Abstract
The utility model relates to the technical field of pistons, in particular to an anti-revolution piston which comprises a polygonal column-shaped piston rod and a piston piece. The anti-revolution piston adopts a polygonal column-shaped piston rod, wherein the anti-torsion capacity of the piston rod is strong so that the piston rod can effectively be prevented from revolving when pressed and the usage effect is good.
Description
Technical field
The utility model relates to the piston technical field, refers in particular to a kind of rotation inhibiting piston.
Background technique
Existing piston, its piston rod generally is that employing is cylindrical, no matter be integral structure or fabricated structure, all there is the problem of rotating of can't preventing in the cylindrical piston of this piston rod, the torsional rotation force of piston rod is less, thereby be easy to the situation that piston rod gets loose occur, affect the use of product.
Therefore, based on the defective of above-mentioned existing piston, need to improve existing piston.
The model utility content
The purpose of this utility model is to provide a kind of rotation inhibiting piston for the deficiencies in the prior art, and it is existing that this rotation inhibiting piston has solved existing piston: the torsional rotation force of piston rod is less to be easy to occur the defective that piston rod gets loose.
For achieving the above object, the utility model is achieved through the following technical solutions:
The rotation inhibiting piston comprises piston rod, piston sheet, and piston rod is the polygonal cylinder.
Described piston sheet has sleeve joint hole, and piston rod inserts in the sleeve joint hole and is fixed together with piston sheet.
Described piston sheet is rounded.
Described piston rod is the quadrilateral cylinder.
Described piston rod and piston sheet are the integral type structure.
The beneficial effects of the utility model are: because the employing piston rod is the design of polygonal cylinder, the twisting resistance of piston rod is larger, can effectively prevent the stressed generation rotation of piston rod, and using effect is better.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Seeing Fig. 1---Fig. 2, the utility model rotation inhibiting piston comprises: piston rod 11, piston sheet 12, sleeve joint hole 13, cylinder 14.
The rotation inhibiting piston comprises piston rod 11, piston sheet 12, and piston rod 11 is the polygonal cylinder, because piston rod 11 is polygonal cylinders, so the twisting resistance of piston rod 11 is larger, can effectively prevent piston rod 11 stressed generation rotations, and using effect is better.
Wherein, described piston sheet 12 is rounded.
Concrete, piston rod 11 is polygonals, can be that described piston rod 11 is the quadrilateral cylinder, also can be pentagon or Hexagon etc., and is unrestricted.
More specifically, described piston sheet 12 has sleeve joint hole 13, and piston rod 11 inserts in the sleeve joint hole 13 and is fixed together with piston sheet 12, and piston sheet 12 adopts knockdown structure with piston rod 11.
In addition, described piston rod 11 can also be integral structure with piston sheet 12, and namely adding man-hour piston rod 11 is one with piston sheet 12.
Fig. 2 is the schematic representation that the utility model is applied to cylinder 14.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, and unrestricted the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
Claims (5)
1. rotation inhibiting piston, it is characterized in that: comprise piston rod, piston sheet, piston rod is the polygonal cylinder.
