[0002] The hose connector is a high-quality flexible pipe in modern industrial pipelines. It is similar to the cable connector in functionality and needs to achieve a sealing and fixing effect. In some specific occasions, it is necessary to use a hose connector for steering connection. Right-angle hose connectors are often used. The structure of a traditional right-angle hose connector basically includes a connector body, a tightening nut and a tightening cap.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-4 , a hose right angle joint, comprising: a joint body 4, both ends of the outer side of the joint body 4 are provided with locking mechanisms;
[0024] The locking mechanism includes a fixing ring 5, a clamping ring 2, a tightening cover 1, a threaded barrel 3 and a positioning ring 6. The fixing ring 5 is fixedly sleeved on the outside of the joint body 4, and the clamping ring 2 and the threaded barrel 3 are fixedly installed on one side of the fixing ring 5. The tightening cover 1 is threadedly sleeved on the outside of the threaded barrel 3, and the tightening cover 1 is provided with a plurality of positioning grooves 12. A plurality of positioning rods 11 are fixedly connected to one side of the positioning ring 6, and the plurality of positioning rods 11 are movably inserted into the corresponding positioning grooves 12 respectively.
[0025] In this embodiment, a connecting rod 8 is fixedly connected to one side of the positioning ring 6, and one end of the connecting rod 8 is fixedly connected to a connecting disk 10. A circular groove is provided on the other side of the fixing ring 5, and the connecting disk 10 is slidably connected in the corresponding circular groove, thereby guiding the movement of the positioning ring 6. A compression spring 9 is fixedly connected to one side of the connecting disk 10, and a fixing disk 7 is fixedly installed in the circular groove. The other end of the compression spring 9 is fixedly connected to one side of the corresponding fixing disk 7, thereby resetting the connecting disk 10. A sliding hole is provided on one side of the fixing disk 7, and the connecting rod 8 is slidably connected in the corresponding sliding hole, and the connecting rod 8 is guided by the sliding hole.
[0026] In this embodiment, a plurality of clamping protrusions are integrally formed on one side of the clamping ring 2, a chamfer is provided on the outer side of the clamping protrusion, and an annular inclined protrusion adapted to the chamfer is provided on the inner wall of the screw-on cover 1. When the annular inclined protrusion moves and abuts against the clamping protrusion, the clamping protrusion can bend inward and abut against the outer side of the hose, thereby fixing the hose through the relative friction between the hose and the hose to prevent the hose from falling off.
[0027] In this embodiment, a plurality of grooves 13 are formed on the outer side of the screw-on cover 1 , so as to facilitate manual rotation of the screw-on cover 1 .
[0028] In this embodiment, a plurality of transverse holes are opened on one side of the fixing ring 5 , and a plurality of positioning rods 11 are respectively slidably connected in the corresponding transverse holes to further guide the positioning rods 11 .

Then, the tightening cover 1 is rotated. The tightening cover 1 rotates and moves along the axis of the threaded barrel 3 by cooperating with the thread of the threaded barrel 3. During the movement, the annular inclined protrusion on the inner side of the tightening cover 1 abuts against the compression protrusion, and the compression protrusion is pushed to the joint body 4 to be compressed, thereby compressing and fixing the hose. By loosening the locating ring 6, the compression spring 9 drives the connecting plate 10 to move in the opposite direction under the action of its own elastic force, and drives the locating rod 11 to move in the opposite direction through the connecting rod 8 and the locating ring 6, so that the locating rod 11 is reinserted into the corresponding slot, thereby fixing the tightening cover 1 to prevent it from loosening, thereby preventing the compression protrusion from loosening, thereby avoiding the loosening of the hose, thereby ensuring the sealing of the connection and preventing leakage.
