Municipal mute anti-theft well lid

Abstract

The invention belongs to the technical field of municipal engineering well lids, and particularly relates to a municipal mute anti-theft well lid. The municipal mute anti-theft well lid comprises a well wall, an adjusting and position-clamping mechanism and a balance adjusting mechanism; and the balance adjusting mechanism is installed on a boss of the inner circle face of the well wall, and the adjusting and position-clamping mechanism is installed on the upper side of the balance adjusting mechanism. According to the well lid, the anti-theft function, the well lid height adjustment functionand the well lid balance adjustment function are achieved; clamping strips extending out of an adjusting shell adjusting groove can be inserted into an adjusting groove in the well wall, so that the function of limiting the up-and-down movement and the rotary movement of an adjusting shell and a top lid is achieved, and the beneficial effect that the well lid is prevented from being easily liftedis achieved; and the purpose of adjusting stretching and retracting of a clamping block is achieved by rotating an adjusting shaft through an auxiliary tool which is inserted into an adjusting shaft lock hole.

Description

Technical field [0001] The invention belongs to the technical field of municipal engineering manhole covers, in particular to a municipal silent anti-theft manhole cover. Background technique [0002] At present, the manhole covers used in municipal engineering are often circular iron covers, and the manhole covers are generally higher than the road surface. When the circular iron covers are crushed by cars for a long time, the circular iron covers will vibrate due to the unevenness of the well wall bosses. , and the vibration sound is loud, so it will cause damage to the car and the road surface, and cause sound pollution. In addition, the design and structure of the manhole cover is simple, and it is easy to be lifted and lost. [0003] The present invention designs a municipal silent anti-theft manhole cover to solve the above problems. Contents of the invention [0004] In order to solve the above-mentioned defects in the prior art, the present invention discloses a ...
