[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 5 As shown, in this embodiment, a corrosion-resistant metal hose connector includes a hose body 1. The number of hose bodies 1 is two. The two hose bodies 1 are connected by a connector mechanism. The connector mechanism consists of a No. 1 connector 2, a No. 2 connector 3 and a connecting column 5. The No. 1 connector 2 is rotatably connected to one hose body 1 through a rotating seat 4, and the No. 2 connector 3 is fixedly connected to the other hose body 1. A connecting groove 6 is provided at the end of the No. 1 connector 2, and a connecting column 5 threadedly matched with the connecting groove 6 is fixedly connected to the end of the No. 2 connector 3. The axis of the connecting column 5 is hollowed out, and the No. 1 connector is rotatably connected to the one hose body 1 through a rotating seat 4. The No. 2 connector 3 is fixedly connected to the other hose body 1. An anti-retreat mechanism is arranged between joint 2 and joint No. 2 3, and the anti-retreat mechanism consists of an anti-retreat rod 14 and a movable plate 13. A movable groove 10 is provided inside joint No. 2 3, and the movable groove 10 is an annular structure. The movable plate 13 is slidably connected to the movable groove 10. A plurality of through holes 11 extending to the outside of joint No. 2 3 are provided on the inner wall of the movable groove 10, and anti-retreat rods 14 are slidably installed in the plurality of through holes 11, respectively. The plurality of anti-retreat rods 14 are fixedly connected to one end of the movable plate 13, and the other end of the movable plate 13 is connected to a driving mechanism. A plurality of anti-retreat holes 7 are provided at the end of joint No. 1 2.

[0022] Among them, the plurality of anti-retreat rods 14 are distributed in a ring array, the plurality of anti-retreat holes 7 correspond to the plurality of anti-retreat rods 14 one by one, and the anti-retreat holes 7 are slidably fitted with the anti-retreat rods 14 .

[0023] The cooperation between the anti-backward rod 14 and the anti-backward hole 7 can prevent the threaded connection between the No. 1 connector 2 and the No. 2 connector 3 from loosening.

[0024] Among them, the driving mechanism is composed of a connecting plate 15, a driving plate 16 and a spring 17. The connecting plate 15 is fixedly connected to the movable plate 13. One end of the connecting plate 15 slides through the No. 2 joint 3 and extends to the outside of the No. 2 joint 3. The No. 2 joint 3 is provided with a through groove 12 that slides with the connecting plate 15. The protruding end of the connecting plate 15 is fixedly connected to the driving plate 16. A plurality of springs 17 are arranged on the outer surface of the connecting plate 15. One end of the spring 17 is fixedly connected to the movable plate 13, and the other end of the spring 17 is fixedly connected to the inner wall of the movable groove 10.

[0025] By pulling the driving plate 16 , the movable plate 13 can be controlled to move in the movable groove 10 , thereby controlling whether the anti-retraction rod 14 extends out of the through hole 11 .

[0026] A plurality of springs 17 are distributed on the outer surface of the connecting plate 15 in a ring-shaped array.

[0027] Such an arrangement can make the forces exerted by the multiple springs 17 on the movable plate 13 more balanced.

[0028] The end of the connecting column 5 is fixedly connected with a sealing plate 9 , which is an annular plate. The bottom of the inner cavity of the connecting groove 6 is provided with a sealing groove 8 , which is matched with the sealing plate 9 .

[0029] When the No. 1 joint 2 and the No. 2 joint 3 are connected, the sealing plate 9 will be just inserted into the sealing groove 8, thereby further improving the sealing performance of the connection between the No. 1 joint 2 and the No. 2 joint 3.

[0030] Wherein, the No. 1 connector 2 and the No. 2 connector 3 are both made of copper, which has good corrosion resistance and can effectively ensure the service life of the connector.

[0031] The utility model provides a corrosion-resistant metal hose connector, and the specific working principle is as follows:

[0032] When in use, pull the driving plate 16 in the direction away from the No. 1 connector 2, drive the movable plate 13 to move in the movable groove 10, and retract the anti-retraction rod 14 into the through hole 11. At this time, the movable plate 13 will compress the spring 17, and then the No. 1 connector 2 and the No. 2 connector 3 are connected through the threaded cooperation of the connecting column 5 and the connecting groove 6. When the No. 1 connector 2 and the No. 2 connector 3 are connected, the multiple through holes 11 on the No. 2 connector 3 will just be aligned with the multiple anti-retraction holes 7 on the No. 1 connector 2. At this time, release the driving plate 16, and under the action of the spring 17 restoring the deformation, the multiple anti-retraction rods 14 will be inserted into the multiple anti-retraction holes 7. Under the action of the anti-retraction rod 14, there will be no relative rotation between the No. 1 connector 2 and the No. 2 connector 3, thereby avoiding the loosening of the threaded connection between the No. 1 connector 2 and the No. 2 connector 3.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
