[0031] like Figures 1 to 4 As shown, the utility model provides a cylinder sealing ring positioning device, including a first pressing block 100 and a second pressing block 200. Among them, the bottom of the first clamping block 100 is provided with a first connecting end 110, and the first connecting end 110 is detachably connected to the cylinder body 10, and the top of the first clamping block 100 is provided with a first arc-shaped clamping end 120, and the first arc-shaped clamping end 120 is provided with a first arc-shaped opening 121; the bottom of the second clamping block 200 is provided with a second connecting end 210, and the second connecting end 210 is detachably connected to the cylinder body 10, and a part of the second connecting end 210 presses the first connecting end 110, thereby improving the stability of the first connecting end 110, and the top of the second clamping block 200 is provided with a second arc-shaped clamping end 220, the second arc-shaped clamping end 220 cooperates with the first arc-shaped clamping end 120 to compress the piston rod sealing ring 20, and the second arc-shaped clamping end 220 is provided with a second arc-shaped opening 221, and the second arc-shaped opening 221 and the first arc-shaped opening 121 form a circular opening, and the cylinder piston rod 30 passes through the circular opening.

[0032] The cylinder seal ring positioning device provided by the present invention is provided with a first pressing block 100 and a second pressing block 200. When the piston rod seal ring 20 is dislodged, the first pressing block 100 is detachably connected to the cylinder body 10 via the first connecting end 110, and the second pressing block 200 is detachably connected to the cylinder body 10 via the second connecting end 210. The first arcuate pressing end 120 of the first pressing block 100 and the second arcuate pressing end 220 of the second pressing block 200 are used in conjunction to compress and position the piston rod seal ring 20. The dislodged piston rod seal ring 20 can be re-compressed without disassembling the components at the cylinder connection, thereby improving maintenance efficiency, saving maintenance time, and ensuring production continuity. The cylinder seal ring positioning device can also be installed simultaneously with the installation of the cylinder, which can prevent the piston rod seal ring 20 from being dislodged, reduce cylinder leakage and transmission instability.

[0033] In some embodiments, the first connection end 110 is provided with a first through hole 111, and the second connection end 210 is provided with a connecting portion 211. The connecting portion 211 presses the first connection end 110, and the connecting portion 211 is provided with a second through hole 212 aligned with the first through hole 111. The screw 213 passes through the second through hole 212 and the first through hole 111 and is threadedly connected to the cylinder body 10. With the above structure, when the cylinder sealing ring positioning device is installed on the cylinder, the first connection end 110 is first placed on the cylinder body 10, and then the second connection end 210 is placed on the cylinder body 10. At this time, the connecting portion 211 presses the first connection end 110, and then the screw 213 is sequentially passed through the second through hole 212 and the first through hole 111 and threadedly connected to the cylinder to ensure the stability of the first connection end 110 and the second connection end 210.

[0034] Optionally, the second connection end 210 is provided with an escape groove 214, which is located on a side of the connection portion 211 near the first connection end 110. The escape groove 214 can accommodate the area where the connection portion 211 presses against the first connection end 110. The depth of the escape groove 214 is no less than the thickness of the first connection end 110, allowing both the first connection end 110 and the second connection end 210 to fit snugly against the cylinder block 10.

[0035] In some specific embodiments, there are at least two first through holes 111 to ensure stability between the first connection end 110 and the second connection end 210. The first connection end 110 defines a first connection hole 112, through which a first bolt 113 passes and is threadedly connected to the cylinder body 10, thereby improving the secure connection between the first connection end 110 and the cylinder body 10. The second connection end 210 defines a second connection hole 215, through which a second bolt 216 passes and is threadedly connected to the cylinder body 10, thereby improving the secure connection between the second connection end 210 and the cylinder body 10. The first and second compression blocks 100, 200 can be made of, but are not limited to, aluminum alloy, stainless steel, or copper alloy.
