[0006] Preferably, an outlet is provided on a side of the outside of the storage tube away from the fixing plate, and a storage groove is provided in the storage tube.

[0007] Preferably, a reeling rod is rotatably connected inside the storage slot, and a warning tape is wound around the outside of the reeling rod.

[0008] Preferably, one end of the warning tape is fixed to the reel-up rod via Velcro, and the other end extends through the outlet to the outside of the storage tube and is fixedly connected to a card plate with an L-shaped structure.

[0009] Preferably, the storage tube has an open structure design at the top and bottom, and sealing covers are threadedly connected at the upper and lower ends of the storage tube.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 , the utility model provides a technical solution:

[0023] A warning sign for elevator maintenance comprises a storage tube 1, the outside of which is fixedly connected to a fixed plate 2, and a movable groove 5 is symmetrically provided on the side of the fixed plate 2 away from the storage tube 1, and a clamping plate 3 is rotatably connected inside the movable groove 5, and a rotating shaft 6 is fixed to the upper and lower ends of the clamping plate 3, and the rotating shaft 6 is rotatably connected to the inner wall of the movable groove 5, a torsion spring is sleeved on the outside of the rotating shaft 6, and the adjacent surfaces of the two clamping plates 3 are serrated surfaces, and the clamping plate 3 matches the movable groove 5.

[0024] Specifically, an outlet 10 is provided on a side of the storage tube 1 away from the fixing plate 2 , and a storage groove 7 is provided inside the storage tube 1 .

[0025] Specifically, a reel-in rod 8 is rotatably connected to the interior of the storage slot 7 , and a warning tape 9 is wound around the exterior of the reel-in rod 8 .

[0026] Specifically, one end of the warning tape 9 is fixed to the reel-up rod 8 via Velcro, and the other end extends through the outlet 10 to the outside of the storage tube 1 and is fixedly connected to a card plate 4 with an L-shaped structure.

[0027] Specifically, the storage tube 1 is designed with an open structure at the top and bottom, and sealing covers are threadedly connected at the upper and lower ends of the storage tube 1.

[0028] Specifically, both ends of the reeling rod 8 are rotatably connected to the sealing cover, and both ends of the reeling rod 8 are sleeved with a coil spring 11, and both ends of the coil spring 11 are fixedly connected to the reeling rod 8 and the sealing cover respectively.

[0029] Working principle: During operation, the user first folds the clamping plate 3 inside the movable groove 5 through the rotating shaft 6, so that the clamping plate 3 and the fixed plate 2 are relatively vertically distributed, and the torsion spring sleeved on the outside of the rotating shaft 6 is elastically squeezed and stored, and then the two clamping plates 3 are used to clamp and fix the fixed plate 2 on the edging surface on one side of the elevator door, and then the card plate 4 is manually pulled to extend the warning tape 9 from the storage slot 7 outlet 10 in the storage tube 1, and the winding rod 8 is pulled to rotate, and the winding spring 11 is elastically stored, and the card plate 4 is hooked on the edging on the other side of the elevator door, and the warning tape 9 is elastically pulled by the winding spring 11 to keep the warning tape 9 flat and pull the pull plate to be hooked and fixed on the edging on the other side to complete the shielding and warning of the elevator door. Subsequently, the card plate 4 is removed and the winding rod 8 is automatically driven by the winding spring 11 to retract and store the warning tape 9. Finally, the design of the sealing cover facilitates the replacement and maintenance of the winding rod 8 and the warning tape 9 in the storage slot 7.
