Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pipe fitting processing, in particular to a hydraulic pipe joint assembly. Background Art

[0002] Hydraulic pipe joints are components that connect high-pressure oil pipes in hydraulic systems. Hydraulic pipe joints can be divided into hydraulic hoses, high-pressure ball valves, quick connectors, ferrule-type pipe joints, welding-type pipe joints, high-pressure hoses, transition-type pipe joints, three-way pipe joints, non-standard pipe joints, flared pipe joints, right-angle pipe joints, swivel pipe joints, quick connectors, stainless steel pipe joints, and copper joints. In hydraulic systems, both metal pipe joints and hose joints are prone to leakage.

[0003] After exploration and analysis, the following shortcomings exist in actual use:

[0004] Some existing hydraulic pipe joints have too complex structures, and the joint body is usually installed through threaded connection. Therefore, it may be affected by external factors, causing the joint body to loosen or the threads to wear, resulting in leakage, thereby affecting the working efficiency and performance of the system.

[0005] In summary, the present application now proposes a hydraulic pipe joint assembly to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a hydraulic pipe joint assembly, which can solve the problem that the joint body is usually installed through threaded connection, so it may be affected by the outside world, resulting in loosening of the joint body or wear of the threads, thereby causing leakage.

[0007] To achieve the above purpose, the utility model provides the following technical solution: a hydraulic pipe joint assembly, comprising:

[0008] A hydraulic pipe, one end of which is provided with a joint body;

[0009] The limit assembly is arranged on the hydraulic pipe and the joint body. The limit assembly includes a movable protective sleeve, a slide groove and a sliding block. The inner wall of the movable protective sleeve is fixedly installed with a sliding block, the sliding block is slidably installed inside the slide groove, and the sliding block is clamped and installed inside the clamping groove.

[0010] Preferably, an oil pipe is provided at the other end of the hydraulic pipe, and a gasket is sleeved and installed between the oil pipe and the hydraulic pipe to fill the tiny gap at the pipe connection and ensure the sealing performance.

[0011] Preferably, the oil pipe and the hydraulic pipe are fixedly installed by nuts, which has a simple structure and is convenient for disassembly at a later time.

[0012] Preferably, the second set of gaskets is installed on the hydraulic pipe. The second gasket is located between the hydraulic pipe and the joint body and fits tightly therewith, which can fill the tiny gap at the pipe connection and ensure the sealing performance. At the same time, it can play a buffering role at the pipe connection, reduce the direct contact of the metal surface, and reduce the risk of corrosion.

[0013] Preferably, the limit assembly also includes a fixed sleeve and a slot. The fixed sleeve is rotatably mounted on the hydraulic pipe, and the movable protective sleeve is arranged on the fixed sleeve. The outer wall of the fixed sleeve is provided with a slot corresponding to the sliding block, and the outer wall of the joint body is provided with a slot. The sliding block is mounted in the slot by snapping. After the joint body is fixed by threaded connection, it is limited by the limit assembly, which can enhance the stability and reliability of the joint body and prevent it from moving or loosening due to vibration or external force during operation, thereby improving the safety of the hydraulic system. Especially in high pressure or high vibration environments, the limit assembly can ensure that the joint is always in the correct position, reduce the possibility of leakage or failure, and eliminate the need for operators to frequently check and adjust the joint position, thereby reducing maintenance workload and operation complexity.

[0014] Preferably, the oil pipe, hydraulic pipe and joint body are connected to facilitate the subsequent transmission of liquid.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The hydraulic pipe joint assembly, through the coordinated use of a fixed sleeve, a movable protective sleeve, a slide groove, a clamping groove and a sliding block, can enhance the stability and reliability of the joint body after the joint body is fixed by threaded connection, and at the same time prevent it from moving or loosening due to vibration or external force during operation, thereby improving the safety of the hydraulic system. Especially in a high-pressure or high-vibration environment, the limit assembly can ensure that the joint is always in the correct position, reduce the possibility of leakage or failure, and make it unnecessary for operators to frequently check and adjust the joint position, thereby reducing the maintenance workload and operation complexity.
