Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting nuts, in particular to an automatic compensating double-protection connection nut for fire-fighting. Background Art

[0002] In the field of firefighting, there are many firefighting facilities. In these firefighting facilities, bolts and nuts are usually used when connecting components to make the components connected and fixed. The double-proof connection nut refers to preventing the bolt from loosening by the interaction of two nuts. By installing two nuts on the bolt, a space for relative movement is formed between the nuts. When the bolt is vibrated or subjected to external force, the relative movement between the nuts will generate friction, thereby preventing the bolt from loosening. However, when vibrated, a certain distance difference will be generated between the bolt and the nut, which is not convenient for automatic compensation. Therefore, an automatic compensation double-proof connection nut for firefighting is needed.

[0003] According to the design of the existing automatic compensation double-proof connection nut for fire fighting, when a distance difference occurs, it is necessary to manually tighten the compensation, which is not convenient for automatic compensation and makes it less suitable for use. Therefore, its structure needs to be improved.

[0004] Now, a new type of automatic compensating double-proof connection nut for fire fighting is proposed to solve the above-mentioned solution. Utility Model Content

[0005] The utility model aims to provide an automatic compensation double-proof connection nut for fire fighting, so as to solve the problem in the above-mentioned background technology that it is not convenient to automatically compensate when a distance difference occurs.
