Abstract

The invention particularly discloses a device applied to locking and opening a well lid lock and stably keeping. The device comprises a lock shell, wherein the lock shell is provided with a main shaft and a bidirectional corner electromagnet, wherein the bidirectional corner electromagnet drives an electromagnet shaft in the bidirectional corner electromagnet to rotate; the lower end of the electromagnet shaft is connected with a connection cover; the connection cover is connected with a chuck connection rod; the chuck connection rod is provided with a top block; the lock shell is provided with a positioning pin for positioning a rotary position of the chuck connection rod; the top end of the main shaft is matched with a rotary table and the bottom end of the main shaft is matched with a chuck; a notch is formed in the outer edge of the chuck; the notch is matched with the chuck connection rod; an annular opening is formed in the inner side of the chuck; the annular opening is matched with a limiting pin fixed on the lock shell. The device disclosed by the invention is simple in structure and the aim of unlocking or locking the well lid lock is realized through the corner electromagnet; the two states can be stably kept due to the characteristics of the corner electromagnet.

Description

technical field [0001] The invention relates to a well cover locking device, in particular to a device for locking, opening and stably maintaining a well cover lock. Background technique [0002] There are a lot of underground pipeline manhole covers on urban roads. To prevent people from stealing manhole covers or illegally entering the wells, locks are often added to the back of the manhole covers. When the lock is in the open or closed state, it is critical to maintain the state. The traditional way is to use the spring top ball, but it is very unstable and easy to be damaged under strong impact; the push-pull electromagnet has a small telescopic distance due to the shape limitation. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, to provide a device with simple structure, easy to use, which can stably maintain the locked or unlocked state of the manhole cover, which is applied to the locking, opening and stable m...
