Description
Technical field
The utility model relates to well lid field, refers in particular to a kind of buffering type double-layered well lid.
Background technology
Well lid is the closure that leads to the top, access of underground installation, and the place of the communal facilitieies such as every installation tap water, telecommunications, electric power, combustion gas, heating power, fire-fighting, environmental sanitation all needs to install well lid.Along with the develop rapidly of China's economy, China's infrastructure construction welcomes again a new cycle, and the market demand of well lid in urban planning and road construction is huge.What well lid generally adopted is that composite drain cover adds anti-drop net, the anti-drop net time has been grown easy corrosion, often one throw the net and use the defect that intensity declines after several years, add that well lid is rolled and situation damaged or that lose happens occasionally, cause road and installation security to decline, therefore, the inventor makes further research this, develop a kind of buffering type double-layered well lid, this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of buffering type double-layered well lid, can greatly improve road safety is set.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of buffering type double-layered well lid, comprise base, upper main cover, Xia Zigai, described base is circulus, described lower son lid is middle to lower recess, described upper main cover soffit upwards caves in, and between upper main cover and lower son lid, forms a cavity, and the medium position of lower son lid depression is also provided with two arch projections and two protruding bolts hole, upper main cover upper surface offers slotted eye, is provided with arch projection in slotted eye, the outer wall of described base has outward extending side, and reinforcing rib between outer wall and side, on the inwall of base, be provided with some spacing preiections, the upper end of described spacing preiection expands gradually to lower end, the interior wall construction of described spacing preiection below is the shellring shape step that radius reduces successively from top to bottom, on bottom step upper surface, offer three uniform bolts hole in interval, the bolt hole of offering with the edge of lower son lid is corresponding, lower son lid is bolted in the step of the base bottom, described upper main cover is fixed on lower son and covers and closely cooperate with base, the side of upper main cover offers the groove matching with spacing preiection, the upper surface of upper main cover upper surface and base maintains an equal level.
Further, the overall structure of described well lid is circular or square.
Adopt after such scheme, the utility model compared with prior art, has the following advantages:
1), after upper main cover breakage, Xia Zigai throws away and can play a protective role;
2) between base and upper main cover, coordinate closely, steadily;
3) there is anti-theft function, solid and reliable;
4) can not produce lateral displacement and can be anti-skidding.
Brief description of the drawings
Fig. 1 is decomposing schematic representation of the present utility model;
Fig. 2 is the schematic rear view of Fig. 1 upper main cover;
Label declaration
Base 1, spacing preiection 11, upper main cover 2, slotted eye 21,
Lower son lid 3, arch projection 31, bolt hole 32, reinforcing rib 4.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
(the present embodiment is taking round manhole cover as example) as shown in the figure, a kind of buffering type double-layered well lid that the utility model discloses, comprise base 1, upper main cover 2, lower son lid 3, described base 1 is circular ring, lower son lid 3 is the disk of a centre to lower recess, and upper main cover 2 is the disk that a soffit upwards caves in, upper surface has protruding formula decorative pattern.
Wherein the first half of base 1 inwall is provided with two apart from one another by the spacing preiection 11 of 180 °, and the upper end of spacing preiection 11 expands gradually to lower end; The groove of offering with upper main cover 2 sides matches, and the diameter of upper main cover 2 is consistent with base 1 inner ring maximum gauge, and upper main cover 2, just cannot lateral rotation after spacing preiection 11 inserted bases 1.
The outer wall of base 1 has the reinforcing rib 4 between outward extending side and outer wall and side, and side and reinforcing rib 4, for sharing the pressure from upper main cover 2, contribute to the integrally-built reinforcement of well lid.
The interior wall construction of spacing preiection 11 belows is the shellring shape step that radius reduces successively from top to bottom, on bottom step upper surface, offer three uniform bolts hole 32 in interval, corresponding with the bolt hole 32 at the lower sub edge that covers 3, lower son lid 3 is bolted in the step of base 1 bottom.
The medium position of lower son lid 3 depressions is also provided with two arch projections 31 and two protruding bolts hole 32, passes arch projection 31 lower son lid 3 can be lifted with cleek; And the bolt hole 32 that the bolt hole 32 of projection is offered with upper main cover 2 is corresponding, with plum blossom anti-theft screw, upper main cover 2 is covered to 3 with lower son and be fixed together.
Upper main cover 2 is passing through after spacing preiection 11 inserted bases 1, be fixedly connected with lower son lid 3 with bolt, between upper main cover 2 and lower son lid 3, form an airtight cavity, this cavity is made up of the soffit depression of upper main cover 2, the depression of lower son lid 3 and notch cuttype step around, the existence of cavity can make to produce a cushion space between lower son lid 3 and upper main cover 2, in the time that upper main cover 2 is subject to excessive pressure damage, under the support of notch cuttype step, can not feed through to lower son lid 3, lower son lid 3 still can play protective action.
Upper main cover 2 offers two slotted eyes 21, is also provided with arch projection 31 in slotted eye 21, and its effect is identical with the arch projection 31 of lower son lid 3.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
