Abstract
The invention relates to an air cylinder piston. The air cylinder piston comprises a piston body and a piston rod. The piston rod is connected with the piston body. A disc is arranged at one end of the piston rod. The piston rod is perpendicularly connected to the center position of the disc. A circular groove with the radius identical to that of the disc is formed in the position, corresponding to the disc of the piston rod, of the piston body. A sealing ring groove is formed inside the circular groove. The disc is arranged in the circular groove. The disc is arranged at one end of the piston rod, the circular groove is formed in the position, corresponding to the disc, of the piston body, the disc and the circular groove are connected through a screw, and a sealing ring is arranged on the connecting portion of the disc and the circular groove, so that assembly and disassembly are convenient, the sealing performance of the piston is greatly improved, and therefore the overall performance of an air cylinder is improved.
Description
Technical field
The present invention relates to cylinder field, relate in particular to a kind of cylinder piston.
Background technique
Cylinder is a kind of pneumatic apparatus, first common cylinder comprises the parts such as cylinder body, piston, piston rod, wherein the performance of cylinder piston is the core of whole cylinder, in prior art, piston is with piston rod directly through being connected, and centre stops gas leakage by seal ring, but after working long hours, seal ring performance reduces, and directly causes cylinder overall performance to reduce, thus cost of idleness resource.
Summary of the invention
In view of this, be necessary the cylinder piston that provides a kind of tightness good and simple in structure.
The present invention realizes like this, a kind of cylinder piston, comprise piston and piston rod, described piston rod is connected with described piston, the termination of described piston rod is provided with disk, and described piston rod is vertically connected on the center portion of described disk, and the disk place of the corresponding described piston rod of described piston is provided with the circular groove identical with described disc radius, described circular groove inside is provided with seal groove, and described disk is located in described circular groove.
Further, described disk is screwed in described circular groove.
Further, between described disk and circular groove, be provided with seal ring, described seal ring is located in described seal groove.
Further, described piston edge is provided with seal groove two.
Further, described disk and described piston rod are integrated and form.
The advantage of cylinder piston provided by the invention is: by disk being set at piston rod end, at the corresponding disk of piston, place arranges circular groove, by screw, be connected, and be provided with seal ring at disk and circular groove joint, be easy for installation and removal, and greatly improved the sealability of piston, thereby improved the overall performance of cylinder.
Accompanying drawing explanation
Fig. 1 is the structural representation of cylinder piston of the present invention.
Fig. 2 is the structural representation of the piston in Fig. 1.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
See also Fig. 1 and Fig. 2, the structural representation that wherein Fig. 1 is cylinder piston of the present invention, Fig. 2 is the structural representation of the piston in Fig. 1.
Described cylinder piston 10 comprises piston 2 and piston rod 1, described piston rod 1 is connected with described piston 2, the termination of described piston rod 1 is provided with disk 3, described piston rod 1 is vertically connected on the center portion of described disk 3, disk 3 places of the corresponding described piston rod 1 of described piston 2 are provided with the circular groove 6 identical with described disk 3 radiuses, described circular groove 6 inside are provided with seal groove 7, and described disk 3 is located in described circular groove 6.
Described disk 3 is screwed in described circular groove 6, between described disk 3 and circular groove 6, be provided with seal ring 4, described seal ring 4 is located in described seal groove 7, and described piston 2 edges are provided with seal groove 25, and described disk 3 and described piston rod 1 are integrated and form.
In sum, by piston rod end, disk being set, at the corresponding disk of piston, place arranges circular groove, by screw, be connected, and be provided with seal ring at disk and circular groove joint, be easy for installation and removal, and greatly improved the sealability of piston, thereby improved the overall performance of cylinder.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
