Description

A kind of durable piston rod
Technical field
The utility model relates to a kind of durable piston rods.
Background technique
Hydraulic cylinder is one of hydraulic system executive component, and function is exactly the machine that hydraulic energy is transformed into linear reciprocation Tool movement, truck are needed to provide pressure by lifting oil pump for cab in driver's cab turnover and be driven by being driven by hydraulic cylinder Room, this just has higher requirement to the quality of hydraulic cylinder, and the quality of the piston rod as hydraulic cylinder important component is especially Important, existing piston rod packing effect is poor, and piston rod operation has some setbacks in use process.
Utility model content
The purpose of this utility model is that the existing piston rod packing effect of solution is poor, and piston rod operation has some setbacks in use process Smooth problem.
The technical solution adopted in the utility model is: a kind of durable piston rod, including piston bar body, head and piston, Piston is connected to side of the piston bar body far from head, and the piston bar body is fixedly connected with dustband at head, Piston bar body is fixedly connected with guide sleeve at dustband, solid in the piston bar body between guide sleeve and dustband Surely it is connected with retaining ring, the guide sleeve is provided with one of the first inclined-plane, guide sleeve far from dustband close to guide sleeve centerline End is provided with the second inclined-plane, the first sealing ring is provided on the outside of the guide sleeve at the first inclined-plane, at the second inclined-plane It is provided with the second sealing ring on the outside of guide sleeve and is set at the second inclined-plane on the inside of the guide sleeve of piston rod outer body cooperation It is equipped with third sealing ring, the 4th sealing ring is provided on the outside of the piston, is equipped with the through-hole with step, institute on the inside of the piston It states and is provided with the 5th sealing ring in through-hole, be provided on the step of the through-hole and piston bar body is detachable is fixedly connected Snap ring, the side of the snap ring are provided with gland, the 6th sealing ring are provided between the snap ring and the step of through-hole.
The beneficial effects of the utility model are: using the hydraulic cylinder sealing performance of this piston rod after using this structure Good, piston rod is able to bear certain lateral force, and it is close to ensure that piston connect end face reliable and easy for installation with piston bar body Envelope is reliable, and guide sleeve seamlessly transits and have between piston rod preferable sealing, without card resistance in piston rod operational process, ensure that Piston rod is capable of expansion and contraction when flexible, extends piston rod service life.
Detailed description of the invention
Fig. 1 is utility model diagram.
Fig. 2 is the enlarged drawing of piston.
It is as shown in the figure: 1 piston bar body, 2 heads, 3 pistons, 4 dustbands, 5 guide sleeves, 6 retaining rings, 7 first inclined-planes, 8 Two inclined-planes, 9 first sealing rings, 10 second sealing rings, 11 third sealing rings, 12 the 4th sealing rings, 13 the 5th sealing rings, 14 cards Ring, 15 glands, 16 the 6th sealing rings.
Specific embodiment
With reference to the accompanying drawing, the utility model is described further.
As shown, a kind of durable piston rod, including piston bar body 1, head 2 and piston 3, piston is connected to piston rod Side of the ontology far from head, the piston bar body are fixedly connected with dustband 4 at head, and piston bar body is close to anti- It is fixedly connected with guide sleeve 5 at konisphere, is fixedly connected with retaining ring 6 in the piston bar body between guide sleeve and dustband, The guide sleeve is provided with the first inclined-plane 7, guide sleeve close to guide sleeve centerline and one end of dustband is provided with second Inclined-plane 8 is provided with the first sealing ring 9, on the outside of the guide sleeve at the second inclined-plane on the outside of the guide sleeve at the first inclined-plane It is provided with the second sealing ring 10 and is provided with third on the inside of the guide sleeve of piston rod outer body cooperation at the second inclined-plane Sealing ring 11, the piston outside are provided with the 4th sealing ring 12, and the through-hole with step is equipped on the inside of the piston, described logical It is provided with the 5th sealing ring 13 in hole, is provided on the step of the through-hole and the detachable card being fixedly connected of piston bar body Ring 14, the side of the snap ring are provided with gland 15, the 6th sealing ring 16 are provided between the snap ring and the step of through-hole.
In the utility model, dustband can play dust-proof effect, and retaining ring is capable of the movement of restricted guidance set, guide sleeve Inclined-plane be convenient for piston rod movement, snap ring and gland guarantee end face seal and piston are made to be easy to dismount, and each sealing ring guarantees close Sealing property.
Those skilled in the art should know the protection scheme of the utility model is not limited only to the above embodiments, may be used also To carry out various permutation and combination and transformation on the basis of the above embodiments, without departing from the spirit of the present invention, The various transformation carried out to the utility model are all fallen in the protection scope of the utility model.
