[0023] In a specific embodiment of the utility model, the mounting seat 1 is installed at the bottom of the linear door by bolts. When the height of the roller 2 needs to be adjusted, the limit assembly on the screw 15 is released, the screw 15 at the corresponding position is rotated, and the movable cavity 14 limits the movable block 13, so that the movable block 13 moves along the slide groove 17. The movable block 13 drives the fixed plate 4 to move the connecting block 3, thereby changing the height of the corresponding roller 2; when the walking mechanism moves, the roller 2 can drive the fixed plate 4 to move, and the fixed plate 4 slides along the connecting rod 6 and squeezes the spiral spring 5. The reaction force of the spiral spring 5 can buffer the impact force, reduce the amplitude of vibration, and make the linear door move more smoothly. The walking mechanism allows the height of the rollers 2 on both sides of the mounting seat 1 to be adjusted according to the use environment, so that the rollers 2 maintain good contact with the ground, and can play a good supporting effect on the linear door; through the cooperation between the fixed plate 4, the connecting rod 6, the spiral spring 5 and the fixed plate 4, the walking mechanism has a good shock absorption effect, so that the linear door moves more smoothly and improves its stability.

[0024] Specifically, the limiting assembly includes a base plate 10, a block 16 is fixedly connected to the top of one end of the base plate 10, a slot 12 is provided at the bottom of the screw rod 15, the slot 12 and the block 16 are adapted to each other, a screw 11 is rotatably connected to the inside of one side of the base plate 10, and the screw 11 is threadedly connected to the mounting seat 1.

[0025] In this embodiment: rotate the screw 11, remove the screw 11 from the bottom of the mounting base 1, move the bottom plate 10 downward, and the bottom plate 10 drives the block 16 to move. When the block 16 is moved out of the slot 12, the limit on the screw 15 can be released. At this time, the screw 15 can be driven to rotate by the rotating block 9, so that the height of the corresponding roller 2 can be changed.

[0026] Specifically, there are two connecting rods 6 , and the two connecting rods 6 are symmetrically distributed on the fixing plate 4 .

[0027] In this embodiment, two symmetrically distributed connecting rods 6 are provided to make the force on the fixed plate 4 more uniform, thereby improving the structural stability of the walking mechanism.

[0028] Specifically, both sides of the mounting seat 1 are fixedly connected with fixing blocks 7 , and the fixing blocks 7 are fixedly connected with push plates 8 .

[0029] In this embodiment, the push plate 8 is located at one side of the roller 2. When the walking mechanism moves, the push plate 8 can push away stones and other debris on the ground, reduce obstacles on the road surface, and make the roller 2 move more smoothly.

[0030] Specifically, the push plate 8 is composed of two inclined plates.

[0031] In this embodiment, by providing a push plate 8 composed of two inclined plates, obstacles such as stones on the ground can be pushed away from the path of the roller 2, thereby achieving a better cleaning effect.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
