Description

Technical Field

[0001] This utility model belongs to the field of lighting device technology, and relates to a lighting device for civil defense engineering. Background Technology

[0002] Civil defense engineering refers to underground protective structures built separately to ensure the shelter of personnel and materials, command and control of civil air defense, and medical rescue during wartime. Because civil defense engineering is buried deep underground and lacks natural light, it must rely on lighting devices to meet the basic visual needs of personnel staying, working, and moving inside. Therefore, lighting devices play an important role in civil defense engineering.

[0003] A Chinese patent CN215570168U discloses an emergency lighting device for civil defense projects. The device includes a rotating mechanism on the upper surface of a power supply box. The rotating mechanism comprises a sliding sleeve, the lower surface of which is fixedly connected to the power supply box. Four positioning holes are evenly distributed on the arc surface of the sliding sleeve. A fixing rod is movably connected to the inner wall of the sliding sleeve. A slot is formed on the arc surface of the fixing rod. A spring is fixedly connected to the inner wall of the slot. A locking block is fixedly connected to the end of the spring away from the slot. The surface of the locking block is slidably connected to the slot. The size of the locking block matches the size of the positioning holes. A bracket is fixedly connected to the arc surface of the fixing rod. The surface of the bracket is fixedly connected to the lighting lamp. A limiting post is fixedly connected to the inner wall of the slot. The arc surface of the limiting post is slidably connected to the spring.

[0004] This emergency lighting device adjusts the angle of the light by rotating a fixed rod, which rotates horizontally. Since the lights are often installed at a high position, the horizontal beams tend to illuminate at a high height, requiring readjustment to reach the ground, making it inconvenient to use.

[0005] To address the aforementioned problems, this utility model proposes a lighting device for civil defense engineering. Utility Model Content

One end of each of the snap-fit ​​plates is rotatably sleeved on the fixed shaft, and the snap-fit ​​plates are arranged in a circumferential array about the fixed cylinder.

[0012] Each fixed shaft is fitted with a torsion spring at its bottom end. One end of the torsion spring is fixedly connected to the outer surface of the fixed shaft, and the other end of the torsion spring is fixedly connected to the clamping plate.

[0013] Each of the card plates is fixedly connected to a card block at the end away from the fixed axis. The horizontal cross-section of the card block is triangular. Both the card block and the card plate are movably disposed outside the connecting cylinder.

[0014] The outer surface of the connecting cylinder is provided with several sets of positioning elements from top to bottom. Each set of positioning elements consists of several slots. The slots in each set are evenly opened on the outer surface of the connecting cylinder. The number of slots in each set is equal to the number of card plates and corresponds one-to-one. The card block at the end of the card plate is movably engaged in the slot.

[0015] Furthermore, a connecting shaft is coaxially fixedly connected to the bottom surface of the turntable. The connecting shaft rotatably passes through the top surface of the rotating cylinder.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a lighting device for civil defense engineering, including a base 19, and a rotating cylinder 5 is lifted and lowered above the base 19.

[0030] A fixed cylinder 1 is fixedly connected to the center of the top surface of the base 19. A connecting cylinder 3 is coaxially fixedly connected to the bottom of the rotating cylinder 5, and the bottom end of the connecting cylinder 3 is coaxially movably disposed inside the fixed cylinder 1. The connecting cylinder 3 can slide up and down and rotate inside the fixed cylinder 1. A snap-fit ​​component is provided inside the fixed cylinder 1 to fix the connecting cylinder 3.

[0031] The snap-fit ​​component includes several arc-shaped snap-fit ​​plates 2. Several fixed shafts 22 are uniformly fixedly connected inside the fixed cylinder 1, and the fixed shafts 22 are arranged vertically. The number of snap-fit ​​plates 2 is equal to the number of fixed shafts 22. One end of each snap-fit ​​plate 2 is rotatably sleeved on the fixed shaft 22, and the snap-fit ​​plates 2 are arranged in a circumferential array about the fixed cylinder 1.

[0032] Each fixed shaft 22 has a torsion spring fitted at its bottom end. One end of the torsion spring is fixedly connected to the outer surface of the fixed shaft 22, and the other end of the torsion spring is fixedly connected to the clamping plate 2. The torsion spring drives the clamping plate 2 to rotate.

[0033] Each clamping plate 2 has a clamping block 18 fixedly connected to the end away from the fixed shaft 22. The horizontal cross-section of the clamping block 18 is triangular. Both the clamping block 18 and the clamping plate 2 are movably disposed outside the connecting cylinder 3. In the initial state, the torsion spring drives the clamping plate 2 to rotate, causing the clamping block 18 to abut against the outer surface of the connecting cylinder 3.

[0034] The outer surface of the connecting cylinder 3 is provided with several sets of positioning elements at intervals from top to bottom. Each set of positioning elements consists of several slots 4, which are evenly distributed on the outer surface of the connecting cylinder 3. The number of slots 4 in each set is equal to the number of locking plates 2 and corresponds one-to-one. The locking block 18 at the end of the locking plate 2 is movably engaged in the slot 4. By locking the end of the locking block 18 in the slot 4, the connecting cylinder 3 cannot move up and down, thus positioning the connecting cylinder 3 within the fixed cylinder 1.

[0035] A turntable 9 is axially mounted on the top of the rotating drum 5. Axial refers to the direction of the rotation center axis of the turntable 9, that is, the direction common to the center axis of the turntable 9, and the turntable 9 rotates in the horizontal direction.

[0036] A connecting shaft is coaxially fixed to the bottom surface of the turntable 9, and the connecting shaft rotates through the top surface of the rotating cylinder 5. A turntable 8 is coaxially fixed to the bottom end of the connecting shaft, and the top surface of the turntable 8 is rotatably positioned inside the rotating cylinder 5. A toothed ring 23 is coaxially fixed to the bottom surface of the turntable 8. The turntable 9 is positioned on the top of the rotating cylinder 5 by the turntable 8.

[0037] A rotating rod 6 rotatably passes through the side of the rotating cylinder 5, and a third gear 7 is fixedly connected to one end of the rotating rod 6 that extends into the rotating cylinder 5. A bearing is provided at the connection between the rotating rod 6 and the rotating cylinder 5 to increase the stability of the rotating rod 6. The third gear 7 is located below the turntable 8 and meshes with the gear ring 23. Rotating the third gear 7 drives the gear ring 23 to rotate through meshing.

[0038] A mounting plate 15 is radially rotatable on the top of the turntable 9. The radial direction is perpendicular to the axial direction, meaning that the mounting plate 15 rotates in the vertical direction.

[0039] A second fixing plate 21 is fixedly connected to the top of the turntable 9. The bottom end of the mounting plate 15 is rotatably connected to the second fixing plate 21, allowing the mounting plate 15 to rotate on the second fixing plate 21.

[0040] A lighting lamp 17 is fixedly installed on one side of the mounting plate 15. A threaded sleeve 16 is rotatably provided on the other side of the mounting plate 15.

[0041] Two third fixing plates 24 are symmetrically fixed to the side of the mounting plate 15 away from the lighting lamp 17. A threaded sleeve 16 is located between the two third fixing plates 24. Connecting rods are fixedly connected to the outer surfaces of the threaded sleeve 16 on both third fixing plates 24, and the other ends of the two connecting rods are rotatably connected to the corresponding third fixing plates 24. This allows the threaded sleeve 16 to rotate between the two third fixing plates 24, while simultaneously enabling the threaded sleeve 16 to move the mounting plate 15 via the third fixing plates 24.

[0042] The top of the turntable 9 is rotatably equipped with a rotating shaft 10, and a rotating block 12 is rotatably mounted on the rotating shaft 10.

[0043] Two first fixed plates 20 are symmetrically fixed to the top of the turntable 9, and the rotating shaft 10 rotates through the two first fixed plates 20. The rotating block 12 and the first bevel gear 11 are both located between the two first fixed plates 20. A rotating wheel is fixedly connected to one end of the rotating shaft 10, allowing the operator to rotate the rotating shaft 10 via the rotating wheel.

[0044] A lead screw 14 is rotatably connected to one side of the rotating block 12, and a threaded sleeve 16 is threaded onto the lead screw 14. When the lead screw 14 rotates, it drives the threaded sleeve 16 to move along the lead screw 14.

[0045] A second bevel gear 13 is fixedly sleeved on one end of the lead screw 14. A first bevel gear 11 is fixedly sleeved on the rotating shaft 10, and the first bevel gear 11 meshes with the second bevel gear 13. When the rotating shaft 10 rotates, the first bevel gear 11 drives the second bevel gear 13 to rotate, thereby causing the lead screw 14 to rotate.

[0046] Working principle:

[0047] When in use, use bolts to fix the base 19 in the civil defense building.

[0048] When the height of the lighting lamp 17 needs to be adjusted, rotate the connecting cylinder 3 clockwise. When the slot 4 rotates, it will push the locking block 18, causing the locking plate 2 to rotate. The end of the locking plate 2 rotates on the fixed shaft 22, driving the torsion spring to twist.

[0049] When the slot 4 rotates away from the locking block 18, the torsion spring drives the locking block 18 to abut against the outer surface of the connecting cylinder 3. At this time, the locking block 18 no longer restricts the connecting cylinder 3 and can move the connecting cylinder 3 up or down, so that the bottom end of the connecting cylinder 3 slides inside the fixed cylinder 1.

[0050] After moving the connecting cylinder 3 to a suitable height, move it slightly until the locking plate 2 aligns with one of the locking slots 4. Rotate the connecting cylinder 3 counterclockwise, causing the locking slot 4 to rotate toward the corresponding locking block 18. The torsion spring will drive the locking block 18 to move into the locking slot 4. Continue until the locking block 18 is abutted in the locking slot 4, thus fixing the connecting cylinder 3 in place.

[0051] When the angle of the lighting lamp 17 needs to be adjusted horizontally, rotate the lever 6, which drives the third gear 7 to rotate. The third gear 7 drives the gear ring 23 to rotate, causing the turntable 8 to rotate, which in turn drives the turntable 9 to rotate. This causes the mounting plate 15 and the lighting lamp 17 to rotate.

[0052] When the angle of the lighting lamp 17 needs to be adjusted vertically, rotate the shaft 10, which drives the first bevel gear 11 to rotate. The first bevel gear 11 drives the second bevel gear 13 to rotate, causing the lead screw 14 to rotate.

[0053] The lead screw 14 drives the threaded sleeve 16 to move along the lead screw 14. As the threaded sleeve 16 moves, it rotates between the two third fixed plates 24. Simultaneously, the threaded sleeve 16 drives the third fixed plates 24 to move, and the third fixed plates 24 drive the mounting plate 15 to move. At the same time, the lead screw 14 drives the rotating block 12 to rotate, causing the rotating block 12 to rotate on the rotating shaft 10. This causes the mounting plate 15 to rotate on the second fixed plate 21, thereby driving the lighting lamp 17 to rotate.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
