[0026] Example

[0027] Reference Figure 1 As shown, this embodiment provides a movable guardrail, including a unit guardrail 1 and a fixing assembly 2. The unit guardrail 1 includes a support leg portion 11 and a guardrail portion 12, and the support leg portion 11 is connected to the bottom of the guardrail portion 12 and placed on the ground. The fixing assembly 2 includes an internal frame, an external shell 21 and a fixing member 22; the internal frame is connected to the end of the guardrail portion 12. The external shell 21 covers the two side surfaces of the internal frame and is connected to the internal frame. The two edges of the external shell 21 are respectively connected to the fixing member 22. The fixing member 22 is fixedly connected to the ground. In this embodiment, the guardrail may include one unit guardrail 1, or may include multiple unit guardrails 1. When the number of unit guardrails 1 is one, refer to Figure 1 As shown, fixing components 2 are respectively provided at both ends of the unit guardrail 1. When there are multiple unit guardrails 1, two adjacent unit guardrails 1 can be connected by the fixing components 2 to form an integrated guardrail.

[0028] The mobile guardrail provided in this embodiment only needs to disassemble the connection nodes between the fixing member 22 on the fixing assembly 2 and the ground during installation and disassembly, and fewer connection nodes need to be disassembled and assembled. When transferring, the guardrail unit is moved in blocks, making the disassembly and assembly process more convenient. After installation, the unit guardrail 1 is supported by the support leg portion 11 and fixed by the fixing assembly 2, which can also ensure the overall stability during the protection process.

[0029] Specifically, refer to Figure 2 As shown, the internal frame includes a connecting crossbar 23 and an end panel 24, and the connecting crossbar 23 is connected to the end panel 24 by bolts and penetrates the end panel 24. The end panel 24 is connected to the external shell 21; the guardrail part 12 includes a first vertical rod 13 and a first crossbar 14; the first vertical rod 13 and the first crossbar 14 are arranged crosswise and connected; the connecting crossbar 23 and the first crossbar 14 are connected by a bolt after being plugged in. The use of a bolt facilitates the connection of the guardrail part 12 with the internal frame, thereby facilitating the assembly of the mobile guardrail.

[0030] Specifically, the edge of the external shell 21 is bent in a direction away from the internal frame to form a first connection portion 25. The fixing member 22 includes a second connection portion 26 and a third connection portion located at the edge of the second connection portion 26; the second connection portion 26 is connected to the ground through an expansion bolt, and the third connection portion is bent to fit with the first connection portion 25 and bolted to the first connection portion 25. By bending the first connection portion 25 and the third connection portion, the area of ​​the bottom of the fixing component 2 is expanded, so that the fixing component 2 is more stable after being connected to the ground. Separating the external shell 21 from the fixing member 22 is more convenient to prepare and easier to maintain the balance on both sides of the fixing component 2 than integral molding. In other embodiments, the external shell 21 and the fixing member 22 can also be integrally molded.

[0031] Specifically, fixing members 22 are respectively provided on both sides of the internal frame, and a supporting base plate 27 is connected between the two fixing members 22 , and the supporting base plate 27 is placed on the ground.

[0032] Specifically, refer to Figure 3 As shown, the support leg portion 11 includes a first support plate 15 and a second support plate 16; the first support plate 15 includes a first plate body 17 and a second plate body 18 which are perpendicular to each other; the first plate body 17 is bolted to the side of the first vertical pole 13, the second plate body 18 is abutted against the bottom of the first vertical pole 13, and the length of the second plate body 18 is greater than the width of the first vertical pole 13; the second support plate 16 includes a bottom support plate 19, and a side support plate 20 formed by bending the two sides of the bottom support plate 19; the spacing between the two side support plates 20 gradually increases from high to low, and the two side support plates 20 are bolted to the first vertical pole 13 respectively. The second support plate 16 increases the contact area with the ground, so that the unit guardrail 1 is more stable when placed. By adding the first support plate 15 between the first vertical pole 13 and the second support plate 16, the stability of the unit guardrail 1 can be further improved.

[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
