The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 to Fig. 4, a kind of portable hand hydrodynamic pressure is cut, and comprises manual hydraulic device and scissors apparatus, and manual hydraulic device is positioned at afterbody, and scissors apparatus is positioned at head;
Referring to Fig. 1, manual hydraulic device comprises depression bar 1, small cylinder 2, big hydraulic cylinder 4, spring 11, fuel tank 9, check valve, stop valve 10; Fuel tank 9 and big hydraulic cylinder 4 are placed side by side, and communicate through oil pipe in both bottoms, and hand stop valve 10 is housed on the oil pipe; Small cylinder 2 is housed on fuel tank 9, and small piston rod 3 ends of small cylinder 2 are connected on the depression bar 1, and an end of depression bar 1 is the hinged securement point, and depression bar 1 other end is as handle; Small cylinder 2 lower cavity are equipped with two oil pipes, check valve 7,8 all is installed on the oil pipe, an oil pipe leads to fuel tank 9, another root oil pipe leads in the cavity of big hydraulic cylinder 4 one sides, be set with spring 11 on the big piston bar 6 of big hydraulic cylinder 4, spring 11 1 ends withstand big piston 5, and the other end withstands big hydraulic cylinder 4 sidepiece inwalls.Small cylinder 2 lower cavity are led to first check valve 7 that is equipped with on the oil pipe of fuel tank 9 for flowing to fuel tank 9 for closing, and another root leads to second check valve 8 that is equipped with on the oil pipe in the big hydraulic cylinder 4 one side cavitys for flowing to small cylinder 2 cavitys for closing.
Referring to Fig. 2, scissors apparatus comprises spiral arm 12, upper scissor blade 14, lower scissor blade 15, straight pin 16,17, support 18, upper and lower two cutting edges, 14,15 1 side ends have the duct, pass second straight pin 16 in the duct and connect location formation pivot point, second straight pin 16 passes support 18 and is fixed on the support 18, support 18 fuses with big hydraulic cylinder 4, upper and lower two cutting edges, 14,15 end side also have the duct, pass pin 13 in the duct and be connected with spiral arm 12 respectively, two spiral arms 12 are connected with big piston bar 6 tops through first straight pin 17.
The utility model portable hand hydrodynamic pressure is cut the course of work:
When depression bar 1 upwards lifts, the small piston rod 3 of small cylinder 2 moves upward, and small cylinder 2 cavity of resorption volumes form parital vacuum, and the fluid of fuel tank 9 is closed second check valve 8 of right-hand member through fuel sucking pipe under the atmospheric pressure effect, back down first check valve 7 of left end, enter small cylinder 2 cavity of resorptions.When the downward pressure drop of depression bar 1, small cylinder 2 cavity of resorption volumes reduce, fluid is squeezed, pressure raises, close left end first check valve 7, back down right-hand member second check valve 8, fluid enters the left chamber of big hydraulic cylinder 4 one sides through oil exit pipe, thereby drive big piston 5 compression springs 11, promotion big piston bar 6 withstands scissors apparatus and shears.If open stop valve 10, the logical fuel tank 9 in big hydraulic cylinder 4 left chambeies, pressure descends, because the reaction force of spring 11, fluid is extruded and flows back to fuel tank 9 rapidly, makes blading device return to the home position rapidly.
On, following two cutting edges 14,15 connect the location with second straight pin 16 and form pivot point.Big piston bar 6 tops and first straight pin 17 fuse, and first straight pin 17 is positioned two spiral arms 12 for a place.When the big piston 5 of big hydraulic cylinder 4 moves, two spiral arms 12 are subjected to big piston bar 6 thrust forward, the while opened with certain angle, power is passed to upper and lower two cutting edges 14,15, make upper and lower two cutting edges 14,15 be directed to second straight pin 16 (fulcrum) direction and produce clockwise and counterclockwise turning moment, shear thereby promote upper and lower cutting edge 14,15 rotations.
The utility model is simple to operate, easy to carry.
