the manhole door plate is provided with a manhole door plate and a central shaft, wherein the central shaft is sleeved with a pressure beam and a handle in sequence, the handle is meshed with the central shaft through threads, and the handle is rotated and moved to enable the manhole door plate and the pressure beam to be mutually pressed for sealing;
the two ends of the swing arm are respectively hinged and fixed with the central shaft and the support, and the support is fixedly connected with the outer wall of the barrel.
No dead angle manhole door, wherein: the diameter of the reinforcing plate is larger than that of the manhole door plate.
No dead angle manhole door, wherein: the two ends of the pressing beam are in contact with the limiting stopper, so that the pressing beam is prevented from rotating and moving.
No dead angle manhole door, wherein: the swing arm includes short arm and long arm, the short arm with the long arm is articulated fixed.
The utility model has the beneficial effects that: the method is safer, more reliable and free of hidden danger, the investment of subsequent expenses such as maintenance or replacement of sealing rings is avoided, the technology is more perfect and mature, and standardized production can be realized.

Detailed Description
As shown in figures 1 to 3, the dead-corner-free manhole door is characterized in that: reinforcing plate 1 is the annular, reinforcing plate 1 and the inner wall welding of barrel 11 become an organic whole, the symmetry sets up a pair of stopper 10 on the outer wall of reinforcing plate 1.
The utility model discloses a manhole door plate, including center pin 5, manhole door plant 2, pressure roof beam 4 and handle 7, overlap in proper order on the center pin 5 and establish pressure roof beam 4 and handle 7, handle 7 with center pin 5 passes through thread engagement, handle 7 supplies through the swivelling movement manhole door plant 2 with pressure roof beam 4 compresses tightly each other, supplies sealedly, pressure roof beam 4's both ends with stopper 10 contact prevents pressure roof beam 4 swivelling movement.
The swing arm 3 includes short arm and long arm, the short arm with the long arm is articulated fixed, the swing arm 3 the long arm with the front end of center pin 5 is articulated fixed, the short arm with support 6 is articulated fixed, support 6 with the outer wall fixed connection of barrel 11.
In the embodiment, the reinforcing plate 1 and the inner wall of the cylinder 1 are welded into a whole, the central shaft 5 is fixedly connected with the manhole door panel 2, the central shaft 5 is hinged with the long arm, the long arm is hinged with the short arm, the short arm is hinged with the support 6, the support 6 is fixed on the outer wall surface of the cylinder 1, the swing arm 3 is moved to drive the central shaft 5 and the manhole door panel 2 to horizontally move together, the manhole door panel 2 is moved to the reinforcing plate 1, the sealing ring 8 is contacted with the reinforcing plate 1, at this time, the pressure beam 4 and the handle 7 are sleeved on the central shaft 5 in sequence, two ends of the pressure beam 4 are contacted with the stopper 11 and prevent the pressure beam 4 from rotating, the handle 7 is engaged with the central shaft 5 by threads, the handle 7 is rotated, and simultaneously drives the pressure beam 4 to move and extrude towards the direction of the manhole door panel 2, the center pin 5 drives manhole door plant 2 to the direction of handle 7 removes, manhole door plant 2's outer wall with press roof beam 4 to compress tightly each other, the inner wall of reinforcing plate 1 with manhole door plant 2's outer fringe compresses tightly each other, sealing washer 8 reaches annular arch 9 with reinforcing plate 1 closely compresses tightly more to play sealed effect.
