Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model is provided: a flexible metal-coated hose, including a round tube 1, with metal rings 2 fixedly connected to the left and right ends of the outer wall of the round tube 1, and an installation mechanism 3 provided on the side of the outer wall of the metal rings 2 that is away from each other. The installation mechanism 3 is used to protect the bent hose, and an interface mechanism 4 is provided on the left and right ends of the installation mechanism 3. The interface mechanism 4 is used for connecting the pipe.

[0034] The mounting mechanism 3 includes two fixing rings 301. The fixing rings 301 are engaged in the mortise 304 by mounting tenons 303 and fixed to the outer wall of the metal ring 2. The inner walls of the two fixing rings 301 are respectively set on the opposite side of the outer walls of the two metal rings 2. A metal cover 302 is provided between the adjacent two fixing rings 301. The two ends of the metal cover 302 are fixed with slots 3052. First, the metal cover 302 is inserted into the outer wall of the round tube 1, and the fixing rings 301 are installed. When they are engaged, the buckles 3051 of the fixing rings 301 are engaged in the slots 3052 to achieve fixation. Multiple mounting tenons 303 are fixedly connected on the opposite side of the outer walls of the two metal rings 2. Multiple mortise 304 are provided between the adjacent inner walls of the two fixing rings 301.

[0035] Locking components 305 are provided between adjacent outer walls of the two fixing rings 301. Each locking component 305 includes multiple latches 3051, which are fixedly connected to adjacent outer walls of the two fixing rings 301. Multiple slots 3052 are fixedly connected to the outer walls of the metal cladding 302 on opposite sides. A protective component 306 is provided on the outer wall of the circular tube 1. The protective component 306 includes a moisture-proof layer 3061, which adheres to the outer wall of the circular tube 1 to prevent moisture from entering. When pipe 1 gets damp, the inner wall of the moisture-proof layer 3061 is fixedly connected to the outer wall of the pipe 1. The left and right ends of the moisture-proof layer 3061 are respectively fixedly connected between the two adjacent metal rings 2. The protective component 306 also includes a braided mesh 3062, which holds the pipe 1 and the moisture-proof layer 3061 and provides additional toughness when bent. The inner wall of the braided mesh 3062 is fixedly connected to the outer wall of the moisture-proof layer 3061, and the left and right ends of the braided mesh 3062 are respectively fixedly connected between the two adjacent metal rings 2.

[0036] Specifically, the retaining ring 301 is engaged in the mortise 304 via the mounting tenon 303, achieving a stable connection with the metal ring 2 and ensuring accurate installation. The two ends of the metal cover 302 engage with the buckle 3051 via the slot 3052, achieving a connection and fixation with the retaining ring 301, enhancing the overall structural integrity. The engagement of the mounting tenon 303 and the mortise 304 provides reliable installation positioning for the retaining ring 301, preventing it from loosening during use. The mortise 304 and the mounting tenon 303 are compatible, ensuring the retaining ring 301... It can be precisely installed on the metal ring 2. The buckle 3051 engages in the slot 3052, which tightly fixes the metal cover 302 to the fixing ring 301, preventing the metal cover 302 from shifting. The slot 3052 provides a snap-fit ​​position for the buckle 3051, ensuring that the buckle 3051 can be stably snapped in. The moisture-proof layer 3061 adheres to the outer wall of the round tube 1, blocking the intrusion of external moisture and protecting the round tube 1 from moisture damage. The woven mesh 3062 holds the round tube 1 and the moisture-proof layer 3061, improving the bending resistance of the overall structure and making the round tube 1 more durable when bent.

[0037] Reference Figure 1 , Figure 3 and Figure 4The interface mechanism 4 includes two threaded posts 401. The threaded posts 401 are screwed into the threaded grooves 402 on the inner wall of the fixing ring 301 by rotation. The outer walls of the two threaded posts 401 are threadedly connected to the opposite sides of the inner walls of the two fixing rings 301. Each opposite side of the inner wall of the two fixing rings 301 has a threaded groove 402. Each opposite side of the two threaded posts 401 is fixedly connected to a fixing seat 403. Both the fixing seat 403 and the threaded posts 401 are hollow tubular. Each of the two opposite sides of 403 is fixedly connected to a connector 404. The outer wall of the connector 404 is hexagonal. The interface mechanism 4 also includes two sealing rings 405. The opposite sides of the two sealing rings 405 are fixedly connected between the adjacent two fixed seats 403. The inner walls of the two sealing rings 405 have raised ring structures. When the threaded post 401 and the fixed ring 301 are connected in place, the sealing ring 405 is pressed between the fixed seat 403 and the fixed ring 301 to achieve a sealing effect at the connection.

[0038] A connecting component 406 is provided on the inner side of the connector 404. The connecting component 406 includes multiple anti-loosening rings 4061. The outer walls of the multiple anti-loosening rings 4061 are respectively fixedly connected to the inner walls of the two connectors 404 on opposite sides. Limiting rings 4062 are fixedly connected between adjacent inner walls of the two connectors 404. When an external pipe is inserted into the device, the limiting rings 4062 prevent the pipe from being inserted too deeply, and the anti-loosening rings 4061 increase the friction with the pipe to prevent them from falling off. The connecting component 406 also includes two dust covers 4063. The dust covers 4063 are plugged into the opening of the connector 404 during device transportation and restriction to prevent dust and debris from entering. The outer walls of the two dust covers 4063 are respectively located on opposite sides of the two connectors 404. There are protruding cylindrical structures between adjacent dust covers 4063 to facilitate insertion into the opening of the connector 404.

[0039] Specifically, the threaded post 401 is screwed into the threaded groove 402 on the inner wall of the fixing ring 301 by rotation, so as to achieve a detachable connection with the fixing ring 301, which is convenient for installation and disassembly. The threaded groove 402 is adapted to the threaded post 401 to ensure a stable connection after the threaded post 401 is screwed in. The fixing seat 403 and the threaded post 401 are hollow tubes to provide a channel for the flow of media. The outer wall of the connector 404 is hexagonal, which is convenient for rotation and fixing with tools. When the threaded post 401 and the fixing ring 301 are connected in place, the sealing ring 405 is pressed between the fixing seat 403 and the fixing ring 301 to prevent the media from leaking from the connection and ensure reliable sealing.

[0040] The anti-loosening ring 4061 increases the friction with the external pipeline to prevent the pipeline from falling off during use and ensures a stable connection. The limit ring 4062 limits the insertion depth when the external pipeline is inserted to avoid the pipeline being inserted too deeply and affecting its use. The dust cover 4063 is plugged into the opening of the connector 404 when the device is transported or idle to prevent dust and debris from entering the interior of the connector 404 and keep the connector 404 clean.

[0041] Working principle: The moisture-proof layer 3061 is attached to the outer wall of the round pipe 1, and the woven mesh 3062 is wrapped around the outside of the moisture-proof layer 3061. The left and right ends of the moisture-proof layer 3061 and the woven mesh 3062 are respectively connected to two metal rings 2. Then, the metal cover 302 is inserted into the outer wall of the round pipe 1, and the two fixing rings 301 are engaged in the mortise 304 on the outer wall of the metal ring 2 by the mounting tenon 303. At this time, the buckle 3051 of the fixing ring 301 is engaged in the slot 3052 of the metal cover 302, thus completing the assembly of the installation mechanism 3.

[0042] Rotate the threaded post 401 of the interface mechanism 4 into the threaded groove 402 on the inner wall of the fixing ring 301, so that the fixing seat 403 drives the connector 404 to connect with the fixing ring 301. When the threaded post 401 and the fixing ring 301 are connected in place, the sealing ring 405 presses between the fixing seat 403 and the fixing ring 301 to achieve a seal. Before use, remove the dust cover 4063 at the opening of the connector 404 and insert the external pipe into the connector 404. The limiting ring 4062 limits the insertion depth of the pipe, and the anti-loosening ring 4061 increases the friction with the pipe to prevent it from falling off. During use, the round pipe 1 can be bent as needed. The braided mesh 3062 improves the bending ability of the round pipe 1. The metal coating 302 protects the bent part of the round pipe 1. The moisture-proof layer 3061 prevents moisture from entering the round pipe 1.

[0043] If disassembly is required, unscrew the threaded post 401 from the threaded groove 402 of the retaining ring 301, separate the interface mechanism 4 from the mounting mechanism 3, then release the engagement between the buckle 3051 and the slot 3052, and remove the metal cover 302, the braided mesh 3062 and the moisture-proof layer 3061.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
