[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] like Figures 1 to 8 The electrical box shown includes: a shell 1, wherein the shell 1 includes a shell plate, and the shell plate is provided with an opening 12; a mounting plate 2, wherein the mounting plate 2 is movably provided in the shell 1, and one end of the mounting plate 2 is rotatably provided on the shell plate; a limiting structure, wherein the limiting structure is provided in the shell 1, and the mounting plate 2 has a self-supporting state of being clamped between the shell plate and the limiting structure. When installing electronic components, the electronic components are placed on the mounting plate 2, and then the mounting plate 2 is placed into the interior of the shell 1 through the opening 12. When the mounting plate 2 is not fixed on the shell 1, the mounting plate 2 is clamped by the limiting structure and the bottom plate of the shell 1 to achieve self-support of the mounting plate 2, thereby effectively overcoming the problem in the prior art that the operator needs to hold the electronic components and related plastic parts and perform single-handed operation, effectively reducing the workload of the operator, and shortening the time of working at heights, thereby reducing the complexity of disassembly and assembly and improving the efficiency of disassembly and assembly.

[0044] The housing 1 includes a base plate 11, an opening 12 is provided on the base plate 11, and the lower end of the mounting plate 2 is rotatably provided on the base plate 11. When the mounting plate 2 is in a self-supporting state, the mounting plate 2 is clamped between the base plate 11 and the limiting structure. After the mounting plate 2 is placed in the housing 1, the lower end of the mounting plate 2 abuts against the base plate 11. At this time, because the mounting plate 2 is not fixed to the housing 1, the mounting plate 2 will tilt downward under the action of gravity and the pull of the wiring of the electronic components on the mounting plate 2. When the mounting plate 2 tilts to a certain angle, its upper end will be clamped and fixed by the limiting structure, thereby preventing the mounting plate 2 from moving further and achieving a self-supporting effect. In other words, at this time, the mounting plate 2 remains relatively stationary under the fixation of the base plate 11 and the limiting structure, and the operator does not need to support the mounting plate 2, so that the operator can perform other disassembly and assembly operations with both hands, thereby improving disassembly and assembly efficiency.

[0045] Specifically, the housing 1 includes a first side panel 13 and a top panel 14. The top panel 14 is connected to the first side panel 13. As the distance from the top panel 14 to the bottom panel 11 decreases in the direction away from the first side panel 13, the top panel 14 forms the limiting structure. That is, the top panel 14 is tilted at this time, and part of the top panel 14 is within the movement trajectory of the upper end of the mounting plate 2 during the tilting process. Therefore, during the tilting and flipping process of the mounting plate 2, the upper end can abut against the top panel 14 and be restricted from moving, thereby achieving self-support of the mounting plate 2. Figure 7 As shown, a protrusion is provided on the upper end of the mounting plate 2 , and the protrusion is used to achieve abutment and fit between the mounting plate 2 and the top plate 14 .

[0046] Optionally, an angle α is formed between the top plate 14 and the first side plate 13 , and 0°≤α<90°. Preferably, the vertex of the angle α is located at the connection position between the top plate 14 and the first side plate 13 .

[0047] The bottom plate 11 includes a support plate 15. The edge of the support plate 15 away from the first side plate 13 constitutes a portion of the edge of the opening 12. In the self-supporting state, the lower end of the mounting plate 2 abuts against the support plate 15. When the mounting plate 2 is placed into the housing 1 through the opening 12, the lower end of the mounting plate 2 is pushed, so that the lower end of the mounting plate 2 moves above the support plate 15, thereby supporting the lower end of the mounting plate 2.

[0048] In one embodiment, the lower end of the mounting plate 2 is provided with a mating groove, within which the support plate 15 is disposed. The mating groove comprises an upper sidewall 31 and a lower sidewall 32, with the upper sidewall 31 positioned above the lower sidewall 32. In the self-supporting state, the support plate 15 abuts against the upper sidewall 31. In this state, the lower sidewall 32 is positioned outside the housing 1, allowing the mounting plate 2 to move simply by applying a force to the lower sidewall 32 from the outside. Furthermore, the support plate 15 positioned within the mating groove restricts the movement of the mounting plate 2, preventing the lower end of the mounting plate 2 from breaking free from the restraints of the housing 1 and causing it to fall.

[0049] The relationship between the width Y of the upper side wall 31 and the angle α is:

[0050] Y=X(1 / tanα);

[0051] Wherein, X is the length of the mounting plate 2 .

[0052] The relationship between the width Y1 of the lower side wall 32 and the angle α is:

[0053] Y1=X(cosα / sin2α);

[0054] Wherein, X is the length of the mounting plate 2 .

[0055] The relationship between the distance Z between the upper side wall 31 and the lower side wall 32 of the matching groove and the angle α is:

[0056] Z=X[(tan2α+1-sinαtan2α) / sinαtan2α];

[0057] Wherein, X is the length of the mounting plate 2 .

[0058] Furthermore, the electrical box also includes a box cover 4, which is arranged at the opening 12. The mounting plate 2 has a fixed state fixed to the housing 1. When the mounting plate 2 is in the fixed state, the lower side wall 32 is located between the box cover 4 and the bottom plate 11. The box cover 4 is used to close and open the opening 12 to achieve the closure of the electrical box, while shielding the lower side wall 32, thereby increasing the aesthetics of the electrical box. When the mounting plate 2 is in the fixed state, the mounting plate 2 is attached to the first side plate 13 and fixed with bolts or the like. When the mounting plate 2 switches from the self-supporting state to the fixed state, the mounting plate 2 is first attached to the first side plate 13, and then the mounting plate 2 is slid upward to move the mounting plate 2 to the set position, and then fixed with bolts.

[0059] The lower side wall 32 is fixed to the box body 4 by bolts.

[0060] Optionally, a mounting hole 16 is provided on the first side panel 13, and a connecting piece is provided on the box cover 4, and the connecting piece is rotatably connected to the mounting hole 16. When the box cover 4 is opened, the connecting piece can be used to hang the box cover 4 on the housing 1, thereby reducing the disassembly and assembly operations of the box cover 4 and further improving the disassembly and assembly efficiency.

[0061] The edge of the box lid 4 is bent to form a bent structure, which constitutes the connecting member. Specifically, the bent structure includes a first bent section 51 and a second bent section 52 that are connected to each other. The first bent section 51 is connected to the box lid 4. The connection between the first bent section 51 and the second bent section 52 is located at the mounting hole 16. When the box lid 4 closes the opening 12, the second bent section 52 extends into the mating groove. The first bent section 51 avoids the distance between the mounting hole 16 and the base plate 11, ensuring that the box lid 4 can be reliably closed at the opening 12, while the second bent section 52 can extend into the mounting hole 16 to achieve the suspension of the box lid 4.

[0062] As another embodiment, the housing 1 includes a first side panel 13 and a top panel 14, wherein the top panel 14 is connected to the first side panel 13 and is provided with an assembly groove. The mounting plate 2 is fixed to the housing 1. When the mounting plate 2 is in the fixed state, a portion of the mounting plate 2 is located within the assembly groove. After the mounting plate 2 is placed into the housing 1, it is necessary to fit the mounting plate 2 onto the first side panel 13, then move the mounting plate 2 upward to a set position, and then secure it with bolts. As the mounting plate 2 moves upward, the upper end of the mounting plate 2 gradually penetrates into the assembly groove, and the assembly groove is used to limit the degree of freedom of the mounting plate 2, thereby achieving the fixation of the mounting plate 2.

[0063] Specifically, the minimum distance between the support plate 15 and the top plate 14 is less than or equal to the length of the mounting plate 2. When the mounting plate 2 is in a self-supporting state, the mounting plate 2 cannot escape from the support plate 15 and the top plate 14 due to size restrictions, thereby preventing the mounting plate 2 from falling.

[0064] The distance between the connection between the first side panel 13 and the top panel 14 and the mounting hole 16 is greater than or equal to the length of the mounting plate 2. This ensures that the mounting plate 2 is securely fixed to the first side panel 13 and that the second bent section 52, which protrudes from the mounting hole 16 into the first side panel 13, fits within the mating groove. If the distance between the connection and the mounting hole 16 is too small, the mounting plate 2 will not fit properly. If the distance between the connection and the mounting hole 16 is too large, the electrical box will be too large, increasing the space occupied.

[0065] The support plate 15 is connected to the lower edge of the first side plate 13, and the distance between the mounting hole 16 and the support plate 15 is less than or equal to the distance between the upper side wall 31 and the lower side wall 32, so that when the mounting plate 2 moves up and down, the upper side wall 31 and the lower side wall 32 will not interfere with the support plate 15, thereby ensuring that the mounting plate 2 can be moved to the set position for fixation.

[0066] The support plate 15 is connected to the lower edge of the first side plate 13. The distance between the connection between the first side plate 13 and the top plate 14 and the support plate 15 is equal to the sum of the length of the mounting plate 2 and the distance between the upper side wall 31 and the lower side wall 32. This allows the upper end of the mounting plate 2 to abut the connection between the first side plate 13 and the top plate 14, thereby securing the upper end of the mounting plate 2.

[0067] The width of the first bent section 51 is less than or equal to the distance between the upper side wall 31 and the lower side wall 32. This allows the box cover 4 to fit snugly against the lower side wall 32 when closing the opening 12, thus preventing damage to the mounting plate 2 or electronic components due to vibration during transportation.

[0068] The width of the second bent section 52 is less than or equal to the width of the support plate 15. In particular, the width of the second bent section 52 is less than or equal to the distance between the upper side wall 31 and the lower side wall 32. This prevents structural interference between the second bent section 52 and the mating groove, ensuring that the second bent section 52 can extend into the mating groove when the mounting plate 2 is fixed to the first side plate 13.

[0069] A rooftop machine includes the above-mentioned electrical box.

[0070] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
