Description

Technical Field

[0001] The utility model relates to the technical field of AC frequency converters, in particular to an AC frequency converter with multiple installation modes. Background Art

[0002] The frequency converter is an electric power control device that applies frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification, filtering, inversion, braking unit, drive unit, detection unit and microprocessing unit.

[0003] For example, a frequency converter for AC speed regulation with the authorization announcement number CN212381146U, the above document changes the traditional pre-opened wiring holes to the existing one with a wiring board at the bottom of the shell, and a number of wiring holes are arranged inside the wiring board, and the several wiring holes are of a knocking structure, so that they are sealed when not in use, and only need to be knocked lightly when in use. However, during the use of the AC frequency converter in the above document, since the installation method of the AC frequency converter in the above document is relatively simple, it is impossible to fix the AC frequency converter by clamping, and the AC frequency converter can only be fixed by a fixing plate with bolts. Since this fixing method has a relatively small contact area with the installation position of the AC frequency converter, the connection holes of the fixing plate for connecting the bolts cannot be completely in contact with the installation position, which makes the installation of the AC frequency converter easy to loosen;

[0004] However, when the AC inverter in the above document is fixed at the installation position by a fixing plate, a large number of bolts are used. Therefore, when the AC inverter fails, the AC inverter and the fixing plate need to be disassembled as a whole. Each bolt is rotated a large number of times, which makes the disassembly operation of the AC inverter more cumbersome and inconvenient to disassemble the AC inverter. Utility Model Content

[0005] The utility model aims to solve the problem that the AC inverter cannot be fixed by clamping and the problem that the AC inverter is inconvenient to disassemble, and proposes an AC inverter with multiple installation methods.

[0009] Preferably, two sides of the connecting plate are slidably connected to the fixing seat.

[0010] Preferably, the auxiliary structure includes a guide rod, the top of the guide rod is rotatably connected to the connecting block, the groove of the guide rod is slidably connected to the rotating rod, the end of the rotating rod is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the guide rod, the inner sliding groove of the guide rod is slidably connected to a plurality of round blocks, the outer end of the round block is fixedly connected to the sleeve block, and the sliding groove of the sleeve block is slidably connected to the connecting block.

[0013] The utility model proposes an AC inverter with multiple installation methods, and the beneficial effect is that: the user pulls the clamping plates on both sides outwards to make the fixed blocks on both sides slide along the round block 2, and then rotates the double-headed screw, the double-headed screw drives the threaded blocks on both sides to move inwards, and the threaded blocks drive the connecting plates on both sides to move outwards through the connecting rods. The connecting plates on both sides drive the clamping plates to move outwards through the fixed blocks, and then the clamping plates on both sides are placed at the installation location, and then the double-headed screw is rotated in the opposite direction, so that the double-headed screw drives the threaded blocks on both sides to move inwards, so that the clamping plates on both sides move inwards and fit closely with the installation position, thereby fixing the AC inverter, and fixing the AC inverter by clamping;

[0014] The user moves the rotating rod outward to release the tight contact between the rotating rod and the connecting block, and then rotates the rotating rod. The rotating rod drives the round block to move outward through the guide rod, and the round block drives the sleeve block to move outward along the connecting block, so that the sleeve block and the connecting seat are released, thereby disassembling and repairing the AC inverter. After the repair is completed, the rotating rod is rotated in the same way, and then the AC inverter is reset through the connecting block, and then the guide rod is rotated in the opposite direction to fix the AC inverter.

[0022] Embodiment 1:

[0023] Refer to the attached Figure 1-5 In the present embodiment, an AC inverter with multiple installation methods includes a fixing base 1 and a connecting ear 2. The two sides of the fixing base 1 are fixedly connected to a plurality of connecting ears 2. The left side of the fixing base 1 is fixedly connected to a connecting base 5.

A control panel 7 is provided on the left side of the AC inverter 6. An auxiliary structure 3 is provided inside the connecting block 8. A fixed structure 4 is provided inside the fixing base 1.

[0024] The fixing structure 4 includes a double-headed screw 4a1, both sides of which are rotatably connected to the fixing seat 1, the outer walls of the double-headed screw 4a1 are threadedly connected to the threaded blocks 4a2 on both sides, and the two sides of the threaded blocks 4a2 are rotatably connected to multiple connecting rods 4a3 through pins, and the clamping plates 4a6 on both sides are pulled outward, and the clamping plates 4a6 rotate along the fixing blocks 4a5, so that the fixing blocks 4a5 on both sides slide along the round block 4a7, and then the double-headed screw 4a1 is rotated, and the double-headed screw 4a1 drives the threaded blocks 4a2 on both sides to move inward, and the outer sides of the connecting rods 4a3 on both sides of the threaded block 4a are rotatably connected to the connecting plates 4a4 through pins, and the ends of the connecting plates 4a4 drive the connecting rods 4a3 on both sides to rotate, and the connecting rods 4a3 drive the connecting plates 4a4 on both sides to move the connecting plates 4a4 on both sides outward. 4 drives the fixed block 4a5 to move outward, the fixed block 4a5 drives the clamping plate 4a6 to move outward, and then the clamping plates on both sides are placed at the installation position, and then the double-headed screw 4a1 is rotated in the opposite direction, so that the double-headed screw 4a1 drives the threaded blocks 4a2 on both sides to move inward, so that the clamping plates 4a6 on both sides move inward and fit closely with the installation position, thereby fixing the AC inverter, the outer sides of the connecting rods 4a3 on both sides are rotatably connected to the connecting plates 4a4 through pins, the end of the connecting plate 4a4 is fixedly connected to the fixed block 4a5, the right side of the fixed block 4a5 is rotatably connected to the clamping plate 4a6 through a pin, the slide groove of the clamping plate 4a6 is slidably connected to the round block 4a7, the end of the round block 4a7 is fixedly connected to the fixed block 4a5, and the two sides of the connecting plate 4a4 are slidably connected to the fixing seat 1.

[0025] The auxiliary structure 3 includes a guide rod 303, the top of the guide rod 303 is rotatably connected to the connecting block 8, the groove of the guide rod 303 is slidably connected to the rotating rod 301, the end of the rotating rod 301 is fixedly connected to one end of the spring 302, and the other end of the spring 302 is fixedly connected to the guide rod 303. After the AC inverter 6 is fixed by the fixing seat 1 with bolts, when the AC inverter needs to be repaired, the user moves the rotating rod 301 outward, and the rotating rod 301 drives the spring 302 to stretch, so that the rotating rod 301 and the connecting block 8 are released from being pressed together, and then the rotating rod 301 is rotated. The rotating rod 301 drives the guide rod 303 to rotate through the key slot, and the guide rod 303 drives the round block 1 304 to move outward, and the round block 1 304 drives the sleeve 305 to move outward along the connecting block 8, so that the sleeve 305 and the connecting seat 5 are released from the clamping connection, so that the AC inverter 6 can be disassembled for maintenance.

The movable rod 301 is tightly pressed against the connecting block 8, thereby fixing the AC inverter. In this way, the maintenance of the AC inverter 6 is more convenient. The inner sliding groove of the guide rod 303 is slidably connected with the multiple round blocks 304. The outer end of the round block 304 is fixedly connected with the sleeve block 305.

The contact surfaces between the rotating rod 301 and the connecting block 8 are respectively processed with multiple convex blocks at equal angles. The rotating rod 30 1 and the contact surface of the connecting block 8 are respectively processed with protrusions, so that after the rotating rod 301 and the connecting block 8 are pressed against each other, the protrusions distributed in an annular manner at the bottom of the rotating rod 301 and the protrusions distributed in an annular manner at the top of the connecting block 8 are similar to the meshing of the teeth between gears, and the connecting block 8 is fixed, and the protrusions distributed in an annular manner at the top of the connecting block 8 are restricted by the protrusions distributed in an annular manner at the top of the connecting block 8, thereby limiting the rotating rod 301 and preventing the rotating rod 301 from deflecting. Specifically, the protrusions at the top of the connecting block 8 can also be convex in the shape of a groove to match the protrusions at the bottom of the rotating rod 301. A groove corresponding to the protrusion is set at the top of the connecting block 8, so that the protrusion and the groove cooperate with each other to limit the position, and the middle part of the rotating rod 301 is clamped with the connecting block 8.

[0026] Working principle:

[0027] The user pulls the clamping plates 4a6 on both sides outward, and the clamping plates 4a6 rotate along the fixing blocks 4a5, so that the fixing blocks 4a5 on both sides slide along the round block 4a7, and then rotates the double-headed screw 4a1, and the double-headed screw 4a1 drives the threaded blocks 4a2 on both sides to move inward, and the threaded blocks 4a2 drive the connecting rods 4a3 on both sides to rotate, and the connecting rods 4a3 drive the connecting plates 4a4 on both sides to move outward. The connecting plates 4a4 on both sides drive the fixing blocks 4a5 to move outward, and the fixing blocks 4a5 drive the clamping plates 4a6 to move outward, and then place the clamping plates on both sides at the installation location, and then rotate the double-headed screw 4a1 in the opposite direction, so that the double-headed screw 4a1 drives the threaded blocks 4a2 on both sides to move inward, so that the clamping plates 4a6 on both sides move inward and fit closely with the installation position, thereby fixing the AC inverter and fixing the AC inverter by clamping; the clamping surface of the clamping plate 4a6 can also be provided with anti-skid pads or anti-skid ribs to increase the clamping force.

[0028] After the AC inverter 6 is fixed by the fixing base 1 with bolts, when the AC inverter needs to be repaired, the user moves the rotating rod 301 outward, and the rotating rod 301 drives the spring 302 to stretch, so that the rotating rod 301 and the connecting block 8 are released from being pressed tightly, and then the rotating rod 301 is rotated, and the rotating rod 301 drives the guide rod 303 to rotate through the key slot, and the guide rod 303 drives the round block 1 304 to move outward, and the round block 1 304 drives the sleeve block 305 to move outward along the connecting block 8, so that the sleeve block 305 is disengaged from the connecting seat 5, so that the AC inverter 6 can be disassembled for maintenance. After the maintenance is completed, the rotating rod 301 is rotated in the same way, and then the AC inverter 6 is reset through the connecting block 3, and then the guide rod 303 is rotated in the opposite direction to make the sleeve block 305 engage with the connecting seat 5, and then the rotating rod 301 is released. The elastic force of the spring 302 drives the rotating rod 301 to press against the connecting block 8, so that the AC inverter is fixed. In this way, the maintenance of the AC inverter 6 is more convenient.
