[0034] A second bar frame 34 is arranged on the top of the first bar frame 32, and the second bar frames 34 are arranged at equal intervals on one side of the second main rod 2. The first cross bar 31 extends into the first bar frame 32 and matches the first bar frame 32. The second cross bar 33 extends into the second bar frame 34 and matches the second bar frame 34. A lifting bracket 35 is arranged on the rear side of the first bar frame 32. The lifting bracket 35 is movably connected to the rear sides of the first bar frame 32 and the second bar frame 34 respectively. A first guide rod 36 is fixedly connected to one side of the second main rod 2.

[0035] The first bar frame 32 and the second bar frame 34 are fixedly connected to one side with an auxiliary plate 37, and the first guide rod 36 is provided with a first positioning hole 38. The top of the second bar frame 34 at the top is fixedly connected to a U-shaped plate 39, and a first threaded rod 391 is arranged inside the U-shaped plate 39. The first threaded rod 391 extends out of the outside of the U-shaped plate 39 and is threadedly connected to the U-shaped plate 39. When in use, the first cross bar 31 and the second cross bar 33 are respectively inserted into the first bar frame 32 and the second bar frame 34, so as to form a lateral protection effect. Since the first cross bar 31 and the second cross bar 33 can be flexibly moved inside the first bar frame 32 and the second bar frame 34, the spacing between the first main rod 1 and the second main rod 2 can be adjusted. Secondly, due to the addition of the lifting bracket 35, the protection width of the first bar frame 32 and the second bar frame 34 arranged up and down can be controlled by controlling the upper and lower movements of the second bar frame 34 at the top, so as to be flexibly adjusted to meet different protection needs.

[0038] The second main rod 2 is fixedly connected to a surrounding plate 4 on the outside, and a connecting plate 5 is fixedly connected to one side of the first main rod 1. A docking assembly 6 is arranged between the surrounding plate 4 and the connecting plate 5. The docking assembly 6 can be used for splicing between the adjacent first main rod 1 and the second main rod 2. The docking assembly 6 includes a sliding seat 61, which is arranged on one side of the surrounding plate 4. One side of the sliding seat 61 extends into the interior of the surrounding plate 4 and is slidably connected to the surrounding plate 4.

The mounting tube 63 extends between the two circle plates 62, and the mounting tube 63 contacts the two circle plates 62 respectively. Two insertion rods 64 are slidably connected inside the mounting tube 63. The insertion rod 64 extends out of the mounting tube 63, and the two insertion rods 64 extend into the interior of the two circle plates 62 respectively, and the insertion rod 64 matches the circle plates 62. A spring 65 is fixedly connected to the insertion rod 64, and the spring 65 is fixedly connected to the interior of the mounting tube 63. The spring 65 has an elastic force on the insertion rod 64.

[0039] In actual operation, when the device is used, the first cross bar 31 and the second cross bar 33 on one side of the first main rod 1 can be respectively inserted into the first bar frame 32 and the second bar frame 34 on one side of the second main rod 2, and can be combined into a separate guardrail individual by splicing in the above steps. After splicing, if it is necessary to adjust the distance between the first main rod 1 and the second main rod 2, the first main rod 1 and the second main rod 2 can be directly pushed and pulled toward or away from each other. When adjusted to a suitable range, a corresponding second positioning hole 396 within this range is taken, and the second positioning hole 396 is caused to stay at the corresponding position of the positioning rod 395, and then the second threaded rod 397 is rotated. The second threaded rod 397 drives the movable plate 394 to move, and the movable plate 394 drives the positioning rod 395 to move to insert into the second positioning hole 396. Then, the first insertion rod 64 cannot continue to move inside the first bar frame 32, and the adjustment is completed.

[0040] The lifting bracket 35 is an existing structure, so it will not be described in detail here. When the lateral protection width needs to be adjusted, due to the addition of the lifting bracket 35, the top second bar frame 34 is pushed and pulled up and down. Due to the addition of the lifting bracket 35, all the second bar frames 34 are synchronously vertically displaced at this time to adjust the lateral protection width. After the adjustment, similar to the above positioning rod 395 inserted into the second positioning hole 396, the first positioning hole 38 within the appropriate range is selected, and after the first threaded rod 391 is rotated, the first threaded rod 391 is inserted into the selected first positioning hole 38. At this time, the first bar frame 32 maintains the adjusted height. The above entire adjustment process is simple and convenient, and can flexibly respond to the adjustment and use needs of different scenarios;

[0041] Finally, when multiple guardrails are needed to be used for splicing and assembling the enclosure, the insertion rod 64 can be pushed into the installation tube 63 first, and then the installation tube 63 is placed between the two ring plates 62 on one side of the sliding seat 61. Due to the elastic force of the spring 65, the insertion rod 64 is pushed into the ring plate 62. At this time, the splicing and assembly between the first main rod 1 and the second main rod 2 is completed. Similarly, when disassembly is required, the installation tube 63 can be directly taken out from between the two ring plates 62. The loading and unloading process is simple and convenient, and easy to operate. After connecting in the above manner, since the sliding seat 61 can move along the groove opened on the surrounding plate 4, it is equivalent to the assembled first main rod 1 being able to swing with the second main rod 2 on the inner side of the surrounding plate 4 as the axis, so as to achieve enclosure at different angles. After the enclosure, due to the existence of the connection relationship, the overall structure is more solid and has greater stability.

[0042] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
