[0030] Please see Figures 1-5An adjustable-height high-power DC power supply support device includes a frame 1, a lifting transmission mechanism, four-corner limiting mechanisms, and a snap-fit ​​adjustment mechanism. The lifting transmission mechanism includes a base 2, an output shaft 3, a main bevel gear 4, a driven bevel gear 5, a lead screw 6, a lifting frame 7, and a mounting plate 8.

The mounting plate... 8 is installed on the lifting frame 7. The four-corner limiting mechanism includes a mounting plate 9, a limiting frame 10, a side plate 11, a locking tube 12, a locking rod 13, and an adjustment hole 14. The side plate 11 is installed on both sides of the limiting frame 10. One end of the locking rod 13 is installed on the side plate 11. The locking tube 12 is installed at the bottom of the mounting plate 9. Multiple sets of adjustment holes 14 are installed at the bottom of the mounting plate 9, and each set of adjustment holes 14 is connected to a locking tube 12. The locking rod 13 can extend into the locking tube 12 to fix the limiting frame 10 in the required position.

[0031] In this embodiment, the output end of the lifting motor 23 is connected to the output shaft 3, providing rotational power to the output shaft 3. The output shaft 3 drives the main bevel gear 4 mounted on it to rotate. The main bevel gear 4 drives the driven bevel gear 5 connected to it to rotate through meshing. The driven bevel gear 5 is mounted on one end of the lead screw 6. As the driven bevel gear 5 rotates, the lead screw 6 rotates accordingly. The lead screw 6 is rotatably mounted in the frame 1 through a support structure and is threadedly connected to the lifting frame 7. When the lead screw 6 rotates, due to the action of the thread, the lifting frame 7 will move up and down along the axis of the lead screw 6 to achieve height adjustment. The mounting plate 8 is fixedly mounted on the lifting frame 7. By adjusting the position of the lifting frame 7, the installation can be adjusted. The height of plate 8 is adjusted to complete the lifting and lowering adjustment of the power supply support device. The limiting frame 10 is fixed to the mounting plate 9 in a specific position by the snap-fit ​​rod 13. The bottom of the mounting plate 9 is provided with multiple sets of adjustment holes 14, each of which is connected to a snap-fit ​​tube 12. One end of the snap-fit ​​rod 13 is fixedly installed on the side plate 11 of the limiting frame 10, and the other end is inserted into the snap-fit ​​tube 12 on the mounting plate 9. The limiting frame 10 is positioned by mechanical cooperation. The four corner limiting mechanism is provided with four sets of limiting frames 10, which are arranged at the four corners of the frame 1. After the power supply is fixed on the mounting plate 8, the limiting of the limiting frame 10 ensures that the entire device can remain stable and evenly stressed during the lifting and lowering process.

[0032] The snap-fit ​​adjustment mechanism includes a snap-fit ​​groove 15, a spring pin 16, a slope block 17, a turntable 18, a slope groove 19, a spring rod 20, and a bottom ring 21. The snap-fit ​​groove 15 is located on the side wall of the snap-fit ​​rod 13. The spring pin 16 is horizontally installed on the side wall of the snap-fit ​​tube 12 and can extend into the snap-fit ​​groove 15. The slope block 17 is installed at one end of the spring pin 16. The turntable 18 is rotated and limited on the outer wall of the snap-fit ​​tube 12. The slope groove 19 is located on the turntable 18. The bottom ring 21 is fixedly installed on the outer wall of the snap-fit ​​tube 12. Multiple sets of spring rods 20 are slidably installed on the bottom ring 21. One end of the spring rod 20 can push against the bottom end of the turntable 18 step by step, so that the turntable 18 can be supported and rotated. The slope block 17 slides relative to the slope groove 19, so that the spring pin 16 extends into the snap-fit ​​groove 15.

[0033] In this embodiment, the spring pin 16 is horizontally installed on the side wall of the clamping tube 12 and can extend into the clamping groove 15 under the action of the spring to achieve initial clamping and limiting. The slope block 17 is installed on one end of the spring pin 16. The turntable 18 is installed on the outer wall of the clamping tube 12 and has a slope groove 19 at the bottom, which cooperates with the slope block 17. When the turntable 18 rotates, the slope groove 19 causes the slope block 17 to slide, thereby causing the spring pin 16 to retract or extend. The spring rod 20 is installed on the bottom ring 21 and arranged circumferentially. The top of the spring rod 20 supports the bottom of the turntable 18 step by step. When the turntable 18 rotates, the spring rod 20 pushes against the bottom of the turntable 18 step by step to make it rotate stably. At this time, the position of the spring pin 16 is changed by the sliding action of the slope groove 19 and the slope block 17, so as to realize the flexible adjustment and switching of the tightness state of the clamping mechanism.

[0034] Please see Figures 1-5 As a supplementary embodiment of the high-power DC power supply support device for the adjustable height of the lifting transmission mechanism, the four-corner limiting mechanism, and the snap-fit ​​adjustment mechanism: A base plate 22 is installed at the bottom end of the frame 1, and the bottom of the base 2 is fixedly installed on the top end surface of the base plate 22. A lifting motor 23 is installed at the top end of one side of the base plate 22, and the output end of the lifting motor 23 is connected to the output shaft 3. A mounting base 24 and a rotary motor 25 are installed at the top end of the mounting plate 8, and the output end of the rotary motor 25 is connected to the output shaft 3. A rotating gear 26 is installed at the output end of the rotary motor 25. An internal gear ring 28 is installed in the mounting base 24 for limiting rotation. The bottom of the mounting base 24 is connected to the top of the internal gear ring. Four sets of limiting frames 10 are provided and are respectively arranged around the perimeter of the placement plate. A connecting plate 27 is installed at the bottom end of the side wall of the snap-fit ​​tube 12, and the connecting plate 27 is fixedly installed at the bottom end of the mounting base 24 and is connected to the adjustment hole 14.

[0035] More specifically, the user starts the lifting motor 23, which drives the main bevel gear 4 and the driven bevel gear 5 to rotate via the output shaft 3. The driven bevel gear 5 further drives the lead screw 6 to rotate. Since the lifting frame 7 is threadedly connected to the lead screw 6, the rotation of the lead screw 6 will cause the lifting frame 7 to move up and down along the axis of the lead screw 6, thereby realizing the height adjustment of the mounting plate 8 and the power supply device. During the entire lifting process, the four corner limit mechanism constrains the position of the power supply through the limit frame 10. The position of the limit frame 10 can be adjusted by the snap-fit ​​between the snap-fit ​​rod 13 and the snap-fit ​​tube 12. During adjustment, the user can insert and remove the snap-fit ​​rod 13 to change the position of the limit frame 10 to adapt to different requirements and ensure the stability of the equipment. The user rotates the turntable 18 on the outer wall of the snap-fit ​​tube 12, and controls the extension and retraction state of the spring pin 16 through the sliding action of the slope block 17 and the slope groove 19 to realize the loosening or locking of the snap-fit ​​mechanism. The spring rod 20 further stabilizes the position of the turntable 18 by supporting the bottom of the turntable 18 in stages, enhancing the reliability of the snap-fit ​​adjustment.

[0036] In summary, during the use or operation of the overall equipment: when the main mechanism needs to operate, the output end of the lifting motor 23 is connected to the output shaft 3, providing rotational power to the output shaft 3. The output shaft 3 drives the main bevel gear 4 mounted on it to rotate. The main bevel gear 4 drives the connected driven bevel gear 5 to rotate through meshing. The driven bevel gear 5 is mounted on one end of the lead screw 6. As the driven bevel gear 5 rotates, the lead screw 6 rotates accordingly. The lead screw 6 is rotatably mounted in the frame 1 through a support structure and is threadedly connected to the lifting frame 7. When the lead screw 6 rotates, due to the action of the thread, the lifting frame 7 will move up and down along the axis of the lead screw 6 to achieve height adjustment. The mounting plate 8 is fixedly mounted on the lifting frame 7. By adjusting the position of the lifting frame 7, the height of the mounting plate 8 can be adjusted, thereby completing the lifting and lowering adjustment of the power support device.

[0037] When the four-corner limiting mechanism is required to operate, the limiting frame 10 is fixed to the mounting plate 9 in a specific position by the snap-fit ​​rod 13. The bottom of the mounting plate 9 is provided with multiple sets of adjustment holes 14, each of which is connected to a snap-fit ​​tube 12. One end of the snap-fit ​​rod 13 is fixedly installed on the side plate 11 of the limiting frame 10, and the other end is inserted into the snap-fit ​​tube 12 on the mounting plate 9. The limiting frame 10 is positioned by mechanical cooperation. The four-corner limiting mechanism is provided with four sets of limiting frames 10, which are arranged at the four corners of the frame 1. After the power supply is fixed on the mounting plate 8, the limiting of the limiting frame 10 ensures that the entire device can remain stable and evenly stressed during the lifting process.

[0038] When the snap-fit ​​adjustment mechanism is in operation, the spring pin 16 is horizontally mounted on the side wall of the snap-fit ​​tube 12 and can extend into the snap-fit ​​groove 15 under the action of the spring to achieve initial snap-fit ​​and limit. The slope block 17 is mounted on one end of the spring pin 16. The turntable 18 is mounted on the outer wall of the snap-fit ​​tube 12 and has a slope groove 19 at the bottom, which cooperates with the slope block 17. When the turntable 18 rotates, the slope groove 19 causes the slope block 17 to slide, thereby causing the spring pin 16 to retract or extend. The spring rod 20 is mounted on the bottom ring 21 and arranged circumferentially. The top of the spring rod 20 supports the bottom of the turntable 18 step by step. When the turntable 18 rotates, the spring rod 20 pushes against the bottom of the turntable 18 step by step to make it rotate stably. At this time, the position of the spring pin 16 is changed by the sliding action of the slope groove 19 and the slope block 17, so as to realize the flexible adjustment and switching of the tightness state of the snap-fit ​​mechanism.

[0039] The user starts the lifting motor 23, which drives the main bevel gear 4 and the driven bevel gear 5 to rotate via the output shaft 3. The driven bevel gear 5 further drives the lead screw 6 to rotate. Since the lifting frame 7 is threadedly connected to the lead screw 6, the rotation of the lead screw 6 will cause the lifting frame 7 to move up and down along the axis of the lead screw 6, thereby realizing the height adjustment of the mounting plate 8 and the power supply device. During the entire lifting process, the four corner limit mechanism constrains the position of the power supply through the limit frame 10. The position of the limit frame 10 can be adjusted by the snap-fit ​​between the snap-fit ​​rod 13 and the snap-fit ​​tube 12. During adjustment, the user can insert and remove the snap-fit ​​rod 13 to change the position of the limit frame 10 to adapt to different requirements and ensure the stability of the equipment. The user rotates the turntable 18 on the outer wall of the snap-fit ​​tube 12, and controls the extension and retraction state of the spring pin 16 through the sliding action of the slope block 17 and the slope groove 19 to realize the loosening or locking of the snap-fit ​​mechanism. The spring rod 20 further stabilizes the position of the turntable 18 by supporting the bottom of the turntable 18 in stages, enhancing the reliability of the snap-fit ​​adjustment.

For all the fixed connections mentioned above, welding is preferred.
