Three-section synchronous slide rail

A three-section synchronous slide rail, comprising:

• two sets of slide rail assemblies, wherein the two sets of the slide rail assemblies are respectively installed with synchronization components, the slide rail assemblies respectively comprise a fixed rail, a middle rail and a sliding rail, the synchronization components respectively comprise a flexible deflector unit and a roller provided on the middle rail, the flexible deflector unit is respectively connected with the fixed rail and the sliding rail, wherein the middle rail is further connected with a rope base, the rope base is capable of rotating on the middle rail, a first end of the flexible deflector unit is wound around a first end of the rope base and then fixed to the rope base, and a second end of the flexible deflector unit bypasses the roller, then is reversely wound on a second end of the rope base and fixed to the rope base, and a connecting rod is connected between the rope bases of the two sets of the slide rail assemblies;
• wherein a first connector is fixedly connected with the sliding rail, a second connector is fixedly connected with the fixed rail, and the first connector and the second connector are respectively configured to connect the flexible deflector unit;
• wherein a spiral groove is provided on the rope base, and the flexible deflector unit is wound on the rope base along a rotation path of the spiral groove;
• wherein the flexible deflector unit comprises a first flexible deflector, a second flexible deflector, and a third flexible deflector;
• wherein a first end of the first flexible deflector is fixed and wound on the rope base, and a second end of the first flexible deflector is connected to a first end of the third flexible deflector via the first connector, and a second end of the third flexible deflector is connected to a first end of the second flexible deflector through the second connector after bypassing the roller;
• a second end of the second flexible deflector is wound and connected on the rope base.
