A limiting ring 130 is fixedly provided on the circumferential outer wall of the second heat-insulating pipe 110. Limiting blocks 140 are symmetrically and fixedly provided on the inner wall of the fixing sleeve 120. The limiting blocks 140 cooperate with the limiting ring 130 to limit the second heat-insulating pipe 110. A fixing ring 150 that cooperates with the fixing sleeve 120 is fixedly provided on the circumferential outer wall of the second heat-insulating pipe 110 for fixing the first heat-insulating pipe 100 and the second heat-insulating pipe 110. Snap rods 160 that cooperate with the fixing ring 150 are symmetrically and slidably connected to the circumferential outer wall of the fixing sleeve 120 for fixing the fixing ring 150. By inserting the fixing ring 150 into the fixing opening provided on the side wall of the fixing sleeve 120, it is limited by the limiting blocks 140. The spring pushes the limiting ring 161, causing the snap rod 160 to move downward so that it is embedded in the snap opening provided at the top of the fixing ring 150, and the fixing ring 150 can be fixed, thereby quickly installing the second heat-insulating pipe 110. Then, by pulling the snap rod 160 outward and removing the second heat-insulating pipe 110, the second heat-insulating pipe 110 can be quickly disassembled, facilitating the replacement and repair of the heat-insulating pipe;

[0026] The first heat-insulating pipe 100 includes an inner pipe 200. A heat-insulating layer 210 is fixedly provided on the circumferential outer wall of the inner pipe 200. The material of the heat-insulating layer 210 is glass wool for heat-insulating the inner pipe 200.

The material of the wear-resistant layer 280 is wear-resistant polyethylene for increasing the wear resistance of the heat-insulating pipe. When the heat-insulating pipe is impacted externally, the reinforcing rod 231 is stressed and squeezes the buffer opening provided at the top of the buffer seat 230 to absorb the pressure applied by the reinforcing rod 231, thereby buffering the inner pipe 200. At the same time, when the reinforcing plate 240 is stressed and moves downward, it drives a plurality of buffer blocks 260 to move downward, thereby driving the connecting plate 261 to move downward. Then, it is buffered by a plurality of arc-shaped rubber blocks 270. Cooperating with the buffer seat 230, the buffering effect on the inner pipe 200 can be better.

[0029] It should be noted that a limiting ring 161 is fixedly arranged on the circumferential outer wall of the buckle rod 160, which is used to limit the buckle rod 160. A spring that cooperates with the limiting ring 161 is sleeved on the circumferential outer wall of the buckle rod 160, which is used to push the limiting ring 161 and drive the buckle rod 160 to move downward.

[0030] It should be noted that a connecting plate 261 is fixedly arranged at the bottom of multiple buffer blocks 260, making the force on the rubber block 270 more uniform. Multiple rubber blocks 270 that cooperate with the connecting plate 261 are fixedly arranged inside the support seat 250, which are used to buffer the connecting plate 261. The rubber blocks 270 are arc-shaped, which can make the buffering effect of the rubber blocks 270 better.

[0031] Working principle: First, insert the fixing ring 150 into the fixing port provided on the side wall of the fixing sleeve 120, and limit it by the limiting block 140. The spring pushes the limiting ring 161, making the buckle rod 160 move downward, so that it is embedded in the bayonet provided at the top of the fixing ring 150, and the fixing ring 150 can be fixed, thereby quickly installing the heat preservation pipe 110. Then, by pulling the buckle rod 160 outward and removing the heat preservation pipe 110, the heat preservation pipe 110 can be quickly disassembled, which is convenient for replacing and repairing the heat preservation pipe. When the heat preservation pipe is impacted externally, the reinforcing rod 231 is stressed and squeezes the buffer port provided at the top of the buffer seat 230, which is used to absorb the pressure applied by the reinforcing rod 231, thereby buffering the inner pipe 200. At the same time, when the reinforcing plate 240 is stressed and moves downward, it drives multiple buffer blocks 260 to move downward, thereby driving the connecting plate 261 to move downward. Then, multiple arc-shaped rubber blocks 270 are used for buffering, and cooperating with the buffer seat 230, the buffering effect on the inner pipe 200 can be better.
