[0029] See also Figure 1-5 The utility model provides a technical solution: a warning sign for elevator maintenance, comprising a support frame 1 for elevator maintenance, a warning plate 4 is fixed at the bottom of the support frame 1, a plurality of reflective plates 5 are bonded to one side of the warning plate 4, a warning slogan 6 is pasted at the center of the warning plate 4, and an obvious warning mark is printed on the warning slogan 6, such as "Maintenance, Do Not Enter" and other words to attract the attention of pedestrians, an installation component 2 is arranged on the upper side of the warning slogan 6, and a prompt component 3 is arranged on one side of the installation component 2;
[0030] In order to facilitate installation, an installation component 2 is provided, which includes a fixing frame 21 and a slide bar 23. A plurality of locking grooves 29 are provided on one side of the top of the slide bar 23. A first rubber plate 22 is fixed to one end of the slide bar 23. A slide plate 210 is slidably connected to the inner wall of the fixing frame 21. A pull rod 211 is fixed to the top of the slide plate 210. The pull rod 211 is pulled upward, and then the first rubber plate 22 is pulled to one side so that the first rubber plate 22 is attached to the other side of the elevator door. A first rubber plate 22 is fixed to the bottom of the slide plate 210 and inserted into the inner side of the locking groove 29. The locking rod 28 of the support frame 1 is provided with a first sliding groove 26 on one side, and a second sliding groove 27 is provided on the inner wall of the first sliding groove 26. A slider 25 is fixed to the outer side of the sliding rod 23, and the outer side of the slider 25 is slidably connected to the inner side of the second sliding groove 27. The pull rod 211 is released. At this time, under the elastic force of the spring 212, the locking rod 28 is pushed to slide on the outer side of the sliding rod 23, and then the sliding rod 23 is continued to be pushed to one side so that the locking rod 28 is inserted into the inner side of the corresponding locking groove 29, and the outer side of the sliding rod 23 is slidably connected to the inner side of the first sliding groove 26.
[0031] A spring 212 is sleeved on the outside of the pull rod 211, and the two ends of the spring 212 are respectively connected to one side of the slide plate 210 and the inner wall of the fixing frame 21. A second rubber plate 24 is fixed to the end of the support frame 1 away from the sliding rod 23. The bottom of the fixing frame 21 is fixed to the top side of the support frame 1. By pulling the sliding rod 23 of different lengths to one side, the warning sign can be installed on the side of elevator doors of different widths, thereby improving the versatility of the warning sign when in use.
[0032] In order to prevent pedestrians from mistakenly entering the elevator under maintenance, a prompt component 3 is provided. The prompt component 3 includes a protective cover 31. A warning light 34 and a battery 35 are fixed to the inner wall of the protective cover 31 respectively. A maintenance door is installed on one side of the protective cover 31 for charging the battery 35. When the first photoelectric switch 32 or the second photoelectric switch 33 senses that someone is passing by, an electrical signal is sent to the warning light 34. The first photoelectric switch 32 is installed on the top of the support frame 1, and the second photoelectric switch 33 is installed on the bottom of the warning plate 4. The warning light 34 generates sound and light prompts to actively inform maintenance personnel that a pedestrian has mistakenly entered the interior of the maintenance elevator. The output end of the battery 35 is electrically connected to the input end of the first photoelectric switch 32 and the input end of the second photoelectric switch 33 respectively. The output end of the first photoelectric switch 32 and the output end of the second photoelectric switch 33 are electrically connected to the input end of the warning light 34. The entry of the pedestrian is detected in real time, and the warning light 34 is triggered in time for prompting, which is helpful to timely discover and solve potential safety risks and avoid accidents caused by failure to timely discover pedestrians.
[0033] Working principle: When the elevator is under maintenance, the second rubber plate 24 on one side of the support frame 1 is pressed against one side of the elevator door, so that the warning plate 4 is vertically located on the lower side of the support frame 1, and then the pull rod 211 is pulled upward, and then the first rubber plate 22 is pulled to one side, so that the first rubber plate 22 is attached to the other side of the elevator door, and then the pull rod 211 is released. At this time, under the elastic force of the spring 212, the lock rod 28 is pushed to slide on the outside of the slide rod 23, and then the slide rod 23 is continued to be pushed to one side, so that the lock rod 28 is inserted into the corresponding lock groove 29. At this time, the installation of the warning sign is completed. By pulling slide rods 23 of different lengths to one side, the warning sign can be installed on one side of elevator doors of different widths, thereby improving the versatility of the warning sign when in use.
[0034] When the elevator is under maintenance, if a pedestrian mistakenly enters the elevator, no matter if he enters from the upper side or the lower side of the warning plate 4, he will pass by one side of the first photoelectric switch 32 or the second photoelectric switch 33. When the first photoelectric switch 32 or the second photoelectric switch 33 senses that someone is passing by, an electrical signal is sent to the warning light 34, and the warning light 34 generates sound and light prompts to actively inform the maintenance personnel that a pedestrian has mistakenly entered the maintenance elevator. Through the setting of the first photoelectric switch 32 and the second photoelectric switch 33, the entry of the pedestrian can be detected in real time, and the warning light 34 can be triggered in time to give a prompt, which helps to timely discover and resolve potential safety risks and avoid accidents caused by failure to timely discover pedestrians.
