[0041] like Figure 1-4 As shown, the present invention provides a foldable hanging lug structure for a distribution box, comprising:

[0042] The fixing accessory 1 includes a fixing accessory body 11 and a protrusion 12 disposed on the fixing accessory body 11;

[0043] Rotating shaft 2 is connected to one end of the fixed accessory body 11;

[0044] The movable accessory 3 includes a movable accessory body 31 connected to the rotating shaft 2 and a protrusion hole 32 provided on the movable accessory body 31. The protrusion hole 32 matches the shape of the protrusion 12. In the closed state, the movable accessory 3 and the fixed accessory 1 are engaged together by the interference fit between the protrusion 12 and the protrusion hole 32.

[0045] In use, the operator first connects the movable accessory 3 and the fixed accessory 1 through the rotating shaft 2, then fixes the whole assembly onto the distribution box through the fixed accessory 1; finally, the distribution box is assembled and installed.

[0046] The foldable hanging ear structure of this utility model's distribution box uses a rotating shaft 2 to connect the movable accessory 3 and the fixed accessory 1. The fixed accessory 1 can be fixed to the distribution box with screws or the like. During installation, the movable accessory 3 is unfolded and protrudes from the box body. In the closed state, the movable accessory 3 and the fixed accessory 1 are locked together by the interference fit between the protrusion 12 and the protrusion hole 32. Through the innovative folding design, the convenience of packaging, transportation and subsequent installation is effectively improved, and loss is avoided.

[0047] The convex hull 12 includes:

[0048] Horizontal plate 121;

[0049] The first side plate 122 has one end connected to the horizontal plate 121 and the other end connected to the fixing accessory body 11.

[0050] The second side plate 123 is connected to the horizontal plate 121 at one end and to the fixing accessory body 11 at the other end.

[0051] The horizontal plate 121, the first side plate 122, the second side plate 123, and the main body of the fixing accessory 11 enclose each other to form a through hole 124 inside the convex bulge.

[0052] The foldable hanging ear structure of this utility model's distribution box has a convex bulge 12 formed by a horizontal plate 121, a first side plate 122, a second side plate 123, and a fixing accessory body 11, which can save raw materials and reduce weight. In addition, devices such as locking posts can be set in the through hole 124 of the convex bulge to further enhance the locking effect in the closed state. Of course, it can also be connected to other objects in the open state. At the same time, it can also be equipped with tags, etc.

[0053] Preferably, transition surfaces 125 are provided at the connection points of the first side plate 122 and the horizontal plate 121, and at the connection points of the second side plate 123 and the horizontal plate 121. By providing transition surfaces 125, the convex bulge 12 can be more easily inserted into the convex bulge hole 32, improving the smoothness and convenience of operation.

[0054] Among them, the fixing accessory 1 also includes:

[0055] The first connecting plate 13 includes a first connecting upper protrusion 131, one end of which is connected to the fixing accessory body 11, and the other end of which is connected to the first connecting horizontal plate 132.

[0056] The first limiting plate 14 includes a first limiting upper protrusion plate 141. One end of the first limiting upper protrusion plate 141 is connected to the fixing accessory body 1, and the other end of the first limiting upper protrusion plate 141 is connected to the first limiting horizontal plate 142. The other end of the first limiting horizontal plate 142 is provided with a limiting abutment inclined surface 143.

[0057] Activity accessory 3 also includes:

The second limiting upper protrusion 341 is provided with an avoidance abutment groove 342 that matches the first limiting horizontal plate 142. In the open state, the movable accessory 3 and the fixed accessory 1 are abutted and limited by the groove wall of the avoidance abutment groove 342 and the limiting abutment inclined surface 142.

[0060] The foldable hanging ear structure of this utility model's distribution box has a first connecting upper convex plate 131 and a first connecting horizontal plate 132 forming a first step, and a second connecting upper convex plate 331 and a second connecting horizontal plate 332 forming a second step. In the closed state, the first and second steps are stacked. The rising part of the second step, namely the second connecting upper convex plate 331 and the movable accessory body 31, forms an upper convex space. In the open state, the second limiting upper convex plate 341 rotates into the upper convex space, thereby ensuring the realization of the limiting function through its own structure. It can adapt to various installation scenarios and spaces, improving applicability. Specifically, during installation, the movable accessory 3 is unfolded and protrudes from the box body. At this time, the movable accessory 3 and the fixed accessory 1 are locked together by the avoidance groove wall of the abutment groove 342 and the limiting abutment slope 142. Before this, in the closed state, the movable accessory 3 and the fixed accessory 1 are locked together by the interference fit between the convex bulge 12 and the convex bulge hole 32.

[0064] The rotating cylinder 23 has another part of the rotating shaft 22 inside it, and the rotating cylinder 23 is connected to the main body 31 of the movable accessory.

[0065] Preferably, the structure of the rotating shaft 2 is the same as that of the hinge, and will not be described again here. There are two first connecting plates 13 and two fixed cylinders 21, with the fixed cylinders 21 arranged on both sides of the rotating cylinder 23. When there are two first connecting plates 13 and two fixed cylinders 21, there is symmetry, the force is evenly distributed, and the problem of easy deformation caused by uneven force distribution is avoided.

[0066] Among them, the fixing accessory 1 also includes:

[0067] The first connecting hole 15 is provided on the main body 11 of the fixing accessory.

[0068] The present invention features a foldable hanging ear structure for the distribution box. The fixing accessory 1 can be fixed to the distribution box using screws or the like, with the screws matching the first connecting hole 15.

[0069] Preferably, there are two first connecting holes 15, which not only makes the installation more secure, but also makes the force more even.

[0070] Among them, activity accessory 3 also includes:

[0071] The second connecting hole 35 is provided on the main body 31 of the movable accessory.

[0072] The distribution box of this utility model has a foldable hanging ear structure, and the second connecting hole 35 can be used with screws and other connecting devices for fixed installation.

[0073] Among them, activity accessory 3 also includes:

[0074] The gourd-shaped hole 36 is located on the main body 31 of the movable accessory.

[0075] The foldable hanging ear structure of this utility model's distribution box serves as a connection when it needs to be connected to other objects, and can also save raw materials when it is not connected to other objects.

[0076] In general, the foldable hanging lug structure of the distribution box of this utility model has the following advantages:

[0077] 1. Significantly improves packaging efficiency: The foldable hanging ear structure of this utility model can be directly fixed to the distribution box for packaging, eliminating the need for separate packaging and saving packaging time;

[0078] 2. Significantly reduces the risk of loss: Because existing wall-mounted accessories are relatively small and easily lost when individually packaged, the foldable hanging ear structure of this utility model's distribution box is installed on the distribution box, so there is no risk of loss;

[0079] 3. Improved installation convenience: When installing the distribution box, the installer does not need to take out the foldable hanging ear structure of this utility model separately and install it on the distribution box before the distribution box can be installed. Instead, the distribution box can be taken out directly for installation.

[0080] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
