When the pressing lock head is in the unlocked state, the limiting rod is limited by the tip of the heart-shaped guide groove, and the lock head is in the retracted state. When the sliding wheel support is installed, the connecting rod at the lower end thereof can be inserted into the positioning hole in the tongue lock seat, and then the pressing blocks on both sides of the tongue lock seat are pressed to make the lock head extend from the inner side of the positioning hole along the inner cavity of the tongue lock seat and snap into the round hole slot on the positioning head at the lower end of the connecting rod. Under the action of the pressing force, the limiting rod slides along the lower part of the heart-shaped guide groove to the rear end V-shaped groove part to limit the extension of the lock head, so that the sliding wheel assembly is installed and fixed, and it needs to be disassembled. When the sliding wheel assembly is in operation, the pressing block is pressed again to make the limit rod slide along the upper part of the heart-shaped guide groove to the front end tip under the action of pressure. At this time, the lock head is retracted under the resetting action of the spring and disengaged from the positioning hole to unlock the sliding wheel assembly, which is convenient for disassembly and replacement. No external tools are required during the disassembly and assembly process, which solves the problem that the sliding wheel and the mounting surface of the existing sliding door sliding wheel assembly are fixed with screws, and the sliding wheel is a wearing part. As the use time increases, the surface is prone to wear and non-positive force is generated, which makes the sliding door not smoothly pulled out, and the use of screw-type connection makes it inconvenient to disassemble and assemble the sliding wheel.
