[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0024] Please see Figure 1-8 The present invention provides an embodiment of a concealed bottom box, comprising a bottom box 1, wherein the inner side of the bottom box 1 is provided with a slot 2, and the slot 2 is connected to a hanging ear 4 and a protective member 3, and the protective member 3 is installed on the outside of the hanging ear 4 to prevent impurities from adhering to the hanging ear 4; the hanging ear 4 and the protective member 3 are fixed in the slot 2 by the cooperation of the slot 4 and the slot 2.

[0025] After both the hanging ear 4 and the protective element 3 are installed in the slot 2, the protective element 3 is used to protect the hanging ear 4 from the outside, thus solving the problem of existing hanging ear type boxes where the hanging ear is directly exposed, causing sand and cement to easily adhere to the hanging ear or block the internal thread hole on the hanging ear. In particular, both the protective element 3 and the hanging ear 4 can be inserted into the slot 2 perpendicular to the wall, and after the protective element 3 is installed, it can also press the hanging ear 4 tightly into the slot 2 from the outside. Therefore, while facilitating the assembly of the protective element 3 and the hanging ear 4, it can also improve the stability of the hanging ear 4 in the slot 2.

[0026] Furthermore, since the hanging ear 4 is provided with a locking foot 6, after the locking foot 6 is inserted into the slot 2, the upper end face of the locking foot 6 is connected to the stepped surface 9 provided on the inner wall of the slot 2; therefore, the hanging ear 4 can be initially fixed by using the connection between the locking foot 6 and the stepped surface 9; wherein, the locking foot 6 and the hanging ear 4 are an integral structure, and the locking foot 6 is formed by using a punching process.

[0027] Furthermore, after the insert plate 30 of the protective component 3 is inserted into the slot 2, the limiting protrusion 31 on the insert plate 30 connects with the lower end face of the hanging ear 4. Therefore, by using the locking foot 6 to abut against the stepped surface 9 and the limiting protrusion 31 to abut against the lower end face of the hanging ear 4, it is difficult to pull out the hanging ear 4 and the protective component 3 after they are connected to the slot 2, thus ensuring the stability of the hanging ear 4 in the slot 2.

[0028] In addition, since the insert plate 30 covers the mounting portion 5 of the lug 4 with the cover plate 33, the protective component 3 can be inserted into the slot 2 through the insert plate 30, and the mounting portion 5 is covered by the cover plate 33. Based on this, while the protective component 3 can be installed smoothly, the cover plate 33 can also cover a large area of ​​the mounting portion 5 to improve the protective capability of the protective component 3.

[0029] To facilitate the rapid separation of the cover plate 33 and the insert plate 30, and to fully expose the mounting portion 5 on the lug 4, a beveled groove 32 is provided at the connection between the cover plate 33 and the insert plate 30. This beveled groove 32 enables the cover plate 33 and the insert plate 30 to be movably connected. Therefore, the beveled groove 32 reduces the connection strength between the cover plate 33 and the insert plate 30, allowing the cover plate 33 to separate from the insert plate 30 at the beveled groove 32.

[0030] Based on the above plan, specifically as follows: Figure 6 As shown, since the width of the protective member 3 is equal to the width of the slot 2, and the width of the hanging ear 4 is less than the width of the protective member 3, the hanging ear 4 can swing in the width direction of the slot 2 after it is installed in the slot 2. At the same time, the bottom box 1 is also provided with a slot 7, and the slot 7 is an oblong slot, so that bolts and other fasteners can be smoothly inserted into the slot 7 after passing through the mounting part 5.

[0031] In summary, by utilizing the swing of the hanging ear 4 and the setting of the slot 7, fasteners such as bolts can be smoothly connected to the slot 7, so as to fix the switch panel on the base box 1.

[0032] Furthermore, since the upper edge of the slot 2 is provided with a groove 8, and the upper end of the insert plate 30 is adapted to and connected to the groove 8 through the provided horizontal plate 34, when the bottom surface of the horizontal plate 34 contacts the bottom surface of the groove 8, it can prevent the protective member 3 from continuing to move into the bottom box 1, so that the protective member 3 can be installed smoothly in place; wherein, after the horizontal plate 34 is inserted into the groove 8, the upper end surface of the horizontal plate 34 is not higher than the opening surface of the bottom box 1.

[0033] In addition, since the slot 2 completely penetrates the bottom box 1, it not only facilitates the processing of the stepped surface 9, but also facilitates the demolding of the bottom box 1.

[0034] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
