Description
Technical field
The present invention relates to the well lid being easy to open.
Background technology
Lay a lot of pipeline below the road of city, be used for laying communication cable and optical cable, in order to construct and maintenance requirement,
Offer multiple Jiao Jing, needing optical cable construction or safeguard when, need to open the cover plate of Jiao Jing, in actual use,
After cover plate covers on well lid bearing, need to use special cover opening tool to be opened by cover plate, to carry out communication cable
With the maintenance of optical cable, and during the pipeline of actual optical cable and cable lays, workmen carries specialty opener can be non-
Normal is not convenient.
Summary of the invention
The problem existed for above-mentioned prior art, the present invention provides the well lid being easy to open, and this well lid need not pass through
Patent opener can be achieved with the unlatching of cover plate, and the pipeline that can be easy to carry out in constructor optical cable or cable puts construction.
To achieve these goals, the present invention provides a kind of well lid be easy to and open, and coordinates with it including circular cover plate
Round manhole cover bearing, bearing plate and L bracket, described well lid bearing has ring-shaped step, and the bottom of described cover plate offers
Circular groove, described bearing plate is arranged on the inside of described groove, the left end of described bearing plate with described ring-shaped step phase
Corresponding position is provided with the breach matched with edge in ring-shaped step in obtuse angle, and bearing plate has at the left part of its breach
The medial wall matched in clearance of extension, described extension and cover plate, described cover plate is corresponding described extension in the inside of groove
Position is fixedly installed for described extension carries out spacing spacing annulus, and it is right that the right-hand member of bearing plate extends close to cover plate
The position of side inwall, and and described spacing annulus between leave gap, the right-hand member top of described bearing plate pass through connecting rod and substrate
Connecting, described cover plate offers the through hole connecting described groove in the position of counterpart substrate, and described L bracket is fixedly installed on institute
Stating on the medial surface on the left of ring-shaped step, the upper end of L bracket is connected by bearing pin with bearing plate, bearing plate and L bracket
Junction point is 1/4th of the distance to its right-hand member to the distance of its left end.
In this technical scheme, by making the extension of bearing plate left end and spacing annulus phase separation, make bearing plate left end
Breach match with the interior edge of ring-shaped step, needs open cover plate time, it is only necessary to by making substrate move downward, base
During plate moves downward, the fulcrum that the upper end of L bracket rotates as bearing plate, the extension of the left end of bearing plate is the most permissible
The spacing annulus of tilting moves upward, and i.e. can realize the opening action of cover plate.Bearing plate plays lever in opening process
Effect, can be effectively saved under substrate and press through the external force applied in journey.This well lid can be easy to the unlatching of cover plate, it is possible to effectively
Reduce the labor intensity of the pipeline construction personnel of optical cable and cable.
In order to increase the load bearing stength of cover plate, described cover plate is cast iron plate.
In order to reduce resistance, the interior edge that described ring-shaped step matches with described breach is fillet structure.
Preferred as one, make described through hole for circle.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, cover plate, 2, well lid bearing, 3, ring-shaped step, 4, bearing plate, 5, spacing annulus, 6, extension, 7, recessed
Groove, 8, through hole, 9, breach, 10, substrate, 11, L bracket.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of well lid being easy to open, the round manhole cover bearing 2 that coordinates with it including circular cover plate 1,
Bearing plate 4 and L bracket 11, described well lid bearing 2 has ring-shaped step, and the bottom of described cover plate 1 offers the groove of circle
7, described bearing plate 4 is arranged on the inside of described groove 7, and the left end of described bearing plate 4 is corresponding with described ring-shaped step 3
Position be provided with in obtuse angle with in ring-shaped step 3 along the breach 9 matched, bearing plate 4 has at the left part of its breach 9 and prolongs
Long section 6, described extension 6 and the medial wall matched in clearance of cover plate 1, described cover plate 1 is corresponding described extension in the inside of groove 7
The position of 6 is fixedly installed for described extension 6 is carried out spacing spacing annulus 5, and the right-hand member of bearing plate 4 extends close to
The position of inwall on the right side of cover plate 1, and and described spacing annulus 5 between leave gap, the right-hand member top of described bearing plate 4 is by even
Bar is connected with substrate 10, and described cover plate 1 offers the through hole 8 connecting described groove 7, described L-shaped in the position of counterpart substrate 10
Support 11 is fixedly installed on the medial surface on the left of described ring-shaped step 3, and the upper end of L bracket 11 and bearing plate 4 pass through bearing pin
Connecting, the distance of the junction point of bearing plate 4 and L bracket 11 to its left end is 1/4th of the distance to its right-hand member.
In this technical scheme, by making extension 6 and the phase separation of spacing annulus 5 of bearing plate 4 left end, make bearing plate 4
The breach 9 of left end matches with the interior edge of ring-shaped step 3, when cover plate 1 opened by needs, it is only necessary to by making substrate to 10 times fortune
Dynamic, during substrate 10 moves downward, the fulcrum that the upper end of L bracket 11 rotates as bearing plate 4, a left side for bearing plate 4
The extension 6 of end i.e. can move upward with the spacing annulus of tilting 5, i.e. can realize the opening action of cover plate 2.Bearing plate 4 exists
Opening process plays the effect of lever, the external force that substrate presses through applied in journey for 10 times can be effectively saved.This well lid can be just
Unlatching in cover plate 1, it is possible to efficiently reduce the labor intensity of the pipeline construction personnel of optical cable and cable.
In order to increase the load bearing stength of cover plate 1, described cover plate 1 is cast iron plate.
In order to reduce resistance, the interior edge that described ring-shaped step 3 matches with described breach 9 is fillet structure.
Preferred as one, make described through hole 8 for circle.
