[0029] Embodiment 1

[0030] See attached Figure 1-Figure 5 As shown, an embodiment of the utility model is a bendable PVC safety guardrail, including a first PVC guardrail body 2, the bottom end of the leg of the first PVC guardrail body 2 is fixedly connected to a base plate 1, and the upper part of the first PVC guardrail body 2 is rotatably mounted with a second PVC guardrail body 4 through a hinge 3.

[0031] A first support and limit component is installed at one end of the top of the base plate 1, and the first support and limit component is connected to the second PVC guardrail body 4 in the upright state. A second support and limit component is installed at the other end of the top of the base plate 1, and the second support and limit component is connected to the second PVC guardrail body 4 in the bent state.

[0032] Through the above technical scheme, the first supporting and limiting component increases the overall strength of the PVC safety guardrail, ensures the stability of the PVC safety guardrail in normal height usage state, and prevents the second PVC guardrail body 4 from shaking due to wind or accidental collision after bending through the second supporting and limiting component, thereby further increasing the stability of the PVC safety guardrail after bending.

[0033] Embodiment 2 is an improvement of embodiment 1:

[0034] The first supporting and limiting component includes a telescopic rod 5 and a clamping bolt 6; the telescopic rod 5 includes an outer rod and an inner rod movably inserted at one end of the outer rod, the bottom of the outer rod is fixedly connected to the base plate 1, and a through hole 51 is provided at the upper end of the inner rod; a first thread groove 41 is provided on one side of the second PVC guardrail body 4, and one end of the clamping bolt 6 passes through the through hole 51 and is threadedly installed inside the first thread groove 41.

[0035] When the second PVC guardrail body 4 is in an upright state, the telescopic rod 5 is connected and fixed to the second PVC guardrail body 4 by using the tightening bolt 6, and the second PVC guardrail body 4 is limited to prevent the second PVC guardrail body 4 from bending. In addition, the telescopic rod 5 can achieve a storage effect to avoid the exposure of the limiting rod and affect the use height of the PVC safety guardrail after bending.

[0036] The second supporting and limiting component includes a supporting column 7, which is fixedly mounted on the base plate 1. A second thread groove 71 is provided at the top of the supporting column 7. A screw rod 8 is installed on the internal thread of the second thread groove 71. A push rod 9 is integrally formed on the upper end of the screw rod 8. A slot 42 is provided on the top of the second PVC guardrail body 4, and the upper end of the push rod 9 is inserted into the inside of the slot 42.

[0037] When the second PVC guardrail body 4 is in a bent state, the screw rod 8 is rotated to make the top rod 9 abut against the inside of the slot 42 at the top of the second PVC guardrail body 4, thereby achieving the effect of limiting the second PVC guardrail body 4, preventing the bent second PVC guardrail body 4 from shaking due to wind or accidental collision, and further increasing the stability of the bent PVC safety guardrail. In addition, the top support of the top rod 9 is adjusted by the screw rod 8, which is convenient for operation.

[0038] A non-slip handle 91 is fixedly mounted on the top rod 9, which is convenient for adjusting the screw rod 8 and is helpful for adjusting and using the PVC safety guardrail.

[0039] The screw rod 8 is made of stainless steel, which is not easy to be damaged by rust and has a long service life, thus reducing the later maintenance cost of the PVC safety guardrail.

[0040] The clamping bolt 6 is a handle bolt, through which the bending adjustment of the PVC safety guardrail can be performed directly and manually without the need for external tools, thereby increasing the practicality of the bendable PVC safety guardrail.

[0041] The working principle of the utility model: when the PVC safety guardrail is in normal use, the second PVC guardrail body 4 is in an upright state, and the inner rod upper end of the telescopic rod 5 is fixedly connected to one side of the second PVC guardrail body 4 by a tightening bolt 6, so as to avoid bending of the second PVC guardrail body 4, increase the overall use strength of the PVC safety guardrail, and ensure the stability of the PVC safety guardrail in normal height use state.

[0042] When the PVC safety guardrail is in a bent state, the hinge 3 can be used to bend and flip the second PVC guardrail body 4 on the first PVC guardrail body 2. The second PVC guardrail body 4 after bending and flipping is supported and limited by the top rod 9 to prevent the bent second PVC guardrail body 4 from being shaken by wind or accidental collision, thereby further increasing the stability of the bent PVC safety guardrail.

[0043] The above different embodiments can be combined, replaced and used in conjunction with each other.

[0044] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
