## Abstract

An accommodating structure with a belt transmission structure. Two tracks are fixed on a body by several joining elements. Several sliding teeth are provided around the tracks. A belt is fixed at the sliding teeth along the loop structure of the tracks. The belt winds around the tracks as the sliding teeth slide.

## Claims

### Claim 1

An accommodating structure with a belt transmission structure, comprising:
a body having an accommodating space for holding objects;
two tracks, each of which forms a continuous loop structure, the tracks being fixed to two opposite sides of the body and extending along the edges of the body to corners in touch with the ground;
a plurality of sliding teeth disposed along the loop structure of the tracks in a slideable way and exposed from the corners of the body, each of the sliding teeth having a roller in touch with the track as the sliding tooth slides; and
a belt fixed on the sliding teeth along the loop structure of each of the tracks and winding around the track as the sliding teeth slide.

### Claim 2 (depends on 1)

The accommodating structure with a belt transmission structure of claim 1, wherein the two tracks have frames in the loop structure and the joining elements are cylinders going through the frame to be fixed on the body.

### Claim 3 (depends on 1)

The accommodating structure with a belt transmission structure of claim 1, wherein each of the tracks has two engaging grooves on both sides, each of the sliding teeth has two hook parts on both sides, and the two hooks correspondingly engage the two engaging grooves of the track.

### Claim 4 (depends on 1)

The accommodating structure with a belt transmission structure of claim 1, wherein each of the sliding teeth has two hollow parts with a spacer in between, an axle goes from both side inside the sliding tooth through the two hollow parts and the spacer, the axle in the hollow parts is pivotally mounted with the roller, each of the tracks has a guiding groove for the corresponding roller, and the roller rolls on the bottom of the guiding groove when the sliding tooth is under a force.

### Claim 5 (depends on 1)

The accommodating structure with a belt transmission structure of claim 1, wherein each of the sliding teeth uses an end cap on the outer side to fix the corresponding belt.
