Large electromechanical pointer clock

Abstract

The present invention relates to the movement structure, calendar display, clock face installation and rotating shaft structure. The movement structure consists of four parts including pulse stepped motor, pointer transmission wheel system, pointer setting mechanism and hour and day reporting trigger signal output mechanism. The minute wheel in backward design is set outside the back clevice assembly for saving space. The calendar display is a micro power consumption and large width one and the clock face is float installed with springs for lasting flatness. The rotating shaft structure is of self-lubricating corrosive and wear resistant material. The large clock of the present invention is not affected by power failure, whether and environment, and is corrosive, wear resistance, accurate, reliable and durable.

Description

technical field [0001] The invention relates to a large-scale electromechanical pointer clock, in particular to the needle-moving movement structure, calendar display, clock face installation and rotating part shaft structure material of a large electromechanical pointer clock. Background technique [0002] Generally, a clock whose pointer length and circumference radius is 0.5 meters or more is called a large clock. It is widely used in airports, stations, squares, banks, towers and other public places in various countries. The development of electronic technology has reformed the structure of traditional clocks and watches, but due to the limitations of electronic technology, the traditional mechanical structure of clocks and watches is still in use today. The manufacturing process of the needle movement is complex, the friction coefficient of the transmission is large, and there are problems such as easy corrosion, easy wear, and easy oil stagnation. In the case of high ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the technical problems existing in the existing large-scale pointer clocks, such as the large friction coefficient in the transmission system of the needle movement, easy to corrode, easy to wear, easy to produce oil stagnation, difficult to adjust the pointer, and to deal with power failure and instantaneous power failure However, it is necessary to improve the structure of the movement needle movement; the surface unevenness of the large clock face is affected by factors such as time, gravity, thermal expansion and contraction; there is a lack of micro-power large-scale applications for large-scale analog clocks Calendar display device, etc.
