Description

Technical Field

[0001] This utility model relates to the field of quick-release hinges, specifically a quick-release hinge structure for a distribution box door panel. Background Technology

[0002] Distribution cabinets typically have two doors: the outer door is for protection, and the inner door is for isolating live parts to prevent accidental contact and improve electrical safety.

[0003] In existing technology, the inner cabinet door can generally only be rotated open by 90 degrees. When repairing the wiring or replacing components in the distribution cabinet, the 90-degree open inner cabinet door affects the operator's arm reach, resulting in inefficiency during the maintenance or replacement process. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-release hinge structure for the door panel of a power distribution box in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release hinge structure for a distribution box door, including an inner cabinet door installed at the opening of the distribution cabinet, a hinge assembly installed between the back end of the inner cabinet door and the inner wall of the distribution cabinet, the hinge assembly including a fixed hinge and a rotating hinge, the fixed hinge and the rotating hinge being rotatably connected, the fixed hinge being fixedly installed on the inner wall of the distribution cabinet, and the rotating hinge being detachably connected to the inner cabinet door through the quick-release assembly.

[0006] As a further improvement of this utility model: the quick-release assembly includes a protruding ring integrally formed on the back end of the rotating hinge plate, and the protruding ring has a circular hole that extends through to the front end of the rotating hinge plate.

[0007] As a further embodiment of this utility model: the quick-release assembly also includes a rotating shaft rotatably installed in the circular hole, the rotating shaft extending forward to the front end of the inner cabinet door, the front end of the rotating shaft having an outwardly protruding handle integrally formed, and the rear end of the rotating shaft having a limiting plate with a diameter larger than the through hole integrally formed.

[0008] As a further improvement of this utility model: the interior of the inner cabinet door is provided with a through hole for the rotating shaft to pass through, and the outer two ends of the through hole are integrally formed with square grooves with the same cross-section as the handle.

[0009] As a further improvement of this utility model, a rubber damper is installed at the rotatable connection point between the inner wall of the protruding ring and the rotating shaft.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting up a quick-release mechanism, the inner cabinet door and hinge assembly can be separated or connected relatively easily. Therefore, when maintaining the wiring in the distribution cabinet or replacing components, the inner cabinet door can be quickly disassembled to avoid affecting work efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 In this embodiment of the utility model, a quick-release hinge structure for a distribution box door includes an inner cabinet door 1 installed at the opening of the distribution cabinet. A hinge assembly is installed between the back end of the inner cabinet door 1 and the inner wall of the distribution cabinet. The hinge assembly includes a fixed hinge 2 and a rotating hinge 3, which are rotatably connected. The fixed hinge 2 is fixedly installed on the inner wall of the distribution cabinet, and the rotating hinge 3 is detachably connected to the inner cabinet door 1 through the quick-release assembly.

[0019] In this embodiment: First, when it is necessary to inspect or replace the circuits in the distribution cabinet, after the outer cabinet door is opened, the quick-release assembly can be rotated to make the quick-release assembly misaligned with the inner cabinet door 1, and then the inner cabinet door 1 can be removed to facilitate circuit inspection or component replacement. When it is not necessary to remove the inner cabinet door 1, the quick-release assembly is kept connected to the inner cabinet door 1, and there is no need to rotate the quick-release assembly.

[0020] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 The quick-release assembly includes a protruding ring 4 integrally formed on the back end of the rotating hinge 3 plate. The protruding ring 4 has a circular hole that extends through to the front end of the rotating hinge 3 plate. The quick-release assembly also includes a rotating shaft 6 rotatably installed in the circular hole. The rotating shaft 6 extends forward to the front end of the inner cabinet door 1. The front end of the rotating shaft 6 has an integrally formed outwardly protruding handle 7. The rear end of the rotating shaft 6 has an integrally formed limiting plate 5 with a diameter larger than the circular hole. The inner cabinet door 1 has a through hole 8 for the rotating shaft 6 to pass through. The outer two ends of the through hole 8 have integrally formed square grooves with a cross section equal to that of the handle 7.

[0021] In this embodiment: when it is necessary to separate the quick-release component from the inner cabinet door 1, the handle 7 is rotated, and the handle 7 drives the rotating shaft 6 to rotate 90 degrees. At this time, the handle 7 is aligned with the square groove, and the inner cabinet door 1 can be pulled to move. The inner cabinet door 1 can then drive the through hole 8 to slide on the outer periphery of the rotating shaft 6, thereby realizing the disassembly of the inner cabinet door 1.

[0022] After the inspection or replacement is completed, align the square groove on the inner cabinet door 1 with the handle 7, and push the inner cabinet door 1 back to its original position until the through hole 8 is completely locked on the outer circumference of the rotating shaft 6. Then, by rotating the handle 7, the handle 7 and the square groove are misaligned, thus completing the installation of the inner cabinet door 1.

[0023] Please refer to this carefully. Figure 4 A rubber damper is installed at the rotatable connection point between the inner wall of the protruding ring 4 and the rotating shaft 6.

[0024] In this embodiment, the rubber damping design increases the friction between the rotating shaft 6 and the inner wall of the protruding ring 4, thereby ensuring that the handle 7 remains in its current position when no external force is applied to it, thus maintaining the installation stability of the inner cabinet door 1.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
