Abstract

The utility model provides an inner sliding groove connection type anti-theft well cover, and relates to an anti-theft well cover for preventing a well cover of an urban inspection well from being stolen. The inner sliding groove connection type anti-theft well cover mainly solves the problem that at present, the well cover of the urban inspection well is easy to steal since the well cover is separated from a well base; the well cover is in shaft connection with the well base; and ash and soil easily enter a gap which is necessarily left at the joint of a lug of the well base and a lug of the well cover to guarantee a 120-degree opening caster angle of the well cover, which affects the opening caster angle of the well cover, and leads the well cover to rebound to injure a person. The inner sliding groove connection type anti-theft well cover adopts the structure that an inner sliding groove is formed on the lug of the well base; and the lug at the side edge of the well cover is connected with a shaft hole in the sliding groove of the well base through a connection shaft. The well cover is convenient to open, is opened to be positioned by tilting 120 degrees, and does not rebound so as to prevent injury accidents of people; when erected, the well cover exerts the effect of caution; no gap is left at the rear end of the joint of the well cover and the well base, so that silt cannot enter the groove; and a lock is additionally arranged between the well cover and the well base, so that single security and double security can be performed on the well cover as required.
