Description

Technical Field

[0001] This utility model relates to the field of hydraulic hose technology, and in particular to a hydraulic hose assembly connector. Background Technology

[0002] Hydraulic hose assemblies, also known as hose assemblies, are a common auxiliary device in hydraulic systems. They consist of high-pressure steel wire braided or wound hoses and steel fittings, assembled using specialized equipment. Their main function is to connect various hydraulic components in the hydraulic system to transmit hydraulic power or transport high-pressure media such as water, gas, and oil. These assemblies are widely used in various industrial fields, such as hydraulic supports in mines, oilfield extraction, engineering construction, hoisting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, and various machine tools.

[0003] During use, hoses are connected to each other via connectors. If the filter assembly in the connector does not seal properly after installation, some of the hydraulic oil injected into the hose may bypass the filter assembly and directly enter the equipment. Alternatively, the filter may loosen due to oil impact, leading to a decrease in filtration efficiency. Furthermore, over long-term use, the filter is difficult to disassemble within the hydraulic pipeline due to oil residue buildup, making removal troublesome. Therefore, this invention provides a hydraulic hose assembly connector. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figures 1-6 The hydraulic hose assembly connector shown includes a sealing connector 10 and a connecting pipe 20. A connecting port 11 is fixedly installed on the sealing connector 10. The connecting pipe 20 is movably installed on the connecting port 11. A filter cartridge 30 is installed inside the connecting port 11. A pushing component for pushing the filter cartridge 30 is provided in the connecting port 11. The pushing component includes an arc-shaped push rod 31 for pushing the filter cartridge 30. A plurality of base holes 32 are evenly opened at the end of the connecting port 11 away from the sealing connector 10. A telescopic spring 33 is fixedly installed inside the base holes 32. The arc-shaped push rod 31 is fixedly installed in the telescopic spring 33.

[0024] When disassembly is required, the connecting pipe 20 and the connecting port 11 are rotated and disassembled. The telescopic spring 33 in the base hole 32 stores force to push the arc-shaped top rod 31. The arc-shaped top rod 31 is pushed out and acts on the mounting ring 35, so that the mounting ring 35 drives the sealing ring 36 and the filter frame out of the connecting port 11, which facilitates the disassembly and cleaning of the filter frame.

[0025] See Figure 2 — Figure 6 The bottom of the filter cylinder 30 is evenly provided with a number of filter holes 34. An installation ring 35 is fixedly installed on the outer periphery of the end of the filter cylinder 30 away from the sealing connection seat 10, and the arc-shaped top rod 31 abuts against the installation ring 35. A sealing ring 36 is fixedly installed on the installation ring 35. A sealing groove 37 that matches the size of the sealing ring 36 is provided on the connection port 11, and the sealing ring 36 moves in the sealing groove 37.

[0026] The sealing ring 36 on the mounting ring 35 is inserted into the sealing groove 37 of the connection port 11 to achieve a reinforced sealing effect at the connection, and the liquid is filtered through the filter holes 34 in the filter cylinder 30.

[0027] See Figure 2 — Figure 6 A positioning ring 21 is fixedly installed inside the connecting pipe 20. A rotating ring 22 is fixedly installed on the positioning ring 21, and the rotating ring 22 abuts against the mounting ring 35. A sealing thread 12 is provided on the outer periphery of the connecting port 11. A sealing spiral groove 23 that matches the sealing thread 12 is opened inside the connecting pipe 20.

[0028] The positioning ring 21 and the rotating ring 22 are used to abut against the mounting ring 35, and the sealing ring 36 on the mounting ring 35 is pushed into the mounting groove to strengthen the sealing effect. The rotating ring 22 strengthens the mounting ring 35 so that the filter frame inside the mounting ring 35 will not shake or shift.

[0029] The working principle of this utility model is as follows: The filter screen is placed into the connection port 11, and the mounting ring 35 on the filter plate abuts against the connection port 11. At the same time, the sealing ring 36 on the mounting ring 35 is inserted into the sealing groove 37 of the connection port 11 to achieve a reinforced sealing effect at the connection. The sealing spiral groove 23 on the connecting pipe 20 is rotated and connected to the sealing thread 12 of the connection port 11, so that the connecting pipe 20 is rotated and connected to the connection port 11. During the rotation process, the rotating ring 22 of the positioning ring 21 inside the connecting pipe 20 abuts against the mounting ring 35, pushing the mounting ring 35 to abut against the connection port 11 and seal it. When the mounting ring 35 is in contact and sealed, it drives the arc-shaped top rod 31 to compress the telescopic spring 33, so that the arc-shaped top rod 31 enters the base hole 32.

[0030] When disassembly is required, the connecting pipe 20 and the connecting port 11 are rotated to disassemble. The telescopic spring 33 in the base hole 32 stores force to push the arc-shaped top rod 31. The arc-shaped top rod 31 is pushed out and acts on the mounting ring 35, so that the mounting ring 35 drives the sealing ring 36 and the filter frame out of the connecting port 11, which facilitates the disassembly and cleaning of the filter frame.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
