Description

Technical Field

[0001] The utility model relates to the technical field of frequency converters, in particular to a silent frequency conversion housing installation and fixing structure. Background Art

[0002] With the continuous improvement of industrial automation level, the application scope of frequency converter as a common industrial control component is becoming increasingly wide. In order to meet the needs of different usage environments, frequency converters usually need to be equipped with a casing to achieve functions such as dustproof, moisture-proof, and noise reduction.

[0003] The conventional inverter housing adopts a common fixing method, which is mainly to provide screw holes on each mounting surface and use screws to fix the housing components to the device body or the mounting base.

[0004] However, in the prior art, the fixing structure fails to efficiently meet the requirements of quick installation and disassembly to a large extent. Each mounting surface usually requires a separate screw fixation, so more mounting positions are designed on the inverter housing, which not only increases the processing cost of the housing, but also increases the complexity of manufacturing and installation. Especially during on-site installation or maintenance, too many screw fixing points increase the difficulty of operation for staff and extend the installation or maintenance time. In addition, repeated tightening and loosening of the screws can easily cause thread wear, affecting the reliability of fixation.

[0005] Therefore, those skilled in the art have proposed a silent frequency conversion housing installation and fixing structure. Utility Model Content

[0006] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a silent frequency conversion housing installation and fixing structure.

[0007] The technical solution of the utility model is as follows: the silent variable frequency housing installation and fixing structure is mainly composed of two main housings and multiple connecting parts to ensure the stability of the structure and easy installation. There are two main components in the structure, namely the first housing and the second housing, which are connected by a connecting rod to ensure the overall stability and integrity of the structure.

[0008] Inside the first housing, there are six symmetrically arranged connection plates: a first connection plate, a second connection plate and a third connection plate. These plates are symmetrically arranged, and each connection plate is preset with a fixing hole for convenient fixing.

[0009] In the second housing, six first connection holes and two second connection holes are designed, and the height of the second connection holes is set lower than that of the first connection holes. This may be to adapt to different installation height requirements or the layout of internal components.

[0010] The connecting rod is not only used to connect the two shells, but also has several mounting holes symmetrically arranged on its outer side: a first mounting hole, a second mounting hole and six third mounting holes. The corresponding positions of these mounting holes correspond to the connecting plate or the connecting holes, so that a firm connection can be achieved by screws.

[0011] During assembly, the first connecting plate can be engaged with the first first mounting hole on the first shell and fixed with screws; the second connecting plate will be aligned with a first connecting hole on the second shell and correspond to the first first mounting hole, and then also fixed with screws; the third connecting plate corresponds to a third mounting hole and is also fixed with screws.

[0012] Finally, the second connection hole is aligned with the second mounting hole and fixed, and the first connection hole is aligned with a third mounting hole, and both are fixed by screws. Through such a design, the mounting structure ensures a tight connection between the shells, and also achieves a silent effect, which is suitable for environments with high noise requirements.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] In the utility model, the first shell and the second shell can be directly fixed on the connecting rod, and the second connecting plate overlaps with the first connecting hole of the first shell and overlaps with the first mounting hole of the connecting rod, thereby increasing the stability of the structure. This design simplifies the installation process, and only one screw is needed at each corresponding position to complete the fixation of the first shell and the second shell. This not only saves materials, but also reduces installation time, improves the efficiency of installation and disassembly, and greatly improves the operation quality and use efficiency compared with traditional devices.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1-Figure 5 As shown, the utility model provides a silent variable frequency housing installation and fixing structure: comprising a first housing 1, a second housing 2 and a connecting rod 3, wherein the first housing 1 and the second housing 2 are connected by the connecting rod 3, and inside the first housing 1, a first connecting plate 101, a second connecting plate 102 and a third connecting plate 103 are arranged in a symmetrical order, and each connecting plate is provided with a fixing hole for screw fixing inside, and inside the second housing 2, six first connecting holes 201 and two second connecting holes 202 are symmetrically arranged in sequence, wherein the second connecting holes 202 are lower in height than the first connecting holes 201. The connecting rod 3 is symmetrically provided with a first mounting hole 301 along its outer side, and a second mounting hole 302 is also provided on one side of the first mounting hole 301, and six third mounting holes 303 are distributed along the connecting rod 3;

[0025] Among them, a first connecting plate 101 is connected and fixed to a corresponding first mounting hole 301 by screws; a second connecting plate 102 coincides with a corresponding first connecting hole 201, and also coincides with a first mounting hole 301, and is fixed by screws; a third connecting plate 103 coincides with a corresponding third mounting hole 303, and is also fixed by screws; a second connecting hole 202 coincides with a second mounting hole 302, and is fixed by screws; finally, a first connecting hole 201 coincides with a third mounting hole 303, and is fixed by screws.

[0026] In summary:

[0027] Through the design of this structure, the first shell 1 and the second shell 2 can be directly fixed on the connecting rod 3. The second connecting plate 102 overlaps with the first connecting hole 201 of the first shell 1 and overlaps with the first mounting hole 301 of the connecting rod 3, thereby increasing the stability of the structure. This design simplifies the installation process. Only one screw is needed at each corresponding position to complete the fixing of the first shell 1 and the second shell 2. This not only saves materials, but also reduces installation time and improves the efficiency of installation and disassembly.
