[0026] Furthermore, the corners of the friction lining 2 are provided with guide slopes 21 for guiding the friction lining 2 to be embedded in the installation groove 11;

[0027] Specifically, by providing a guide slope 21 at the corner of the friction lining 2, the friction resistance during assembly can be effectively reduced, making it easier for the friction lining 2 to be embedded in the mounting groove 11. This also helps protect the surface of the friction lining 2 and the avoidance groove 33, avoiding damage during assembly.

[0028] Furthermore, chamfered surfaces 22 for guiding the friction lining 2 to be embedded in the mounting groove 11 are provided at the lower edges of both sides of the friction lining 2, and a plurality of anti-slip protrusions 23 are provided on both sides of the friction lining 2;

[0029] Specifically, the design of the chamfered surface 22 helps to reduce the friction between the friction lining 2 and the mounting groove 11, so that the friction lining 2 can slide into the mounting groove 11 more smoothly. The anti-slip protrusion 23 is interference fit with the mounting groove 11 to prevent the friction lining 2 from shifting left and right.

[0030] Furthermore, both ends of the friction lining 2 are plugged and matched with the guide rail bracket 1 through a horizontal plug-in structure 3, and the horizontal plug-in structure 3 includes plug-in slots 31 located on both sides of the ends of the installation slot 11 and plug-in strips 32 located on both sides of the ends of the friction lining 2, and the plug-in slot 31 is provided with a side away from the middle of the guide rail bracket 1.

[0032] Furthermore, one end of the plug-in strip 32 away from the middle of the friction lining 2 is provided with a first slope surface 321 for guiding the plug-in strip 32 to be embedded in the avoidance groove 33;

[0033] Specifically, the first slope surface 321 can reduce the resistance of the plug-in strip 32 when it is inserted into the avoidance groove 33, thereby avoiding damage during the assembly process.

[0034] Furthermore, the middle part of the friction lining 2 is plugged and matched with the guide rail bracket 1 through a vertical plug-in structure 4, so that the friction lining 2 is tightly attached to the guide rail bracket 1, and the vertical plug-in structure 4 includes a reserved countersunk groove 41 located on the front of the middle part of the installation groove 11 and a positive block 42 located on the bottom of the middle part of the friction lining 2, and the positive block 42 is plugged and matched with the reserved countersunk groove 41;

[0035] Specifically, when the alignment block 42 is interference-fitted with the reserved countersunk groove 41 , the alignment block 42 can be prevented from moving up and down, and the deformation capacity of the friction lining 2 can be limited, thereby improving the fit between the friction lining 2 and the guide rail bracket 1 .

[0036] Furthermore, both sides of the end of the aligning block 42 away from the friction lining 2 are provided with a second slope surface 421 for guiding the aligning block 42 to be embedded in the reserved countersunk groove 41;
