronomical phenomena and timekeeping. [0003] However, when the astronomical watch is used in navigation, due to the weather and climate of the ocean, its air temperature is relatively high, which makes the watch heated, which easily causes the internal metal parts to expand to varying degrees, making it go wrong or even stuck, and Because the sea breeze contains salt, it is easy to change the lubricating oil inside, reducing the lubricating effect, resulting in a greatly shortened...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a deflected pressure astigmatism astronomical watch device to solve the problem that the air temperature of the current astronomical watch is relatively high due to the weather and climate of the ocean when it is used in navigation. If the watch is heated, it is easy to cause the internal metal parts to expand to different degrees, causing errors or even jamming in the travel time, and because the sea breeze contains salt, it is easy to change the internal lubricating oil, reducing the lubricating effect and causing astronomical The oscillation period of the balance wheel in the watch is greatly shortened, accompanied by the problem of rapid watch sound
