[0001] This utility model relates to the field of nut connector technology, and in particular to a marine stainless steel nut that is easy to assemble and disassemble. Background Technology
[0002] In the field of shipbuilding and maintenance, stainless steel nuts are used as key connecting components in the installation and fixing of various parts such as hull structure, power system, and deck equipment.
[0003] However, existing nuts are cumbersome to install and remove, and take a long time. Furthermore, vibrations during ship navigation can easily cause the nuts to loosen. Existing anti-loosening structures (such as spring washers) are prone to diminishing effectiveness, and locking washers are difficult to reuse, resulting in unreliable installation after disassembly and affecting subsequent stable use. Therefore, this utility model proposes a marine stainless steel nut that is easy to install and remove. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a marine stainless steel nut that is easy to assemble and disassemble.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A marine stainless steel nut that is easy to assemble and disassemble includes a hull, marine components, a bolt rod fixedly connected to the hull, and a stainless steel nut body threadedly connected to the bolt rod; the marine components are provided with mounting holes, and the marine components are sleeved on the bolt rod through the mounting holes; a washer is provided at the bottom of the stainless steel nut body, and the stainless steel nut body abuts against the marine components through the washer.
[0007] Both ends of the stainless steel nut body are provided with compression chambers. A pressure block is movably installed in the compression chamber. The outer end of the pressure block movably extends to the outside of the stainless steel nut body. A reset spring is fixedly connected between the inner end of the pressure block and the inner wall of the compression chamber. A cavity is provided on the washer ring located below the compression chamber. A movable block is slidably installed on the inner wall of the bottom side of the cavity. A locking block is fixedly connected to the movable block. The end of the locking block away from the movable block movably extends to the inner side of the washer ring and is fixedly connected to a locking tooth head. Annular locking tooth grooves are evenly provided on the circumference of the bolt rod. The locking tooth head engages with the annular locking tooth grooves for positioning. A reset spring is fixedly connected between the movable block and the outer inner wall of the cavity. A pull rope is fixedly connected to the movable block. The other end of the pull rope movably extends into the compression chamber and is fixedly connected to the bottom side of the pressure block.
[0008] Furthermore, a first fixed pulley is rotatably installed inside the cavity, and a second fixed pulley is rotatably installed inside the compression cavity. The pull rope is connected to the first fixed pulley and the second fixed pulley in sequence.
[0009] Furthermore, a transmission hole is provided between the cavity and the compression cavity, through which the pull rope moves.
[0010] Furthermore, a slider is fixedly provided on the top side of the pressure block, and a guide rail is fixedly provided on the inner wall of the top side of the compression chamber, with the slider slidingly mounted on the guide rail in the horizontal direction.
[0011] Furthermore, the outer inner wall of the compression chamber is provided with a movable hole, through which the pressure block moves; the upper middle part of the bolt rod is provided with an external thread, and the bolt rod is threadedly connected to the stainless steel nut body through the external thread.
[0012] Furthermore, a slide rail is fixedly installed on the bottom inner wall of the cavity, and a slide groove is provided at the bottom of the movable block. The bottom of the movable block is slidably installed on the slide rail in the horizontal direction through the slide groove.
[0013] The beneficial effects achieved by this utility model using the above structure are as follows:
[0014] This invention not only facilitates the disassembly and assembly of the stainless steel nut body on marine components, but also makes it easy to thread the stainless steel nut body and washer together onto the bolt rod. After tightening, the stainless steel nut body will abut against the marine component through the washer, thereby fixing the marine component onto the hull. At the same time, by having the retaining head engage with the annular retaining groove on the bolt rod for positioning, this engagement and positioning of the retaining head and the annular retaining groove can prevent the washer and the stainless steel nut body from loosening after installation, thus ensuring a more secure threaded installation between the stainless steel nut body and the bolt rod, and ensuring the stable installation of the marine components.
[0015] In summary, this easy-to-disassemble marine stainless steel nut is simple to operate, easy to disassemble or install, and ensures a very secure installation after disassembly, avoiding the situation where the nut easily loosens due to vibration during ship navigation, thus affecting subsequent stable use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 A marine stainless steel nut that is easy to assemble and disassemble includes a hull 1, marine components 2, a bolt rod 3 fixedly connected to the hull 1, and a stainless steel nut body 4 threadedly connected to the bolt rod 3; the marine components 2 are provided with mounting holes 201, and the marine components 2 are sleeved on the bolt rod 3 through the mounting holes 201; a washer 5 is provided at the bottom of the stainless steel nut body 4, and the stainless steel nut body 4 abuts against the marine components 2 through the washer 5;
[0023] Both ends of the stainless steel nut body 4 are provided with compression chambers 402. A pressure block 401 is movably installed within each compression chamber 402. The outer end of the pressure block 401 extends movably through to the outside of the stainless steel nut body 4. A reset spring 403 is fixedly connected between the inner end of the pressure block 401 and the inner wall of the compression chamber 402. A cavity 501 is provided on the washer 5 located below the compression chamber 402. A movable block 502 is slidably installed on the bottom inner wall of the cavity 501. A locking block 503 is fixedly connected to the movable block 502. One end of block 503 away from movable block 502 extends movably through to the inner side of washer 5 and is fixedly connected to a toothed head 504. Circular toothed grooves 302 are evenly provided on the circumference of bolt rod 3. The toothed head 504 engages with the circular toothed grooves 302 for positioning. A return spring 505 is fixedly connected between movable block 502 and the outer inner wall of cavity 501. A pull rope 6 is fixedly connected to movable block 502. The other end of pull rope 6 extends movably through to compression cavity 402 and is fixedly connected to the bottom side of pressure block 401.
[0024] In this embodiment, a first fixed pulley 506 is rotatably installed in the cavity 501, and a second fixed pulley 507 is rotatably installed in the compression cavity 402. The pull rope 6 is connected to the first fixed pulley 506 and the second fixed pulley 507 in sequence. A transmission hole 508 is provided between the cavity 501 and the compression cavity 402, and the pull rope 6 moves through the transmission hole 508.
[0025] In this embodiment, a slider 404 is fixedly provided on the top side of the pressure block 401, and a guide rail 405 is fixedly provided on the inner wall of the top side of the compression chamber 402. The slider 404 is slidably mounted on the guide rail 405 in the horizontal direction.
[0026] In this embodiment, the outer inner wall of the compression chamber 402 is provided with a movable hole 406, and the pressure block 401 is movably passed through the movable hole 406; the upper middle part of the bolt rod 3 is provided with an external thread 301, and the bolt rod 3 is threadedly connected to the stainless steel nut body 4 through the external thread 301.
[0027] The cavity 501 has a slide rail 509 fixedly installed on the bottom inner wall, and the bottom of the movable block 502 has a slide groove. The bottom of the movable block 502 is slidably installed on the slide rail 509 in the horizontal direction through the slide groove.
[0028] like Figure 1-4The illustrated marine stainless steel nut facilitates the disassembly and assembly of the stainless steel nut body 4 on marine components. When disassembly is required, an adjustable wrench is used to press two pressure blocks 401 together, thereby clamping the adjustable wrench onto the stainless steel nut body 4. When the two pressure blocks 401 press together, they compress the reset spring 403. At the same time, the pull rope 6 pulls the movable block 502 and compresses the reset spring 505. When the movable block 502 is pulled, it also drives the locking tooth head 504 on the locking block 503 to move, thereby releasing the locking tooth head 504 from the annular locking tooth groove 302 on the bolt rod 3. Then, the stainless steel nut body 4 is loosened by twisting the threads with an adjustable wrench, and the stainless steel nut body 4 and the washer 5 can be removed from the bolt rod 3 together for disassembly of marine components 2. When installation is required, the reverse operation is used. The marine component 2 is fitted onto the bolt rod 3 through the mounting hole 201. Using an adjustable wrench, the two pressure blocks 401 are brought close together and pressed, thus clamping the adjustable wrench onto the stainless steel nut body 4. The stainless steel nut body 4 and bolt rod 3 are then threaded together, allowing the stainless steel nut body 4 and washer 5 to be threaded onto the bolt rod 3. Simultaneously, after tightening, the stainless steel nut body 4 will abut against the marine component 2 through the washer 5, thus fixing the marine component 2 onto the hull 1. Afterwards, the adjustable wrench is released from clamping the two pressure blocks 401, and the return spring 505 and return spring... All pieces 403 are reset, which allows the locking teeth 504 on the locking block 503 to engage and position with the annular locking groove 302 on the bolt rod 3. This engagement and positioning between the locking teeth 504 and the annular locking groove 302 prevents the threads of the washer 5 and the stainless steel nut body 4 from loosening after installation. This ensures a more secure threaded installation between the stainless steel nut body 4 and the bolt rod 3, ensuring the marine component 2 is installed firmly. The operation is simple, easy to disassemble or install, and the installation after disassembly is very secure, avoiding the situation where the nut easily loosens due to vibration during ship navigation, thus affecting subsequent stable use.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
