Embodiment Construction

[0007] attached figure 2 It is an application example of the present invention. In this example the thickness of the manhole cover 1 of the present invention is 20 mm. A double-layer hole 2 is drilled with a machine drill at the near edge, and the depth of the upper hole of the double-layer hole 2 is 14mm. Use a bolt 3 to pass through the double-layer hole 2 of the well cover 1 and the hole 6 of the inner eaves 4 of the well seat, and place The well cover 1 is connected with the well base 5, the thickness of the screw head of the bolt 3 is 9 mm, the length of the polished rod 7 of the screw is 55 mm, and the diameter of the screw is slightly smaller than the small hole 2 of the double hole of the well cover and the hole 6 of the inner eaves 4 of the well base diameter, the thickness of the inner eaves 4 of the well seat is 10mm, and the upper hole top of the well cover 1 is closed with an iron block with a thickness of 4mm. Well cover 1 is covered on the well base 5 to clos...

Abstract

The invention relates to a bolt-connecting anti-theft iron well lid device of a sewer, which is used for covering the well lid of the sewer. The existing iron well lid on the road surface is easy to be stolen, and people are easily hurt due to holes left in the road surface. For the existing seat-connecting anti-theft well lid device, the peripheral road surface needs to be drilled when the well lid is replaced, and an electric device is needed, thus being not economic and inconvenient. According to the invention, a bolt is used for connecting the well lid and a well base through a double-layer hole of the well lid and the inner edge hole of the well base, and the upper part of the hole is sealed by a metal block. When the well lid needs to the uncovered, only a tool is used for hooking an uncovering hole of the well lid and the well lid is lifted upwards and rotated by 180 degrees. When the well lid needs to be replaced, only the metal block needs to be pried, the bolt is detached, the electric tool is not needed, and the road surface is not destroyed. A theft does not take risk of steeling the well lid as the well lid is troublesome to take and can make much loud noise, such that the well lid can be kept, and the bolt-connecting anti-theft iron well lid device is particularly applicable to protecting large and medium well lids.

Description

Technical field [0001] The invention relates to a bolt-connected sewer anti-theft iron manhole cover device, which is a cover for sealing a sewer well. Background technique [0002] At present, the iron manhole covers on the road are easy to be stolen, and the holes left on the road are easy to hurt people. In order to prevent the well cover from being stolen, a joint-type anti-theft well cover device has recently appeared on the road. Also will use electric equipment, very uneconomical and convenient. This is a problem that should be solved. Contents of the invention [0003] The invention provides people with a bolt-connected sewer anti-theft iron manhole cover device, which can prevent theft when used, and is economical and convenient to replace the cover. [0004] The technical scheme of the present invention to solve the technical problem is: use the method of machine drilling to make a double-layer hole at the edge of the well cover, and drill a through hole on th...
