Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic brake pipelines, in particular to a quick-detachable oil pipe joint component in a brake oil circuit. Background Art

[0002] In vehicles such as bicycles, the device used to control the brakes is the brake. In pursuit of braking efficiency and accuracy, hydraulic brakes are widely used in vehicles on the market (such as cars, motorcycles and bicycles). The principle is to connect one end of a brake oil pipe to the output end of the internal oil circuit of a brake handle seat, and the other end of the brake oil pipe is connected to a disc brake. The handle can be pressed to push a piston rod in the internal oil circuit, so that the pressure in the oil circuit acts on the disc brake through the brake oil pipe, forming a disc brake operation, also known as hydraulic brake.

[0003] In hydraulic brakes, the oil pipe is soft, one end of which is connected to the upper brake pump and the other end is connected to the lower brake pump to conduct the oil circuit between the upper brake pump and the lower brake pump.

[0004] Common ways to connect the oil pipe to the brake upper pump / brake lower pump are:

[0005] 1. Straight-through connector: generally includes an olive head, a straight-through sleeve, a straight-through oil needle and an O-ring that are sleeved on the oil pipe. When in use, insert one end of the straight-through oil needle into the oil pipe, and sleeve the straight-through sleeve (such as threaded connection) on the straight-through oil needle, and fix the other end (such as threaded connection) on the brake upper pump / brake lower pump to achieve connection.

[0006] 2. Direct connection method: generally includes an olive head, a rubber sleeve, a direct connection pressing screw and an oil needle which are sleeved on the oil pipe. When in use, insert the straight oil needle into the oil pipe, and then insert the oil pipe and the oil needle into the brake upper pump / brake lower pump together, and then fix the direct connection pressing screw to the brake upper pump / brake lower pump (such as threaded connection) to achieve the connection.

[0007] 3. Five-wire joint method: generally includes an olive head and a direct-connection sleeve sleeved on the oil pipe, a five-wire joint body and an oil needle. Insert the oil needle into the five-wire joint body, then align the oil needle and insert it into the oil pipe, then fix the direct-connection sleeve and the first-slim joint body (such as threaded connection) to achieve connection.

[0008] Prior art example 1, referring to patent document CN217673048U, discloses an internally routed hydraulic brake handle connection mechanism with an oil sealing film, which includes a brake handle seat and an oil pipe, a hydraulic chamber is opened in the brake handle seat, a piston is arranged in the hydraulic chamber, an oil pipe interface connected to the hydraulic chamber and a brake handle wrench for driving the piston to reciprocate is provided on the brake handle seat, the oil pipe is filled with hydraulic oil, and an end portion of the oil pipe is provided with an end head assembly which can be inserted into the oil pipe interface, the end head assembly includes an oil hole connected to the oil pipe, an oil sealing film is fixed to the end portion of the end head assembly, the oil sealing film covers the oil hole, and the oil sealing film faces the hydraulic chamber, when the brake handle wrench is pressed, the piston moves and applies pressure to the oil sealing film, and when the pressure breaks through the oil sealing film, the oil pipe and the hydraulic chamber are connected to each other.

[0009] Combining the existing connection methods and the structural solution in Example 1, both have olive head components, and the olive head needs to be squeezed and deformed after being put on the oil pipe to hold the oil pipe tightly, while also making the oil pipe and the oil needle fit tightly.

[0010] The above-mentioned oil pipe connection method requires special equipment during actual disassembly and assembly, such as technical example 2, referring to patent document TWI758849B, which discloses an oil pipe needle insertion device of the present invention, including: a body, a positioning mechanism and a push-and-pull member. The positioning mechanism is arranged on the body. The positioning mechanism includes a support component and a quick-pressing component, and the support component is movably connected to the quick-pressing component. The push-and-pull member is movably arranged on the body.

[0011] In summary, it can be inferred that the existing oil pipe connection method has certain defects, such as: 1. Disassembly and assembly are troublesome, especially for ordinary users without the help of special equipment. It is difficult to complete the operation. Even with the assistance of equipment, the entire operation process is not simple, and the function of quick disassembly and quick replacement cannot be realized. Once the oil circuit is blocked or the oil circuit is maintained, it will cause great trouble to the user. 2. Parts such as olive heads are generally disposable parts when used. Once disassembled and assembled, new parts need to be replaced, which leads to increased economic costs, and the oil pipe may be damaged when the olive head is pressed. Summary of the invention

[0012] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a quick-release oil pipe joint assembly in a brake oil circuit.

[0016] Also included are:

[0017] A quick-release locking sleeve having a sleeve hole, through which the soft oil pipe assembly passes, and into which the oil pipe access section is at least partially detachably inserted;

[0018] One of the oil pipe access section and the quick-release locking sleeve is provided with a plurality of notches to form an elastic chuck section with a variable diameter; the other of the oil pipe access section and the quick-release locking sleeve is provided with an extrusion portion, which can abut against the elastic chuck section and cause the elastic chuck section to shrink, so that the shrunken elastic chuck section clamps the soft oil pipe assembly.

[0019] A connection method for a quick-release locking sleeve and a hard oil pipe joint is that one of the quick-release locking sleeve and the oil pipe access section has an internal thread, and the other of the quick-release locking sleeve and the oil pipe access section has an external thread, and the internal thread and the external thread form a threaded fit with each other to achieve a detachable connection between the oil pipe access section and the quick-release locking sleeve.

[0020] Another connection method between the quick-release locking sleeve and the hard oil pipe joint is that a buckle groove is provided on one of the quick-release locking sleeve and the oil pipe access section, and a convex buckle is provided on the other, and the convex buckle can be inserted into the buckle groove to realize a detachable connection between the oil pipe access section and the quick-release locking sleeve.

[0021] Another connection method between the quick-release locking sleeve and the hard oil pipe joint is that the quick-release locking sleeve and the oil pipe access section are both provided with corresponding threaded holes, and fasteners are inserted into the threaded holes to achieve a detachable connection between the oil pipe access section and the quick-release locking sleeve.

[0022] The preferred structural scheme of the soft oil pipe assembly in the utility model is that the soft oil pipe assembly includes a soft oil pipe body, a hard oil needle and a plurality of sealing rings;

[0023] The hard oil needle is at least partially inserted into the soft oil pipe body;

[0024] A plurality of sealing grooves are provided on the outer wall of the hard oil needle, the sealing ring is arranged in the sealing groove, and the sealing ring abuts against the inner wall of the oil pipe access section.

[0025] The preferred structure of the hard oil needle is that the hard oil needle has a plurality of cones, and the cones can abut against the soft oil pipe body to form an interference fit.

[0026] More specifically, the extrusion portion has a first inclined end surface that gradually expands from back to front, and the elastic clamp section has a second inclined end surface that gradually expands from back to front. The first inclined end surface can abut against the second inclined end surface to form an interference fit.

[0027] Preferably, the length of the first inclined end surface is greater than the length of the second inclined end surface.

[0028] Furthermore, the sleeve hole has a large diameter hole section and a small diameter hole section, the large diameter hole section forms a clearance fit with the oil pipe access section, the small diameter hole section forms an interference fit with the oil pipe access section, and the extrusion portion is located in the small diameter hole section.

[0029] Preferably, the rear end of the quick-release locking sleeve extends inwardly to form a stop ring, and the stop ring can abut against the rear end of the elastic clamp section to form a limit stop fit.

Especially in the tense racing competition, once the oil circuit fails, it can be repaired and replaced at the fastest speed, and the fault can be quickly eliminated, so as to quickly return to the competition, effectively helping the players to improve their performance.

[0033] 3. The structure of the elastic chuck section is more reasonable. When locking, the connection is stable and reliable enough and not easy to disengage. When the elastic chuck section acts on the soft oil pipe body to clamp it, the force is more balanced and the deformation is small, thereby ensuring that the oil pipe oil channel has a stable shape to keep the oil channel unobstructed.

[0034] Fourth, the olive head structure has been eliminated, and no damage will be caused to the parts during the disassembly and assembly process, so non-destructive repeated disassembly and assembly and reuse operations can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments are only specific descriptions of the present invention, and their purpose is to allow those skilled in the art to better understand the technical solution of the present invention, and should not be regarded as limiting the present invention.

[0053] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] Reference Figures 1 to 16A quick-release oil pipe joint assembly in a brake oil circuit comprises: a hard oil pipe joint 1, which has an oil pipe access section 12, and a joint oil circuit passage 101 is provided in the oil pipe access section 12; the hard oil pipe joint 1 is integrally formed with a brake upper pump 6 housing, or the hard oil pipe joint 1 is assembled into one body with the brake upper pump 6 housing; a soft oil pipe assembly 2, which has an oil pipe oil circuit passage 21, and the soft oil pipe assembly 2 is at least partially detachably inserted into the joint oil circuit passage 101, so that the oil pipe oil circuit passage 21 and the joint oil circuit passage 101 are connected to each other, and there is an insertion and removal gap 22 between the soft oil pipe assembly 2 and the oil pipe access section 12.

[0056] In actual application, when the direct connection mode is selected, the structural scheme adopted is that the hard oil pipe joint 1 and the housing of the brake upper pump 6 are integrally formed; when the five-wire joint mode or the straight-through joint mode is selected, the structural scheme adopted is that the hard oil pipe joint 1 and the housing of the brake upper pump 6 are assembled into one. Thus, it can meet the use requirements of most brake oil circuits on the market, and the specific method adopted by the user is not specifically limited here.

[0057] When the five-wire joint method is selected, a ball-shaped joint section 11 is also formed on the hard oil pipe joint 1. The ball-shaped joint section 11 is used to connect with the brake upper pump 6 / brake lower pump 7. The connection method is similar or consistent with the prior art and will not be repeated here.

[0058] It is worth mentioning that it also includes:

[0059] A quick-release locking sleeve 3, which has a sleeve hole 31, through which the soft oil pipe assembly 2 passes, and the oil pipe access section 12 is at least partially detachably inserted into the sleeve hole 31;

[0060] A plurality of notches 131 are provided on one of the oil pipe access section 12 and the quick-release locking sleeve 3 to form an elastic chuck section 13 with a variable diameter; an extrusion portion 3121 is provided in the other of the oil pipe access section 12 and the quick-release locking sleeve 3, and the extrusion portion 3121 can abut against the elastic chuck section 13 and cause the elastic chuck section 13 to shrink, so that the shrunken elastic chuck section 13 clamps the soft oil pipe assembly 2.

[0061] The above content is the basic structural solution of the utility model. Compared with the prior art, it eliminates the olive head component.

[0062] The operating principle of quick assembly is: refer to Figure 7 to Figure 9First, the quick-release locking sleeve 3 is put on the soft oil pipe assembly 2, and then the soft oil pipe assembly 2 is inserted into the joint oil passage 101, and then the oil pipe access section 12 is inserted into the quick-release locking sleeve 3 to achieve the connection between the two. During the connection process between the quick-release locking sleeve 3 and the oil pipe access section 12, the extrusion portion 3121 gradually abuts against the elastic clamp section 13 (eliminating the insertion and extraction gap 22) and drives the elastic clamp section 13 to contract, and the contracted elastic clamp section 13 clamps the soft oil pipe assembly 2.

[0063] The operating principle of quick disassembly is: refer to Figure 7 to Figure 9 First, the connection between the quick-release locking sleeve 3 and the oil pipe access section 12 is released and separated. After the separation, the extrusion portion 3121 and the elastic clamp section 13 are also separated accordingly and the mutual force is eliminated. The elastic clamp section 13 expands outward and returns to its original shape by relying on its own elastic restoring force, and the plug-in gap 22 is re-formed at the same time. At this time, the user can apply force to the soft oil pipe assembly 2 to directly remove it from the oil pipe oil passage 21.

[0064] It should be noted that the structural scheme of the present invention can achieve at least the following effects: 1. The hard oil pipe joint 1 and the soft oil pipe assembly 2 can be assembled and disassembled by itself without the aid of special equipment; 2. The olive head structure is eliminated, and no damage is caused to the parts during the disassembly process, so non-destructive repeated disassembly and assembly operations can be achieved; 3. The disassembly and assembly operations are simple, convenient and fast, which can greatly shorten the operation time and achieve the effect of quick disassembly and assembly.

[0065] Preferably, the hard oil pipe joint 1 is made of stainless steel or aluminum alloy, etc., and has a joint oil passage 101 inside, and has a certain elastic force itself, and is opened with a matching notch 131 to form an elastic chuck section 13 with a variable diameter.

[0066] As a preferred structure, when the five-wire joint mode is selected, the sleeve hole 31 has a large diameter hole section 311 and a small diameter hole section 312, the large diameter hole section 311 forms a clearance fit with the oil pipe access section 12, the small diameter hole section 312 forms an interference fit with the oil pipe access section 12, and the extrusion portion 3121 is located in the small diameter hole section 312. More specifically, the extrusion portion 3121 has a first inclined end face 3122 that gradually expands from back to front, and the elastic clamp section 13 has a second inclined end face 132 that gradually expands from back to front, and the first inclined end face 3122 can abut against the second inclined end face 132 and form an interference fit.

[0067] In the front process of the oil pipe access section 12 being inserted into the sleeve hole 31, the elastic chuck section 13 is opposite to the large diameter hole section 311, and there is a gap between the two, so that the insertion can continue to be smoothly inserted forward; in the rear process of the oil pipe access section 12 being inserted into the sleeve hole 31, the elastic chuck section 13 is opposite to the small diameter hole section 312 (that is, the first inclined end face 3122 is against the second inclined end face 132, and as the insertion depth increases, the contact area between the first inclined end face 3122 and the second inclined end face 132 also increases accordingly), and an interference fit is formed between the two, so that the small diameter hole section 312 acts on the elastic chuck section 13, so that the elastic chuck is forced to shrink. Similarly, when the direct connection method is selected, the large diameter hole section 311 and the small diameter hole section 312 are formed in the oil pipe access section 12, which can play the same role on the elastic chuck section 13, and will not be repeated here.

[0068] Preferably, the length of the first inclined end face 3122 is greater than the length of the second inclined end face 132, which is a structural redundancy design to improve the reliability, stability and safety of the system and prevent the occurrence of unsmooth plugging and unplugging due to over-tight fitting.

[0069] Preferably, refer to Figure 6 The rear end of the quick-release locking sleeve 3 extends inward to form a stop ring 313, and the stop ring 313 can abut against the rear end of the elastic clamp section 13 to form a limit stop fit to prevent the insertion transition from causing damage to the components.

[0070] Embodiment 2

[0071] Based on the structure of the first embodiment, there are various ways to detachably connect the quick-release locking sleeve 3 and the hard oil pipe joint 1. This embodiment provides multiple preferred ways, which are as follows:

[0072] 1. Threaded connection method: refer to Fig.12 One of the quick-release locking sleeve 3 and the oil pipe access section 12 has an internal thread 314, and the other of the quick-release locking sleeve 3 and the oil pipe access section 12 has an external thread 121. The internal thread 314 and the external thread 121 form a threaded fit with each other to achieve a detachable connection between the oil pipe access section 12 and the quick-release locking sleeve 3.

[0073] For example, when a five-wire joint connection is used, the quick-release locking sleeve 3 has an internal thread 314, and the oil pipe access section 12 has an external thread 121. When a direct connection is used, the quick-release locking sleeve 3 has an external thread 121, and the oil pipe access section 12 has an internal thread 314.

[0074] 2. Buckle connection method: refer to Fig.12 A buckle groove 315 is provided on one of the quick-release locking sleeve 3 and the oil pipe access section 12, and a convex buckle 122 is provided on the other. The convex buckle 122 can be inserted into the buckle groove 315 to realize a detachable connection between the oil pipe access section 12 and the quick-release locking sleeve 3.

[0075] 3. Connection method of connector: refer to Fig.13 The quick-release locking sleeve 3 and the oil pipe access section 12 are both provided with corresponding threaded holes 4, and fasteners 41 (such as screws) are connected in the threaded holes 4 to achieve a detachable connection between the oil pipe access section 12 and the quick-release locking sleeve 3.

[0076] The above three methods are preferred solutions. There are no special limitations on more feasible detachable connection methods, such as magnetic connection methods.

[0077] Embodiment 3

[0078] Reference Figure 2 to Figure 9 In this embodiment, the preferred structural scheme of the soft oil pipe assembly 2 is as follows: the soft oil pipe assembly 2 includes a soft oil pipe body 201, a hard oil needle 202 and a plurality of sealing rings 203;

[0079] The hard oil needle 202 is at least partially inserted into the soft oil pipe body 201;

[0080] A plurality of sealing grooves 2021 are provided on the outer wall of the hard oil needle 202, and the sealing ring 203 is arranged in the sealing groove 2021, and the sealing ring 203 abuts against the inner wall of the oil pipe access section 12 to close the fitting gap, thereby achieving a sealed fit between the hard oil needle 202 and the oil pipe access section 12 and preventing the brake oil from leaking therebetween.

[0081] The preferred structure of the hard oil needle 202 is that the hard oil needle 202 has a plurality of cones 2022, and the cones 2022 can abut against the soft oil pipe body 201 and form an interference fit to provide a certain insertion and extraction force, so that the soft oil pipe body 201 and the hard oil needle 202 are not easily separated under the action of external force, and maintain stability.

[0082] It should be noted that the hard oil needle 202 in this embodiment is structurally different from the oil needle in the prior art. Specifically, it is formed with a sealing groove 2021 and cooperates with a sealing ring 203, which can provide a sealing function during connection while achieving the basic function of the original oil needle.

[0083] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0084] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
