[0025] Specifically, the friction lining 2 can replace the friction between the guide rail bracket 1 and the chain, avoiding the guide rail bracket 1 from being damaged, and once the friction lining 2 is worn, it can be replaced at any time, thereby extending the life of the equipment.

[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 mounting groove 11;

[0027] Specifically, the guide slope 21 can guide the friction lining 2 to correctly align with the insertion groove 31, the first avoidance groove 33 or the second avoidance groove 41 on the guide rail bracket 1 during the installation process to ensure precise matching.

[0028] Furthermore, both ends of the friction lining 2 are plugged with the guide rail bracket 1 through a first plug-in structure 3, the first plug-in structure 3 includes plug-in slots 31 located at both sides of the ends of the mounting slot 11 and first plug-in strips 32 located at both sides of the ends of the friction lining 2, a first avoidance slot 33 is provided on one side of the plug-in slot 31 away from the middle of the guide rail bracket 1, and the first plug-in strip 32 is limited in the first avoidance slot 33;

[0029] Specifically, the two first plug-in strips 32 are respectively embedded in the two first avoidance grooves 33 , which can provide a limiting effect for the friction lining 2 , so that the friction lining 2 can fit in the installation groove 11 .

[0030] Furthermore, one end of the first plug-in strip 32 away from the middle of the friction lining 2 is provided with a first slope surface 321 for guiding the first plug-in strip 32 to be embedded in the first avoidance groove 33;

[0031] Specifically, the first slope surface 321 can be used as a guide surface to help the first plug-in strip 32 to be more easily inserted into the corresponding first avoidance groove 33 or pass through the second avoidance groove 41 to achieve accurate positioning.

[0032] Further, the middle part of the friction lining 2 is plugged with the guide rail bracket 1 through the second plug-in structure 4, so that the friction lining 2 is tightly attached to the guide rail bracket 1, and the second plug-in structure 4 includes a second avoidance groove 41 located on both sides of the middle part of the installation groove 11 and a second plug-in strip 42 located on both sides of the middle part of the friction lining 2, both ends of the second avoidance groove 41 are connected to the adjacent plug-in groove 31, and the second plug-in strip 42 is limited in the second avoidance groove 41;

[0033] Specifically, the second plug-in strip 42 is embedded in the second avoidance groove 41 , which helps to maintain the close contact between the middle of the friction lining 2 and the guide rail bracket 1 to prevent the middle of the friction lining 2 from bulging.

[0037] Specifically, the bending portion 22 is pulled to bend the friction lining 2 to a certain extent, and this action helps to shorten the span of the friction lining 2 so that the first plug-in strip 32 can be inserted into the first avoidance groove 33 .

[0038] Working principle: When in use, align one end of the friction lining 2 with the plug-in groove 31 and insert it, so that the first plug-in strip 32 is aligned with the second avoidance groove 41 and inserted. After one end of the friction lining 2 passes through the second avoidance groove 41, one of the first plug-in strips 32 is aligned with the first avoidance groove 33 and plugged, and the second plug-in strip 42 is embedded in the second avoidance groove 41. The bending part 22 is bent, so that the other first plug-in strip 32 is aligned with the first avoidance groove 33 and inserted, which can ensure that the guide rail bracket 1 and the friction lining 2 are in close contact.
