Abstract

The utility model discloses a kind of double rod type hydraulic cylinders, piston rod passes through cylinder barrel, section connect cylinder cap with cylinder cap and connect with gland and fixed by attachment screw before and after cylinder barrel, and piston is equipped in cylinder barrel, and piston is connect with taper pin, this hydraulic cylinder structure is simple, buffer unit is arranged in hydraulic cylinder both ends, and cushioning principle is when piston is in cylinder cap, and increase has resistance, to reduce the movement velocity of piston, to avoid piston slap cylinder cap.

Description

A kind of double rod type hydraulic cylinder
Technical field
The utility model relates to the technical field of hydraulic cylinder more particularly to a kind of double rod type hydraulic cylinders.
Background technique
In order to avoid piston hits cylinder cap at stroke both ends, noise is generated, damages body, we are arranged at hydraulic cylinder both ends Buffer unit, cushioning principle are when piston is in cylinder cap, and increase has resistance, to reduce the movement velocity of piston, to avoid Piston slap cylinder cap.
Utility model content
Purpose of utility model: the utility model solves the technical issues of above-mentioned background technique proposition, and the utility model mentions For a kind of double rod type hydraulic cylinder.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of double rod type hydraulic cylinder, including Piston rod, gland, cylinder cap, sealing ring, cylinder barrel, piston, piston channel, dashpot, taper pin, attachment screw, the piston rod are worn Cylinder barrel is crossed, section is connect with cylinder cap before and after the cylinder barrel, and the cylinder cap connect with gland and fixed by attachment screw, in the cylinder barrel Equipped with piston, the piston is connect with taper pin.
Further, the piston rod passes through the piston in cylinder barrel.
Further, the piston is equipped with piston channel.
Further, sealing ring is equipped between the gland and cylinder cap.
Further, dashpot is equipped between the cylinder barrel and piston.
The utility model has the advantage that
This hydraulic cylinder structure is simple, and buffer unit is arranged in hydraulic cylinder both ends, and cushioning principle is increased when piston is in cylinder cap Resistance is had, to reduce the movement velocity of piston, to avoid piston slap cylinder cap.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of double rod type hydraulic cylinder of the present embodiment.
In figure: piston rod 1, gland 2, cylinder cap 3, sealing ring 4, cylinder barrel 5, piston 6, piston channel 7, dashpot 8, taper pin 9, Attachment screw 10.
Specific embodiment
The utility model is further elaborated below in conjunction with attached drawing and by specific embodiment, it should be pointed out that: for this For the common process personnel of technology field, without departing from the principle of this utility model, to the various of the utility model The modification of equivalent form falls within the application range as defined in the appended claims.
Embodiment 1:
As shown in Figure 1, a kind of double rod type hydraulic cylinder, including piston rod 1, gland 2, cylinder cap 3, sealing ring 4, cylinder barrel 5, piston 6, piston channel 7, dashpot 8, taper pin 9, attachment screw 10, are equipped with piston 6 in the cylinder barrel 5, the cylinder barrel 5 and piston 6 it Between be equipped with dashpot 8, the piston 6 connect with taper pin 9, and the piston 6 is equipped with piston channel 7, and the piston rod 1 is across cylinder barrel Interior 5 piston 6, the 5 front and back section of cylinder barrel are connect with cylinder cap 3, and the cylinder cap 3 connect with gland 2 and fixed by attachment screw 10, Sealing ring 4 is equipped between the gland 2 and cylinder cap 3.
The utility model has the advantage that
This hydraulic cylinder structure is simple, and buffer unit is arranged in hydraulic cylinder both ends, and cushioning principle is increased when piston is in cylinder cap Resistance is had, to reduce the movement velocity of piston, to avoid piston slap cylinder cap.
