Problems solved by technology

[0006] However, due to the limitation of the width of the cabin passage, when the cabin door is opened, the crew cannot enter the safe cabin from both sides of the passage at the same time. The locking mechanism inside the cabin is not strong, and the general cabin door can be opened from the outside. Breaking and entering, threatening the lives of the crew

Embodiment 1

[0025] A single-column double-point inner-opening hidden safety door link mechanism is characterized in that the link mechanism is divided into left and right link mechanisms, and the left and right link mechanisms have the same structure. The left and right link mechanisms at least include a first link 8 and a second link 7, one end of the first link 8 is connected to the large gear plate shaft, and the other end of the first link 8 is connected to the second link 7 through the connecting plate. connection, the second connecting rod 7 is parallel to the left and right sides of the door frame 1, and the second connecting rod 7 is distributed with a plurality of door buckle mechanisms from top to bottom; the door frame 1 is connected with the door panel 3 through the door ear 9 and the door shaft 10; the door panel 3 is connected with operating handwheel 11 on the central axis.

Embodiment 2

[0027] A single-column double-point inward-opening invisible safety door adopting the linkage mechanism at least includes a door frame 1 and a door panel 3, and the door frame 1 is connected to the door panel 3 through the door lug 9 and the door shaft 10, and is characterized in that: the central axis of the door panel 3 An operating handwheel 11 is connected to the top, and there is a pinion 20 on the shaft of the operating handwheel 11. The pinion 20 is coupled with the teeth of the large gear 12 at the lower end of the central axis. The left and right gear plates of the large gear 12 are respectively connected with a set of linkage mechanisms and door buckles. Mechanism is connected door buckle mechanism by left and right link mechanisms, and the left and right frames of door frame 1 are compressed or clutched by the compression wedge of door buckle mechanism.

[0028] The left and right link mechanisms have the same structure.

Abstract

The invention relates to a single-column double-point inward-opening invisible safety gate link mechanism, characterized by being divided into a left link mechanism and a right link mechanism which are the same in structure. Each of the left link mechanism and the right link mechanism at least comprises a first connecting rod and a second connecting rod; certain ends of the first connecting rods are connected with a big gear plate shaft; the other ends of the first connecting rods are connected with the second connecting rods by connecting plates; the second connecting rods are parallel to left and right edges of a door frame, and are provided with multiple door holder mechanisms from top to bottom; the door frame is connected with a door panel by door lugs and a door shaft; the central axis of the door panel is connected with an operation hand wheel. The single-column double-point inward-opening invisible safety gate link mechanism has the characteristics of high safety, good convenience in use, reasonable process, and the like.

Description

technical field [0001] The invention relates to a safety door link mechanism, in particular to a single-column double-point inner-opening hidden safety door link mechanism. Background technique [0002] In recent years, there have been piracy activities in many international navigation areas around the world, and they have become more and more rampant. Pirates have frequently hijacked ships, posing a great danger to the interests of shipowners and the lives of crew members. The living area of ​​the ship is generally located at the rear of the ship, the wheelhouse is located at the top of the living area, and the engine room is located at the lower part of the living area. There is a door on the main deck leading directly to the living area. At the same time, there are stairs outside the main deck leading directly to the observation platform outside the bridge. There is also a door designed between the observation platform and the pilothouse. In addition, there are often do...
