[0016] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.

[0017] like Figures 1 to 4As shown, an adjustable nut mounting assembly of this embodiment includes a main body 1, a nut 2 is arranged in the main body 1, the main body 1 has a through hole 11, and the through hole 11 has a first opening 111 and a second opening 112. A convex ring 12 is arranged in the through hole 11, and a first accommodating chamber 13 is formed between the convex ring 12 and the second opening 112. A limiting plate 14 is arranged in the first accommodating chamber 13, and a plurality of limiting plates 14 are arranged at intervals. A matching surface 21 is arranged on the outer wall of the nut 2, and the matching surface 21 corresponds to the limiting plate 14, so that the nut 2 cannot rotate in the first accommodating chamber 13. There is a gap between the limiting plate 14 and the matching surface 21, and the upper end 22 of the nut 2 corresponds to the convex ring 12. The first opening 111 has an extension portion 113, and the extension portion 113 is arranged around the main body 1, and the main body 1 is cylindrical. A groove 15 is arranged on the outer wall of the main body 1, and the groove 15 is axially arranged, one end of the groove 15 is connected to the extension portion 113, and the other end is a free end. In the above technical scheme, when the adjustable nut mounting assembly is in use, the main body 1 is first inserted into the through hole of the first part 10, the through hole can be a smooth hole, and the extension part 113 is against the first part of the device; the tool 30 is inserted through the first opening 111, the screw 301 of the tool 30 is threadedly connected with the nut 2, and the tool 30 is rotated. Since the nut 2 cannot rotate in the first accommodating chamber 13, it can move upward along the axial direction of the main body 1 and press the convex ring 12; since a groove 15 is provided on the thin wall of the main body 1, it is deformed after being subjected to axial pressure to form an outer protrusion 16, and the first part 10 is clamped by the extension part 113 and the outer protrusion 16, so that the main body and the first part 10 can be connected; then the second part 20 is connected to the first part 10 by a bolt 40. When the position of the bolt deviates from the nut, since there is a gap between the nut and the limit plate 14, the bolt 40 can be made to correspond to the nut by fine-tuning the nut position. Through the above technical solution, parts can be connected by bolts without the need to set screw holes, which facilitates assembly; in addition, the position of the nut can be adjusted to avoid installation failure due to dimensional deviation.

[0018] In this embodiment, the end face of the convex ring 12 is a bevel 121, and the upper end 22 of the nut 2 has a matching surface 221, and the matching surface 221 is arranged corresponding to the bevel 121, so that the matching surface 221 and the bevel 121 are squeezed. A second accommodating cavity 17 is provided between the first opening 111 and the convex ring 12, and the tool 30 is inserted into the second accommodating cavity 17 and pressed against the convex ring 12. The limit plate 14 has a flat surface 141, which is arranged toward the central axis of the main body 1, and the flat surface 141 corresponds to the mating surface 21 of the nut 2, so that the nut 2 can be prevented from rotating. There are four limit plates 14, and there are four mating surfaces 21, which are arranged corresponding to the flat surface 141. There is a bending portion 18 between the nut 2 and the second opening 112. After bending, the inner diameter of the second opening 112 is smaller than the diameter of the nut 2, so that the nut 2 can be positioned in the first accommodating cavity to prevent it from falling out. There are a plurality of grooves 15 , and the plurality of grooves 15 are arranged at intervals, so that the first part 10 is fixed more firmly.

[0019] An adjustable nut mounting assembly of the present embodiment enables parts to be connected by bolts without the need for screw holes, thereby facilitating assembly; in addition, the position of the nut can be adjusted to avoid installation failure due to dimensional deviation.

[0020] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
