[0021] The railing 2 includes a rod body 21, a slide 22, a connecting rod 23, a rubber sleeve 24 and a spring 25. Slides 22 are installed at both ends of the rod body 21. One end of the connecting rod 23 is installed in the slide 22. The other end of the connecting rod 23 is inserted into the socket 3. A rubber sleeve 24 is slidably installed in the slide 22. A spring 25 is installed in the inner cavity of the slide 22. The spring 25 fits the side wall of the rubber sleeve 24. The rubber sleeve 24 and the spring 25 are both sleeved on the outside of the connecting rod 23. The rubber sleeve 24 can fit the outer wall of the guardrail post 1.

[0022] Because the railing 2 is fixed by the fixing ring 7 on the connecting rod 23 and the pressure ring 8 on the outer side of the bolt 6, the angle between the guardrail post 1 and the railing 2 can be adjusted by rotating the connecting rod 23, so that the device can be adjusted according to the specified enclosure position, thereby improving the applicability of the device;

[0023] At the same time, the setting of the rubber sleeve 24 can shield the connecting rod 23, and because the rubber sleeve 24 is in contact with the side wall of the guardrail post 1, it can prevent rainwater from entering the connecting groove 4 through the jack 3, and prevent the bolts 6 and the fixing ring 7 in the connecting groove 4 from rusting, thereby avoiding affecting the adjustment of the device.

[0024] Specifically, the inner cavity of the guardrail post 1 is provided with a connecting groove 4, which is connected to the socket 3. A threaded hole 5 is provided on the upper wall of the guardrail post 1. A bolt 6 is screwed into the threaded hole 5. The threaded hole 5 is connected to the connecting groove 4. A fixing ring 7 is installed at one end of the connecting rod 23 located in the socket 3. The fixing ring 7 is sleeved on the outside of the bolt 6. A pressure ring 8 is installed on the outer wall of the bolt 6 located in the connecting groove 4. The pressure ring 8 can be pressed above the fixing ring 7;

[0025] By rotating the bolt 6 , the pressure ring 8 can be driven to move downward so as to be pressed on top of the two fixing rings 7 , thereby fixing the angle of the railing 2 .

[0026] Specifically, a top ring 9 is installed in the connecting groove 4 . The top ring 9 is arranged on the outside of the bolt 6 . The top ring 9 can support the fixing ring 7 .

[0027] Specifically, a groove 10 is formed on the side wall of the guardrail post 1. The groove 10 is annular, and the rubber sleeve 24 can be inserted and installed in the groove 10.

[0028] By providing the groove 10 , the sealing performance of the connection between the connecting rod 23 and the guardrail post 1 can be further improved.

[0029] Specifically, an annular slot 11 is provided on the upper wall of the guardrail post 1, into which one end of a connecting tube 12 is inserted, and a decorative sphere 13 is installed at the other end of the connecting tube 12, which can be sleeved on the outer side of the bolt 6;

[0030] The bolt 6 can be protected by the connecting tube 12 to prevent rainwater from coming into contact with the bolt 6 and causing the bolt 6 to rust.

[0031] Specifically, the outer wall of the connecting tube 12 is sleeved with a sealing ring 14, which can be inserted into the annular slot 11;

[0032] The sealing ring 14 can improve the sealing performance of the connection between the connecting tube 12 and the annular slot 11, and further prevent the entry of rainwater.

[0033] Working principle: When the angle of the guardrail needs to be adjusted, the connecting tube 12 can be removed first, and then the bolt 6 can be screwed upward to move the pressure ring 8 upward to release the lock on the fixing ring 7. At this time, the staff can adjust the angle between the guardrail 2 and the guardrail post 1 by rotating the guardrail 2. After the adjustment is completed, the bolt 6 is tightened, and the fixing ring 7 is clamped through the cooperation of the pressure ring 8 and the top ring 9 to fix the guardrail 2. After the adjustment is completed, the connecting tube 12 needs to be inserted back into the annular slot 11 so that the connecting tube 12 can protect the bolt 6.

[0034] At the same time, under the action of the spring 25, the rubber sleeve 24 can be firmly inserted into the groove 10, ensuring the sealing of the connection between the connecting rod 23 and the guardrail post 1, and preventing the connection from contacting with external rainwater to cause rust.
