[0015] A load-bearing rod is provided inside the installation groove, and the number of the load-bearing rods is multiple.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the train floor frame which is easy to install comprises a connecting piece, a moving block, a first groove, a spring, a limiting groove, a latch and a third groove. When the connecting piece needs to be installed, the moving block is aligned with the position of the first groove, and then the connecting piece is pressed downward so that the inclined surface of the moving block contacts the edge of the first groove, and then the inclined surface of the moving block is squeezed, so that the adjacent moving blocks gradually approach each other, and at the same time the spring is compressed, so that the moving block can move downward along the first groove, and then the moving block moves to the inside of the limiting groove, and the spring rebounds, so that the moving block returns to its original position, so that the moving block is limited by the limiting groove, so that the connecting piece is fixed. When the connecting piece needs to be removed, the connecting piece is pulled outward with force, so that the latch is engaged. The moving block moves in the third groove, so that the moving blocks are close to each other, and at the same time the spring contracts, so that the moving block can be moved out of the third groove, and then the moving block can be moved out of the first groove. At this time, the connecting piece is disassembled. Compared with the existing train floor frame, when in use, the vertical piece and the connecting piece are usually fixedly connected by bolts, but when the frame needs to be removed for maintenance, the bolt connection will make the disassembly and assembly of the frame extremely inconvenient, which wastes the working time of the maintenance personnel and is not conducive to the disassembly and assembly of the train floor frame. The easy-to-install train floor frame can easily disassemble and assemble the vertical piece and the connecting piece, saves the working time of the maintenance personnel, and is conducive to the disassembly and assembly of the train floor frame.

[0018] 2. Compared with the existing technology, this train floor frame is easy to install. Through the load-bearing rod, the first movable groove, the second movable groove and the installation groove, the load-bearing rod can be placed along the first movable groove and then fall into the second movable groove. It can be moved in the second movable groove and placed in the installation groove, which is convenient for the installation of the load-bearing rod, and the load-bearing rod facilitates the placement of the floor.
