The lighting that is enabled due to power failure of normal lighting is called emergency lighting.

[0003] An existing patent (publication number: CN 218468896 U) discloses an elevator emergency lighting device, including a rotating rod, a driving gear, a driven gear, a screw, a groove, and a slide rod. The rotating rods are symmetrically installed on the left and right sides of the lower end surface of the elevator roof, the driving gear is welded to the upper end surface of the rotating rod, the screw rod is installed above the driving gear, and the driven gear is welded to the surface of the screw rod. Grooves are symmetrically opened on the inside of the elevator roof, and slide rods are symmetrically installed on both sides of the groove. This design solves the problem that the original elevator emergency lighting device had a cumbersome disassembly process and was not conducive to subsequent maintenance. The new design has a reasonable structure, good lighting effect, and a simple disassembly process, which is conducive to subsequent replacement and maintenance.

[0004] Although the above-mentioned elevator emergency lighting device is easy to disassemble, the elevator may fall from a certain height when it fails, which can easily cause the emergency lighting to vibrate, resulting in damage to the emergency lighting and loss of lighting function.

[0012] Furthermore, four mounting rods are fixedly connected to the bottom surface of the fixing frame, a mounting ring is slidably sleeved on the outer circumference of the four mounting rods, and a nut is threadedly connected to the outer circumference of each mounting rod.

[0015] Through the above solution, the control rod is protected, the sliding and deviation of the control rod are avoided, and the stability of the control rod movement is increased.

[0016] Furthermore, the outer circumferential surface of the positioning rod is fixedly connected to two limit blocks, and the outer surface of each limit block is slidably connected to the fixing seat through a hollow groove opened inside the fixing seat.

[0017] Through the above solution, the positioning rod is restricted to prevent the positioning rod from rotating along with the control rod, so that the positioning rod is always moved laterally.

[0018] Furthermore, a hand wheel is fixedly sleeved on the outer circumference of the control rod, and the outer circumference of the hand wheel is provided with anti-slip grooves arranged at equal intervals.

[0032] See also Figure 2 The bottom surface of the top plate 1 is fixedly connected with a damper 7, the bottom surface of the damper 7 is fixedly connected to the upper surface of the base 3, the bottom surface of the top plate 1 is fixedly connected with a spring 8, the bottom end of the spring 8 is fixedly connected to the upper surface of the base 3, and the emergency light 5 is buffered and shock-absorbing by the damper 7 and the spring 8 to prevent the emergency light 5 from being easily damaged by vibration and losing its lighting function.

[0033] See also Figure 1 and Figure 2 The outer circumference of the base 3 is fixedly connected with four equidistantly arranged sliders 9, and the interior of the fixed frame 2 is provided with four equidistantly arranged slide grooves 10. The outer surface of the slider 9 is slidably connected to the fixed frame 2 through the slide groove 10, which restricts the base 3, prompting the base 3 to always perform longitudinal lifting and lowering, thereby increasing the stability of the base 3.

[0034] See also Figure 1 and Figure 2 Four mounting rods 11 are fixedly connected to the bottom surface of the fixed frame 2, and a mounting ring 12 is slidably sleeved on the outer circumference of the four mounting rods 11. A nut 13 is threadedly connected to the outer circumference of each mounting rod 11. The mounting ring 12 is positioned by the mounting rod 11 and the nut 13, and the slider 9 is restricted by the mounting ring 12 to prevent the slider 9 from easily slipping out of the slide groove 10, thereby increasing the stability of the base 3.

[0035] See also Figure 4The outer circumference of the control rod 15 is fixedly sleeved with a limit ring 17, and the outer circumference of the limit ring 17 is rotatably connected to the inner part of the fixed seat 14 to protect the control rod 15, prevent the control rod 15 from sliding and deflecting, and increase the stability of the movement of the control rod 15.

[0036] See also Figure 4 The outer circumference of the positioning rod 16 is fixedly connected to two limit blocks 18. The outer surface of each limit block 18 is slidably connected to the fixing seat 14 through a slot opened inside the fixing seat 14, thereby restricting the positioning rod 16 and preventing the positioning rod 16 from rotating with the control rod 15, so as to prompt the positioning rod 16 to always move laterally.

[0037] See also Figure 3 and Figure 4 The outer circumference of the control rod 15 is fixedly sleeved with a handwheel 19, and the outer circumference of the handwheel 19 is provided with equidistantly arranged anti-slip grooves. The handwheel 19 facilitates the operation of the control rod 15 and prevents hand slippage, providing convenience for workers.

[0038] See also Figure 1 、 Figure 2 and Figure 3 The outer circumference of the shell 4 is fixedly connected to four equidistantly arranged auxiliary rods 20. The outer circumference of each auxiliary rod 20 is slidably connected to the base 3 through a slot opened inside the base 3. The shell 4 can be installed through the auxiliary rod 20, which facilitates the correspondence between the positioning rod 16 and the positioning slot on the shell 4.

[0039] In the present embodiment, an elevator emergency lighting device is provided with a damper 7 and a spring 8, so that the emergency lighting can be cushioned when it is impacted. The control rod 15 drives the positioning rod 16 to be retracted and extended during the rotation process, so that the positioning rod 16 can position the housing 4, thereby achieving the effect of shock-absorbing protection for the emergency lighting, preventing the emergency lighting from being easily damaged, and facilitating the disassembly and maintenance of the emergency lighting. This solves the problem that when an elevator malfunctions, it may fall from a certain height, which may easily cause the emergency lighting to vibrate, resulting in damage to the emergency lighting and loss of lighting function.

[0040] It should be noted that the spring 8 and the damper 7 can support the base 3, so that the base 3 stays at a certain height, and the base 3 can be buffered and shock-absorbed by the damper 7 and the spring 8 when vibrating.

[0041] The working principle of the above embodiment is:

[0042] When the elevator fails and causes vibration, the force generated by the vibration will act on the damper 7 and the spring 8, which will buffer and reduce the shock of the base 3, and then provide shock-absorbing protection for the emergency light 5, preventing the emergency light 5 from being easily damaged by vibration and losing its lighting function. When the emergency light 5 needs to be disassembled and maintained, the control lever 15 can be rotated to drive the positioning rod 16 to move outward, so that the positioning rod 16 is moved out of the empty slot inside the shell 4, and the positioning restriction on the shell 4 is released, so that the shell 4 and the emergency light 5 can be removed from the inside of the base 3. When the emergency light 5 is installed, it is only necessary to rotate the control lever 15 to drive the positioning rod 16 back to the empty slot inside the shell 4 to reposition the shell 4.
