Problems solved by technology
When the mechanism closes the door, the left and right sides are limited and locked to ensure that the door frame and door leaf are pressed tightly, but there is no locking mechanism for the direction of opening and closing the door.
Since the fire-proof watertight door is required to be in a locked state in a fire environment, this type of watertight door cannot be realized.
The old structure does not have a locking mechanism for opening and closing the door, so it cannot realize the function of locking the door safely in case of fire

Embodiment Construction
[0015] The specific embodiments of the present invention will be further described below in conjunction with the drawings.
[0016] Figure 1~5 It includes door leaf 1, door frame 2, guide post card board 3, card block 3-1, connecting body 3-2, spring one 3-3, welding seat 3-4, operating device 4, operating handle 4-1, Cylindrical pin 4-2, movable ear plate 4-3, eccentric wheel 4-4, spring two 4-5, shaft 4-6, mounting seat 4-7, guide slider 5, locking pin 6, guide rail 7, Drive cylinder assembly 8, rubber ramp pad 9, outer sealing plate 10, drive device 11, handle 12, etc.
[0017] Such as Figure 1~5 As shown, the present invention is an automatic locking mechanism and a fire-proof watertight door, comprising a door frame 2 and a door leaf 1 slidably arranged on the door frame 2. A number of locking pins 6 are evenly arranged on the side of the door leaf 1 along the vertical direction. , The door frame 2 is provided with a round hole that matches the locking pin 6; the door fra...

The invention belongs to the technical field of ships and relates to an automatic locking mechanism and a fireproof watertight door. The fireproof watertight door comprises a door frame and a door leaf slidably arranged on the door frame and is characterized in that a plurality of locking pins are uniformly arranged on the side face of the door leaf in the vertical direction; circular holes matched with the locking pins are formed in the door frame; a guiding sliding block is mounted on the door frame in the vertical direction; a guiding column clamping plate which can slide up and down is arranged in the guiding sliding block; the bottom of the guiding column clamping plate is connected with a welded seat fixed on the door frame through a first spring; and the guide column camping plate slides up and down through an operation device arranged on the door frame to lock or loosen grooves in a locking pin shaft. When the fireproof watertight door is closed, the locking mechanism can be inserted automatically, and manual locking is not needed; when the fireproof watertight door is opened, a handle drives an eccentric wheel to rotate to automatically unlock the locking mechanism; and when manual operation does not occur, the mechanism automatically returns to the neutral position, and safety and reliability are achieved.
Description
Technical field [0001] The invention belongs to the technical field of ships, and relates to an automatic locking mechanism and a fireproof watertight door. Background technique [0002] Such as figure 2 As shown, the old watertight door consists of a driving device 11, a door frame 2, a door leaf 1, and a guide rail 7. When the mechanism closes the door, the left and right sides are limited and locked to ensure that the door frame and the door leaf are pressed tightly, but there is no locking mechanism for opening and closing the door. Since the fireproof watertight door is required to be locked in a fire environment, this type of watertight door cannot be realized. The old structure does not have a locking mechanism for opening and closing the door, so it cannot achieve the function of safely locking the door in the event of a fire. Summary of the invention [0003] In view of the above-mentioned problems, the present invention provides an automatic locking mechanism and a fir...
