[0023] The following will be combined with 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 of 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.

[0024] Example 1

[0025] like Figure 1~Figure 5 As shown, the present embodiment proposes a bolt assembly capable of preventing the connection from being loosened, comprising an assembly column 1, wherein the two ends of the assembly column 1 are respectively fixedly connected with a transmission block 2 and a threaded column 3, a locking cavity 4 is provided inside the assembly column 1, a limiting cavity 5 is provided inside the threaded column 3, a nut assembly 6 is provided outside the threaded column 3, the nut assembly 6 comprises a mounting plate 7, an assembly block 8 and a stabilization assembly, the mounting plate 7 is slidably connected inside the locking cavity 4, the mounting plate 7 is rotatably connected outside the mounting plate 7, and the assembly block 8 is also threadedly connected to the threaded column 3, a stabilization assembly is fixedly connected to the middle of the mounting plate 7, and the stabilization assembly is used to cooperate with the locking cavity 4 to lock the position of the assembly block 8;

[0026] In detail, both sides of the carrying plate 7 are fixedly connected with extension blocks, an arc-shaped carrying groove is opened in the middle of the extension block, and the assembly block 8 is rotatably connected inside the arc-shaped carrying groove. By setting the extension block, a stable assembly of the assembly block 8 can be formed to ensure the application effect of the assembly block 8;

[0027] Furthermore, an anti-dropping block is fixedly connected to the inner side of the arc-shaped carrying groove, an anti-dropping groove is provided at one end of the assembly block 8 close to the anti-dropping block, and the anti-dropping block is also slidably connected to the inside of the anti-dropping groove. Since the anti-dropping block is located inside the anti-dropping groove, the assembly block 8 can be effectively restricted to prevent the assembly block 8 from detaching from the extension block.

[0028] Preferably, both sides of the threaded column 3 are provided with avoidance grooves for avoiding the extension block. By setting the avoidance grooves, the extension block can pass through the avoidance grooves, and when the assembly block 8 is connected to the threaded column 3, the displacement of the assembly block 8 will not be interfered with;

[0029] Among them, the side of the assembly column 1 and the assembly block 8 close to each other is fixedly connected with an anti-skid pad, and the outer side of the anti-skid pad is provided with an anti-skid pattern. By setting the anti-skid pad, when the assembly column 1 and the assembly block 8 contact with the external gasket, the friction force with the gasket can be effectively increased to prevent the assembly column 1 and the assembly block 8 from loosening;

[0030] A threaded through hole is provided in the middle of the assembly block 8, and the assembly block 8 is connected to the threaded column 3 through the threaded through hole;

[0031] Example 2

[0032] like Figure 1~Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a stabilization component;

[0033] In this embodiment, the stabilization component includes a stabilization sleeve 9, a stabilization shaft 10, a pressure plate 11, a coil spring 12, a transmission screw 13 and a guide column 14. The middle part of the mounting plate 7 is fixedly connected to the stabilization sleeve 9, and the stabilization shaft 10 is slidably connected to both sides of one end of the interior of the stabilization sleeve 9, and the stabilization shaft 10 is also connected to the locking cavity 4 by a card connection. The end of the stabilization shaft 10 located inside the stabilization sleeve 9 is fixedly connected to the pressure plate 11, and the coil spring 12 is fixedly connected between the pressure plate 11 and the inner wall of the stabilization sleeve 9. The middle part of the other end of the stabilization sleeve 9 is rotatably connected to the transmission screw 13, and the outer side of the transmission screw 13 is threadedly connected to the guide column 14. The outer side of the guide column 14 is fixedly connected to a limiting disk 15, and the limiting disk 15 is also slidably connected to the stabilization sleeve 9, and the end of the guide column 14 close to the pressure plate 11 is fixedly connected to a deflection plate 16 for squeezing the pressure plate 11;

[0034] Furthermore, a plurality of locking holes are provided inside the threaded column 3, and the stabilizing shaft rod 10 is connected to the inside of the locking holes.

[0035] In detail, one end of the transmission screw 13 located outside the stabilizing sleeve 9 is fixedly connected to a force knob, and a transmission groove is opened in the middle of the force knob. The transmission groove is polygonal. By using the force knob, personnel can easily drive the transmission screw 13 for transmission, thereby ensuring the transmission efficiency of the transmission screw 13;

[0036] Furthermore, the pressure plate 11 is obliquely fixedly connected to one end of the stabilizing shaft rod 10 located inside the stabilizing sleeve 9, and both ends of the push plate 16 are provided with extrusion surfaces adapted to the inclined surface of the pressure plate 11, and a wear-resistant layer is provided on the extrusion surface. By using the setting of the extrusion surface, the stabilizing shaft rod 10 can be pushed out of the stabilizing sleeve 9 and clamped with the threaded column 3 through the linear displacement of the push plate 16;

[0037] A specific application of the above two embodiments is to first connect the assembly block 8 with the threaded column 3, and rotate the assembly block 8 so that the assembly block 8 moves on the outside of the threaded column 3, and when the assembly block 8 moves, the mounting plate 7 will slide adaptively inside the threaded column 3, and move the stabilizing sleeve 9 into the locking cavity 4. When the assembly block 8 reaches the specified position, the transmission screw 13 is rotated, and the transmission screw 13 is connected with the guide column 14, so that the guide column 14 drives the push plate 16 to squeeze the pressure plate 11 under the limit of the limit plate 15, so as to prompt the stabilizing shaft 10 to move out of the stabilizing sleeve 9 and get stuck in the locking cavity 4, thereby forming a locking of the position of the stabilizing sleeve 9. Since the position of the stabilizing sleeve 9 is locked, the assembly block 8 can be limited to prevent the assembly block 8 from loosening.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
