Abstract
The utility model relates to an oil jack. When an existing jack jacks up a heavy object, the existing jack can only be arranged under the heavy object by providing a larger space cavity. The oil jack provided by the utility model can be arranged under the heavy object only by providing the space cavity of above 35 millimeters. The utility model is characterized in that a Z-shaped hook plate is connected with the projecting end of a sliding oil cylinder. The utility model has the advantages of simple structure and convenient usage.
Description
The utility model relates to a kind of oil jack.
At present, people generally adopt oil jack jacking weight, though the version of oil jack is various, its basic method of operation is all identical, jack is placed on below the weight earlier, then, the operating operation bar is with weight jack-up, the condition precedent that adopts this method is that the position of placing oil jack must be arranged below weight, and this position height must be greater than the length of jack, but in actual use, does not have this space below many weights, the weight pad risen and trouble very, sometimes even oil jack can't be used.
The purpose of this utility model is to provide a kind of oil jack, when using this jack, as long as there is the space more than 35 millimeters just can use below the weight.
The purpose of this utility model is achieved in that the external part at the piston rod of jack is connected with the Z type and colludes plate.The utility model is simple in structure, and is easy to use, multiple functional.
Below in conjunction with accompanying drawing its structure is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a birds-eye view of the present utility model;
Fig. 3 is a check valve scheme drawing of the present utility model.
The utility model comprises cylinder shell (1), cylinder body (2), cylinder shell (1) and cylinder body (2) constitute seal oil chamber (3), in oil pocket (3), fill hydraulic oil, in cylinder body (2), be provided with sliding plunger (4), sliding plunger (4) can slide in cylinder body (2), be provided with check valve (5) (see figure 2) and Dump valve (6) in the lower end of cylinder body (2), be primarily characterized in that also having additional the Z type on jack colludes plate (7), the end that the Z type colludes plate links to each other by bolt with the external part of sliding plunger (4).
When using the utility model, earlier the Z type being colluded plate (7) inserts below the weight, then, handle joystick, the hydraulic oil in the oil pocket (3) enters in the cylinder body (2) by check valve (5), promotes sliding plunger (4) upward movement, sliding plunger (4) drives the Z type and colludes plate (7) upward movement, thereby, when need put down weight, open Dump valve (6) and get final product weight jack-up.
