[0002] A hydraulic jack is a mechanical device that uses hydraulic principles to lift and support heavy objects. It typically consists of a cylinder, piston, pump body, and valves. When the operating handle or electric pump pushes hydraulic oil into the cylinder, the oil pressure acts on the piston, causing it to rise and thus lifting the object to the desired height. Hydraulic jacks have advantages such as compact structure, high load-bearing capacity, labor-saving operation, and high safety, and are widely used in automotive repair, machinery assembly, engineering construction, and the handling and support of heavy equipment.

[0003] In existing technologies, joints are generally connected by threaded structures. However, this connection method is difficult to provide effective fixation for threaded pipes. During use, the pipes are prone to rotation due to vibration or external forces, which can lead to loosening or even leakage of the joints, affecting the sealing and safety of the system, and increasing the complexity of maintenance and repair. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a hydraulic jack hose connector that is easy to assemble. It aims to improve the existing technology where connectors are generally connected by a threaded structure.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Example 1: Refer to Figure 1 and Figure 2 An embodiment of this utility model is provided: a hydraulic jack hose connector that is easy to assemble, including a connector 1, a connecting pipe 2 connected to the rear end of the connector 1, a fixing pipe 3 provided at the front end of the connecting pipe 2, and an installation ring 4 provided on the outside of the connecting pipe 2. A fixing structure 5 is provided at the front end of the installation ring 4 and the outer side of the rear end of the connector 1. Specifically, by inserting the fixing tube 3 of the connecting tube 2 into the connector 1, fixing the connecting tube 2 with the mounting ring 4, and then fixing the angle of the mounting ring 4 on the outside of the connector 1 with the fixing structure 5, the connection between the connector 1 and the connecting tube 2 is fixed.

[0019] Reference Figure 4 The fixing structure 5 includes three sets of limiting strips 501, which are fixedly installed on the outside of the connector 1, and the mounting ring 4 has three sets of limiting grooves 502 that match the limiting strips 501 inside. Specifically, after the mounting ring 4 is installed on the outside of the connector 1 through the cooperation of the limiting strip 501 and the limiting groove 502, the limiting strip 501 and the limiting groove 502 will fix the angle of the mounting ring 4, thereby preventing the mounting ring 4 from rotating on the outside of the connector 1, and thus restricting the connecting pipe 2 to prevent the connecting pipe 2 and the fixing pipe 3 from rotating.

[0020] Reference Figure 1 The outer surface of the fixed tube 3 is provided with a threaded structure, and the rear end of the connector 1 is provided with a matching threaded structure. Specifically, the fixed tube 3 can be securely locked by screwing it into the connector 1. This not only improves the overall robustness and sealing of the connector 1 and the connecting tube 2, preventing loosening or leakage during hydraulic operation, but also facilitates disassembly and maintenance.

[0021] Reference Figure 2The outer side of the connecting pipe 2 is provided with three sets of fixing strips 6, and the rear end of the mounting ring 4 is provided with three sets of matching movable grooves 7. Specifically, by cooperating with the fixing strip 6 on the outside of the connecting pipe 2 and the movable groove 7 inside the mounting ring 4, the mounting ring 4 can be easily moved on the outside of the connecting pipe 2, thereby fixing the angle of the mounting ring 4 on the outside of the connecting pipe 2.

[0022] Reference Figure 3 The front end of the connecting pipe 2 is provided with a limiting ring 8, and the rear end of the mounting ring 4 is provided with a matching slot. Specifically, after the mounting ring 4 is moved to the appropriate position, the position of the mounting ring 4 can be fixed by the cooperation of the limiting ring 8 of the connecting pipe 2 and the groove in the mounting ring 4, so as to prevent the mounting ring 4 from moving at will and causing the fixing effect to be lost.

[0023] Reference Figure 2 A limit ring 9 is provided between the connecting pipe 2 and the fixed pipe 3; Specifically, the limiting ring 9 can prevent the mounting ring 4 from detaching from the outside of the connecting pipe 2.

[0024] Reference Figure 3 A sealing ring 10 is provided at the rear end of connector 1; Specifically, the sealing ring 10 can form a reliable seal between the connector 1 and the connecting pipe 2, effectively preventing hydraulic oil leakage. At the same time, it can buffer the minor vibrations caused by pressure fluctuations, improve the safety and durability of the joint, and ensure that the oil circuit pressure is maintained in the high-pressure hydraulic system, thereby improving the overall working efficiency and reliability.

[0025] Example 2: Refer to Figure 5 The fixing structure 5 includes a plug rod 503, which is movably inserted into the upper front end of the mounting ring 4, and a matching slot 504 is provided at the upper rear end of the connector 1. An adjusting plate 505 is installed on the upper end of the plug rod 503, and a return spring 506 is sleeved on the outside of the adjusting plate 505. The two ends of the return spring 506 are respectively connected to the mounting ring 4 and the adjusting plate 505. Specifically, after the mounting ring 4 is moved to the outside of the connector 1, the return spring 506 can drive the insertion rod 503 to insert into the slot 504 opened in the connector 1, which can fix the position of the mounting ring 4 and prevent the mounting ring 4, the connecting tube 2 or the fixing tube 3 from rotating. When it is necessary to remove it, the insertion rod 503 can be disengaged from the slot 504 by pulling the adjusting piece 505, thereby releasing the fixation of the mounting ring 4.

[0026] Working principle: The mounting ring 4 at the front end of the connecting pipe 2 is installed inside the connector 1 through a threaded structure. The connecting pipe 2 is then fixed by the threaded structure. The mounting ring 4 is moved to the outside of the connector 1 by the cooperation of the fixing strip 6 and the movable groove 7. The connector 1 is then fixed by the fixing structure 5. This prevents the connecting pipe 2 and the fixing pipe 3 from rotating and moving, thus preventing gaps between the connecting pipe 2 and the connector 1. The sealing ring 10 formed by the setting can form a reliable seal between the connector 1 and the connecting pipe 2, effectively preventing hydraulic oil leakage.

[0027] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
