Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.
As shown in fig. 1, the utility model provides an anti-drop structure, which comprises an adjusting nut 1, a bolt 2, a blind rivet nut 3, a first assembly part 6 and a second assembly part 4, wherein a certain gap is formed between the adjusting nut 1 and the first assembly part 6, and a gasket 5 is arranged between the adjusting nut 1 and the blind rivet nut 3.
The adjusting nut 1 comprises an adjuster 11, a retainer 12, a spring 13 and a bracket 14. The spring 13 has a hollow cylindrical shape, is inserted into the regulator 11, and is connected to the regulator 11. The adjuster 11 and the holder 12 are connected by reverse threads. The retainer 12 is inserted into the bracket interior 14 and connected to the bracket 14. The bracket 14 is connected to the second fitting 4. The bracket 14 is provided with claws 141 at both ends.
A gasket 5 is arranged between the adjusting nut 1 and the blind rivet nut 3. The gasket 5 is in an oblong shape, a round through hole is formed in the middle of the gasket, and clamping holes are formed in the two ends of the gasket. The round through hole is used for a bolt to pass through, and the clamping hole and the clamping claw 141 are matched to realize clamping connection of the gasket 5 and the bracket 14. Furthermore, the claw 141 is also inserted into the through hole 41 of the second fitting 4 to achieve the connection of the bracket 14 and the second fitting 4.
In the process of tightening the bolt 2, due to interference fit between the bolt 2 and the reed 13, the bolt 2 gives an acting force to the adjusting nut 1, the adjuster 11 is connected with the fixer 12 through reverse threads, under the acting force of the bolt 2, the adjuster 11 is screwed up and fills a gap between the adjusting nut 1 and a first assembly part, the adjuster is abutted against the first assembly part, then the bolt 2 is tightened in cooperation with the rivet nut 3, the bolt 2 is screwed down gradually, and the gasket 5 prevents the rivet nut 3 from moving upwards.
Because the gasket 5 is arranged between the adjusting nut 1 and the blind rivet nut 3, the gasket 5 can prevent the blind rivet nut 3 from moving upwards in the process of tightening the bolt 2 and the blind rivet nut 3 in a matching manner, and therefore, the anti-falling structure can prevent the blind rivet nut from moving upwards under stress in the process of tightening the bolt.
As shown in fig. 2, the separation preventing structure according to the second embodiment of the present invention is different from the separation preventing structure shown in fig. 1 in that a spacer 5 and a holder 12 are integrally formed, and the other structure is the same as that of the first embodiment.
As shown in fig. 3, the separation preventing structure according to the third embodiment of the present invention is different from the separation preventing structure shown in fig. 1 in that a washer 5 and a holder 12 are screw-coupled, and the other structure is the same as that of the first embodiment.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
