It can be understood that the provision of the guard rail 117 prevents the influence of the external environment on the upper rail 11, such as the infiltration of dust and liquid droplets, and ensures the stability of the operation process of the upper rail 11.

Referring to fig. 1 to 12, in an embodiment of the present invention, the door frame 10 further includes two upright frames 15 disposed oppositely along the sliding direction, a damping groove 153 is disposed in the upright frame 15, the number of the damping groove 153 corresponds to the number of the movable door 30, and a damping block 151 made of elastic material is disposed in the damping groove 153. Due to the arrangement, in the process of pushing and pulling the movable door body 30, the impact possibly generated on the opposite frame 15 is buffered and absorbed by the shock absorption block 151 made of the elastic material, so that the stability of the process of pushing and pulling the movable door body 30 is protected, and the noise possibly generated by collision between the movable door body 30 and the door frame 10 is reduced.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
