Specific embodiment
The present invention is described in detail below in conjunction with attached drawing.
As shown in Figs. 1-3, a kind of self-locking fastener device, for screwing fastening by secure component 13, including bolt 0,
Lock washer 11, bolt 0 include screw rod 101 and the bolt head 102 for being arranged on 101 one end of screw rod, bolt head 102 and lock washer
11 can be used hexagon, and there is screw rod 101 screw thread to be screwed to by secure component 13.Lock washer 11 have upper surface and
Lower surface, lower surface is equipped with several strip projected parts 112, with being contacted and when screwing fastening by fastening part by secure component 13
13 surface of part generates embossing, increase friction.Lock washer 11 is equipped with centre bore 113, and lock washer 11 is worn by centre bore 113
On screw rod 101.Bolt head 102 has the bolt head inner surface that is contacted with 11 upper surface of lock washer, and screw rod 101 is from bolt
The center of first 102 bolt head inner surface extends out.The upper surface of lock washer 11 is equipped with first stinging for radially uniform distribution
Tooth 111 is closed, bolt head inner surface is equipped with the second tooth engaged 121 of radially uniform distribution, during assembling, 111 He of the first tooth engaged
Second tooth engaged 121 is mutually matched occlusion to lock.
First tooth engaged 111 and the second tooth engaged 121 are inclined-plane tooth, each first tooth engaged 111 has the first tooth
It is preced with the 1111, first bottom of the tooth 1112, the first backstop flank 1113, first slides flank 1114, the first crown 1111 and the first bottom of the tooth
1112 are distributed in 1114 both sides of the first slip flank, and the first slip flank 1114 inclines from the first crown 1111 to the first bottom of the tooth 1112
Tiltedly, the first backstop flank 1113 hangs down to the first bottom of the tooth 1112 of adjacent bevel surfaces tooth from the first crown 1111 so that first slides
There are one inclination angle alphas with horizontal plane tool for flank 11141.First backstop flank 1113 hangs down to adjacent oblique from the first crown 1111
First bottom of the tooth 1112 of face tooth so that the first backstop flank 1113 forms an angle beta with horizontal plane1.Each second occlusion
There is tooth 121 second crown 1211, the second bottom of the tooth 1212, the second backstop flank 1213, second to slide flank 1214, the second crown
1211 and second bottom of the tooth 1212 be distributed in 1214 both sides of the second slip flank, second slide flank 1214 from the second crown 1211 to
Second bottom of the tooth 1212 tilts, and the second backstop flank 1213 hangs down to the second bottom of the tooth of adjacent bevel surfaces tooth from the second crown 1211
1212 so that second slides flank 1214, and there are one inclination angle alphas with horizontal plane tool2.Second backstop flank 1213 is from the second tooth
Hat 1211 hangs down to the second bottom of the tooth 1212 of adjacent bevel surfaces tooth so that the second backstop flank 1213 and horizontal plane shape are at an angle
β2。
After assembling, the first slip flank 1114 and second slides flank 1214 and is bonded to each other, α1With α2Angle is equal.First
1113 and second backstop flank of backstop flank, 1213 mutual stop, β1And β2Angle is equal, generally easy to process, β1And β2Angle
Degree is preferably designed as 90 degree.
Hexagon can be used in bolt head 102 and lock washer 11, at this time the first tooth engaged 111 and the second tooth engaged 121
It it is 6, and each first tooth engaged 111 and each second tooth engaged 121 correspond to a hexagonal seamed edge.
During assembling, lock washer 11 is attached on screw rod 101, towards 102 direction of bolt head, lower surface is then reversed for upper surface,
Screw rod 101 is screwed by secure component 13,1213 mutual backstop of the first backstop flank 1113 and the second backstop flank, is screwed tight
Gu complete assembling.When encountering vibration, the second of the second tooth engaged 121 slides flank 1214 relative to the of the first tooth engaged 111
One slide 1114 slide displacement of flank, due to bolt head 102 carry tooth engaged and second slip flank 1214 have with horizontal plane
One angle of inclination, and slide flank 1114 with lock washer 11 first and coordinate, the second slip flank 1214 was loosened in vibration
It needs constantly to be lifted in journey, and reaches peak value being raised at 1211 docking of the first crown 1111 and the second crown, in this process
In, it needs constantly to continue to increase torsion, and usual irregular vibration can not provide and continue to increase torsion, thus bolt head 102
A lifting changing of the relative positions can not be completed to adjacent tooth position, entire fastening structure is able to continue fastening.
More than content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes, the content of the present specification should not be construed as to the present invention in specific embodiments and applications
Limitation.
