Description

Technical Field

[0001] The utility model relates to a gas alarm, in particular to a gas alarm with a power quick-connect module. Background Art

[0002] Gas alarms are mainly used to detect combustible gases in the air and are commonly used in factories, gas stations, metallurgical plants, household gas alarms and other places. Gas leakage will have a significant impact on the property safety and life safety of the enterprise.

[0003] At present, gas alarms on the market are equipped with power cords by default when they leave the factory. The power cords are relatively short, and they often need to be rewired during use, especially in factories and metallurgical plants. When gas alarms are replaced (lifespan is 2 to 3 years) or during periodic calibration, they need to be disassembled in batches. At the same time, for on-site safety, the same number of alarms need to be installed, and the power cords need to be frequently disassembled and installed one by one, which results in a large workload and low efficiency. Calibration agencies and metrology calibration personnel need to frequently disassemble and install power cords when calibrating alarms, which results in low calibration efficiency and a safety risk of electric shock. Therefore, further improvements are needed on this basis. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a gas alarm with a power quick-connect module, which includes an alarm body 1, the alarm body 1 is provided with a display screen 2, and the interior of the alarm body 1 is provided with a 220V power terminal 6, a 24V power terminal 7, an audible and visual alarm device terminal 8 and a sensor probe wiring port 9, the 24V power terminal 7 is connected to its quick-connect module socket 5 through a connecting cable 10, and the alarm body 1 is connected to the audible and visual alarm 3 through the audible and visual alarm device terminal 8, and the alarm body 1 is connected to the sensor probe 4 through the sensor probe wiring port 9.

[0006] Furthermore, a power quick-connect module plug 11 is connected to the quick-connect module socket 5 , and one end of the power quick-connect module plug 11 is connected to a power supply line 12 .

[0007] Furthermore, the quick-connect module socket 5 is provided with a socket nut 5-1, the power quick-connect module plug 11 is provided with a plug bolt 11-1, and the socket nut 5-1 and the plug bolt 11-1 are bolted to each other.

[0008] Furthermore, the alarm body 1 is composed of an upper shell and a lower shell, and both the upper shell and the lower shell are made of die-cast aluminum shells, and a sealing ring is provided at the joint between the upper shell and the lower shell.

[0009] Furthermore, the sensor probe 4 and the quick-connect module socket 5 are both located below the alarm body 1 .

[0010] After adopting the above technical solution, the beneficial effects of the utility model are: the gas alarm has at least the following advantages:

[0011] 1. When installing a new alarm, you only need to install the plug part of the power quick connector on the power supply cable end, connect the plug part directly with the socket part equipped with the alarm, and then power on the operation, which improves the installation efficiency;

[0012] 2. When the gas alarm is replaced or periodically tested, simply unscrew the power quick connector to disconnect the power supply, and directly connect the plug part with the socket part of the spare alarm to power on, thereby improving the efficiency of alarm disassembly and assembly;

[0013] 3. During the calibration by the calibration agency, the calibration personnel only need to install the plug part of the power quick connector at the end of the power supply cable, directly connect the plug part with the socket part equipped with the alarm, and then power on for batch rotation calibration, which effectively improves the calibration efficiency and reduces the risk of electric shock when disassembling and assembling the power cord.
