Description

Technical Field

[0001] This invention relates to the field of fire-fighting lighting equipment technology, specifically a portable energy-saving lighting device for fire protection. Background Technology

[0002] Firefighting is a specialized field that studies fire prevention, firefighting, and disaster management. Its core objective is to reduce the probability of fires and effectively control fires when they occur, protecting people's lives and property. This field involves multiple aspects, including developing and enforcing fire safety regulations to ensure that buildings, public places, and industrial facilities meet fire safety standards. Fire departments are responsible for routine fire inspections, identifying fire hazards, and regularly maintaining fire equipment to ensure it is in good working order. Firefighters need to receive professional training, mastering firefighting techniques, rescue skills, and emergency response capabilities to enable rapid response and effective rescue at fire scenes. Furthermore, firefighting emphasizes public education, raising public awareness of fire prevention through publicity and training, enabling people to understand the dangers of fire and preventative measures, and master basic escape and self-rescue methods. Firefighting lighting is crucial in firefighting, rescue, and emergency evacuation scenarios, providing necessary illumination for firefighters to ensure the safety and efficiency of their operations.

[0003] Traditional fire-fighting lighting devices have limitations in practical use. First, their functional design is relatively simple, usually only supporting handheld operation or simple fixed placement, lacking multi-functional integration to adapt to the complex environment of a fire scene. In actual application, firefighters need to work in diverse scenarios such as narrow passages, underground spaces, and high-rise buildings. Traditional lighting devices cannot achieve flexible adjustment or hanging functions, resulting in insufficient lighting coverage when working in confined spaces and difficulty in reliable hanging when working at heights, which seriously restricts rescue efficiency and operational safety. Second, the portability of existing devices is significantly insufficient. The storage mechanism of some products is not perfect, making it inconvenient to carry during emergency response, resulting in low deployment efficiency, and even being unusable in specific work areas due to size limitations. This not only reduces the practical value of the equipment, but also affects the timeliness and adaptability of the overall rescue operation. Summary of the Invention

The guide block 602 has an inner rod 603 fixedly connected to its upper surface. The suspension device 7 includes a suspension housing 701, with a hanging ring 702 fixedly connected to its upper surface. A central rotating column 703 is rotatably connected to the middle of the inner cavity of the suspension housing 701. A coil spring 705, a rope drum 706, and a first gear 707 are fixedly connected to the outer surface of the central rotating column 703. A suspension rope 709 is provided on the outer surface of the rope drum 706. A limit mechanism 708 is provided inside the suspension housing 701. The locking mechanism 9 includes a guide groove 901 and two rotating rods 902. A push plate 903 is slidably provided in the guide groove inside the guide groove 901. A double-sided rack 904 and a third spring 905 are fixedly connected to both sides of the push plate 903, respectively. A second gear 906 and a bending rod 907 are fixedly connected to the outer surfaces of the two rotating rods 902.

[0032] The outer surface of the connecting base 501 is fitted inside the bottom storage groove 3. Multiple grooves 503 are formed on the outer surface of the connecting base 501. The end of the first spring 504 away from the support leg 502 is fixedly connected to the inside of the groove 503. The support leg 502, the groove 503 and the first spring 504 are arranged in a ring around the central axis of the connecting base 501. The bent part at the bottom of the support leg 502 is provided with a rivet hole 505. The groove 503 provides installation space for the first spring 504. The ring array of support leg 502, groove 503 and first spring 504 together ensures the uniformity and stability of the support. The first spring 504 provides driving force for the automatic unfolding of the support leg 502. The rivet hole 505 can be used to drive rivets into the ground to further enhance the fixing effect of the support device 5 on soft ground.

[0033] The lower surface of the suspension housing 701 is fixedly connected to the top of the inner rod 603. A fixing pin 704 is fixedly connected to the bottom of the inner cavity of the suspension housing 701. The end of the coil spring 705 away from the central rotating column 703 is connected to the fixing pin 704. A buckle 710 is fixedly connected to the end of the suspension rope 709 away from the central rotating column 703. A locking ring 711 is fixedly connected to the outer surface of the suspension housing 701. The coil spring 705 provides a restoring force to automatically rewind the suspension rope 709. The buckle 710 and the locking ring 711 cooperate to lock the end of the pulled-out suspension rope 709, thereby suspending the device at a high place.

[0034] The limiting mechanism 708 includes a support base 7081, the outer surface of which is fixedly connected to the top of the inner cavity of the suspension housing 701. A movable rod 7082 is sleeved inside the support base 7081. One end of the movable rod 7082 is fixedly connected to a limiting block 7083. The outer surface of the limiting block 7083 is adapted to the tooth groove of the first gear 707. The end of the movable rod 7082 away from the limiting block 7083 is rotatably connected to a pull column 7084. The outer surface of the pull column 7084 is fixedly connected to a limiting plate 7086. The limiting block 7083 locks the rope drum 706 by meshing with the tooth groove of the first gear 707, preventing the suspension rope 709 from being pulled out at will.

[0035] Limiting plates 7086 are symmetrically arranged on both sides of the pull column 7084. A through hole 712 is provided on the outer surface of the suspension housing 701. The outer surface of the pull column 7084 passes through the middle of the through hole 712. The limiting plates 7086 are adapted to the two wings of the through hole 712. A second spring 7085 is sleeved on the outside of the movable rod 7082. One end of the second spring 7085 is fixedly connected to the outer surface of the limiting block 7083. The end of the second spring 7085 away from the limiting block 7083 is fixedly connected to the support base 7081. The limiting plates 7086 cooperate with the specially shaped through hole 712. After the pull column 7084 is pulled out and rotated, it can be locked on the outer wall of the suspension housing 701, thereby keeping the limiting mechanism 708 in the unlocked state, which facilitates free adjustment of the length of the suspension rope 709. The second spring 7085 provides the elastic force that makes the limiting block 7083 press the first gear 707 under normal conditions, ensuring automatic locking.

[0036] The outer surface of the outer rod 601 is threaded into the inside of the threaded cavity 4. The bottom end of the outer rod 601 is fixedly connected to the upper surface of the connecting base 501. The two side protrusions of the guide block 602 are slidably disposed in the longitudinal guide groove of the inner wall of the outer rod 601. The outer surface of the guide block 602 is provided with a first insertion hole 604, which is symmetrically disposed on both sides of the guide block 602. The upper part of the outer surface of the inner rod 603 is provided with a second insertion hole 605, which is symmetrically disposed on the inner rod. On both sides of the inner rod 603, a third insertion hole 606 is provided on the upper part of the outer surface of the outer rod 601. The third insertion hole 606 is symmetrically arranged on both sides of the outer rod 601. The guide block 602 cooperates with the longitudinal guide groove to prevent the inner rod 603 from rotating relative to the outer rod 601 and ensure that it can only slide axially. The first insertion hole 604, the second insertion hole 605 and the third insertion hole 606 are used to cooperate with the insertion rod 908 of the locking mechanism 9 to realize the reliable fixation of the inner rod 603 in the retracted state and the extended state.

[0037] The lower surface of the guide groove 901 is fixedly connected to the upper surface of the top fixed seat 8. The bottom ends of the two rotating rods 902 are rotatably connected to the upper surface of the top fixed seat 8. The end of the bent rod 907 away from the rotating rod 902 is fixedly connected to the insertion rod 908. The interiors of the first insertion hole 604, the second insertion hole 605, and the third insertion hole 606 are all adapted to the outer surface of the insertion rod 908. The guide groove 901 provides movement for the push plate 903 and the double-sided rack 904. The bent rod 907 converts the rotational motion of the rotating rod 902 into the arc motion of the insertion rod 908. The insertion rod 908 achieves mechanical locking of the telescopic rod device 6 in the telescopic state by inserting or withdrawing from different insertion holes.

[0038] Two rotating rods 902 are symmetrically arranged on both sides of the guide groove 901, two bent rods 907 are symmetrically arranged on both sides of the telescopic rod device 6, two insert rods 908 are symmetrically arranged between the two bent rods 907, and two second gears 906 are symmetrically arranged on both sides of the double-sided rack 904. Both second gears 906 mesh with the double-sided rack 904. The symmetrical arrangement of the rotating rods 902, bent rods 907 and insert rods 908 ensures that locking force is applied to the telescopic rod device 6 from both sides at the same time, preventing jamming or deflection caused by force on one side.

[0039] The push plate 903 is located at the end of the double-sided rack 904 away from the telescopic rod device 6. The end of the third spring 905 away from the push plate 903 is fixedly connected to the guide groove of the guide groove 901 away from the telescopic rod device 6. The third spring 905 provides elastic force to reset the entire locking mechanism 9, that is, to drive the double-sided rack 904 to reset and keep the insertion rod 908 in the inserted and locked state, which improves the safety and convenience of use.

[0040] The working principle of the above embodiments:

[0041] The telescopic rod device 6, in conjunction with the locking mechanism 9, allows for the fixing and releasing of the telescopic state, facilitating lighting in confined spaces. In use, first operate the locking mechanism 9 to push the push plate 903, causing the double-sided rack 904 to move, stretching the third spring 905. The double-sided rack 904 drives the two second gears 906 to rotate, which in turn rotates the rotating rod 902 and the bending rod 907, causing the insertion rod 908 to exit from the second insertion hole 605 and the third insertion hole 606. Then, pull the inner rod body 603 upwards to extend it from the outer rod 601 until the guide block 602 moves to the top of the inner cavity of the outer rod 601. At this point, the first insertion hole 604 aligns with the third insertion hole 606. Release the push plate 903, and the third spring 905... Under the action of elasticity, the insertion rod 908 is inserted into the third insertion hole 606 and the first insertion hole 604, keeping the inner rod 603 in the extended state. At this time, by holding the inner rod 603, the lamp holder 1 and the lamp body 2 can be inserted into a narrow space for lighting. When storing, the locking mechanism 9 is operated again to make the insertion rod 908 leave the first insertion hole 604 and the third insertion hole 606, and the inner rod 603 is retracted into the outer rod 601 until the guide block 602 moves to the bottom of the inner cavity of the outer rod 601. At this time, the telescopic rod device 6 is in the maximum retracted state. Release the push plate 903 of the locking mechanism 9 to make the insertion rod 908 insert into the third insertion hole 606 and the second insertion hole 605, keeping the inner rod 603 in the retracted state, thus completing the retraction and storage of the telescopic rod device 6.

[0042] The support device 5 enables the lighting fixture to be placed on the ground. In use, first operate the telescopic rod device 6 to keep the inner rod 603 in the extended state, then hold the inner rod 603 and rotate the entire telescopic rod device 6 to make the outer rod 601 rotate downward along the threaded cavity 4, causing the support device 5 to extend from the bottom storage slot 3. At this time, the first spring 504, which was originally compressed, returns to its original position and extends, pushing the support leg 502 to unfold and form a stable support. When storing, rotate the inner rod 603 in the opposite direction to drive the support device 5 back into the bottom storage slot 3, the support leg 502 retracts, the first spring 504 is compressed, and compact storage is achieved.

[0043] The suspension device 7 provides multiple usage methods, including hand-carrying, hanging, and rope hanging. The hanging ring 702 can be used to carry the entire lamp by hand or to hang it directly on an external object. When using the suspension rope 709, first pull the pull column 7084 outward, causing the movable rod 7082 and the limiting block 7083 to disengage from the tooth groove of the first gear 707. At the same time, the two limiting plates 7086 pass through the through hole 712 and move out to the outside of the suspension housing 701. Then rotate the pull column 7084, causing the two limiting plates 7086 to shift off the through hole 712 and abut against the outer wall of the suspension housing 701, keeping the limiting block 7083 in the state of disengaging from the first gear 707. At this time, the second spring 7085 is compressed. Then pull the lock 710 at one end of the suspension rope 709, and the central rotating column 7089 will rotate. 03 rotates accordingly, driving the first gear 707 and the rope drum 706 to rotate. The coil spring 705 deforms and stores energy until the suspension rope 709 is pulled out to a suitable length. Then, the pull column 7084 is rotated to align the limiting plate 7086 with the through hole 712. After the pull column 7084 is released, under the elastic force of the second spring 7085, the limiting block 7083 is inserted into the corresponding tooth groove of the first gear 707, keeping the suspension rope 709 at the current length for easy hanging of the lighting lamp. When hanging, the lock 710 is locked on the locking ring 711. After hanging is finished, the pull column 7084 is pulled outward again to make the limiting block 7083 leave the first gear 707. Under the elastic restoring force of the coil spring 705, the suspension rope 709 automatically rewinds back onto the rope drum 706.
