Description

Technical Field

[0001] This utility model belongs to the field of hydraulic brakes, and in particular relates to a rotary oil pipe joint for connecting brake oil pipes. Background Technology

[0002] Current bicycle hydraulic brakes connect a hydraulic hose between the master cylinder and the hydraulic caliper. The hose guides hydraulic fluid from the master cylinder to the caliper, causing it to clamp against the wheel disc and apply braking. However, bicycle brakes typically have the brake lever located on the handlebars, while the hydraulic caliper is positioned next to the wheel disc. But bicycle handlebars need to be changed depending on road conditions, and changing handlebars requires repeatedly disassembling and reassembling the hydraulic hose, making the installation process cumbersome. Therefore, designing a hydraulic hose connector that allows for quick and easy assembly and disassembly is one of the most important research topics. Utility Model Content

[0064] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0065] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0066] The following is a reference to the appendix. Figure 1 To be continued Figure 9 The rotary oil pipe joint system of this utility model includes:

[0067] The first connector assembly 1 has a first connector 2 and a first drive assembly 3. One end of the first connector 2 has a positioning protrusion 210, and the first drive assembly 3 is housed inside the first connector 2 and has an abutment portion 303 corresponding to one end of the positioning protrusion 210.

[0068] The second connector assembly 4 has a second connector 40, a second drive assembly 41, and a positioning ring 42. The second drive assembly 41 has a first engagement section 432 and a second engagement section 433 at its two ends. The first engagement section 432 engages with the second connector 40. The second engagement section 433 protrudes out of the outer side of the second connector 40 and has an abutment groove 434 corresponding to the abutment portion 303. The positioning ring 42 has a through hole 420 on one side and rotates to engage with the second engagement section 433. The circumferential surface of the positioning ring 42 is provided with a continuous longitudinal groove 421 and a transverse groove 422. One end of the longitudinal groove 421 is connected to the through hole 420 and the other end is connected to the transverse groove 422. The other end of the transverse groove 422 has a positioning groove 423 corresponding to the positioning protrusion 210.

[0069] In this process, the abutting groove 434 of the second drive component 41 and the abutting part 303 of the first drive component 3 push against each other, forcing the positioning protrusion 210 of the first pipe 2 to pass through the through hole 420 into the longitudinal groove 421 of the positioning ring 42. Then, the positioning ring 42 is rotated so that the positioning protrusion 210 of the first pipe 2 slides into the positioning groove 423 along the transverse groove 422 to form a positioning, thus completing the engagement action of the first connector component 1 and the second connector component 4.

[0070] The foregoing are the main technical features of the main embodiment of this invention, which correspond to the content of claim 1 of the patent application in this case, so that the purpose and implementation mode of this invention can be understood in detail. The technical features described in the other appended claims are detailed descriptions or additional technical features of claim 1 of the patent application, and are not used to limit the scope of claim 1 of the patent application. It should be understood that claim 1 of the patent application of this invention does not necessarily include the technical features described in the other appended claims.

[0071] The following further explains the composition, operation, and function of each of the above components:

[0072] First, the new rotary oil pipe joint is connected between the first oil pipe 5 and the second oil pipe 6 of the bicycle's oil pipe assembly.

[0073] The first connector 2 has a first joint 20 and a second joint 21 at both ends. The first joint 20 has a first connection hole 200 and is connected to the outside of the first oil pipe 5 through the first connection hole 200. The second joint 21 has a positioning protrusion 210.

[0074] Furthermore, the first drive assembly 3 has a first valve 30, a first retaining ring 31, and a first spring 32. The first valve 30 is housed inside the first connecting pipe 2 and has a first convex wall 300 in the middle position, while the two ends are respectively provided with a first valve stem 301 and a second valve stem 302. The first valve stem 301 is connected to and communicates with the first oil pipe 5. The second valve stem 302 is inserted into the first connecting pipe 2 through the first connecting hole 200 and forms an abutment part 303 at one end of the corresponding positioning protrusion 210. Then, the first spring 32 is first sleeved on the second valve stem 302, and then the first retaining ring 31 is sleeved on the end of the second valve stem 302, so that the two ends of the first spring 32 abut between the first retaining ring 31 and the first convex wall 300 respectively. In this embodiment, the first retaining ring 31 pushes against the first spring 32, causing the first spring 32 to elastically contract. The first oil pipe 5 has a first oil passage 50 inside, and the first valve member 30 has a first valve passage 304 communicating with the first oil passage 50 inside. The first retaining ring 31 is provided with a bearing 310 that contacts the second valve stem 302. The bearing 310 prevents the first retaining ring 31 from directly contacting the second valve stem 302, thus avoiding damage to the first retaining ring 31 when it is displaced.

[0075] Furthermore, the second connector 40 has a third joint 400 and a fourth joint 401 at its two ends, respectively. The third joint 400 is engaged with the outside of the second oil pipe 6, and one end of the fourth joint 401 has a second connection hole 402.

[0076] Furthermore, the second drive assembly 41 includes a second valve member 43, a second retaining ring 44, and a second spring 45. The outer circumference of the second valve member 43 is provided with a second protruding wall 430 and a retaining ring portion 431 spaced apart. The two ends of the second valve member 43 are respectively provided with a first connecting section 432 and a second connecting section 433. The first connecting section 432 is provided with the second protruding wall 430 and is connected to the second oil pipe 6 via a second connecting hole 402. The second connecting section 433 is provided with a retaining ring portion 431. The second spring 45 is first placed inside the second connecting section 433, and then the second retaining ring 44 is placed in the abutment groove 434 of the second connecting section 433, so that the two ends of the second spring 45 abut against the second retaining ring 44 and the second protruding wall 430 respectively. In this example, the second oil pipe 6 has a second oil passage 60 inside, and the second valve member 43 has a second valve passage 435 communicating with the second oil passage 60. Furthermore, the circumferential surface of the positioning ring 42 also has a retaining groove 424 that is movably engaged with the retaining ring portion 431 of the second engagement section 433, thereby allowing the positioning ring 42 to rotate relative to the second engagement section 433.

[0077] In use, the first connector assembly 1 and the second connector assembly 4 are correspondingly arranged. The first connecting pipe 2 is connected to the second connecting section 433 of the second valve member 43, so that the abutting part 303 of the second valve stem 302 abuts against the abutting groove 434 of the second connecting section 433, so that the first retaining ring 31 and the second retaining ring 44 push against each other, forcing the first spring 32 and the second spring 45 to elastically contract respectively. At the same time, the positioning protrusion 210 of the first connecting pipe 2 can pass through the through hole 420 of the positioning ring 42 into the longitudinal groove 421. Then, the positioning ring 42 is rotated so that the positioning protrusion 210 of the first connecting pipe 2 slides into the positioning groove 423 along the transverse groove 422, so that the first connecting pipe 2 and the positioning ring 42 form a positioning relationship (as shown in Figures 5 and 6), thereby completing the connection operation of the first connector assembly 1 of the first oil pipe 5 and the second connector assembly 4 of the second oil pipe 6.

[0078] Conversely, when disassembling the first oil pipe 5 and the second oil pipe 6, the positioning ring 42 is rotated in the opposite direction, causing the positioning protrusion 210 of the first connecting pipe 2 to exit the positioning groove 423 and move to the connection position between the transverse groove 422 and the longitudinal groove 421, thereby releasing the positioning relationship between the positioning protrusion 210 and the positioning groove 423. At this time, the first connecting pipe 2 can be separated from the second connecting section 433, releasing the abutting relationship between the abutting part 303 of the second valve stem 302 and the abutting groove 434 of the second connecting section 433. At the same time, the first spring 32 and the second spring 45 are in an elastically released state, causing the first retaining ring 31 and the second retaining ring 44 to return to their original positions outwards, thereby completing the separation operation of the first connector assembly 1 of the first oil pipe 5 and the second connector assembly 4 of the second oil pipe 6. In other words, this invention allows for the rapid assembly and disassembly of the first connector assembly 1 and the second connector assembly 4 of the second oil pipe 6 by rotating the positioning ring 42.
