DETAILED DESCRIPTION

[0017] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0018] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , the metal-clad flexible pipe for gas appliance connection comprises a flexible pipe 1 and a joint 2 integrally formed with the flexible pipe 1, the joint 2 is provided at the rear end with a knob 3 arranged around the flexible pipe 1, the knob 3 abuts against the joint 2, and a plurality of buckle parts 4 arranged in a ring are arranged on the abutting surface of the knob 3, the joint 2 is provided with an annular groove 5 for rotation of the buckle parts 4, and a plurality of matching parts 6 matched with the buckle parts 4 are arranged in the annular groove 5.

[0019] A limiting groove 7 is arranged on the inner wall of the knob 3, and a limiting part 8 limiting the limiting groove 7 is arranged on the flexible pipe 1, and an elastic element 9 with elastic return function is arranged between the limiting part 8 and the limiting groove 7.

[0020] A linkage rod 10 is arranged on one side of the knob 3 and extends into the joint 2, a channel 14 is arranged on the annular groove 5 for the linkage rod 10 to pass through, a spiral piece 11 spirally arranged around the joint 2 is arranged on the inner wall of the joint 2, one end of the spiral piece 11 is connected with the linkage rod 10, and the spiral piece 11 has elastic return function.

[0021] In use, the connector 2 is connected with a gas stove or the like, the knob 3 is continuously screwed to rotate the linkage rod 10, the linkage rod 10 rotates one end of the helical piece 11 to make the helical piece 11 screw, thereby extruding the inner wall of the connector 2 to make the connector 2 connect with the gas stove or the like closely, and after completion, the knob 3 is loosened, and the knob 3 is reset through the elastic element 9;

[0022] When disassembly is needed, the knob 3 is pulled to make the limiting part 8 abut against the limiting groove 7, thereby making the buckle part 4 loosen from the annular groove 5, and after loosening, the helical piece 11 is elastically reset due to the loosening of the buckle part 4 from the annular groove 5, thereby loosening the connection with the gas stove.
