[0028] See also Figure 1-Figure 4 As shown, the utility model provides an embodiment of a foldable lock-stabilized PVC guardrail, comprising a first guardrail section 1 made of PVC and two sets of second guardrail sections 101, the two sets of second guardrail sections 101 are rotatably mounted on the lower surface of the first guardrail section 1, a connecting ring 102 and a receiving groove 103 are fixedly mounted on the lower surface of the first guardrail section 1, a locking assembly 2 is rotatably mounted in the connecting ring 102, the locking assembly 2 can be rotatably received in the receiving groove 103, an arc-shaped sliding groove 104 and a fitting groove 105 are provided on the upper surface of the second guardrail section 101, The second section of the guardrail 101 can drive the fitting groove 105 to fit on the outer surface of the connecting ring 102, and the locking assembly 2 can be rotated from the storage groove 103 into the two sets of arc-shaped slide grooves 104. The first section of the guardrail 1 is fixedly installed with fastening plates 3 at both ends, and a circular groove 303 is opened at the lower end of the fastening plate 3. The upper half of the locking assembly 2 is rotatably installed in the circular groove 303, and a guide groove 302 is opened in the circular groove 303 of the fastening plate 3. A snap-on assembly 4 is slidably installed in the guide groove 302, and the snap-on assembly 4 can be snap-fitted and installed on the outer surface of the locking assembly 2.

[0029] The locking assembly 2 includes a rotating rod 204, which is rotatably installed in the connecting ring 102. Both ends of the rotating rod 204 are fixedly installed with a control dial 201. The control dial 201 is rotatably located at one end of the first section of the guardrail 1, and the upper half is rotatably located in the circular groove 303.

[0030] An arc disk 203 is fixedly installed on the outer surface of the control dial 201 . The control dial 201 can drive the arc disk 203 fixedly installed on the outer surface of the rotating rod 204 to rotate and be stored in the storage groove 103 , and can also rotate and fit into the two sets of arc sliding grooves 104 .

[0031] like Figure 5As shown, the clamping assembly 4 includes a guide block 401, which is slidably installed in the guide groove 302. The guide block 401 can be clamped and installed in the clamping groove 202.
