Temperature measuring device with voltage protection

The utility model discloses a temperature measuring device with voltage protection, which comprises a control cabinet, a temperature measuring instrument and a junction box, the control cabinet is sequentially connected with the junction box and an infrared temperature measuring instrument through a cable led out of the control cabinet, a voltage stabilizing module is arranged in the junction box, and the cable led out of the control cabinet comprises a power supply cable connected with the voltage stabilizing module. Therefore, the voltage output by the control cabinet is input to the infrared thermometer after passing through the voltage stabilizing module. According to the utility model, the voltage stabilizing module is installed in the junction box, so that the damage to the infrared thermometer under the condition that the power supply voltage is possibly unstable can be avoided at a lower cost, too much maintenance work is avoided in the subsequent use process, and in addition, the voltage stabilizing
