Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, and in particular relates to a hinge device for fixing a double-layer door panel. Background Technology

[0002] Currently, most electrical control cabinets on the market adopt a frame structure, with their mounting plates covered with visible electrical components. The wiring points of these components are readily apparent. For safety reasons, acrylic panels are commonly used for protection, but they are expensive and have low strength. To overcome these issues, a double-layer metal protective door panel could be designed. However, the hinges available on the market cannot meet the requirements. Therefore, considering cost and ease of processing, it is necessary to research a fixed hinge device for the double-layer door panel. Summary of the Invention

[0003] The technical problem solved by this utility model is achieved through the following technical solution:

[0004] A hinge device for fixing a double-layer door panel includes a hinge, a hinge chain, and a pin.

[0005] The hinge includes a hinge plate, on one side of which a pair of connecting lugs are installed, and a notch is formed between the pair of connecting lugs;

[0006] One side of the hinge forms a pair of connecting pieces, each with a connecting hole; the other end of the hinge forms a pair of mounting pieces, each with a plurality of mounting holes.

[0007] A pair of connecting pieces are located between a pair of connecting lugs, and the connecting lugs are connected to connecting holes on the connecting pieces by a pin, and a cotter pin is installed at the end of the pin, so that the hinge can rotate relative to the hinge within a range of at least 90°.

[0008] Furthermore, the hinge is fixed to the second-layer door panel by a hinge plate, the hinge is fixed to the mounting plate by a mounting piece, and the mounting plate is fixedly connected to the cabinet frame.

[0009] Furthermore, when the second-layer door panel is closed, the hinge rotates along the pin shaft, causing the hinge to drive the second-layer door panel to be parallel to the mounting plate; when the second-layer door panel is open, the hinge rotates along the pin shaft, causing the hinge to drive the second-layer door panel to be perpendicular to the mounting plate.

[0010] Furthermore, the hinge is also provided with weight-reducing holes.

[0011] Furthermore, the hinge has a notch, which can limit the opening angle of the second-layer door panel.

[0012] The advantages and positive effects of this utility model are:

[0013] This utility model realizes the fixing function of a double-layer door panel. The hinge is welded to the double-layer door panel and the hinge is fixed to the mounting plate. Through the cooperation of the hinge and the hinge, the opening and closing function of the double-layer door panel is realized. This design has a simple structure, is easy to install, and has low sheet metal bending and forming processing cost. This hinge device can be used in many fields, especially in the electrical industry. Attached Figure Description

[0022] First, it should be noted that the specific structure, features, and advantages of this utility model will be described in detail below by way of examples. However, all descriptions are for illustrative purposes only and should not be construed as limiting the utility model in any way. Furthermore, any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the accompanying drawings, can still be arbitrarily combined or deleted among these technical features (or their equivalents) to obtain more other embodiments of this utility model that may not be directly mentioned herein. Additionally, for the sake of simplifying the drawings, the same or similar technical features may be indicated only in one place in the same drawing.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0024] Example 1

[0025] like Figure 1-7 As shown, this embodiment provides a hinge device for fixing a two-layer door panel, including a hinge 1, a hinge 2, and a pin 3;

[0026] The hinge 1 includes a hinge plate 101, on one side of which a pair of connecting lugs 102 are installed, and a notch 6 is formed between the pair of connecting lugs;

[0027] One side of the hinge 2 forms a pair of connecting pieces 201, and the connecting pieces are provided with connecting holes. The other end of the hinge forms a pair of mounting pieces 202, and the mounting pieces are provided with a plurality of mounting holes 203.

[0028] like Figure 1 The pair of connecting pieces are located in the notch 6 between the pair of connecting lugs, and the connecting lugs are connected to the connecting holes on the connecting pieces by a pin 3, and a cotter pin 4 is installed at the end of the pin, so that the hinge can rotate within a range of at least 90° relative to the hinge.

[0029] The hinge is fixed to the second-layer door panel via a hinge plate, and the hinge is fixed to the mounting plate via a mounting piece. The mounting plate is fixedly connected to the cabinet frame. When the second-layer door panel is closed, the hinge rotates along the pin shaft, causing the hinge to drive the second-layer door panel to be parallel to the mounting plate. When the second-layer door panel is open, the hinge rotates along the pin shaft, causing the hinge to drive the second-layer door panel to be perpendicular to the mounting plate. The hinge has a notch 5, which can limit the opening angle of the second-layer door panel.

[0030] In addition, to reduce weight, the hinge may also be provided with weight-reducing holes 13.

[0031] Specifically, in this embodiment, such as Figures 1 to 7 As shown, this hinge device inserts the hinge 2 into the middle notch 6 of the hinge 1. The position of the notch of the hinge 1 restricts the up and down movement of the hinge 2, ensuring that the connecting ear hole of the hinge 1 is concentric with the connecting hole on the connecting piece of the hinge 2, which facilitates the insertion of the pin 3, so that the hinge 1 is fixed on the hinge 2. The cotter pin 4 is inserted into the hole of the pin 3, which plays a limiting role on the pin 3.

[0032] Hinge 1 is welded to the second-layer door panel 7. The mounting plate of hinge 2 has several mounting holes 203. Self-tapping screws 12 are used to fix it to the mounting plate 8 through these holes. The mounting plate 8 is firmly connected to the cabinet frame 9. Hinge 1 on the second-layer door 7 is matched with hinge 2 on the mounting plate 8. After inserting the pin 3, the second-layer door 7 is fixed to the mounting plate 8. When the second-layer door panel 7 is closed, only the operating part of the electrical component 11 is exposed. The second-layer door panel 7 protects the electrical component 11. When the outer door panel 10 is closed, it provides double protection for the internal components of the electrical control cabinet. When the second-layer door panel 7 is opened, the door panel rotates around the pin 3. The notch 5 on the hinge 2 limits the opening angle of the second-layer door panel 7.

[0033] The above embodiments have provided a detailed description of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the claims of the present invention should still fall within the patent coverage of the present invention.
