Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of security alarm device, especially to a security alarm device with protective structure. BACKGROUND

[0002] The security alarm device is a system for preventing and responding to illegal intrusion, fire, gas leakage and other security threats. It is usually composed of sensors, controllers, alarms and other security devices, which can monitor and record specific areas in real time. When the system detects abnormal conditions, it will automatically trigger the alarm device to notify relevant personnel for handling.

[0003] Chinese patent publication No. CN215935291U discloses a security alarm device with protective structure, which comprises a security alarm device body, an induction probe is arranged on the front surface of the security alarm device body, an alarm sound is arranged at the top end of the security alarm device body, and heat dissipation channels are formed on both sides of the security alarm device body. The security alarm device is provided with a screen mesh mounting frame, a dustproof screen mesh, a positioning base and an installation positioning block. In actual use, the dustproof screen mesh can effectively block dust and other impurities, preventing them from entering the interior of the security alarm device body through the heat dissipation channels. This effectively solves the problem that most existing security alarm devices do not have protective structures, and dust easily enters the interior of the security alarm device through the heat dissipation openings during long-term use, thereby shortening the service life of the internal components of the security alarm device. The structure of the utility model is simple and easy to popularize.

[0004] However, the above technical solution has the following disadvantages: when fixing and installing the screen mesh mounting frame, the operator needs to hold and position the frame while operating the knob to rotate the threaded rod for fixation, which is not convenient for fixing operation and is also dangerous when the equipment is placed at a high place. Moreover, the device relies only on natural heat dissipation of the equipment for heat dissipation, and when the temperature is high due to external environmental factors such as weather, the heat dissipation efficiency is not enough, which reduces the service life of the internal components of the equipment. UTILITY MODEL CONTENTS
