With the supporting element 2, to keep the combination shape of the locking teeth 121 of the locking piece 1 and the axial peripheral surface of fastener 4
State.In this way, fastener 4 cannot be moved back from screw rod pine, so that it is guaranteed that being fastenedly connected.
In one embodiment, in order to allow each fastener locking device to prevent the loosening of two fasteners 4 simultaneously,
Each fastener locking device includes two locking pieces 1, and two locking pieces 1 are locally folded in described pairs of away from one another
Supporting element 2 between, be folded between the adjacent end of two locking pieces 1 between the pairs of supporting element 2 and have
There is gap 6, the keyed end 12 of the locking piece 1 extends to except the pairs of supporting element 2.Gap 6 play avoid two it is adjacent
The effect that interferes in the course of rotation of locking piece 1.
As depicted in figs. 1 and 2, the fastener locking device of the utility model embodiment can be directly installed on wheel 200
Discoidal spoke 9 on.Spoke 9 is equipped with multiple fourth holes, the nut as fastener 4 and the spiral shell across fourth hole
Bolt combines, and wheel is mounted on the wheel hub of wheel.During the installation process, wheel 200 will can be pacified using fastener 4 first
On the wheel hub of wheel, and tightening fastener parts 4；Later, pairs of supporting element 2 is mounted on spoke 9；Later, it will lock
The pivot part 11 of part 1 is placed between pairs of supporting element 2 and is rotatablely connected by pivot 111 and supporting element 2；Adjust locking piece
1, so that the locking teeth 121 of locking piece 1 and the axial peripheral surface of fastener 4 is combined closely, institute is then connected using retainer 3
Locking piece 1 and the supporting element 2 are stated, it will not be up and down after combining locking piece with fastener 4.In the case, fastener 4
Tooth 421 and the locking teeth 121 of locking piece 1 be securely abutted together, to achieve the purpose that prevent fastener 4 from rotating.?
In a kind of embodiment, fastener 4 has square prism shape, regular hexagonal prism shape or quincunx outer surface.As Fig. 2,3,4,7,8,
9, shown in 10 and 11, fastener 4 includes nut, is bolt, the screw flight cooperation of nut and the bolt by fastener.Nut
It can be tetragonal nut, hex nut or horned nut.In another embodiment, as shown in Fig. 5,6,12 and 13, fastening
Part 4 includes the bolt being made of bolt head and screw rod, and the bolt head and screw rod integrally connected simultaneously rotate together.Bolt head can be with
It is quadrangle bolt head, hexagonal bolt head or plum blossom bolt head.As shown in figures 19-22, the fastener 4 includes: regular prism portion
Points 41 and round flange 42, round flange 42 integrally protruded radially outward from one end of the regular prism part 41, institute
The peripheral surface for stating round flange 42 is equipped with multiple teeth 421, and the multiple tooth 421 in axial direction extends, and described more
A tooth 421 is separably combined with the locking teeth 121 of fastener locking device.When fastener 4 is bolt, screw rod is set to circle
One end away from the regular prism part 41 of flange 42, in the embodiment shown in Figure 21 and Figure 22, screw rod is set to round convex
On the bottom surface of edge 42.When fastener 4 is nut, through-hole or corresponding with the screw thread of nut is additionally provided on round flange 42
Threaded hole, so as to pass through being threadedly engaged for round flange 42 and nut with the screw rod of nut cooperation.Shown in Figure 19 and Figure 21
Embodiment in, multiple teeth 421 axially penetrate through the round flange 42 namely multiple teeth 421 along the round flange 42
Thickness is equal to the thickness of the round flange 42.
In one embodiment, the locking teeth 121 of the tooth 421 on the round flange 42 of fastener 4 and locking piece 1 is matched
It closes, forms anti-loose structure.Tooth 421 circumferentially, and is formed as multiple straight-tooth or square type odontoid；Tooth 421 and locking teeth 121
Can be engaged, thus fastener 4 is prevented to rotate.Height or institute of the height of the locking piece 1 beyond round flange 42
The thickness for stating locking teeth 121 is greater than the height of multiple teeth 421 of the round flange 42 in the axial direction, in locking piece 1
When generating axial movement relative to fastener 4, multiple teeth 421 of round flange 142 and it still is able to the locking teeth with locking piece 1
121 combine.No matter round flange 42 is in any angle can cooperate with locking piece 1, to prevent fastener 4 from rotating.Locking teeth
121 and fastener 4 multiple teeth 421 in addition to simultaneously for matched straight-tooth or rectangular gear other than, can also be suitable for other simultaneously
Flute profile.Two kinds of embodiments of the clamp device when locking teeth 121 of Fig. 6 and respectively locking piece 1 shown in Fig. 9 is rectangular teeth
Schematic diagram, a kind of schematic diagram of embodiment of the locking piece 1 shown in figure 15 when be the locking teeth 121 of locking piece 1 being rectangular teeth,
When the locking teeth 121 for shown in Figure 20 and Figure 22 being locking piece 1 is rectangular teeth, the tooth 421 of corresponding fastener 4 is also rectangular teeth
Two kinds of embodiments schematic diagram.It is rectangular teeth embodiment in the tooth 421 of locking teeth 121 and fastener 4 that these determine part 1
In, as shown in figure 15, the quantity of the locking teeth 121 of locking piece 1 is 1 tooth, as shown in Figure 20 and Figure 22, the tooth 421 of fastener 4
Depth be less than round flange 42 thickness.
