Summary of the invention: order of the present utility model be to provide a kind of simple in structure, need not lay track, convenient for installation and maintenance on the ground, and the trackless sliding door that not influenced by pavement quality.

The utility model is achieved through the following technical solutions: a kind of trackless sliding door is made up of the door pillar that is fixed in ground and a pair of guide roller, door leaf, door lifter and transmission mechanism, described door lifter is connected with described door leaf by transmission mechanism, it is characterized in that: the bottom at the lower door frame of described door leaf is provided with " () " chute, described door leaf is sleeved on the described a pair of guide roller by described " () " chute, and can move with respect to this guide roller.

The utility model compared with prior art has following advantage:

1. because this sliding door does not have track, therefore be not subjected to the influence of ground quality;

2. on the support of the guide roller of this sliding door guiding mechanism is arranged, both guaranteed that transmission mechanism reaches optimum state, guarantee the verticality up and down of door again.

3. owing at the opposite side of door heel post is installed, guide strip is arranged above the heel post, the bottom is provided with gripper shoe, has both prevented moving forward and backward when door is closed, and plays the weight that supports door leaf again, prevents the distortion of door, improves the application life of door;

4. the side at the door opening direction is provided with rear roller, plays the weight effect of supporting door when opening, prevents the distortion of door, improves the application life of door;

5. door leaf is provided with perforated plate, has so both reduced the quantity of the fence on the door leaf, has reduced the weight of door, to opening or close the influence of door, prevents that simultaneously the thief from entering inside between the fence when having prevented strong wind again;

6. above door pillar, be provided with the side directive wheel, prevent the swing of door.

7. the upper door frame of door is provided with ornamental strip, has beautified the outward appearance of door.
