from PyQt5.QtCore import QTimer

app = QApplication([])

msg_box = QMessageBox()
msg_box.setWindowTitle("弹出消息")
msg_box.setText("这是一个弹出消息的示例")

timer = QTimer()
timer.setInterval(3000)  # 设置为3秒钟

def show_message():
    msg_box.show()

timer.timeout.connect(show_message)

timer.start()

app.exec_()
