Abstract

The utility model relates to an oil cylinder, and particularly relates to a guide oil cylinder internally provided with a guide rod. The guide oil cylinder internally provided with the guide rod comprises a cylinder barrel, wherein a piston is arranged inside the cylinder barrel; and a piston rod is connected with the piston. The guide oil cylinder is characterized in that the guide rod is arranged inside the cylinder barrel, and passes through the piston; the part of the guide rod, which passes through the piston, entirely stretches into the inside of the piston; the piston can slide along the guide rod; and the upper end and the lower end of the guide rod are respectively fixedly connected with the top and the bottom of the cylinder barrel. The oil cylinder disclosed by the utility model has the beneficial effects that the piston rod is effectively prevented from rotating in the working process of a hydraulic oil cylinder, so that the normal working of the piston rod is ensured; the oil cylinder has the advantages of simple structure, convenience in mounting, low cost and ideal effect; the working performance of the hydraulic oil cylinder can be ensured; and the service life of the hydraulic oil cylinder is prolonged.

Description

Establish the guiding oil cylinder of guide rod in a kind of

(1) technical field

The utility model relates to a kind of oil cylinder, establishes the guiding oil cylinder of guide rod in particularly a kind of.

(2) background technique

At present, the hydraulic jack utmost point is widely used in all trades and professions, and common hydraulic jack is when expanding-contracting action, because load over centre, circumference cooperates unequal reason, can produce certain rotation when causing the piston rod action, has produced the straight line motion that rotates compound.When owing to need of work, piston rod is not connect constraint during the piston rod installation, but need to export when not attaching the straight line motion that rotates accurately, the anti-rotation of piston rod just becomes very important.Yet, in the prior art, the anti-rotation most complex structure of mechanism in the hydraulic jack, working life is short, inconvenience is installed, and anti-rotation effect is undesirable, and cost is higher.

(3) summary of the invention

The utility model is in order to remedy the deficiencies in the prior art, provide a kind of simple in structure, easy for installation, long service life, low, the anti-rotation effect of cost good in establish the guiding oil cylinder of guide rod.

The utility model is achieved by the following technical solution:

Establish the guiding oil cylinder of guide rod in a kind of, comprise cylinder barrel, be provided with piston in the cylinder barrel, piston is connected with piston rod, it is characterized in that: be provided with a guide rod in the described cylinder barrel, guide rod passes piston, and the part of passing piston on the guide rod stretches into internal piston fully, piston can slide along guide rod, and guide rod up and down two ends is fixedly connected with top and the bottom of cylinder barrel respectively.

The beneficial effects of the utility model are: prevented the rotation of piston rod in the hydraulic jack working procedure effectively, guaranteed the proper functioning of piston rod; Simple in structure, easy for installation, cost is low, satisfactory for result, guaranteed the service behaviour of hydraulic jack, prolonged the working life of hydraulic jack.

(4) description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing 1 is main TV structure schematic representation of the present utility model;

Accompanying drawing 2 is plan structure schematic representation of the present utility model;

Among the figure, 1 cylinder barrel, 2 pistons, 3 piston rods, 4 guide rods.

(5) embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises cylinder barrel 1, be provided with piston 2 in the cylinder barrel 1, piston 2 is connected with piston rod 3, be provided with a guide rod 4 in the cylinder barrel 1, guide rod 4 passes piston 2, the part of passing piston 2 on the guide rod 4 stretches into piston 2 inside fully, and piston 2 can slide along guide rod 4, and guide rod is fixedly connected with top and the bottom of cylinder barrel 1 respectively at two ends about in the of 4.

Adopt the guiding oil cylinder of establishing guide rod in a kind of of the present utility model, by a guide rod 4 piston 2 and cylinder barrel 1 are fixed together, thereby connect constraint for 3 one in piston rod, avoided the hydraulic jack relative movement between piston 2 and the cylinder barrel 1 in the course of the work, thereby guaranteed relative movement can not take place between piston rod 3 and the cylinder barrel 1, namely guarantee the piston rod 3 output straight line motion of subsidiary rotation accurately constantly, simple in structure, easy for installation, cost is low, satisfactory for result, guarantee the service behaviour of hydraulic jack, prolonged the working life of hydraulic jack.

Claims (1)

1. establish the guiding oil cylinder of guide rod in one kind, comprise cylinder barrel (1), be provided with piston (2) in the cylinder barrel (1), piston (2) is connected with piston rod (3), it is characterized in that: be provided with a guide rod (4) in the described cylinder barrel (1), guide rod (4) passes piston (2), the part of passing piston (2) on the guide rod (4) stretches into piston (2) inside fully, piston (2) can slide along guide rod (4), and guide rod (4) two ends up and down is fixedly connected with top and the bottom of cylinder barrel (1) respectively.
