Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to a hinge mechanism for a large-angle distribution box. Background Technology

[0002] A distribution box is a core electrical device in a building or electrical installation site, used to centrally install switching equipment, measuring instruments, protective electrical appliances (such as circuit breakers and fuses), and auxiliary equipment, and to distribute electrical energy. It is the first centralized point after electricity enters the building (from the power grid or generator). It safely and orderly distributes the main incoming power to various branch circuits, supplying power to different areas (such as rooms or floors) or different electrical equipment (such as lighting, sockets, air conditioners, kitchen appliances, etc.). The switches (mainly circuit breakers) installed inside the box can easily connect or disconnect the various branch circuits, facilitating daily operations (such as cutting off power during maintenance or renovation) and fault isolation.

[0003] Existing distribution boxes typically have a small opening angle, usually around 90 degrees. This angle obstructs the space inside the box near the hinge, making it difficult for electricians to easily reach their hands and tools (such as screwdrivers, pliers, and multimeter probes) to perform tasks (like tightening screws, wiring, and taking measurements). This is especially problematic when the box is deep or the equipment is densely packed, making operation very awkward. Furthermore, the door obstructs the view, making it difficult to observe the status, labels, and wiring of the equipment inside (especially near the hinge), potentially requiring constant head adjustments or the use of lighting.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0005] The present invention provides a hinge mechanism for a large-angle distribution box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hinge mechanism for a large-angle distribution box includes a front frame of the box, a hinge mechanism, and a door. The front frame of the box has a door opening, and the edge of the door opening is recessed with a groove. One side of the groove has an inner groove. The hinge mechanism includes a first hinge and a second hinge that are hinged to each other. The first hinge includes a first mounting part, and the top and bottom of the first mounting part both extend to one side to form a first hinge portion. The second hinge includes a second mounting part, a U-shaped part, and a second hinge portion. The second hinge portion is disposed within the first hinge portion. A pivot is provided through the first hinge portion and the second hinge portion. The second mounting part is connected to one side of the door.

[0008] Preferably, the first end of the U-shaped portion is connected to one side of the second hinge portion, and the second end of the U-shaped portion is connected to one side of the second mounting portion.

[0009] Preferably, both the first mounting part and the second mounting part are provided with bolts. The first mounting part is located on the rear side of the door opening and is fixed by bolts. The U-shaped part is located in the inner groove. Beneficial effects

[0010] This invention solves the technical bottleneck of limited opening angle of traditional distribution box doors through collaborative innovation of hinge geometry reconstruction and embedded door design. The specific benefits are as follows:

[0011] This utility model features a U-shaped section that, when the door is closed, conceals the hinge protrusion by embedding the U-shaped section into an inner groove, and releases movement space when open, achieving a flat appearance and compatibility with full-angle opening and closing. The hinge mechanism allows for a larger opening and closing angle of the door, which has significant advantages in terms of operation and maintenance, safety, and space adaptability compared to designs with a smaller opening and closing angle. Furthermore, in the closed state, the edge of the door is tightly embedded in the groove, forming a labyrinthine sealing interface, which enhances the sealing effect and strength between the door and the front frame of the cabinet.

[0020] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0021] like Figure 1-3 As shown, it is a structural schematic diagram of a large-angle distribution box hinge mechanism according to a preferred embodiment of the present invention.

[0022] In this embodiment, the enclosure includes a front frame 1, a hinge mechanism 2, and a door 3. At least two hinge mechanisms 2 are provided. The front frame of the enclosure 1 has a door opening 4. The edge of the door opening 4 is recessed with a groove 5. In the closed state, the edge of the door 3 is tightly embedded in the groove 5, forming a labyrinthine sealing interface. This provides a flush sealing surface when the door 3 is closed, reducing wind resistance and dust intrusion, and enhancing the sealing effect and strength between the door 3 and the front frame 1. At least two inner grooves 6 are provided on one side of the groove 5, located at the top and bottom of the groove 5 respectively. The inner grooves 6 provide rotational clearance space for the U-shaped part 12. The hinge mechanism 2 includes a first hinge 7 and a second hinge 8 that are hinged to each other. The first hinge 7 includes a first mounting part 9, and the top and bottom of the first mounting part 9 both extend to one side to provide a first hinge part 10. Through the double support point design at the top and bottom, a stable rotation axis is provided. The second hinge 8 includes a second mounting part 11, a U-shaped part 12, and a second hinge part 13. The U-shaped part decomposes the rotational motion of the door 3 into a composite motion of "rotation + translation", breaking through geometric limitations. The second hinge part 13 is located inside the first hinge part 10. A rotating shaft 14 passes through the first hinge part 10 and the second hinge part 13. The second hinge part 13 is nested inside the first hinge part 9, and relative rotation is achieved through the rotating shaft 14. The second mounting part 11 is connected to one side of the door 3.

[0023] In this embodiment, the first end of the U-shaped part 12 is connected to one side of the second hinge part 13, and the second end of the U-shaped part 12 is connected to one side of the second mounting part 11. This structure realizes a spatial bending structure, which moves the rotation center towards the inside of the box.

[0024] In this embodiment, both the first mounting part 9 and the second mounting part 11 are provided with bolts 15. The first mounting part 9 is located on the rear side of the door opening 4 and is fixed by bolts 15. The U-shaped part 12 is located in the inner groove 6. When the door 3 is opened, the second hinge 8 rotates around the pivot 14, and the U-shaped part 12 begins to disengage from the inner groove 6. The door 3 swings outward, and the U-shaped part 12 completely exits the inner groove 6, eliminating interference with the edge of the front frame 1 of the box body. Under the guidance of the U-shaped part 12, the movement trajectory of the door 3 changes from radial rotation to axial translation.

[0025] The hinge mechanism of the large-angle distribution box of this utility model has common mechanical methods in terms of installation, connection or setting. It can be implemented as long as it can achieve its beneficial effect.

[0026] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0027] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
