Abstract
The utility model relates to a remote-control projecting clock, which is composed of a remote-control device, a projecting device and an electronic clock, wherein, the remote-control device and the electronic clock are arranged in a box body; a nixie tube is arranged at the position of a display window of a clock at the upper surface of the box body; an upright rod with a universal joint is arranged on the box body; the end part of the is provided with a projecting lens which is positioned above the nixie tube; time can be displayed on any walls convenient to watch by that the position of the projecting lens is adjusted. The utility model has the advantages of convenient operation, and is particularly be suitable for night.
Description
The utility model is a kind of time set, particularly a kind of remote control projection clock.
Existing time set, as wrist-watch, wall clock etc., all not too convenient when using night, at first to turn on electric light, and then viewing time, owing to be the viewing time at night, its sharpness is also influenced.
The utility model purpose is a kind of remote control projection clock of being convenient in the use at night of design.
The utility model is realized as follows, described projection clock is made up of telechiric device, projection arrangement and electronic clock, telechiric device and electronic clock are located in the box body, time shows it by the high brightness charactron, charactron is located at the clock display window place of cartridge upper surface, be provided with a vertical rod that has the direction joint on box body, the end of vertical rod is provided with projection lens, and camera lens is positioned at the top of charactron; Described telechiric device and electronic clock comprise: digital circuit, charactron, single-chip microcomputer, infrared receiving circuit, circuit and control knob give the correct time.Wherein charactron and digital circuit link, and digital circuit and single-chip microcomputer (model is 2051) link, and single-chip microcomputer links with infrared emission circuit, charactron, control knob and the circuit that gives the correct time respectively.
During use, infrared remote control switch is passed to infrared receiving circuit with signal, current time when charactron shows, through projection lens with time showing on metope.
The utility model is easy to operate, and pot life is shown on any one metope of being convenient to watch, is particularly suitable for using night.
Below in conjunction with accompanying drawing the utility model is described further.
