[0002] The elevator maintenance warning device is a device specially used to send out warning information when the elevator is undergoing maintenance. Its main function is to remind passengers and related personnel that the elevator is undergoing maintenance to avoid accidents.

[0003] Many common elevator maintenance warning devices are static. Static warning devices usually include maintenance notices and warning signs posted at or around the elevator door. These static signs can clearly inform people that the elevator is under maintenance and cannot be used. Then there is the following problem: it may not be easy to notice at certain angles, or it may not be eye-catching enough. This may cause some people to approach or try to use the elevator without realizing that the elevator is under maintenance in time, which may bring certain safety hazards. In order to improve it, a warning device for elevator maintenance is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A warning device for elevator maintenance and repair comprises a base 1, a screw rod 2 is rotatably provided on the upper end surface of the base 1, a lower motor connected to the screw rod 2 is provided inside the base 1, a first support frame 4 and a second support frame 7 are installed on the upper end surface of the base 1, a sleeve 3 is threadedly provided on the screw rod 2, the sleeve 3 is connected to the first support frame 4 through a connecting mechanism, a rotating rod 10 is rotatably installed on the sleeve 3, a rotating cylinder 8 is provided on the rotating rod 10 through a connecting mechanism, a plurality of warning signs 9 are installed on the rotating cylinder 8, and the plurality of warning signs 9 are adhesively connected to the rotating cylinder 8. As shown in the figure, four warning signs 9 are provided, and the warning words on the surface of the above-mentioned warning signs 9 are different, and 360° display is achieved by rotation.

[0022] An upper motor 13 is mounted on the first support frame 4 , a transmission gear 16 is sleeved on the outside of the rotating rod 10 , the upper motor 13 is connected to the transmission gear 16 via a rotating mechanism, and the transmission gear 16 is connected to the second support frame 7 via a limiting mechanism.

[0023] The connecting mechanism includes a limiting rod 6 installed on the outer wall of the sleeve 3. The first support frame 4 is provided with a limiting opening 5 corresponding to the limiting rod 6. The limiting rod 6 is located in the limiting opening 5 to prevent the sleeve 3 from rotating with the screw 2, thereby playing a limiting role for the sleeve 3.

[0024] The connecting mechanism includes a connecting block 11 installed at the end of the rotating rod 10, and the bottom wall of the rotating cylinder 8 is provided with a connecting groove 12 corresponding to the connecting block 11. As shown in the figure, the rotating cylinder 8 can be connected to the rotating rod 10 by relying on the above-mentioned connecting block 11 and the connecting groove 12, so that the rotating cylinder 8 can rotate synchronously when the rotating rod 10 rotates.

[0025] The rotating mechanism includes a driving gear 14 installed on the output shaft of the upper motor 13, and the driving gear 14 is meshed with the transmission gear 16. As shown in the figure, the meshing of the driving gear 14 and the transmission gear 16 realizes the power transmission of the upper motor 13, and finally drives the rotating rod 10, the rotating cylinder 8 and the warning sign 9 to rotate.

[0026] The limiting mechanism includes a connecting frame 15 arranged on the second support frame 7, a limiting block 18 is installed on the connecting frame 15, and an annular groove 17 is provided on the transmission gear 16. The limiting block 18 is located in the annular groove 17 to prevent the transmission gear 16 from being separated from the connecting frame 15, thereby ensuring its stability in the position above the base 1.

[0027] The cross-sectional views of the rotating rod 10, the connecting block 11 and the connecting groove 12 are all regular hexagons, the vertical cross-sectional views of the first support frame 4 and the second support frame 7 are all L-shaped, and the vertical cross-sectional view of the connecting frame 15 is U-shaped. The above shapes can all be referred to as shown in the accompanying drawings. The above status quo is to better connect with other equipment components, and can all be manufactured relying on existing technical equipment.

[0028] When the utility model is used, the warning sign 9 is glued and installed on the rotating cylinder 8. After the upper motor 13 is started, the driving gear 14 can be driven to rotate. The driving gear 14 can drive the rotating rod 10 to rotate by the transmission gear 16. The rotation of the rotating rod 10 can drive the rotating cylinder 8 to rotate by the connecting block 11, so that multiple warning signs 9 can be displayed by 360° rotation. The 360° rotation display has the following advantages:

[0029] Enhance visibility: People can see the warning words no matter from which angle they watch, which improves the effectiveness of information communication. Improve attention: Dynamic rotating displays are more likely to attract people's attention and can attract more attention than static displays. All-round coverage: Ensure that people in all directions around the cylinder can receive warning information. Avoid visual blind spots: Eliminate the situation where warning words may not be seen at certain angles. Increase interest: Make the warning method more attractive and innovative, which helps to increase people's attention and memory of the warning content. Improve warning effect: Better remind people to pay attention to relevant matters, thereby reducing potential dangers or errors. Adapt to different positions: It is convenient for people in different positions to obtain information without having to go to a specific angle to check. Enhance visual impact: Leave a deeper impression on people and further strengthen the warning effect.

[0030] In this solution, the height of the rotating cylinder 8 and the warning sign 9 can be adjusted. The lower motor is started to drive the screw 2 to rotate. When the screw 2 rotates, the sleeve 3 can be raised or lowered relative to the base 1, thereby relying on the rotating rod 10 to drive the rotating cylinder 8 and the warning sign 9 to achieve height adjustment. After it is raised, it has the following advantages:

[0031] Adapt to different scene requirements: The height can be adjusted according to the specific installation location and surrounding environment to achieve better visual effects and warnings. Improve visibility range: Taller cylinders can be seen at a longer distance, expanding the coverage of warnings; while shorter cylinders may be more suitable for warnings in certain close distances and specific areas. Enhance flexibility: The height can be flexibly changed according to actual conditions, such as lowering the height when space is limited and increasing the height when it needs to be highlighted.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
