[0021] See also Figure 1-4 , the utility model provides a technical solution:

[0022] A protective shell structure for a sound and light alarm comprises a protective shell 1 and a fixing plate 9. A sound and light alarm body 5 is arranged on the top of the fixing plate 9. A sound part 11 of the sound and light alarm is arranged on one side of the sound and light alarm body 5. The sound part 11 of the sound and light alarm is located inside the protective shell 1. The bottom of the fixing plate 9 is bonded to the inner bottom of the protective shell 1 by waterproof glue. A through hole 7 is provided on one side of the top of the protective shell 1. A light part 6 of the sound and light alarm is arranged at the through hole 7. The bottom of the light part 6 of the sound and light alarm is connected to the top of the sound and light alarm body 5. A sound-transmitting hole 4 is provided on one side of the protective shell 1. A blocking ring 3 is provided on the outer surface of the sound-transmitting hole 4. The inner side surface of the blocking ring 3 is in the same horizontal plane with the front end of the sound part 11 of the sound and light alarm. An adhesive ring 8 is provided on the outer surface of the through hole 7 and located on the top of the sound and light alarm body 5. The outer surface of the adhesive ring 8 is connected to the inner surface bottom of the protective cover 2 by waterproof glue. The interior of the protective cover 2 is the light part 6 of the sound and light alarm.

[0023] Furthermore, threaded holes are provided on both sides of the top of the fixing plate 9, and fixing ears are provided on both sides of the bottom of the sound and light alarm body 5, and the fixing ears are connected to the threaded holes by fixing bolts.

[0024] Specifically, the utility model has a fixing plate 9 connected to the inner bottom of the protective shell 1 by waterproof glue. The size of the fixing plate 9 is larger than the size of the sound and light alarm body 5, so the fixing ears on both sides of the sound and light alarm body 5 will be located on the top of the fixing plate 9, so that the fixing ears can be fixed to the fixing plate 9 by fixing bolts.

[0025] Furthermore, a waterproof and breathable membrane 10 is provided on the inner surface of the protective shell 1 .

[0026] Specifically, the provision of the waterproof breathable membrane 10 can make the protective housing 1 waterproof to a certain extent, thereby preventing the sound and light alarm from being affected by rain for a long time after being installed outdoors, thereby causing internal damage.

[0027] Furthermore, the material of the protective cover 2 is tempered glass.

[0028] Specifically, the tempered glass allows the light generated by the optical part of the sound and light alarm to pass through, thereby preventing the problem in the existing protective structure that the light cannot be allowed to pass through after the sound and light alarm is protected.

[0029] Furthermore, a sealing ring is provided at the connection portion between the protective cover 2 and the protective shell 1 .

[0030] The sealing ring can seal the connection between the protective cover 2 and the protective shell 1 to prevent rainwater from entering the interior of the protective shell 1 through the gap at the connection.

[0031] It should be noted that, in the utility model, a protective shell structure of a sound and light alarm is provided, in which the outer surfaces of the sound and light alarm body 5 and the sound part 11 of the sound and light alarm are protected by a protective shell 1, and in order to allow the sound to pass through the protective shell 1, a sound-permeable hole 4 is provided at the contact point between the protective shell 1 and the sound part 11 of the sound and light alarm, and a blocking ring 3 is provided around the sound-permeable hole 4. The setting of the blocking ring can prevent a part of water from entering the interior of the protective shell 1 through the sound-permeable hole 4.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
