Description
Technical field
The utility model is related to a kind of cistern devices, more particularly to a kind of cubic water tank manhole cover.
Background technology
Currently, the scale with urban skyscraper is increasing, secondary water-supply facility is increasingly valued by people,
Existing secondary water-supply equipment is typically to use cistern water supply, especially cubic water tank.When will be arranged above water tank for maintenance
By manhole and manhole cover, existing manhole cover is typically that an individual lid is connect by hinge with manhole, and all
Convex relative to tank top, there are following hidden dangers for such structure design:1, the manhole cover protruded is easy will be in water
The service personnel of case top surface walking trips, and there are security risks;2, stress is more concentrated at hinge, when load-bearing is larger, hinge
It is easily deformed damage, causes manhole cover normally-open.
Therefore those skilled in the art are dedicated to developing a kind of cubic water tank manhole cover embedded, intensity is high.
Utility model content
In view of the drawbacks described above of the prior art, it is embedded that the technical problem to be solved by the utility model is to provide one kind
The high cubic water tank manhole cover of formula, intensity.
To achieve the above object, the utility model provides a kind of cubic water tank manhole cover, including upper cover, lower cover, inside
Supporting rack, the interior shelf include top reinforcing rib, midfoot support bar, lower support frame;Described top reinforcing rib etc.
Away from being fixed on the upper cover inner wall;The lower support frame is fixed on the lower cover inner wall;Midfoot support bar both ends point
It is not connected to the top reinforcing rib and the lower support frame.
The lower cover is the cylinder-like structure of open top end;The upper cover surrounding bends inwards to form the side of double-layer structure
The wing;The lower tops are provided with the card slot worked in coordination with upper cover flank bottom;The upper cover is clamped with the lower cover
Together, a cavity is formed therebetween.
The lower support frame is the honeycomb structure of regular hexagon;The lower support frame side is inscribed in described
The lower cover inside bottom surface is fixed in lower cover inside sidewalls, the lower support frame bottom surface;The top reinforcing rib, it is described in
Portion's supporting rod, the bottom support frame constitute the integral frame structure that side is triangular structure.
It is provided with the lock for being embedded in the upper cover at four avris wing top center of the upper cover;The upper cover top center
It is provided with embedded handle;The lower cover side-wall outer side is provided with a circle sealing rubber ring.
The utility model has the beneficial effects that:The utility model is simple in structure, and intensity is high, good integrity, be unlikely to deform by
Damage, while it can be embedded in water tank, it avoids being tripped by manhole cover when tank top is walked when maintenance.
Description of the drawings
Fig. 1 is the structural schematic diagram of one specific implementation mode of the utility model.
Fig. 2 is the structural schematic diagram of Section A-A in Fig. 1.
Fig. 3 is the structural schematic diagram of the bottom support frame.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1 to Figure 3, a kind of cubic water tank manhole cover, including upper cover 1, lower cover 2, interior shelf 3, inside branch
Support 3 includes top reinforcing rib 31, midfoot support bar 32, lower support frame 33;Top reinforcing rib 31 is equidistantly fixed on upper cover 1
Inner wall;Lower support frame 33 is fixed on 2 inner wall of lower cover;32 both ends of midfoot support bar are connected to top reinforcing rib 31 under
Portion's braced frame 33.
Lower cover 2 is the cylinder-like structure of open top end;1 surrounding of upper cover bends inwards to form the flank 11 of double-layer structure;
2 top of lower cover is provided with the card slot 4 worked in coordination with 11 bottom of upper cover flank;Upper cover 1 is connected together with lower cover 2, the two it
Between formed a cavity.
Lower support frame 33 is the honeycomb structure of regular hexagon;33 side of lower support frame is inscribed in 2 side of lower cover
On the inside of wall, 2 inside bottom surface of lower cover is fixed in 33 bottom surface of lower support frame;Top reinforcing rib 31, midfoot support bar 32, bottom branch
Support frame frame 33 constitutes the integral frame structure that side is triangular structure.
It is provided with the lock 5 for being embedded in upper cover 1 at the four avris wing of upper cover, 11 top center;1 top center of upper cover is provided with
Embedded handle 6;2 side-wall outer side of lower cover is provided with a circle sealing rubber ring 7.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, it all should be in the protection domain being defined in the patent claims.
