Complete to fix using bolt is tightened manually, and whether bolt is installed in place to effectively realizing that functions of the equipments have decisive influence.
Since working space is limited, and high radioactivity environment is in, directly observes or detect bolt to bit comparison using conventional tool
It is difficult.In addition for reduction personnel by according to dose of radiation, it is desirable to worker is completed within the short time as far as possible installation and review.Therefore, need
A kind of not only reliable but also convenient mode is wanted to check bolt whether in place.
The content of the invention
The purpose of this utility model is to provide a kind of bolt of band detection function in place, it can reliably, simply judge
Bolt situation in place.
The technical solution of the utility model is as follows：A kind of bolt of band detection function in place, the bolt include screw rod and arrive
Position detection part, wherein, the off-center threaded shank portion of nut is provided with through hole in screw rod, and is equipped with the through hole and examines in place
Part is surveyed, the end portion of detection part in place protrudes the lower face of nut in screw rod, after screw rod is installed in place, bolt
Setting-up piece and the end portion of detection part in place are extruded, make in place detection part provide luminous instruction.
The detection part in place includes indicator light, battery, shell, spring and contact switch, wherein, indicator light and
Contact switch is separately fixed at shell upper and lower ends；Battery is located at enclosure with spring, and is compressed battery admittedly using spring
It is scheduled between indicator light and contact switch, indicator light, battery and contact switch is formed circuit loop.
The battery cathode is in contact with indicator light anode, one end that anode passes through power spring and contact switch
Contact electrode；The other end of the contact switch is directly connected by conducting wire with indicator light cathode.
It is helicitic texture outside the detection part in place, itself and the helicitic texture phase in through hole in bolt and nut
Match somebody with somebody.
The indicator light is LED light.
The shell is cylindrical structure.
The spring is conductive metal material.
The contact switch is fixed on shell lower end, and the switch button of contact switch protrudes the lower face of shell.
The battery cathode is in contact with indicator light anode, one end that anode passes through power spring and contact switch
Contact electrode；Another termination electrode of the contact switch is connected by the shell of conductive material with indicator light cathode.
The detection part in place is cylindrical structural, itself and it is logical in the off-center threaded shank portion of nut in screw rod
Hole matches.
The remarkable result of the utility model is：A kind of bolt arrangement of band described in the utility model detection function in place
Simply, bolt fixed function is not influenced, and in-site installation is simple；Sensor is not required in it, it is not required that signal processing, circuit are reliable
It is anti-interference, conventional environment is can be not only used for, and can be used for nuclear radiation environment；Bolt state in place is directly characterized by indicator light, is tied
Fruit is clear, directly perceived.
