Abstract
The utility model discloses an anti-detaching bolt. A longitudinal groove is arranged on the surfaces of screws of the common bolt, and the groove is from shallow to deep along the screw-in direction of the screws. After the tightening extent that a nut screws in reaches requirements, a pin is inserted in the groove, and the exposed part of the pin can be cut off. The nut can not screw inversely under the action of strong outer force, and thus, the anti-detaching purpose can be reached. When the nut need to fasten again, the nut can continue to screw in, and the nut is not affected.
Description
The utility model relates to a kind of nti-removing nut bolt.
Bolt is a kind of fastening piece that has wide range of applications, as long as corresponding nut is just screwed in and fastened thing can be clamped, uses easily.But in use, sometimes owing to artificially its dismounting being produced unsafe factor even having an accident.
Task of the present utility model provides a kind of nti-removing nut bolt.
Task of the present utility model is finished like this: promptly open a groove longitudinally in the thread surface of plain bolt, groove along the screw-in direction of screw thread from shallow to deep.With corresponding nut screw in make fastened thing meet the requirements of fastening degree after, a pin is inserted groove and clips its exposed parts, just can make the nut all can't derotation under bigger external force effect.And when the external force of using is excessive, will be with thread damage, nut also can't withdraw from derotation.
Because the utility model all can't withdraw from nut from derotation on the bolt under bigger external force effect, thereby can prevent that bolt and nut from being dismantled artificially, reach anti-purpose of unloading.
Below in conjunction with accompanying drawing and embodiment shown in the drawings model utility is further described, but the content of model utility is not limited thereto.
Accompanying drawing 1 is the side view of nti-removing nut bolt
Accompanying drawing 2 is the plan view of nti-removing nut bolt
The relative position of each part when accompanying drawing 3 is finished tightening state for the nti-removing nut bolt.
(1) is bolt among the figure; (2) be nut; (3) be pin; (a) be the groove on bolt surface.
As shown in the figure, after nut (2) screw-in bolt (1) makes it to meet the requirements of fastening degree, with darker position in the groove (a) on pin (3) inserting bolt (1) surface, and clip its exposed parts, bolt (1) and nut (2) have promptly reached fastening purpose.As with nut (2) derotation, pin (3) drive to be squeezed more shallow position in the groove (a) by screw thread, nut (2) promptly is stuck, derotation power is big more, pin is squeezed tightly more, thereby more can't screw out, and then can cause screw thread to be damaged when external force is excessive, nut (2) also just can not screw out, thereby finishes anti-task of unloading.And when nut (2) need to continue screwed in, pin (a) was taken to the depths of groove (a) by screw thread, and nut (2) still can screw in realizes the function that tightens up.
Therefore the utility model can be used on open-air or the unwatched fastened thing widely owing to have anti-function of unloading, and guarantees the safe handling of fastened thing.
