Description

Technical Field

[0001] This application relates to the technical field of quick connectors, and specifically to a quick connector for a metal hose. Background Art

[0002] Metal hoses are important components in the connecting pipelines of modern industrial equipment. Metal hoses are used as wire and cable protection tubes for wires, cables, and automated instrument signals, as well as civil shower hoses. The specifications range from 3mm to 150mm.

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] Embodiment

[0023] Please refer to Figures 1-4, A quick connector for a metal hose, including a fixed seat 1. One end of the fixed seat 1 is connected and installed with a connecting cylinder 2, and a limiting mechanism is arranged on the outer side wall of the fixed seat 1; A sealing ring 8 is fixedly installed on the outer side wall of the connecting cylinder 2, and the outer side wall of the sealing ring 8 is closely attached to the inner side wall of the metal hose. By installing the sealing ring 8, the sealing effect when the metal hose is attached to the connecting cylinder 2 is improved. A plurality of handles 9 are fixedly installed on the outer side wall of the fixed cylinder 6. By installing the handles 9, it is convenient for the user to perform a rotation operation on the fixed cylinder 6.

[0024] Please refer to Figures 1-4 , The limiting mechanism includes a first fixing ring 3. The inner side wall of the first fixing ring 3 is closely attached to the outer side wall of the connecting cylinder 2. The metal hose is located between the first fixing ring 3 and the connecting cylinder 2. A second fixing ring 4 is fixedly installed on the outer side wall of the first fixing ring 3. A clamping plate 5 is closely attached and clamped on the outer side wall of the first fixing ring 3. A fixed cylinder 6 is fixedly installed on the outer side wall of the clamping plate 5. The inner side wall of the fixed cylinder 6 is screwed with the outer side wall of the fixed seat 1. A plurality of guiding strips 7 are fixedly installed at one end of the outer side wall of the connecting cylinder 2 away from the fixed seat 1. For this quick connector of the metal hose, through the guiding of the guiding strips 7, the metal hose passes through the guiding strips 7 and then is closely attached to the outer side wall of the connecting cylinder 2. By the guiding strips 7 on the first fixing ring 3 contacting the outer side wall of the hose, the metal hose is preliminarily limited. By rotating the fixed cylinder 6, the clamping plate 5 is closely attached to the outer side wall of the first fixing ring 3, thus completing the quick installation and fixing operation of the metal hose, improving the convenience and connection efficiency during the connection operation of the metal hose, facilitating the quick installation and disassembly operation of the metal hose, and improving the practicability.

[0025] Please refer to Figure 2 , It should also be noted that a limiting pad 10 is fixedly installed between the first fixing ring 3 and the fixed seat 1. By installing the limiting pad 10, the sealing effect between the first fixing ring 3 and the fixed seat 1 is improved.

[0026] Anti-slip coatings are applied on the outer side walls of each handle 9. By applying the anti-slip coatings, the convenience of the user when using the handle 9 is improved.

[0027] Please refer to Figure 2 , A plurality of anti-slip strips 11 are fixedly installed on the inner side wall of the second fixing ring 4. By installing the anti-slip strips 11, the stability effect when the second fixing ring 4 contacts the outer side wall of the metal hose is improved.

[0028] In summary, when the quick connector of the metal hose is in use and the metal hose needs to be installed, the first fixing ring 3 is sleeved on one end of the metal hose. One end of the metal hose passes through the guiding strip 7 and is closely attached to the outer wall of the connecting cylinder 2. It passes through the sealing ring 8 installed on the connecting cylinder 2, and then the sealing ring 8 performs preliminary fixing and sealing operations on the metal hose. The first fixing ring 3 is sleeved on one end of the metal hose located on the outer wall of the connecting cylinder 2. The anti-slip strip 11 installed inside the guiding strip 7 is closely attached to the metal hose, and then the re-fixing operation of the metal hose is completed. By rotating the handle 9, the fixing cylinder 6 is synchronously driven to rotate on the outer wall of the fixing seat 1. While the fixing cylinder 6 rotates, the clamping plate 5 is synchronously driven to clamp the outer wall of the first fixing ring 3. Then, through the close attachment of the first fixing ring 3 to the outer walls of the metal hose and the connecting cylinder 2, the fixing operation of the metal hose can be completed.

[0029] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
