DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] As Figures 1-5 Indicated, the utility model provides a kind of elevator maintenance construction safety device, including three groups of frame 1, two adjacent frame 1 between being equipped with fixed part 2, and two adjacent fixed part 2 are hinged by connecting part 3, still include:

[0027] Adjusting assembly, it is set on frame 1, for control the range of elevator shielding;

[0028] Wherein, adjusting assembly includes sliding groove 4, and sliding groove 4 is located at the both ends of the top of frame 1, and the inside of each group of sliding groove 4 is slidably connected with fixed frame 6, and one side of fixed frame 6 is provided with positioning plate 7, and positioning plate 7 is fixed with curtain 8 by cooperation screw, and one side of one group of movable rod 5 is provided with several groups of buckle slot 10, and one side of sliding groove 4 is fixed with fixed block 15, and fixed block 15 is hinged with buckle 16 by cooperation torsion spring;

[0029] Tensioning structure, it is set on frame 1, for curtain 8 tension;

[0030] Wherein, tensioning structure includes slot 11, and slot 11 is arranged in the inside of frame 1, and fixed shaft 12 is fixed in the inside of slot 11, and movable frame 13 and compression spring 14 are sleeved on the outer surface of fixed shaft 12, and rotating shaft 9 is rotatably connected in the inside of frame 1.

[0031] Through the cooperation between the sliding groove 4 and the movable rod 5, the movable rod 5 can move up and down along the outer surface of the sliding groove 4. When the movable rod 5 moves upward, the inclined edge of the clamping groove 10 will extrude the inclined surface of the buckle 16 and push the buckle 16 outward. When the movable rod 5 stops moving, the fixed frame 6 is clamped with the clamping groove 10 under the action of the torsion spring, which limits the downward movement of the movable rod 5, and thus the movable rod 5 can be automatically positioned, facilitating the quick adjustment of the height of the curtain 8.

[0032] As shown in Figure 4 , the buckle 16 is L-shaped, and the top end of the buckle 16 is provided with a chamfer.

[0033] Through the cooperation between the buckle 16 and the fixed block 15, the buckle 16 can rotate along the outer surface of the fixed block 15. At this time, the torsion spring will exert a spring force on the buckle 16, so as to drive the buckle 16 to be clamped with the clamping groove 10.

[0034] As shown in Figure 4 , the buckle 16 is clamped with the clamping groove 10, and the right angle edge of the buckle 16 blocks the clamping groove 10.

[0035] Through the cooperation between the buckle 16 and the clamping groove 10, when the end of the buckle 16 is embedded in the inside of the clamping groove 10, the right angle edge of the buckle 16 blocks the clamping groove 10, thereby limiting the downward movement of the movable rod 5 and directly positioning the movable rod 5.

[0036] As shown in Figure 5 , the bottom of the curtain 8 is wrapped around the outer surface of the rotating shaft 9, and the top end of the curtain 8 is fixed with the movable frame 13.

[0037] Through the cooperation between the curtain 8 and the rotating shaft 9, the curtain 8 can slide along the outer surface of the rotating shaft 9. At the same time, due to the cooperation between the curtain 8 and the movable frame 13, when the movable frame 13 slides along the outer surface of the fixed shaft 12, the tail end of the curtain 8 will be pulled upward, thereby automatically tensioning the curtain 8.

[0038] As shown in Figure 1 , 3 , the compression spring 14 is elastically supported between the notch 11 and the movable frame 13, and the outer surface of the curtain 8 is provided with warning symbols and slogans.

[0039] Through the design of the compression spring 14, the movable frame 13 has good elastic reset performance. At this time, since the compression spring 14 is in a compressed state, a spring force will be exerted on the movable frame 13, so as to drive the movable frame 13 to move the curtain 8 and tension the curtain 8.

[0040] Working principle:

[0041] Firstly, the staff can pull the movable rod 5 along the outer surface of the sliding groove 4 to move upward, when the movable rod 5 moves upward, the movable rod 5 is adjusted to the appropriate height, when the movable rod 5 stops moving, at this time the fixed frame 6 is clamped with the clamping groove 10 under the action of the torsion spring, the movable rod 5 is limited to move downward, at the same time, when the movable rod 5 moves, the fixed frame 6 and the positioning plate 7 will pull the curtain 8 upward, so that the curtain 8 slides along the outer surface of the rotating shaft 9, at this time the curtain 8 will pull the movable frame 13 to compress the compression spring 14, and through the elastic force of the compression spring 14, the movable frame 13 will be driven to tension the curtain 8.

[0042] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
