Description

Technical Field

[0001] This utility model relates to a lighting lamp with fire detection and alarm functions, belonging to the field of lighting technology. Background Technology

[0002] Lighting fixtures not only provide illumination, but can also create different atmospheres and visual effects through their design, color, and brightness.

[0003] For example, Chinese patent CN211315910U discloses a smart building lighting fixture, including an LED panel, a protective frame, a panel frame, a lamp holder, a heat dissipation fin, a transition plate, a smart tailstock, a mounting bracket, and fastening screws. The back of the LED panel is embedded in the lamp holder, and the protective frame is bonded to the front of the panel frame. This smart building lighting fixture optimizes the smart tailstock design. When manual activation is required in special circumstances, sliding the sliding key causes the top moving part on the mating part to move to the right, and the left side of the tilting part to move downward and contact the triggering part. At this time, the intermediate contact receives information and transmits it to the core board, thereby controlling the LED panel on the lighting fixture to be powered on and turn on the lighting mode. This efficiently assists in achieving manual touch-controlled activation and has a good user experience.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use. For example, when the device is not in use during the day, it will be exposed to the outside environment for a long time. In a strong sunlight environment, the ultraviolet radiation from the sunlight will cause the lampshade to age and discolor. The aged and discolored lampshade may absorb more light, reducing the amount of light transmitted to the outside, thus giving people the feeling that the light is not bright enough. At the same time, the device cannot detect or alarm for fires. In the event of a fire, the device cannot sound an alarm to remind people to pay attention to safety and take escape measures. This may cause people to lose precious escape time in a fire, increasing the risk of casualties. Summary of the Invention

[0037] The springs 18 are distributed at equal intervals. Example 1

[0038] This embodiment includes:

[0039] The lighting body 1 has a sliding groove 2 inside. A fixed plate 3 is symmetrically fixedly installed in the sliding groove 2.

When the two sliding plates 4 7 enter the two sliding plates 3 6 respectively, then the two sliding plates 3 6 enter the two sliding plates 2 5 respectively, then the two sliding plates 2 5 enter the two sliding plates 1 4 respectively, and then the two sliding plates 1 4 enter the two fixed plates 3 respectively, the lampshade on the lighting body 1 is finally fully exposed to the outside world. At this time, the lighting body 1 is turned on, and the light generated by the lighting body 1 will spread to the outside world. Through the above reverse operation, the lampshade on the lighting body 1 can also be protected to prevent the lampshade on the lighting body 1 from aging and discoloring due to ultraviolet radiation, and can also block dust from entering the lampshade of the lighting body 1 during the day.

[0046] In this embodiment, the driving component includes:

[0047] Two threaded rods 9 are rotatably installed in the sliding groove 2 and are located on the upper and lower sides of the sliding plate 7 respectively. One end of each threaded rod 9 passes through the four rectangular plates 8. Each threaded rod 9 has two sections of threads with opposite directions, and each threaded rod 9 is threadedly connected to the four rectangular plates 8 respectively.

[0048] Motor 13 is fixedly installed in sliding groove 2. The output shaft of motor 13 is fixedly installed with worm 14. Two worm wheels 15 are meshed on one side of worm 14. The two worm wheels 15 are located on one side of two threaded rods 9 respectively, and the two worm wheels 15 are fixedly connected to the two threaded rods 9 respectively. Worm 14 and two worm wheels 15 are rotatably connected to sliding groove 2.

[0049] In this process, the motor 13 is started, and when the motor 13 is powered on, it drives the worm gear 14 to rotate in the forward direction. The worm gear 14 drives the two worm wheels 15 that mesh with it to rotate. The two worm wheels 15 drive the two threaded rods 9 to rotate respectively. Under the action of the threads, the two threaded rods 9 drive the two sliding plates 4 and 7 to slide and move away from each other through the four rectangular plates 8 respectively. When the two sliding plates 4 and 7 respectively enter the two sliding plates 3 and 6 respectively, then the two sliding plates 3 and 6 respectively enter the two sliding plates 2 and 5 respectively, then the two sliding plates 2 and 5 respectively enter the two sliding plates 1 and 4 respectively, then the two sliding plates 1 and 4 respectively enter the two fixed plates 3, the lamp cover on the lighting body 1 is finally fully exposed to the outside world. At this time, the lighting body 1 is started, and the light generated by the lighting body 1 will spread to the outside world. Through the above reverse operation, the lamp cover on the lighting body 1 can also be protected to prevent the lamp cover on the lighting body 1 from aging and discoloring due to ultraviolet radiation, and can also block dust from entering the lamp cover of the lighting body 1 during the day.

A driving block 19 is fixedly installed on the rear side of the connecting plate 16. The rear side of the driving block 19 passes through the limiting groove 10 and extends to the outside. Several springs 18 fixed to the inner wall of the limiting groove 10 are fixedly installed on the rear side of the connecting plate 16. The driving block 19 is slidably connected to the limiting groove 10.

[0052] When installing the smoke alarm 11, first pull the drive block 19 to slide away from the fixed plate 3. The drive block 19 drives the connecting plate 16 to slide, and at the same time, several springs 18 are compressed and contracted. The connecting plate 16 pulls the two connecting rods 17 to rotate. The two connecting rods 17 pull the two limiting blocks 12 to slide away from each other. When the two limiting blocks 12 slide to the appropriate position, the smoke alarm 11 can be inserted into the limiting groove 10. Finally, the operator releases the drive block 19. Under the rebound force of several springs 18, the connecting plate 16 drives the smoke alarm 11 to slide closer to the fixed plate 3. The connecting plate 16 squeezes the two connecting rods 17 to rotate. The two connecting rods 17 squeeze the two limiting blocks 12 to slide and move closer to each other.

[0062] In this embodiment, the two sliding plates 4 7 are in close contact on their sides.

[0063] Among them, the two sliding plates 7 can prevent dust from entering the lampshade of the lamp body 1 during the day.

[0064] It is worth noting that the smoke alarm 11 involved in this utility model uses a smoke detector with product number RS-YG / YG2-N01 produced by Shandong Renke Measurement and Control Technology Co., Ltd. The smoke alarm 11 involved in this utility model is existing technology, which can be fully implemented by those skilled in the art, and there is no need to elaborate. The content protected by this utility model does not involve any improvement to the structure and working principle of the smoke alarm 11.

[0065] Working principle: When smoke from a fire enters the smoke detector 11, the smoke particles scatter the light emitted by the light source, causing some of the light to deviate from its original path. The intensity of the light scattered onto the photosensitive element is weakened. When the light intensity detected by the photosensitive element is lower than the preset threshold, the lighting body 1 will sound an alarm, which can remind people to pay attention to safety and take escape measures.

[0066] When installing the smoke alarm 11, firstly, the drive block 19 is slid away from the fixed plate 3 by pulling the arc-shaped groove. The drive block 19 drives the connecting plate 16 to slide, and at the same time, several springs 18 are compressed and contracted. The connecting plate 16 pulls the two connecting rods 17 to rotate. The two connecting rods 17 pull the two limiting blocks 12 to slide away from each other. When the two limiting blocks 12 slide to the appropriate position, the smoke alarm 11 can be inserted into the limiting groove 10. Finally, the operator releases the drive block 19. Under the rebound force of several springs 18, the connecting plate 16 drives the smoke alarm 11 to slide closer to the fixed plate 3. The connecting plate 16 squeezes the two connecting rods 17 to rotate. The two connecting rods 17 squeeze the two limiting blocks 12 to slide and move closer to each other. The two limiting blocks 12 will be inserted into the smoke alarm 11, which can fix the position of the smoke alarm 11 and complete the installation of the smoke alarm 11. The smoke alarm 11 can also be disassembled by the above reverse operation. The operation is simple and does not require tools.

[0067] When the sunlight is dim, the motor 13 is started. The motor 13 is powered on and drives the worm gear 14 to rotate in the forward direction. The worm gear 14 drives the two worm wheels 15 that mesh with it to rotate. The two worm wheels 15 drive the two threaded rods 9 to rotate respectively. Under the action of the threads, the two threaded rods 9 drive the two sliding plates 4 and 7 to slide and move away from each other through the four rectangular plates 8 respectively. When the two sliding plates 4 and 7 respectively enter the two sliding plates 3 and 6 respectively, then the two sliding plates 3 and 6 respectively enter the two sliding plates 2 and 5 respectively, then the two sliding plates 2 and 5 respectively enter the two sliding plates 1 and 4 respectively, then the two sliding plates 1 and 4 respectively enter the two fixed plates 3, the lamp cover on the lighting body 1 is finally fully exposed to the outside world. At this time, the lighting body 1 is started, and the light generated by the lighting body 1 will spread to the outside world. Through the above reverse operation, the lamp cover on the lighting body 1 can also be protected to prevent the lamp cover on the lighting body 1 from aging and discoloring due to ultraviolet radiation, and can also block dust from entering the lamp cover of the lighting body 1 during the day.
