The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of oil cylinder oil cylinder front cover of easy to process, reasonable in design.
The purpose of this utility model realizes by following technical proposal:
A kind of oil cylinder front cover, comprise tubular upper cover body and tubular lower cover, described upper cover body docks setting mutually with lower cover, it is characterized in that, seal ring one is provided with in described lower cover, described lower cover upper end is provided with interior ring-shaped step, and be provided with the guide ring for playing the guiding role to piston rod in described interior ring-shaped step, described upper cover body and lower cover are fixed together by linkage structure.Due to upper cover body and lower cover are adopted split-type structural design, be provided with interior ring-shaped step in the upper end of lower cover, guide ring be installed in interior ring-shaped step, can leading role be played, facilitate again the processing of internal ring-shaped step.During installation, first guide ring is encased in interior ring-shaped step, then upper cover body is encased in the top of lower cover, finally by linkage structure, upper cover body and lower cover are fixed together, effectively guide ring are fixed, the good stability of guide ring.
In above-mentioned oil cylinder front cover, described linkage structure comprises the Elastic buckle with upper limit portion and lower limit portion, and the inner side in described upper limit portion is resisted against the upper end portion of upper cover body, and the inner side in described lower limit portion is resisted against on the underpart of lower end cap.
In above-mentioned oil cylinder front cover, described Elastic buckle is three and is uniformly distributed.
In above-mentioned oil cylinder front cover, the upper end portion of described upper cover body has the radial groove one be equipped with upper limit portion, and its sidepiece has the axial groove one be equipped with Elastic buckle upper part; The underpart of described lower cover has the radial groove two be equipped with lower limit portion, and its sidepiece has the axial groove two be equipped with Elastic buckle lower part; Described upper limit portion is positioned at radial groove one, and described lower limit portion is positioned at radial groove two, and described Elastic buckle is with in axial groove one and axial groove two simultaneously.
In above-mentioned oil cylinder front cover, the distance between described radial groove one to radial groove two is slightly larger than the distance between described upper limit portion to lower limit portion.
Under the effect of this Elastic buckle, effectively upper cover body and lower cover can be linked together, because the distance between radial groove one to radial groove two is slightly larger than the distance between upper limit portion to lower limit portion, so basic slitless connection between upper cover body and lower cover, also can improve the sealing of this oil cylinder front cover.
In above-mentioned oil cylinder front cover, in described upper cover body, be provided with seal ring two.The seal ring two that this place is arranged can further improve the sealing of oil cylinder front cover.
Compared with prior art, this oil cylinder front cover has the following advantages:
Adopt split-type structural to design oil cylinder front cover, be provided with interior ring-shaped step in the upper end of lower cover, convenient processing, then by ring-shaped step in guide ring mounting groove, compressed by upper end cap, effectively can ensure the stability of guide ring; In lower cover, establish seal ring one and in upper cover body, establish seal ring two, playing dual seal action, good airproof performance.
