Description

Technical Field

[0001] This utility model belongs to the field of inverter installation technology, specifically relating to an inverter that is easy to install. Background Technology

[0002] An inverter is a power conversion device that converts direct current (DC) to alternating current (AC). It is mainly used in solar power generation systems, wind power generation systems, electric vehicles, and other fields. Inverters are usually composed of multi-stage circuit topologies to improve their efficiency, stability, and reliability. Common inverter topologies include single-phase bridge inverters, three-phase bridge inverters, and multi-stage inverters. Depending on the application scenario, inverters also have various application forms and types, such as series inverters, parallel inverters, photovoltaic inverters, and vehicle-mounted inverters.

[0003] Most existing inverters are connected and fixed with bolts. To ensure the stability of the inverter installation, multiple bolts are required during the fixing process. After long-term use, some bolts may age and rust due to contact with air, making it impossible to disassemble, repair or replace the inverter, which is inconvenient for users. Utility Model Content

[0004] The purpose of this invention is to provide an inverter with a simple structure, reasonable design, and convenient installation in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An inverter that is easy to install includes an inverter body and a mounting base fixedly mounted on an external support structure. Two rubber tubes are symmetrically arranged on the back of the inverter body. Both rubber tubes are fixedly connected to the outer wall of the inverter body. The mounting base has a slot on the side near the inverter body that is aligned with the rubber tubes. The rubber tubes are slidably connected in the slots. An expansion structure for compressing and expanding the rubber tubes is also inserted into the inner cavity of the rubber tubes.

[0007] As a further optimization of this utility model, the inverter body has a wiring socket at its end that is electrically connected to the inverter body, and a heat dissipation hole is provided on the outer wall of the inverter body near the mounting base.

[0008] As a further optimization of this utility model, a set of ear plates is fixedly connected to both sides of the mounting base. The two ear plates in each set are symmetrically arranged. The ear plates are provided with mounting holes, and expansion bolts are inserted into the mounting holes. The expansion bolts pass through the mounting holes and through the ear plates to be fixed to the external support structure.

[0009] As a further optimization of this utility model, the slot has an arc-shaped structure, the inner diameter of the slot is equal to the outer diameter of the rubber tube, and the width of the slot opening is smaller than the diameter of the tensioning structure.

[0010] As a further optimization of this utility model, the tensioning structure includes a rod inserted into one end of the rubber tube and a tube inserted into the other end of the rubber tube. The rod has an integrally formed extrusion head at one end inside the rubber tube, and the tube has an expansion slit on the side wall at one end inside the rubber tube.

[0011] As a further optimization of this utility model, a handle is integrally formed on the ends of the insertion rod and the insertion tube that are far apart from each other. The diameter of the handle is larger than the outer diameter of the rubber tube, and anti-slip texture is formed on the periphery of the handle.

[0012] As a further optimization of this utility model, a heat dissipation groove is provided on the mounting base between the two slots, and a plurality of U-shaped heat dissipation fins are linearly arranged in the heat dissipation groove. The heat dissipation fins abut against the side wall of the inverter body where the heat dissipation hole is provided.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The inverter body is secured to the mounting base by a rubber tube and the tensioning action of the plug and rod. This ensures relative fixation between the inverter body and the mounting base, making installation convenient. Furthermore, the rubber tube covers the plug and rod after they are inserted into the rubber tube, preventing air from entering and causing corrosion due to moisture. This prevents the plug and rod from becoming difficult to remove due to exposure to air, which would otherwise make the inverter body difficult to disassemble for maintenance and replacement.

[0015] 2. The inverter body has heat dissipation holes on the side near the mounting base. The mounting base has heat dissipation slots that are aligned with the heat dissipation holes. The heat dissipation slots can suspend the heat dissipation holes, and multiple heat sinks linearly arranged in the heat dissipation slots can accelerate heat exchange. This can achieve rapid heat dissipation on the side of the inverter body that is in contact with the mounting base, thus avoiding the problem of poor heat dissipation performance on the side of the inverter body that affects the service life of the inverter body.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1 - Figure 4 As shown, an inverter that is easy to install includes an inverter body 1 and a mounting base 5 fixedly installed on an external support structure. A set of ear plates 6 are fixedly connected to both sides of the mounting base 5. The two ear plates 6 in each set are symmetrically arranged. The ear plates 6 are provided with mounting holes. Expansion bolts 7 are inserted into the mounting holes. The expansion bolts 7 pass through the mounting holes and through the ear plates 6 and are fixed to the external support structure, thereby realizing the fixation between the mounting base 5 and the external support structure.

[0024] The inverter body 1 has a wiring socket 2 at one end that is electrically connected to the inverter body 1, so that the user can insert the plug into the wiring socket 2 and use the inverter body 1 to perform power conversion. The inverter body 1 has a heat dissipation hole 3 on the outer wall of the side near the mounting base 5 for heat dissipation when the inverter body 1 is working.

[0025] Two rubber tubes 4 are symmetrically arranged on the back of the inverter body 1. Both rubber tubes 4 are fixedly connected to the outer wall of the inverter body 1. The mounting base 5 has a slot 9 on the side close to the inverter body 1 that is aligned with the rubber tube 4. The slot 9 has an arc-shaped structure and the inner diameter of the slot 9 is equal to the outer diameter of the rubber tube 4. The rubber tube 4 is slidably connected in the slot 9. A tensioning structure for squeezing and expanding the rubber tube 4 is also inserted in the inner cavity of the rubber tube 4.

[0026] The tensioning structure includes a rod 10 inserted into one end of the rubber tube 4 and a tube 11 inserted into the other end of the rubber tube 4. The rod 10 has an integrally formed extrusion head 12 at one end inside the rubber tube 4, and the tube 11 has an expansion slit 13 on the side wall at one end inside the rubber tube 4. When the rod 10 and the tube 11 are inserted from both ends of the rubber tube 4, they can be squeezed against each other. The extrusion head 12 is inserted into the tube 11. Since the diameter of the extrusion head 12 is slightly larger than the inner diameter of the tube 11, after the extrusion head 12 is inserted into the end of the tube 11 inside the rubber tube 4, it can squeeze the end of the tube 11 to expand along the expansion slit 13 and squeeze the outer rubber tube 4 to deform. With the limiting effect of the inner wall of the slot 9, the rubber tube 4 is clamped and fixed in the slot 9.

[0027] Both the plug rod 10 and the plug tube 11 have an integrally formed handle 14 at their opposite ends. The diameter of the handle 14 is larger than the outer diameter of the rubber tube 4. When it is necessary to disassemble the inverter body 1 for maintenance, the plug rod 10 and the plug tube 11 can be pulled in the opposite direction by the handle 14 to pull them out of the rubber tube 4, thus enabling the disassembly of the inverter body 1.

[0028] The handle 14 has anti-slip textures around its perimeter. These textures increase the friction between the user's fingers and the handle 14, minimizing slippage when installing or removing the tensioning structure and making it more convenient for the user.

[0029] A heat dissipation groove 8 is provided on the mounting base 5 between the two slots 9. Multiple U-shaped heat dissipation fins 15 are linearly arranged in the heat dissipation groove 8. The heat dissipation fins 15 abut against the side wall of the inverter body 1 where the heat dissipation hole 3 is provided. The setting of the heat dissipation groove 8 can make the side of the inverter body 1 that is in contact with the mounting base 5 suspended. With the setting of the heat dissipation fins 15 and the heat dissipation hole 3, it is more conducive to heat dissipation on the side of the inverter body 1 that is in contact with the mounting base 5, which can greatly improve the service life of the inverter body 1.

[0030] It should be noted that this type of easy-to-install inverter, during installation, firstly, the mounting base 5 is fixed to the external support using the ear plate 6 and expansion bolts 7. Then, the rubber tube 4 connected to the inverter body 1 is aligned with the slot 9, and the rubber tube 4 is pressed into the slot 9. The deformation of the rubber tube 4 itself presses it into the slot 9. Then, the user inserts the plug rod 10 and the plug tube 11 from both ends of the rubber tube 4 respectively, and presses the plug tube 11 and the plug rod 10 towards each other. The pressing head 12 is then inserted into the plug tube 11. Since the diameter of the pressing head 12 is slightly larger than the inner diameter of the plug tube 11, the pressing head 12 is inserted into the plug tube 11. After the extrusion head 12 is inserted into one end of the insertion tube 11 located inside the rubber tube 4, it can squeeze the end of the insertion tube 11 to expand along the expansion joint 13, and squeeze the rubber tube 4 from the inside to deform outward. With the limiting effect of the inner wall of the slot 9, the rubber tube 4 is clamped and fixed in the slot 9, and the installation of the inverter body 1 can be completed. Not only is the installation convenient, but after the insertion tube 11 and the insertion rod 10 are inserted into the rubber tube 4, the rubber tube 4 can cover them to isolate them from the air, preventing the insertion tube 11 and the insertion rod 10 from rusting and becoming unable to be pulled out, which would make it difficult to disassemble the inverter body 1 for maintenance and replacement.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
