Description

Work lighting apparatus with gas detection function {Work lighting apparatus with gas detection function}

The present invention relates to a lighting device for work with a gas detection function that enables smooth work by providing bright light when work is performed in a dark and closed place.

In general, in closed workplaces where the inside is sealed due to disconnection from the outside, such as inside pipelines, inside tanks, inside ship docks, and water collection tanks, suffocation disasters due to lack of oxygen occur frequently without smooth inflow and circulation of air. It happens.

Although various countermeasures and equipment are prepared to prevent suffocation accidents occurring in such closed workplaces, deaths due to suffocation accidents are not easily reduced.

Here, among the various causes of suffocation, non-compliance with safety rules such as not performing gas measurement before and during work in an enclosed workplace appears to be the biggest cause.

That is, if a gas measuring device provided to prevent suffocation is always carried and gas measurement is performed without fail before and during work, death due to suffocation can be greatly reduced.

On the other hand, since most closed workplaces are narrow and dark environments, workers carry out work with a lighting device for work. Then, if the structure for the gas measurement function is applied to the lighting device for work, safety rules that must be performed before and during work can be naturally followed, so that the effect of preventing a suffocation disaster can be expected.

Thus, a multi-function lighting device for work in which a gas measuring function for measuring the concentration of various harmful gases is added to the lighting device for work has been developed.

A work lighting device with such a gas detection function includes a work lamp used for work in the main body, a gas sensor that detects the concentration of harmful gases, an emergency lamp used for emergency situations according to the concentration of harmful gases detected by the gas sensor, and electric energy It has a form that includes a battery that supplies

However, since the main body of a conventional lighting device for work with a gas detection function has only a shape worn on the body by the operator or only a shape that the operator can grip on the hand, one must be selected and used in advance according to the workplace environment, so various workplace environments For this, there is a problem of having to have all the different types of use.

In addition, the conventional work lighting device with a gas detection function is equipped with a single battery, and the electric energy supplied from the battery to the work lamp and the emergency lamp is not distinguished from each other, so when the battery is discharged due to long-term work, the gas is discharged. There is also a problem of not being able to prepare for an emergency situation because it is impossible to use a sensor and an emergency lamp.

Therefore, in order to ensure smooth operation and increase work efficiency, and to effectively prevent suffocation by demonstrating its function in emergency situations, it can be transformed into various forms to suit the working environment, so that even if equipped alone, it can be adapted to various working environments. There is an urgent need for the development of a lighting device for work that has a gas detection function that can respond properly and can properly perform gas detection and emergency notification functions by distinguishing regular power and emergency power from each other.

Republic of Korea Patent Registration No. 10-2171493, 2020.10.29.

Next, the connection holder 50 and the handle 60 are integrated so that the main body 10 and the light emitting module 40 can be separated so that the user can connect and use the main body 10 and the light emitting module 40 as needed. can be connected with

That is, the connection holder 50 enables the plurality of light emitting modules 40 to be integrally connected to one side of the main body 10, and the handle 60 is detachably connected to the end of the connection holder 50, so that the main body ( 10) and the light emitting module 40 are integrally connected and can be used while being held by the hand in the form of a flashlight.

To this end, the connection holder 50 is formed on one side of the holder body 51 to which one side and the other side are detachably coupled, as shown in FIGS. 4 and 5, and the holder body 51 is coupled. Accordingly, the restraint end 52 connecting the end of the handle 60 by insertion and restraint, and the fastening means 53 formed on one surface of the other side of the holder body 51 in a state in which one surface of the main body 10 is in close contact with each other A pair of left and right pivoting arms 55 connected to both sides of the other side of the other side of the holder body 51, respectively, and a left and right pivoting arm 55, each installed at the end of the close fixing end 54 fixed to, and a hinge on one side A connecting rod 57 in which rods 56 are installed in two vertical rows, and a plurality of detachable ports 58 installed in three vertical rows on the connecting rod 57 via the hinge rod 56 and with light emitting modules 40 detached from each other may consist of

Here, the left and right pivoting arm 55 is rotatably connected to the other surface of the holder body 51 and the release port 58 is rotatably connected up and down to the connecting rod 57 via the hinge rod 56. .

And, as shown in FIG. 2, the handle 60 is made of a cylindrical shape with a rounded outer circumferential surface so that it can be gripped by the hand, and is attached to the holder body 51 via the restraining end 53 provided at the end of the holder body 51. Can be detachably connected.

Therefore, the connection holder 50 connects the light emitting modules 40 to the main body 10 in a state in which the light emitting modules 40 are arranged in two rows on the left and three rows up and down through the left and right pivoting arms 55, the connecting rod 57, and the detachment hole 58. It can be used in the form of a flashlight.

And as the detachable port 58 can rotate left and right and up and down by the left and right pivoting arms 55 and the hinge rod 56, as shown in FIGS. 7 and 8, the light distribution angle of the light emitting module 40 can be adjusted left and right and up and down. Since it can be easily adjusted with , it not only ensures convenient work by illuminating the entire workplace while working, but also ensures quick evacuation by brightly illuminating the evacuation route in case of an emergency.

On the other hand, as shown in FIGS. 5 and 6, the detachable port 58 is an up and down pivoting arm 581 rotatably connected to the hinge rod 56, and an accommodation tube 582 fixed to the end of the up and down pivoting arm 581. ), a pair of sliding rods 583, one end of which is slidably accommodated inside one end and the other end of the receiving pipe 582, and a wedge-shaped engaging end 584 formed at the other end of the sliding rod 583 And, it may be composed of an elastic member 585 that is inserted inside both ends of the accommodation tube 582 and supports the engaging end 584 to be resilient to the outside of both ends of the accommodation tube 582.

Further, on both sides of the rear surface of the light emitting module 40, locking grooves 48 may be formed in which the locking end 584 is locked and fixed in a state in which the elastic member 585 is elasticd to the outside of both ends of the accommodation pipe 582.

Therefore, when the user presses the locking end 584 in a state where the locking end 584 is locked to the locking groove 48, the light emitting module 40 releases the locking end 584 from the locking groove 48. It can be easily separated from the detachable port 58.

Here, the light emitting module 40 is separated from the detachable port 58 and the main body 10 is separated from the holder body 51 to obtain the main body 10 as shown in FIG. 9 without using the holder body 51 and the handle 60. and the light emitting module 40 can also be used in a state connected only by the first cable 45.
