Abstract
The invention relates to a manhole cover, in particular to a sewer manhole cover. The sewer manhole cover comprises a shield body, a rotating device capable of making the shield body rotate, an anti-falling net, an inner ring seat and an outer ring seat. The outer ring seat is fixedly connected to a ground base. The inner ring seat is installed inside the outer ring seat in a sleeved mode and fixedly connected with the outer ring seat. The middle position of the inner side face of the inner ring seat is sunken outwards to form an annular sliding groove. A tooth form is machined at the bottom of the inner side face of the inner ring seat. A latch butt joint opening is downward formed in the top surface of the inner ring seat. The anti-falling net is arranged inside the inner ring seat. The shield body is arranged inside the inner ring seat in a sleeved mode. The shield body is provided with an unlocking hole. The lockpin head end of a latch is matched with the latch butt joint opening and located in the annular sliding groove. The rotating device is composed of a cross bar, a longitudinal bar and a gear, wherein the gear is fixedly connected to the bottom end of the longitudinal bar and matched with the tooth form. The sewer manhole cover is convenient to use, the anti-falling net can prevent a pedestrian from falling into a manhole after the shield body is moved away, the shield body is not stolen easily after being combined with the inner ring seat in a clamped mode and is not easily propped open in extreme weather, and the ground does not need damaging when the sewer manhole cover is mounted and dismounted.
Description
Technical field
The present invention relates to a kind of well lid, especially a kind of well cover for sewer.
Background technology
The well cover for sewer of current use is mostly and is directly pressed in sewer opening part, without the device of clamping, when running into extreme weather, as long heavy rain, when sewer rushes down big vast scarce capacity, well cover for sewer is easily backed down, and there is the risk of the sewer that drops, cause life danger when people walk in water.Current well cover for sewer is mostly cast iron in addition or ductile cast iron material is made, and like this one is that economic worth is higher, is easily stolen by some lawless persons; Two is that weight is large, takes off and installs inconvenience.
Summary of the invention
The present invention is intended to solve the problem, and provides a kind of well cover for sewer, and which overcome traditional well cover for sewer without drawbacks such as gripping mechanism, easily stolen, weight large installation inconvenience and easy generation displacements, its technical scheme adopted is as follows:
A kind of well cover for sewer, comprise: cover body, the tumbler that cover body rotates can be made, anti-drop net, interior ring seat and outer ring seat, described outer ring seat is fixed on the matrix of ground by expansion bolt, described inner ring cover for seat to be loaded in outer ring seat and by screw and outer ring seat Joint, described interior ring seat medial surface middle position is outwards recessed to form annular groove, described interior ring seat medial surface bottom position place is processed with one section of profile of tooth, the end face of described interior ring seat offers at least one locking bolt docking port downwards, described locking bolt docking port is connected with annular groove, described anti-drop net is held in interior ring seat, described cover body to be set in interior ring seat and to be positioned at above anti-drop net, described cover body offers the open keyhole of a longitudinal direction near its edge, described open keyhole is positioned at directly over profile of tooth, described cover body has the locking bolt with quantity such as locking bolt docking ports, described locking bolt is by body, block rubber and lock pin composition, described body and cover body Joint, described block rubber and lock pin are arranged in body, the tail end of described lock pin contacts with block rubber, its head end and locking bolt docking port match and are arranged in annular groove, described tumbler is made up of cross bar, vertical pole and gear, and described gear is fixed in vertical pole bottom, and described vertical pole and open keyhole match, and described gear and profile of tooth match.
On technique scheme basis, the vertical pole of described tumbler has the annular protrusion of a radial direction, annular protrusion bottom surface is equal to the distance of the tooth top of profile of tooth with cover body end face to the distance of gear teeth tips.
On technique scheme basis, described anti-drop net is made up of the spoke of several concentric annular rings and some radial direction distributions, and described spoke connects each concentric annular ring, and outermost annular ring has one and lacks limit, and described scarce limit and profile of tooth are in the same side.
On technique scheme basis, described anti-drop net is bolted in interior ring seat.
On technique scheme basis, the bottom surface of described cover body forms some supporting legs.
On technique scheme basis, described supporting leg is annular.
On technique scheme basis, described locking bolt docking port and locking bolt are three, and between adjacent locking bolt docking port, angle is 120 degree, and between adjacent locking bolt, angle is 120 degree.
Tool of the present invention has the following advantages: easy to use, anti-drop net can avoid cover body after removing pedestrian fall, cover body runs into extreme weather and is also not easily backed down after engaging with interior ring seat, installation and transportation are convenient, can prevent displacement, upset, due to interior ring seat and outer ring seat separable, in use the interior comparatively outer ring seat of ring seat is first damaged usually, now only need pull down interior ring seat changes new interior ring seat, dismantles, thus can not destroy ground without the need to external ring seat.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the invention will be further described:
As shown in Figures 1 to 7, a kind of well cover for sewer of the present embodiment, comprise: cover body 2, the tumbler 1 that cover body 2 rotates can be made, anti-drop net 3, interior ring seat 4 and outer ring seat 5, described outer ring seat 5 is fixed on ground matrix 6 by expansion bolt 50, described interior ring seat 4 to be set in outer ring seat 5 and by screw 40 and outer ring seat 5 Joint, described interior ring seat 4 medial surface middle position is outwards recessed to form annular groove 41, described interior ring seat 4 medial surface bottom position place is processed with one section of profile of tooth 42, the end face of described interior ring seat 4 offers at least one locking bolt docking port 43 downwards, described locking bolt docking port 43 is connected with annular groove 41, described anti-drop net 3 is held in interior ring seat 4, described cover body 2 to be set in interior ring seat 4 and to be positioned at above anti-drop net 3, described cover body 2 offers the open keyhole 20 of a longitudinal direction near its edge, described open keyhole 20 is positioned at directly over profile of tooth 42, described cover body 2 has the locking bolt 21 with quantity such as locking bolt docking ports 43, described locking bolt 21 is by body 22, block rubber 23 and lock pin 24 form, described body 22 and cover body 2 Joint, described block rubber 23 and lock pin 24 are arranged in body 22, the tail end of described lock pin 24 contacts with block rubber 23, its head end and locking bolt docking port 43 match and are arranged in annular groove 41, described tumbler 1 is made up of cross bar 10, vertical pole 11 and gear 13, and described gear 13 is fixed in vertical pole 11 bottom, and described vertical pole 11 matches with open keyhole 20, and described gear 13 matches with profile of tooth 42.
