DETAILED DESCRIPTION

[0020] 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.

[0021] Example 1

[0022] See also Figure 1-5 The utility model provides the following technical solutions: a fence structure for elevator maintenance, including a main fence 6, which is placed on the outside of the elevator body 1, and a warning poster body 7 is arranged on the side of the main fence 6, and the warning poster body 7 is fixedly connected to the main fence 6 by a warning poster fixing mechanism 5, a first side fence 2 is arranged on one side of the main fence 6, and the main fence 6 is rotatably connected to the first side fence 2 by a rotating shaft 3, a second side fence 8 is arranged on the other side of the main fence 6, and the main fence 6 is rotatably connected to the second side fence 8 by a rotating shaft 3, and universal wheels 4 are arranged at the lower ends of the first side fence 2, the main fence 6 and the second side fence 8, and the first side fence 2, the main fence 6 and the second side fence 8 are fixedly connected by a fence fixing mechanism 9.

[0023] Specifically, the fence fixing mechanism 9 includes a turning handle 91, a mounting seat 92, a pull ring 94, a screw 95, a slide plate 96 and a fixing rod 97. The upper ends of the first side fence 2, the main fence 6 and the second side fence 8 are provided with a mounting seat 92, the upper end of the mounting seat 92 is provided with a pull ring 94, the internal rotation connection of the mounting seat 92 is provided with a screw 95, the surface of the screw 95 is threadedly connected with a slide plate 96, the lower end of the side of the slide plate 96 is provided with a fixing rod 97, and the other end of a group of screws 95 is provided with a turning handle 91.

[0024] By adopting the above technical solution, when the fence structure needs to be folded and stored, first fold the first side fence 2, the main fence 6 and the second side fence 8 into a long strip, then clamp the mounting seat 92 at the upper end of the first side fence 2, the main fence 6 and the second side fence 8, turn the handle 91, and the rotation of the handle 91 drives the screw 95 to rotate. The rotation of the screw 95 drives the two groups of slides 96 to approach each other. The two groups of slides 96 approach each other and drive the two groups of fixing rods 97 to approach each other, thereby limiting and fixing the first side fence 2, the main fence 6 and the second side fence 8 after folding. At this time, the fence structure can be conveniently stored.

[0025] Specifically, the fence fixing mechanism 9 also includes a rotating block 93 and a rotating groove 98. The rotating block 93 is arranged on the surface of the central position of the screw 95, and the rotating groove 98 corresponding to the rotating block 93 is opened inside the mounting seat 92.

[0026] By adopting the above technical solution, when the screw rod 95 rotates, it will drive the rotating block 93 to rotate inside the rotating groove 98, thereby avoiding the problem of misalignment caused by the rotation of the screw rod 95.

[0027] Specifically, the other end surfaces of the two sets of screw rods 95 are provided with two sets of external threads in opposite directions.

[0028] By adopting the above technical solution, the arrangement of the structure can enable the rotation of the screw rod 95 to drive the two sets of slide plates 96 to move closer to or away from each other.

[0029] When the present embodiment is in use and the fence structure needs to be folded and stored, the first side fence 2, the main fence 6 and the second side fence 8 are first folded into a long strip, and then the mounting seat 92 is clamped on the upper ends of the first side fence 2, the main fence 6 and the second side fence 8, and the turning handle 91 is turned. The turning handle 91 drives the screw 95 to rotate, and the screw 95 drives the two groups of slides 96 to approach each other. The two groups of slides 96 approach each other and drive the two groups of fixing rods 97 to approach each other, thereby limiting and fixing the first side fence 2, the main fence 6 and the second side fence 8 after folding. At this time, the fence structure can be conveniently stored. When the screw 95 rotates, it drives the rotating block 93 to rotate inside the rotating groove 98, thereby avoiding the problem of misalignment caused by the rotation of the screw 95.

[0030] Example 2

[0031] The difference between this embodiment and the first embodiment is that the warning poster fixing mechanism 5 includes a fixing plate 51, a limiting plate 52, a spring 53, a pull rod 54, a handle 55 and a fixing block 56. The fixing block 56 is arranged at the upper end and the lower end corner of the main fence 6. The limiting plate 52 is arranged inside the fixing block 56. The fixing plate 51 is arranged at the lower end of the limiting plate 52. The pull rod 54 is arranged at the upper end of the limiting plate 52. The surface of the pull rod 54 is sleeved with a spring 53.

[0032] By adopting the above technical solution, first pull the pull rod 54, the pull rod 54 pulls the limit plate 52 and the fixed plate 51, and drives the spring 53 to compress, and then place the warning poster body 7 on the side of the main fence 6, release the pull rod 54, the spring 53 rebounds, thereby driving the fixed plate 51 to clamp the warning poster, so as to achieve the fixing of the warning poster.

[0033] Specifically, a handle 55 is provided at the upper end of the pull rod 54, a limiting groove corresponding to the limiting plate 52 is provided inside the fixing block 56, and the spring 53 is located inside the limiting groove.

[0034] By adopting the above technical solution, the arrangement of the structure can facilitate pulling the pull rod 54.

[0035] When this embodiment is in use, the handle 55 is pulled, the handle 55 pulls the pull rod 54, the pull rod 54 pulls the limit plate 52 and the fixed plate 51, and drives the spring 53 to compress, and then the warning poster body 7 is placed on the side of the main fence 6, the pull rod 54 is released, and the spring 53 rebounds, thereby driving the fixed plate 51 to clamp the warning poster, so as to achieve the fixation of the warning poster.

[0036] Working principle and use process of the utility model: When the utility model is used, when the fence structure needs to be folded and stored, firstly, the first side fence 2, the main fence 6 and the second side fence 8 are folded into a long strip, and then the mounting seat 92 is clamped at the upper end of the first side fence 2, the main fence 6 and the second side fence 8, and the turning handle 91 is turned, and the turning handle 91 drives the screw 95 to rotate, and the screw 95 drives the two sets of slide plates 96 to approach each other, and the two sets of slide plates 96 are approached to drive the two sets of fixing rods 97 to approach each other, so as to fold the first side fence 2, the main fence 6 and the second side fence 8. After the fence 8 is folded, the limiting and fixing work can be carried out, and the fence structure can be conveniently stored at this time. When the screw 95 rotates, it will drive the rotating block 93 to rotate inside the rotating groove 98, thereby avoiding the problem of misalignment caused by the rotation of the screw 95; pull the handle 55, the handle 55 pulls the pull rod 54, the pull rod 54 pulls the limiting plate 52 and the fixed plate 51, and drives the spring 53 to compress, and then place the warning poster body 7 on the side of the main fence 6, release the pull rod 54, the spring 53 rebounds, thereby driving the fixed plate 51 to clamp the warning poster, so as to realize the fixing of the warning poster.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
