Lock applied to intelligent well lid

Abstract

The invention discloses a lock applied to an intelligent well lid. The lock comprises a lock body, a rotating shaft is rotationally mounted on the lock body, one end of the rotating shaft downwards penetrates out of the lock body, the other end of the rotating shaft is located in the lock body, a shaft sleeve is formed at the other end of the rotating shaft, a connecting shaft is further rotationally mounted on the lock body, one end of the connecting shaft upwards penetrates out of the lock body, the other end of the connecting shaft is located in the lock body and inserted into the shaft sleeve in the axial direction, a radial through hole is formed in the shaft sleeve, a plug pin is arranged in the radial through hole in a penetrating mode, an inserting groove allowing the plug pin to be radially inserted is correspondingly formed in the end, in the shaft sleeve, of the connecting shaft, the radial through hole is internally provided with a compressed spring prompting the plug pin to extend out radially and be separated from the inserting groove, and the lock body is internally provided with a driving mechanism for driving the plug pin to overcome acting force of the compressedspring to move inwards radially and be inserted into the inserting groove. By adopting the structure, the lock is simple in structure, and not only can electric unlocking through a motor be achieved,but also mechanical unlocking through a key can be realized.

Description

technical field [0001] The invention relates to a lock, in particular to a lock applied to an intelligent manhole cover. Background technique [0002] In order to facilitate people to open the manhole cover in the well to realize escape, the related literature (publication number: CN 109954238 A) discloses a manhole cover escape device in the well and its use method, but most of the existing locks that can be applied to the manhole cover escape device have complicated structures , and usually can only be unlocked electrically, there is a singleness. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a lock applied to an intelligent manhole cover. The lock has a simple structure and can be unlocked both electrically by a motor and mechanically by a key. [0004] In order to achieve the above object, the present invention provides a lock applied to a smart manhole cover, which includes a lock body, on which a rotat...
