Description

Technical Field

[0001] This utility model relates to the field of power converter technology, specifically a power converter that can be quickly assembled and disassembled. Background Technology

[0002] A power converter is a device that converts one form of power to another. It is typically used to change the type of voltage, frequency, or current. It mainly includes boost converters, buck converters, positive feedback converters, inverters, and rectifiers, and is widely used in electronic equipment, renewable energy systems (such as solar and wind power), electric vehicles, and industrial automation.

[0003] Traditional power converters are typically installed and secured using bolts. Disassembly, maintenance, or replacement requires removing each bolt individually, which is cumbersome. Furthermore, subsequent reinstallation also requires rotating each bolt to secure the converter. To address these issues, we propose a power converter that allows for quick assembly and disassembly.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figure 1-6 As shown, this utility model provides a power converter that can be quickly assembled and disassembled, including a base plate 1, a power converter body 2 at the top of the base plate 1, a first fixing mechanism 3 fixedly installed on one side of the top of the base plate 1, and a second fixing mechanism 4 at the side of the top of the base plate 1 away from the first fixing mechanism 3.

[0028] The first fixing mechanism 3 includes a fixing frame 31. The first fixing mechanism 3 is fixedly installed on one side of the top of the base plate 1 through the fixing frame 31. A first fixing member 32 is rotatably provided on one side of the fixing frame 31. A sliding frame 33 is slidably provided on the side of the top of the fixing frame 31 away from the first fixing member 32. A second fixing member 34 is rotatably provided in the middle of the sliding frame 33 to facilitate the sliding of the second fixing member 34 and adjust the distance between the first fixing member 32 and the second fixing member 34 to adapt to the installation and fixing of power converter bodies 2 of different sizes.

[0029] The first fixing member 32 includes a fixed outer cylinder 321. A fixing bolt 322 is slidably mounted in the middle of the fixed outer cylinder 321. A ball bearing 3221 is slidably mounted on the outer wall of the end of the fixing bolt 322. The ball bearing 3221 contacts the inner wall of the fixed outer cylinder 321. The fixing bolt 322 can slide up and down in the fixed outer cylinder 321. A limit ring 323 is fixedly installed at the bottom end of the fixed outer cylinder 321. A spring 324 is provided at the top end of the limit ring 323. The first fixing member 32 is rotatably mounted on one side of the fixed outer frame 31 through the fixed outer cylinder 321. The structure of the second fixing member 34 is the same as that of the first fixing member 32. The second fixing member 34 is rotatably mounted in the middle of the sliding frame 33 through the fixed outer cylinder 321.

[0030] Two symmetrically distributed mounting plates 21 are fixedly installed on the bottom outer side of the power converter body 2. The top of the mounting plate 21 is welded with a fixing nut 22 that works with the fixing bolt 322.

[0031] Both the first fixing member 32 and the second fixing member 34 have crown gears 35 fixedly installed at the bottom of the fixing outer cylinder 321. A drive shaft 36 is rotatably mounted at the bottom of the fixing outer frame 31. A first gear 351 is fixedly installed on the side of the drive shaft 36 near the first fixing member 32, and the first gear 351 meshes with the crown gear 35 at the bottom of the first fixing member 32. A long gear 352 is fixedly installed on the side of the drive shaft 36 near the second fixing member 34, and the long gear 352 meshes with the crown gear 35 at the bottom of the second fixing member 34. The drive shaft 36 is near the first gear... A worm gear 37 is fixedly installed on one side of the wheel 351. A worm 371 is meshed with the outer side of the worm gear 37. The worm 371 is rotatably installed in the fixed outer frame 31. A drive column 372 is fixedly installed at the top of the worm 371. The drive column 372 is rotated manually with a tool, which drives the worm 371 to drive the worm gear 37 to rotate, thereby controlling the drive shaft 36 to rotate. This drives the first gear 351 and the long gear 352 to rotate synchronously, and drives the crown gear 35 to rotate synchronously. This drives the fixed outer cylinder 321 in the first fixed member 32 and the second fixed member 34 to rotate synchronously.

[0032] The structure of the second fixing mechanism 4 is the same as that of the first fixing mechanism 3. In the second fixing mechanism 4, slide blocks 11 are fixedly installed on both sides of the bottom end of the fixing frame 31. The slide blocks 11 are slidably engaged on the base plate 1, which facilitates the sliding of the second fixing mechanism 4 and the adjustment of the distance between the first fixing mechanism 3 and the second fixing mechanism 4, so as to adapt to the installation and fixing of power converter bodies 2 of different sizes.

[0033] In the first fixing mechanism 3 and the second fixing mechanism 4, the fixing bolts 322 are respectively threaded onto the corresponding fixing nuts 22 to fix the power converter body 2.

[0034] A shock-absorbing pad 325 is fixedly installed at the top of the fixed outer cylinder 321. The lower surface of the mounting plate 21 is in contact with the upper surface of the shock-absorbing pad 325. By setting the shock-absorbing pad 325, the power converter body 2 is subjected to shock absorption.

[0035] Working principle: When disassembling the power converter body 2, simply use a tool to rotate the drive column 372 in the first fixing mechanism 3 and the second fixing mechanism 4. This drives the worm gear 371 to rotate the worm wheel 37, thereby controlling the drive shaft 36 to rotate. This, in turn, drives the first gear 351 and the long gear 352 to rotate synchronously, which in turn drives the crown gear 35 to rotate synchronously. This, in turn, drives the outer cylinder 321 and the fixing bolt 322 in the first fixing part 32 and the second fixing part 34 to rotate synchronously. Since the fixing bolt 322 and the fixing nut 22 are threaded, the fixing bolt 322 slides down in the outer cylinder 321. The fixing bolt 322 gradually disengages from the fixing nut 22, and the fixing bolt 322 compresses the spring 324, allowing for quick disassembly of the power converter body 2. This eliminates the need to rotate and disassemble each bolt individually, making it simple and convenient.

[0036] When it is necessary to install and fix the power converter body 2, first adjust the second fixing mechanism 4 according to the position of the mounting plate 21 in the power converter body 2, and adjust the second fixing part 34 in the first fixing mechanism 3 and the second fixing mechanism 4 until the fixing bolt 322 and the fixing nut 22 are vertically aligned, so as to adapt to the installation and fixing of power converter bodies 2 of different sizes.

[0037] Subsequently, the drive column 372 in the first fixing mechanism 3 and the second fixing mechanism 4 is rotated in the opposite direction, which drives the worm gear 371 to drive the worm wheel 37 to rotate in the opposite direction, thereby controlling the drive shaft 36 to rotate in the opposite direction. This, in turn, drives the first gear 351 and the long gear 352 to rotate synchronously, and drives the crown gear 35 to rotate synchronously in the opposite direction. This, in turn, drives the fixed outer cylinder 321 and the fixing bolt 322 in the first fixing member 32 and the second fixing member 34 to rotate synchronously in the opposite direction. The fixing bolt 322 is threaded onto the corresponding fixing nut 22 to install and fix the power converter body 2.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
