Detailed implementation manners

[0040] Referring to an embodiment herein means that the specific features, structures, or characteristics described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears at various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0041] Embodiment 1: An LED lamp with adjustable light output range, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, it includes a storage box 1. A door 11 is rotatably connected to the left part of the front side of the storage box 1. A limiting member 12 is fixedly connected to the front side of the top of the storage box 1. The limiting member 12 is arranged in a fan shape that inclines inward. A servo motor 13 is installed on the right side of the top of the storage box 1. The output shaft of the servo motor 13 is connected to a rotating lead screw 14 through a coupling. A guide rod 15 is fixedly connected to the left side of the top of the storage box 1. A lifting frame 17 is threadedly connected to the rotating lead screw 14, and the lifting frame 17 is slidably connected to the guide rod 15. An LED lamp body 16 is rotatably connected to the lifting frame 17. A dimming component is provided on the LED lamp body 16. A smoke sensor 110 is installed on the lifting frame 17, and the smoke sensor 110 is electrically connected to the servo motor 13. A clamping component is provided on the lifting frame 17.

[0042] As Figure 3 , Figure 4 and Figure 5 shown in the figure, the dimming component includes a zoom sleeve 1601. The zoom sleeve 1601 is slidably connected to the LED lamp body 16. Symmetrically distributed return springs 112 are connected between the zoom sleeve 1601 and the LED lamp body 16. Both of the two return springs 112 are wound around the LED lamp body 16. A connecting block 18 is fixedly connected to the bottom of the zoom sleeve 1601, and the connecting block 18 slides on the limiting member 12.

[0043] As Figure 5 shown in the figure, the clamping component includes a plug rod 19. The plug rod 19 is slidably connected to the lifting frame 17. A return spring 111 is connected between the plug rod 19 and the lifting frame 17. The return spring 111 is wound around the plug rod 19. A cross-shaped chute is opened inside the rear side of the LED lamp body, and the plug rod 19 slides in the cross-shaped chute.

[0044] As Figure 6 , Figure 7 and Figure 8 shown in the figure, it further includes a rescue mechanism for allowing people to reduce the inhalation of toxic gases and particulate matter during a fire. The rescue mechanism is arranged in the storage box 1. The rescue mechanism includes a connecting rod 2. The connecting rod 2 is fixedly connected to the left side of the lifting frame 17. A threaded sleeve 23 is fixedly connected to the front side of the connecting rod 2. A screw rod 21 is fixedly connected to the left side of the door 11, and the screw rod 21 is threadedly connected to the threaded sleeve 23. A placement rack 24 is fixedly connected to the inner bottom wall of the storage box 1. At least eight compartments are provided in the placement rack 24, and rescue items such as towels, smoke masks, life ropes, etc. can be placed in the compartments. A sprinkler component is provided on the storage box 1.

[0045] As Figure 7 , Figure 8 and Figure 9As shown, the sprinkler assembly includes a first water outlet frame 22. The first water outlet frame 22 is fixedly connected to the top of the storage box 1. A water inlet pipe is provided at the top of the first water outlet frame 22. The bottom of the first water outlet frame 22 is fixedly connected to a second water outlet frame 25. The second water outlet frame 25 is connected to the left and right inner walls of the storage box 1. Uniformly distributed water outlet nozzles are provided on both the first water outlet frame 22 and the second water outlet frame 25.

[0046] First, install this device on the escape passage. Initially, the limiting member 12 abuts against the connecting block 18, and the return spring 112 is in a deformed state. Moreover, the water inlet pipe on the first water outlet frame 22 is connected to an external water pipe. Rescue items are placed on the placement rack 24. When a fire breaks out and the generated smoke is greater than the preset value of the smoke sensor 110, the smoke sensor 110 will control the servo motor 13 to rotate forward, and the first water outlet frame 22 and the second water outlet frame 25 will sprinkle water. The water sprayed by the first water outlet frame 22 can extinguish the surrounding fire points, and the water sprayed by the second water outlet frame 25 can wet the towels on the placement rack 24. The servo motor 13 will drive the rotating lead screw 14 to rotate forward, thereby driving the lifting frame 17 to move upward, and then driving the LED lamp body 16, the connecting block 18, and the connecting rod 2 to move upward. As the connecting block 18 continues to move upward until it separates from the limiting member 12, under the elastic action of the return spring 112, the zoom sleeve 1601 will slide forward. The forward-sliding zoom sleeve 1601 makes the light beam emitted by the LED lamp body 16 concentrated and has strong penetration, effectively focusing the light, and can enhance the guiding effect of the fire emergency lamp.

[0047] At the same time, the upward-moving connecting rod 2 will drive the threaded sleeve 23 to move upward, thereby driving the screw rod 21 to drive the door 11 to rotate and open. At this time, people can come to the side of the storage box 1 according to the guidance of the light beam emitted by the LED lamp body 16 and take the required rescue items from the opened storage box 1, such as wet towels, smoke masks, life ropes, etc. The wet towels can help people cover their mouths and noses and reduce the risk of inhaling toxic smoke. The smoke mask can provide a higher level of respiratory protection, and the life rope can be used for emergency escape or rescue when needed. After taking out the necessary rescue items, people can continue to move towards a safer location along the guidance of the light beam provided by the LED lamp body 16 until they completely leave the dangerous area.

[0048] When the fire is extinguished and the remaining smoke is less than the preset value of the smoke sensor 110, the smoke sensor 110 will control the servo motor 13 to drive the rotating lead screw 14 to reverse, and the first water outlet frame 22 and the second water outlet frame 25 will stop sprinkling water, thereby driving the lifting frame 17, the LED lamp body 16, the connecting block 18, and the connecting rod 2 to move downward. When the connecting block 18 moves downward to contact the limiting member 12, the top surface of the limiting member 12 will abut against the connecting block 18 to move the zoom sleeve 1601 backward to reset, and the return spring 112 will return to the deformed state. At the same time, the connecting rod 2 will drive the threaded sleeve 23 to move downward to contact the screw rod 21, thereby driving the door 11 to rotate and close through the screw rod 21.

[0049] When it is necessary to change the irradiation direction of the LED lamp body 16, the insertion rod 19 can be first pulled backward to withdraw it from the LED lamp body 16, and the return spring 111 will deform. Then, the LED lamp body 16 can be rotated 90 degrees to the left or 90 degrees to the right. After releasing the insertion rod 19, under the elastic action of the return spring 111, the insertion rod 19 will move forward to reset and insert into the LED lamp body 16 for positioning. To sum up, first, through the cooperation of the smoke sensor 110 and the servo motor 13, when a fire occurs, the LED lamp body 16 can generate a light beam with effective focusing and strong penetration, so that more clear guidance can be obtained even when the smoke concentration is high. Then, through the cooperation of the screw rod 21 and the threaded sleeve 23, the door 11 can be automatically opened to expose the rescue items inside the storage box 1, such as wet towels, smoke masks, life ropes, etc., thereby improving the success rate and safety of escape.

[0050] Embodiment 2: On the basis of Embodiment 1, as Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15As shown in the figure, it further includes a limiting mechanism for limiting the rescue items in the placement rack 24. The limiting mechanism is arranged in the storage box 1. The limiting mechanism includes a guiding rack 3. The lower part of the right inner wall of the storage box 1 is fixedly connected with the guiding rack 3. The return pull rod 31 is slidably connected in the guiding rack 3. The lower part of the right inner wall of the storage box 1 is fixedly connected with a connecting plate 32. A latch 33 is slidably connected to the connecting plate 32. A limiting spring 39 is connected between the latch 33 and the connecting plate 32. The rear side of the inner bottom wall of the storage box 1 is fixedly connected with a jig guiding plate 38. A jig rod 35 is slidably connected to the jig guiding plate 38. The jig rod 35 is located behind the placement rack 24. A uniformly distributed jig holder 36 is slidably connected in the jig rod 35. The uniformly distributed jig holders 36 all extend into the adjacent compartments. A linear spring 37 is connected between each of the uniformly distributed jig holders 36 and the jig rod 35. The lower right part of the rear side of the jig rod 35 is fixedly connected with an L-shaped guiding plate 34. An inclined slideway is opened in the L-shaped guiding plate 34. The return pull rod 31 slides in the inclined slideway. A jack is opened in the return pull rod 31. The return pull rod 31 is in extrusion fit with the latch 33.

[0051] Initially, the door 11 is in an open state. When it is necessary to place rescue items into the placement rack 24, the staff can manually push the return pull rod 31 backward. The return pull rod 31 will lift the L-shaped guiding plate 34 upward so that it drives the jig rod 35 to move upward. As the return pull rod 31 continues to move backward until it contacts the latch 33, the return pull rod 31 will push the latch 33 upward, and the limiting spring 39 will deform. When the latch 33 no longer abuts against the return pull rod 31, under the elastic action of the limiting spring 39, the latch 33 moves downward to reset and insert into the jack of the return pull rod 31 to limit the return pull rod 31. At this time, the return pull rod 31 will maintain the state of holding the L-shaped guiding plate 34, that is, the jig rod 35 and the jig holders 36 stay in an upward-moved state, so that each jig holder 36 contacts the inner side of the top plate of the compartment of the placement rack 24. At this time, the staff can place rescue items on each compartment of the placement rack 24.

[0052] After all the items are placed, first pull the bolt 33 upward to disengage it from the return pull rod 31, restricting the spring 39 from deforming again. Then pull the return pull rod 31 forward to its original position. The return pull rod 31 no longer supports the L-shaped guide plate 34. Release the bolt 33, and under the action of the restricting spring 39, the bolt 33 moves downward to reset. At the same time, under the action of the gravity of the fixture rod 35 and the L-shaped guide plate 34 itself, the fixture rod 35 drives the fixture frame 36 to move downward to reset. The downward-moving fixture frame 36 is blocked by the items on the partition layer, causing the linear spring 37 to deform slightly. Under the elastic force of the linear spring 37, the fixture frame 36 clamps the items on the partition layer. To sum up, through the cooperation of the return pull rod 31 and the bolt 33, it is convenient for the fixture frame 36 to limit the rescue items in the placement rack 24, which helps people quickly find the required items in an emergency, reduces the time wasted in searching for items, and improves the success rate and safety of escape.

[0053] As Figure 16 and Figure 17 shown, it also includes an auxiliary mechanism for locking and unlocking the door 11 when it is opened. The auxiliary mechanism is arranged on the storage box 1. The auxiliary mechanism includes connecting limit blocks 45. Two connecting limit blocks 45 are fixedly connected to the left side of the storage box 1. A clamping position pull rod 42 is slidably connected between the two connecting limit blocks 45. Connecting springs 44 are connected between the clamping position pull rod 42 and the two connecting limit blocks 45. A clamping position member 43 is fixedly connected to the screw rod 21. A clamping slot is opened on the clamping position member 43. The connecting rod 2 is in pressing cooperation with the clamping position pull rod 42. An unlocking component for releasing the limit of the bolt 33 on the return pull rod 31 is arranged in the storage box 1.

[0054] Initially, the connecting spring 44 is in a deformed state. When the screw rod 21 drives the door 11 to rotate and open, the screw rod 21 also drives the clamping position member 43 to rotate forward by 180 degrees. At this time, the clamping slot on the clamping position member 43 is aligned with the clamping position pull rod 42. Under the elastic action of the connecting spring 44, the clamping position pull rod 42 moves to the right and is clamped into the clamping position member 43, locking the screw rod 21, so that the door 11 can remain open during a fire. According to the previous steps, after the fire, when the connecting rod 2 drives the threaded sleeve 23 to move downward to contact the screw rod 21, the connecting rod 2 first presses the clamping position pull rod 42 to move it to the left, and the clamping position pull rod 42 withdraws from the clamping slot of the clamping position member 43.

[0055] When the screw 21 drives the door 11 to rotate and close, the card slot of the card member 43 also reverses 180 degrees to reset, and the connecting spring 44 returns to its deformed state. To sum up, through the cooperation of the connecting rod 2, the card member 43, and the card pulling rod 42, the door 11 can be locked in the normally open state during a fire and unlocked after the fire is over, preventing people from accidentally hitting the door 11 due to panic or blocked vision during an emergency evacuation, which may cause it to close accidentally. This will not only hinder subsequent personnel from accessing rescue items but also may cause panic and chaos, thus improving the success rate and safety of escape.

[0056] As Figure 18 and Figure 19 shown, the unlocking assembly includes a T-shaped guide plate 41. The T-shaped guide plate 41 is fixedly connected to the inner side of the lower right part of the rear wall of the storage box 1. The unlocking member 4 is slidably connected to the T-shaped guide plate 41. The unlocking member 4 is in extrusion fit with the bolt 33. The compression spring 46 is connected between the return pull rod 31 and the guide frame 3.

[0057] Initially, the bolt 33 is inserted into the return pull rod 31 to limit it, and the compression spring 46 is in a deformed state. After the rescue items in the placement rack 24 are placed, the door 11 can be closed. The door 11 will push the unlocking member 4 to move backward. The unlocking member 4 moving backward will squeeze the bolt 33 and push it upward, causing the limit spring 39 to be in a deformed state. The bolt 33 will withdraw from the return pull rod 31. Under the elastic action of the compression spring 46, the return pull rod 31 moves backward to reset. According to the previous steps, the return pull rod 31 no longer supports the L-shaped guide plate 34. At the same time, under the action of the gravity of the jig rod 35 and the L-shaped guide plate 34 itself, the jig frame 36 will clamp the items on the partition. When the door 11 is opened, the door 11 no longer presses against the unlocking member 4. At the same time, under the elastic action of the limit spring 39, the bolt 33 will move downward to reset, and the unlocking member 4 will move forward to reset. To sum up, through the cooperation of the unlocking member 4 and the compression spring 46, when the door 11 is closed, the bolt 33 automatically withdraws from the return pull rod 31 without manual operation. The rescue items will be fixed by the jig frame 36, improving the efficiency of item placement and retrieval and reducing delays or chaos caused by improper operation in an emergency.
