[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] Example:

[0024] This embodiment discloses an emergency evacuation lighting sign lamp, see Figures 1 to 5 , including a mounting frame 1 with one side open, a sign light panel 2 and a telescopic mechanism 3.

[0025] like Figure 1 , Figure 5 As shown, the sign light board 2 is arranged inside the open side of the installation frame 1. The sign light board 2 is rectangular, and the side of the sign light board 2 is connected to the inner wall of the installation frame 1 to limit and protect the sign light board 2. A U-shaped connecting plate 201 is provided on the side of the sign light board 2 relative to the telescopic mechanism 3, and an insertion cavity is formed between the U-shaped connecting plate 201 and the sign light board 2 for installing and fixing the sign light board 2.

[0026] like Figures 1 to 5 As shown, the telescopic mechanism 3 is arranged between the mounting frame 1 and the sign light board 2.

[0027] Specifically, Figures 1 to 5As shown, the telescopic mechanism 3 includes a threaded sleeve 301 and a rack 302. The closed end of the threaded sleeve 301 is rotatably connected to the inner wall of the installation frame 1. The rack 302 is arranged at the top of the threaded sleeve 301. The threaded sleeve 301 is internally threaded with a stud 303. The stud 303 is fixedly connected to an L-shaped plug block 304 at the end opposite to the sign light board 2. One end of the L-shaped plug block 304 is penetrated between the U-shaped connecting plate 201 and the sign light board 2 to form an insertion cavity. The top surface of the other end of the L-shaped plug block 304 is connected to the bottom surface of the U-shaped connecting plate 201. A gear ring 305 is fixedly sleeved on the surface of the threaded sleeve 301. The gear ring 305 is meshed with the rack 302. One end of the rack 302 is fixedly connected to a guide rod 306. One end of the guide rod 306 is penetrated through the frame wall of one end of the installation frame 1 and is detachably connected to a pull rod 307. When the sign light board 2 When the light board 2 needs maintenance and repair, the guide rod 306 is pulled outward, and the rack 302 drives the threaded sleeve 301 to rotate through the gear ring 305. Since the mounting frame 1 limits the sign light board 2, the stud 303 does not rotate, so the rotation of the threaded sleeve 301 drives the stud 303 to spirally separate from the threaded sleeve 301, and the sign light board 2 is pushed out from the open side of the mounting frame 1. The sign light board 2 is lifted upward to separate the L-shaped plug block 304 from the insertion cavity formed between the U-shaped connecting plate 201 and the sign light board 2. The sign light board 2 can be maintained and repaired, and the U-shaped connecting plate 201 on the sign light board 2 is inserted into the L-shaped plug block 304. The sign light board 2 is supported by the hand and the guide rod 306 is pushed inward, so that the threaded sleeve 301 and the stud 303 can be spirally tightened to collect the sign light board 2 into the open side of the mounting frame 1.

[0028] Further, such as Figure 3 As shown, a T-shaped slot 3061 is provided at one end of the guide rod 306, and a T-shaped plug 3071 is provided at one end of the pull rod 307 relative to the guide rod 306. One end of the guide rod 306 and the pull rod 307 are detachably connected through the T-shaped slot 3061 and the T-shaped plug 3071, so that the guide rod 306 can be easily pulled through the pull rod 307. At the same time, the detachable connection between one end of the guide rod 306 and the pull rod 307 through the T-shaped slot 3061 and the T-shaped plug 3071 can prevent the sign light board 2 from falling off due to accidental touching.

[0029] Further, if Figure 3 As shown, the guide rod 306 is rectangular, and a through hole 101 adapted for the guide rod 306 is opened in the frame wall at one end of the mounting frame 1. One end of the guide rod 306 is passed through the through hole 101. The through hole 101 is used to limit the guide rod 306 to prevent the guide rod 306 and the rack 302 from offset.

[0030] It is worth noting that if Figure 2As shown, a spring 308 is provided on one side of the rack 302, one end of the spring 308 is fixedly connected to the surface of one side of the rack 302 through a hook, and the other end of the spring 308 is fixedly connected to the other inner wall of the installation frame 1 through a hook. When the rack 302 moves toward the through hole 101, the spring 308 is stretched. After the sign light board 2 is maintained and overhauled, the pull rod 307 is loosened, the spring 308 is reset, and the sign light board 2 is driven to enter the open side of the installation frame 1.

[0031] It is worth noting that Figure 1 , Figure 4 As shown, one closed end of the threaded sleeve 301 is fixedly connected to a rotating shaft 3011, one end of the rotating shaft 3011 is fixedly connected to a limiting ring 3012, a rotating groove 102 adapted to the rotating shaft 3011 is provided at a position of the mounting frame 1 relative to the rotating shaft 3011, and a limiting groove 103 adapted to the limiting ring 3012 is provided along one end of the rotating groove 102. The threaded sleeve 301 rotates, driving the rotating shaft 3011 and the limiting ring 3012 to rotate in the rotating groove 102 and the limiting groove 103 respectively. The diameter of the rotating groove 102 is smaller than the diameter of the limiting groove 103, so as to prevent the threaded sleeve 301 from falling off.

[0032] Working principle: When the utility model needs to maintain and overhaul the sign light board 2, the maintenance personnel take out the pull rod 307, insert the T-shaped plug 3071 on the pull rod 307 into the T-shaped slot 3061 at one end of the guide rod 306, and pull the pull rod 307 to the outside of the installation frame 1 by hand. The pull rod 307 drives the guide rod 306 to move outward along the through hole 101, and the rack 302 drives the threaded sleeve 301 to rotate through the gear ring 305. At the same time, the spring 308 is stretched, and the threaded sleeve 301 rotates, driving the rotating shaft 3011 and the limiting ring 3012 to rotate in the rotating groove 102 and the limiting groove 103 respectively. Since the installation frame 1 limits the sign light board 2, the stud 303 does not rotate, so the threaded sleeve The rotation of 301 drives the stud 303 to spirally separate from the threaded sleeve 301, and the sign light board 2 is pushed out from the open side of the installation frame 1. The sign light board 2 can be lifted up to separate the L-shaped plug block 304 from the insertion cavity formed between the U-shaped connecting plate 201 and the sign light board 2, so that the sign light board 2 can be maintained and repaired. The U-shaped connecting plate 201 on the sign light board 2 is inserted into the L-shaped plug block 304, and the sign light board 2 is supported by the hand. The pull rod 307 and the spring 308 are reset to allow the threaded sleeve 301 and the stud 303 to be spirally tightened to collect the sign light board 2 into the open side of the installation frame 1, and the T-shaped plug block 3071 on the rod 307 can be taken out from the T-shaped slot 3061 at one end of the guide rod 306.

[0033] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
