Description
Technical Field
The utility model relates to a pneumatic cylinder field, concretely relates to uide bushing rubber seal for pneumatic cylinder support.
Background
A sealing ring is arranged between the connection of a hydraulic rod and a guide sleeve of the hydraulic cylinder, so that the hydraulic rod and the guide sleeve are kept sealed, and the pushing effect of hydraulic oil is ensured.
Current sealing washer seals hydraulic stem and uide bushing through one V type groove and seal lip, and sealed effect is general, reveals hydraulic oil easily between uide bushing and the hydraulic stem, and the safety of pneumatic cylinder can not be guaranteed, consequently needs a utility model to solve current problem.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to overcome prior art not enough, provide a uide bushing rubber seal that prevents dust for pneumatic cylinder support now, solved current sealing washer and sealed hydraulic stem and uide bushing through one V type groove and seal lip, sealed effect is general, reveals hydraulic oil easily between uide bushing and the hydraulic stem, and the safety of pneumatic cylinder can not obtain the problem of guaranteeing.
(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a uide bushing rubber seal that prevents dust for pneumatic cylinder support, including circle body, V type groove and seal lip, circle body downside shaping has V type groove, V type groove one side shaping has the seal lip, circle internal side is provided with sealed inner ring, the inboard shaping of sealed inner ring has U type groove.
Furthermore, a ring groove is formed on the inner side of the upper end of the ring body, and the ring body is glued with the sealing inner ring.
By adopting the technical scheme, leaked hydraulic oil can be stored in the ring groove, so that the ring body on one side of the ring groove is tightly attached to the hydraulic rod under the action of the pressure of the hydraulic oil, and the sealing performance is ensured.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
for solving current sealing washer and sealing up through one V type groove and seal lip to hydraulic stem and uide bushing, sealed effect is general, reveals hydraulic oil easily between uide bushing and the hydraulic stem, the problem that the safety of pneumatic cylinder can not be guaranteed, the utility model discloses a sealed inner ring, U type groove and the ring groove that set up for the sealing washer passes through V type groove, U type groove, ring groove, sealed inner ring and seal lip and seals up hydraulic stem and uide bushing, improves sealed effect greatly, avoids revealing hydraulic oil between uide bushing and the hydraulic stem, guarantees the safe in utilization of pneumatic cylinder.

Fig. 1 is the utility model discloses a uide bushing rubber seal's for pneumatic cylinder support main cross-sectional view.
The reference numerals are explained below:
1. a loop body; 2. a V-shaped groove; 3. a sealing lip; 4. sealing the inner ring; 5. a U-shaped groove; 6. a ring groove.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, this embodiment of a guide sleeve rubber seal ring for hydraulic cylinder support, including circle body 1, V type groove 2 and seal lip 3, the shaping of 1 downside of circle body has V type groove 2, the shaping of 2 one side in V type groove has seal lip 3, circle body 1 inboard is provided with sealed inner ring 4, the shaping of 4 inboard sides in sealed inner ring has U type groove 5, the shaping of 1 upper end inboard in circle body has annular groove 6, circle body 1 splices with sealed inner ring 4.
As shown in fig. 1, in this embodiment, the shaping of 1 downside of circle body has V type groove 2, the shaping of 2 one side in V type groove has sealing lip 3, 1 inboard of circle body is provided with sealed inner ring 4, the inboard shaping of 4 inboard in sealed inner rings has U type groove 5, the inboard shaping in 1 upper end of circle body has ring groove 6, sealed inner ring 4 through setting up, U type groove 5 and ring groove 6, make the sealing washer pass through V type groove 2, U type groove 5, ring groove 6, sealed inner ring 4 and sealing lip 3 seal up hydraulic stem and uide bushing, improve sealed effect greatly, avoid revealing hydraulic oil between uide bushing and the hydraulic stem, guarantee the safe in utilization of pneumatic cylinder.
The specific implementation process of this embodiment is as follows: when using, overlap ring body 1 between hydraulic stem and uide bushing, receive the pressure of hydraulic oil in V type groove 2, make seal lip 3 can hug closely on the hydraulic stem, and then make the leakproofness between hydraulic stem and the uide bushing improve greatly, when seal lip 3 reveals hydraulic oil, hydraulic oil can enter into U type groove 5 on the sealed inner ring 4, and then make the sealed inner ring 4 inflation on the U type groove 5, make sealed inner ring 4 can hug closely the hydraulic stem, guarantee the leakproofness between hydraulic stem and the uide bushing, when sealed inner ring 4 department hydraulic oil reveals, hydraulic oil enters into annular groove 6, annular groove 6 expands under the pressure effect of hydraulic oil, and then make ring body 1 upper end inflation, make the leakproofness improve greatly between hydraulic stem and the uide bushing, guarantee the safety in utilization of pneumatic cylinder.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
