Instead.
Compared with prior art, the beneficial effects of the utility model are:
One kind provided by the utility model loosens prompt threaded fastener, can be when threaded fastener loosens
Time is made intuitive state and is changed, to prompt operating personnel's threaded fastener to have occurred that loosening.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the section structure that one of embodiment loosens prompt threaded fastener；
Fig. 2 is the present invention looks up structural representation that Fig. 1 removes rest part after fastening bolt.
Specific embodiment
Referring to figs. 1 to Fig. 2, Fig. 1 to Fig. 2 is the structural schematic diagram of one specific embodiment of the utility model.
As shown in Figure 1, one kind loosens prompt threaded fastener, including fastening bolt 1, fastening nut 2, prompt bolt 3, mention
Show that nut 4 and prompt nut cap, the fastening nut 2 are matched with the fastening bolt 1, the prompt bolt 3 is mentioned with described
Show that nut 4 matches, and the major diameter of the prompt bolt 3 is less than the path of the fastening bolt 1；The one of the prompt bolt 3
Hold it is axially disposed have a spin-ended bolt 5, one end of the fastening bolt 1 is axially disposed have the cooperation spin-ended bolt 5 only
Revolve slot 6；The prompt nut cap includes nut cap top plate 7 and nut cap sleeve 8, and the nut cap sleeve 8 is sleeved on the fastening nut 2
With the outside of the prompt nut 4, and the prompt nut 4 is between the nut cap top plate 7 and the fastening nut 2.Institute
Stating spin-ended bolt 5 can not be circular column structure for any bottom surface, as long as can guarantee the prompt bolt 3 relative to institute
Fastening bolt 1 is stated not rotate.
A kind of above-mentioned working principle for loosening prompt threaded fastener is: when the fastening nut 2 loosens,
The prompt nut 4 is driven to rotate, the prompt bolt 3 is towards the end face of the nut cap top plate 7 to the prompt nut 4
End face on the outside of stretch out, to jack up the nut cap top plate 7, the prompt nut cap is made to fall off, to prompt the fastening bolt 1
Have occurred that loosening.
In order to make prompt nut cap stable connection when the fastening bolt 1 does not loosen, and it is easy to fall off in instruction:
Preferably, the medial surface of the nut cap sleeve 8 is provided with detent protrusion 9, and the lateral surface of the fastening nut 2 is provided with cooperation institute
State the retaining groove 10 of detent protrusion 9.The detent protrusion 9 and the retaining groove 10 are hemispherical dome structure.
According to above-mentioned principle, as it will be apparent to those skilled in the art that one kind provided in this embodiment loosens prompt spiral shell
Line fastener should also meet claimed below in a state of use:
The end face and the abutting nut cap of the prompt bolt 3 and the prompt nut 4 towards the nut cap top plate 7
