Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe joints, in particular to a motorcycle brake oil pipe joint. Background Art

[0002] In motorcycle braking systems, the brake oil pipe joint is a key component connecting the brake hose and the oil pipe. Its connection reliability and assembly convenience directly affect the safety and production efficiency of the braking system.

[0003] Prior art motorcycle brake fluid pipe connectors often utilize either a one-piece fixed connection or a complex, nested, multi-component connection. During assembly, due to the rigid nature of the connector's connection to the pipe or hose, a rotational force often needs to be applied to the entire pipe or connector to secure it. This can easily transfer external force to the pipe itself, causing it to twist, bend, or even damage its internal structure, impacting the proper flow of brake fluid and posing a safety hazard. Furthermore, traditional connectors require cumbersome installation procedures and complex assembly and disassembly processes.

[0004] Therefore, how to design a brake oil pipe joint that can avoid damage to the oil pipe caused by external force during installation, simplify the assembly process and ensure connection reliability has become a technical problem that needs to be solved urgently in this field. Utility Model Content

[0005] In view of the deficiencies in the background technology, the utility model provides a motorcycle brake oil pipe joint.

[0006] The technical solution adopted by the utility model is: a motorcycle brake oil pipe joint, comprising:

[0007] A pipe connection portion, the pipe connection portion including a hose connection portion and an oil pipe connection portion, wherein an outer wall of one end of the oil pipe connection portion is provided with an external thread and a steel ball hole, a docking hole is provided in the oil pipe connection portion, and a fixed steel ball is movably installed in the steel ball hole;

[0008] An oil pipe joint, one end of which is provided with a docking section, which is inserted into the docking hole and is rotatably sealed therewith, and an outer wall of the docking hole is provided with a fixed ring groove corresponding to the fixed steel ball;

[0009] A fixed screw sleeve is provided with an internal thread that cooperates with the above-mentioned external thread on the inner wall of one end of the fixed screw sleeve, and a pressure step is provided on the inner hole wall of the fixed screw sleeve for pressing the fixed steel ball into the docking hole and connecting with the fixed ring groove.

[0010] Furthermore, a raised sealing step is provided in the docking hole, and the sealing step transitions to the inner wall of the docking hole through an inclined surface. At least one circle of sealing groove is provided on the outer wall of the docking section, and a sealing ring is installed in the sealing groove.

[0011] Furthermore, a limiting step ring is provided on a side of the docking section away from the docking hole.

[0012] Furthermore, the pressure step and the inner hole wall of the fixing screw sleeve are transitioned through an inclined surface or a rounded corner.

[0013] Furthermore, a friction-increasing groove is provided on the outer wall of the fixing screw sleeve. The friction-increasing groove is a strip-shaped structure extending from one end of the fixing screw sleeve to the middle of the fixing screw sleeve.

[0014] Furthermore, a plurality of friction-increasing convex strips are provided on the outer wall of the hose connecting portion, and the friction-increasing convex strips are arranged at intervals along the length direction of the hose connecting portion.

[0015] The beneficial effects of the utility model are:

[0016] First, by adopting a rotary connection method in which only the mating section of the oil pipe joint rotates, external force can be prevented from being transmitted to the oil pipe during installation. This fundamentally solves the problem of oil pipe twisting, bending, and even internal structure damage caused by overall rotation in traditional connection methods, ensures the normal circulation of brake fluid, and improves the safety of the braking system.

[0017] Second, when assembling this application, you only need to insert the docking section into the docking hole and then tighten the fixing screw sleeve in two simple steps to complete the assembly, which greatly simplifies the installation steps and improves production efficiency. In addition, the disassembly and assembly process is more convenient during later maintenance or replacement.

[0018] In addition to the objects, features and advantages described above, the present invention has other objects, features and advantages.

[0026] The utility model provides a brake oil pipe joint for a motorcycle.

[0027] In this embodiment, referring to Figure 1-3 The motorcycle brake oil pipe joint includes:

[0028] The pipe connection part includes a hose connection part 1 and an oil pipe connection part 2. An external thread 3 and a steel ball hole 4 are provided on the outer wall of one end of the oil pipe connection part 2. A docking hole 5 is provided in the oil pipe connection part. A fixed steel ball 6 is movably installed in the steel ball hole 4.

[0029] An oil pipe joint 7, one end of which is provided with a docking section 8, which is inserted into the docking hole and rotatably sealed therewith, and an outer wall of the docking hole is provided with a fixed ring groove 9 corresponding to the fixed steel ball;

[0030] The fixing screw sleeve 10 has an inner thread 11 on the inner wall of one end thereof which matches the outer thread, and a pressure step 12 for pressing the fixing steel ball into the docking hole and connecting with the fixing ring groove is provided on the inner hole wall of the fixing screw sleeve.

[0031] In this technical solution, the butt hole of the oil pipe connector is inserted into the butt section of the oil pipe joint, and the two are connected by rotation and sealing. The fixing screw sleeve's internal threads mate with the external threads of the oil pipe connector. The pressure step on its inner wall presses the fixing steel ball toward the butt hole, where it engages with the fixing ring groove on the outer wall of the butt section, thus securing the oil pipe joint to the pipe connector.

[0032] This allows for a rotating connection between the tubing connector and the connecting section, preventing external forces from being transferred to the tubing during installation and protecting the integrity of the tubing. Assembly is accomplished in two simple steps: inserting the connecting section into the docking hole and tightening the securing screw. This significantly improves assembly efficiency, facilitates assembly and disassembly, and ensures a secure connection.

[0033] Specifically, a raised sealing step 13 is provided in the docking hole, and the sealing step 13 transitions to the inner wall of the docking hole through an inclined surface 14. At least one circle of sealing grooves 15 is provided on the outer wall of the docking section, and a sealing ring 16 is installed in the sealing groove.

[0034] In this embodiment, a sealing step within the docking hole mates with a sealing ring within a sealing groove on the outer wall of the docking section. The beveled transition between the sealing step and the inner wall of the docking hole facilitates smoother insertion of the docking section, while the sealing ring fills the gap between the sealing step and the docking section. This enhances the seal between the docking section and the docking hole, effectively preventing brake fluid leakage.

[0035] Specifically, a limiting step ring 17 is provided on the side of the docking section away from the docking hole.

[0036] In this embodiment, the limiting step ring on the side of the docking section away from the docking hole can play a limiting role when the docking section is inserted into the docking hole, thereby preventing the docking section from being over-inserted into the docking hole.

[0037] Specifically, the pressure step and the inner hole wall of the fixing screw sleeve are transitioned through an inclined surface or a rounded corner.

[0038] In this embodiment, the pressure step and the inner wall of the fixing screw sleeve are transitioned through an inclined surface or a rounded corner, so that the pressure of the pressure step on the fixing steel ball can be transmitted more smoothly during the tightening process of the fixing screw sleeve.

[0039] Specifically, a friction-increasing groove 18 is provided on the outer wall of the fixing screw sleeve. The friction-increasing groove is a strip-shaped structure extending from one end of the fixing screw sleeve to the middle of the fixing screw sleeve.

[0040] In this embodiment, the strip-shaped friction-increasing groove on the outer wall of the fixing screw sleeve increases the friction between the hand or tool and the fixing screw sleeve, and the groove extends from one end to the middle, making it easier to apply force and facilitate manual rotation of the fixing screw sleeve.

[0041] Specifically, a plurality of friction-increasing ridges 19 are provided on the outer wall of the hose connecting portion, and the friction-increasing ridges are arranged at intervals along the length direction of the hose connecting portion.

[0042] In this embodiment, a plurality of friction-increasing ridges on the outer wall of the pipe connecting portion are arranged at intervals along the length direction to increase surface friction.

[0043] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
