The utility model relates to a base plate installation structure of a hydraulic oil cylinder. The base plate installation structure of the hydraulic oil cylinder comprises a cylinder body base tube and a base plate which are coaxial, the base plate is located on the lower portion of the cylinder body base tube so as to seal a lower end opening of the cylinder body base tube, a base plate flanging extending along the axis of the base plate is arranged on the periphery of the base plate, the outer wall of the base plate flanging is attached to the inner wall of the base tube, annular sealing grooves are formed in the circumference of the base plate flanging, and sealing rings are embedded into the annular sealing grooves so as to enable the cylinder body base tube and the base plate to be sealed. Inner snap spring grooves are formed in the inner wall of the lower end opening of the cylinder body base tube, outer snap spring grooves corresponding to the inner snap spring grooves are formed in the lower portion of the outer wall of the base plate flanging, and snap springs are clamped between the inner snap spring grooves and the outer snap spring grooves to fix the base plate axially. A plurality of rib plates connecting the center of the base plate and the base plate flanging are arranged on the lower end face of the base plate, and the rib plates are distributed in a radial mode with the axis of the base plate as the center. A screw hole extending along the axis of the base plate is formed in the center of the lower end face of the base plate. The base plate installation structure of the hydraulic oil cylinder is simple in structure and convenient to install.
Description
Technical field
The utility model relates to a kind of hydraulic jack, particularly a kind of installing structure of bottom plate of hydraulic jack.
Background technique
In prior art, the installing structure of bottom plate of hydraulic jack comprises cylinder body base cylinder and the base plate of coaxial line, base plate is positioned at cylinder body base cylinder bottom cylinder body base cylinder lower end mouth is sealed, the inwall of the periphery of base plate and base cylinder fits, the excircle of base plate is provided with annular seal groove, is embedded with seal ring and makes to realize and sealing between cylinder body base cylinder and base plate in annular seal groove.The lower end mouth inwall of cylinder body base cylinder is provided with annular recess, is embedded with crescent shape jam plate in annular recess, and described jam plate is supported on the bottom of base plate, and screw in the screw hole through jam plate screw-in base plate is fixed base plate and jam plate from bottom to top.This installing structure of bottom plate more complicated, needs to attack screw hole on base plate, conventionally need to adopt steel part to make, and accuracy of manufacturing requires higher, installs and also relatively wastes time and energy.
Model utility content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of installing structure of bottom plate of hydraulic jack is provided, simple in structure, easy for installation.
For solving above technical problem, the installing structure of bottom plate of a kind of hydraulic jack of the present utility model, comprise cylinder body base cylinder and the base plate of coaxial line, described base plate is positioned at cylinder body base cylinder bottom cylinder body base cylinder lower end mouth is sealed, the periphery of described base plate is provided with the base plate flange along base plate Axis Extension, the inwall of the outer wall of described base plate flange and described base cylinder fits, the circumference of described base plate flange is provided with annular seal groove, is embedded with seal ring and makes to realize and sealing between cylinder body base cylinder and base plate in described annular seal groove; The lower end mouth inwall of described cylinder body base cylinder is provided with interior jump-ring slot, and the outer wall bottom of described base plate flange is provided with the outer jump-ring slot corresponding with interior jump-ring slot, and jump ring is stuck between described interior jump-ring slot and interior jump-ring slot base plate axial restraint.
With respect to prior art, the utility model has been obtained following beneficial effect: on base plate without attacking screw hole, also without fixing by screw, can adopt foundry goods, cost of production is low and be convenient to processing, after base plate is in place, can make base plate axially locating as long as jump ring is installed.
As preferred version of the present utility model, the lower end surface of described base plate is provided with the gusset of multiple tracks connecting bottom board center and base plate flange, and each described gusset radially distributes centered by base plate axis.Employing gusset can improve the intensity of base plate, reduces the thickness of base plate body, and weight reduction, saves material, reduces production costs.
As preferred version of the present utility model, the center, lower end surface of described base plate is provided with along the screw hole of base plate Axis Extension.Base plate center arranges screw hole, can be screwed into screw and be convenient to assembling or the dismounting of base plate.
