Embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Piston as shown in Figures 2 and 4, comprises piston head 1, connecting rod 4 and rotating shaft 2, and one end of connecting rod 4 offers through hole, and is movably set in rotating shaft 2 by this through hole, rotating shaft 2 axially and connecting rod 4 axial vertical.For guaranteeing that connecting rod 4 can rotate and slide with respect to rotating shaft 2 in the course of the work, coordinating between through hole and rotating shaft 2 is Spielpassung.It should be noted that, for preventing connecting rod 4 axis hole wearing and tearing, bearing also can be set in axis hole, connecting rod 4 coordinates with rotating shaft 2 by bearing.In this embodiment, piston head 1 is fixedly connected with by link 3 with rotating shaft 2, rotating shaft 2 axially and piston head 1 axial vertical, while adopting this Placement, piston head can not rotate and slide with respect to rotating shaft 2.
It should be noted that, in technique scheme, according to the difference of piston purposes, on piston head 1, rubber material can be set, oil ring and compression ring etc. also can be set, do not do concrete restriction at this.
In technique scheme, link 3 can be bolt, and rotating shaft 2 is provided with attachment hole, and attachment hole quantity is multiple for can be, and is preferably two, is placed in respectively the two ends, left and right of rotating shaft 2.For convenience of offering of attachment hole, the place of offering attachment hole in rotating shaft 2 can be flat.
Correspondingly, a side of piston head 1 is provided with the bolt hole corresponding with attachment hole.When assembling, first connecting rod 4 is sheathed in rotating shaft 2, then is screwed onto in the bolt hole of piston head 1 after passing the attachment hole of rotating shaft 2 with link 3, thereby realize being connected of connecting rod 4 and piston head 1.Above-mentioned link 3 can be also the conventional links such as rivet.
