Abstract
The invention discloses a rotary type well lid anti-theft mechanism and an operation method. The anti-theft mechanism comprises a buried ring plate, wherein connecting arc plates are fixedly connectedto the inner ring of the buried ring plate, a limiting ring plate is fixedly connected to the inner ring of the connecting arc plates, and a supporting ring plate is fixedly connected to the bottom of the inner ring of the limiting ring plate in the annular direction. According to the rotary type well lid anti-theft mechanism, a supporting slip ring, movable notches, a fixing protective sleeve, the limiting ring plate, a hexagonal rotating rod body, a sliding sleeve, arc-shaped grooves, an elliptical disc, a movable limiting rod, a circular rotating rod, guide blocks, sliding blocks, a movingplate, a supporting plate, a sliding groove, returning springs, a guide groove, a limiting ring groove, a supporting ring plate and a positioning rod are arranged and used in a matched mode so that simple operation can be carried out on the anti-theft mechanism, so the opening speed of a well lid is faster, and the problem that when the well lid is opened, the anti-theft mechanism consumes a large amount of time due to the complex operation of the anti-theft mechanism, so that the well lid is opened inconveniently is solved.
Description
technical field [0001] The invention relates to the technical field of well covers, in particular to a rotary well cover anti-theft mechanism and an operation method. Background technique [0002] Manhole covers are defenses used to cover the deep wells on the road or at home to prevent people or objects from falling. They are generally divided into round and square. In terms of road administration in urban areas, round is generally used, because round manhole covers are not easy to tilt , can better protect the safety of pedestrians and vehicles. The use of a round shape is mainly due to the fact that the length of each diameter of the round manhole cover passing through its center is the same. No matter how it is rolled up, its diameter will be slightly wider than the wellhead below, and the manhole cover will not fall into the wellhead, which can better protect the safety of pedestrians and vehicles. There are many kinds of national standards for manhole covers, single-la...
