Description

Technical Field

[0001] The utility model relates to the technical field of joint ferrules, and more specifically, to a hydraulic ferrule with a pre-tightening mechanism. Background Art

[0002] The hydraulic ferrule with a pre-tightening mechanism is a specially designed hydraulic connector. Its built-in pre-tightening mechanism can pre-apply a tightening force during the installation process to ensure a tight connection between the ferrule and the pipe, effectively preventing liquid leakage. This design is achieved through a specific mechanical structure or device, so that the ferrule can fit tightly to the pipe under the action of hydraulic pressure, and is suitable for hydraulic systems that require high sealing and stability. When the existing hydraulic ferrule is connected to the hydraulic pipe, a through groove design and a threaded connection are used. Although it can ensure sealing and stability, it is quite cumbersome during installation and disassembly. It needs to be rotated and adjusted multiple times during installation, which affects work efficiency. Therefore, a hydraulic ferrule with a pre-tightening mechanism is proposed to solve the above problems. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a hydraulic ferrule with a pre-tightening mechanism, which has the advantages of quick disassembly and installation.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydraulic ferrule with a pre-tightening mechanism, comprising a hydraulic ferrule, a nut 1 is fixedly installed on the outer surface of the hydraulic ferrule, a hydraulic pipe is movably sleeved inside the nut 1, a fixed groove is provided inside the hydraulic ferrule, and a fixed sleeve is movably installed inside the fixed groove, a spring 1 is fixedly installed inside the fixed sleeve, a wedge block is fixedly installed on one end of the spring 1, and a sliding groove is provided on the outer surface of the nut 1.

[0005] As a preferred technical solution of the utility model, a limiting groove is provided inside the fixing sleeve, a limiting block is movably installed inside the limiting groove, a sealing ring is fixedly installed at one end of the limiting block, and a spring 2 is fixedly installed on the right side of the sealing ring.

[0006] As a preferred technical solution of the utility model, the wedge blocks and springs are arranged in groups of two, and there are two groups on the outer surface of the fixing sleeve.

[0007] As a preferred technical solution of the utility model, a nut 2 is fixed to the outer surface of the hydraulic ferrule, and the nut 2 presents two shapes of the same size at both ends of the hydraulic ferrule.

[0008] As a preferred technical solution of the utility model, the spring 2 presents four shapes of the same size, and the spring 2 is made of stainless steel.

[0009] As a preferred technical solution of the utility model, the limiting grooves and limiting blocks are arranged in groups of two, with a total of four groups on the outer surface of the fixing sleeve.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. Compared with the traditional hydraulic ferrule, the hydraulic ferrule of the utility model cooperates between the wedge block, the spring and the slide groove, so as to facilitate the rapid fixing, installation and removal of the hydraulic pipe, thereby ensuring the tight connection between the hydraulic ferrule and the hydraulic pipe, providing excellent sealing performance for the system. Its strong sealing ability effectively prevents hydraulic leakage, ensures the stable operation of the hydraulic system, and avoids potential safety risks caused by leakage. The installation and removal process of the hydraulic ferrule is very convenient, without the need for complicated tools and techniques, making the maintenance and replacement work faster and more efficient, which not only reduces downtime and improves production efficiency, but also saves a lot of maintenance costs for the enterprise.

[0012] 2. Compared with the traditional hydraulic ferrule, the utility model facilitates the rapid fixation of the sealing ring through the cooperation between the second spring and the limit block, thereby ensuring that the hydraulic ferrule can still operate stably under high pressure and high speed.

When the hydraulic pipe 2 needs to be disassembled, the wedge block 5 is squeezed into the inside of the fixing sleeve 4 through the inside of the slide groove 11, and then the hydraulic pipe 2 is screwed out of the inside of the nut 3, thereby completing the assembly and disassembly of the hydraulic pipe 2.

[0023] Install the hydraulic pipe 2 on the outer surface of the hydraulic ferrule 1, hold the hydraulic pipe 2, and slowly screw the hydraulic pipe 2 into the nut 3, drive the fixing sleeve 4 to slowly enter the fixing groove 12 through the hydraulic pipe 2, and squeeze the wedge 5 through the nut 3, so that the wedge 5 slowly enters the fixing sleeve 4. When the wedge 5 reaches the position of the slide groove 11 inside the nut 3, the wedge 5 is quickly fixed and popped out of the nut 3 by the squeezing force of the spring 10, and the wedge 5 is fixed by the nut 3. When the hydraulic pipe 2 needs to be disassembled, the wedge 5 is squeezed into the fixing sleeve 4 through the slide groove 11, and then the hydraulic pipe 2 is screwed out of the nut. Inside the nut 3, compared with the traditional hydraulic ferrule, the hydraulic ferrule cooperates between the wedge block 5, the spring 10 and the slide groove 11, which is convenient for fast fixing, installation and disassembly of the hydraulic pipe 2, thus ensuring a tight connection between the hydraulic ferrule 1 and the hydraulic pipe 2, providing excellent sealing performance for the system. Its strong sealing ability effectively prevents hydraulic leakage, ensures the stable operation of the hydraulic system, and avoids potential safety risks caused by leakage. The installation and disassembly process of the hydraulic ferrule 1 is very convenient, without the need for complicated tools and techniques, making maintenance and replacement work faster and more efficient, which not only reduces downtime and improves production efficiency, but also saves a lot of maintenance costs for the enterprise.

[0024] A limiting groove 6 is provided inside the fixing sleeve 4 , a limiting block 7 is movably installed inside the limiting groove 6 , a sealing ring 8 is fixedly installed at one end of the limiting block 7 , and a spring 13 is fixedly installed on the right side of the sealing ring 8 .

[0025] After the staff completes the installation of the hydraulic pipe 2, it is necessary to add a sealing plate to one end of the hydraulic pipe 2, hold the sealing ring 8 by hand, and slowly insert the sealing ring 8 into the outer surface of the hydraulic pipe 2, and rotate the sealing ring 8 on the outer surface of the hydraulic pipe 2 to slowly align the limit block 7 with the inside of the limit groove 6, and then slowly move the limit block 7 and the sealing ring 8 to the inside of the limit groove 6, and drive the limit block 7 to move inside the limit groove 6 through the sealing ring 8, and then squeeze it through the spring 2 13, and the sealing ring 8 is squeezed by the spring 2 13, so that the sealing ring 8 is fixed.

[0026] After the hydraulic pipe 2 is installed, it is necessary to add a sealing plate at one end of the hydraulic pipe 2, hold the sealing ring 8 by hand, slowly insert the sealing ring 8 into the outer surface of the hydraulic pipe 2, rotate the sealing ring 8 on the outer surface of the hydraulic pipe 2 to slowly align the limit block 7 with the inside of the limit groove 6, and then slowly move the limit block 7 and the sealing ring 8 to the inside of the limit groove 6, and drive the limit block 7 to move inside the limit groove 6 through the sealing ring 8, and then squeeze it through the spring 2 13, and squeeze the sealing ring 8 through the spring 2 13. Compared with the traditional hydraulic ferrule, the hydraulic ferrule is convenient to quickly fix the sealing ring 8 through the cooperation between the spring 2 13 and the limit block 7, so as to ensure that the hydraulic ferrule 1 can still operate stably under high pressure and high speed. At the same time, the sealing ring 8 can also effectively isolate different media to avoid mixing or reaction, thereby ensuring the working environment and stability of each medium. At the same time, its dustproof and waterproof function provides a solid protective barrier for the hydraulic system to prevent the invasion of external dust, moisture and impurities, ensure that the equipment is protected from damage and extend its service life.

[0027] The wedge blocks 5 and the springs 10 are arranged in pairs, and there are two groups on the outer surface of the fixing sleeve 4 .

[0028] Since the wedge blocks 5 and the springs 10 are arranged in pairs, there are four groups on the outer surface of the fixed sleeve 4. By providing the wedge blocks 5 and the springs 10, it is convenient to install the hydraulic pipe 2 more stably, thereby improving the installation efficiency of the hydraulic pipe 2 and the stability during use.

[0029] Among them, a nut 2 9 is fixed on the outer surface of the hydraulic ferrule 1, and the nut 2 9 presents two shapes of the same size at both ends of the hydraulic ferrule 1.

[0030] Since the nut 9 presents two shapes of the same size at both ends of the hydraulic ferrule 1, it is convenient for the nut 9 to be used in conjunction with the bolt. Through the tightening operation, a strong fastening force can be provided for the hydraulic ferrule, thereby ensuring that it fits tightly on the hydraulic pipe and is not easy to loosen or fall off.

[0031] The second springs 13 are in four shapes of the same size, and the second springs 13 are made of stainless steel.

[0032] Since the second spring 13 is made of stainless steel and presents four shapes of the same size, the sealing ring 8 is more stably fixed, thereby improving the sealing efficiency of the sealing ring 8 on the hydraulic pipe 2.

[0033] The limiting grooves 6 and the limiting blocks 7 are arranged in groups of two, and there are four groups on the outer surface of the fixing sleeve 4 .

[0034] Since the limiting grooves 6 and the limiting blocks 7 are arranged in pairs, there are four groups on the outer surface of the fixed sleeve 4. Through the cooperation between the limiting grooves 6 and the limiting blocks 7, the hydraulic pipe 2 can be quickly sealed, thereby preventing leakage at the connection of the hydraulic pipe 2 and improving the use efficiency of the hydraulic pipe 2.

[0036] The staff installs the hydraulic pipe 2 on the outer surface of the hydraulic ferrule 1, holds the hydraulic pipe 2, slowly aligns the fixing sleeve 4 on the outer surface of the hydraulic pipe 2 with the fixing groove 12 inside the nut 3, and then slowly screws the hydraulic pipe 2 into the inside of the nut 3, drives the fixing sleeve 4 to slowly enter the inside of the fixing groove 12 through the hydraulic pipe 2, and squeezes the wedge block 5 through the nut 3, so that the wedge block 5 slowly enters the inside of the fixing sleeve 4.

When the hydraulic pipe 2 needs to be disassembled, the wedge block 5 is squeezed into the inside of the fixing sleeve 4 through the inside of the slide groove 11, and then the hydraulic pipe 2 is screwed out of the inside of the nut 3, thereby completing the assembly and disassembly of the hydraulic pipe 2.

[0037] After the staff completes the installation of the hydraulic pipe 2, it is necessary to add a sealing plate to one end of the hydraulic pipe 2, hold the sealing ring 8 by hand, and slowly insert the sealing ring 8 into the outer surface of the hydraulic pipe 2, and rotate the sealing ring 8 on the outer surface of the hydraulic pipe 2 to slowly align the limit block 7 with the inside of the limit groove 6, and then slowly move the limit block 7 and the sealing ring 8 to the inside of the limit groove 6, and drive the limit block 7 to move inside the limit groove 6 through the sealing ring 8, and then squeeze it through the spring 2 13, and the sealing ring 8 is squeezed by the spring 2 13, so that the sealing ring 8 is fixed.
