Abstract
The utility model discloses a piston rod nut for an oil-pressure air cylinder provided with a limiting mechanism. The piston rod nut comprises a piston rod nut body, and is characterized in that the piston rod nut further comprises a limiting hole and a limiting pillar, wherein the limiting hole is formed in the side face of the piston rod nut body; and the limiting pillar is mounted in the limiting hole. According to the piston rod nut for the oil-pressure air cylinder, the limiting hole is formed in the side face of the piston rod nut for the oil-pressure air cylinder; when piston rod threads of the oil-pressure air cylinder are tightened on a piston rod of the oil-pressure air cylinder, the limiting pillar is inserted into the limiting hole, and the loosening of the threads can be prevented effectively; and the piston rod nut for the oil-pressure air cylinder is simple in structure, and very practical.

Background technique
Injection machine has another name called injection molding machine or injector.It is to utilize the plastic shaping grinding tool to make the main forming equipment of the plastic article of various shapes thermoplastic or thermosetting property material.Be divided into vertical, horizontal, all electric.Injection moulding function heating of plastic applies high pressure to molten plastic, makes its ejaculation be full of mold cavity.
Piston rod as its name suggests, is the connected element of supporting piston acting, and major applications is move frequent, the higher moving element of technical requirements in oil cylinder, cylinder.
Piston rod is fixed on the injection machine by piston rod nut, existing oil pressure cylinder piston rod nut is located on the outside thread of oil pressure cylinder piston rod by inner screw sheath, under the state of normal operation, working long hours to cause thread looseness, seriously then can scuffing of cylinder bore, the damage board.
Therefore, special standby a kind of oil pressure cylinder piston rod nut with position-limit mechanism that needs is to solve problems of the prior art.
The model utility content
The purpose of this utility model is that piston rod nut is installed in the defective of easily becoming flexible on the piston rod in the prior art in order to solve, and provides the oil pressure cylinder piston rod nut with position-limit mechanism to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
Have the oil pressure cylinder piston rod nut of position-limit mechanism, comprise the piston rod nut body, it is characterized in that, also comprise spacing hole, limited post, described spacing hole is arranged on the side of piston rod nut body, and described limited post is installed in the spacing hole.
In the utility model, described spacing hole is a tapped hole, and described limited post is a screw.
In the utility model, described screw comprises the intrinsic insertion end of insertion piston rod nut and the exposed end that exposes in the outside, and described insertion end is a plane.
In the utility model, described screw comprises the intrinsic insertion end of insertion piston rod nut and the exposed end that exposes in the outside, and described insertion end is the sharp face of a taper.
In the utility model, described spacing hole is a unthreaded hole, and described limited post is a nail.
The utlity model has the oil pressure cylinder piston rod nut of position-limit mechanism, compared with prior art, in oil pressure cylinder piston rod nut side spacing hole is set, when making the oil pressure cylinder piston rod thread be tightened on the oil pressure cylinder piston rod, insert limited post at spacing hole, just can effectively prevent the loosening, simple in structure of screw thread, very practical, realize the purpose of this utility model.
