[0017] like Figures 1-4 As shown, the present invention proposes an easily adjustable double-ended stainless steel bolt fastening assembly, including a double-ended stainless steel bolt cylinder 1, with double-ended stainless steel bolts 2 installed at both ends of the double-ended stainless steel bolt cylinder 1. Each double-ended stainless steel bolt 2 has an external thread 101 on one side of one end, a shrinkage anti-loosening component 3 on the outside of the external thread 101, and a fastening component 4 sleeved on the outside of the double-ended stainless steel bolt 2.

[0018] In practical use, when tightening the double-ended stainless steel bolt 2 to prevent slippage, the external thread 101 is used to thread-fix the shrinkage anti-slip component 3 to prevent slippage during use. The tightening component 4 is used to tighten and fix the shrinkage anti-slip component 3, and the anti-slip cover 405 is used to thread-fix the double-ended stainless steel bolt 2.

[0019] The shrinkage and anti-detachment component 3 includes a first anti-detachment threaded sleeve 301 connected to the outer thread of the external thread (101), an external thread shrinkage sleeve 303 fixed to the outer thread of the double-ended stainless steel bolt 2, a collar 304 fixedly installed on one side of the external thread shrinkage sleeve 303, a number of small bolt rods 305 connected to the outer thread of the collar 304, and a fastening ring 302 fixedly connected to one end of the small bolt rods 305.

[0020] In practical use, when tightening the threads of the double-ended stainless steel bolt 2 to prevent slippage and detachment, the external threaded shrink sleeve 303 is used for further thread tightening to prevent the first anti-loosening threaded sleeve 301 from slipping off during bolt use. The small bolt rod 305 on the collar 304 is used to tighten the threads of the fastening ring 302, so that the fastening assembly 4 can be clamped and fixed to the double-ended stainless steel bolt 2, preventing the first anti-loosening threaded sleeve 301 and the external threaded shrink sleeve 303 from falling off the double-ended stainless steel bolt 2.

[0021] The fastening assembly 4 includes a rubber clamping sleeve 401 that engages with the inner side of the fastening ring 302. The outer side of the fastening ring 302 has several threaded insertion holes 402. Each threaded insertion hole 402 has a threaded fastening rod 403 threadedly inserted into its interior. A convex part 404 is fixedly connected to one side of the fastening ring 302. An anti-disengagement cover 405 is fitted onto the outer side of the convex part 404.

[0022] In practical use, to prevent the first anti-loosening threaded sleeve 301 and the external threaded shrink sleeve 303 from falling off, the threaded fastening rod 403 is inserted through several threaded insertion holes 402, so that the threaded fastening rod 403 squeezes and clamps the rubber clamping sleeve 401, thereby clamping the double-ended stainless steel bolt 2 and the fastening ring 302 to prevent the first anti-loosening threaded sleeve 301 and the external threaded shrink sleeve 303 from falling off. The anti-loosening cover 405, which is fastened to the outside of the convex part 404, is used to cover and prevent it from falling off and being bumped.

[0023] The rubber clamping sleeve 401 is made of diene and styrene.

[0024] Both the first anti-loosening threaded sleeve 301 and the external thread shrink sleeve 303 are threadedly connected to the external thread 101.

[0025] Working principle: The two ends of the double-ended stainless steel bolt 2 are screwed into the double-ended stainless steel bolt sleeve 1. Its external thread 101 engages with the first anti-loosening threaded sleeve 301 of the shrinkage anti-loosening component 3, forming the first thread lock. The external thread shrinkage sleeve 303 is axially connected to the first anti-loosening threaded sleeve 301 through the collar 304, further strengthening the anti-loosening ability of the thread pair and suppressing the thread backing caused by vibration. By tightening the multiple small bolt rods 305 on the outside of the collar 304, the fastening ring 302 is driven to shrink radially inward. The axial feed of the small bolt rods 305 is converted into the radial shrinkage force of the fastening ring 302, so that the fastening ring 302 tightly clamps the surface of the double-ended stainless steel bolt 2, forming a mechanical interference fit, blocking the loosening path of the thread pair. The rubber clamping sleeve 401 of the fastening component 4 is embedded inside the fastening ring 302. When the thread fastening rod 403 When screwed into the threaded insertion hole 402, the threaded fastening rod 403 squeezes the rubber clamping sleeve 401, causing it to elastically deform and tightly wrap around the bolt surface. The high coefficient of friction of the rubber suppresses the fretting of the bolt. The elastic compensation of the rubber and the rigid contraction of the fastening ring 302 form a compound locking, which adapts to deformation fluctuations under vibration conditions. The anti-dislodgement cover 405 is fastened to the outside of the convex part 404, forming a physical barrier to prevent external impacts from causing the small bolt rod 305 or the threaded fastening rod 403 to loosen accidentally, while also preventing foreign objects from intruding and interfering with the locking structure.
