[0026] The first column 1 and the second column 2 form a ship door column made of glass fiber reinforced plastic. The railing door 4 is rotated on one side of the first column 1 through a rotating shaft 9, and the second column 2 is plugged with the railing door 4 through a connecting block 10 on one side through a front limit block 14 and a latch 15, so that the railing door 4 can be opened or closed for use;

[0027] The top end of the rotating shaft 9 is a convex structure. The rotating shaft 9 is inserted into the two hinges 8, and the bottom end extends to the bottom of the angle steel 7 and is limited by the nut sleeve, so that the rotating shaft 9 can be installed quickly and conveniently, and the convenient disassembly and assembly of the railing door 4 is realized. At the same time, one end of the two angle steels 7 is fitted with the outer periphery of the two lower stop rods 6 of the railing door 4 through the positioning block 16, which plays a limiting support role between the back of the railing door 4 and the first column 1. The limiting rod 12 and the O-ring 13 play a limiting and fixing role between the top of the railing door 4 and the first column 1. At the same time, the limiting rod 12, the O-ring 13 and the eye plate 11 are easy to disassemble and assemble, realizing the convenience of disassembly and assembly of the limiting mechanism in the railing door 4 of the ship;

[0028] When the railing door 4 is fitted with the second column 2 through the connecting block 10, the protruding stop block 19 is squeezed, and the spherical block at the end of the stop block 19 is squeezed and then the tension spring 17 is squeezed, so that the pin 15 is retracted to the other side along the insertion hole. When the connecting block 10 is aligned with the insertion hole on one side of the limit block 14, the tension spring 17 is quickly reset, so that the stop block 19 is plugged into the insertion hole opened on one side of the limit block 14, thereby realizing the convenient plug-in of the connecting block 10 on one side of the railing door 4 and the pin 15 in the limit block 14 on the second column 2, avoiding the traditional manual plug-in and unplugging, which is inconvenient to use.

[0030] Among them, hinges 8 are fixedly installed on the adjacent sides of the first column 1 and the railing door 4, and a stop block 18 is provided on the outer periphery of the stop block 19 near the latch 15. The stop block 18 plays a limiting role, so that after the stop block 19 is reset by the elastic force of the tension spring 17, the stop block 19 can be accurately plugged into the socket in the connecting block 10 and positioned.

[0031] Among them, the distance between the railing door 4 and the first column 1 and the second column 2 is a clearance fit, the top end of the rotating shaft 9 movably passes through the top of the two hinges 8, and the top end of the rotating shaft 9 is a convex structure. The top end of the rotating shaft 9 is a convex structure.

[0032] Among them, the number of lower baffles 6 and angle steels 7 corresponds one to one, the positioning block 16 is an arc structure, and the lower baffle 6 and the inner wall of the positioning block 16 are clearance-matched. The positioning block 16 at the other end of the two angle steels 7 can accurately support the two lower baffles 6 on the railing door 4, thereby preventing the railing door 4 from rotating to a certain angle, and providing a limiting support between the back of the railing door 4 and the first column 1, thereby preventing the ship from being shaken after the railing door 4 is opened, and preventing the railing door 4 from repeatedly rotating and being unable to be positioned.

[0033] Among them, the limiting rod 12 is an L-shaped structure, and the other end of the limiting rod 12 is inserted into the inner wall of the eye plate 11 on the periphery of the upper blocking rod 5. The O-ring 13 is a tough steel structure, and the O-ring 13 is an O-shaped structure. The O-ring 13 is sleeved in the inner wall of the eye plate 11 at the top of the front face of the first column 1. The limiting rod 12 and the O-ring 13 play a limiting and fixing role between the top of the railing door 4 and the first column 1. At the same time, the limiting rod 12, the O-ring 13 and the eye plate 11 are easy to disassemble and assemble, thereby realizing the convenience of disassembly and assembly of the limiting mechanism in the railing door 4 of the ship.

[0034] Among them, the connecting block 10 is an L-shaped structure, the limit block 14 is a concave structure, and holes are opened on one side of the connecting block 10 and the limit block 14. The tension spring 17 is a conical structure, and the other end of the tension spring 17 is fixedly connected to one side of the inner wall of the limit block 14. The stopper 18 is located in the inner wall of the limit block 14, and the other end of the stop block 19 passes through the hole opened on the inner wall of the limit block 14 and extends to the outer side of the limit block 14. After the connecting block 10 is aligned with the hole on one side of the limit block 14, the tension spring 17 is quickly reset, so that the stop block 19 is plugged into the hole opened on one side of the limit block 14, realizing the convenient plug-in of the connecting block 10 on one side of the railing door 4 and the pin 15 in the limit block 14 on the second column 2.

[0035] Working principle: When in use, the first column 1 and the second column 2 form a ship door column made of fiberglass, the railing door 4 rotates on one side of the first column 1 through the rotating shaft 9, and the second column 2 is connected to the railing door 4 through the front limit block 14 and the latch 15 through the connecting block 10 on one side, so that the railing door 4 can be opened or closed for use. When it is necessary to open the railing door 4, the stopper 18 can be toggled to compress the tension spring 17, and the latch 15 drives the stopper 19 to shrink into the socket in the limit block 14. The railing door 4 can be opened from between the first column 1 and the second column 2. When the railing door 4 is opened to a certain angle, one end of the two angle steels 7 fits with the outer periphery of the two lower stop rods 6 of the railing door 4 through the positioning block 16, which plays a limiting support role between the back of the railing door 4 and the first column 1. The limiting rod 12 and the O-ring 13 play a limiting and fixing role between the top of the railing door 4 and the first column 1. At the same time, the limiting rod 12, the O-ring 13 and the eye plate 11 are easy to disassemble and assemble, thereby realizing the convenient disassembly and assembly of the limiting mechanism in the ship's railing door 4.
