Abstract

The invention discloses an anti-theft lock inspection well lid capable of being mounted and dismounted through a special key only. The inspection well lid comprises an inspection well lid base (111), an inspection well lid body (211), a fixed rammer fixing screw and lid body inner bottom surface space long anti-theft transverse latch (311) on the inner bottom surface of the inspection well lid and the like. The inspection well lid can be widely embedded at an inspection well opening for an underground pipeline of the urban road facility for use after being matched and combined with a special key for a push-and-pull opening-and-closing anti-theft lock inspection well lid for use; by the aid of the inspection well lid, lid stealing can be effectively prevented, and the inspection well lid is beneficial to the urban road traffic safety and obvious in social benefit.

Description

technical field [0001] The invention discloses an anti-theft lock manhole cover which can be assembled and disassembled only by a special key, comprising a manhole cover base 111, a manhole cover cover body 211, fixed upsetting fixing screws on the inner bottom surface of the manhole cover, and an elongated anti-theft space in the bottom surface of the cover body Horizontal latch 311 etc. After the present invention is used in combination with the "special key for push-pull switch anti-theft lock manhole cover", it can be used as a manhole cover widely buried in underground pipelines of urban road facilities, which can effectively prevent theft of the manhole cover and is beneficial to urban road traffic safety , its social benefits are obvious. Background technique [0002] So far, there is no "theft-proof lock manhole cover that has only special key to assemble and disassemble" and "the special key for push-pull switch anti-theft lock manhole cover" supporting combination...
