[0007] The utility model is further configured as follows: the isolation sheet is configured as a double-layer partition plate, and a plurality of gaps are formed between the double-layer partition plates, and the isolation sheet is configured as an arc shape.

[0008] The utility model is further configured as follows: two grooves are opened on the support bar, and the long side edges of the isolation sheet are embedded in the groove area.

[0009] The utility model is further configured as follows: a plurality of pits are arranged on the support bar, a plurality of the pits are arranged to form a row, and a projection that can be embedded in the pits is formed in the groove area of ​​the support bar.

[0010] The utility model is further configured as follows: a cushion strip is bonded and connected to one side of the isolation sheet close to the inner tube.

[0011] The utility model is further configured as follows: a second gasket is bonded and arranged on the side of the support strip that is in contact with the outer tube, and on the side of the cushion strip that is in contact with the inner tube.

[0012] In summary, the utility model has the following beneficial effects: during the installation of the inner tube and the outer tube, the isolation sheet pushes the inner tube and the outer tube, and the position and posture of the isolation sheet are fixed, so that the position of the cavity between the inner tube and the outer tube is maintained, thereby forming a thermal insulation effect for the entire tube.

[0016] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] A thermally insulating metal pipe, such as Figure 1-Figure 2 As shown, it includes an inner tube 1 and an outer tube 2 sleeved outside the inner tube 1, and a plurality of isolation sheets 3 are arranged between the inner tube 1 and the outer tube 2. The isolation sheets 3 arranged between the inner tube 1 and the outer tube 2 are used to form a temperature isolation between the inner tube 1 and the outer tube 2, so that the mutual influence of the temperature between the inner tube 1 and the outer tube 2 can be minimized to the greatest extent, and the effect of heat preservation of the metal pipe is achieved. Each isolation sheet 3 is provided with two layers, and a first gasket 4 is arranged between the two layers of isolation sheets 3. The first gasket 4 is arranged to form a temperature isolation effect between two adjacent isolation sheets 3, so as to form a maximum degree of prevention of temperature conduction. The isolation sheets 3 and the first gasket 4 have an effect on the inner tube 1 and the outer tube 2 form a support, the isolation sheet 3 is set to an arc shape, the isolation sheet 3 is set to use a memory metal material, when the isolation sheet 3 and the outer tube 2 are installed, the isolation sheet 3 is deformed so that the outer tube 2 can be embedded in the inner tube 1, and the isolation sheet 3 and the first gasket 4 are provided with support strips 5 on the long side edges, and the support strips 5 are provided for the adjacent isolation sheets 3 to be fixed at intervals, and the isolation sheet 3 and the support strips 5 can be made into a tubular shape in advance to facilitate installation, the isolation sheet 3 is set as a double-layer partition, and a plurality of gaps 6 are formed between the double-layer partitions, and the gaps 6 are provided for air retention, thereby forming temperature isolation and achieving a thermal insulation effect.

[0018] The support bar 5 is provided with two grooves, and the long edges of the isolation sheet 3 are embedded in the groove area. The grooves are set to fix the position of the isolation sheet 3, so as to form a situation where the isolation sheet 3 and the support bar 5 are misaligned between the inner tube 1 and the outer tube 2 during use. A plurality of pits are provided on the support bar 5, and the plurality of pits are arranged in a row. The groove area of ​​the support bar 5 is formed with a protrusion 8 that can be embedded in the pits. The setting of the pits can be used to fix the position of the isolation sheet 3 when it is embedded in the groove of the support bar 5, so as to facilitate the user to install the support bar 5 and the isolation sheet 3 in advance, and to insert them simultaneously during the process of sleeve-mounting the inner tube 1 and the outer tube 2, and to limit the distance between the inner tube 1 and the outer tube 2. The isolation sheet 3 is bonded with a gasket 9 on one side close to the inner tube 1. The gasket 9 is set to form an isolation between the isolation sheet 3 and the inner tube 1 to avoid wear between the isolation sheet 3 and the inner tube 1 caused by shaking of the isolation sheet 3.

[0019] A second gasket 10 is bonded to one side of the first gasket 4 that is in contact with the outer tube 2, and to one side of the gasket strip 9 that is in contact with the inner tube 1. The second gasket 10 is made of plastic material to form a sheet material with a smooth surface, thereby reducing the friction between the outer tube 2 and the first gasket 4, and between the gasket strip 9 and the second gasket 10, and helping to more quickly embed the support bar 5, the isolation sheet 3 and the gasket strip 9 between the inner tube 1 and the outer tube 2.
