Embodiment 1

[0033] like Figure 1 to Figure 5 As shown, the marine steel watertight fire door includes a door frame 1 and a door body 2, the door frame 1 is hingedly connected with the door body 2, and the door body 2 is fixedly equipped with a door lock device 3 that can change the way of opening the door. The lock device 3 includes a mounting ring 4, which is rotatably connected with the door body 2, and a double-sided ring gear 5 is fixedly mounted on the mounting ring 4, and a plurality of first gears are engaged with the outside of the double-sided gear ring 5 6. A first installation shaft 7 is fixedly installed on the first gear 6, the bottom end of the first installation shaft 7 is rotatably connected with the door body 2, and the top end of the first installation shaft 7 is fixedly installed with a limit block 8, so The restricting block 8 rotates against the door frame 1, and a power device 9 is engaged with the inside of the double-sided ring gear 5. When the door body 2 is comb...

Embodiment 2

[0037] like Figure 1 to Figure 5 As shown, this embodiment is basically the same as the first embodiment. Preferably, there are four first gears 6 and are symmetrically distributed on both sides of the door body 2 , so that the stress points of the door body 2 are averaged.

[0038] The upper and lower sides of the door body 2 are rotatably connected with fourth installation shafts 25 , and pulleys 26 are fixedly mounted on the two fourth installation shafts 25 and the two first installation shafts 7 , and between the two pulleys 26 A transmission belt 27 is sleeved, and a limit block 8 is fixedly mounted on the fourth installation shaft 25;

[0039] Among them, when the first installation shaft 7 rotates with the first gear 6, it will drive the pulley 26 and the transmission belt 27 to rotate, thereby driving the fourth installation shaft 25 and the restricting block 8 to rotate and work, adding two restricting blocks 8, to the door body 2. A fixed limit is imposed on the o...

Embodiment 3

[0041] like Figure 1 to Figure 5 As shown, this embodiment is basically the same as the first embodiment. Preferably, the restricting block 8 is in the shape of a hook, and the thickness gradually increases from the end to the corner. When the door body 2 is closed, it is not necessary to force the door body 2 Tension, when the restricting block 8 rotates, the interval between it and the door frame 1 is gradually reduced until the door body 2 and the door frame 1 are closely matched to ensure the tightness.

Abstract

The marine steel watertight fireproof door comprises a door frame and a door body, the door frame is hinged to the door body, a door lock device capable of changing door opening modes is fixedly installed on the door body, the door lock device comprises an installation ring, the installation ring is rotationally connected with the door body, a double-side gear ring is fixedly installed on the installation ring, and the double-side gear ring is rotationally connected with the door body. A plurality of first gears are meshed with the outer side of the double-side gear ring, first mounting shafts are fixedly mounted on the first gears, the bottom ends of the first mounting shafts are rotationally connected with the door body, limiting blocks are fixedly mounted at the top ends of the first mounting shafts and rotationally abut against the door frame, and a power device is meshed with the inner side of the double-side gear ring. The invention discloses a marine steel watertight fireproof door which can solve the problems that when an existing watertight fireproof door is maintained at ordinary times, manual opening and closing operation is needed, time and labor are wasted, and the opening and closing efficiency is poor.

Description

technical field [0001] The invention relates to the technical field of marine doors and windows, in particular to marine steel watertight fire doors. Background technique [0002] The watertight fire door is a sealed door used in the hull compartment. When the hull is broken, the watertight fire door can be closed to ensure that the compartment can withstand the flooding of the hull. At the same time, in the event of a fire, it can isolate the flame from entering the compartment and protect the personnel from injury. Rescue, the existing watertight fire doors used in ship hulls need to be manually opened and closed during normal maintenance to check whether the door lock transmission of the watertight fire doors is damaged. Manual inspection is very time-consuming and laborious, and the opening and closing efficiency is poor. SUMMARY OF THE INVENTION [0003] (1) Technical problems solved [0004] Aiming at the deficiencies of the prior art, the invention discloses a mari...
