In order to realize the stable installation of the combined type track 2, as shown in fig. 5, the combined type track further comprises U-shaped seats 2.3 which are arranged on the base 3 at intervals, wherein the side surfaces of two adjacent U-shaped seats 2.3 are connected with the first track 2.1 and the open grooves of the U-shaped seats 2.3 are provided with the second track 2.2, and the length of the second track 2.2 is slightly equal to that of the U-shaped seats 2.3. The first rail 2.1 is provided with a rectangular flat plate structure and connected to the side surfaces of the two adjacent U-shaped seats 2.3, and the second rail 2.2 is arranged to be a long-strip-shaped cylinder or round tube structure and connected above the U-shaped seats 2.3.
As shown in fig. 1 and 4, the first rail 2.1 and the second rail 2.2 are arranged at intervals along the longitudinal direction, the end of the first rail 2.1 and the end of the second rail 2.2 have a section of overlapping area on the U-shaped seat 2.3, and the spatially overlapping area of the first rail 2.1 and the second rail 2.2 on the U-shaped seat 2.3 is an overlapping section, when the roller 1.1 runs on the overlapping section, the first rail 2.1 and the second rail 2.2 simultaneously serve as the bearing rail surface of the roller 1.1 and are respectively contacted with the first tread 1.1a and the second tread 1.1 b; when the roller 1.1 drives away from the overlapping section, the first rail 2.1 or the second rail 2.2 is solely used as a bearing rail surface of the roller 1.1.
Since there is no obstruction in the middle side of the first track 2.1, it is convenient to arrange a translation or swing mechanism to move the moving member 4 with the roller device 1 laterally along the first track 2.1 (i.e. to disengage or drive into the sectional track 2) to the upper or lower track, as shown in fig. 3, thereby freeing up track space for other moving members 4.
As shown in fig. 2 and 8, the roller device 1 includes a wheel seat 1.2 and a roller 1.1 rotatably disposed on the wheel seat 1.2, the roller 1.1 includes a first tread 1.1a and a second tread 1.1b concentrically arranged, and the first tread 1.1a and the second tread 1.1b are respectively matched with the first rail 2.1 and the second rail 2.2. In order to ensure that the roller 1.1 can be doubly coupled with the combined rail 2, the first tread 1.1a and the second tread 1.1b are respectively set to be an annular cylindrical surface and an annular circular arc surface, so that the first tread 1.1a and the second tread 1.1b can be respectively matched with the first rail 2.1 and the second rail 2.2, and further, the roller devices 1 on the moving component 4 can be ensured to run stably.

Preferably, the arc radius of the second tread 1.1b is slightly larger than the radius of the second rail 2.2 matched with the second tread so as to reduce the matching difficulty of the wheel and the rail and ensure that the roller 1.1 slides smoothly, and the two sides of the second tread 1.1b are provided with protruding rims 1.1c so as to prevent the roller 1.1 from falling off the second rail 2.2 in the running process.

In order to better match the movement of the roller 1.1, as shown in fig. 5, the first rail 2.1 and the second rail 2.2 are staggered by a certain distance in the transverse direction (perpendicular to the track direction), a space is reserved for the rim 1.1c of the roller 1.1 to pass through, the relative height and the transverse distance of the first rail 2.1 and the second rail 2.2 are matched with the first tread 1.1a and the second tread 1.1b of the roller 1.1, so that when the roller 1.1 passes through an overlapping area, the first tread 1.1a can be contacted with the top surface of the first rail 2.1, meanwhile, the second tread 1.1b can also be contacted with the top of the second rail 2.2, and the first rail 2.1 and the second rail 2.2 simultaneously support the roller device 1 and the carrying moving member 4 thereof; when the roller device 1 leaves the overlapping area, the roller device can be smoothly switched to the first track 2.1 or the second track 2.2, so that the roller device 1 can continuously run within the length range of the combined track 2.
