Abstract

The present invention relates to a lifting translational vertically-rotated hinge device. Its upper shaft and translational jack are up-down perpendicularly opposite, the upper shaft and upper seat exterior of aid translational jack are covered with a conantric steel pipe, and the upper shaft is passed through an upper connecting plate. The translational jack has an outer cylinder, its upper end has an upper seat, under the upper seat a large bevel gear is set, said large bevel gear is meshed with a side small bevel gear, said large bevel gear is connected with a lifting screw rod by means of-connecting key, the lower end of said lifting screw rod is connected with the translational telescopic shaft by means of screw, the lower end of core portion of said translational telescopic shaft iscovered with a hammerhead-shaped translational head, on the under surface of said translational head an upper ball groove is cut. The lower hinge seat is connected with a groove-shaped lower translational block seat by means of bearing, in the interior of lower translational block seat a lower translational block is set, on the upper surface of said lower translational block a lower ball groove is cut, between said lower ball groove and upper ball groove a row of steel balls is set.

Description

technical field [0001] The invention relates to a protective device for civil air defense projects and national defense projects, in particular to a protective airtight door for large-scale civil air defense underground garages, entrances and exits of underground shopping malls and communication ports. Background technique [0002] The entrances and exits and connecting ports of large-scale civil air defense underground garages and underground shopping malls (as air defense basements during wartime) need to be installed with protective airtight doors. The hinges used in the existing vertical-rotating, landing-translation-vertical-rotating double-leaf steel structure protective airtight doors have the following disadvantages: [0003] (1) The upper, middle, and lower parts of the hinge device are independent of each other, and it is not easy to ensure the coaxiality and verticality of the three parts during on-site construction. [0004] (2) Especially when the door leaf is l...
