Detailed Embodiment

[0018] The following describes the embodiments of the present utility model with reference to the drawings.

[0019] A warning sign for elevator maintenance, as Figures 1 - 5As shown in the figure, it includes an installation column 1, a warning sign body 6, a rotating plate 2, a sliding plate 3, a vertical rod 4 and a threaded rod 5. The top of the installation column 1 is fixedly connected with the warning sign body 6, and the warning sign body 6 is printed with Chinese-English bilingual warning signs. Both sides of the installation column 1 are rotatably connected with rotating plates 2. The sides of the rotating plates 2 away from each other are open. Both sides of the rotating plates 2 away from each other are slidably connected with sliding plates 3. Both sides of the sliding plates 3 away from each other are fixedly connected with vertical rods 4. The tops of the rotating plates 2 are rotatably connected with threaded rods 5, and the threaded rods 5 are all threadedly connected with the sliding plates 3. By controlling the forward and reverse rotation of the threaded rods 5, the sliding plates 3 can be made to approach or move away from each other, and the distance between the left and right vertical rods 4 can be controlled. When using this warning sign, place the installation column 1 at the door of the elevator to be repaired, make the warning sign body 6 located in the middle of the elevator door, and make the left and right vertical rods 4 closely adhere to the left and right sides of the elevator door, so as to block the elevator to be repaired, avoiding the warning failure caused by the movement of the warning sign body 6 due to external force factors. And the use of the vertical rod 4 can be assisted by rotating the rotating plate 2. When the warning sign body 6 is far away from the elevator door, it does not affect the use of the vertical rod 4, and people can see the warning sign body 6 from a distance, enhancing the warning effect of this warning sign.

[0020] As Figures 1 - 3 shown, it also includes a rotating seat 7, an elastic member 8 and a wedge block 9. Both sides of the left and right vertical rods 4 are rotatably connected with two rotating seats 7. Both sides of the left and right rotating seats 7 away from each other are slidably connected with two wedge blocks 9. The inclined surfaces of the wedge blocks 9 are located on the sides of the left and right wedge blocks 9 away from each other. Elastic members 8 are fixedly connected between the wedge blocks 9 and the vertical rods 4. When the vertical rods 4 are closely adhered to the edge of the elevator door, the wedge blocks 9 move towards the direction close to the elevator door, so that the edge of the elevator door presses the inclined surfaces of the wedge blocks 9, causing the left and right wedge blocks 9 to approach and slide towards each other and compress the elastic members 8, thereby fixing this warning sign at the elevator door. When it is necessary to remove this warning sign, move the vertical rods 4 away from the elevator door, the wedge blocks 9 move away from the elevator door, and the elastic members 8 return to their original state to reset the wedge blocks 9, which can reinforce this warning sign during use and improve the anti-interference ability of this warning sign.

[0021] As Figure 1 , Figure 4 and Figure 5As shown in the figure, it also includes a reinforcement base 11, a sliding block 12, a universal wheel 13 and a clamping block 14. Two reinforcement bases 11 are fixedly connected to the bottoms of the left and right vertical rods 4. The middle parts of the reinforcement bases 11 are slidably connected with the sliding blocks 12. Universal wheels 13 are installed at the bottoms of the sliding blocks 12. Card slots are opened on the left and right sides of the reinforcement bases 11 and the sliding blocks 12. The corresponding two sliding blocks 12 are clamped by the clamping blocks 14. The clamping blocks 14 are all located in the card slots. The clamping blocks 14 are used to fix the universal wheels 13 to the reinforcement bases 11. Initially, the reinforcement bases 11 are in contact with the ground. When it is necessary to move this warning sign, first move the left and right clamping blocks 14 away from the reinforcement bases 11, then move the universal wheels 13 downward to make the reinforcement bases 11 away from the ground, and then reconnect the clamping blocks 14 with the sliding blocks 12. When it is necessary to place this warning sign at the elevator door, just reverse the above steps. The universal wheels 13 can improve the mobility of this warning sign, and when using this warning sign, the reinforcement bases 11 can further improve the stability of this warning sign.

[0022] As Figure 1 and Figure 3 shown in the figure, it also includes a rotating rod 15, a connecting rod 16 and a sliding frame 17. Rotating rods 15 are rotatably connected to the upper and lower sides of the warning sign body 6. Connecting rods 16 are hinged to the mutually remote sides of the upper and lower rotating rods 15. Sliding frames 17 are slidably connected to the outer sides of the left and right vertical rods 4. The mutually close sides of the left and right sliding frames 17 are both open. The connecting rods 16 are hingedly connected to the corresponding sliding frames 17. The connecting rods 16 are all located within the sliding frames 17. When the left and right sliding plates 3 approach each other, the upper and lower sliding frames 17 move away from each other. When the left and right sliding plates 3 move away from each other, when the rotating plate 2 is rotated, the rotating rods 15 all rotate, and the connecting rods 16 can form an obstacle in the middle of the elevator door, further improving the stability of this warning sign and also further improving the warning effect of this warning sign.

[0023] As Figures 1 - 3 shown in the figure, it also includes a warning light 10. Warning lights 10 with reflective strips are installed on the tops of the vertical rods 4. When the elevator is being repaired, the glowing warning lights 10 can quickly attract people's attention, further improving the warning effect of this warning sign.

[0024] As Figure 1 and Figure 2 shown in the figure, it also includes a handwheel 51. Handwheels 51 are fixedly connected to the mutually close sides of the left and right threaded rods 5. Anti-slip patterns are opened on the outer sides of the handwheels 51. When rotating the threaded rods 5, by manually rotating the threaded rods 5 through the handwheels 51, the use of the threaded rods 5 can be facilitated to achieve fine position adjustment, further improving the stability of this warning sign.

[0025] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
