[0026] The technical solutions in the embodiments of the utility model will be described below with reference to the drawings in the embodiments of the utility model. Based on the technical solutions in the utility model, all other technical solutions obtained by those skilled in the art without making creative efforts belong to the scope of protection of the utility model.

[0027] Referring to Figures 3-12 , the utility model embodiment provides a kind of electric control box, at least including box 1, circuit breaker 4 and cover plate 6, wherein, box 1 provides the cavity of containing electrical equipment, box 1 is equipped with open part, open part is the part of the communication cavity inside and outside of box 1, circuit breaker 4 is arranged in box 1, cover plate 6 is set with window part 61 on the position corresponding circuit breaker 4, cover plate 6 is covered in the open part of box 1, and at least part of the protruding part of circuit breaker 4 is exposed in window part 61.Electric control box further includes support frame 2 and limiting frame 5.Support frame 2 is set in the bottom of box 1, which is the part of the cavity of box 1 opposite to open part, circuit breaker 4 is installed on support frame 2, limiting frame 5 is equipped with opening, the protruding part of circuit breaker 4 is extended in the opening of limiting frame 5, limiting frame 5 is installed on support frame 2, and the installation position of limiting frame 5 is movable, so that the edge of the protruding part of circuit breaker 4 exposed in window part 61 and the distance of cover plate 6 window part 61 (for example Figure 5distance D2) satisfies a set range s. That is, the distance between the edge of the protruding portion of the circuit breaker 4 exposed to the window portion 61 and the window portion 61 of the cover plate 6 is made to be a value within the set range s. It should be understood that the value within the set range s refers to the gap size between the window portion 61 and the edge of the protruding portion of the circuit breaker 4 exposed to the window portion 61 when the gap can effectively prevent dust and dirt and the like. The set range s can be different ranges of values according to the working environment of the electric control box, that is, the set range s can be set as needed, for example, when the working environment of the electric control box is outdoor, the set range s can be 0mm < s < 2mm, or when the working environment of the electric control box is indoor, the set range s can be 0mm < s < 4mm.

[0028] It is easy to understand that because the installation position of the limiting frame 5 is movable, the protruding portion of the circuit breaker 4 exposed to the window portion 61 is adjusted by moving the limiting frame 5 during the assembly of the electric control box, so that the distance between the edge of the protruding portion of the circuit breaker 4 exposed to the window portion 61 and the window portion 61 of the cover plate 6 satisfies the set range s. In this way, the entry of dust and dirt is avoided, maintenance is convenient, and damage is not easy.

[0029] In some embodiments, the limiting frame 5 at least includes a frame body 51 and a leg 52 fixedly connected with the frame body 51, and the end of the leg 52 away from the frame body 51 is fixedly connected with the support frame 2. The opening portion of the limiting frame 5 is formed by the frame body 51, and when the frame body 51 is sleeved around the protruding portion of the circuit breaker 4, the leg 52 of the limiting frame 5 is located outside the circuit breaker 4, the limiting frame 5 tightly buckles the circuit breaker 4 on the support frame 2 like a cover, and plays a role in enhancing stability. At the same time, the frame body 51 of the limiting frame 5 occupies around the protruding portion of the circuit breaker 4, so that the gap between the edge of the window portion 61 of the cover plate 6 and the protruding portion of the circuit breaker 4 is blocked by the frame body 51, not only improving the waterproof and dustproof capability, but also making the appearance of the front of the electric control box more beautiful. Specifically, the frame body 51 and the leg 52 can form a U-shaped, as shown in Figure 10 Of course, in other embodiments, the frame body 51 and the leg 52 can also form other shapes, for example, a door-shaped.

[0030] As shown in Figure 10 and Figure 11As shown, in some embodiments, the end of the support leg 52 of the limiting frame 5 away from the frame 51 may be provided with a first elongated hole 521 for connecting with the support frame 2. This allows for fine-tuning of the position of the limiting frame 5 when it is installed onto the support frame 2, i.e., adjusting the relative position of the limiting frame 5 and the support frame 2 along the length of the first elongated hole 521. The protruding portion of the circuit breaker 4 includes at least an operating handle 41. Fine-tuning the position of the limiting frame 5 ensures that the operating handle 41 of the circuit breaker 4 does not interfere with the installation of the cover plate 6, thereby achieving precise fit between the circuit breaker 4 and the cover plate 6.

[0031] like Figure 3 and Figure 8 As shown, in some embodiments, the electrical control box may include a mounting rail 3 for installing the circuit breaker 4. The support frame 2 is provided with a second elongated hole 22 for connecting with the mounting rail 3, that is, the mounting rail 3 is installed on the support frame 2 through the second elongated hole 22. When installing the mounting rail 3 onto the support frame 2, the position of the mounting rail 3 can be finely adjusted along the length direction of the second elongated hole 22 to ensure that the circuit breaker 4 can form a good fit with the window portion 61 of the cover plate 6 after being fixedly connected to the support frame 2. When the support leg of the limiting frame 5 is provided with a first elongated hole 521, the length direction of the first elongated hole 521 and the length direction of the second elongated hole 22 can be made perpendicular to each other on a plane parallel to the cover plate 6. The mounting rail 3 can be a conventional model available on the market, such as a C45 guide rail, and this utility model does not limit it in this regard.

[0032] In some embodiments, the support frame 2 and the limiting frame 5 can be sheet metal parts, which are easy to process and manufacture, thus improving the production efficiency of the electrical control box. The shapes of the support frame 2 and the limiting frame 5 can be flexibly set as needed, such as... Figure 10 As shown, in this embodiment, the frame 51 and support legs 52 of the limiting frame 5 form a U-shape, meaning the limiting frame 5 as a whole is U-shaped. This U-shaped structure provides a stable support foundation, making the limiting frame 5 less prone to tipping or deformation under load. The support legs 52 are located on two opposite sides of the frame 51, and the ends of the support legs 52 have outwardly bent edges. The number of support legs 52 can be two or more, for example, in... Figure 11 and Figure 12 In the illustrated embodiment, a support leg 52 is provided at each of the four corners of the frame 51. For example... Figure 7 As shown, in this embodiment, the support frame 2 is configured as a door-shaped structure with an inner folded edge 21. The inner folded edge 21 is the folded edge formed by bending the lower end of the support frame 2 inward. The inner folded edge 21 is connected to the bottom of the box body 1. For example, the inner folded edge 21 can be welded to the bottom of the box body 1, or it can be connected by bolts.

[0033] In some embodiments, the cover plate 6 can be rotatably connected with the box 1 at any edge of the opening, i.e. the edge of the cover plate 6 is rotatably connected with one edge of the opening, for opening and closing the opening, i.e. the cover plate 6 is located at the opening of the box 1 and can be flipped to open and close the opening of the box 1. By introducing the adjustable supporting frame 2 and the L-shaped limiting frame 5 of the circuit breaker 4 and the flipable cover plate 6, the circuit breaker 4 can be quickly adjusted and positioned to adapt to different installation requirements, improve the operation convenience of the circuit breaker 4, and improve the aesthetics and uniformity of the cooperation between the cover plate 6 and the circuit breaker 4. Specifically, the cover plate 6 can be flat, as shown in Figure 6 The operating handle 41 protrudes from the plane where the cover plate 6 is located.

[0034] After the electric control box is put into use, when it is necessary to open the cover plate 6 for maintenance, the cover plate 6 does not need to be detached from the box 1, compared with the traditional electric control box, the operability and maintenance convenience are improved. Moreover, the cover plate 6 is flat, and only the operating handle 41 of the circuit breaker 4 slightly protrudes from the front of the electric control box. The exposed design of the operating handle 41 enables the user to directly contact the handle without additional action when operating, so that the switch operation can be quickly performed, and the operation convenience is improved. Especially in an emergency, such as when it is necessary to quickly cut off the power supply, the exposed handle can be operated more quickly, thereby improving the safety.

[0035] In order to realize the flipping of the cover plate 6 to open and close the opening of the box 1, the rotatable connection structure between the cover plate 6 and the edge of the opening of the box 1 can have multiple choices, for example, a hinge can be installed at the edge of the opening of the box 1 to rotatably connect the cover plate 6 with the box 1, or a shaft seat with a first pin hole can be arranged at the edge of the opening of the box 1, and a connecting part with a second pin hole is arranged at the edge of the cover plate 6, and the cover plate 6 and the box 1 are rotatably connected through a pin shaft arranged in the first pin hole and the second pin hole. It is easy to understand that the axis of the pin shaft is parallel to the plane where the opening of the box 1 is located, so that the cover plate 6 can be rotated to open and close the opening of the box 1, wherein the state of the cover plate 6 when the opening of the box 1 is opened is shown in Figure 3 When the cover plate 6 is in the closed state, the circuit breaker 4 is raised to the required height by the supporting frame 2, and the height of the handle exposed is adjusted by the waist hole on the limiting frame, so as to control the height of the handle exposed. At this time, the L-shaped limiting frame of the limiting frame 5 also provides additional support, so that the cover plate 6 is more stable when closed, and displacement or deformation caused by external force is reduced. When the cover plate 6 is in the open state, the supporting frame 2 and the limiting frame 5 can accurately position the installation position of the circuit breaker 4, so that the circuit breaker 4 can be quickly assembled without adjusting the air gap position or making a tool limiting frame for assembly, thereby improving the production efficiency.

[0036] Referring to Figure 3In order to improve the waterproof and dustproof level of the electric control box, a gasket for improving the sealing between the cover plate 6 and the box body 1 can be arranged at the edge of the inner side of the cover plate 6, which can be made of soft material such as sponge. See Figure 6 and Figure 11 Since the side where the operating handle 41 is located needs to meet the specified direction when the circuit breaker 4 is installed, in order to improve the assembly efficiency, the limiting frame 5 can be designed with a foolproof design. For example, the frame opening part of the frame body 51 is designed to be offset with the mounting hole on the supporting leg 52, that is, Figure 11 the frame opening part of the frame body 51 in Figure 11 is not located at the middle position of the upper first long hole 521 and the lower first long hole 521 in Figure 11 , but is arranged closer to the lower first long hole 521, or by Figure 11 It can be seen that the upper frame edge of the frame body 51 is wider than the lower frame edge, and the position of the frame opening part of the frame body 51 is more biased downward. That is, in the frame body 51 of the limiting frame 5, the frame widths of the opposite sides are inconsistent, thereby forming a foolproof design. Through the above-mentioned foolproof design, it can be prevented that the circuit breaker 4 is installed in reverse position, which causes the side where the operating handle 41 is located to face the opposite side.

[0037] Each embodiment in the specification is described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same and similar parts between each embodiment can be referred to each other.

[0038] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. The present application will not be limited to these embodiments shown in the text, but will be consistent with the widest range of principles and novel features disclosed in the text.
