DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings:

[0013] See attached Figure 1 :In this embodiment 1, a crimping oil pipe joint includes a joint body 1, which is the basic part of the crimping oil pipe joint and is used to connect the pipeline of the entire system. The lower end of the joint body 1 is provided with a pipe thread joint 2, which is connected to the pipeline by a threaded connection method to ensure the fixation of the pipeline and the transmission of the fluid. And the right end of the joint body 1 is provided with a connecting section 3 as an intermediary for connecting the hose 5 and other components.

[0014] The right end of the connecting section 3 is provided with a plug-in section 4, which is connected to a hose 5. The plug-in section 4 is used to directly insert the hose 5 to form an extension of the pipeline. The hose 5 is connected to the plug-in section 4 and is an important part of the oil pipe system for conveying oil. A sleeve tube 6 is provided on the outside of the hose 5, which is used to provide additional protection and support. A crimping section 7 is provided on the sleeve tube 6, which is used to tighten by a crimping machine to ensure a firm connection between the sleeve tube and the hose.

[0015] The connecting section 3 is provided with a mounting slot 8, and a buckle plate 9 is fixedly connected to the mounting slot 8 by a buckle. Elastic hooks 10 are provided at the upper and lower ends of the buckle plate 9, and the mounting slot 8 is used to install and fix the buckle plate 9. A limiting flange 11 is provided at one end of the sleeve tube 6, and an elastic gasket 12 is provided on the end surface of the limiting flange 11. The elastic gasket 12 provides a buffering and sealing effect to enhance the stability of the connection. The limiting flange 11 is fixedly connected with the elastic hook 10 by a buckle. The elastic hook 10 provides a fixing force to adapt to sleeve tubes of different sizes. The limiting flange 11 is used to position and limit the hose 5 to prevent it from falling off under high pressure.

[0016] The working principle of the above-mentioned crimping oil pipe joint scheme is as follows: the pipe threaded joint 2 at the lower end of the joint body 1 is connected to the pipeline, and at the same time, the connecting section 3 set at the right end of the joint body 1 is connected to the hose 5 through the plug-in section 4. The sleeve tube 6 on the outside of the hose is fastened to the hose through the crimping section 7 to ensure the stability of the connection. The mounting groove 8 on the connecting section 3 is used to fix the buckle plate 9, and the elastic hook 10 on the buckle plate 9 cooperates with the limiting flange 11 at the end of the sleeve tube 6, and provides additional sealing and buffering through the elastic gasket 12. When the hose needs to be replaced, the sleeve tube 6 can be quickly removed by removing the buckle plate 9 and releasing the fixation of the elastic hook 10, thereby realizing the rapid replacement of the hose 5. Such a design improves maintenance efficiency and reduces operational complexity.

[0017] As attached Figure 2 As shown, in Example 2, on the basis of Example 1, an adjusting screw 13 is provided on the gusset plate 9, an adjusting nut 14 is threadedly connected to the adjusting screw 13, and a spring 18 is provided between the adjusting nut 14 and the elastic hook 10. The adjusting screw 13 added to the gusset plate 9 and the adjusting nut 14 threadedly connected thereto provide a fine-tuning mechanism for applying force to the elastic hook 10. By rotating the adjusting nut 14, the position of the adjusting nut 14 on the adjusting screw 13 can be adjusted, thereby changing the preload force of the spring 18, which allows the operator to accurately adjust the clamping force of the elastic hook 10 according to the size of the hose 5 and the buckling requirements, ensuring that the connection between the sleeve tube 6 and the hook is firm, thereby preventing the sleeve tube 6 from falling off.

[0018] The other end of the sleeve tube 6 is sleeved with an elastic rubber hoop 15. The elastic rubber hoop 15 plays a role in strengthening the fixation. When the sleeve tube 6 is buckled on the rubber tube 5, the elastic rubber hoop 15 has a tendency to shrink, providing additional fastening force for the outer end of the sleeve tube 6, thereby enhancing the stability and durability of the entire joint system.

[0019] The buckle plate 9 is provided with a U-shaped slot 16 that cooperates with the mounting slot 8, providing a structure for quick installation and removal. The design of the U-shaped slot 16 allows the buckle plate 9 to be more easily inserted into and removed from the mounting slot 8. The U-shaped slot 16 is provided with a magnet 17, and the addition of the magnet 17 increases the adsorption force between the buckle plate 9 and the mounting slot 8, ensuring that the buckle plate 9 can be more firmly fixed when it is installed in place, preventing the buckle plate 9 from accidentally falling off under high pressure or vibration environments, thereby improving the safety and reliability of the joint.

[0020] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
