[0004] Most of the existing stainless steel pipes are insulated and protected on the outside through an insulating layer when in use, but there is no insulating mechanism on the inside to insulate the inner wall of the stainless steel pipe. This will cause the stainless steel pipe to leak electricity when it is used later because there is no insulating mechanism on the inner wall, which will cause the stainless steel pipe to be dangerous to use.

[0005] Therefore, we proposed that double-insulated stainless steel pipes can solve the above problems well. Utility Model Content

[0006] The purpose of the utility model is to provide a double-insulated stainless steel pipe to solve the problem raised by the above-mentioned background technology that most of the existing stainless steel pipes on the market are insulated and protected on the outside of the stainless steel pipe during use, but no insulating mechanism is provided on the inside to insulate and protect the inner wall of the stainless steel pipe, which will cause the stainless steel pipe to leak electricity during later use because there is no insulating mechanism on the inner wall, thereby making the stainless steel pipe dangerous to use.

[0007] To achieve the above object, the utility model provides the following technical solutions: a double-insulated stainless steel pipe, comprising a stainless steel pipe body, the surface of which is cylindrical, and a sealing disk is sealed and welded on the outer end of the stainless steel pipe body, and the diameter of the sealing disk is greater than the diameter of the stainless steel pipe body;

[0008] It also includes: a stainless steel pipe body, an outer coating is arranged on the outer side of the stainless steel pipe body, and an inner coating is arranged on the inner side of the stainless steel pipe body, and both the outer coating and the inner coating are made of ceramic coating material.

[0009] Preferably, the outer side of the stainless steel pipe body is coated with an outer insulation layer, and the inner side of the stainless steel pipe body is coated with an inner insulation layer, and both the outer insulation layer and the inner insulation layer are made of polyurethane foam plastic.

[0011] Preferably, the sealing disk has positioning plates disposed at both ends thereof, and the two positioning plates are both semicircular in shape, and the inner sides of the two positioning plates correspond to the stainless steel tube body.

[0012] Preferably, anti-skid pads are fitted on the inner sides of the two positioning plates, and the two anti-skid pads have the same structure, and the inner sides of the two anti-skid pads are fitted and connected to the outer side wall of the stainless steel pipe body.

[0013] Preferably, the sealing disk has grooves at both upper and lower ends thereof through which pressing rods are slidably installed, and the two pressing rods are symmetrically arranged about the transverse center line of the sealing disk, and the outer sides of the two pressing rods are meshedly connected to transmission gears through the pressing rods, and the outer sides of the two transmission gears are meshedly connected to moving rods through racks, and the two moving rods are slidably installed through the upper and lower ends of the interior of the sealing disk, and the inner ends of the two moving rods are connected to positioning plates through screws.

[0014] Preferably, both transmission gears are grooved with torsion springs, and the two torsion springs have the same structure. The inner ends of the two torsion springs are connected to sealing disks, and both transmission gears are rotatably installed at the upper and lower ends of the sealing disk.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] (1) An inner coating is provided, wherein an outer coating is applied on the outer side of the stainless steel pipe body, and then an inner coating is applied on the inner side of the stainless steel pipe body. Because both the outer coating and the inner coating are made of ceramic coating materials, the stainless steel pipe body can be double-insulated and anti-statically protected by the outer coating and the inner coating, thereby avoiding leakage of the stainless steel pipe body during use, and improving the safety of the stainless steel pipe body;

[0017] (2) An outer insulation layer and an inner insulation layer are provided.

Then, the outer sides of the two pressing rods are connected with transmission gears through rack meshing. When the two pressing rods are pressed and retracted, the two transmission gears can be driven to rotate simultaneously through the two racks. At this time, the two transmission gears can also drive the positioning plates connected by the screws at the inner ends of the two moving rods to retract and move simultaneously through the racks, so that the stainless steel pipe body can be quickly disassembled, assembled and replaced, which is more practical and more time-saving and labor-saving.

[0020] (5) A torsion spring is provided. The torsion spring is provided in a groove inside the two transmission gears. Then, the inner ends of the two torsion springs are connected to the inner wall of the sealing disk. The elastic force of the two torsion springs can be used to elastically reset the positions of the two transmission gears after being pressed and rotated, so as to facilitate the automatic positioning and installation of the stainless steel pipe body at a later time.

[0031] Embodiment 1, in order to solve the problem that the existing stainless steel pipe body 1 cannot be double-insulated, thus causing leakage of the stainless steel pipe body 1 during use, discloses:

[0032] The stainless steel pipe body 1 has a cylindrical surface, and a sealing disc 6 is installed on the outer end of the stainless steel pipe body 1 by sealing welding, and the diameter of the sealing disc 6 is larger than the diameter of the stainless steel pipe body 1;

[0033] It also includes: a stainless steel pipe body 1, an outer coating 2 is arranged on the outer side of the stainless steel pipe body 1, and an inner coating 3 is arranged on the inner side of the stainless steel pipe body 1, and both the outer coating 2 and the inner coating 3 are made of ceramic coating materials.

[0035] like Figure 1-Figure 3As shown, when the stainless steel pipe body 1 is in use, the outer coating 2 and the inner coating 3 arranged on the inner and outer layers can provide double insulation protection for the stainless steel pipe body 1, thereby avoiding leakage and electric shock when the stainless steel pipe body 1 is used in the later stage, thereby improving the safety of the use of the stainless steel pipe body 1, and then the outer insulation layer 4 and the inner insulation layer 5 arranged on the inner and outer sides of the stainless steel pipe body 1 can increase the overall thermal insulation performance of the stainless steel pipe body 1, thereby improving the service life of the stainless steel pipe body 1.

[0036] Embodiment 2 is different from Embodiment 1 in that the stainless steel pipe body 1 can be quickly disassembled, assembled and replaced, which is more practical and more time-saving and labor-saving. The following is disclosed:

[0037] The sealing disk 6 has positioning plates 10 at both ends thereof, and the two positioning plates 10 are both semicircular in shape, and the inner sides of the two positioning plates 10 correspond to the stainless steel pipe body 1, and the inner sides of the two positioning plates 10 are both fitted with anti-skid pads 11, and the structures of the two anti-skid pads 11 are the same, and the inner sides of the two anti-skid pads 11 are fitted and connected to the outer wall of the stainless steel pipe body 1.
