Specific embodiment
Embodiment 1
With reference to Fig. 1 ~ 3, a kind of flue manhole door that embodiment 1 provides, including pedestal 1, capping 2, door-plate 3 and spiral handle 4；
3 forward direction of door-plate covers pedestal 1, and passes through capping 2 and compress, and 2 center of capping is equipped with threaded hole 5；Spiral handle 4 includes bar portion 4.1,
4.1 one end of bar portion is silk end 4.2, and the other end is fixed with holding rod 4.3, and silk end 4.2 connect with threaded hole 5 and against door-plate 3；It is described
1 side of pedestal is equipped with articulated section 6, and opposite side is equipped with fixed part；It is hinged with articulated section 6 to cover 2 one end, the other end is with fixed part
Detachable connection；The door-plate 3 is equipped with seal groove 10 with 1 contact position of pedestal, and sealing material is equipped in seal groove 10.
The fixed part is crossette 8, and capping 2 one end far from articulated section 6 and crossette 8 are equipped with the through-hole overlapped, cover 2 and
Crossette 8 is by passing through the bolt 9 of through-hole to fix.
2 lower section of capping is equipped with strengthening rib strip 7.
The sealing material is rubber layer 11.
The rubber pad 11 is fixed in seal groove 10.
The holding rod 4.3 of spiral handle 4 is vertical with bar portion 4.1.
The operation principle of the present embodiment：
2 one end far from articulated section 6 of capping is Chong Die with the through-hole of crossette 8, and bolt 9 passes through through-hole realization fixation, then by spiral
The silk end 4.2 of handle 4 is threaded into hole 5, and silk end 4.2 is fixed with threaded hole 5, and during being screwed into, and silk end 4.2 is to door-plate 3
It moves and applies pressure against door-plate 3 to door-plate 3, door-plate 3 is pressed on pedestal 1, realizes the closing of manhole door；Above-mentioned mistake
Journey contrary operation can open manhole door.
3 lower section of door-plate is equipped with strengthening rib strip 7, it is possible to increase the intensity of door-plate 3.
Door-plate 3 is contacted by seal groove 10 with pedestal 1, seal groove 10 lid close door-plate 3 when have guiding role, while
Sealing material is equipped in seal groove 10, improves the sealing effect of manhole door.Preferably, sealing material selects rubber layer 11, no
Only there is good sealing effect, simultaneously because the elasticity of rubber layer, has cushioning effect to seal groove 10 and pedestal 1, prevent
1 compressive deformation of seal groove 10 and pedestal.
The rubber pad 11 is fixed（Such as the existing ways such as adhesion）In seal groove 10, when opening door-plate 3, rubber layer
11 will not fall off, reusable, without needing to change or reinstalling, reduce process.
The holding rod 4.3 of spiral handle 4 is vertical with bar portion 4.1, and silk end 4.2 is screwed into or back-outs threaded hole 5, can pass through rotation
Vertical bar portion 4.1 is realized, laborsaving and easy to operation.
