Abstract

The invention relates to a folded anti-theft well lid. The folded anti-theft well lid comprises a well lid body and a well ring; the well lid body consists of a first half side body and a second half side body which are hinged with each other; the outer side of the first half side body is hinged with the well ring; and the outer side of the second half side body is provided with an opening hole, so that the well lid body can be locked on the well ring by a lock which penetrates through the opening hole. Half or all the folded anti-theft well lid can be opened according to the actual requirements, and the folded anti-theft well lid is convenient to use.

Description

technical field [0001] The invention relates to a manhole cover, more specifically to a double-fold anti-theft manhole cover. Background technique [0002] Most of the existing well covers are monolithic structures, and the opening needs to turn over or remove the whole well cover. Since the manhole cover is generally made of cast iron, its own weight is heavy, so it is more laborious to open. Especially when observing the situation in the well, it is necessary to open the whole well cover, which is time-consuming and labor-intensive. To sum up, we need to design a manhole cover that can choose different opening sizes according to actual needs. Contents of the invention [0003] The object of the present invention is to provide a double-fold anti-theft well cover, which can be half or fully opened according to actual needs, and is easy to use. [0004] The technical solution of the present invention is: a double-fold anti-theft manhole cover, including a manhole cover b...
