[0001] The invention relates to power distribution cabinet technology, in particular to a power distribution cabinet for building electrical appliances. Background Art

[0002] In building electrical systems, distribution cabinets play a key role in distributing and controlling electrical energy.

[0003] Existing building electrical distribution cabinets are mainly composed of a base and an integrated cover. When installing and repairing electrical components, they can only be handled through the operation port. However, the distribution cabinet in a long-term operation state has many internal electrical components and circuits, and is prone to some faults. When a fault occurs and needs to be repaired, the operator cannot enter the distribution cabinet to troubleshoot the fault point or repair the fault in the deep of the distribution cabinet or on the back of the electrical component, which makes the distribution cabinet have certain limitations in actual application. Summary of the invention

[0016] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] Embodiment 1: See also Figure 1-Figure 3 A distribution cabinet for building electrical appliances, comprising a base 1, the top of the base 1 is rectangular and symmetrically mounted with four right-angle plates 101, the top of the right-angle plates 101 is mounted with the same top plate 102, four vertical plates 103 are mounted between the base 1 and the top plate 102, the four vertical plates 103 are connected in pairs in sequence to form a rectangular cover, one of the vertical plates 103 is provided with an operation port 104, the operation port 104 is provided with an operation door 105, and the right-angle plate 101 is provided with an electrical component mounting frame 106; A connecting plate 2 is provided at each of the four corners of the top of the base 1, a hinged plate 21 is hingedly connected to one side of the vertical plate 103 close to the connecting plate 2, and a connecting piece is provided between the hinged plate 21 and the connecting plate 2, and the connecting piece is used to connect and fix the hinged plate 21 and the connecting plate 2; A limiting member is provided between the connecting plate 2 and the base 1 , and the limiting member is used to connect and fix the connecting plate 2 and the base 1 .

[0018] In this embodiment, the connecting member includes an assembly groove 3 opened on the surface of the connecting plate 2, and an adapter portion 31 matched with the assembly groove 3 is arranged on the hinged plate 21. An entry groove 32 is opened on the surface of the assembly groove 3, and an extension card groove 33 is opened at the top and bottom of the entry groove 32. A limiting guide groove 34 is opened on the surface of the adapter portion 31, and an embedding strip 35 is symmetrically slidably connected to the upper and lower ends of the inner side surface of the limiting guide groove 34. The two embedding strips 35 are each provided with a limiting card strip 36 at one end away from each other. The adapter portion 31 is slidably connected to a push block 37 fixedly connected to the embedding strip 35 on the side away from the embedding strip 35, and a connecting spring 38 is fixedly connected between the two embedding strips 35.

[0019] It should be noted that the shape and size of the entry groove 32 are compatible with the embedding strip 35 and the limiting strip 36, and the shape and size of the extension slot 33 are compatible with the limiting strip 36, so that during the rotation of the vertical plate 103, the embedding strip 35 and the limiting strip 36 can enter the entry groove 32 synchronously, and after the limiting strip 36 enters the entry groove 32, it can slide along the inner side surface of the entry groove 32 into the extension slot 33, so that the vertical plate 103 can be connected and fixed to the connecting plate 2.

[0020] In this embodiment, the limiting member includes a vertical guide groove 4 opened inside the connecting plate 2, a limiting groove 41 corresponding to the vertical guide groove 4 is opened on the top surface of the base 1, a limiting rod 42 is slidably connected to the inner side surface of the vertical guide groove 4, a return spring 43 is fixedly connected between the top of the limiting rod 42 and the inner wall of the vertical guide groove 4, and a push plate 44 fixedly connected to the limiting rod 42 is slidably connected to the surface of the connecting plate 2.

[0021] It should be noted that the shape and size specifications of the limiting groove 41 are compatible with the limiting rod 42, so that the limiting rod 42 can be inserted into the limiting groove 41 during the downward movement along the vertical guide groove 4, thereby connecting and fixing the connecting plate 2 to the base 1 so that the relative position between the connecting plate 2 and the base 1 cannot move.

[0022] There are two maintenance states during the maintenance of the power distribution cabinet: The first state: the board is turned on for maintenance: When it is necessary to inspect the inside of the power distribution cabinet, the operator manually pushes the side push block 37 on the vertical plate 103 that matches the position to be inspected, and the push block 37 moves to drive the embedded strip 35 and the limiting card strip 36 to move, so that the limiting card strip 36 moves out of the extended card slot 33. At this time, the operator rotates the vertical plate 103 to drive the side hinge plate 21 to rotate and separate from the connecting plate 2, so that the side vertical plate 103 rotates and separates from the base 1 and the rectangular cover formed by the vertical plate 103 is opened on one side, which is convenient for the inspector to inspect; The second state: Multiple boards are turned on for maintenance: On the basis of the above-mentioned single-board maintenance state, the operator pushes the push plate 44 on the connecting plate 2 connected to the vertical plate 103 in the non-fixed state, and the movement of the push plate 44 drives the limiting rod 42 to move upward, so that the bottom end of the limiting rod 42 withdraws from the inside of the limiting groove 41, so that the connecting plate 2 can rotate relative to the base 1. At this time, the operator continues to push the vertical plate 103 in the non-fixed state, so that the vertical plate 103 and the other side vertical plate 103 connected to the connecting plate 2 can rotate, so that the rectangular cover assembled by the vertical plates 103 can be opened synchronously on multiple sides, so that the operator's maintenance space is larger, which is convenient for maintenance work.

[0023] Embodiment 2: See also Figure 1-Figure 3 This embodiment provides a technical solution based on the above embodiment: the top of the base 1 is fixedly connected with positioning bars 5 corresponding to the four vertical plates 103 respectively.

[0024] It should be noted that when the four vertical plates 103 and the connecting plate 2 are assembled and matched to form a complete rectangular cover, the vertical plates 103 abut against the positioning blocking strips 5 .

[0025] After the inspection is completed, the end of the rotation stroke of the vertical plate 103 is limited by the positioning stop bar 5, so that the vertical plate 103 cannot continue to rotate after rotating to abut against the positioning stop bar 5, thereby facilitating the rapid positioning of the vertical plate 103 during assembly, making the assembly of the distribution cabinet more convenient.

[0026] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
