Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of anti-backspin bolt, including screw rod 1 and nut 2, the nut 2 are equipped with screw hole
3, stop assembly is further included, the stop assembly includes atopping sleeve 4, axis pin 5 and stop bit bar 6, and the screw rod 1 is equipped with length
Groove 7, the nut 2 are equipped with the connection ring 8 concentric with nut 2, and 8 outer ring of connection ring is equipped with external screw thread, institute
4 axle center of atopping sleeve stated is equipped with connecting hole 14, and atopping sleeve 4 is equipped with the translot 9 through 4 upper and lower end face of atopping sleeve, described
Internal thread is equipped with connecting hole 14, the atopping sleeve 4 is threadedly coupled with connection ring 8, and the axis pin 5 is fixed in translot 9,
Described 6 one end of stop bit bar is equipped with pin hole 10, and stop bit bar 6 is rotatably connected with axis pin 5, and the other end, which has, protrudes from screw hole 3 one
The jag at end, the length of the jag are less than the depth of elongated slot.
When in use, stop bit bar 6 is overturn to the periphery of atopping sleeve 4, the nut 2 that set is installed to atopping sleeve 4 fastens
On to screw rod 1 and restraint location is screwed into, then adjusting the position of atopping sleeve 4 makes stop bit bar 6 be directed at elongated slot 7, afterwards turns over stop bit
Bar 6 is caught in elongated slot 7.Under the action of stop bit bar 6, can effectively prevent nut loosen backspin, improve fastening security and
Stability.
In the utility model, the axis pin 5 is arranged in the translot 9 of 4 outer ring of atopping sleeve；Outside the stop bit bar 6
Snare rubber sleeve 11；The translot 9 is two, and the opposite both ends for being arranged on atopping sleeve 4, stop bit bar 6 is turned to nut
When outer ring, stop bit bar 6 can be used as spanner, can be provided great convenience when strap wrenches is forgotten, also side
Just atopping sleeve 4 is rotated to the connection ring 8 of nut 3；It is relatively thin additionally, due to stop bit bar 6, when being used as spanner, behaviour
Excessively firmly hand has more obvious feeling of pain to author, and the rubber sleeve in 6 outer ring of stop bit bar can reduce the hardness of stop bit bar,
And then the feeling of pain of operator is reduced, contribute to operator to make power.
In the utility model, the jag is equipped with magnet 12, and magnet 12 can adsorb stop bit bar 6 in elongated slot
In 7, prevent stop bit bar 6 in 2 lower face of nut and free-falling does not have braking action, it is notable that use when
Wait, problem above can be prevented by the end face of 4 side of atopping sleeve upward；Set on the stop bit bar of described 10 one end of pin hole
