[0027] like Figure 1-4 As shown, the utility model provides an assembled maintenance railing, including two support plates 6, a plurality of sleeves 4 are arranged between the two support plates 6, and a movable rod 5 is arranged between the two opposite sleeves 4, which passes through the sleeves 4 and is slidably connected to the penetrating part. Both ends of the movable rod 5 are fixedly connected with a limiting round block 10 that is slidably connected to the corresponding inner wall of the sleeve 4, and each of the sleeves 4 is limitedly connected to the corresponding support plate 6 through a positioning mechanism.

[0028] Preferably, the lower end surfaces of the two support plates 6 are fixedly connected to a base plate 7, and four mounting holes 9 are provided on the surface of the base plate 7 and are evenly distributed in a circle. The setting of the mounting holes 9 allows the base plate 7 to be fixedly connected to the ground by bolts.

[0029] Preferably, the positioning mechanism includes a limiting cylinder 2 that passes through the corresponding support plate 6 and is fixedly connected to the passing portion. A T-shaped groove 8 is provided at one end of the limiting cylinder 2. The setting of the T-shaped groove 8 can cooperate with the T-shaped slider 3, so that the sleeve 4 is limitedly connected to the limiting cylinder 2.

[0030] Preferably, a T-shaped slider 3 is slidably connected inside the T-shaped slide groove 8, one end of the T-shaped slider 3 is fixedly connected to one end of the corresponding sleeve 4, and an internal threaded cylinder 14 is provided inside the limiting cylinder 2, which passes through the limiting cylinder 2 and is slidably connected to the through-passing part. The setting of the internal threaded cylinder 14 can cooperate with the circular groove 15 to limit the T-shaped slider 3 in the T-shaped slide groove 8.

[0031] Preferably, the internal threaded barrel 14 is slidably connected to the circular groove 15 provided on the bottom surface of the corresponding T-shaped slider 3.

[0034] The specific working principle and usage of this utility model are as follows:

[0035] The utility model provides an assembled maintenance railing. When in use, the distance between the two sleeves 4 can be adjusted by the action of the movable rod 5 and the limiting circular block 10, so that the total length of the entire railing can be adjusted. Then, the bottom plate 7 is fixed to the ground by bolts under the action of the mounting hole 9, so that the entire device can be fixed and used. When the entire device needs to be transported, the threaded rod 11 is rotated by rotating the rotating handle 1, so that the internal threaded tube 14 is limited and slid under the action of the limiting slider 13 and the limiting slide groove 12, so that the internal threaded tube 14 is fixed and slid with the circular groove. 15 is separated, thereby releasing the limiting relationship between the T-shaped slide groove 8 and the T-shaped slider 3, and then the T-shaped slider 3 can be taken out of the T-shaped slide groove 8, and the sleeve 4 and the movable rod 5 can be disassembled, which can effectively reduce the overall area of ​​the entire device, which is convenient for staff to transport. During subsequent assembly, it is only necessary to slide the T-shaped slider 3 into the T-shaped slide groove 8, and the internal threaded tube 14 can be moved in the opposite direction by reversing the rotation handle 1, so that the internal threaded tube 14 can slide into the circular groove 15, so that the T-shaped slider 3 is limited in the T-shaped slide groove 8, and then the limiting assembly between the sleeve 4 and the support plate 6 is completed, which is more convenient.
