Photovoltaic system rapid clamping structure

The utility model discloses a photovoltaic system rapid clamping structure. The rapid clamping structure comprises a clamping rail and a clamping block. The clamping rail is provided with a first clamping edge and a second clamping edge. The clamping block comprises a first sidewall and a second sidewall. The bottom of the first sidewall and the bottom of the second sidewall are provided with a first bayonet and a second bayonet respectively, wherein the first bayonet and the second bayonet are adapted to the first clamping edge and the second clamping edge respectively. The first sidewall is provided with a first demising groove which can be used for causing the first bayonet and the second bayonet of the clamping block both to be sleeved into the clamping rail when the clamping block is in the inclined condition. The first demising groove and the first bayonet are in inclined surface transition connection or in arc transition connection. The arrangement of the first demising groove can cause the first bayonet and the second bayonet of the clamping block both to be sleeved into the clamping rail when the clamping block is in the inclined condition, and the clamping block is straightened through the pressing rotation operation so as to realize the clamping fit of the clamping block and the clamping rail. The disassembly and assembly process of the rapid clamping structure can be completed only by hands, and the disassembly and assembly process is simplified, so the time consumed in the assembly process of the photovoltaic system can be effectively reduced, so that the assembly cost is reduced.
