Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic brake hard pipe assembly joints, in particular to a high-seal liner core joint structure used for hydraulic brake hard pipe assemblies. Background Art

[0002] Automobile brake lines include steel pipes and flexible hoses, which are connected together with joints. Their function is to transfer the brake fluid obtained from the master cylinder to the brakes of each wheel. The high-sealing liner joint structure used in the hydraulic brake hard pipe assembly mainly focuses on ensuring high sealing and stability at the connection. Usually, in order to ensure high sealing of the joint part, a sealing ring is set at the joint part to enhance the stability of the seal.

[0003] A hydraulic brake hard pipe quick connector disclosed in the patent application with reference publication number CN210372461U includes a valve body seat, a quick connector core, a sealing ring, a brake steel pipe, a locking nut and a retaining ring; the utility model has a reasonable and simple structure, low production cost, convenient installation, and complete functions. The brake steel pipe using the quick connector is simple to assemble, and the steel pipe is not subjected to force and distortion after assembly, thereby improving production efficiency. During assembly, the special-shaped rubber sealing ring is assembled into the quick connector core, and the brake steel pipe is fixed to the quick connector core by the locking nut. The brake steel pipe adopts a trumpet shape and is compressed and sealed by the locking nut. The quick connector seal mainly relies on the special-shaped rubber sealing ring to cooperate with the valve body seat for sealing, and the conical surface of the quick connector core assists in sealing. The retaining ring compresses the locking nut to form a set compression force to produce an auxiliary sealing effect. At the same time, the special-shaped rubber sealing ring deforms and expands under the pressure of the left hydraulic pressure to enhance the sealing energy of the sealing ring.

[0004] As shown in the above-mentioned prior art, the joint structure of the existing hydraulic brake hard pipe assembly will be provided with a rubber sealing ring to cooperate with the valve body seat to seal to enhance the sealing performance. As time goes by, the rubber sealing ring will wear, age, harden and lose its elasticity. The signs of wear will eventually cause the sealing ring to fail to achieve the expected sealing effect. The sealing ring in the existing joint structure is tightly nested, making it inconvenient to replace it.

[0005] Therefore, it is necessary to provide a high-sealing liner core joint structure for a hydraulic brake hard pipe assembly to solve the above technical problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides two technical solutions:

[0029] Figures 1 to 4 A first embodiment is shown: a high-seal liner core joint structure for a hydraulic brake hard pipe assembly, comprising:

[0030] Quick connector 1;

[0031] The rubber sealing ring 2 is detachably installed on one side of the quick connector 1 near the interface;

[0032] A push assembly is provided with a push rubber seal ring 2 inside the quick connector 1 to assist the push assembly to leave the quick connector 1 so as to facilitate replacement of the rubber seal ring 2 .

[0033] The push assembly comprises a first slide groove 3 symmetrically arranged on the inner wall of the quick connector 1 , a push rod 4 is slidably connected to the inner wall of the first slide groove 3 , and one end of the push rod 4 close to the rubber sealing ring 2 contacts the rubber sealing ring 2 .

[0034] A moving part 5 is fixed to one end of the push rod 4 away from the rubber sealing ring 2 , a spring 6 is fixed to one end of the moving part 5 away from the push rod 4 , and one end of the spring 6 away from the moving part 5 is fixed to the inner wall of the first sliding groove 3 .

[0035] Elliptical slide grooves 7 are symmetrically and obliquely provided on both sides of the moving member 5 , and sliding posts 8 are slidably connected to the inner walls of the two elliptical slide grooves 7 , and the two sliding posts 8 are connected by a push block 9 .

[0036] A second slide groove 10 is provided on the inner wall of the quick connector 1 corresponding to the push block 9 , the first slide groove 3 is communicated with the second slide groove 10 , and the push block 9 is slidably connected with the inner wall of the second slide groove 10 .

[0037] This application facilitates the replacement of the rubber sealing ring 2 by providing a push assembly, prevents the inconvenience in replacing the rubber sealing ring 2, and prevents leakage caused by aging of the rubber sealing ring 2. Timely replacement of the rubber sealing ring 2 ensures the effectiveness of the rubber sealing ring 2 and the sealing of the joint structure.

[0038] Figure 1 A second embodiment is shown, which differs from the first embodiment mainly in that:

[0039] A pressing block 11 is fixed to one end of the push block 9 which is away from the moving member 5 , and an anti-slip groove is provided on the pressing block 11 .

[0040] This application provides an anti-slip groove on the pressing block 11 to improve the experience of using the pressing block 11 to assist in removing the rubber sealing ring 2.

[0041] Working principle:

[0042] The liner core joint of the quick connector 1 is configured according to the prior art and will not be described in detail.

[0043] Use the quick connector 1 to connect the hydraulic brake pipe; over time, the rubber sealing ring 2 set to ensure the sealing of the connection will age and wear, and needs to be replaced in time. At this time, use the quick connector 1 to quickly disassemble the connected pipe, and then press the pressing block 11 to make the push block 9 move in the second slide groove 10 toward the end close to the first slide groove 3, thereby driving the slide columns 8 on both sides to move in the elliptical slide groove 7, and driving the moving part 5 to push the push rod 4 to move the push rod 4 in the first slide groove 3, and the spring 6 is stretched. When the slide column 8 moves to the end of the elliptical slide groove 7 close to the spring 6, the push rod 4 pushes the rubber sealing ring 2 to the direction away from the first slide groove 3, thereby facilitating the removal of the rubber sealing ring 2 from the inside of the quick connector 1.

[0044] When the pressing block 11 is released, the spring 6 rebounds, returning the moving part 5 and the push rod 4 to their original positions, and the push block 9 then drives the pressing block 11 to return to its original position, so that a new rubber sealing ring 2 can be placed inside the quick connector 1 to reconnect the pipeline.
