The interior of the regular hexagonal prism of the locking and fixing column 3 is provided with a front-to-back threaded hole, which is convenient for the anti-rotation and anti-loosening column 4 to be installed by thread. The interior of the threaded hole of the locking and fixing column 3 is provided with a front-to-back anti-rotation and anti-loosening column 4, which is convenient for stopping the rotation of the locking and fixing column 3. The inner side of the anti-rotation and anti-loosening column 4 is provided with a threaded column, which is convenient for installation by thread. The outer end face of the threaded column of the anti-rotation and anti-loosening column 4 is provided with a regular hexagonal prism, which is convenient for rotating and disassembling by tools.

[0029] Among them, an upper heat exchange plate 5 arranged in the front and back directions is placed on the top between the circulation tubes of the heat exchange circulation tube 2, which is convenient for combining with the lower heat exchange plate 6 to limit the position on the circulation tube of the heat exchange circulation tube 2. Square holes are opened on both ends of the upper heat exchange plate 5 to pass through the left and right, which is convenient for the combination limit rod 7 to be inserted to stop rotation. An inverted U-shaped fitting groove is opened on the bottom end face of the upper heat exchange plate 5 to pass through the front and back directions, which is convenient for fitting with the annular groove of the heat exchange circulation tube 2. A corrosion-resistant layer is provided on the surface of the upper heat exchange plate 5 to increase the service life. A lower heat exchange plate 6 in the front and back directions is provided on the left side of the upper heat exchange plate 5 to facilitate the combination with the upper heat exchange plate 5 to limit the position on the circulation tube of the heat exchange circulation tube 2. Square holes are opened on both ends of the lower heat exchange plate 6 to pass through the left and right, which is convenient for the combination limit rod 7 to be inserted To prevent rotation, the top end face of the lower heat exchange plate 6 is provided with a U-shaped fitting groove that runs through the front and back and is convenient for fitting with the annular groove of the heat exchange circulation pipe 2. The surface of the lower heat exchange plate 6 is provided with a corrosion-resistant layer to facilitate increasing the service life. Combination limit rods 7 in the left and right directions are inserted at both ends between the lower heat exchange plate 6 and the upper heat exchange plate 5 to facilitate preventing the lower heat exchange plate 6 and the upper heat exchange plate 5 from falling off. A square rod is provided in the middle of the combination limit rod 7 to facilitate insertion into the square holes of the lower heat exchange plate 6 and the upper heat exchange plate 5. Threaded columns are provided on the left and right end faces of the square rod of the combination limit rod 7 to facilitate nut installation. Two nuts are installed on the threaded column of the combination limit rod 7 to facilitate preventing the combination limit rod 7 from falling off by the nuts, and to prevent loosening by the double nut structure.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In the present utility model, Figure 1 As shown, the heat exchange circulation pipe 2 is in a fixed state, and the four corners at the bottom of the mechanism body 1 are cut-off parts of the bearing block. At this time, the bottom of the locking and fixing column 3 is screwed into the inside of the bearing block, and the heat exchange circulation pipe 2 is pressed against the bearing block through the locking and fixing column 3. The inner end surface of the anti-rotation and anti-loosening column 4 is pressed tightly against the end surface of the shunt pipe of the heat exchange circulation pipe 2, thereby preventing the locking and fixing column 3 from rotating and loosening through the anti-rotation and anti-loosening column 4; when Figure 1 As shown, when the upper heat exchange plate 5 and the lower heat exchange plate 6 are disassembled, the nut on the combined limiting rod 7 is rotated by a tool, so that the nut moves outward through thread engagement and disengages from the threaded column of the combined limiting rod 7, and then the combined limiting rod 7 is pulled out of the square holes of the upper heat exchange plate 5 and the lower heat exchange plate 6, thereby releasing the combined limiting rod 7 from preventing the upper heat exchange plate 5 and the lower heat exchange plate 6 from falling off. The upper heat exchange plate 5 and the lower heat exchange plate 6 can be lifted up and separated from the heat exchange circulation pipe 2 to achieve disassembly. The reverse operation is the installation operation of the upper heat exchange plate 5 and the lower heat exchange plate 6.

[0032] Example 2:

[0033] The difference from Example 1 is that the regular hexagonal prism of the anti-rotation and anti-loosening column 4 can also be set as a regular heptagonal prism, so that the anti-rotation and anti-loosening column 4 can only be rotated by a special tool that cooperates with the regular heptagonal prism, preventing non-staff from rotating and disassembling the anti-rotation and anti-loosening column 4.

[0034] Example 3:

[0035] The difference from the first embodiment is that the left and right end faces of the square rod of the combined limiting rod 7 can also be set to frosted surfaces, thereby increasing the friction between the left and right end faces of the square rod of the combined limiting rod 7 and the nut, preventing the nut from rotating loose.
