Detailed Implementation

[0023] Example 1:

[0024] Reference Figures 1 to 6 A multi-functional track trolley includes a panel 1, casters 2, track wheels 3, and a pull rod 4. The bottom of the panel 1 is provided with two linearly distributed track wheels 3 and four rectangularly distributed casters 2 provided by folding parts. Each folding part is provided with a latch 5 on its side. The first end of the panel 1 is provided with a mounting groove 6, and the two ends of the mounting groove 6 are provided with mutually symmetrical fixing through holes 7. The bottom of the pull rod 4 is connected to a mounting block 8 that is adapted to the mounting groove 6. The mounting block 8 is provided with a mounting through hole 9 along its length. When installing the pull rod 4, the mounting block 8 is installed in the mounting groove 6 and inserted into the fixing through hole 7 and the mounting through hole 9 through a connecting rod 10.

[0025] The folding component is a hinge 11. The fixed side of the hinge 11 is fixed to the bottom of the panel 1, and the movable side of the hinge 11 is equipped with a caster wheel 2. The latch 5 is located on the side close to the movable side of the hinge 11.

[0026] Two latches 5 are provided on the side of each folding piece. The two latches 5 are arranged in a straight line. Each latch 5 includes a latch groove 12 and a latch tongue 13. The latch groove 12 is a hollow structure. A sliding groove 14 is opened at the top of the latch groove 12. The latch tongue 13 is slidably disposed in the latch groove 12. The latch tongue 13 is connected to a push-pull block 15, and the push-pull block 15 extends out of the sliding groove 14.

[0027] When hinge 11 folds and causes caster 2 to retract, the height of caster 2 is lower than the height of track wheel 3. When hinge 11 opens and causes caster 2 to lower, the height of caster 2 is higher than the height of track wheel 3.

[0028] This embodiment is for single-vehicle use, and can be divided into single-vehicle ground use and single-vehicle rail use.

[0029] When the bicycle is used on the ground, the mounting block 8 is installed in the mounting groove 6, and the connecting rod 10 is inserted into the fixing through holes 7 at both ends of the mounting groove 6 and the mounting through holes 9 of the mounting block 8, thereby connecting the pull rod to the panel 1. The hinge 11 is opened, and the locking tongue 13 is pushed out of the locking groove 12 by the push-pull block 15, and the locking tongue 13 is pressed against the movable side edge of the hinge 11, thereby fixing the movable side of the hinge 11. At this time, the universal wheel 2 is in the lowered state, and the height of the universal wheel 2 is higher than the height of the track wheel 3, so it moves on the ground by the universal wheel 2.

[0030] When using the single-car rail surface, push the locking tongue 13 back into the locking groove 12 by pushing the push-pull block 15, release the movable side of the hinge 11, fold the hinge 11, retract the caster 2, place the track wheel 3 on the subway track, and move the trolley on the track 23 by the track wheel 3.

[0031] Example 2

[0032] Reference Figure 7 The difference between this embodiment and embodiment one is that it also includes a splicing rod 16, and clearance positions 17 are respectively opened on both sides of the tail end of the panel 1 so that the middle protrusion of the tail end of the panel 1 forms a splicing block 18. The splicing block 18 has a splicing through hole 19 along its length direction. The splicing rod 16 is used to be inserted into the splicing through hole 19 to splice and combine at least two panels 1.

[0033] It also includes a decorative sleeve 20, which has a connecting hole 21. The decorative sleeve 20 is connected to the end of the splicing rod 16 through the connecting hole 21, and the decorative sleeve 20 is located in the clearance position 17.

[0034] When two panels 1 are spliced, the two panels 1 are arranged side by side, and the splicing rod 16 is inserted into the splicing through hole 19 of the two panels 1. A pull rod is installed in the mounting groove 6 of each panel 1 through the mounting block 8. The connecting rod 10 is inserted into the fixing through hole 7 of the two panels 1 and the mounting through hole 9 of the two mounting blocks 8.

[0035] When there are too many materials or the weight is large, they can be used by splicing two panels 1 together. When splicing, simply insert a splicing rod 16 into the splicing through hole 19 at the end of the two panels 1, and insert a connecting rod 10 into the fixing through hole 7 at the beginning of the two panels 1 and the mounting through hole 9 of the mounting block 8. The assembly is convenient and quick.

[0036] Example 3

[0037] Reference Figure 8 The difference between this embodiment and embodiment one is that when multiple panels 1 are spliced, the multiple panels 1 are arranged in two or more rows, and the two adjacent panels 1 in the same row are spliced ​​end to end, so that the splicing block 18 of the rear panel 1 is installed in the mounting groove 6 of the front panel 1, and the multiple panels 1 are connected by splicing rods 16 inserted into the splicing through hole 19 or the fixing through hole 7 and the mounting through hole 9.

[0038] A combination panel 22 is provided between two adjacent rows of panels 1, and the combination panel 22 is installed on the splicing rod 16.

[0039] In this embodiment, multiple panels 1 are arranged in two rows. The mounting groove 6 of the frontmost panel 1 in each row is connected to a pull rod via a mounting block 8. The mounting block 8 and the panel 1 are connected by a connecting rod 10 of appropriate length inserted into the fixing through hole 7 and the mounting through hole 9. The distance between the two rows of panels 1 is adapted to the spacing between the two tracks 23.
