Description

Technical Field

[0001] This utility model relates to a ball joint in the field of automotive parts, specifically a ball joint with a built-in sealing ring. Background Technology

[0002] A ball joint is a type of connector used to connect brake lines. Existing ball joints have one annular end, locked to the valve body by a hollow bolt, with the upper and lower ends sealed by annular copper gaskets. The other end is a tapered connector with a rubber tube installed externally, its end secured by a sleeve. Because the ball joint, hollow bolt, and valve body are all made of iron, and the annular copper gaskets are made of copper, when oil flows through the ball joint, the oil temperature rises in tandem with the equipment temperature, and the ball joint also heats up. When the equipment stops, the hydraulic oil and the ball joint slowly return to room temperature. During this constant thermal expansion and contraction, due to the different materials of the copper gaskets and the ball joint, their expansion coefficients differ, eventually causing the bolt to loosen, leading to slow oil leakage from the upper and lower parts of the ball joint. Therefore, a ball joint with a reduced leakage probability is needed to replace the existing one.

[0003] Application No.: ZL2024211625388 A quick-release hydraulic hose connector assembly for a brake fluid circuit includes a rigid hydraulic hose connector with a hose inlet section having a connector hydraulic passage; a flexible hydraulic hose assembly with a hose hydraulic passage communicating with the connector hydraulic passage; a quick-release locking sleeve with a socket hole through which the flexible hydraulic hose assembly passes; one of the hose inlet section and the quick-release locking sleeve has a groove to form a variable-diameter elastic clamp section; the other has a compression part that abuts against the elastic clamp section, causing the elastic clamp section to contract, and the contracted elastic clamp section clamps the flexible hydraulic hose assembly. This utility model can automatically assemble and disassemble the rigid hydraulic hose connector and the flexible hydraulic hose assembly without the need for special equipment. The assembly and disassembly operations are simple, convenient, and quick, greatly shortening the operation time and achieving a quick-release and quick-installation effect.

[0004] The aforementioned quick-release oil pipe joint assembly in a brake hydraulic circuit employs an oil pipe joint, an oil pipe access section, a joint oil circuit channel, an oil pipe oil circuit channel, a quick-release locking sleeve, a socket, a groove, a variable-diameter elastic clamp section, and a compression part to achieve the assembly and disassembly of the rigid oil pipe joint and the flexible oil pipe assembly. Utility Model Content

[0005] This utility model discloses a spherical connector with a spherical connecting body. The connecting body has contact surfaces at the top and bottom, a sealing ring on the top of the contact surfaces, a cavity inside the connecting body, and a conical conduit on the side of the connecting body. The sealing ring, hollow bolt, and valve body are made of the same material and have the same coefficient of expansion, effectively ensuring the sealing performance.

[0006] The technical solution of this utility model is as follows: a spherical connector includes a connecting body 1, an inner sealing ring 5 and an outer sealing ring 6 are provided on the upper part of the connecting body 1, an inner sealing ring 5 and an outer sealing ring 6 are provided on the lower part of the connecting body 1, an upper ring opening 2, a cavity 3 and a lower ring opening 4 are provided inside the connecting body 1, a conduit 8 is provided on the side of the connecting body 1, and a tapered buckle 7 is provided on the upper part of the conduit 8.

[0007] Furthermore, the connecting body 1 is an iron ring, the central cavity 3 inside is a ring groove, the inner ring above the cavity 3 is an upper ring opening 2, and the inner ring below the cavity 3 is a lower ring opening 4.

[0008] Furthermore, the connecting body 1 has an annular plane on its upper surface, and the inner sealing ring 5 above the inner ring of the plane is an annular protrusion with a width of 1-2 mm. The outer sealing ring 6 above the outer ring of the plane of the connecting body 1 is an annular protrusion with a width of 1-2 mm.

[0009] Furthermore, an annular plane is provided on the bottom of the connecting body 1, an inner sealing ring 5 is provided below the inner ring of the plane, and an outer sealing ring 6 is provided below the outer ring of the plane of the connecting body 1.

[0010] Furthermore, the conduit 8 provided on the side of the connector 1 is cylindrical, and the conduit 8 is connected to the cavity 3. Five to eight conical buckles 7 are provided on the upper right end of the conduit 8, and the conical buckles 7 are conical rings that are larger on the left and smaller on the right.

[0011] Beneficial effects: During the ordinary process of thermal expansion and contraction, due to the different materials of the copper gasket and the ball joint, the expansion coefficient will also be different. Over time, the bolt will loosen, causing oil to slowly seep from the upper and lower parts of the ball joint.

[0012] A spherical connector uses a spherical connector with contact surfaces at the top and bottom, a sealing ring on the top of the contact surfaces, a cavity inside the connector, and a conical conduit on the side of the connector. The sealing ring is made of the same material as the hollow bolt and the valve body, has the same coefficient of expansion, and effectively ensures the sealing performance.

[0015] The shape and structure of this utility model will be carefully described in conjunction with the accompanying drawings and reference numerals: Example

[0016] See appendix Figure 1 A spherical connector includes a connecting body 1, which supports an upper ring 2, a cavity 3, a lower ring 4, an inner sealing ring 5, and an outer sealing ring 6. The upper part of the connecting body 1 has the inner sealing ring 5 and the outer sealing ring 6, which are used to seal against a hollow bolt. The lower part of the connecting body 1 also has the inner sealing ring 5 and the outer sealing ring 6, which are used to seal against a valve body. The interior of the connecting body 1 has the upper ring 2, the cavity 3, and the lower ring 4, which are used to position the hollow bolt. The cavity 3 is used to guide oil transported by a conduit 8 into the hollow bolt. The side of the connecting body 1 has a conduit 8, which is used to guide oil into the cavity 3 and to install a steel wire hose externally. The upper part of the conduit 8 has a tapered buckle 7, which is used to hook the steel wire hose to prevent it from falling off.

[0017] See appendix Figure 1 The connecting body 1 is an iron ring, and the cavity 3 in the center of the cavity is a ring groove. The inner ring above the cavity 3 is an upper ring opening 2, and the inner ring below the cavity 3 is a lower ring opening 4.

[0018] See appendix Figure 1 The connecting body 1 has an annular plane on its upper surface. The inner sealing ring 5 above the inner ring of the plane is a circular protrusion with a width of 1-2 mm. The outer sealing ring 6 above the outer ring of the plane of the connecting body 1 is a circular protrusion with a width of 1-2 mm.

[0019] See appendix Figure 1 The connecting body 1 has an annular plane on its lower surface, an inner sealing ring 5 on its inner ring, and an outer sealing ring 6 on its outer ring.

[0020] See appendix Figure 1 The conduit 8 provided on the side of the connector 1 is cylindrical and is connected to the cavity 3. Five to eight conical buckles 7 are provided on the upper right end of the conduit 8. The conical buckles 7 are conical rings that are larger on the left and smaller on the right.

[0021] Based on the above simple description of the usage process of a ball joint, the worker inserts a metal sleeve onto the top of the conduit 8, then inserts a steel wire hose onto the top of the conduit 8, and finally uses a crimping machine to tighten the metal sleeve (pressure > 8 MPa). The worker inserts a hollow bolt into the upper ring 2, cavity 3, and lower ring 4, with the lower end of the hollow bolt connected to the inlet of the valve body. The worker uses a heavy-duty wrench to tighten the hollow bolt, forcing the inner sealing ring 5 and outer sealing ring 6 above the connector 1 to fit tightly with the nut of the hollow bolt, and forcing the inner sealing ring 5 and outer sealing ring 6 below the connector 1 to fit tightly with the valve body. When the oil enters the cavity 3 through the conduit 8, the oil then enters the interior of the hollow bolt through the bypass hole and flows into the valve body. The inner sealing ring 5 and outer sealing ring 6 are made of the same material as the hollow bolt and the valve body, and have the same coefficient of expansion, effectively ensuring the sealing performance of the ball joint and reducing oil leakage.
