[0033] Example 1:

[0034] A fixing device for protective railings near openings, such as... Figures 1 to 5 As shown, a protective railing 3 is fixedly installed on the wall 1 around the edge opening 2, which is suitable for closing the edge opening 2 during construction to avoid safety hazards; the protective railing 3 is installed on the wall 1 through the fixing component 4, so that the protective railing 3 can move up and down and flip over, which facilitates construction.

[0035] like Figures 1 to 3 As shown, the fixing component 4 includes a pair of upper limit members 41, which are fixedly installed on the wall 1. The pair of upper limit members 41 are located on both sides of the top end of the guardrail 3. The upper limit member 41 has an L-shaped cross-section. One end of the upper limit member 41 is fixedly installed on the wall 1 by a fixing bolt 43, and the other end of the upper limit member 41 is located on one side of the guardrail 3 for installing the guardrail 3. Horizontally arranged pins 31 are fixedly installed on both sides of the top end of the guardrail 3. The side end face of the upper limit member 41 has a mounting groove 411. The pins 31 slide through the mounting groove 411, which is suitable for the guardrail 3 to move and rotate. The width of the mounting groove 411 is greater than the diameter of the pin 31 to facilitate movement. The end of the pin 31 is fixed. The circular plate is installed, with a diameter larger than the width of the mounting groove 411 to prevent it from falling off. The mounting groove 411 has a C-shaped structure, meaning that the main body of the mounting groove 411 is vertically oriented, while the two ends of the mounting groove 411 are horizontally oriented. This allows the pin 31 to move up and down and rotate within the mounting groove 411, and to be fixed at the top or bottom of the mounting groove 411, thereby driving the guardrail 3 to move up and down and flip. The top of the mounting groove 411 also has a limiting groove 4111, which is vertically oriented and connected to the horizontal structure at the top of the mounting groove 411. This allows the pin 31 to continue moving into the limiting groove 4111 when it moves to the top of the mounting groove 411, thus fixing the pin 31 and preventing it from slipping off.

[0036] like Figure 1 , Figure 4 As shown, the fixing component 4 also includes a lower limiting member 42, which is located at the lower end of the guardrail 3 and is 30 cm above the ground. One end of the lower limiting member 42 is rotatably mounted on the wall 1 by a fixing bolt 43, and the other end of the lower limiting member 42 has a fixing part 421 for fixing the guardrail 3. The fixing part 421 has a C-shaped cross-section and surrounds the outside of the guardrail 3 for fixing the guardrail 3. The lower limiting member 42 has a certain deformation capacity. When the guardrail 3 moves up and down, the lower limiting member 42 can rotate around the fixing bolt 43 to adapt to the position of the guardrail 3. When the guardrail 3 needs to be flipped, the lower limiting member 42 can be bent to make the fixing part 421 disengage from the guardrail 3.

[0037] As shown in Figure 5 The fixing bolt 43 comprises a bolt body 431 and a sleeve 432, the sleeve 432 is embedded in the wall body 1, the bolt body 431 is installed in the sleeve 432, and the inside of the sleeve 432 is provided with a thread corresponding to the thread of the bolt body 431.

[0038] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
