[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A detachable elevator maintenance warning device comprises a mounting frame, a front side of the mounting frame is provided with positioning holes, the positioning holes are provided on four sides of the front side of the mounting frame near the corners, the front side of the mounting frame is slidably connected with a warning device body, the front side of the mounting frame is fixedly connected with a telescopic rod, the warning device body is located close to the inner side of the telescopic rod, the front side of the telescopic rod is clamped with a protective plate, the protective plate covers the front side of the warning device body, the inner side of the protective plate is fixedly connected with a sealing ring, the front side of the warning device body is provided with a limiting groove matching the sealing ring, the position of the limiting groove is symmetrical with the position of the sealing ring, a rectangular opening is provided on the protective plate, the rectangular opening passes through the protective plate, the inner side of the rectangular opening is fixedly connected with a protective film, the protective film covers the inner side of the rectangular opening, and the protective film The position of the membrane is symmetrical to that of the warning device body. The bottom end of the warning device body is fixedly connected to a support frame. Due to the presence of the protective plate, the position of the protective plate is adjusted by the telescopic rod, so that the front side of the warning device body can be effectively sealed and protected. The limiting groove can facilitate the insertion of the sealing ring. When the sealing ring is inserted into the limiting groove, the sealing ring can effectively seal the connection point between the protective plate and the warning device body, thereby preventing water from entering the warning device body through the connection point between the two and causing harm to it. Due to the presence of the protective film, the protective film can seal and protect the inner side of the rectangular opening without hindering the user from operating the warning device body, thereby effectively improving the waterproof performance of the warning device body.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] First, when in use, the position of the mounting frame can be effectively fixed through the positioning hole, and the protective plate can effectively protect the front side of the warning device body. The limiting groove can facilitate the insertion of the sealing ring. When the sealing ring is inserted into the limiting groove, the sealing ring can effectively seal the connection point between the protective plate and the warning device body, thereby preventing water from entering the warning device body through the connection point between the two and causing harm to it. Due to the existence of the protective film, the protective film can seal and protect the inner side of the rectangular opening without hindering the user from operating the warning device body, thereby effectively improving the waterproof performance of the warning device body. At the same time, the protective plate can also effectively prevent the warning device body from being directly bumped, thereby effectively improving the safety protection of the warning device body;

[0016] Secondly, due to the locking of the first clamping block, the position of the limit plate can be effectively limited, and the limit plate can prevent the position of the warning device body from being displaced. When the warning device body needs to be disassembled for maintenance, the first clamping slot is first pulled out through the protrusion, and then the limit plate is pulled out through the second sliding slot, and then the protective plate is removed through the clamping principle, and finally the warning device body is removed by pulling through the first sliding slot. While achieving the convenience of disassembly and assembly of the warning device body, it can also solve the problem of damage to the wall caused by disassembly and assembly of the mounting frame.
