Description

Technical Field

[0001] This utility model relates to a hydraulic brake, specifically a split-type hydraulic brake installation structure. Background Technology

[0002] In modern vehicle braking systems, hydraulic brakes are a common and effective braking method, and the reliability and ease of installation of their structure significantly impact the overall performance of the braking system. Traditional split-type hydraulic brake installation structures typically employ a spur thread connection (tightening clockwise and loosening counter-clockwise), assembling the braking system through a direct connection between the hydraulic hose and the main body. This traditional structure has several major drawbacks in practical applications:

[0003] Traditional connecting sleeves typically use a direct sleeve connection method, which requires inserting the copper sleeve into the oil pipe and ensuring that the oil pipe is fully inserted into the bottom of the mounting hole. This process is quite cumbersome in actual operation, especially when space is limited or operating conditions are complex, resulting in low installation efficiency.

[0004] Because of the orthogonal structure, if the oil pipe is not fully inserted into the bottom of the mounting hole during installation, the connection between the copper sleeve and the oil pipe may not be tight, which may lead to loosening of the connection. This not only increases the difficulty of repairing the braking system, but may also pose a safety hazard.

[0005] In traditional installation methods, if the copper bushing is not evenly stressed during the connection process, it may lead to poor sealing and increase the risk of oil leakage. Oil leakage not only affects the performance of the braking system, but may also damage other parts of the vehicle.

[0006] Because the orthogonal structure is prone to irregular deformation of the copper bushing during disassembly, especially when the oil pipe is not fully inserted into the bottom of the mounting hole, the disassembly process becomes more complicated and laborious. This increases the difficulty and time cost of maintenance when the oil pipe needs to be replaced. Utility Model Content

[0007] To address the aforementioned issues, this invention provides a split-type hydraulic brake installation structure. By employing a reverse thread structure and an optimized connection method, it effectively solves the problems of traditional structures in terms of installation convenience, connection firmness, and sealing performance, significantly improving the overall performance and reliability of hydraulic brake installation.

[0008] This utility model is achieved through the following technical solution: a split-type hydraulic brake mounting structure, comprising:

[0009] An oil pipe is connected to the main body. One end of the oil pipe is provided with a copper needle, and one end of the copper needle is exposed outside the oil pipe and forms a reverse thread section.

[0010] A connecting sleeve having an internal threaded connection section, wherein the connecting sleeve engages with a reverse threaded section on the oil pipe via the internal threaded connection section;

[0011] A clamping screw, fitted onto the outside of the oil pipe, is used to clamp the copper needle to the connecting sleeve.

[0012] As a preferred technical solution, one end of the copper needle forms an insertion section, and the copper needle is inserted into the oil hole of the oil pipe through the insertion section. The insertion section is provided with multiple undercut steps along the length of the insertion section, and the copper needle is sealed and assembled with the oil pipe through the multiple undercut steps.

[0013] As a preferred technical solution, the connecting sleeve forms a fitting cavity at one end relative to the reverse thread section, the internal thread connecting section is located on the bottom surface of the fitting cavity, the oil pipe and the connecting sleeve are both fitted into the fitting cavity and hidden, and are threadedly connected to the connecting sleeve by the reverse thread section.

[0014] As a preferred technical solution, the connecting sleeve is a copper sleeve, and the connecting sleeve is tightened to the copper needle by counterclockwise threading.

[0015] As a preferred technical solution, a rubber cap is also included, which is fitted onto the outside of the oil pipe. When the clamping screw is threadedly tightened with the connecting sleeve, the rubber cap is located outside the clamping screw and the connecting sleeve, serving as a sealing and protective component.

[0016] The beneficial effects of this utility model are: the reverse thread design of this utility model allows the copper sleeve and copper needle to tighten more and more during the locking process, avoiding the tedious steps of accurately inserting the oil pipe into the bottom of the installation hole in the traditional installation method, which greatly simplifies the installation operation and improves the installation efficiency.

[0017] The reverse tooth structure ensures the strength and sealing of the connection, preventing the risk of oil leakage due to loose connection and improving the overall reliability of the braking system;

[0018] When the reverse-tooth structure is locked to the main body, the tightening direction of the clamping screw will tighten the copper sleeve and copper needle more and more. During installation, there is no need to insert the oil pipe to the bottom of the installation hole. You can directly tighten the clamping screw. The installation is convenient and the oil sealing effect is better. The copper sleeve deforms in a regular manner, and it is easy to disassemble and replace when the oil pipe needs to be replaced.

[0026] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0027] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0028] like Figures 1-3 As shown, this utility model provides a split-type hydraulic brake installation structure, the specific implementation of which is as follows: First, select an oil pipe 5 of suitable length and material, and firmly connect one end of it to the main body of the braking system. A copper needle is pre-installed at one end of the oil pipe 5, with one end of the copper needle exposed outside the oil pipe 5, and a reverse-threaded section 1 is formed on its exterior. The design of this reverse-threaded section 1 allows for tightening by counterclockwise rotation during the connection process, ensuring the connection's firmness and sealing.

[0029] Subsequently, a connecting sleeve 2 matching the copper needle thread is selected, and the connecting sleeve 2 has an internal threaded connecting section 22. The connecting sleeve 2 is threadedly engaged with the reverse thread section 1 on the oil pipe 5 through the internal threaded connecting section 22 to ensure a precise fit between the two. One end of the connecting sleeve 2 forms a fitting cavity 21 relative to the reverse thread section 1, and the internal threaded connecting section 22 is located on the bottom surface of the fitting cavity 21. The oil pipe 5 and the connecting sleeve 2 are then fitted into the fitting cavity 21 as a whole, making it hidden inside, and a firm connection is achieved through the threads of the reverse thread section 1 and the connecting sleeve 2.

[0030] Next, select a suitable clamping screw 4 and fit it onto the outside of the oil pipe 5. The function of the clamping screw 4 is to further tighten the contact surface between the copper needle and the connecting sleeve 2, ensuring a tight connection and preventing oil leakage. During installation, use an 8mm open-end wrench to tighten the clamping screw 4 to the specified tightening torque of 8 N·m. Due to the reverse thread structure, the copper sleeve and copper needle will tighten further during the clamping process, eliminating the need to precisely insert the oil pipe 5 into the bottom of the mounting hole, simplifying the installation steps and improving installation efficiency.

[0031] To further enhance the sealing and protection of the connection, a rubber cap 3 is installed after the clamping screw 4 is tightened and the connecting sleeve 2 is engaged. The rubber cap 3 is fitted over the outside of the oil pipe 5, located outside the clamping screw 4 and the connecting sleeve 2, serving as a protective seal to effectively prevent external contaminants from entering the connection and extend the service life of the braking system.

[0032] In this embodiment, as Figure 4 As shown, one end of the copper needle 6 forms an insertion section. The copper needle is inserted into the oil hole of the oil pipe through the insertion section. Multiple inverted steps 61 are provided on the insertion section along the length of the insertion section. The copper needle is sealed and assembled with the oil pipe through the multiple inverted steps. The inverted steps increase the sealing performance between the copper needle and the oil pipe, ensuring the normal delivery of oil without leakage and increasing the assembly sealing performance.

[0033] The connecting sleeve 2 of this utility model is made of copper, which has good corrosion resistance and mechanical strength. Tightening the copper sleeve to the copper needle thread by counterclockwise rotation not only ensures a firm connection but also makes disassembly and replacement of the oil pipe 5 easier due to the regular deformation characteristics of the copper sleeve, reducing maintenance time and costs. The overall structural design is reasonable, and the components fit tightly together, ensuring the overall reliability and sealing performance of the braking system and avoiding oil leakage and loosening problems that may occur during installation and use of traditional orthogonal thread structures.

[0034] This utility model's split-type hydraulic brake mounting structure, through its reverse thread design and optimized connection method, achieves multiple beneficial effects such as convenient installation, firm connection, superior sealing performance, and easy maintenance and replacement. It significantly improves the overall performance and reliability of the hydraulic brake system and has broad application prospects.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
