[0024] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0025] A pipe heater that is convenient for assembly, including a housing 1. An inner pipe assembly 2 is slidably connected inside the housing 1. A heating element 3 is slidably connected inside the inner pipe assembly 2. The inner pipe assembly 2 includes a rubber gasket 21. A connecting assembly 22 is slidably connected inside the rubber gasket 21. The connecting assembly 22 includes a first perforated pipe 221. A first hole on the pipe 222 is provided on the outer side of the first perforated pipe 221. One end of the first perforated pipe 221 is fixedly connected to a flange 223. A first threaded hole 224 is provided inside the flange 223. A rotating groove 225 is provided inside the flange 223. A ball 226 is installed inside the rotating groove 225. A rotating groove between the disks 227 is provided on one side of the flange 223. A rotating assembly 23 is rotatably connected inside the connecting assembly 22. The rotating assembly 23 includes a second perforated pipe 231. A second hole on the pipe 232 is provided on the outer side of the second perforated pipe 231. One end of the second perforated pipe 231 is fixedly connected to a rotating ring 233. A limiting short column 234 is fixedly connected to one side of the rotating ring 233. A limiting gasket assembly 24 is rotatably connected outside the rotating assembly 23. The limiting gasket assembly 24 includes a perforated gasket 241. A second threaded hole 242 is provided inside the perforated gasket 241. A limiting groove 243 is provided inside the perforated gasket 241.

[0026] As a further implementation of this solution, the central axes of the rubber gasket 21 and the connecting assembly 22 are on the same straight line. The included angle between the rotating assembly 23 and the rubber gasket 21 is 90°. The limiting gasket assembly 24 is parallel to the rubber gasket 21. Such a design makes the structure of the device more reasonable and avoids interference between components.

[0027] As a further implementation of this solution, the central axes of the first perforated pipe 221 and the housing 1 are on the same straight line. The included angle between the first perforated pipe 221 and the flange 223 is 90°. A number of first threaded holes 224 are provided. The first threaded holes 224 are evenly distributed in a ring shape on the inner side of the flange 223. Such a design is more reasonable and is conducive to the mutual support between components.

[0028] As a further implementation of this solution, the inner side of the rotating groove 225 fits with the outer side of the rotating ring 233. A number of balls 226 are provided. The balls 226 are evenly distributed in a ring shape on the inner side of the rotating groove 225. Such a design strengthens the mutual support between components and improves the stability of the device.

[0029] As a further implementation of this solution, the outer side of the second perforated pipe 231 fits with the inner side of the first perforated pipe 221. The second perforated pipe 231 and the rotating ring 233 have the same axis. A number of second holes on the pipe 232 are provided. The second holes on the pipe 232 correspond to the first holes on the pipe 222 one by one. Such a design strengthens the engagement between the components of the device and is conducive to the operation of the device.

[0030] As a further implementation of this solution, the outer side of the rotating ring 233 is in contact with the ball 226. The rotating ring 233 is annular in shape. The included angle between the limiting short post 234 and the rotating ring 233 is 90°. There are two limiting short posts 234, and the two limiting short posts 234 are symmetrically distributed up and down on one side of the rotating ring 233. Such a design is beneficial to improving the operating efficiency of the device;

[0031] As a further implementation of this solution, there are several second threaded holes 242, and the second threaded holes 242 correspond to the first threaded holes 224 one by one. The limiting short post 234 is rotatably connected to the inside of the limiting groove 243. There are two limiting grooves 243, and the two limiting grooves 243 are symmetrically distributed up and down on the inside of the opening gasket 241. Such a design is more reasonable and beneficial to improving the installation accuracy of the device components.

[0032] Working process: During the use of the device, insert the inner tube assembly 2 into the housing 1, and then insert the heating element 3 into the inner tube assembly 2. Use bolts to fix the housing 1, the inner tube assembly 2, and the heating element 3. When the heating element 3 needs to be repaired, keep the positions of the housing 1 and the inner tube assembly 2 unchanged, and rotate the heating element 3. When the heating element 3 rotates, it will drive the limiting short post 234 to rotate in the limiting groove 243. When the limiting short post 234 rotates, the limiting short post 234 will drive the rotating ring 233 to rotate in the rotating groove 225. The setting of the ball 226 can reduce the friction generated between the rotating ring 233 and the flange 223 when the rotating ring 233 rotates. When the rotating ring 233 rotates, it will drive the second perforated tube 231 to rotate. When the limiting short post 234 rotates a certain angle in the limiting groove 243, the opening gasket 241 will restrict the limiting short post 234. At the same time, the second perforated tube 231 will block the first tube hole 222 opened on the first perforated tube 221, and the medium in the housing 1 will no longer flow into the inner tube assembly 2. At this time, take out the heating element 3 for repair, and then insert the heating element 3 through the limiting gasket assembly 24 into the inside of the connecting assembly 22. Rotate the limiting short post 234 to align the limiting short post 234 with the hole opened on the heating element 3, and fix the heating element 3 with the rubber gasket 21, the connecting assembly 22, and the limiting gasket assembly 24 through bolts.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
