[0030] By setting the inclined rib plate 23 and the connecting cover 11, the inclined rib plate 23 can be inserted into the connecting cover 11 to fix the cabinet 10 after the cabinet 10 is completely installed in place, and the connecting cover 11 and the inclined rib plate 23 are completely locked by inserting the pin 14, so as to ensure the firm effect of the final installation.
[0031] As shown, Figures 1-7 The bottom of the cabinet 10 is evenly distributed with a group of insertion holes 26, and the inside of the first base 12 is provided with a group of grating plates 25 which can be inserted into the insertion hole 26 at the corresponding position of each group of insertion holes 26, and each group of grating plates 25 is arranged in staggered arrangement with the corresponding group of inclined rib plates 23 and slides relative to each other.
[0032] By setting the grating plate 25 and the insertion hole 26, the grating plate 25 can be gradually inserted into the insertion hole 26 during the installation of the cabinet 10 in the first base 12, so as to limit the falling process of the cabinet 10, avoid the shaking of the cabinet 10 and affect the stability and accuracy of the installation.
[0033] As shown, Figures 1-7As shown, the first base 12 is rotationally connected with a rotating disc 19 at the bottom side, each sliding plate 21 is provided with a sliding pin 22 at the bottom side, and the rotating disc 19 is provided with an arc-shaped slot 20 at a position corresponding to each sliding pin 22, each arc-shaped slot 20 is slidably connected with the corresponding sliding pin 22, the first base 12 is fixedly connected with a second base 13 at the bottom, the rotating disc 19 is fixedly connected with a worm gear 18 at the bottom, the second base 13 is rotationally connected with a worm shaft 16, the worm shaft 16 is in meshing transmission connection with the worm gear 18, and one end of the worm shaft 16 extending out of the second base 13 is detachably connected with a crank 17.
[0034] The rotating disc 19 is arranged to synchronously drive the four groups of inclined rib plates 23 to slide, thereby achieving the installation and guidance of the cabinet 10, and the worm gear 18 and the worm shaft 16 are arranged to achieve the effect of driving the rotating disc 19 to rotate.
[0035] As shown, Figures 1-7 The first base 12 is provided with a through air hole 15 at a position corresponding to each grid plate 25, each grid plate 25 is provided with a chamfer 27 at the end, the cabinet 10 is fixedly connected with a partition plate 28 above the inclined surface at the bottom of the cabinet 10, and the partition plate 28 is uniformly provided with a through slot 29.
[0036] The partition plate 28 is arranged to facilitate the installation and placement of the equipment in the cabinet 10, and the through slot 29 and the air hole 15 are arranged to communicate the inside and outside of the cabinet 10, facilitate the exchange of gas and heat, and achieve a better cooling effect in the cabinet 10.
[0037] In this embodiment, initially, the cabinet 10 has not been installed into the first base 12, at this time, the four sliding plates 21 are gathered together, the inclined surface of each group of inclined rib plates 23 is flush with the end of the corresponding grid plate 25, and the insertion pin 14 has not been inserted into the connecting cover 11.
[0038] When installation is needed, the operator hoists the cabinet 10 by a hoisting tool and moves it above the first base 12, then slowly lowers the cabinet 10, and the bottom inclined surface of the cabinet 10 is attached to the inclined surface of the inclined rib plate 23, due to the guidance of the inclined surface, the cabinet 10 is finally accurately landed at the center position of the first base 12.
[0039] Subsequently, the operator will connect the handle 17 in the end of the worm 16, manually shake the handle 17, so that the worm 16 drives the worm gear 18 to rotate, in turn, the rotating disc 19 rotates, then due to the sliding connection of the arc-shaped groove 20 and the sliding pin 22, each sliding plate 21 slides in the opposite direction synchronously, then each group of inclined rib plates 23 gradually expands away, under the action of gravity, the cabinet 10 gradually falls, at the same time, the inclined surface of the inclined rib plate 23 and the inclined surface of the bottom of the cabinet 10 slide with each other, because the inclined rib plate 23 moves synchronously, the inclined rib plate 23 still positions and guides the cabinet 10 in the process, and the cabinet 10 is always positioned at the center of the first base 12.
[0040] At the same time, due to the falling of the cabinet 10, and the inclined rib plates 23 away from each other, the grid plate 25 is exposed and gradually inserted into the corresponding insertion hole 26, so that the position of the cabinet 10 is limited during the falling process of the cabinet 10, to avoid the cabinet 10 from deviating and misplacing due to vibration, and effectively avoid the cabinet 10 from tilting, thereby ensuring the stability of the installation process.
[0041] When the cabinet 10 is completely fitted with the sliding plate 21 at the bottom end, the cabinet 10 reaches the installation position and is completely installed in place, at this time, the top end of the inclined rib plate 23 is inserted into the connecting cover 11, thereby fixing the cabinet 10, so that the cabinet 10 is not easy to separate from the first base 12, ensuring the firmness of the installation, then the operator inserts the bolt 14 into the connecting cover 11, locks and connects the connecting cover 11 with the corresponding inclined rib plate 23, further improves the firmness of the installation, avoids the cabinet 10 from separating from the first base 12 due to vibration or misoperation.
[0042] After the installation is completed, the operator can remove the handle 17, to avoid unrelated personnel from operating, and at this time, the grid plate 25 is inserted into the cabinet 10, the grid plate 25 is in communication with the through groove 29, so that the inside of the cabinet 10 can exchange gas and temperature with the outside, to achieve better cooling effect of the inside of the cabinet 10, and improve the service life of the equipment in the cabinet 10.
