Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator maintenance technology, specifically to an elevator inspection door frame that can prevent movement. Background Technology
[0002] When inspecting an elevator, its use is often suspended to prevent accidents. This requires sealing the elevator doors during the inspection. However, existing elevator door sealing devices are mainly folding panels composed of two or more wide plates, similar to screens, but they are relatively small. This device is not only not secure when sealing the door, but it can also move when bumped.
[0003] A search revealed a patent publication number CN212982137U published on April 16, 2021, for an anti-moving elevator inspection sealing device. The device is broadly described as including a main frame with two sets of protective folding auxiliary frames. An axially driven spreading device is also installed inside the main frame. This invention utilizes spreading devices at both ends of the main frame. A driving block rotates, causing a lead screw to move outwards, thus abutting against the side wall next to the elevator from both ends. The spreading at both ends forms a stable fixation, and baffles and auxiliary rods prevent rotation, further improving stability. The folding auxiliary frames on both sides of the main frame can be unfolded and folded. Rotation of the connecting block raises the vertical rod, and the horizontal rod connected to the end of the vertical rod rotates, causing it to unfold to both sides of the main frame to form protection. Folding it down reduces the volume and facilitates transportation.
[0004] While the aforementioned existing technical solution can prevent movement during collisions and facilitate transportation, the device cannot adjust its width, making it unsuitable for elevator doors of various widths and limiting its applicability. Utility Model Content

[0014] Optionally, the vertical rod is provided with a positioning block, and the rotating seat is provided with a plurality of positioning grooves that cooperate with the positioning block.

[0016] Optionally, the intermediate component is provided with evenly distributed anti-slip bars.
[0017] By adopting the above technical solution, the anti-slip bar is used to facilitate the rotation of the intermediate parts and the bidirectional threaded rod by personnel, thereby saving manpower.
[0018] (III) Beneficial Effects

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.
[0030] Reference Figures 1-6 A movable elevator inspection door seal includes a bidirectional threaded rod 1, multiple first threaded components 2 and multiple second threaded components 3, located on both sides of the bidirectional threaded rod 1.

A first threaded rod 4 is rotatably connected to the interior of a first threaded component 2 near its left end, and the first threaded rod 4 is threadedly connected to an adjacent first threaded component 2. A second threaded rod 5 is rotatably connected to the interior of a second threaded component 3 near its right end, and the second threaded rod 5 is threadedly connected to an adjacent second threaded component 3. Both the first threaded rod 4 and the second threaded rod 5 have cross sliding grooves. A cross connecting piece 6 is slidably connected between adjacent first threaded rods 4 and adjacent second threaded rods 5. Rotating seats 7 are provided at the top and bottom ends of the first threaded components 2 and the second threaded components 3. A third screw 8 is threaded onto the rotating base 7. One end of the third screw 8 is rotatably connected to a vertical rod 9, and one end of the vertical rod 9 is rotatably connected to a horizontal rod 10. The horizontal rod 10 has a through groove, and a connecting rod 11 is slidably connected between adjacent through grooves. Stop plates 12 are fixedly connected to the horizontal rods 10 near the four corners. An intermediate part 13 is provided on the bidirectional threaded rod 1. When the equipment is moved to a designated position, rotating the intermediate part 13 drives the bidirectional threaded rod 1 to rotate. The bidirectional threaded rod 1 drives the first threaded part 2 and the second threaded part 3 to move. The bidirectional threaded rod 1 drives multiple first threaded rods 4 and second threaded rods 5 to rotate simultaneously through the connection between the first threaded rod 4, the second threaded rod 5 and the cross connector 6. This drives multiple first threaded parts 2 and second threaded parts 3 to move equidistantly, thereby unfolding the equipment and facilitating its adjustment, thus improving the applicability of the equipment.
[0031] Reference Figure 1 and Figure 2 The stop plate 12 is provided with an anti-slip pad 14, which is used to increase the friction between the stop plate 12 and the elevator door frame, thereby improving the stability of the equipment.

[0033] Reference Figure 5 and Figure 6 The vertical rod 9 is equipped with a positioning block 18, and the rotating seat 7 has a plurality of positioning grooves 19 that cooperate with the positioning block 18. When the vertical rod 9 drives the horizontal rod 10 to unfold, the third screw 8 is rotated to drive the vertical rod 9 to move.

[0034] Reference Figure 1 The intermediate part 13 is provided with evenly distributed anti-slip bars 20. The anti-slip bars 20 are used to facilitate the rotation of the intermediate part 13 and the bidirectional threaded rod 1 by personnel, thereby saving manpower.
[0035] In summary, the working principle and process of this movable elevator inspection door sealing frame are as follows: During use, the equipment is first moved to the designated position. Rotating the intermediate component 13 drives the bidirectional threaded rod 1 to rotate. The bidirectional threaded rod 1 drives the first threaded component 2 and the second threaded component 3 to move. Through the connection between the first threaded rod 4, the second threaded rod 5, and the cross connector 6, the bidirectional threaded rod 1 drives multiple first threaded rods 4 and second threaded rods 5 to rotate simultaneously, thereby driving multiple first threaded components 2 and second threaded components 3 to move equidistantly. This unfolds the equipment, facilitating adjustment and increasing its applicability. The anti-slip pad 14 is used to raise the stop plate 1. 2. The friction between the device and the elevator door frame is used to improve the stability of the equipment. When the device is installed on the elevator door frame, the tension spring 17 drives the auxiliary clamping plate 16 to fit tightly against the inner side of the elevator door frame, so that the auxiliary clamping plate 16 and the stop plate 12 cooperate to clamp the device on the elevator door frame, thereby improving the stability of the device. When the vertical rod 9 drives the horizontal rod 10 to unfold, the third screw 8 is rotated to drive the vertical rod 9 to move. The vertical rod 9 drives the positioning block 18 to insert into the positioning groove 19, thereby positioning the vertical rod 9 and improving the stability of the device. The anti-slip bar 20 is used to facilitate the rotation of the intermediate part 13 and the bidirectional threaded rod 1 by personnel, thereby saving manpower.
