Built-in type dumping fork

The utility model relates to a built-in type dumping fork, which mainly consists of a base (1), a cargo fork frame (2), a cargo retaining frame (3), an oil cylinder (4) and a spring (5). The built-in type dumping fork is characterized in that the base (1) is directly arranged on a forklift inner gantry, the two ends of the oil cylinder (4) are respectively arranged on the base (1) and the cargo fork frame (2), the cargo fork frame (2) is upwards tilted with 25 degrees and downwards titled with 45 degrees through the operation of a hydraulic oil line, and the two ends of the spring (5) are respectively arranged on the cargo fork frame (2) and the cargo retaining frame (3). When the cargo fork frame is reset after downward tilting with 45 degrees, the spring is tensioned, and the cargo retaining frame (3) is simultaneously reset, so the resetting effect of the cargo retaining frame (3) is realized. The built-in type dumping fork has the advantages that a plenty of heavier cargo can be carried, and the effects of quick dumping during downward tilting and stable transportation during upward tilting are realized; the built-in type dumping fork is directly arranged on the forklift inner gantry, the load loss distance is shortened, the plenty of heavier cargo can be carried by a forklift, the cargo can be quickly dumped during downward tilting through hydraulic operation, and be stably transported during upward tilting, and the working time of the forklift and drivers is greatly reduced.
