This utility model discloses a plate dumbbell, relating to the field of fitness equipment technology. The plate dumbbell consists of a connector, dumbbell plates, and a dumbbell bar. The screw of the connector passes through the dumbbell plates and is inserted into the dumbbell bar. Locking devices are provided on the connecting terminals at both ends of the dumbbell bar. One end of the locking device engages with the screw of the connector to fix the screw, so that the end of the connector and the connecting terminal clamp the dumbbell plates to form the plate dumbbell. When the screw is disengaged from the dumbbell bar, the screw can slide relative to the dumbbell bar, which facilitates quick adjustment of the position of the connector and completes the assembly and disassembly of the dumbbell plates, realizing the rapid assembly of the plate dumbbell. By moving the locking device, the fixing and loosening of the connector can be controlled, thereby completing the assembly and disassembly of the dumbbell plates and adjusting the weight of the plate dumbbell. The locking device in this plate dumbbell has a simple structure and is easy to operate.
