Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 , Figure 2 As shown, a lifting platform with detachable guardrail 3 includes a lifting platform 1, crossbeams 2 fixed on the four side walls of the lifting platform 1, and detachable guardrail 3 installed on the crossbeams 2. Figure 5 As shown, the side wall of the crossbeam 2 is provided with a positioning groove 201, and the lower end of the guardrail 3 is provided with a support block 301 that cooperates with the positioning groove 201. Each guardrail 3 is connected to the crossbeam 2 through at least two support blocks 301. In this application, as shown... Figure 3 As shown, the guardrail 3 along the length of the lifting platform 1 is connected to three support blocks 301, and the guardrail 3 along the width is connected to two support blocks 301. The positioning groove 201 is provided with a pin 4 for fixing the support block 301. The pin 4 can be slidably opened. After the pin 4 is opened, the guardrail 3 can be disassembled or rotated downwards by 180°.

[0026] The positioning groove 201 has an opening structure at the top and bottom. The side wall of the positioning groove 201 is provided with a shaft groove 202, which has an opening structure at the top. The side wall of the support block 301 is provided with a rotating shaft 303 that cooperates with the shaft groove 202. The rotating shaft 303 can be installed from the top of the shaft groove 202. After installation, the rotating shaft 303 is located in the middle position of the positioning groove 201. The support block 301 can rotate in the positioning groove 201. The support block 301 can drive the guardrail 3 to face up or down, and both facing up and down can be fixed by the pin 4.

[0027] like Figure 4 As shown, the support block 301 has a fixing groove 302 on its side wall, such as...
