The clamping block 7 penetrates through the inner wall of the female hard pipe fitting 1, and a clamping groove 6 is formed on the surface of the male hard pipe fitting 2, and the clamping block 7 is snap-fitted with the clamping groove 6.

[0028] The plugging assembly includes a limiting block 9, the limiting block 9 is fixedly connected inside the female hard pipe fitting 1, a connecting cylinder 10 is slidably connected inside the limiting block 9, a joint core head 11 is fixedly connected to one end of the connecting cylinder 10 away from the limiting block 9, a first spring 12 is arranged on the surface of the connecting cylinder 10, and both ends of the first spring 12 are fixedly connected to the limiting block 9 and the joint core head 11 respectively. A first sealing ring 13 is arranged on the surface of the joint core head 11, a plurality of first through grooves 17 are formed on the surface of the limiting block 9, and a plurality of second through grooves 18 are formed on the surface of the connecting cylinder 10.

[0029] The number of the clamping grooves 6, the clamping blocks 7, the grooves 8, and the second springs 19 is three, and they are symmetrically arranged on the outer sides of the corresponding female hard pipe fitting 1 and male hard pipe fitting 2 respectively.

[0030] The number of the plugging assemblies is two, and they are symmetrically arranged inside the corresponding female hard pipe fitting 1 and male hard pipe fitting 2 respectively.

[0031] Three second sealing rings 14 are arranged on the surface of the male hard pipe fitting 2, a first sealing gasket 15 is fixedly connected inside the female hard pipe fitting 1, and a second sealing gasket 16 is fixedly connected to the surface of the male hard pipe fitting 2.

[0032] Nuts 3 are fixedly connected to the surfaces of both the female hard pipe fitting 1 and the male hard pipe fitting 2.

[0033] When using this device, first connect the female fitting 1 of the rigid pipe joint and the male fitting 2 of the rigid pipe joint to the corresponding hydraulic brake rigid pipes respectively. Then, push the male fitting 2 of the rigid pipe joint to insert the male fitting 2 of the rigid pipe joint into the inside of the nut 3. The male fitting 2 of the rigid pipe joint squeezes the inclined surface of the clamping block 7, causing the clamping block 7 to slide inside the female fitting 1 of the rigid pipe joint. The clamping block 7 squeezes the second spring 19. The male fitting 2 of the rigid pipe joint drives the corresponding limiting block 9, connecting cylinder 10, joint core head 11, first spring 12, and first sealing ring 13 to move. When the two come into contact, the joint core head 11 slides inside the corresponding female fitting 1 of the rigid pipe joint and the male fitting 2 of the rigid pipe joint. The joint core head 11 squeezes the first spring 12. The joint core head 11 drives the connecting cylinder 10 to slide inside the limiting block 9. At the same time, it is sealed through the second sealing ring 14, first sealing gasket 15, and second sealing gasket 16 to prevent hydraulic oil leakage. The clamping block 7 is clamped with the corresponding card slot 6 to limit and fix the male fitting 2 of the rigid pipe joint.

[0034] The hydraulic oil flows through the connecting cylinder 10, the first through groove 17, the second through groove 18, and the gap between the joint core head 11 and the corresponding female fitting 1 of the rigid pipe joint and the male fitting 2 of the rigid pipe joint, facilitating the circulation of the hydraulic oil.

[0035] When it is necessary to disassemble and maintain the hydraulic brake rigid pipe, just press the movable ring 5 into the inside of the sleeve 4, so that the movable ring 5 squeezes the inclined surface of the groove 8, causing the groove 8 to drive the clamping block 7 to move, facilitating the release of the clamping connection between the clamping block 7 and the card slot 6. At the same time, the joint core head 11 will block the corresponding female fitting 1 of the rigid pipe joint or the male fitting 2 of the rigid pipe joint under the action of the first spring 12, and is sealed through the first sealing ring 13. The two joint core heads 11 squeeze each other, and a reverse force will be applied to the limiting block 9 during the squeezing process, facilitating the separation of the female fitting 1 of the rigid pipe joint and the male fitting 2 of the rigid pipe joint, improving the separation efficiency of the device and facilitating its disassembly.

[0036] Furthermore, through the clamping connection between the card slot 6 and the clamping block 7, it is convenient to fix and disassemble the female fitting 1 of the rigid pipe joint and the male fitting 2 of the rigid pipe joint. When the hydraulic brake rigid pipe fails, it can be quickly disassembled and repaired. Compared with threaded connection or flange connection, it can be disassembled and installed without using tools, improving the disassembly efficiency of the device, facilitating its overhaul and maintenance, and improving the maintenance efficiency.

[0037] The device is sealed through the first sealing ring 13, the second sealing ring 14, the first sealing gasket 15, and the second sealing gasket 16. Through elastic deformation, the unevenness of the joint surface of the parts is filled, the leakage channel is cut off, the leakage resistance is increased, and the sealing effect of the device is improved.

[0038] Through the settings of the first through groove 17 and the second through groove 18, it is convenient for the hydraulic oil to flow from the first through groove 17 and the second through groove 18, which is beneficial to improving the fluidity of the hydraulic oil when the device is in use and enhancing the practicability of the device.

[0039] Working principle: When using this device, first connect the female hard pipe joint 1 and the male hard pipe joint 2 to the corresponding hydraulic brake hard pipes respectively. Then, push the male hard pipe joint 2 to insert the male hard pipe joint 2 into the inside of the nut 3. The male hard pipe joint 2 squeezes the inclined surface of the block 7, causing the block 7 to slide inside the female hard pipe joint 1. The block 7 squeezes the second spring 19. The male hard pipe joint 2 drives the corresponding limit block 9, connecting cylinder 10, joint core 11, first spring 12 and first sealing ring 13 to move. When the two are in contact, the joint core 11 slides inside the corresponding female hard pipe joint 1 and male hard pipe joint 2. The joint core 11 squeezes the first spring 12. The joint core 11 drives the connecting cylinder 10 to slide inside the limit block 9. At the same time, sealing is carried out through the second sealing ring 14, first sealing gasket 15 and second sealing gasket 16 to prevent the leakage of hydraulic oil. The block 7 is clamped with the corresponding card slot 6 to limit and fix the male hard pipe joint 2.

[0040] The hydraulic oil flows through the connecting cylinder 10, the first through groove 17, the second through groove 18 and the gap between the joint core 11 and the corresponding female hard pipe joint 1 and male hard pipe joint 2, which is convenient for the flow of the hydraulic oil.

[0041] When it is necessary to disassemble and maintain the hydraulic brake hard pipe, just press the movable ring 5 into the inside of the sleeve 4, so that the movable ring 5 squeezes the inclined surface of the groove 8, causing the groove 8 to drive the block 7 to move, which is convenient for releasing the clamping connection between the block 7 and the card slot 6. At the same time, the joint core 11 will block the corresponding female hard pipe joint 1 or male hard pipe joint 2 under the action of the first spring 12. At the same time, sealing is carried out through the first sealing ring 13. The two joint cores 11 squeeze each other, and a reverse force will be applied to the limit block 9 during the squeezing process, which is convenient for separating the female hard pipe joint 1 and the male hard pipe joint 2 and improving the separation efficiency of the device, facilitating its disassembly.

[0042] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the technical field, various changes can be made without departing from the gist of the present invention.
