Air-pressure power supply alarming lamp

Abstract

The invention provides an air-pressure power supply alarming lamp, comprising a lamp holder and a transparent outer cover, wherein the upper surface of the lamp holder is provided with a cylindrical LED (Light-emitting Diode) indicator lamp and an AC / DC (Alternating Current / Direct Current) converter, which are arranged inside the transparent outer cover; the upper part of the lamp holder is a cylindrical lug boss which is arranged inside the transparent outer cover; the lug boss is arranged in the LED indicator lamp and the middle part of the lug boss is provided with an air cylinder; the front part of the air cylinder is penetrated into the bottom of the lamp holder; a plug is mounted at an opening of the front end of the air cylinder and an air inlet which is communicated with the air cylinder is arranged on the plug; the air cylinder is internally provided with a piston and a piston push rod; the piston is connected with the lower end of the piston push rod and the piston push rod is sleeved with a restoring spring; the upper end of the piston push rod extends out of the top of the lug boss; the top end of the piston push rod is further provided with an umbrella-shaped cap with a striking color and the umbrella-shaped cap is arranged in the LED indicator lamp; the cylindrical LED indicator lamp can emit light to indicate used power; and the piston in the air cylinder can be pushed forwards by high-pressure gas or can return under the effect of the spring when the air pressure is reduced, so as to indicate the used high-pressure gas.

Description

technical field [0001] The invention relates to a warning device, in particular to an air pressure and power supply warning light used on pneumatic electrical equipment or training platforms. Background technique [0002] At present, in the teaching of mechanical and electrical equipment related majors in ordinary universities and higher vocational colleges, in addition to traditional professional theoretical courses, the professional courses set up have different degrees of professional practice courses, which requires a lot of combination of actual production and engineering projects. The current training devices mainly include pneumatic and electrical training platforms. [0003] Using the pneumatic and electrical training platform for practical training is to install electrical energy and pneumatic components on the mounting plate of the training platform, and use power supply, high-pressure air source and components to connect according to the working principle for prac...

AI Technical Summary

Problems solved by technology

However, the existing training platform is only equipped with a light-emitting diode to display the power consumption. The display is not eye-catching, and it cannot display the high-pressure gas consumption. If the training personnel are negligent, it is easy to cause safety accidents

Since there is no high-pressure air source indicator light, it is easy to forget to turn off the air source after the experiment is completed, which will not only reduce the service life of the equipment, but also cause safety accidents when ventilating for a long time
