Specific embodiment
With reference to embodiments of the invention, the invention will be further elaborated.
Fig. 1 shows the schematic diagram of quick detection fastener elasticity, and wherein a is relaxed state, and b is tight condition；
Optical signalling layer 4 is added between the connected piece 2 of fastener 1 and first and the second connected piece 3, wherein optical signalling layer is by with seam
Gap supporting layer and optical material are constituted；Under fastener coming loose state, the gap with gap supporting layer is larger, and optical material sends
Optical signal can be observed, optical signalling layer have optical signal；In the state of fastener is tightened, the seam with gap supporting layer
Gap diminishes, and the optical signal that optical material sends is difficult to observe or can not observe, optical signalling layer optical signal is weak or unglazed
Signal.
Embodiment 1：
In the present embodiment, it with spring is band gap supporting layer 5 that optical signalling layer 4 is, reflecting coating is used as optical material
6, optical material 6 is supported on the cylinder of fastener 1 with spraying method.If fastener is in relaxed state, spring gap is larger,
Substantial amounts of external irradiation light can be shone on reflecting coating, reflecting coating reflected light is more, and naked eyes are it can be seen that reflecting coating
Reflected light；If fastener be in tight condition, spring gap very little, exterior light can not or only a small amount of ambient light to instead
On optical coating, reflecting coating reflected light is less, and naked eyes are not it is observed that the reflected light of reflecting coating.Under ambient light, lead to
Can naked eyes be crossed see that reflected light just can quickly judge whether fastener is tightened, and then the fastener in relaxed state is carried out
Reinforce, to ensure that the An Quan such as machinery, equipment ﹑ reliably run.
Embodiment 2：
In the present embodiment, optical signalling layer 4 is that the pad processed with multiple-level surface roughening is band gap supporting layer 5,
Fluorescent material is made pad pasting and pastes on the cylinder of fastener 1 as optical material 6, wherein fluorescent material 6.If fastener is in
Relaxed state, due to being processed by rough surfaceization, the gap between pad is larger, and a large amount of external excitation light can be irradiated to fluorescence
On material, the fluorescence that fluorescent material is launched is more, and naked eyes are it can be seen that fluorescence；If fastener is in tight condition, pad
Between gap very little, external excitation light can not or only a small amount of external excitation luminous energy be irradiated on fluorescent material, fluorescent material hair
The fluorescence of injection is few, visually cannot see that fluorescence.Under the irradiation of outside exciting light, can see that fluorescence just can be quick by naked eyes
Judge whether fastener is tightened, and then the fastener in relaxed state is reinforced, to ensure the An Quan such as machinery, equipment ﹑
Reliable operation.
