Description
The utility model relates to well lid, especially a kind of anti-stealing manhole cover and opener thereof.
Catch pit in the city, gasser, tap water well, fire-fighting well and cable shaft, sink hole etc. are equipped with well lid.These well lids mainly are made up of well lid and manhole cover base.At present, well lid and manhole cover base are separate type, and promptly well lid can take off from manhole cover base.Therefore, well lid to lose phenomenon very general.Cause personal injury to occur again and again after well lid is lost, influence the traffic safety in city.
The purpose of this utility model is to lose serious problem at various well lids, provides a kind of well lid and manhole cover base indissociable anti-stealing manhole cover.The opener of anti-stealing manhole cover is provided simultaneously.
The utility model is achieved in that anti-stealing manhole cover comprises well lid and manhole cover base.One side of well lid has the lug of a band pin shaft hole.Periphery is shaped on alveolus below the well lid.A microscler open hole is arranged on the well lid, and manhole cover base is flange shape.The axis pin base that one side of manhole cover base has a shape and well lid lug to coincide.Be processed with on the axis pin base and the corresponding pin shaft hole in well lid lug upper pin hole.In the pin shaft hole of axis pin base and lug bearing pin is housed.Manhole cover base is along circumferentially being furnished with reinforcing rib.
The well lid opener comprises a pull bar.The upper end of the pull bar horizontal handle vertical that is connected with pull bar.The lower end of the pull bar microscler block that adapts with the well lid open hole that is connected.
During use, the manhole cover base periphery is imbedded in the cement, its upper surface flushes with ground.Well lid is placed on the manhole cover base, and its lug falls into the axis pin base of manhole cover base.Insert in the pin shaft hole on well lid lug and the axis pin base bearing pin and the both sides that make bearing pin expose axis pin base, then with the bearing pin shutoff of cement with exposed portions serve.The rear pin shaft that thes cement solidifies can't take out from pin shaft hole, thereby well lid can't take off from manhole cover base, can prevent effectively that the stolen phenomenon of well lid from taking place.Only need during unlatching opener is inserted open hole, turn over an angle and upwards lift and get final product.
The utility model simple structure, manufacturing, easy construction, cost is low.
Fig. 1 is that master of the present utility model looks sectional view;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the front view of well lid opener;
Fig. 4 is the vertical view of Fig. 3.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, anti-stealing manhole cover comprises well lid 2, manhole cover base 3.Well lid 2 is rounded, the round boss that has an alveolus 4 with manhole cover base to match below.One side of well lid 2 has the lug 6 of a dress bearing pin 1.Be processed with pin shaft hole on the lug 6.Also have a long trough open hole 8 on the well lid 2.Manhole cover base 3 is flange shape, and its upper surface is shaped on the alveolus 4 that coincide with the well lid boss, along being circumferentially with reinforcing rib 9.Lug 6 corresponding sites with well lid 2 have an axis pin base 7 on the manhole cover base 3.Be processed with on the axis pin base 7 and lug 6 corresponding pin shaft holes.During installation, flange shape manhole cover base 3 is imbedded in the cement 5 along periphery, upper surface flushes with ground.Well lid 2 is covered on manhole cover base 3, and insert bearing pin 1 in both pin shaft holes, the bearing pin 1 that will expose axis pin base 7 with cement 5 is sealed and is got final product.Just can't take out after the cement that bearing pin 1 is solidified is sealed, thereby well lid 2 can only be opened, can not take off, can not lose.The situation after well lid is opened is represented in double dot dash line among Fig. 1.
