[0010] Preferably, a mushroom protrusion is fixedly connected to the outer surface of the rubber ring, and the head diameter of the mushroom protrusion is half of the stem diameter.

[0011] Compared with the prior art, the utility model has the advantages and positive effects that:

[0012] 1. In this utility model, the rubber ring is used to buffer the wheel and the track to reduce impact and noise. The elastic ring can adjust the contact area with the track in real time through its elastic deformation, thereby reducing the risk of derailment caused by lateral force and increasing guiding stability.

[0013] 2. In this utility model, the mushroom-shaped protrusions form a biomimetic coupling structure tread surface, which enhances track adhesion through intermolecular forces, making the operation more stable. The side limiting plate restricts the position of the elastic ring and rubber ring to prevent separation, and at the same time, it can confine the track between the wheel body and the side limiting plate, further reducing the risk of derailment. The limiting plate facilitates installation and use, and during installation, the through hole and threaded hole can be aligned to facilitate the installation of fastening bolts. The extension sleeve increases the connection area with the fastening bolts, thereby increasing the connection strength and ensuring the stability of use. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides an anti-derailment guide rail wheel tread structure, including a wheel body 1, an installation hole 8 in the middle of the wheel body 1, reinforcing ribs 6 fixedly connected to both sides of the wheel body 1, a rubber ring 2 fixedly connected to the outer surface of the wheel body 1, an elastic ring 5 fixedly connected to one end of the outer surface of the rubber ring 2, and a side limiting plate 3 provided on one side of the wheel body 1.
