Abstract
The utility model relates to an improved piston, which comprises a piston body and a piston cavity. The piston cavity arranged inside the piston body is used for being installed with a piston rod. The cross section of the piston cavity is conical. According to the improved piston, the piston cavity is conical. Therefore, compared with a conventional cylindrical cavity, the piston body is forced to move while the movement distance of a piston rod arranged inside the piston cavity is reduced. The improved piston is suitable for occasions with a relatively small movement space and also has the advantages of simple structure, practicality and low manufacture cost.
Description
Technical field
The utility model relates to a kind of piston, refers to the improved piston that a kind of free gap is little especially, belongs to the hydraulic equipment technical field.
Background technique
Along with science and technology development, piston is widely used in the various engineering equipment more, and common piston comprises piston only; The set inside of said piston only has piston cavity, and said piston cavity is used for installing piston rod; Said piston cavity is arranged to cylinder type, the piston of this structure, and when the piston rod bottom of piston cavity on earth, piston only could stressed work, because work distance is big, only adapts to the big occasion of working space, and the situation little to working space then is difficult to use.
The model utility content
The utility model purpose is to provide a kind of free gap little improved piston for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of improved piston comprises piston only, piston cavity; Said piston cavity is arranged in the piston only, is used for installing piston rod; The cross section of said piston cavity is conical.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The improved piston of the utility model, said piston cavity is arranged to taper shape, within it piston rod is installed is like this compared original cylinder type cavity and can reduce displacement distance, can make the stressed motion of piston only, is fit to the little occasion in free gap; This programme is simple in structure, practical, low cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the sectional view of the piston of the utility model;
Wherein: 1, piston only; 2, piston cavity.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of improved piston of the utility model shown in accompanying drawing 1 comprises piston only 1, piston cavity 2; Said piston cavity 2 is arranged in the piston only 1, is used for installing the piston rod (not shown); The cross section of said piston cavity 2 is conical.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The improved piston of the utility model, said piston cavity is arranged to taper shape, within it piston rod is installed is like this compared original cylinder type cavity and can reduce displacement distance, can make the stressed motion of piston only, is fit to the little occasion in free gap; This programme is simple in structure, practical, low cost of manufacture.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation, all employing equivalents or equivalence replacement and the technological scheme that forms all drops within the utility model rights protection scope.
