draw bolts meaning in English

吊装螺栓

And you see , for such a large house , there are very few servants , because master has never lived here much ; and when he does come , being a bachelor , he needs little waiting on : but i always think it best to err on the safe side ; a door is soon fastened , and it is as well to have a drawn bolt between one and any mischief that may be about
尽管谁都知道，盘子柜里有价值几百英镑的盘子，而且你知道，老爷不在这里长住，就是来住，因为是单身汉也不大要人服侍，所以这么大的房子，只有很少几个仆人。不过我总认为过份注意安全总比不注意安全好，门一下子就能拴上，还是拴上门，把自己和可能发生的祸害隔开为好。
