Description

Technical Field

[0001] This utility model relates to the field of frequency converter installation technology, specifically a frequency converter mounting bracket. Background Technology

[0002] A frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control an AC motor by changing the frequency of the motor's operating power supply. A frequency converter mainly consists of a rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, and microprocessor unit. It adjusts the voltage and frequency of the output power supply by switching its internal IGBTs, providing the required power voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. Frequency converters are widely used in various fields, such as powering computer systems and suppressing reverse voltage, frequency fluctuations, and momentary power outages.

[0003] In current technology, independently used frequency converters are usually directly fixed to the side wall of the device by bolts and are tightly attached to the side wall of the device. During the operation of the frequency converter, the electronic components inside it will generate a certain amount of heat. When the heat accumulates to a certain extent, it will affect the normal use of the electrical components inside the frequency converter. The way the frequency converter is directly attached to the outer wall of the device is not conducive to its heat dissipation and will affect its service life to a certain extent.

[0004] Therefore, a frequency converter mounting bracket is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies and the problem that the electronic components inside a frequency converter generate heat during operation, which can affect the normal operation of the electrical components when the heat accumulates to a certain extent, and that the direct bonding and fixing of the frequency converter to the outer wall of the device is not conducive to heat dissipation and affects its service life to a certain extent, a frequency converter mounting bracket is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The inverter mounting bracket of this utility model includes a wall-mounted base plate. A ventilation mounting plate is fixedly connected to the side wall of the wall-mounted base plate by a bracket. A central circular plate is vertically fixed to the center of the side wall away from the wall-mounted base plate of the ventilation mounting plate. An annular groove is opened on the outer wall of the central circular plate. A fixing component is installed on the side wall away from the wall-mounted base plate of the ventilation mounting plate. An inverter body is clamped between the fixing components. The fixing component includes two rotating plates. The central through holes of the two rotating plates are mutually engaged with the annular groove.

[0007] Preferably, both ends of the rotating plate are provided with sliding plates, and a columnar groove is formed between the adjacent side walls of the two sliding plates.

[0008] Preferably, both ends of the rotating plate are vertically fixed with guide rods, one end of each guide rod is fixed with a sliding column, and the sliding column is slidably installed inside the cylindrical groove.

[0009] Preferably, each of the two rotating plates is fixedly connected to a supporting circular plate at its far ends, and the end face of the supporting circular plate is coplanar with the end face of the central circular plate.

[0010] Preferably, a threaded post is fixed at the center of the end face of the supporting circular plate, and the four threaded posts pass through the corner through hole of the inverter body.

[0011] Preferably, the side wall of the wall-mounted base plate is fixedly connected to two elastic retractable rods by a bracket, and an L-shaped limiting plate is fixedly connected between one end of the two elastic retractable rods. One end of the L-shaped limiting plate is in contact with the bottom surface of the inverter body.

[0012] Preferably, the L-shaped limiting plate has a limiting groove on the side wall near the bottom plate of the wall-mounted plate.

[0013] Preferably, a limiting slider is fixedly connected to the center of the side wall of the wall-mounted base plate near the bottom edge, and the limiting slider slides against the limiting slot.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, a ventilation mounting plate is installed and fixed using a bracket on the wall-mounted base plate. The ventilation mounting plate, in conjunction with the fixing components, secures the inverter body. This allows the inverter body to be fixed in a close-fitting, perforated manner instead of being fixed to the outer wall of the device. This ensures that the heat dissipation process generated during inverter operation is not obstructed, guaranteeing stable heat dissipation and preventing heat buildup during inverter operation from adversely affecting the electronic components inside the inverter body, thus extending the device's lifespan.

[0016] In this invention, the ventilation mounting plate is installed on the inverter body by interlocking the annular groove on the side wall of the central circular plate with the opening of the sliding plate. This allows the two rotating plates to rotate relative to each other, and the mutual pulling between the rotating plates and the sliding plate fixes the relative position of the threaded post used to fix the inverter body. This allows the device to ensure its fixing effect on the inverter body within a certain range by controlling the rotation and extension of the fixing components according to the position of the fixing holes of the inverter body, thereby increasing the practicality of the device.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 5This utility model provides a frequency converter mounting bracket, including a wall-mounted base plate 1. A ventilation mounting plate 2 is fixed to the side wall of the wall-mounted base plate 1 via a bracket. A central circular plate 21 is vertically fixed to the center of the side wall away from the wall-mounted base plate 1 on the ventilation mounting plate 2. An annular groove 22 is formed on the outer wall of the central circular plate 21. A fixing assembly 3 is installed on the side wall away from the wall-mounted base plate 1 on the ventilation mounting plate 2. A frequency converter body 4 is clamped between the fixing assemblies 3. The fixing assembly 3 includes two rotating plates 31, and the central through holes of the two rotating plates 31 are mutually engaged with the annular groove 22. The wall-mounted base plate 1 is fixed to an external device. The side wall is fixed to the ventilation mounting plate 2 by a bracket. The ventilation mounting plate 2 serves as the iron wall support structure for the inverter body 4. Its air-ventilated structure ensures that after the inverter body 4 and the ventilation mounting plate 2 are installed against the wall, the ventilation mounting plate 2 will not obstruct the heat dissipation of the inverter body 4 on the wall side, thus ensuring the heat dissipation effect of the inverter body 4. The ventilation mounting plate 2 is fixed to the fixing component 3 by interlocking with the side wall through hole of the rotating plate 31 and the annular groove 22 on the side of the central circular plate 21, and the two fixing components 3 can rotate relative to each other without affecting each other.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, both ends of the rotating plate 31 are provided with sliding plates 32. A cylindrical groove 321 is formed between the adjacent sidewalls of the two sliding plates 32. Guide rods 311 are vertically fixed to both ends of the rotating plate 31. A sliding column 312 is fixed to one end of each guide rod 311 and slidably installed inside the cylindrical groove. Supporting circular plates 322 are fixed to the far ends of the two rotating plates 31. The end face of the supporting circular plate 322 is coplanar with the end face of the central circular plate 21. A threaded column 323 is fixed to the center of the end face of the supporting circular plate 322. Four threaded columns 323 pass through the corner through-hole of the inverter body 4. The rotating plate 31 and the sliding plates 32 are connected by... The guide rod 311's sliding column 312 and the cylindrical groove 321 are linked together, allowing the relative length of the combined rotating plate 31 and sliding plate 32 to be changed within a certain range by pulling. The rotation of the rotating plate 31 also changes the relative position of the threaded column 323 at one end of the sliding plate 32, so as to adapt to the change in the size of the inverter body 4 within a certain range and ensure the clamping function of the fixing component 3 on the inverter body 4. The supporting circular plate 322 and the central circular plate 21, as structures that contact the wall surface of the inverter body 4, need to have coplanar structural features to ensure stable support for the wall surface of the inverter body 4.

[0029] like Figure 1 , Figure 2 and Figure 5As shown, two elastic retractable rods 5 are fixed to the side wall of the wall-mounted base plate 1 via brackets. An L-shaped limiting plate 51 is fixed between one end of the two elastic retractable rods 5. One end of the L-shaped limiting plate 51 contacts the bottom surface of the inverter body 4. A limiting groove 52 is formed on the L-shaped limiting plate 51 near the side wall where the wall-mounted base plate 1 is located. A limiting slider 11 is fixed to the center of the side wall of the wall-mounted base plate 1 near the bottom edge. The limiting slider 11 slides against the limiting groove 52. The elastic retractable rods 5 fixed to the side wall of the wall-mounted base plate 1 via brackets provide elastic retraction force to the L-shaped limiting plate 51, causing the fixing assembly 3 to control the inverter. After the inverter body 4 is clamped and limited, one end of the L-shaped limiting plate 51 can prevent the overall rotation of the inverter body 4 after the direction fixing component 3 is fixed by contacting the bottom surface of the inverter body 4, thus ensuring the installation stability of the inverter body 4. In addition, the structural characteristics of the L-shaped limiting plate 51 following the contraction of the elastic contraction rod 5 can adapt to the relative size changes of the inverter body 4 within a certain range by following the fixing component 3. The wall-mounted base plate 1, through the mutual engagement between the limiting slider 11 and the limiting slot 52, increases the structural stability of its reciprocating motion without hindering its contraction movement.

[0030] Working Principle: The wall-mounted base plate 1 is fixed to the side wall of the external device. It is installed and fixed to the ventilation mounting plate 2 via a bracket. The ventilation mounting plate 2 serves as the iron wall support structure for the inverter body 4. Its elevated ventilation structure ensures that after the inverter body 4 and the ventilation mounting plate 2 are installed against the wall, the ventilation mounting plate 2 will not obstruct the heat dissipation of the inverter body 4 on the wall side, thus ensuring the heat dissipation effect of the inverter body 4. The ventilation mounting plate 2 secures the fixing component 3 by engaging with the annular groove 22 on the side of the central circular plate 21 through the through hole in the side wall of the rotating plate 31. This allows the two fixing components 3 to rotate relative to each other without affecting each other. The rotating plate 31 and the sliding plate 32 are linked by the mutual engagement of the sliding column 312 at one end of the guide rod 311 and the column groove 321. This allows the relative length of the combined rotating plate 31 and sliding plate 32 to be adjusted within a certain range by pulling. The internal structure is modified, and the relative position of the threaded post 323 at one end of the slide plate 32 is changed in coordination with the rotation of the rotating plate 31, so as to adapt to the change of the size of the inverter body 4 within a certain range and ensure the clamping function of the fixing component 3 on the inverter body 4. The supporting circular plate 322 and the central circular plate 21 are in contact with the wall surface of the inverter body 4. The elastic contraction rod 5, which is fixed to the side wall of the wall-mounted base plate 1 by the bracket, provides elastic contraction force to the L-shaped limiting plate 51. After the fixing component 3 clamps and limits the inverter body 4, one end of the L-shaped limiting plate 51 can prevent the overall deflection of the inverter body 4 after the fixing component 3 is fixed on it by contacting the bottom surface of the inverter body 4. The mutual engagement between the limiting slider 11 and the limiting slot 52 of the wall-mounted base plate 1 increases the structural stability of its reciprocating motion without hindering its contraction movement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
