Description

Technical Field

[0001] This utility model relates to the field of sound and light alarm technology, specifically to a waterproof and dustproof sound and light alarm. Background Technology

[0002] Audible and visual alarms are warning devices widely used in security, fire protection, transportation, industrial control and other fields. They use high-decibel sirens and high-brightness flashing lights to issue eye-catching audio-visual alarms to people in emergency situations, so as to achieve the purpose of reminding, warning and guiding people.

[0003] In complex industrial and outdoor applications, alarms are often exposed to harsh environments such as rain, dust, and humidity. Therefore, stringent requirements are placed on their waterproof and dustproof performance. Currently, most waterproof audible and visual alarms on the market use sealing rings at the joints of the housing, such as an O-ring between the top cover and the housing. However, this sealing method has some inherent drawbacks: First, after long-term use, the sealing rings are prone to aging, deformation, or wear, leading to a decrease in sealing performance. Moisture and dust can easily penetrate the device from the joints, causing short circuits or damage to internal electronic components. Second, traditional sealing structures require high production precision and skilled operator handling during assembly; uneven or misaligned sealing rings can directly create waterproofing leaks.

[0004] Furthermore, the installation methods for existing alarms are typically quite limited. When users need to change the installation location or orientation, additional adapters are often required, which not only increases the complexity of installation but also raises operating costs and lacks flexibility.

[0005] Therefore, there is an urgent need for a waterproof and dustproof audible and visual alarm device that is reasonably designed, has more reliable sealing performance, and offers a variety of flexible installation methods to solve the above-mentioned problems in the existing technology. Utility Model Content

[0006] The present invention provides a waterproof and dustproof audible and visual alarm to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A waterproof and dustproof audible and visual alarm includes a housing, a top cover on the top of the housing, a bottom cover on the bottom of the housing, a lampshade on the top of the top cover, an alarm on the front side of the housing, and a mounting base on the bottom of the bottom cover. The front side of the housing has a mounting cavity in which the alarm is fixedly installed. A first sealing groove is formed at the edge of the top cover, and a first sealing platform is formed at the bottom of the lampshade that mates with the first sealing groove. A second sealing groove is formed at the top edge of the housing, and a second sealing platform is formed at the bottom of the top cover that mates with the second sealing groove. A third sealing groove is formed at the top edge of the bottom cover, and a third sealing platform is formed at the bottom of the housing that mates with the third sealing groove.

[0009] Preferably, the mounting base includes a vertical mounting base and a side mounting base. The bottom of the vertical mounting base is provided with a first mounting plate horizontally, and one side of the side mounting base is provided with a second mounting plate vertically. Both the first mounting plate and the second mounting plate are provided with multiple mounting holes.

[0010] Preferably, the first sealing platform, the second sealing platform, and the third sealing platform are respectively embedded in the first sealing groove, the second sealing groove, and the third sealing groove.

[0011] Preferably, the lampshade and the top cover, the top cover and the housing, and the bottom cover and the housing are all connected by threads.

[0012] Beneficial effects

[0013] The beneficial effects of this invention are as follows:

[0014] 1. By setting up a multi-seal structure in which the sealing platform and sealing groove interlock and cooperate with each other, the traditional independent sealing ring is replaced, which significantly improves the sealing reliability and durability of the lamp cover, top cover, housing and bottom cover. It effectively prevents moisture and dust from entering, achieves a higher level of waterproof and dustproof protection, and extends the service life of the product in harsh environments.

[0015] 2. By providing optional vertical and side-mounted mounting brackets, along with different mounting plates, the product's installation flexibility is greatly enhanced. Users can adapt to different installation needs without additional accessories, simplifying the installation process and reducing usage costs. Attached Figure Description
