Brief description of the drawings
Fig. 1 is a kind of structural representation of anti-loosening bolt proposed by the present invention.
Embodiment
Below, technical scheme is described in detail by specific embodiment.
As shown in figure 1, Fig. 1 is a kind of structural representation of anti-loosening bolt proposed by the present invention.
Reference picture 1, a kind of anti-loosening bolt that the embodiment of the present invention proposes, including：Screw rod 1, in the side wall of the screw rod 1
The body 2 being made by spring steel is provided with provided with axially extending groove, in groove, one end of body 2 is fixed with screw rod 1 to be connected
Connect, its other end is free end, and in its natural state, the body 2 close to the outer wall of the side of groove side and screw rod 1 it
Between there is spacing, and the spacing is incremented by successively from the fixing end of body 2 to its free end.
The present invention is that this is so used：After screw rod is through the workpiece for needing to connect, in upper cap nut, pass through pressing
Body 2 is pressed in groove by mode, and then fixing extreme direction from the free end of body 2 to it screws in nut, when nut passes through bullet
Push action to body 2 is unclamped behind the free end of body 2, to utilize its own resilient of body 2, makes the free end of body 2 to extending out
Exhibition, position is tilted to be upwardly formed in nut back-out side so that nut can not screw out, to stop that nut screws out.
From the foregoing, it will be observed that the present invention by setting groove on screw rod 1, sets body 2, and make the one of body 2 in groove
End is fixed with screw rod 1, and its other end is free end, and works as body 2 in its natural state, and it is close to the side of groove side and spiral shell
There is spacing between the outer wall of bar 1, and make the spacing incremented by successively from the fixing end of body 2 to its free end, in upper cap nut,
Body 2 is pressed in groove by way of pressing, then fixing extreme direction from the free end of body 2 to it screws in nut, when
Nut through unclamping push action to body 2 behind the free end of body 2, body 2 in its own resilient to external expansion, with spiral shell
Cap back-out side, which is upwardly formed, tilts position so that nut can not screw out, and good loosen dynamic effect so as to play.
In addition, in the present embodiment, body 2 is the contour body coaxially arranged with screw rod 1, side of the body 2 away from groove side
Face is provided with the first spiro tooth part that multiple short transverses along screw rod 1 are equally spaced, and the outer surface of screw rod 1 is provided with multiple along it
The second spiro tooth part that short transverse is equally spaced, and when body 2 and screw rod 1 are in same anchor ring, it is each on the body 2
First spiro tooth part is docked with each second spiro tooth part on screw rod 1 to form the thread risen around the axial line helical disk of screw rod 1, to pass through
The mode of pressing body 2 makes the first spiro tooth part be docked with the second spiro tooth part, so that the smooth precession of nut, with by unclamping body 2
Mode, deform thread, so that nut can not screw out, loosen dynamic effect so as to further improve.
In the present embodiment, be provided with compression spring 3 between body 2 and groove, the both ends of compression spring 3 respectively with body 2, recessed
Groove inwall connects, and when compression spring 3 in the raw when, the body 2 is close to the outer of the side of groove side and screw rod 1
There is spacing, and the spacing is incremented by successively from the fixing end of body 2 to its free end between wall, by body 2 and groove it
