Description

Technical Field

[0001] This utility model mainly relates to the field of flip-top structure technology, specifically to a flip-top hinge structure for a frequency converter housing. Background Technology

[0002] Currently, frequency converter control boxes are widely used in the control systems of equipment such as water pumps. The box body and cover are typically fixed using four corner screws. While this structure is simple and reliable, meeting basic installation requirements, it presents several inconveniences in actual use, especially during maintenance in wall-mounted installation scenarios.

[0003] First, when the control box needs maintenance or debugging, operators must unscrew all the screws at the four corners of the cover. Because the cover lacks a supporting structure, it is prone to falling off after disassembly, potentially damaging the cover and affecting the internal circuitry. Second, after separating the cover from the box body, the connection between the display board and the main board usually needs to be temporarily disconnected before the cover can be completely removed. This process not only increases operational complexity but may also lead to loose cables or poor contact, affecting equipment stability. Furthermore, the disassembled cover needs to be stored separately, which can easily lead to confusion when maintaining multiple control boxes simultaneously, increasing management difficulty. Currently, some systems use metal hinges for connection, but this method is inconvenient to install, requiring multiple screws to connect the control box to the cover. Replacing the cover is also cumbersome. After frequent opening and closing, the hinge's pivot or connecting parts are prone to wear due to friction, causing the cover to loosen, sag, or produce abnormal noise. If the hinge material has insufficient rust resistance (such as ordinary iron hinges), it may corrode in humid environments, further increasing the risk of structural failure.

Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] See attached document Figure 1-6 A variable frequency drive housing hinged flip cover structure, comprising:

[0040] Control box body 1, wherein a frequency converter device is installed inside the control box body 1;

[0041] The protective cover 2 has two support protrusions 3 on one side. The bottom of the top support protrusion 3 is connected to the first support column 4. The end of the first support column 4 is connected to the elliptical snap-fit ​​block 5. The bottom support protrusion 3 is connected to the second support column 6.

[0042] Two rotating bases 7 are located on the side of the control box body 1. The rotating bases 7 have connecting holes 8, which are matched with the elliptical snap-fit ​​blocks 5.

[0043] In this embodiment, the protective cover 2 is inserted into the connecting hole 8 of the rotating base 7 through the elliptical snap-fit ​​block 5, so that the protective cover 2 can rotate along the rotating base 7. In this way, during maintenance, there is no need to use other tools for cumbersome unlocking work, and the installation efficiency is high, which is convenient for repeated opening and closing operations.

[0044] The bottom of the control box body 1 is provided with a rectangular mounting foot 11, and the mounting foot 11 has a threaded hole 12. The threaded hole 12 is adapted to be connected to a vertical wall with a screw. In this embodiment, the control box body 1 of this application can be installed on the wall with screws.

[0045] The connecting hole 8 has U-shaped grooves 81 with opposite directions on both sides. The open end of the U-shaped groove 81 passes through the rotating base 7. In this embodiment, the U-shaped grooves 81 with opposite directions facilitate casting and one-time casting. Alternatively, to improve installation efficiency, two U-shaped grooves 81 can be set to facilitate quick disassembly of the protective cover 2. During installation, the elliptical locking block 5 is slid into the bottom of the U-shaped groove 81 and then pushed inward so that the locking block is engaged with the rotating base 7. During disassembly, the locking block is aligned with the U-shaped groove 81, lifted upward, and then pulled outward. The specific operation is as follows: When the elliptical locking block 5 needs to be inserted, the elliptical locking block 5 is inserted into the U-shaped groove 81. When it slides into the bottom of the U-shaped groove 81, it can be pushed inward until the elliptical locking block 5 is engaged with the rotating base 7. Then the protective cover 2 can be closed. For the closed state, please refer to Figure 1 The oval-shaped locking block 5 and the connecting hole 8 are arranged in a cross shape, which provides a good locking effect. Please refer to [the instructions] when opening the protective cover 2. Figure 2 The oval-shaped locking block 5 and the connecting hole 8 are arranged in a cross shape, providing a good locking effect and facilitating maintenance. When it is necessary to remove the protective cover 2, refer to... Figure 3 Align the elliptical locking block 5 with the U-shaped groove 81, lift the protective cover 2 upwards so that the elliptical locking block 5 slides into the U-shaped groove 81, and then move the elliptical locking block 5 downwards to the bottom of the U-shaped groove 81, and then pull the protective cover 2 outwards.

[0046] The control box body 1 has first connecting holes 13 at its four corners, and the protective cover 2 has second connecting holes 14 at corresponding positions. The first connecting holes 13 and the second connecting holes 14 are connected by screws. In this embodiment, when the control box is working stably, the first connecting holes 13 and the second connecting holes 14 can be fixedly connected by screws. When the protective cover 2 needs to be opened and closed frequently, the screws can be removed.

[0047] The control box body 1 is provided with a magnetic block 15 at the opening, and the protective cover 2 is provided with a magnetic plate at the corresponding position. In this embodiment, the magnetic block 15 and the magnetic plate work together to temporarily attract the protective cover 2.

[0048] The bottom of the control box body 1 is symmetrically provided with heat dissipation fins 16, and the side of the control box body 1 is provided with cable locking head 17. The cable locking head 17 facilitates the connection of wires to the internal frequency converter, and the heat dissipation fins 16 facilitate the heat dissipation of the internal frequency converter during operation.

[0049] The second support column 6 is connected to an elliptical snap-fit ​​block 5 at its end. Two elliptical snap-fit ​​blocks 5 are provided for better hinge effect and smoother rotation.

[0050] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, 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. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
