DETAILED DESCRIPTION

[0024] In order to make the purpose and advantages of the utility model more clear and apparent, the utility model is specifically described below in combination with embodiments. It should be understood that the following text is merely used to describe one or several specific embodiments of the utility model, and does not strictly limit the scope of protection specifically requested by the utility model. As used in this text, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include reasonable and inconsistent tolerances for machining or human error;

[0025] In combination Figures 1 to 4 As shown, the specific features of the quick heat dissipation special-shaped alloy resistance structure are described in detail below:

[0026] The quick heat dissipation special-shaped alloy resistance structure comprises an alloy resistance body 1, the bottom of the alloy resistance body 1 is fixedly provided with a heat dissipation fin 2, the heat dissipation fin 2 can expand the contact area between the alloy resistance body 1 and air, thereby improving the heat exchange efficiency of the alloy resistance body 1, so that the alloy resistance body 1 can be quickly cooled, both ends of the alloy resistance body 1 are fixedly provided with connecting plates 3, the inner wall of the connecting plate 3 is slidably connected with a sliding block 4, the inner wall of the sliding block 4 is threadedly connected with a bolt 41, the connecting plate 3 is provided with an adjusting mechanism 5, the adjusting mechanism 5 can adjust the distance between the two groups of bolts 41, so that the alloy resistance body 1 is more flexible to install and more convenient to use, the adjusting mechanism 5 is provided with a positioning mechanism 6, the positioning mechanism 6 can prevent the bolt 41 from loosening, thereby improving the installation stability of the alloy resistance body 1.

[0027] The above-mentioned adjusting mechanism 5 comprises a sliding plate 51, an inclined groove 52, a threaded rod 53, a knob 54 and a guide rod 55; the sliding plate 51 is slidably connected to the inner wall of the connecting plate 3, the inclined groove 52 is formed in the sliding plate 51, the threaded rod 53 is rotatably connected to the inner wall of the connecting plate 3, the knob 54 is fixedly installed at the end of the threaded rod 53 away from the connecting plate 3, the threaded rod 53 is threadedly connected to the sliding plate 51, the guide rod 55 is fixedly installed on the outer wall of the sliding block 4, and the outer wall of the guide rod 55 is attached to the inner wall of the inclined groove 52.

[0028] Rotating the threaded rod 53 by the knob 54, along with the sliding plate 51, the inclined groove 52 and the guide rod 55, can drive the two sets of sliders 4 to move synchronously in opposite directions on the inner wall of the connecting plate 3. This allows the spacing between the two sets of bolts 41 to be adjusted so that the bolts 41 can enter the bolt holes at the installation location. This allows the alloy resistor body 1 to adapt to different installation requirements, making the installation of the alloy resistor body 1 more flexible.

[0029] The aforementioned positioning mechanism 6 includes a rotating rod 61, a positioning plate 62, and a torsion spring 63. One end of the rotating rod 61 is rotatably connected to the inner wall of the guide rod 55, and the other end of the rotating rod 61 is fixedly installed with the positioning plate 62. The bottom of the positioning plate 62 is attached to the top of the bolt 41, and a torsion spring 63 is provided at the connection between the rotating rod 61 and the guide rod 55.

[0030] The elastic interaction between the torsion spring 63 and the rotating rod 61 allows the positioning plate 62 to be attached to the top of the bolt 41. The positioning plate 62 can limit the height of the bolt 41, preventing the bolt 41 from loosening due to equipment vibration, thereby improving the stability of the alloy resistor body 1 after installation.

[0031] When using this irregular alloy resistor structure, the alloy resistor body 1 can be installed using bolts 41 and sliders 4. If there is a misalignment between the bolt hole and bolt 41 at the installation location, the threaded rod 53 is rotated using knob 54, causing it to rotate on the inner wall of the connecting plate 3. Simultaneously, the rotation of the threaded rod 53 drives the threaded sliding plate 51 to slide on the inner wall of the connecting plate 3. As the sliding plate 51 slides, the inclined groove 52 presses against the guide rod 55, causing the guide rod 55 to push the slider 4. At this time, the slider 4 slides on the inner wall of the connecting plate 3, and the two sets of sliders 4 move synchronously in opposite directions. This allows adjustment of the distance between the two sets of bolts 41, enabling the bolts 41 to enter the bolt holes at the installation location, thus ensuring proper mounting. The alloy resistor body 1 adapts to different installation requirements, making its installation more flexible and its use more convenient. When it is necessary to disassemble the bolt 41, rotate the rotating rod 61 to compress the torsion spring 63 and drive the positioning plate 62 to disengage from the top of the bolt 41. At this time, the bolt 41 can be rotated to separate it from the slider 4. After the bolt 41 and the slider 4 are threaded together, release the rotating rod 61. At this time, the torsion spring 63 will drive the rotating rod 61 to rotate and reset. Simultaneously, the rotating rod 61 will drive the positioning plate 62 to fit against the top of the bolt 41. The positioning plate 62 can limit the height of the bolt 41, preventing the bolt 41 from loosening due to equipment vibration, thereby improving the stability of the alloy resistor body 1 after installation.
