[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-5, the present utility model provides a new technical solution: a joint of a metal hose, including a first joint 1, a second joint 2 adapted to the first joint 1 is arranged on the first joint 1, sealing members are arranged on the outer surfaces of two adjacent sides of the first joint 1 and the second joint 2, and the sealing members play a sealing role. A sealing groove 7 is opened on the outer surface of the first joint 1 close to the second joint 2, a fixing ring 8 is fixedly connected to the outer surface of the second joint 2 close to the first joint 1, a rubber ring 9 is arranged on the outer surface of the fixing ring 8 close to the first joint 1, and the rubber ring 9 plays a sealing role. The rubber ring 9 is slidably connected to the fixing ring 8. Metal hoses 3 are arranged on both the first joint 1 and the second joint 2. Two positioning grooves 4 extending out of the right side surface are opened on the left side surface of the second joint 2. Two sliding rods 5 are fixedly connected to the outer surface of the first joint 1 close to the second joint 2, and the sliding rods 5 are slidably connected to the positioning grooves 4. A support block 11 is fixedly connected to the outer surface of the second joint 2 away from the first joint 1. A bidirectional threaded rod 12 penetrating through the lower surface thereof is rotatably connected to the upper surface of the support block 11. Two positioning blocks 10 are threadedly sleeved on the outer surface of the bidirectional threaded rod 12. The two positioning blocks 10 are located at different threads of the bidirectional threaded rod 12. Two straight rods 13 are fixedly connected to both the upper and lower side surfaces of the support block 11. The opposite ends of the two straight rods 13 slidably penetrate through the opposite outer surfaces of the two positioning blocks 10. Sliding grooves 6 adapted to the positioning blocks 10 are opened on the opposite outer surfaces of the two sliding rods 5. The two positioning blocks 10 are slidably connected to the two sliding grooves 6. A worm gear 14 is fixedly sleeved on the outer surface of the bidirectional threaded rod 12. A support rod 15 is rotatably connected to the outer surface of the second joint 2 away from the first joint 1. A worm 17 is fixedly connected to one end of the support rod 15 away from the second joint 2. The worm 17 is meshed with the worm gear 14. A handle 16 is fixedly connected to the end of the worm 17 away from the support rod 15. The outer surfaces of the two positioning blocks 10 away from the first joint 1 are inclined surfaces, and the two positioning blocks 10 are arranged in a mirror image.

[0026] Further, in the initial state, the positioning block 10 does not contact the sliding groove 6. When the first joint 1 and the second joint 2 are butted and contacted, and the two sliding rods 5 slide through the positioning groove 4 and penetrate out of the left side surface of the second joint 2, at this time, the handle 16 is rotated. The rotation of the handle 16 drives the worm 17 and the support rod 15 to rotate. The rotation of the worm 17 drives the worm gear 14 to rotate. The rotation of the worm gear 14 drives the bidirectional threaded rod 12 to rotate, and then synchronously drives the two positioning blocks 10 to move relatively or away from each other. During the displacement process, the two positioning blocks 10 are displaced into the sliding groove 6. The two positioning blocks 10 are displaced into the sliding groove 6 to fix the sliding rods 5, so that the two sliding rods 5 cannot be pulled out of the positioning groove 4, and then the first joint 1 and the second joint 2 are fixed, so that the first joint 1 and the second joint 2 can be butted and fixed, and then the two metal hoses 3 can be connected. The fixed butt joint is convenient and fast, can be installed manually with energy saving and labor saving, and at the same time can improve the butt joint efficiency of the metal hose 3.

[0027] Furthermore, when the first connector 1 is docked with the second connector 2, the fixing ring 8 and the rubber ring 9 also slide into the sealing groove 7 synchronously, thereby increasing the contact area between the first connector 1 and the second connector 2, improving the sealing effect, and making the connection between the two metal hoses 3 more sealed and reliable, and increasing the sealing performance of the connector.

[0028] Furthermore, in this solution, the outer surfaces of the two positioning blocks 10 away from the first connector 1 are set as inclined surfaces, so that when the positioning blocks 10 slide into the sliding groove 6, the inclined surfaces of the positioning blocks 10 contact the left inner wall of the sliding groove 6 first. During the relative displacement of the two positioning blocks 10, the inclined surfaces of the positioning blocks 10 are slidably connected to the left inner wall of the sliding groove 6, thereby squeezing the sliding rod 5 to displace leftward. During the displacement process, the first connector 1 is driven to tightly press the second connector 2, making the seal between the first connector 1 and the second connector 2 more tight and reliable, improving the stability and sealing performance of the metal hose 3 for transmitting the medium, and increasing the sealing performance of the connector.

[0029] Furthermore, in this solution, the connection between the support block 11 and the bidirectional threaded rod 12, and between the support rod 15 and the outer surface of the second connector 2 away from the first connector 1 mainly relies on bearing connection, so that the support rod 15 and the bidirectional threaded rod 12 only rotate and do not displace up and down, left and right, or front and back, increasing the stability of the connector.

[0030] Working principle: When the device is in use, in the initial state, the positioning block 10 does not contact the sliding groove 6. When the first connector 1 is docked with the second connector 2 and the two sliding rods 5 slide through the left side surface of the second connector 2 through the positioning groove 4, at this time, the handle 16 is rotated. The rotation of the handle 16 drives the worm 17 and the support rod 15 to rotate. The rotation of the worm 17 drives the worm gear 14 to rotate. The rotation of the worm gear 14 drives the bidirectional threaded rod 12 to rotate, thereby synchronously driving the two positioning blocks 10 to perform relative or opposite displacements. During the displacement process, the two positioning blocks 10 are displaced into the sliding groove 6. The two positioning blocks 10 are displaced into the sliding groove 6 to fix the sliding rod 5, so that the two sliding rods 5 cannot be pulled out from the positioning groove 4, thereby fixing the first connector 1 and the second connector 2, enabling the first connector 1 and the second connector 2 to be docked and fixed, enabling the two metal hoses 3 to be connected, the fixed docking is convenient and fast, energy-saving and labor-saving for manual installation, saving manpower, and at the same time improving the docking efficiency of the metal hose 3.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
