Abstract
The utility model relates to a kind of hydraulic jack sectionalized piston, and comprise piston body, piston body is provided with endoporus, it is characterized in that: piston body is made up of multiple merogenesis piston body vertically, crosses tongue and groove and connect location between merogenesis piston body; Between merogenesis piston body, in corresponding piston body, hole site is provided with seal ring; The outside of the merogenesis piston body at middle part is provided with oil seal groove.
Description
Technical field
The utility model relates to a kind of hydraulic jack sectionalized piston.
Background technique
The boom cylinder hydraulic oil of the engineering machinery such as excavator, loader, hoist is inner easily to be revealed, often need installation and removal pistons work seal element, but the piston due to existing hydraulic jack is all all-in-one-piece, when assembling and maintenance, install and change primary seal and the sealing of Y type is all very difficult, and also easily damaging new seal in installation process.
Model utility content
Goal of the invention of the present utility model is to provide a kind of hydraulic jack sectionalized piston, facilitates installation and the replacing of piston seal.
Realize the technological scheme of the present utility model object:
A kind of hydraulic jack sectionalized piston, comprise piston body, piston body is provided with endoporus, it is characterized in that: piston body is made up of multiple merogenesis piston body vertically, crosses tongue and groove and connect location between merogenesis piston body; Between merogenesis piston body, in corresponding piston body, hole site is provided with seal ring; The outside of the merogenesis piston body at middle part is provided with oil seal groove.
Each merogenesis piston body is symmetrical arranged up and down.
The outside oil seal groove of the merogenesis piston body at middle part is U-shaped or Y shape oil seal groove.
The seal ring of piston body endoporus is ○-shaped seal ring.
The beneficial effect that the utility model has:
The utility model piston body is made up of multiple merogenesis piston body vertically, during installation and removal, each merogenesis piston body can be inserted in successively or depart from piston rod, more convenient to install and dismounting, thus facilitates installation and the replacing of piston seal.Because piston body is made up of multiple merogenesis piston body, can according to cylinder efficient needs, the quantity of adjustment merogenesis piston body, thus the number of adjustment oil seal groove and U-shaped seal the number of (primary seal), Y shape sealing.Between the utility model merogenesis piston body, in corresponding piston body, hole site is provided with seal ring, effectively can solve the problem of hydraulic oil internal leakage.The each merogenesis piston body of the utility model is symmetrical arranged up and down, can replace mutually, more convenient to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, piston body is made up of multiple merogenesis piston body 1 vertically, and cross tongue and groove between merogenesis piston body and connect location, each merogenesis piston body is symmetrical arranged up and down.Between merogenesis piston body, in corresponding piston body, hole site is provided with ○-shaped seal ring, piston body endoporus is corresponding has zero shape seal groove 2, the outside of the merogenesis piston body at middle part is provided with oil seal groove 3, oil seal groove 3 is U-shaped or Y shape oil seal groove, corresponding primary seal or Y shape sealing, the outside of the top and bottom merogenesis piston body has scarfing cinder annular groove 6 and guiding annular groove 7.
During installation, first seal element is arranged on corresponding merogenesis piston body, then merogenesis piston body is bottom fixed the neck at piston rod 4, each merogenesis piston body is inserted in piston rod 4 from the bottom to top successively, and located by tongue and groove, tailpiece of the piston rod head nut 5 passes through merogenesis piston body topmost by fastening for whole piston body, thus piston body and piston rod 4 is connected and fixed.Can according to cylinder efficient needs, the quantity of adjustment merogenesis piston body, thus the number of the number of adjustment oil seal groove and U-shaped (primary seal), Y shape sealing.
