Abstract
The utility model relates to a multifunctional hydraulic jack, comprising a piston, a piston rod, a piston cylinder, a casing adjusting screw, a piston nylon bowl, an unloading rod, an oil pump cylinder, an oil pump core, a rubber ring for the oil pump piston. The structural characteristic is that a Z-shaped cross claw is added on the original structure, and the base is improved. The utility model has two functions of forward lifting and sideways lifting, having the advantages of reasonable structure, easy fabrication, and convenient use, which is a convenient tool for lifting weight.
Description
The utility model relates to a kind of hydraulic jack, especially a kind of jack with forward jacking and side direction jacking function.
General hydraulic jack only has forward jacking function or side direction jacking function, and two kinds of jacking functions can not possess simultaneously.Jack with forward jacking function is with its jacking weight the time, must be placed under the weight, be weight apart from ground height must (with 10 tonnes jacks be example greater than the minimum altitude of jack, its minimum altitude is of a size of about 240mm) could work, if minimum altitude less than jack, also need the jack of a side direction jacking, the two replaces compounding practice.
The purpose of this utility model is for a kind of multifunction hydraulic jack with forward jacking and side direction jacking is provided.
The utility model is on the basis of former hydraulic pressure jack, carries out the improvement of structure, and develops a kind of novel multifunctional hydraulic jack.Former hydraulic pressure jack mainly comprises piston, piston rod, piston cylinder, overcoat, top cap, parts such as adjusting screw(rod), piston nylon bowl, unloader lever, pump cylinder, oil pump core, oil pump piston cushion rubber.Architectural feature of the present utility model is to have increased a upper end of Z-shapedly striding pawl, striding pawl circular hole is arranged on the architecture basics of above-mentioned former hydraulic pressure jack, to stride the top that pawl is enclosed within piston rod by this circular hole, with bolt, nut, semicircle flange and platen will stride pawl and piston rod is fixed as one, make and stride the lifting simultaneously of pawl, piston rod and adjusting screw(rod).Sliding shoes is housed striding the pawl inboard, sliding shoes can slide up and down along the guide plate on the base, at sliding shoes and stride the adjusting pad is housed between the pawl, can regulate the gap of striding between pawl and base guide plate at any time by this adjusting pad, on striding pawl, be provided with the leader, for one hand is mentioned jack.Having increased a back in the side of base has the guide plate of strengthening gusset, and weight also can reduce to stride simultaneously the friction drag of pawl and guide plate to the diametral load of jack when supporting the side direction jacking with it.Be positioned to stride on pawl two side positions in the place ahead of base and be provided with projected claw, when playing the side direction jacking, the supporting role of weight.In the both sides of base a handle is arranged respectively, help two hands jack is delivered under the weight, or take out jack during end-of-job.
Below in conjunction with accompanying drawing architectural feature of the present utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2, Fig. 3, Fig. 4, Fig. 5 are that side pushes and makes scheme drawing.
Fig. 6, Fig. 7, Fig. 8 are forward jacking action scheme drawings.
Wherein: 1 semicircle flange, 2 nuts, 3 platens, 4 stride pawl, 5 bases, 6 sliding shoes, 7 off-load screw rods, 8 piston nylon bowls, 9 pistons, 10 piston rods, 11 piston cylinders, 12 overcoats, 13 top caps, 14 adjusting screw(rod)s.
Nut 2 in the utility model, off-load screw rod 7, piston nylon bowl 8, piston 9, piston rod 10, piston cylinder 11, overcoat 12, top cap 13, adjusting screw(rod) 14 and oil pump core, pump cylinder, parts such as oil pump piston cushion rubber all with identical, the semicircle flange 1 of framing member of known hydraulic jack, platen 3 also is general part, does not have the specific (special) requirements can be by the manufacturing of Fig. 1 structure.Striding pawl 4 and base 5 can be according to said structure feature and structure manufacturing shown in Figure 1.
Operating principle of the present utility model is the same with existing general hydraulic jack, closes off-load screw rod 7 earlier at prestart, by handle the oil pump core is started working, and high-voltage oil liquid is delivered to the piston bottom promote piston rod 10 risings, and weight is realized jacking work.Left-hand revolution off-load screw rod 7 during off-load, piston rod 7 are under gravity or external force effect just in the regracting piston cylinder 11.
Utilize the utility model can realize that the side top is shown in Fig. 2-5, simultaneously also can the forward jacking shown in Fig. 6-8, also can side top and forward jacking carry out continuously, shown in Fig. 2-8, earlier the weight side is pushed up certain height, utilize supporter supports to live weight, jack is set back carry out the forward jacking more then.The utility model is to combine having the forward jacking jack of simple function and the jack of single side direction jacking, improvement by structure, make two kinds of jacks become a kind of later-model jack, its function is the summation (top lifting height as 10/5 ton of multifunction hydraulic jack is 24-560mm) of two kinds of jacks.The utility model is rational in infrastructure, makes simple, easy to use.It is a kind of instrument that makes things convenient for of jacking weight.
Claims (1)
- A kind of hydraulic jack that is used for the jacking weight, mainly comprise piston, piston rod, piston cylinder, overcoat, the top cap, adjusting screw(rod), piston nylon bowl, unloader lever, pump cylinder, the oil pump core, parts such as oil pump piston cushion rubber, it is characterized in that on original design, increasing the Z-shaped pawl of striding, stride the pawl upper end circular hole is arranged, to stride the top that pawl is enclosed within piston rod by this circular hole, use bolt, the semicircle flange, platen and nut will stride pawl and piston rod is fixed as one, can make and stride pawl, the lifting simultaneously of piston rod and adjusting screw(rod), sliding shoes is housed striding the pawl inboard, this sliding shoes can slide up and down along the guide plate on the base, at sliding shoes and stride the adjusting pad is housed between the pawl, can regulate at any time and stride pawl and the end and sit gap between guide plate, one handgrip is set striding the pawl upper end, the side of base has increased a back the guide plate of strengthening gusset, be positioned to stride on pawl two side positions in the place ahead of base and be provided with projected claw, when playing the side direction jacking,, a handgrip is respectively arranged in the both sides of base to the supporting role of weight.
