[0012] Preferably, the guide rubber blocks are made of fireproof rubber, and two groups of guide rubber blocks are provided.

[0013] Preferably, the guide rubber blocks are distributed at equal intervals longitudinally with respect to the top side of the slide rail.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The device can prevent the position of the walking wheel from being offset, improve the stability of the walking wheel, and prevent the walking wheel from shaking during walking.

[0016] (2) The device sets a first adsorption anti-deflection block on the outer wall of the walking wheel body and a second adsorption anti-deflection block on the top of the slide rail. The second adsorption anti-deflection block corresponds to the first adsorption anti-deflection block in position. At the same time, the second adsorption anti-deflection block is magnetically adsorbed to the first adsorption anti-deflection block, so that a certain suction force can be used to improve the tightness of the connection between the walking wheel body and the slide rail, thereby preventing the walking wheel body from shaking left and right and improving the stability of the walking wheel body during movement.

[0017] (3) The device sets guide rubber blocks on both sides of the top of the slide rail. The guide rubber blocks are set horizontally, so that when the walking wheel body moves left and right, the friction can be increased by contact with the guide rubber blocks, thereby avoiding excessive left and right shaking of the walking wheel body.
