Description

SMOKE DETECTOR TEST DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for testing a smoke detector and, more particularly, to a smoke detector test device that enables it to operate wirelessly.

Smoke Detector is a type of fire detector that detects smoke when a fire occurs inside a building and can detect it sooner before the spread of the fire and output a warning signal. It is installed in most buildings for safety reasons .

Since the smoke detector installed as described above operates when a fire occurs, it is generally and preferably not to be operated for a long period of time. However, the smoke detector which has not been operated for a long time has a low sensitivity Or a failure of the apparatus may occur, it is necessary to test the smoke detector at regular time intervals for maintenance so that the smoke detector can perform minimum smoke detection and normal operation at all times for fire detection It is essential.

In order to test the smoke detector, it is necessary to exclude smoke or fire inside the building. Therefore, the test of the smoke detector generally requires a smoke that emits an aerosol containing a component that can be detected by the smoke detector Use a detector test spray. By spraying a small amount of the aerosol to the periphery of the smoke detector using the spray, it is possible to determine whether the smoke detector is malfunctioning by testing whether or not the smoke detector can sense the smoke.

However, since the sprayer is required to spray an aerosol directly around the smoke detector, the smoke detector is attached to the ceiling portion of the building, so that the inspector can directly test the smoke detector using the sprayer Not only does it cause discomfort, but it also creates the risk of safety accidents.

Therefore, in order to test the smoke detector installed on the ceiling, the inspector generally uses a smoke detection test apparatus in which a shaft having a predetermined length or longer is coupled to the spray. The smoke detection test apparatus may further include a mechanical or electrical device attached to the shaft to mount the spray on the end of the shaft rod and allow the inspector to operate the sprayer with the shaft raised, The user operates the sprayer indirectly through a switch or the like provided on the shaft without operating the sprayer to test the smoke detector.

As a problem of the above-described smoke detection test apparatus, the volume and weight become large due to the devices additionally installed in the shaft rod, which inconveniences the inspector. Further, in the case of a test apparatus in which an electric device is provided on the shaft to operate the spray, it is common that the inspector is connected by a wire between a switch for operating the spray and a valve for operating the spray, And because of the increase in weight, it is practically impossible to work alone, and at least two people must be working in order to be able to detect normally and cause frequent failures.

As a prior art related to the above conventional smoke detection test apparatuses, there are a flammable tester disclosed in Japanese Laid-Open Patent Application No. 2013-088963, a smoke detector tester disclosed in Japanese Laid-Open Patent Publication No. 1997-305874, Japanese Patent No. 5131626 , An operation tester for smoke detector disclosed in Japanese Patent No. 3586802, and the like.

Hereinafter, a structure and a method for coupling and coupling the coupling 320 to the gas spray 300 will be described with reference to FIGS. 5 and 6. FIG.

The smoke sensing test apparatus 1000 of the present invention uses the coupling 320 to connect the gas spray 300, which is an off-the-shelf product, to the spray coupling 310. This is because the standard of the gas spray 300 is slightly different according to the manufacturer and the product. Since it is necessary to prevent the gas G in the gas spray 300 from unnecessarily leaking to the outside, It is necessary to minimize the occurrence of a gap between the spray 300 and the engagement of the spray engagement portion 310. [ As described above, since the size of the gas spray 300 may be slightly different, the inlet specification of the gas spray 300 may be corrected through the coupling 320, So that they can be accurately combined.

The coupling 320 is formed in a circular ring shape with one side slightly opened to open, and the outer side is formed with a thread as shown in FIG. So that it can be engaged with the threads formed in the spray coupling part 310 so as to be screwed.

It is preferable to form a protruding surface by forming a locking protrusion 324 on the inner surface of the coupling 320 so that the locking protrusion 324 is formed at the inlet of the gas spray 300 So as to engage the spray jaws 301 and the spray guns 302 so that the coupling 320 can stably engage the inlet of the gas spray 320.

As described above, the coupling 320 is cut open at one side, and a screw groove 321 and a lead-in groove 322 are formed at the open end and the other end, respectively.

The threaded groove 321 and the lead-in groove 322 are formed on the coupling 320 such that a hollow is formed on the cut-away end portion of the outer surface of the coupling 320, The fastening screw 323 passes through the groove 321 and the lead-in groove 322.

More specifically, the fastening screw 323 is a conventional conventional screw in which a thread is formed. The screw groove 321 and the lead-in groove 322 are formed in accordance with the size of the fastening screw 323 do. The coupling screw 323 is inserted into the insertion groove 322 at the other end of the coupling 320 and is inserted into the screw groove 321 at one end of the coupling 320 through the hollow of the cross section. Since the screw groove 321 is internally threaded to fit with the fastening screw 323, the user tightens the fastening screw 323 into the screw groove 321, 320 can be adjusted. This can be referred to FIG. 6A.

The coupling springs 300 are coupled to the inlet spray jaws 301 and the spray guns 302 of the gas sprayer 300, The coupling 320 is in a state in which the inner diameter of the coupling 320 is not narrowed by the tightening screw 323 so that the coupling 320 can be moved in the direction of the gas spray 300 to the inlet spray jaws 301 of the apparatus.

In the state where the coupling 320 is extended to the spray jaw 301 as described above, the user tightens the coupling screw 323 on the coupling 320 in the above-described manner, So that the coupling 320 can be tightly coupled to the spray jaw 301 by reducing the inner diameter of the coupling 320.

6B, the engagement protrusion 324 is interposed between the spray jaws 301 and the spray guns 302, so that the coupling 320 is shaken to the gas spray 300 So that it can be fixedly coupled.

7, when the coupling 320 is coupled to the gas spray 300, the outer surface of the coupling 320 is inserted into the inner surface thread of the spray coupling 310, So that the gas spray 300 can be securely fastened to the spray coupling part 310 without shaking.
