Circle, for the first annular slot position between the convex disk and the fixation hole, which is equipped with the to the convex disk sunken inside
Second ring slot is embedded with the second sealing ring for protruding from the convex disk outside wall surface in second annular groove.
In hydraulic cylinder sealing end cap described in the utility model, every reinforcing rib first end is equal in the plural number reinforcing rib
It is directed toward at the center location of the lid, the angle in the plural number reinforcing rib between every adjacent two reinforcing ribs is equal.
In hydraulic cylinder sealing end cap described in the utility model, which is fixedly connected with the lid, this is convex
Disk second end end face is equipped with to the concave surface of the convex disk sunken inside, which extends to the convex disk periphery.
In hydraulic cylinder sealing end cap described in the utility model, which is in bowl structure.
In hydraulic cylinder sealing end cap described in the utility model, which is equipped with and protrudes from second face of flange
First arc bump, first arc bump are equipped with the first through hole for vertically running through first arc bump, the flange bottom
End is equipped with the second arc bump for protruding from second face of flange, which, which is equipped with, vertically runs through second arc
Second through hole of convex block.
The hydraulic cylinder sealing end cap for implementing the utility model, has the advantages that using the hydraulic of the utility model
When cylinder end cover, when end cap is covered on cylinder ends, convex disk can be sealed and be inserted into hydraulic cylinder, until flange and liquid
Cylinder pressure end face abuts, and then passes through fixation hole using bolt and is spirally connected later with hydraulic cylinder end face, realizes the fixation to end cap.Into one
Step, by the way that the second sealing ring is arranged in convex disk outside wall surface, by the way that the first sealing ring is arranged in flange inner face, by end cap lid
When set on cylinder ends, the first sealing ring is sealed against between flange and hydraulic cylinder end face, and the second sealing ring seals against
Between convex disk outside wall surface and hydraulic cylinder inner wall, dual-seal is formed, sealing effect is played.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is the structural schematic diagram of the utility model hydraulic cylinder sealing end cap.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
As shown in Figure 1, the end cap 1 includes discoid in the hydraulic cylinder sealing end cap first embodiment of the utility model
Lid 2, the plural article reinforcing rib 3 for being fixedly arranged on 2 first face of lid are fixedly arranged on 2 second face of lid and protrude from the lid 2 the
The discoid convex disk 4 in two faces, 2 diameter of lid are greater than convex 4 diameter of disk, which protrudes from convex 4 periphery of disk and formed
Annular flange 5, the flange 5 are equipped at least two fixation holes 6 for running through the flange 5, which is equipped with convex to this
The first annular slot 7 of 5 sunken inside of edge is embedded with the first sealing for protruding from the 5 medial surface surface of flange in the first annular slot 7
Circle 8, which is located between the convex disk 4 and the fixation hole 6, which is equipped with to convex 4 indent of disk
The second sunken annular groove 9 is embedded with the second sealing ring 10 for protruding from convex 4 outside wall surface of disk in second annular groove 9.
Using the utility model hydraulic cylinder sealing end cap 1 when, can be by convex disk 4 when end cap 1 is covered on cylinder ends
Sealing is inserted into hydraulic cylinder, until flange 5 is abutted with hydraulic cylinder end face, then uses bolt after fixation hole 6 and liquid
Cylinder pressure end face is spirally connected, and realizes the fixation to end cap 1.Further, by the way that the second sealing ring 10 is arranged in convex 4 outside wall surface of disk, lead to
It crosses and the first sealing ring 8 is set in 5 medial surface of flange, when end cap 1 is covered on cylinder ends, the sealing of the first sealing ring 8 is supported
Be connected between flange 5 and hydraulic cylinder end face, the second sealing ring 10 seal against in convex 4 outside wall surface of disk and hydraulic cylinder inner wall it
Between, dual-seal is formed, sealing effect is played.
Specifically, every 3 first end of reinforcing rib is directed at the center location of the lid 2 in the plural number reinforcing rib 3, it should
Angle in plural reinforcing rib 3 between every adjacent two reinforcing ribs 3 is equal.
Further, which is fixedly connected with the lid 2, which is equipped with to the convex disk
The concave surface 11 of 4 sunken insides, 11 periphery of concave surface extend to convex 4 periphery of disk.Specifically, the concave surface 11 is in bowl structure.Convex
When 4 second end of disk is squeezed by highly pressurised liquid, concave surface 11 by outwardly against tension so that 4 second end of convex disk be tightly attached to it is hydraulic
The inside wall of cylinder forms certain sealing effect.
Further, it is more fastened to connect end cap 1 with hydraulic cylinder first end, which is equipped with and protrudes from
