[0026] As Figures 1-7The utility model provides a portable hydraulic pressure intensifier, including the pressure intensifier main part 1, the output end oil inlet and return joint group 2 of intercommunication setting in the pressure intensifier main part 1 one end and the input end oil inlet and return joint group 9 of intercommunication setting in the pressure intensifier main part 1 other end, still include: the casing 10, fixed cover is located the outside of pressure intensifier main part 1, the top fixed setting of casing 10 has the handle 8, a plurality of fixed support feet 3 are fixedly arranged at the bottom four corners of casing 10, four telescopic support foot assemblies 4 are hingedly arranged at the bottom four corners of casing 10, the bottom center of casing 10 is fixedly provided with a clamping block 5, and the clamping block 5 is provided with a clamping groove 6 for clamping the telescopic end of telescopic support foot assembly 4.

[0027] When the pressure intensifier needs to be taken and carried, the handle 8 can be held to easily carry the pressure intensifier. When the pressure intensifier is placed on a relatively flat ground with a certain inclination, the telescopic support foot assembly 4 is kept in a folded state, the telescopic rod 41 is clamped in the clamping groove 6 of the clamping block 5, the pressure intensifier is in contact with the ground through the fixed support feet 3, and the pressure intensifier main part 1 can be stably placed. When the pressure intensifier is placed on uneven ground with deep water, the telescopic rod 41 is rotated outward around the hinge shaft assembly 44, and the length of the telescopic rod 41 in different telescopic support foot assemblies 4 is adjusted according to the terrain conditions. At this time, the heightening support feet formed by the four telescopic support foot assemblies 4 not only enable the pressure intensifier main part 1 to be stably placed on uneven ground, but also increase the height of the pressure intensifier main part 1 relative to the ground, so that the height of the pressure intensifier main part 1 is higher than the water level.

[0028] In an embodiment, the hinge shaft assembly 44 includes a bolt 441 threaded into the first hinge seat 42 and the second hinge seat 43, and a nut 442 threaded onto the bolt 441, the nut 442 is screwed and abuts the outer wall of the first hinge seat 42, so that the first hinge seat 42 and the second hinge seat 43 abut each other.

The supercharging valve group 104 can adopt a supercharging valve with a model number of HMG5.0-16 / 35 produced by Shenzhen Hengcheng Hydraulic Technology Co., Ltd., and the pressure regulating valve 106 can adopt a pressure regulating valve with a model number of RV10-20 produced by Hydros.
