[0025] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Example 1: Please refer to Figures 1-6 The utility model provides a technical solution: a quick guide rail connection modular dry-type transformer cross-flow fan, comprising a mounting base 1, a mounting outer frame 21, and a dry-type transformer cross-flow fan body 22 inside the mounting outer frame 21.

[0028] Furthermore, the adjustment and fixing mechanism 3 includes a track adjustment component 31 for adjusting the spacing between the two sets of guide rails according to the installation outer frame 21 of different sizes. A fixed guide rail 311 is provided in the track adjustment component 31, and the fixed guide rail 311 is fixedly installed on the top of the installation base plate 1. A threaded rod 312 is rotatably installed inside the installation base plate 1, and a handle 313 is fixedly installed on the outside of the threaded rod 312. A first movable block 314 is threadedly installed on the outside of the threaded rod 312, and a guide rod 315 is fixedly installed inside the installation base plate 1. A movable guide rail 316 is fixedly installed on the top of the first movable block 314, and a second movable block 317 is slidably installed on the outside of the guide rod 315. The spacing between the fixed guide rail 311 and the movable guide rail 316 can be dynamically adjusted according to the different sizes of the installation outer frame 21 and the dry-type transformer cross-flow fan body 22.

[0029] Furthermore, heat dissipation holes are provided in the fixed guide rail 311 and the movable guide rail 316 to assist the dry-type transformer cross-flow fan body 22 in maintaining a good operating temperature. The top of the second movable block 317 is fixedly installed with the bottom of the movable guide rail 316 to ensure the stability of the position adjustment of the movable guide rail 316.

[0030] Furthermore, the adjustment and fixing mechanism 3 also includes a fixing component 32, in which a first connecting plate 321 is provided inside the fixing component 32, and the first connecting plate 321 is fixedly installed on the top of the fixed guide rail 311, and a second connecting plate 322 is fixedly installed on the outside of the mounting outer frame 21, and a plug-in block 323 is fixedly installed on the outside of the second connecting plate 322, and a mounting seat 324 is fixedly installed on the outside of the first connecting plate 321, and two sets of locking frames 325 are rotatably installed inside the mounting seat 324, and a first spring 326 is provided on the outside of the locking frame 325, so as to facilitate further dynamic locking of the position of the mounting outer frame 21 to avoid the phenomenon of arbitrary position changes of the mounting outer frame 21.

[0031] Furthermore, two groups of locking frames 325 and first springs 326 are provided, and the plug-in blocks 323 are plugged into the cavities formed in the two groups of locking frames 325 to facilitate locking the position of the mounting outer frame 21.

[0032] Example 2: Please refer to Figure 6-Figure 8 , and combined with Example 1, it is further obtained that the safety locking mechanism 4 includes a mounting frame 41, the mounting frame 41 is fixedly installed on the outside of the mounting outer frame 21, a plug-in column 42 is slidably installed inside the mounting frame 41, a connecting column 43 is fixedly installed outside the plug-in column 42, a second spring 44 is provided inside the mounting frame 41, and a plurality of parallel plug-in holes 45 for the plug-in columns 42 to be plugged in are opened on the top of the mounting base plate 1, which is convenient for locking the other side of the mounting outer frame 21 to avoid the phenomenon of the anti-vibration pulley 25 sliding freely during use.

[0033] Furthermore, the second spring 44 is provided between the mounting frame 41 and the plug-in post 42 to facilitate a quick locking effect.

[0034] In the actual operation process, when the dry-type transformer cross-flow fan body 22 needs to be assembled, the dry-type transformer cross-flow fan body 22 can be placed inside the installation outer frame 21, and then the distance between the fixed guide rail 311 and the movable guide rail 316 can be adjusted according to the outer frame size of the installation outer frame 21 and the spacing of the anti-vibration pulley 25. The handle 313 is turned to rotate the threaded rod 312. Under the limiting action of the guide rod 315 and the second movable block 317, the first movable block 314 set outside the threaded rod 312 can be The movable guide rail 316 is movable, thereby changing the position of the movable guide rail 316 to change the distance between the fixed guide rail 311 and the movable guide rail 316. When the distance between the fixed guide rail 311 and the movable guide rail 316 reaches the desired distance, the handle 313 can be stopped to lock the position of the movable guide rail 316. Then, the mounting outer frame 21 can be slid to the inside of the fixed guide rail 311 and the movable guide rail 316 through the anti-vibration pulley 25 and pushed inward. When the plug-in block 323 contacts the two sets of locking frames 325, under the action of the first spring 326, the mounting outer frame 21 can be locked. The two sets of locking frames 325 are rotated to both sides to create a gap so that the plug-in block 323 is plugged into the gap. Then, after stopping the rotation, the locking frame 325 can be restored to its initial position under the action of the first spring 326 to lock the position of the plug-in block 323, thereby avoiding the loosening of the mounting frame 21 during use and ensuring the installation stability. Then, in order to further improve the connection stability of the cross-flow fan body 22 of the dry-type transformer, the connecting column 43 can be pulled upward to make the plug-in column 42 inside the mounting frame 41. After sliding and selecting the plug-in hole 45 at the corresponding position, the connecting column 43 can be loosened. Under the action of the second spring 44, the plug-in column 42 and the plug-in hole 45 at the corresponding position can be restored to the plug-in state, thereby locking the other side of the mounting frame 21 to prevent the anti-vibration pulley 25 from sliding out of the fixed guide rail 311 and the movable guide rail 316 during use. After the fixation is completed, the male terminal 23 and the female terminal 24 can be connected to complete the electrical connection to carry out related work on the dry-type transformer cross-flow fan body 22.
