[0052] The present invention discloses an electric control box with a rotary connection, which can realize the buckling of the base and the upper cover with one hand, has a short installation time, is not easy to lose parts, and is convenient to install

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0054] Refer to Figures 2 to 15 , the electric control box with a rotary connection of the present invention includes a base 1 and an upper cover 2. The base 1 is a shell with an open top and a closed bottom, and the upper cover 2 is a shell with an open bottom and a closed top. An arc-shaped hook 203 is provided on the upper cover 2, and a connecting shaft 103 is provided on the base 1. After the hook 203 is engaged with the connecting shaft 103, they are rotatably connected

[0055] Among them, the materials of the base 1 and the upper cover 2 are the materials commonly used for control boxes in the prior art, and no limitation is made here

[0056] The electric control box with a rotary connection of the present invention includes a base 1 and an upper cover 2 that are rotatably connected after being engaged. Through this connection structure, not only can the base 1 and the upper cover 2 be prevented from easily coming off, but also it is convenient to open and close the upper cover 2. The structure is simple and convenient for disassembly and assembly. For the electric control box with a rotary connection of the present invention, since the base 1 and the upper cover 2 are connected by the connection structure of the hook 203 and the connecting shaft 103, when the upper cover 2 is buckled on the base 1, the operator does not need to hold the upper cover 2 with both hands to align its end face with the entire end face of the base 1. It only needs to engage the hook 203 with the connecting shaft 103. The operator can use one hand to realize the buckling of the base 1 and the upper cover 2, with a short installation time, not easy to lose parts, and convenient to install

[0057] Among them, the upper cover 2 includes a top plate and a first side plate 201. The hook 203 is provided at a position of the first side plate 201 of the upper cover 2 close to the opening, such as Figure 11 andFigure 13 As shown in the figure. The base 1 includes a bottom plate and a second side plate 102, and a connecting shaft 103 is arranged at a position of the second side plate 102 of the base 1 close to the opening. The hook 203 is arranged corresponding to the connecting shaft 103, that is, the surface of the hook 203 in contact with the connecting shaft 103 is an arc-shaped inner side surface, and the radian of the arc-shaped inner side surface corresponds to the radian of the shaft surface of the connecting shaft 103. At the same time, the axial length of the hook 203 along the connecting shaft 103 is set with reference to the length of the connecting shaft 103, so as to ensure the reliability of the rotational connection between the base 1 and the upper cover 2 and avoid shaking during the buckling process of the base 1 and the upper cover 2.

[0058] In order to facilitate the connection of the hook 203 to the connecting shaft 103, the connecting shaft 103 is fixedly connected to the side plate of the base 1 through a connecting ear plate 107, that is, on the second side plate 102, so that a set distance can be provided between the connecting shaft 103 and the second side plate 102, thereby reserving a position for the connection of the hook 203. In order to facilitate the engagement with the hook 203, a limiting block 105 is arranged on one side of the connecting shaft 103 close to the second side plate 102 of the base 1, and a limiting groove 2031 is arranged on the hook 203. The limiting block 105 is engaged in the limiting groove 2031 to prevent the upper cover 2 from disengaging from the base 1. The limiting groove 2031 is arranged at the end of the hook 203 away from the upper cover 2, and the limiting groove 2031 is arranged on the surface close to the connecting shaft 103, such as Figure 13 and Figure 14 shown in the figure.

[0059] In order to facilitate the rotation of the hook 203 on the connecting shaft 103, a relief guiding groove 2032 is arranged on the hook 203. The relief guiding groove 2032 is arranged on the arc-shaped surface of the hook 203 close to the connecting shaft 103. The relief guiding groove 2032 is arranged around the connecting shaft 103, and the relief guiding groove 2032 is communicated with the limiting groove 2031, such as Figures 12 to 14 shown in the figure. The side surface of the relief guiding groove 2032 is used to limit both sides of the limiting block 105, so that the limiting block 105 can slide in the relief guiding groove 2032, enabling the upper cover 2 to rotate around the base 1. It can be understood that the width of the relief guiding groove 2032 is the same as the width of the limiting block 105, and the distance between the bottom surface of the relief guiding groove 2032 and the axis of the connecting shaft 103 is greater than the distance between the vertex of the limiting block 105 and the axis of the connecting shaft 103, so as to prevent the limiting block 105 from affecting the rotation of the hook 203 around the connecting shaft 103. Such as Figure 12 and Figure 14 shown in the figure. In order to communicate the relief guiding groove 2032 with the limiting groove 2031, a communication groove 2033 is also arranged on the hook 203.

[0060] In order to facilitate the connection of the hook 203 to the connecting shaft 103 and at the same time prevent the hook 203 from easily disengaging from the connecting shaft 103, the limiting block 105 includes an inclined surface 1051 and a first limiting surface 1052, such asFigure 8 and Figure 9 As shown in Figure 9 , a second limiting surface is provided in the limiting groove 2031, and the second limiting surface is in contact with the first limiting surface 1052. As Figure 14 shown in Figure 14 , the second limiting surface is the bottom surface of the limiting groove 2031. The limiting groove 2031 is a groove extending from the outer side surface of the hook 203 away from the connecting shaft 103 towards the inner side surface close to the connecting shaft 103. Among them, in order to facilitate the guiding when the hook 203 for connection is inserted, the inclined surface 1051 is arranged on the side where the hook 203 is inserted. One side of the inclined surface 1051 away from the first limiting surface 1052 is connected to the surface of the connecting shaft 103, and the side close to the first limiting surface 1052 is connected to one end of the first limiting surface 1052 away from the connecting shaft 103, so as to facilitate the hooking of the hook 203 on the connecting shaft 103.

[0061] In an embodiment, both the first limiting surface 1052 and the second limiting surface are horizontally arranged. Here, the horizontal arrangement means parallel to the bottom surface of the base 1. The inclined surface 1051 and the first limiting surface 1052 are connected through a connecting plane 1053, and the connecting plane 1053 is perpendicular to the first limiting surface 1052, so as to avoid the sharp corner at the connection position between the inclined surface 1051 and the first limiting surface 1052 and extend the service life of the limiting block 105.

[0062] In order to facilitate the locking and positioning of the buckled base 1 and the upper cover 2, a first connecting portion is provided on the base 1, and the first connecting portion is arranged close to the upper cover 2. A second connecting portion is provided on the upper cover 2, and the second connecting portion is arranged close to the base 1. Among them, the first connecting portion and the second connecting portion are correspondingly arranged. When the base 1 and the upper cover 2 are buckled, the first connecting portion and the second connecting portion are connected through a connecting device. Specifically, the first connecting portion is arranged on the outer surface of the second side plate 102 close to the opening position of the base 1, and the second connecting portion is arranged on the outer surface of the first side plate 201 close to the opening position of the upper cover 2. Such a structural arrangement makes the first connecting portion and the second connecting portion in contact when the base 1 and the upper cover 2 are buckled, so as to facilitate the connecting device to connect the base 1 and the upper cover 2 and realize the locking of the electric control box.

[0063] In an embodiment, the first connecting portion is a first connecting block 104, and the second connecting portion is a second connecting block 202. A first through hole 109 is provided on the first connecting block 104, and a second through hole 205 is provided on the second connecting block 202. The first through hole 109 and the second through hole 205 are correspondingly coaxially arranged. The base 1 and the upper cover 2 are connected through a connecting device passing through the first through hole 109 and the second through hole 205, and the connecting device is a lock or a connecting piece. Specifically, the connecting device is a self-tapping screw 3, as Figures 17 to 21As shown, the second through hole 205 is a stepped hole, including a necked-down hole 2052 and an enlarged hole 2051 that are connected. The aperture of the enlarged hole 2051 is larger than that of the necked-down hole 2052. The aperture of the necked-down hole 2052 is smaller than the major diameter of the thread of the self-tapping screw 3, and the aperture of the enlarged hole 2051 is larger than the major diameter of the thread of the self-tapping screw 3. When the self-tapping screw 3 passes through the necked-down hole 2052, self-tapping is achieved. By providing the enlarged hole 2051, when the self-tapping screw 3 exits the first through hole 109, a receiving space is reserved for the threaded section of the self-tapping screw 3, preventing the self-tapping screw 3 from being threadedly connected to the upper cover 2. It can be understood that the length of the enlarged hole 2051 is greater than the length of the threaded section of the self-tapping screw 3. At the same time, since the necked-down hole 2052 is smaller than the major diameter of the thread of the self-tapping screw 3, when the self-tapping screw 3 is loosened, the self-tapping screw 3 is prevented from disengaging from the upper cover 2. The first through hole 109 is a clearance hole, and the aperture of the first through hole 109 is slightly smaller than the major diameter of the thread of the self-tapping screw 3, facilitating the self-tapping connection of the self-tapping screw 3 within the first through hole 109. In another embodiment, the connecting device may also be a machine screw.

[0064] To improve the sealing performance of the electric control box, a ring groove 106 is provided on the end face of the base 1 in contact with the upper cover 2, and the ring groove 106 is arranged around the inner cavity 101 of the base 1. Correspondingly, a ring platform 204 is provided on the end face of the upper cover 2 in contact with the base 1. The ring platform 204 is arranged corresponding to the ring groove 106, and the thickness of the cross-section of the ring platform 204 is not greater than the groove width of the ring groove 106, so that when the upper cover 2 is buckled with the base 1, the ring platform 204 can be inserted into the ring groove 106.

[0065] To facilitate the insertion of the ring platform 204 into the ring groove 106, the cross-section of the ring platform 204 is conical. As Figure 16 shown, the width of one end of the cross-section of the ring platform 204 close to the end face of the upper cover 2 is W2, and the width of the other end away from the end face of the upper cover 2 is W1. W2 is greater than W1, and the width of one end of the cross-section of the ring platform 204 close to the end face of the upper cover 2 is the same as the groove width of the ring groove 106, so that when the upper cover 2 is buckled on the base 1, it is convenient for the ring platform 204 to be inserted into the ring groove 106. To improve the dust-proof performance, a sealing gasket 108 is placed in the ring groove 106. As Figure 17 shown, the sealing gasket 108 is a foam layer or a soft rubber material layer. When the upper cover 2 is buckled on the base 1, the top end of the ring platform 204 presses against the sealing gasket 108 to achieve dust-proof sealing. To facilitate placement, an installation base 4 is snap-connected to the outer bottom surface of the base 1 away from the upper cover.

[0066] For the rotationally connected electronic control box of the present invention, after the upper cover 2 and the base 1 are buckled, the rotation and positioning functions are realized through the arc surface of the hook 203. The clamping connection between the upper cover 2 and the base 1 is achieved by the elastic deformation of the hook 203 with a C-shaped opening provided on the upper cover 2, so that the upper cover 2 is clamped on the limiting block 105 protruding on the connecting shaft 103, thereby preventing the upper cover 2 and the base 1 from separating and facilitating installation and production. When the upper cover 2 and the base 1 are disassembled, the end of the hook 203 close to the limiting block 105 is pried, causing the hook 203 to elastically deform, and then the upper cover 2 and the base 1 can be disengaged. The rotationally connected electronic control box of the present invention is convenient for operation of disassembly and assembly, has a firm connection, and a simple structure that is easy to manufacture.
