Description

Technical Field

[0001] The utility model relates to the technical field of alarm display equipment, in particular to a simple alarm light sign. Background Art

[0002] The light-emitting sign is a disk-type assembly structure with a photonic display. It is connected to an external bell (or sounder), power supply, and control buttons to form a flash alarm system. The instrument uses electrical contact input signals and is used in conjunction with various contact-type control and detection instruments in industrial automation control systems to monitor the operating status of various equipment and provide over-limit alarms.

[0003] Utility model patent number CN218918243U discloses a light-emitting sign alarm system. This system utilizes a light-emitting sign body with multiple primary alarm text display areas. Each of these primary alarm text display areas is illuminated by a warning light, enabling real-time alarm monitoring. However, in this implementation, the primary alarm text display area is mounted on a plate, making it difficult to disassemble, repair, and install. Therefore, a simplified light-emitting alarm sign was proposed to address this issue. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-4 A simple alarm light sign includes a housing 1, a mainboard 2 is fixedly connected to the housing 1, an LED board 4 is connected to the mainboard 2 through a pin, a mounting groove 10 is provided on the housing 1, the LED board 4 is arranged in the mounting groove 10, and a sign glass 3 is provided on the LED board 4.

[0023] In this application, a text layer is provided on the sign glass 3 to indicate the specific fault condition of the equipment, and the LED board 4 is used to display an alarm with light.

[0024] The nameplate glass 3 displays different fault conditions of the equipment through the engraving process. The base color of the nameplate glass is black, the display characters are white transparent paint, and the frame of the nameplate glass 3 is white transparent paint to ensure consistent light transmittance.

[0025] In normal state, the LED light is green. When the fault signal is transmitted to the main board 2, the corresponding LED board 4 lights up red or yellow.

[0026] The LED board 4 is connected to the mounting slot 10 on the main board 2 via pins, which facilitates the disassembly, maintenance and installation of the LED board 4 .

[0027] The housing 1 is also connected to a buzzer board 5 via pins.

[0028] In this application, when a fault signal is transmitted to the main board 2, the buzzer board 5 simultaneously sounds an alarm. When the alarm level is low, the buzzer alarm decibel number is low; when the alarm level is high, the buzzer alarm decibel number is high. In this way, multiple alarm display modes are achieved.

[0029] A card pressing frame 6 is also provided to limit the insertion depth of the card glass 3. A boss 11 is provided on the inner wall of the lower portion of the mounting groove 10 to limit the insertion depth of the LED board 4 or the buzzer board 5.

[0030] In this application, a character board pressure frame 3 is provided between the LED board 4 and the buzzer board 5, which is used to limit the insertion depth of the character board glass 3 while also supporting the character board glass 3; the boss 11 is located on the lower inner wall of the mounting groove 10, which is used to limit the insertion depth of the LED board 4 or the buzzer board 5.

[0031] The buzzer board 5 is also provided with a buzzer glass 9 for dust prevention.

[0032] A buzzer pressing frame 8 for supporting the buzzer glass 9 is further provided between the buzzer board 5 and the buzzer glass 9 .

[0033] The housing 1 is further provided with a quadrilateral glass pressing frame 7 for holding the nameplate glass 3 or the buzzer glass 9 . The upper end of the nameplate glass 3 or the buzzer glass 9 is arranged in the quadrilateral glass pressing frame 7 .

[0034] The quadrilateral glass frame 7 is connected to the housing 1 by screws.

[0035] In the present application, the device facilitates replacement of the nameplate glass 3 from the front.

[0036] Remove the mounting screws from the front and take off the quadrilateral glass pressing frame 7 to replace the signboard glass 3.

[0037] In the present application, the device facilitates replacement of faulty LED board 4 and buzzer board 5 from the front.

[0038] After disassembling the sign glass 3, the sign pressing frame 6 is removed to replace the faulty LED board. Since the vulnerable parts or components with low MTBF are designed on the LED board, they can be replaced as a whole with the LED board.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
