Abstract

The utility model relates to a car fuel sprayer sheath buckle detection device, including the power, the output of power is even to the one row of parallelly connected first buckle sheath that awaits measuring, second buckle sheath, third buckle sheath and fourth buckle sheath that awaits measuring that awaits measuring that awaits measuring, more than adopting behind the technical scheme: the utility model discloses a IC logic gate and the output of the 2nd IC logic gate link to the 3rd IC logic gate, and the 3rd IC logic gate matching principle is the same, if the input all be high pressure signal, then the output of the 3rd IC logic gate is for the high pressure, passes to proximity switch's negative pole, then at this moment proximity switch normally open the alarm stop work that the wiring was held, do not report to the police promptly, if a IC logic gate and the 2nd IC logic gate have the low pressure that is of an input, then the 3rd IC logic gate is then exported and also is low pressure, arrival proximity switch, and then the alarm is normally worked, reports to the police promptly, points out the installation mistake, and whether normally while LED pilot lamp has before played the instruction circumstances of route.

Description

A kind of automobile oil nozzle sheath buckle pick-up unit

Technical field

The utility model belongs to automobile oil nozzle line sheath buckle detection field, specifically belongs to a kind of automobile oil nozzle sheath buckle pick-up unit.

Background technology

Need in prior art to assemble metal buckle on the sheath of automobile oil nozzle, but for the assembling of metal buckle, normally detected by artificial mode, whether assemble correct, but artificial detection always there will be certain error.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of automobile oil nozzle sheath buckle pick-up unit.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

A kind of automobile oil nozzle sheath buckle pick-up unit, comprise power supply, the output terminal of described power supply connects to a row the first buckle sheath to be measured in parallel, second buckle sheath to be measured, 3rd buckle sheath to be measured and the 4th buckle sheath to be measured, described first buckle sheath to be measured, second buckle sheath to be measured, the output terminal of the 3rd buckle sheath to be measured and the 4th buckle sheath to be measured connects to a LED light respectively, the output terminal of described first buckle sheath to be measured and the second buckle sheath to be measured also connects to an IC logic gate, the output terminal of described 3rd buckle sheath to be measured and the 4th buckle sheath to be measured also connects to a 2nd IC logic gate, the output terminal of a described IC logic gate and the 2nd IC logic gate connects to a 3rd IC logic gate, the output terminal of described 3rd IC logic gate connects the negative pole to a proximity switch, the terminals of often opening of described proximity switch connect an alarm.

Described first buckle sheath to be measured, the second buckle sheath to be measured, the 3rd buckle sheath to be measured and the 4th buckle sheath to be measured are all that metal buckle is assembled to after on sheath, and sheath is installed assembly direction and is assembled on frock panel.

A described IC logic gate, the 2nd IC logic gate and the 3rd IC logic gate all adopt 74LS08 and door IC.

The LED light of the output terminal of described first buckle sheath to be measured, the second buckle sheath to be measured, the 3rd buckle sheath to be measured and the 4th buckle sheath to be measured is respectively by a resistance eutral grounding.

After adopting above technical scheme: the first buckle sheath to be measured and the second buckle sheath to be measured carry out matching and be connected to an IC logic gate simultaneously by the utility model, 3rd buckle sheath to be measured and the 4th buckle sheath to be measured are carried out matching and is connected to the 2nd IC logic gate simultaneously, one IC logic gate is identical with the 2nd IC logic gate principle of work, all that two buckle sheaths to be measured of access are contrasted, if the buckle sheath input to be measured of access is all high pressure, what so IC logic gate exported is high pressure, as long as what wherein have a buckle sheath input to be measured is not high pressure, what so IC logic gate exported is then low pressure, then an IC logic gate and the 2nd IC logic gate export and connect to the 3rd IC logic gate, 3rd IC logic gate matching principle is identical, if input is all high-voltage signal, then the 3rd IC logic gate exports as high pressure, pass to the negative pole of proximity switch, then at this moment the alarm often opening terminals of proximity switch quits work, namely do not report to the police, if what an IC logic gate and the 2nd IC logic gate had one to input is low pressure, then the 3rd IC logic gate then exports also is low pressure, arrive the words of proximity switch, then alarm normally works, namely report to the police, prompting setup error, LED light simultaneously is also serve the situation indicating whether regular path.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.
