[0027] Example

[0028] The environmentally friendly prefabricated insulated pipe fastener with double-layer hardened protection provided in this embodiment, such as... Figures 1-6 As shown, it includes an insulated pipe 1, with an insulation cotton 4 covering the outside of the insulated pipe 1. A fixing mechanism 3 is provided on one side of the insulated pipe 1. The insulated pipe 1 is used to transport liquids or gases. The insulation cotton 4 is used to protect the insulated pipe 1 and prevent heat loss during actual use. The fixing mechanism 3 is located at one end of the insulated pipe 1 to fix the insulated pipe 1 during use. It can also protect the connection between two insulated pipes 1 and prevent the outer insulation cotton 4 from being squeezed and damaged by traditional installation.

[0029] The fixing mechanism 3 includes an arched mounting bracket 301 disposed on one side of the insulated pipe 1. A first semi-circular fixing ring 302 is disposed inside the arched mounting bracket 301 and below the insulated pipe 1. A second semi-circular fixing ring 303 is disposed inside the arched mounting bracket 301 and above the insulated pipe 1. Evenly distributed support blocks 304 are fixedly installed inside the first and second semi-circular fixing rings 302 and 303. One side of each support block 304 contacts the outer side of the insulated pipe 1. Support blocks 304 are interspersed on both sides of the arched mounting bracket 301. The first bolt 305, through the cooperation of the arched mounting bracket 301, the first semi-circular fixing ring 302, the second semi-circular fixing ring 303 and the support block 304, supports the connection of the two insulated pipes 1 and protects the connection of the two insulated pipes 1. The support block 304 is set to separate the second semi-circular fixing ring 303 from the first semi-circular fixing ring 302 relative to the insulated pipe 1, so as to facilitate the subsequent filling of the insulation device in the gap, thereby meeting the insulation requirements between the two insulated pipes 1.

[0030] A filling cavity 307 is provided on one side of the second semi-circular fixing ring 303. One side of the filling cavity 307 extends to the inner side of the second semi-circular fixing ring 303. The filling cavity 307 is used to inject polyurethane foaming agent between the connection between the first semi-circular fixing ring 302, the second semi-circular fixing ring 303 and the two insulation pipes 1, so as to prevent the interior from being exposed and achieve heat preservation at the same time.

[0031] Two protrusions 313 are fixedly installed on the top of the first semicircular fixing ring 302, and a groove 314 is provided on the bottom of the second semicircular fixing ring 303. The protrusions 313 penetrate into the interior of the groove 314. The cooperation between the protrusions 313 and the groove 314 is used to increase the connection and sealing between the first semicircular fixing ring 302 and the second semicircular fixing ring 303 and increase the stability of their use.

[0032] Connecting plates 312 are fixedly installed on both sides of the first semicircular fixing ring 302 and the second semicircular fixing ring 303. The two connecting plates 312 are fixed together by a second bolt. The second semicircular fixing ring 303 is installed relative to the first semicircular fixing ring 302 through the cooperation between the connecting plates 312 and the second bolt, thereby fixing the heat-insulating pipe 1.

[0033] The arched mounting bracket 301 has a sliding groove 308 inside, and a slider 310 is slidably connected inside the sliding groove 308. A connecting rod 309 is fixedly installed on one side of the slider 310, and one side of the connecting rod 309 is fixedly connected to the first semi-circular fixing ring 302. The first semi-circular fixing ring 302 is installed relative to the arched mounting bracket 301 through the cooperation between the sliding groove 308, the connecting rod 309 and the slider 310, thereby realizing the installation and fixation of the heat-insulating pipe 1.

[0034] An arched mounting bracket 301 has a through cavity 306 located at the top of the slide groove 308. The through cavity 306 and the slide groove 308 are rotatably connected by a threaded rod 311 through a bearing. The threaded rod 311 is connected to the slider 310 by a thread. The through cavity 306 is designed to expose the top of the threaded rod 311 to facilitate the adjustment of the threaded rod 311 during use. In turn, the slider 310 is adjusted to drive the connecting rod 309 and the first semi-circular fixing ring 302 to rise and fall, thereby fixing the insulation pipe 1 of different sizes and fixing the insulation pipe 1 at different heights.

[0035] The outer side of the insulation cotton 4 is covered with a hardened protective sleeve 2. One side of the hardened protective sleeve 2 contacts the arched mounting bracket 301. The hardened protective sleeve 2 is used to protect the insulation cotton 4, thereby increasing the service life of the insulation cotton 4. At the same time, the contact between the two sides of the hardened protective sleeve 2 and the two sides of the arched mounting bracket 301 increases the sealing of the insulation pipe 1, further increasing the insulation performance.

[0036] In use, the insulated pipe 1 is inserted into the arched mounting bracket 301 and the first semi-circular fixing ring 302. Multiple insulated pipes 1 are welded end-to-end. After welding, the arched mounting bracket 301 is moved to the welding point of two insulated pipes 1 and fixed with the first bolt 305. After fixing, rigid polyurethane foam is inserted between the first semi-circular fixing ring 302, the second semi-circular fixing ring 303, the insulated pipe 1, and the support block 304. After installation, the second semi-circular fixing ring 303 is placed on top of the insulated pipe 1, so that the protrusion 313 on the top of the first semi-circular fixing ring 302 penetrates into the groove 3. Inside 14, after installation, the connection between the first semi-circular fixing ring 302 and the second semi-circular fixing ring 303 is achieved through the second bolt and the connecting plate 312. After the connection is completed, polyurethane foam is injected into the inner side of the first semi-circular fixing ring 302 and the second semi-circular fixing ring 303 through the injection cavity 307 to fill the gap, thereby increasing the seal between the insulation pipe 1 and the first semi-circular fixing ring 302 and the second semi-circular fixing ring 303. After the overall installation is completed, the rotation of the threaded rod 311 drives the slider 310, the connecting rod 309 and the first semi-circular fixing ring 302 to rise and fall, thereby adjusting the insulation pipe 1 to the required height.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
