[0026] like Figures 1-6 As shown in the figure, the hydraulic fitting anti-detachment structure provided in this embodiment includes an intermediate pipe 1, with hydraulic pipes 2 installed at both ends of the intermediate pipe 1. Connecting shells 3 are fixedly connected to both ends of the intermediate pipe 1, and a connecting cylinder 4 is fixedly connected to one end of each hydraulic pipe 2. The connecting cylinder 4 can be rotatably engaged with the inner side of the connecting shell 3. A sealing gasket 5 is provided between the connecting shell 3 and the connecting cylinder 4. The connecting shell 3 and the connecting cylinder 4 are interconnected by multiple bolts 6. Through the arrangement of the intermediate pipe 1, connecting shell 3, and connecting cylinder 4, the connecting cylinder 4 can be rotatably engaged with the inner side of the connecting shell 3, and locked in place by the bolts 6, preventing loosening and detachment due to excessive force.

[0027] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, a baffle 7 is fixedly connected to the end of the connecting shell 3 away from the intermediate tube 1. Multiple mounting slots 8 are provided on the baffle 7. Multiple locking plates 9 that mate with the mounting slots 8 are fixedly connected to the end of the connecting cylinder 4 near the connecting shell 3. A connecting groove is provided on the side of the locking plate 9 near the connecting shell 3. A spring 10 is fixedly connected to the inner side of the connecting groove. A top sleeve 11 is connected to one end of the spring 10. A through hole 12 that mates with the top sleeve 11 is provided on the outer wall of the connecting shell 3. With the baffle 7, mounting slots 8, and locking plates 9, during connection, the locking plate 9 is aligned with the mounting slot 8 and then pushed into the connecting shell 3. The connecting cylinder 4 is rotated to lock it in place. Through the arrangement of the spring 10, top sleeve 11, and through hole 12, when the connecting cylinder 4 is rotated, the top sleeve 11 is locked into the through hole 12 under the action of the spring 10, further preventing loosening and detachment.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a first connecting plate 13 is fixedly connected to the outer wall of the connecting cylinder 4, and a second connecting plate 14 is fixedly connected to the outer wall of the connecting shell 3.

Wear-resistant layers are provided on the side walls where the clamping plate 9 and the baffle 7 connect. The wear-resistant layers improve service life. The seamless steel pipe 1 and the stainless steel connecting shell 3 and the connecting cylinder 4 can withstand greater pressure. The nitrile rubber sealing ring 5 has good elasticity and sealing performance and is suitable for a wide temperature range.

[0029] In this embodiment, as Figures 1-6 As shown in the figure, the working principle of the hydraulic fitting anti-detachment structure provided in this embodiment is as follows:
