Further, one side of the inner surface of the limit groove, which is far away from the sealing ring, is provided with an arc surface.
The contact area between the arc surface and the clamping block is increased, the sealing performance and the static friction force are improved, and the stability is improved.
Further, still include clutch housing, the through-hole has been seted up on the clutch housing.
Further, the inner surface of through-hole is provided with the connecting block, the equal fixedly connected with fixture block in both sides of connecting block.
Furthermore, one side of the clamping block is arranged to be an arc-shaped surface matched with the limiting groove.
Further, when the connecting block and the fixture block are correspondingly located in the connecting groove and the limiting groove, the connecting block and the fixture block are in interference fit with the connecting groove and the limiting groove respectively.
Through connecting block cooperation spread groove, fixture block cooperation spacing groove can make axial direction and the straight line direction between sealing washer and the clutch housing all carry on spacingly, when axle rotates relative sealing washer promptly, relative static between sealing washer and the clutch housing, very big reduction is because rotation or linear motion cause wearing and tearing to the surface of O shape circle, improves the life-span of the use of sealing washer, and the sealing washer installation is dismantled simply, is convenient for change
Compared with the prior art, the beneficial effects of the utility model are that:
this O shape circle in clutch piston through connecting block cooperation spread groove, fixture block cooperation spacing groove, can make axial direction and the straight line direction between sealing washer and the clutch housing all carry on spacingly, when the relative sealing washer of axle rotates promptly, relative static between sealing washer and the clutch housing, very big reduction is because rotation or linear motion cause wearing and tearing to the surface of O shape circle, improves the life-span of the use of sealing washer, and the sealing washer installation is dismantled simply, is convenient for change.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an O shape circle in clutch piston, includes sealing washer 1, its characterized in that: the surface of sealing washer 1 is provided with external connection circle 2, spread groove 3 has been seted up on the external connection circle 2, spacing groove 4 has all been seted up to the both sides of 3 internal surfaces of spread groove.
The sealing ring 1 and the external connecting ring 2 are both made of HNBR (hydrogenated nitrile butadiene rubber), have better abrasion resistance, excellent corrosion resistance, tensile resistance, tearing resistance and compression distortion resistance, have excellent resistance under ozone, sunlight and other atmospheric conditions, have the use temperature of-25-150 ℃, have excellent sealing performance no matter for fixation or movement, have smaller required installation space, can be used under high pressure conditions, have simple structure, are easy to install and disassemble, and are easy to obtain and cheap.
One side of the inner surface of the limit groove 4, which is far away from the sealing ring 1, is provided with an arc surface.
The radian of arcwall face is the same with sealing washer 1, and eight are no less than to spread groove 3, and the even surface of array external connection circle 2.
The clutch is characterized by further comprising a clutch shell 5, wherein the clutch shell 5 is provided with a through hole 6.
The inner surface of the through hole 6 is provided with a connecting block 7, and two sides of the connecting block 7 are fixedly connected with clamping blocks 8.
The number and the positions of the connecting blocks 7 correspond to those of the limiting grooves 4.
One side of the clamping block 8 is arranged to be an arc-shaped surface matched with the limiting groove 4.
When the connecting block 7 and the clamping block 8 are correspondingly positioned in the connecting groove 3 and the limiting groove 4, the connecting block 7 and the clamping block 8 are in interference fit with the connecting groove 3 and the limiting groove 4 respectively.
The cooperation of crossing hard makes fixture block 8, connecting block 7 hug closely more with the inner wall of spread groove 3 and spacing groove, guarantees the leakproofness.
According to the working principle, when the sealing ring 1 and the clutch shell 5 are installed, the connecting groove 3 on the external connecting ring 2 on the sealing ring 1 is inserted into the connecting block 7 corresponding to the inner surface of the clutch shell 5, and meanwhile, the fixture blocks 8 on two sides of the connecting block 7 correspondingly extrude the external connecting ring 2, so that the fixture blocks 8 correspond to the position of the limiting groove 4 and enter the limiting groove 4;
the limiting groove 4 and the clamping block 8 and the connecting block 7 and the connecting groove 3 are in interference fit, and the clamping block 8 and the connecting block 7 are tightly attached to the inner walls of the limiting groove 4 and the connecting groove 3, so that the sealing property is ensured;
when the clamping block 8 is taken down, the clamping block 8 is moved out of the limiting groove 4 and then taken down.
Through connecting block 7 cooperation spread groove 3, fixture block 8 cooperation spacing groove 4, can make axial direction and the straight line direction between sealing washer and the clutch housing 5 all carry on spacingly, when axle rotates relative sealing washer 1 promptly, relative static between sealing washer 1 and the clutch housing 5, very big reduction is because rotation or linear motion cause wearing and tearing to the surface of O shape circle, improve the life-span of using.
