On the contrary, the embodiments of the present invention include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0022] The elevator maintenance warning device according to the embodiments of the present invention will be described below with reference to the drawings.

[0023] The elevator maintenance warning device provided by the embodiments of the present invention can be applied to the warning of elevator maintenance. By reducing the volume of the warning device, the portability of the warning device is enhanced, so that maintenance personnel can more easily and conveniently carry the warning device to the elevator maintenance site.

[0024] As Figures 1-3 shown, the elevator maintenance warning device according to the embodiments of the present invention may include a warning component 1, a support mechanism 2 and a limiting mechanism 3.

[0025] It should be noted that a maintenance board can be installed on the front surface of the warning component 1 described in the above embodiments.

[0026] Among them, two sets of support mechanisms 2 are provided, and the warning component 1 is installed between the two sets of support mechanisms 2.

[0027] It should be noted that the support mechanism 2 described in the above embodiments is fixed on the door frame in front of the elevator.

[0028] The limiting mechanism 3 is installed at both ends of the warning component 1, and the warning component 1 is clamped with the support mechanism 2 through the limiting mechanism 3.

[0029] It can be understood that under the action of the limiting mechanism 3, the fixing between the support mechanism 2 and the warning component 1 after storage can be completed.

[0030] Specifically, during the actual operation, when relevant personnel repair the elevator, they carry the warning device after it is stored. After arriving at the repair location, one set of support mechanisms 2 is fixed on the side frames of the landing door. Subsequently, the other set of support mechanisms 2 is opened from the warning assembly 1 under the action of the limit mechanism 3. Then, the other set of support mechanisms 2 is pulled, the banner in the middle of the warning assembly 1 is pulled out, and the other set of support mechanisms 2 is fixed, thereby completing the fixation effect of the warning assembly 1 during elevator repair. By reducing the volume of the warning device, the portability of the warning device is enhanced, enabling maintenance personnel to carry the warning device to the elevator repair site more easily and conveniently.

[0031] In an embodiment of the present invention, as Figures 1-2 shown, the warning assembly 1 may include a warning box 11, a warning strip 12, a rotating rod 13, and a torsion spring 14.

[0032] It should be noted that multiple warning slogans can be written on the warning strip 12 described in the above embodiment.

[0033] Among them, the torsion spring 14 is installed at both ends inside the warning box 11. Both ends of the rotating rod 13 are rotatably connected to the torsion spring 14. The warning strip 12 is wound around the outside of the rotating rod 13. A notch for the warning strip 12 to pass through is opened at the bottom end of the warning box 11. The bottom end of the warning strip 12 is connected to one set of support mechanisms 2.

[0034] Specifically, under the pulling of the other set of support mechanisms 2, the warning strip 12 rotates under the action of the rotating rod 13 and is fixed by the other set of support mechanisms 2 to complete the installation of the warning device. After the elevator repair is completed, the other set of support mechanisms 2 is removed, and under the action of the torsion spring 14, the warning strip 12 is wound up in the warning assembly 1, improving the efficiency of storing the warning strip 12.

[0035] In an embodiment of the present invention, as Figures 1-2 shown, the support mechanism 2 may include a support box 21, a fixing component 22, a partition 23, and a threaded rod 24.

[0038] Specifically, under the action of the fixing component 22, the threaded rod 24 is rotated out of the support box 21 and abuts against the elevator hall door frame under the action of the fixing component 22, thereby completing the installation of the warning component 1.

[0039] In an embodiment of the present utility model, as Figures 1-2 shown, the fixing component 22 may include a rotating ring 221, a bottom plate 223, a rubber plate 224 and a rotating ring 225.

[0040] It should be noted that the rubber plate 224 described in the above embodiment has the effect of increasing the friction between the bottom plate 223 and the hall door frame, ensuring the stability of the fixing component 22 after fixation.

[0041] Among them, anti-slip grooves 222 are provided on the outer side of the rotating ring 221. The rotating ring 221 is rotatably connected to both ends of the support box 21 through the rotating ring 225. The bottom plate 223 is fixedly connected to the other end of the threaded rod 24, and the rubber plate 224 is fixedly connected to one end of the bottom plate 223.

[0042] Specifically, under the rotation of the rotating ring 221 and the rotating ring 225, the threaded rod 24 is rotated out of the support box 21 until the bottom plate 223 and the rubber plate 224 come into contact with the hall door frame, and then ensuring that the rotating ring 221 cannot continue to rotate can ensure the firmness of the warning component 1 after being fixed on the hall door frame.

[0043] In an embodiment of the present utility model, as Figures 1-2 shown, the limiting mechanism 3 may include a plug rod 31 and a limiting component 32.

[0046] Specifically, under the connection of the plug rod 31 and the limiting component 32, the other set of support mechanisms 2 is fixed below the warning component 1.

[0047] In an embodiment of the present utility model, as Figures 1-2 shown, the limiting component 32 may include a fixing plate 321, a pressing plate 322 and an elastic pin rod 323.

[0048] It should be noted that the pressing plate 322 described in the above embodiment is an elastic plate.

[0049] Among them, the fixed plate 321 is connected to the warning component 1, the elastic pin rod 323 is connected to the insertion rod 31, a pin hole for the elastic pin rod 323 to be clamped is formed on the fixed plate 321, the pressing plate 322 is installed on the front surface of the fixed plate 321, and the pressing plate 322 is arranged in front of the pin hole.

[0050] Specifically, after the insertion rod 31 is clamped into the fixed plate 321, the elastic pin rod 323 is clamped into the pin hole, and the fixation of another set of support mechanisms 2 can be completed. Subsequently, under the action of the pressing plate 322, the release of the insertion rod 31 from the fixed plate 321 is completed.
