Abstract
The present invention announces a kind of splicing self seal hydraulic cylinder barrel, belongs to hydraulic cylinder technical field.Including cylinder barrel and cylinder cap；It is characterized in that：Described cylinder cap one end is provided with a circle deep gouge, and the deep gouge inwall both sides are provided with internal thread, and cylinder barrel end inside and outside wall is had in external screw thread, cylinder barrel precession cylinder cap deep gouge；Inside and outside wall has step-like seam at the cylinder cap deep gouge opening, and cylinder barrel end inside and outside wall is respectively equipped with the shelves platform being engaged with the step-like seam of cylinder cap；Exterior seal ring and inner seal ring are separately installed between the step-like seam of the cylinder cap and cylinder barrel shelves platform.Simple in construction, good sealing effect of the invention, it is easy to use, substantially increase the operating efficiency and service life of oil cylinder.
Description
Technical field
It is specifically a kind of splicing self seal hydraulic cylinder barrel the present invention relates to hydraulic cylinder technical field.
Background technology
The cylinder barrel of hydraulic jack is typically all to be attached using connected modes such as gland, internal jump ring, bolts with cylinder cap
, the sealing of these connected modes is unable to thoroughly be ensured, when in use between it is long after, easily let out
Leakage, greatly reduces its operating efficiency.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of splicing self seal hydraulic cylinder barrel.
The present invention is achieved through the following technical solutions：One kind splicing self seal hydraulic cylinder barrel, including cylinder barrel and cylinder cap；Its
It is characterised by：Described cylinder cap one end is provided with a circle deep gouge, and the deep gouge inwall both sides are provided with internal thread, the cylinder barrel end
Inside and outside wall is had in external screw thread, cylinder barrel precession cylinder cap deep gouge；Inside and outside wall has step at the cylinder cap deep gouge opening
Shape seam, cylinder barrel end inside and outside wall is respectively equipped with the shelves platform being engaged with the step-like seam of cylinder cap；In the cylinder cap step
Exterior seal ring and inner seal ring are separately installed between shape seam and cylinder barrel shelves platform.
The cylinder barrel is seamless steel pipe.
Compared with prior art, the beneficial effects of the invention are as follows：Simple in construction, good sealing effect of the invention, user
Just, the operating efficiency and service life of oil cylinder are substantially increased.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1st, cylinder barrel；2nd, cylinder cap；2-1, deep gouge；3rd, exterior seal ring；4th, inner seal ring.
Embodiment
The following is the specific embodiment of the present invention, in conjunction with accompanying drawing, the present invention will be further described.
As shown in figure 1, a kind of splicing self seal hydraulic cylinder barrel, including cylinder barrel 1 and cylinder cap 2；Described one end of cylinder cap 2 is provided with
One circle deep gouge 2-1, the deep gouge 2-1 inwalls both sides are provided with internal thread, and the end inside and outside wall of cylinder barrel 1 has outer spiral shell
In line, the deep gouge 2-1 of 1 precession cylinder cap of cylinder barrel 2；Inside and outside wall has step-like seam, institute at the deep gouge 2-1 openings of cylinder cap 2
State the end inside and outside wall of cylinder barrel 1 and be respectively equipped with the shelves platform being engaged with the step-like seam of cylinder cap 2；In the step-like seam of the cylinder cap 2
Exterior seal ring 3 and inner seal ring 4 are separately installed between 1 grade of platform of cylinder barrel.The cylinder barrel 1 is seamless steel pipe.
The cylinder structure of present embodiment causes it more preferably good with the sealing effectiveness that cylinder cap coordinates, and can more cause oil cylinder
Stably work, using effect is good.Present embodiment is simple in construction, good sealing effect, easy to use, substantially increases oil
The operating efficiency and service life of cylinder.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
