The present invention is further detailed explanation with reference to the accompanying drawings and detailed description:
Refer to Fig. 1, Fig. 2, the utility model provides a kind of laborsaving hydraulic jack, including support 1, be fixed on support 1 On oil pump 2 and the pump core 3 in oil pump 2, pump core 3 is connected with handle 4, and handle 4 is mutually cut with scissors by connecting rod 201 with oil pump 2 Connect, support 1, which is provided with hydraulic cylinder 5, hydraulic cylinder 5, is provided with piston 6, and piston 6 is connected with piston rod 7, and the one end of piston rod 7 passes liquid Cylinder pressure 5 is outer and is connected with hoistable platform 8, and the inner space of hydraulic cylinder 5 is connected by oil transportation runner 9 with oil pump 2, the handle 4 One stroke hole 10 is provided with, the port position of stroke hole 10 is provided with spacing ring 11;The handle 4 is connected with an extension spanner 12;Institute The connecting rod 13 that extension spanner 12 includes matching with stroke hole 10 is stated, connecting rod 13 is located in stroke hole 10;The extension is pulled A movable span 14 is provided with hand 12;Motion bar 15 is provided with the movable span 14;Described one end of motion bar 15 passes movable span 14, The end both sides of motion bar 15 are hinged with mutually symmetrical gag lever post 16, and gag lever post 16 is located in stroke hole 10 and is pressed on stroke hole On 10 inwalls;The gag lever post 16 is hinged by wind spring with motion bar 15;A sheath 17 is arranged with outside the extension spanner 12; It is arranged with outside the extension spanner 12 in the position of sheath 17 provided with an adjustment hole 18 connected with movable span 14;The regulation A regulating block 19 is provided with hole 18, regulating block 19 is connected with motion bar 15;The regulating block 19 and the end wall surface of adjustment hole 18 1 Between be provided with a spring 20;The regulating block 19 is in direct triangle, and side is inclined plane 1901;Set on the sheath 17 There is and the pressing hole 21 that connects vertical each other with adjustment hole 18;One button 22 is installed in the pressing hole 21;It is described to press The bottom of button 22 has cut an angular cut 23, and the inclined-plane of angular cut 23 is consistent with the angle of inclination of the inclined plane of regulating block 19, beveling Fitted with the upper end of the inclined plane of regulating block 1,901 23 inclined-plane lower ends of mouth.
The inwall of pressing hole 21 is provided with an annular regulating tank 24;It is arranged with outside the button 22 and the annular phase of regulating tank 24 The guide part 25 of matching, guide part 25 is located in annular regulating tank 24.
Application method of the present utility model is as follows:
When needing to use hydraulic jack, first hoistable platform is placed under the object for needing to push, can then held Sheath 17, but without being pressed down on to button 22, now extend the contracting completely of connecting rod 13 of spanner 12 in stroke hole 10, Extension spanner 12 is mutually fixed by gag lever post 16 with handle 4, when user of service, which holds sheath 17, lifts extension spanner 12 upwards, Handle 4 is also lifted upwards therewith, and when handle 4 is lifted upwards, pump core 3 starts as handle 4 is subjected to displacement, towards oil pump 2 Outer movement, hydraulic oil is inhaled into oil pump 2, after certain position is lifted on user of service, and extension spanner 12 just can be pulled downwards, is led to Crossing handle 4 makes pump core 3 again in retraction oil pump 2, and the pump core 3 that the hydraulic oil in oil pump 2 is retracted into is extruded, and passes through oil transportation runner 9 Hydraulic oil is squeezed into hydraulic cylinder 5, so as to promote piston 6, makes piston 6 drive piston rod 7 to be overhang to hydraulic cylinder 5, with Piston rod 7 is protruding, and the hoistable platform 8 being connected with piston rod 7 also rises therewith lifts part, as user of service constantly repeats The action lift upwards, pulled downwards, can constantly input hydraulic oil to hydraulic cylinder 5, make the constantly rising of hoistable platform 8 Object is constantly pushed upwards.
User of service, can be right during sheath 17 is held when feeling laborious during pulling extension spanner 12 Button 22 is pressed down on, and, the angular cut inclined-plane of the bottom of button 22 can be inclined along regulating block 19 with button 22 downwards The track of plane 1901 is moved, button 22 under the limitation of pressing hole 21, can only do it is vertical move down action, therefore with by Button 22 is constantly moved down, and regulating block 19 can be subjected to displacement under the pressure of button 22, constantly towards adjustment hole 18 away from movable span 14 One end movement, spring 20 compressed, and with the movement of regulating block 19, the motion bar 15 being connected with regulating block 19 constantly to Retraction in movable span 14, under the pulling of motion bar 15, gag lever post 16 is no longer pressed on the inwall of stroke hole 10, gag lever post 16 The position being hinged with motion bar 15 is drawn into movable span 14, and the in-line originally formed between two gag lever posts 16 then becomes Into V-shaped, and as motion bar 15 is constantly toward inside contracting, the angle of the angle of two formation of gag lever post 16 also can be smaller.
When gag lever post 16 is no longer pressed on the inwall of stroke hole 10, the connecting rod 13 of extension spanner 12 just can freely be expert at Carry out activity in journey hole 10, can now be pulled by 0 pair of extension spanner 12 of external force, make the connecting rod 13 of extension spanner 12 not Disconnected to extend out to outside handle 4, the length that can be formed between extension spanner 12 and handle 4 constantly increases, when the length reaches actual Taken, just can stop the movement of connecting rod 13, then release button 22, lose pressing after dynamic pressure for button 22, in spring 20 Its own resilient effect under, regulating block 19 resets, motion bar 15 drive gag lever post 16 stretch out, gag lever post 16 in the presence of wind spring again The secondary inwall of stroke hole 10 that is pressed on is up, is fixed again between handle 4 and extension spanner 12, now with connecting rod 13 Stretching extends handle 4 and is initially able to the length to be formed with extension spanner 12, so as to add the arm of force, reduces user of service and pulls The power that dynamic extension spanner 12 is needed to use, serves labour-saving effect, also can be easily to extension spanner even if the less people of strength 12 are pulled, and can be pulled for a long time, and after the extension extending length of spanner 12, extension spanner 12 can pass through limit Position bar 16 is fixed with handle 4 automatically, is not in situation about coming off.
Gag lever post 16 with motion bar 15 be drawn into movable span 14 when, the angle formed between gag lever post 16 is consistently greater than 0 degree, the section diameter that gag lever post 16 opens is more than the diameter of movable span 14, when connecting rod 13 is moved to spacing ring, gag lever post 16 can collide with spacing ring 11, and spacing ring 11 is by limiting gag lever post 16 so as to ensure that connecting rod 13 will not be fully extended Outside stroke hole 10, make the state all the time in connection between extension spanner 12 and handle 4.
The inwall of pressing hole 21 is provided with the guiding for being arranged with and matching with annular regulating tank 24 outside annular regulating tank 24, button 22 Portion 25, guide part 25 is located at annular regulating tank 24, and the presence of guide part 25 ensure that stability when button 22 is moved, and ring Shape regulating tank about 24 two side walls can play spacing effect, make button 22 pressing when will not be fully sunk in pressing hole In 21 and buttons 22 when regulating block 19 resets will not the power of the generation of regulating block 19 eject to outside pressing hole 21.
