[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 In this embodiment, a quickly adjustable anti-piracy fence retractable and folding mechanism includes a fixing seat 1, and a fixing adjustment mechanism is provided inside the fixing seat 1.

[0023] In this embodiment, the fixing adjustment mechanism includes a fixing column 2 movably connected to the top of the fixing base 1, and the internal thread of the fixing base 1 is connected to a fixing bolt 3 threadedly connected to the fixing column 2. The front and rear sides of the fixing base 1 and the fixing column 2 are provided with corresponding thread grooves, and the fixing bolt 3 is threadedly connected to the fixing base 1 and the fixing column 2 through the thread groove, which helps to use the fixing bolt 3 to quickly disassemble and assemble the fixing base 1 and the fixing column 2.

[0024] Among them, the interior of the fixed seat 1 is hinged with a pillar 4, the outer side of the fixed column 2 is movably connected to the movable seat 201, and a movable groove is provided inside the movable seat 201. The movable seat 201 is movably connected to the fixed column 2 through the movable groove, which helps the movable seat 201 to slide and move on the outer side of the fixed column 2. The front and rear inner walls of the movable seat 201 are fixedly installed with an installation box 5, and the front and rear sides of the movable seat 201 are provided with an installation groove. The installation box 5 is fixedly connected to the movable seat 201 through the installation groove, which helps to install and fix the installation box 5.

[0025] In this embodiment, a return spring 6 is fixedly installed inside the installation box 5, and a movable plate 7 is fixedly installed on one side of the return spring 6. The top and bottom of the movable plate 7 are fixedly installed with limit blocks 8 movably connected to the installation box 5. A limit groove is provided inside the installation box 5, and the limit block 8 is slidably connected to the installation box 5 through the limit groove, which helps to limit the limit block 8. An adjusting rod 9 extending to the outside of the installation box 5 is fixedly installed on one side of the movable plate 7, and a pull ring 10 is fixedly installed on one side of the adjusting rod 9.

[0026] Among them, a limit pin 11 that is plugged into the fixed column 2 is fixedly installed on the side of the movable plate 7 away from the adjusting rod 9. A number of evenly distributed slots are opened on both sides of the fixed column 2. The limit pin 11 is plugged into the fixed column 2 through the slots, which makes it convenient to use the limit pin 11 to plug, fix and disassemble the fixed column 2. A fixed frame 12 is fixedly installed on one side of the movable seat 201. A movable rod 13 is hinged inside the fixed frame 12. The movable rod 13 is hinged on the side away from the fixed frame 12 to a hinged seat 14 that is fixedly connected to the pillar 4.

[0027] It should be noted that the quickly adjustable anti-pirate fence retractable and folding mechanism uses a fixed adjustment mechanism to rotate and retract the movable rod 13 on the inner side of the hinged seat 14, and the pull ring 10, the adjustment rod 9 and the movable plate 7 can compress the reset spring 6, and the movable plate 7 drives the limit pin 11 to move and retract until the limit pin 11 is separated from the inside of the fixed column 2, so that the movable seat 201 can slide up and down on the outside of the fixed column 2, which is convenient for more effective retraction and retraction.

[0028] The working principle of the above embodiment is:

[0029] The quickly adjustable retractable and foldable anti-piracy fence mechanism can be used to directly pull the pillar 4 to move when it is needed to retract the pillar 4 during use. The pillar 4 rotates inside the fixed seat 1, and the movable rod 13 rotates and shrinks inside the hinge seat 14. In addition, the pull ring 10 can be pulled during use, and the pull ring 10 drives the adjusting rod 9 to move. The movement of the adjusting rod 9 drives the movable plate 7 to move inside the installation box 5. The movable plate 7 moves smoothly under the limit of the limit block 8. The movement of the movable plate 7 compresses the return spring 6, and the movable plate 7 drives the limit pin 11 to move and shrink until the limit pin 11 is separated from the inside of the fixed column 2, so that the limit pin 11 no longer limits the insertion of the fixed column 2.

[0030] Then the movable seat 201 can be directly pulled to slide up and down on the outside of the fixed column 2. The movable seat 201 moves and drives the fixed frame 12 to move up and down. When the fixed frame 12 moves up and down, the movable rod 13 can be driven to rotate and retract on the inside of the fixed frame 12, thereby driving the hinged seat 14 to further retract and move, which is convenient and effective for retraction and retraction, and can increase the interception height when the pillar 4 is used as a fence, and can facilitate and quickly adjust the interception height of the fence. At the same time, the fixed column 2 can be disassembled and installed using the fixing bolt 3. This application is used in the field of ship chemical operations to install anti-piracy fences on ships. The fence uses this utility model technology. When it is stretched and opened, the bottom of the fence can prevent pirates from climbing up from the bottom of the ship. When it is not needed, it can be directly retracted and folded, and fixed by snapping. It is extremely flexible.
