The combined trolley further comprises a magnet 7, wherein the magnet 7 is used for forcing the connecting piece 3 to be spliced on the second trolley frame 2. In actual use, if first bogie frame 1 assembles on second bogie frame 2, connect 3 automatic grafting is on second bogie frame 2 under the magnetic force effect of magnet 7, need not the removal of user manual drive connecting piece 3, has further made things convenient for the operation, and on the other hand, magnet 7 has also improved the connection fastness of connecting piece 3 and second bogie frame 2.

The magnet 7 is arranged on the connection piece 3 and the second bogie frame 2 comprises a magneto-philic element 8. Magnetic force can be generated between the magnet 7 and the magneto-philic element 8, and under the action of the magnetic force, the connecting piece 3 can be automatically inserted on the second bogie frame 2. The magneto-philic element 8 is made of a magneto-philic material, which may be iron. The overall structure of the magneto-philic element 8 is plate-shaped, and the magneto-philic element 8 is fixedly arranged on the second bogie frame 2. The whole structure of the connecting piece 3 is hollow, and the magnet 7 is arranged in the connecting piece 3.

The first bogie frame 1 includes a first pin hole 11, and the connector 3 is slidably disposed in the first pin hole 11. If the connector 3 slides within the first pin bore 11, the connector 3 may extend out of the first pin bore 11 or retract within the first pin bore 11. If the connecting element 3 protrudes outside the first pin hole 11, the connecting element 3 can be plugged onto the second bogie frame 2. When the connecting member 3 is extended and contracted in the first pin hole 11, the connecting member 3 can be separated from the second bogie frame 2. The structure in which the link 3 is slidably disposed in the first pin hole 11 improves the structural compactness of the link 3 and the first bogie frame 1.

The first pinhole 11 is the blind hole, and first bogie frame 1 includes through-hole 12, and through-hole 12 is located the bottom of first pinhole 11, and stay cord 5 wears to locate through-hole 12 and connect on connecting piece 3, because footboard 4 passes through stay cord 5 to be connected on connecting piece 3, and footboard 4 is spacing with connecting piece 3 to slide in first pinhole 11 to the reliability of assembly has been improved.

The second bogie frame 2 includes a second pin hole 21, and the connector 3 is insertable into the second pin hole 21. If the connector 3 extends out of the first pin hole 11, the connector 3 may be inserted into the second pin hole 21. If the connector 3 is retracted within the first pin bore 11, the connector 3 may be disengaged from the second pin bore 21. The magneto-philic element 8 is fixedly arranged in the second pin hole 21.
