The invention provides a key for a well cover electronic lock and a well cover electronic lock assembly. The key of the manhole cover electronic lock includes a main body; the main body has an elongated insertion rod part extending along the first direction; the key also includes a push rod and a telescopic part, the push rod is slidably arranged in the insertion rod part along the first direction, and the telescopic part can move It is stored in the inserting rod part; when the push rod moves along the first direction, the telescopic part can be pushed to extend beyond the outer peripheral surface of the inserting rod part. The manhole cover electronic lock assembly includes the manhole cover electronic lock and the key, and the key socket of the manhole cover electronic lock is a through hole penetrating through the manhole cover electronic lock. The key provided by the invention realizes the switching between the unlocking function and the cleaning function through the shape change, effectively cleans the manhole cover electronic lock, and ensures the unlocking effect and the water-repelling and sewage-discharging effect.
Description
technical field [0001] The invention relates to the technical field of locks, in particular to a key for a manhole cover electronic lock and a manhole cover electronic lock assembly. Background technique [0002] In order to realize theft prevention, in addition to the original outer manhole cover, the existing wellhead also has an inner manhole cover inside the outer manhole cover. A manhole cover electronic lock is installed on the inner manhole cover. The manhole cover electronic lock is fixed at the center of the bottom of the inner manhole cover. The manhole cover electronic lock includes a fixed part and a rotating part. The fixed part includes a casing for locking with the inner manhole cover. At least three lock bars are swingably arranged on the circumferential position of the lock cylinder structure. After the rotating part rotates, the lock rod can move radially and retractably along the inner manhole cover. When the lock rod protrudes from the outer circumferenc...
