Description
Technical Field
[0001] This utility model belongs to the technical field of marine connecting accessories, and in particular relates to the structure of marine corrosion-resistant quick-install snap-on connecting accessories. Background Technology
[0002] In the ship's operating environment, multiple devices are often installed around the hull to detect the route status and other tasks. However, the devices are exposed to complex conditions such as high salt spray, high humidity and seawater corrosion for a long time, which can easily lead to damage. Therefore, staff need to carry out regular maintenance and repair.
[0003] Traditional equipment often uses flanges and bolts for connection. However, high salinity and humidity can easily cause flanges and bolts to rust, making it difficult to disassemble and assemble the equipment. In addition, during disassembly and assembly, workers need to remove and install bolts one by one, which is cumbersome, time-consuming and labor-intensive, thus reducing the overall maintenance efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a corrosion-resistant quick-install snap-fit connection accessory structure for marine applications. By setting up a disassembly and assembly mechanism, specifically, the mounting block is aligned with the right end of the mounting column, and the locking ring is rotated clockwise to move it to the right. The right-side annular inclined surface pushes the three locking hooks to rotate the hinge seat, causing the right end to move closer and the left end to move away. After the locking ring moves to its extreme right position, the three locking hooks are in close contact with the outer ring of the mounting block. Then, the pin is fully inserted into the anti-rotation groove of the locking ring. At this point, the mounting block is installed. To remove it, the pin is pulled out, and the locking ring is rotated counterclockwise, causing the three locking hooks to move away on the right and closer on the left under the push of the spring. This design enables quick and efficient disassembly and assembly of equipment, improving maintenance efficiency. It solves the problem that existing marine equipment connection accessories mostly consist of flanges and bolts, which are prone to corrosion in high-salt and high-humidity environments, making disassembly and assembly difficult, time-consuming, and labor-intensive.

[0013] The inner wall of the circular groove is fitted with a support column for sliding limit, and a limit block is fixedly connected to the top of the support column. The outer side of the limit block is adapted to the inner wall of the limit groove, and the limit block and the limit groove are slidably limited together.
[0014] Furthermore, an annular inclined surface is provided on the right side of the outer surface of the locking ring, and an annular arc surface is provided on the right side of the mounting block;
[0015] The right end of the locking hook is adapted to the annular arc surface on the right side of the mounting block, and the three locking hooks are provided with an arc surface adapted to the outer surface of the mounting block on the side that is close to each other.
[0016] Furthermore, the outer surface of the mounting column is provided with three mounting grooves, and a spring is fixedly connected to the bottom of each of the three mounting grooves;
[0017] The three springs are respectively fixedly connected at opposite ends to the three locking hooks at opposite ends. The three mounting slots are all flared, which can effectively prevent friction between the springs and the mounting slots.
[0018] Furthermore, an elastic rope is fixedly connected to the top of the mounting base, and a pin is fixedly connected to the other end of the elastic rope. An anti-rotation groove is provided on the top of the locking ring.
[0019] The anti-rotation groove passes through the locking ring and extends into the interior of the mounting column. The elastic rope is elastically designed. Three rubber sheets are fixedly connected to the outer surface of the pin. The pin is inserted into the anti-rotation groove.
[0020] Furthermore, a second spring is fixedly connected to the left side of the inner wall of the circular groove, and one end of the second spring near the support column is fixedly connected to the left side of the support column.

Then, the pin is fully inserted into the anti-rotation groove of the locking ring. At this time, the mounting block is installed. When removing it, pull out the pin and rotate the locking ring counterclockwise, so that the three locking hooks are pushed by the spring, and the right end moves away and the left end moves closer. This setting can quickly and efficiently disassemble and assemble equipment, improving maintenance efficiency.
[0024] 2. This utility model features a fixing mechanism. Specifically, rotating the wheel clockwise moves the extrusion column toward the center of the mounting column. The hemispherical extrusion groove slope causes the support column to move to the right, and the second spring is stretched. The support column pushes the mounting block and equipment to the right until the annular arc surface is completely in contact with the inner side of the right end of the locking hook. The support column can no longer move. When removing the device, rotating the wheel counterclockwise moves the extrusion column away from the center of the mounting column. The support column loses its extrusion, and the second spring moves it to the left to reset. This design makes the overall fixation more secure and effectively prevents the hull from swaying and causing the fixation to become unstable.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figures 1-5As shown, this utility model is a marine corrosion-resistant quick-release snap-fit connection accessory structure, including a mounting base 1, a mounting plate 11 on the right side of the mounting base 1, and a mounting block 25 fixedly connected to the left side of the mounting plate 11. It also includes a disassembly and assembly mechanism 2, located on the right side of the mounting base 1, used for disassembling and assembling the mounting block 25. The disassembly and assembly mechanism 2 includes a mounting post 21, with three hinge seats 23 fixedly connected to the outer surface of the mounting post 21, each hinge seat 23 having a locking hook 231 hinged inside. It also includes a fixing mechanism 3, located inside the mounting post 21, used to make the fixing of the mounting block 25 by the disassembly and assembly mechanism 2 more stable. The right end of the locking hook 231 is hook-shaped, and the left end is inclined. The three hinge seats 23 and the locking hook 231 are evenly spaced and arranged in a ring on the outer surface of the mounting post 21. The left end of the mounting post 21 is fixedly connected to the right side of the mounting base 1. A threaded groove 211 is provided on the left side of the outer surface of the mounting post 21. A locking ring 22 is provided on the outer surface of the mounting post 21, and the inner ring of the locking ring 22 is threaded. The locking ring 22 is threaded to the threaded groove 211 on the outer surface of the mounting post 21 through the inner ring thread. A circular groove 31 is provided on the right end of the mounting post 21. A limiting groove 311 is provided at the top of the circular groove 31. A threaded groove 312 is provided on the right side of the outer surface of the mounting post 21. A support post 32 is slidably limited to the inner wall of the circular groove 31. A limiting block 321 is fixedly connected to the top of the support post 32. The outer side of the limiting block 321 is adapted to the inner wall of the limiting groove 311, and the limiting block 321 and the limiting groove 311 are slidably limited to each other. An annular inclined surface 221 is provided on the right side of the outer surface of the locking ring 22, and an annular arc surface 251 is provided on the right side of the mounting block 25. The right end of the locking hook 231 is adapted to the annular arc surface 251 on the right side of the mounting block 25, and the sides of the three locking hooks 231 that are close to each other are all provided with arc surfaces adapted to the outer surface of the mounting block 25. Three mounting grooves 24 are opened on the outer surface of the mounting post 21, and springs 241 are fixedly connected to the bottom of the three mounting grooves 24. The ends of the three springs 241 that are far apart from each other are fixedly connected to the sides of the three locking hooks 231 that are close to each other. The three mounting grooves 24 are all flared.An elastic rope 261 is fixedly connected to the top of the mounting base 1, and a pin 26 is fixedly connected to the other end of the elastic rope 261. An anti-rotation groove 222 is provided on the top of the locking ring 22. Align the mounting block 25 with the right end of the mounting post 21, and rotate the locking ring 22 clockwise to move it to the right. This pushes the three locking hooks 231 through the right-side annular inclined surface 221, causing the hinge seat 23 to rotate. The right end of the hooks moves closer to the mounting block 25, and the left end moves further away. After the locking ring 22 moves to its extreme right position, the three locking hooks 231 are in close contact with the outer ring of the mounting block 25. Then, the pin 26 is fully engaged. When the anti-rotation groove 222 of the locking ring 22 is fully inserted, the mounting block 25 is installed. To remove it, pull out the pin 26 and turn the locking ring 22 counterclockwise. This causes the three locking hooks 231 to move away from each other on the right and closer on the left under the push of the spring 241. This setting enables quick and efficient disassembly and assembly of the equipment, improving maintenance efficiency. The anti-rotation groove 222 passes through the locking ring 22 and extends into the interior of the mounting post 21. The elastic rope 261 is elastic. Three rubber pieces are fixedly connected to the outer surface of the pin 26. The pin 26 is inserted into the anti-rotation groove 222. A spring 33 is fixedly connected to the left side of the inner wall of the circular groove 31. The end of the spring 33 near the support column 32 is fixedly connected to the left side of the support column 32. A pressing column 34 is provided inside the threaded groove 312. The outer surface of the pressing column 34 is threaded, and the pressing column 34 is threaded to the threaded groove 312. When the rotating wheel 341 is rotated clockwise, the pressing column 34 moves towards the center of the mounting column 21. Its hemispherical surface presses the inclined surface of the pressing groove 322, causing the support column 32 to move to the right. The spring 33 is stretched, and the support column 32 pushes the mounting block 25 and the equipment to the right until the annular arc surface 251 is completely engaged with the locking hook 2. When the right end of the hook-shaped inner side contacts the support column 32, the support column 32 cannot move further. When removing it, rotate the wheel 341 counterclockwise, and the pressing column 34 moves away from the center of the mounting column 21. The support column 32 loses its compression, and the spring 33 moves it to the left to reset. This setting can make the overall fixation more secure and can effectively prevent the hull from swaying and causing the fixation to be unreliable. Among them, the end of the pressing column 34 away from the mounting column 21 is fixedly connected to the wheel 341, the outer surface of the support column 32 is provided with a pressing groove 322, the inner wall of the pressing groove 322 is provided with a slope, and the end of the pressing column 34 away from the wheel 341 is hemispherical.
[0036] A specific application of this embodiment is as follows: In use, first use bolts to install the mounting base 1 in the reserved position, then fix the mounting plate 11 to the equipment, and then align the mounting block 25 on the left side of the equipment and mounting plate 11 with the right end of the mounting post 21. After alignment, rotate the locking ring 22 clockwise. Since the locking ring 22 is threadedly connected to the thread groove 211 of the mounting post 21 through the inner ring thread, the locking ring 22 will move to the right. During the rightward movement, it will push the three locking hooks 231 through the right annular inclined surface 221 to respectively hinge. The seat 23 rotates around the axis. At this time, the right ends of the three locking hooks 231 approach each other and the left ends move away from each other. After the locking ring 22 moves to the right limit position, the side of the three locking hooks 231 that approach each other is in close contact with the outer ring of the mounting block 25. Then, the pin 26 is fully inserted into the anti-rotation groove 222 on the locking ring 22. During the insertion process, the anti-rotation groove 222 will squeeze the three rubber pieces on the outer surface of the pin 26. At the same time, the rubber pieces can make the pin 26 firmly inserted into the anti-rotation groove 222 and will not easily fall off. At this time, the mounting block 25 has been installed.
[0037] Then, rotating the wheel 341 clockwise, the extrusion column 34 will move towards the center of the mounting column 21 because it is threadedly connected to the threaded groove 312. During the movement, the hemispherical surface at one end of the extrusion column 34 will press against the inclined surface of the inner wall of the extrusion groove 322, causing the support column 32 to move to the right. At this time, the spring 33 is stretched, and the rightward movement of the support column 32 will push the mounting block 25 and the equipment to move to the right together until the annular arc surface 251 is completely in contact with the inner side of the right hook-shaped setting of the locking hook 231. At this point, the support column 32 can no longer move. In actual use, at least two mounting plates 11 will be installed on the equipment to ensure that the equipment is installed securely. Similarly, two mounting bases 1 and two mounting columns 21 will be installed, so the other one will be installed in the same way. When the equipment and mounting block 25 need to be removed, first rotate the wheel 341 counterclockwise to move the extrusion column 34 away from the center of the mounting column 21. After the support column 32 loses its extrusion, the second spring 33 uses its own elasticity to move the support column 32 to the left and reset it. Then, after forcefully pulling out the pin 26, rotate the locking ring 22 counterclockwise. After the left ends of the three locking hooks 231 lose their push, the first spring 241 pushes the right ends of the three locking hooks 231 away from each other and the left ends closer to each other. After the locking ring 22 moves to the left limit position, the left ends of the locking hooks 231 continue to contact the annular inclined surface 221. The material of the above structure is 316 stainless steel, which can effectively resist seawater corrosion and improve the service life of the entire structure.
