Description

Technical Field

[0001] The utility model relates to the technical field of fluid transportation, in particular to a tire self-sealing glue rotating and sealing pipeline mechanism. Background Art

[0002] Repairing a tire mainly involves applying a layer of rubber-based viscous sealant on the inside of the tire. The sealant has a strong viscosity. When a nail pierces the tire, the sealant will wrap around the nail to prevent gas from leaking from the gap. When we pull out the nail, the sealant has fluidity and can quickly enter the punctured hole, achieving the purpose of self-repair of the tire.

[0003] Among them, the fluid conveying pipelines commonly used by self-sealing adhesives are connected by flanges, which is not convenient for movable connection between the pipelines. In addition, the rotatable pipelines have matching gaps. The sealant is a fluid and there is a risk of leakage. Therefore, a special sealing structure is required for the pipeline mechanism to ensure that the conveyed fluid will not leak. Utility Model Content

[0006] The effect achieved by the above components is: the outer ring A and the outer ring B can cooperate with the steel balls to form a mutual rotational fit between the upstream pipeline connected to the inner ring A and the downstream pipeline connected to the inner ring B, wherein the cooperation of the six groups of steel balls and the circular ring track can ensure the strength and rigidity of the rotation, and can also ensure the concentricity of the rotation without deformation. In addition, the high-temperature resistant sealing ring assembly arranged between the inner ring A and the inner ring B that rotate with each other can perform dynamic sealing to avoid leakage when conveying tire self-sealant.

[0007] Preferably, the outer walls of the A outer ring and the B outer ring are both provided with side holes connected to the circular track, and steel ball top screws for adjusting the pre-pressure of the steel ball are fixed in the side holes.

[0008] The effect achieved by the above components is: by adjusting the pre-pressure of the steel ball top screw, the steel balls are pressed against each other and roll flexibly in the circular track to achieve the rotation function.

[0009] Preferably, the high temperature resistant sealing ring assembly includes an annular sealing groove opened on the inner side wall of the A inner ring, and the sealing groove is provided with an O-ring and a lip-shaped rectangular ring superimposed on each other, and the inner side of the lip-shaped rectangular ring is in contact with the outer wall of the B inner ring extension portion.

[0010] The effect achieved by the above components is: the shape of the lip-shaped rectangular ring in contact with the outer wall of the inner ring B is different. After the tire self-sealant fluid enters the contact surface on the inner ring B, as the tire self-sealant fluid pressure increases, the sealing lip will tightly hold the outer axial surface of the inner ring B to form a sealing function, wherein the O-ring is a force-applying element, providing sufficient sealing force and compensating for the lip-shaped rectangular ring.

[0011] Preferably, the O-ring is made of fluororubber material, and the lip-shaped rectangular ring is made of polytetrafluoroethylene material.

[0012] The effects achieved by the above components are: the O-ring made of fluororubber material and the lip-shaped rectangular ring made of polytetrafluoroethylene can ensure that they will not age or deform in an environment below 200 degrees.

[0013] Preferably, the diameter of the circular track is 6 mm, and the diameter of the steel ball is 5.8 mm.

[0014] Preferably, the A inner ring, the A outer ring, the B inner ring and the B outer ring are all made of the same alloy steel material and are provided with a hard chrome plating layer with a thickness of 0.05 mm after surface quenching and fine grinding.

[0015] The effects achieved by the above components are: using the same alloy steel material to minimize the difference in gap size under different temperatures, and the steel balls rolling in the circular track with hard chrome plating will not deform, thus ensuring the rotation accuracy and service life.

[0016] The utility model provides a tire self-sealing glue rotating and sealing pipeline mechanism through improvement, which has the following improvements and advantages compared with the prior art:

[0017] First, the utility model can cooperate with the steel balls through the outer ring A and the outer ring B to form a mutual rotational cooperation between the upstream pipeline connected to the inner ring A and the downstream pipeline connected to the inner ring B, wherein the cooperation of the six groups of steel balls and the circular track can ensure the strength and rigidity of the rotation, and can also ensure the concentric rotation without deformation;

[0018] Secondly, the shape of the lip-shaped rectangular ring in contact with the outer wall of the inner ring B is different. After the tire self-sealant fluid enters the contact surface on the inner ring B, as the tire self-sealant fluid pressure increases, the sealing lip will tightly hug the outer axial surface of the inner ring B to form a sealing function, wherein the O-ring is a force-applying element, providing sufficient sealing force and compensating for the lip-shaped rectangular ring.

By adjusting the pre-pressure of the steel ball top screws 10, the steel balls 11 can be pressed against each other and roll flexibly in the circular tracks. The A inner ring 3, the A outer ring 4, the B inner ring 7 and the B outer ring 6 are all made of the same alloy steel material and are provided with a hard chrome plating with a thickness of 0.05mm after surface quenching and fine grinding.

[0030] In an embodiment of the utility model, a high temperature resistant sealing ring assembly includes an annular sealing groove 12 provided on the inner side wall of the A inner ring 3, and an O-ring 13 and a lip-shaped rectangular ring 14 are arranged in the sealing groove 12.
