The utility model discloses a stair -climbing triangular wheel with brake function, apply to in the cart, and the stair -climbing triangular wheel includes frame, axle and triangular wheel subassembly, and the triangular wheel subassembly includes triangular wheel frame and three gyro wheels on the triangular wheel frame, and the stair -climbing triangular wheel still includes sliding sleeve structure, drive unit and brake frame, two sliding sleeve structures are respectively slidingly connected in the both sides of axle, and drive unit is located between two sliding sleeve structures, is used for driving sliding sleeve structure to move to triangular wheel subassembly, is equipped with first return spring between sliding sleeve structure and frame, brake frame slidingly connects on the triangular wheel frame, and brake frame is located between triangular wheel subassembly and sliding sleeve structure, is equipped with first brake structure on brake frame and gyro wheel, and is equipped with second brake structure between triangular wheel frame and sliding sleeve structure. The user through drive unit realizes synchronous locking of triangular wheel gyro wheel and triangular wheel frame, and the security of using above -mentioned stair -climbing triangular wheel with brake function is ensured.

The present application relates to photovoltaic support technical field, especially a mountain photovoltaic support locking anti-loose structure and installation method, including mounting plate and limiting piece, the mounting plate is provided with drive assembly, drive assembly is connected with a plurality of limiting piece power, the mounting plate is provided with positioning assembly, the side of mounting plate is connected with support frame, and the fixed assembly that is matched with drive assembly is installed on the positioning plate, through rotating drive ring, the arc slot on drive ring is used with the drive column on multiple L type board cooperation, converts rotary motion into the linear translation movement of multiple limiting piece, only single person single operation is needed, can drive multiple limiting piece to extend simultaneously and carry out the clamping fixation to photovoltaic module, ensures that photovoltaic module four around is received uniform consistent clamping force, only allows drive ring to rotate forward in the whole process of clamping drive to promote limiting piece, prevents loosening in the middle when fixing photovoltaic module, reduces installation difficulty.

The utility model relates to the technical field of anti-over-rotation devices, and discloses a swivel bridge anti-over-rotation device which comprises a main body assembly. The main body assembly comprises a mounting seat, a first rod body and a second rod body; the second rod body is arranged on the first rod body; the upper turntable is arranged above the rod body II; a limiting assembly is arranged on the second rod body. The limiting assembly comprises an electric push rod which is fixedly connected into the first rod body and fixedly connected with the second rod body. When the rotating bridge is used, after the rotating bridge body is rotated and folded, the electric push rod is started, the telescopic rod and the clamping block are sequentially embedded into the first groove body and the second groove body, locking of the angle of the upper rotating disc is achieved, locking is canceled on the contrary, and the rotating bridge has the advantages that over-rotation of the rotating bridge is prevented, the automation degree is high, and locking of the upper rotating disc is conveniently canceled; the problems that an existing anti-over-rotation device of the swivel bridge is low in automation degree, and a locking mechanism is inconvenient to take out from a clamping groove are solved.
