Description

Technical Field

[0001] This utility model relates to the field of DC regulated power supply technology, specifically a DC regulated power supply with adjustable installation height. Background Technology

[0002] A DC regulated power supply is an electronic device that provides a stable DC power supply to a load. When the voltage of the AC power supply or the resistance of the load changes, the DC output voltage of the DC regulated power supply remains stable. The output voltage of a DC regulated power supply is generally adjusted by a conventional potentiometer.

[0003] Existing conventional DC regulated power supplies, such as the Shaneng KDW660 / 24B mining explosion-proof and intrinsically safe DC regulated power supply, are directly fixed to a fixed object using fixing bolts during installation. This makes it inconvenient to adjust the installation height. Uneven terrain in mines can easily lead to water accumulation, affecting normal operation and reducing its practicality. Therefore, we propose a DC regulated power supply with adjustable installation height. Utility Model Content

One end of the first transmission shaft is fixedly connected to a threaded rod.

[0009] Preferably, a DC regulated power supply body is provided on the top of the mounting base.

[0010] Preferably, the mounting base has a first sliding groove inside, and a sliding plate is slidably connected inside the first sliding groove. One end of the second drive shaft extends into the first sliding groove and is fixedly connected to a hexagonal rotating block. The sliding plate has two corresponding slots inside. The mounting base has a second sliding groove inside and on one side of the first sliding groove. A second slider is slidably connected inside the second sliding groove, and one end of the second slider is engaged inside the slot.

[0011] Preferably, the second slide groove has two corresponding first slide rods fixedly connected inside. The first slide rods pass through the second slide block and are slidably connected to it. A telescopic spring is provided on the outside of the first slide rod.

[0012] This utility model provides a DC regulated power supply with easily adjustable installation height, which has the following advantages:

[0013] 1. This adjustable DC regulated power supply allows for height adjustment by rotating a hexagonal block, which in turn drives the second drive shaft and worm gear to rotate. This, in turn, drives the worm wheel and the first drive shaft to rotate, which in turn drives the threaded rod to rotate and push the lifting rod to slide inside the lifting groove. This allows for height adjustment of the mounting base and the DC regulated power supply body according to site conditions, thus improving the practicality of this adjustable DC regulated power supply.

[0014] 2. This adjustable DC power supply, when raised or lowered, causes two sets of adjusting blocks to slide within the adjusting groove, which in turn moves two sets of first connecting blocks, causing the two sets of rotating rods to rotate. After the mounting base is raised or lowered, the first connecting blocks are fixed to the mounting base with fixing bolts, thus allowing the two sets of rotating rods to support the mounting base and improving the stability of the adjustable DC power supply after installation.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a DC regulated power supply with convenient adjustment of installation height, including a mounting base 1, a mounting rod 2 fixedly connected to the bottom of the mounting base 1, a lifting groove 3 opened inside the mounting rod 2, a lifting rod 4 slidably connected inside the lifting groove 3, a threaded rod 5 rotatably connected inside the lifting groove 3 via a bearing, the threaded rod 5 being threadedly connected to the lifting rod 4, two corresponding adjustment grooves 19 opened inside the mounting base 1, two corresponding adjustment blocks 21 slidably connected inside the adjustment grooves 19, a first connecting block 22 fixedly connected to the bottom of the adjustment block 21, a rotating rod 23 rotatably connected inside the first connecting block 22 via a rotating shaft, a base plate 25 fixedly connected to the bottom of the lifting rod 4, four corresponding second connecting blocks 24 fixedly connected to the top of the base plate 25, and the other end of the rotating rod 23 rotatably connected to the inside of the second connecting block 24 via a rotating shaft;

[0022] The adjustment groove 19 is fixedly connected to a second slide rod 20, which passes through the two adjustment blocks 21 and is slidably connected to them. The first connecting block 22 is provided with a fixing bolt inside.

[0023] The mounting base 1 has a transmission groove 6 inside. A first transmission shaft 7 is rotatably connected to the inside of the transmission groove 6 via a bearing. A worm gear 8 is fixedly connected to the outside of the first transmission shaft 7 and inside the transmission groove 6. A second transmission shaft 9 is rotatably connected to the inside of the transmission groove 6 via a bearing. A worm 10 is fixedly connected to the outside of the second transmission shaft 9 and inside the transmission groove 6. The worm 10 meshes with the worm gear 8. One end of the first transmission shaft 7 is fixedly connected to the threaded rod 5.

[0024] The top of the mounting base 1 is provided with a DC regulated power supply body 26, model KDW660 / 24B mining explosion-proof and intrinsically safe DC regulated power supply. The mounting base 1 has a first slide groove 12 inside, and a slide plate 13 is slidably connected inside the first slide groove 12. One end of the second drive shaft 9 extends into the interior of the first slide groove 12 and is fixedly connected to a hexagonal rotating block 11. The slide plate 13 has two corresponding slots 14 inside. The mounting base 1 has a second slide groove 16 inside and on one side of the first slide groove 12. The second slide groove 16 has a second slider 15 slidably connected inside, and one end of the second slider 15 is engaged inside the slot 14.

[0025] The second slide groove 16 has two corresponding first slide rods 17 fixedly connected inside. The first slide rods 17 pass through the second slider 15 and are slidably connected to it.

Finally, using an electric wrench to rotate the hexagonal rotating block 11 drives the second drive shaft 9 and the worm gear 10 to rotate, which in turn drives the worm wheel 8 and the... A drive shaft 7 rotates, thereby driving the threaded rod 5 to rotate and then pushing the lifting rod 4 to slide inside the lifting groove 3. This allows the height of the mounting base 1 and the DC regulated power supply body 26 to be adjusted according to the site conditions. When the mounting base 1 is raised or lowered, it will drive two sets of adjusting blocks 21 to slide correspondingly inside the adjusting groove 19, thereby driving two sets of first connecting blocks 22 to move accordingly, and then driving two sets of rotating rods 23 to rotate. After the mounting base 1 is raised or lowered, the first connecting blocks 22 are fixed to the mounting base 1 by fixing bolts, so that the two sets of rotating rods 23 can support the mounting base 1 and improve stability.
