Description

Technical Field

[0001] The utility model relates to the technical field of lighting accessories, in particular to a protective cover structure of an explosion-proof alarm lamp. Background Art

[0003] Although today's technology has many advantages, the disadvantage of today's technology is that the protective cover of the explosion-proof alarm light is mostly connected to the base with multiple bolts. However, when the alarm light is damaged due to changes in the working environment, it is necessary to use a special wrench to remove all the bolts. This not only increases the labor intensity of maintenance personnel, but also reduces the maintenance efficiency. At the same time, the protective covers of some explosion-proof alarm lights need to be used outdoors at high altitudes. When the alarm light is working, the internal components will release heat. Today's technology uses a motor and a fan for cooling, which wastes energy, and the motor is prone to failure, which increases the failure rate of the alarm light. Utility Model Content

[0025] like Figure 1-5 As shown, a slide groove 16 is provided on the outer surface of the protective cover 3, and a plurality of sliders 17 are movably embedded in the inner surface of the slide groove 16, so as to maintain the temperature inside the heat dissipation cover 19, and no motor is required, thus saving energy and reducing the failure rate.

[0026] like Figure 1-5 As shown, the outer surfaces of the plurality of limit rods 12 are fixedly connected with blocks 13, and the bottom inner surfaces of the plurality of slots 8 are fixedly connected with dampers 14, which can provide power for the reverse movement of the positioning rod 4, so that the positioning rod 4 moves in the reverse direction.

[0027] like Figure 1-5 As shown, a plurality of positioning rods 4 are fixedly connected to the bottom of the protective cover 3, and a plurality of circular plates 11 are movably embedded in the inner surfaces of a plurality of slots 9. The slots 9 can limit the moving trajectory of the circular plates 11, thereby preventing the circular plates 11 from derailing and affecting the use of the equipment.

[0032] Working principle: This device is a protective cover structure of an explosion-proof alarm lamp. When the lamp body 2 needs to be repaired, the protective cover 3 is manually pressed to make the protective cover 3 drive multiple positioning rods 4 to move downward on the inner wall of the slot 8, and the multiple positioning rods 4 drive multiple limit plates 5 and hemispherical blocks 6 to move downward. The multiple limit plates 5 will squeeze the multiple clamping sleeves 7, so that the multiple clamping blocks 13 will move in a straight line along the lower side slope of the multiple clamping sleeves 7. The multiple clamping blocks 13 squeeze the multiple circular plates 11 through the multiple limit rods 12, so that the multiple circular plates 11 squeeze the springs 10 inside the multiple slots 9, so that the multiple springs 10 obtain elastic potential energy. As the multiple positioning rods 4 move downward, The multiple hemispherical blocks 6 squeeze the circular plate 2 15, and the multiple circular plates 2 15 squeeze the multiple dampers 14, so that the multiple dampers 14 obtain elastic potential energy. At this time, the multiple card blocks 13 move to the side of the multiple card sleeves 7 close to the top, and the multiple springs 10 keep releasing the elastic potential energy, so that the multiple card blocks 13 keep moving along the surface of the multiple card sleeves 7, and finally the multiple card blocks 13 are stuck on the upper surface of the multiple card sleeves 7, and then the pressing of the protective sleeve 3 is stopped. At this time, the multiple dampers 14 release the elastic potential energy, push the multiple circular plates 2 15 to move upward, and the multiple circular plates 2 15 push the multiple hemispherical blocks 6 to move upward, and the multiple hemispherical blocks 6 drive the multiple positioning rods 4 to move upward. The rod 4 moves upward, and the multiple clamping blocks 13 make the multiple clamping sleeves 7 and the hemispherical blocks 6 fit together, and the multiple hemispherical blocks 6 and the clamping sleeves 7 have the same diameter, resulting in the multiple clamping blocks 13 moving along the inclined surface of the upper surface of the multiple clamping sleeves 7, and then directly moving to the lower surface of the hemispherical block 6. At this time, the protective cover 3 can be separated from the base 1, which is convenient for the maintenance of the inner wall lamp body 2, avoiding the removal of multiple bolts, improving the maintenance efficiency, shortening the failure cycle, and the alarm light is installed outdoors at a high altitude, so the wind will exert a force on the multiple fan blades 20 to rotate the multiple fan blades 20, and the multiple fan blades 20 drive the heat dissipation cover 19 to rotate, and the heat dissipation cover 1 9 drives the plurality of connecting rods 18 and two connecting rods 21 to rotate, the plurality of connecting rods 18 drive the plurality of sliders 17 to move on the inner surface of the slide groove 16, the two connecting rods 21 drive the plurality of fan blades 23 to rotate through the rotating shaft 22, the plurality of fan blades 23 apply kinetic energy to the air inside the heat dissipation sleeve 19, so that the air inside the heat dissipation sleeve 19 is discharged from the exhaust holes of the heat dissipation sleeve 19, resulting in the formation of a slightly low-pressure area inside the heat dissipation sleeve 19, so that when the lamp body 2 is working, the released heat energy naturally diffuses to the low-pressure area, and is finally discharged from the air holes of the heat dissipation sleeve 19, thereby maintaining the temperature inside the heat dissipation sleeve 19, and does not require a motor, saving energy and reducing the failure rate.
