[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The embodiment of the utility model provides a technical solution: an anti-disassembly type grid nut, comprising a device body 1, the device body 1 comprises a main fixing bolt body 2, a grid nut 3 and an anti-loosening fixture 4, the grid nut 3 is fixed in the main fixing bolt body 2, and the anti-loosening fixture 4 is fixed on the main fixing bolt body 2 and the grid nut 3;

[0021] The problem is that the anti-loosening fixture 4 includes a rotating cover 5, a locking block 6 and a locking threaded bolt 7. The locking block 6 is a cylindrical structure and is installed at the front end of the rotating cover 5. The locking threaded bolt 7 is installed at the front end of the locking block 6. The rotating cover 5 is a circular structure and a plurality of anti-sliding blocks 11 are provided on the surface. The rotating cover 5, the locking block 6 and the locking threaded bolt 7 are a smooth transition and an integral stamping structure. When in use, the staff inserts the main fixing bolt body 2 into the part fixing hole, and then the top of the main fixing bolt body 2 is passed out from the other end of the hole. The staff puts the grid nut into the main fixing bolt body 2 and then locks it through the thread. When locking, the positioning threaded hole 12 of the grid nut 3 can be matched with the positioning threaded hole 12 of the main fixing bolt body 2. The staff rotates the locking threaded bolt 7 of the anti-loosening fixture 5 in turn and passes it into the positioning threaded holes 12 of the two, thereby fixing it, and the other end of the locking threaded bolt 7 will pass out from the positioning threaded hole 12 at the left end of the main fixing bolt body 2.

[0022] Furthermore, the surface of the locking threaded bolt 7 is provided with a plurality of groups of small fixing holes 8 which are distributed in a laterally equidistant manner. The upper and lower ends of the small fixing holes 8 are through-type structures. Auxiliary clamping bolts 9 are inserted into the small fixing holes 8. When in use, the staff inserts the auxiliary clamping bolts 9 into the small fixing holes 8 on the locking threaded bolt 7, thereby fixing the left end of the locking threaded bolt 7 to prevent the left end of the locking threaded bolt 7 from coming out.

[0023] Differently, a plurality of groups of positioning threaded holes 12 are provided on the left and right ends of the main fixing bolt body 2 and on the outer side of the truss nut 3. The positioning threaded holes 12 are of a through structure, and the truss nut 3 is of an octagonal structure. The positioning threaded holes 12 on the truss nut 3 and the main fixing bolt body 2 are for facilitating the insertion of the locking threaded bolt 7 of the anti-loosening fixer 5, so as to be fixed using the anti-loosening fixer 4.

[0024] Effectively, the front end of the locking block 6 is sleeved with a fitting sealing block 10, which is annular and made of rubber. The fitting sealing block 10 can be fitted onto the grid nut 3, thereby improving the stability of the fixation.

[0025] Working principle: During operation, the staff inserts the main fixing bolt body 2 into the part fixing hole, and then the top of the main fixing bolt body 2 passes through the other end of the hole. The staff inserts the grid nut into the main fixing bolt body 2, and then locks it through the thread. When locking, the positioning threaded hole 12 of the grid nut 3 can be matched with the positioning threaded hole 12 of the main fixing bolt body 2. The staff rotates the locking threaded bolt 7 of the anti-loosening fixer 5 and passes it into the positioning threaded holes 12 of the two in turn to fix them, and the other end of the locking threaded bolt 7 will pass through the positioning threaded hole 12 at the left end of the main fixing bolt body 2. The staff inserts the auxiliary clamping bolt 9 into the small fixing hole 8 on the locking threaded bolt 7, thereby fixing the left end of the locking threaded bolt 7 to prevent the left end of the locking threaded bolt 7 from coming out.

[0026] The utility model includes 1. device body; 2. main fixing bolt body; 3. grid nut; 4. anti-loosening fixture; 5. rotating cover; 6. locking block; 7. locking threaded bolt; 8. small fixing hole; 9. auxiliary clamping bolt; 10. fitting sealing block; 11. anti-sliding block; 12. positioning threaded hole. All the components are universal standard parts or components known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. The utility model solves the problem that the existing nuts may fall off due to external factors during use, such as vibration force, which further affects the stability and safety of mechanical operation. The utility model can effectively ensure the stability between the nut and the bolt after installation through the combination of the above components, thereby preventing the nut and bolt from falling off.
