[0027] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Please see Figures 1 to 3This is the first embodiment of the present utility model. This embodiment provides an elevator maintenance safety protection device, including: a base 1, a limit plate 2 fixedly installed at the front end of the base 1, a groove 3 opened at the top end of the base 1, and a fastening mechanism 4 provided inside the groove 3;

[0031] The fastening mechanism 4 includes a motor 401, which is embedded in the front end of the limiting plate 2. A drive rod 402 is fixedly installed at the power output end of the motor 401. A drive gear 403 is fixedly installed at one end of the drive rod 402 that passes through the base 1. A driven gear 404 is rotatably connected to the outer wall of the drive gear 403.

[0032] Specifically, a rotating rod 405 extends from the inside of the driven gear 404, and threaded rods 406 are fixedly installed at both ends of the rotating rod 405.

[0033] Furthermore, the threaded rods 406 fixed at both ends of the rotating rod 405 have opposite thread textures, which can form a bidirectional threaded rod, and rotate under the transmission of the driving gear 403 and the driven gear 404.

[0034] Specifically, a slider 407 is slidably connected to the outer wall of the threaded rod 406, and a clamping plate 408 is fixedly installed on the top of the slider 407.

[0035] Furthermore, the two threaded rods 406 are respectively threaded to the corresponding sliders 407. By setting the thread texture in opposite directions, the two sliders 407 can drive the corresponding clamping plates 408 to slide back to back or relative to each other, thereby abutting against both sides of the elevator door opening to achieve a clamping and fixing effect. At the same time, the clamping plate 408 has an L-shaped structure to facilitate locking and fixing, which can prevent loosening and displacement.

[0036] Specifically, the outer wall of the clamping plate 408 is provided with a slot 5, and a positioning groove 6 is provided on one side of the slot 5 on the outer wall of the clamping plate 408. A through rod 7 extends out of the inside of the positioning groove 6.

[0037] Furthermore, the through rod 7 slides through the slot 5 and can be inserted into the positioning slot 6. Multiple through rods 7 are set according to the positioning slot 6 to seal the elevator door opening and prevent children or other external objects from entering and posing a threat to maintenance personnel.

[0038] Specifically, a sleeve 8 is fitted onto one end of the through rod 7 that extends out of the positioning groove 6, and a locking plate 9 is fixedly installed on the other end of the through rod 7 located inside the positioning groove 6.

[0039] Furthermore, the through rod 7 and the sleeve 8 form a telescopic rod that can automatically extend and retract following the displacement of the clamping plate 408, improving the overall applicability. At the same time, the through rod 7 is connected to the locking plates 9 at both ends, with one end slidingly engaging with the slide groove 3 and the locking groove 5 respectively, and the other end slidingly engaging with the sleeve 8. This effectively prevents the through rod 7 from falling off, thus avoiding gaps that would prevent the elevator door opening from being completely sealed.

[0040] In use, the base 1 is first placed inside the elevator doorway, and initially engaged with the edge of the elevator doorway by the limiting plate 2. The motor 401 works in conjunction with the motor, which drives the rotation rod 402, the active gear 403, and the driven gear 404. This drives the rotating rod 405 to rotate two threaded rods 406 with opposite threads, causing the two sliders 407 to slide relative to or away from each other along the sliding groove 3. This allows the clamping plate 408 to abut against and clamp onto the elevator doorway, securing the protective device. A telescopic rod is formed by the through rod 7 and the sleeve 8, automatically adjusting according to the displacement of the clamping plate 408. It also engages with the locking plate 9 and the locking groove 5, and passes through the positioning groove 6 to seal the elevator doorway, preventing external objects from entering. The protective device is equipped with a plug for connection to the public power distribution system at the maintenance location.

[0041] In summary, the base 1 and the limiting plate 2 work together to initially engage with the elevator doorway. At the same time, the two clamping plates 408 press against the inner walls of the elevator doorway, securing it and preventing loosening or shaking that could cause it to fall into the elevator shaft and endanger the lives of the staff. In addition, the retractable rod 7 and sleeve 8 can seal the elevator doorway to prevent children or external objects from entering. The L-shaped clamping plates 408 increase the load-bearing capacity from the outside into the elevator doorway, preventing it from being directly detached by large external forces, thus ensuring the safety of the staff inside the elevator shaft.

[0042] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which provides an improved design for an elevator maintenance safety protection device.

[0043] Specifically, a mounting groove 10 is provided on one side of the top slide groove 3 of the base 1, and a connecting mechanism 11 is provided inside the mounting groove 10.

[0044] Furthermore, by setting up the connecting mechanism 11, workers can attach to the safety rope, which further enhances the safety protection effect on top of the existing safety measures.

[0045] Specifically, the connecting mechanism 11 includes a connecting frame 1101, which is slidably connected inside the mounting groove 10, and a fixing rod 1102 is fixedly installed inside the connecting frame 1101.

[0046] Furthermore, the connecting frame 1101 can directly fasten one end of the safety rope via the fixed fixing rod 1102, improving the overall ease of use.

[0047] Specifically, a limiting hole 1103 is provided on one side of the outer wall of the connecting frame 1101, and a connecting rod 1104 extends out of the limiting hole 1103. A retaining ring 1105 is fixedly installed at one end of the connecting rod 1104 that enters the limiting hole 1103.

[0048] Furthermore, through the cooperation of the connecting rod 1104 and the locking ring 1105, the connecting frame 1101 can be pulled by the staff and pass through the placement slot 10 into the elevator shaft, thus avoiding friction between the safety rope and the elevator door opening, which could cause damage to the safety rope.

[0049] In use, the connecting frame 1101 slides out of the mounting slot 10 via the connecting rod 1104 and is located inside the elevator shaft. The connecting frame 1101 is prevented from detaching by the engaging ring 1105 and the limiting hole 1103. The safety rope is directly fastened via the fixing rod 1102, allowing the staff to add a safety rope on top of the normal protection measures. The rope also generates tension on the protection device from the inside. Together with the limiting plate 2 and the clamping plate 408, it can provide load-bearing capacity and improve the overall safety protection effect.

[0050] In summary, with the cooperation of the connecting rod 1104 and the locking ring 1105, the connecting frame 1101 is located inside the elevator shaft and directly fastens the safety rope via the fixing rod 1102. This further enhances the safety protection effect under conventional safety measures. In addition, the limiting plate 2 and the clamping plate 408 limit the elevator door opening, thereby improving the load-bearing capacity of the entire protection device for the safety rope and maintaining the stability of the protection device.
