The invention discloses a cable well cover plate structure which is characterized in that limiting pieces are arranged at multiple positions of the connecting position of a bearing frame and an assembling frame, each limiting piece is provided with a first protrusion and a second protrusion, and a well cover is provided with clamping grooves which are matched with the forming positions of the limiting pieces and can clamp the limiting pieces; a first protruding block and a second protruding block are arranged at the opening end of the clamping groove in a protruding mode towards the interior of the clamping groove, the first protruding block and the second protruding block are oppositely arranged, the well lid falls to be assembled to the well mouth frame, the first protruding block in the clamping groove abuts against the first protrusion on the limiting piece, the well lid deviates towards one side, the first protruding block and the first protrusion continue to fall to be staggered, and the well lid is assembled to the well mouth frame. The second protruding block abuts against the second protrusion, so that the well lid returns to the original position, and the limiting piece and the clamping groove form an inverted buckling structure capable of preventing the well lid from being easily opened. The invention further discloses an opening device of the cable well cover plate, the opening device is provided with a mechanical anti-theft structure, an operator can easily open the cable well cover plate through a simple tool, the labor intensity is reduced, and the operation efficiency is improved.
本发明公开了一种电缆井盖板结构,在承载框和装配框相接连位置的多处设有限位件,限位件设有的第一凸起和第二凸起,井盖设有与限位件开设位置相适配且能够对限位件进行卡持的卡槽,卡槽的开口端向卡槽的内部分别凸设第一凸起块和第二凸起块,第一凸起块与第二凸起块相对而设,其中:井盖下落装配至井口框架,卡槽内的第一凸起块抵压限位件上的第一凸起,使井盖朝一侧偏移,第一凸起块与第一凸起继续下落错开,第二凸起块抵压第二凸起,使井盖回归至原位置,限位件和卡槽形成能够防止井盖被轻易打开的倒扣结构。本发明还公开了一种电缆井盖板的开启装置,具备机械防盗结构,作业人员通过简单工具即可轻松打开,降低劳动强度,提升作业效率。
