Abstract
The utility model relates to a cylinder piston which comprises a piston and a piston rod, wherein the piston rod is connected with the piston; a disc is arranged at an end of the piston rod; the piston rod is vertically connected with a central part of the disc; a circular slot which has a radius as same as the radius of the disc is arranged on the piston corresponding to the disc of the piston rod; a sealing groove is arranged in the circular slot; and the disc is arranged in the circular slot. The disc is arranged at the end of the piston rod, the circular slot is arranged on the piston corresponding to the disc and is connected through a screw, and a sealing ring is arranged at a joint of the disc and the circular slot, so that the mounting and dismounting are conveniently carried out, the sealing property of the piston is greatly increased and the whole property of the cylinder is promoted.
Description
Technical field
The utility model relates to the cylinder field, relates in particular to a kind of cylinder piston.
Background technique
Cylinder is a kind of pneumatic apparatus, common cylinder comprises the parts such as cylinder body, piston, piston rod first, wherein the performance of cylinder piston is the core of whole cylinder, in the prior art, piston and piston rod directly pass connection, middlely stop gas leakage by seal ring, but after working long hours, the seal ring performance reduces, and directly causes the cylinder overall performance to reduce, thus the cost of idleness resource.
The model utility content
In view of this, be necessary the cylinder piston that provides a kind of tightness good and simple in structure.
The utility model is to realize 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 the described circular groove.
Further, described disk is screwed in the described circular groove.
Further, be provided with seal ring between described disk and the circular groove, described seal ring is located in the 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 the cylinder piston that the utility model provides is: by at piston rod end disk being set, the place arranges circular groove at the corresponding disk of piston, link to each other by screw, 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.
