[0002] The bottom box is a pre-buried box in the wall, used to connect or accommodate wires, provide a transition for various electrical circuits, and thus protect the circuits. Generally speaking, various wall switches or wall sockets in the room are connected to the circuits in the bottom box, and then fixed to the surface of the bottom box, thus ensuring the neatness and beauty of the wall.
[0003] The existing bottom box is an open structure, and a bottom box cover is arranged on its surface, which is used to fix the line in the cavity inside the bottom box and prevent impurities such as dust and cement slurry from entering. However, after the existing bottom box cover and the bottom box are installed, if the two are separated, the bottom box cover or the bottom box will be damaged, resulting in failure of the matching structure between the bottom box cover and the bottom box. Therefore, the bottom box cover is easy to separate from the bottom box and cannot be reused, which provides inconvenience for the adjustment and maintenance of the line.
[0004] In view of this, the present utility model is proposed. Utility Model Content
[0005] The utility model aims to provide a bottom box with a rotatable cover, which can realize lossless separation of the bottom box cover and the bottom box body, thus providing convenience for adjustment and maintenance of circuits.
[0006] The embodiment of the utility model is achieved as follows:

[0009] The side surface of the bottom box cover is provided with a positioning piece corresponding to each limiting groove, the positioning piece protrudes from the side surface of the bottom box cover, and the area of the bottom box cover close to the side surface is also provided with a deformation hole passing through the upper and lower surfaces, and each deformation hole is provided in a one-to-one correspondence with each positioning piece.
[0010] Optionally, the limiting groove includes an opening area and an arc area, the diameter of the arc area is larger than the diameter of the positioning piece, and the diameter of the opening area is smaller than the diameter of the positioning piece.
[0011] Optionally, the diameter of the arc-shaped area is 0.5 mm to 2 mm larger than the diameter of the positioning piece, and the diameter of the opening area is 0.5 mm to 2 mm smaller than the diameter of the positioning piece.
[0012] Optionally, the diameter of the arc-shaped area is 1 mm larger than the diameter of the positioning piece, and the diameter of the opening area is 1 mm smaller than the diameter of the positioning piece.
[0013] Optionally, one end of the positioning member away from the bottom box cover is a reducing portion, and the reducing portion increases in size in a direction approaching the bottom box cover.

[0029] Please refer to Figure 1 and Figure 2 The present embodiment provides a bottom box 100 with a rotatable cover, which includes a bottom box body 110 and a bottom box cover 120. The bottom box body 110 is a box-shaped structure with one end open, and the bottom box cover 120 is gap-matched with the open end of the bottom box body 110.
[0030] A limiting groove 111 is provided on the end face of the open end of the bottom box body 110. The limiting grooves 111 are designed in pairs. There are two limiting grooves 111 in each pair, and they are respectively located on two parallel surfaces on the end face of the open end of the bottom box body 110. The connecting lines of the two limiting grooves 111 in each pair are parallel to each other.
[0031] The number of the limiting grooves 111 can be set to four, six, eight, etc. as required. In the present embodiment, the number of the limiting grooves 111 is four, that is, two pairs.
[0032] In this embodiment, the bottom box body 110 is a cubic structure, and the connecting line of the two limiting grooves 111 in each pair is parallel to one side of the bottom box body 110 .
[0033] The side surface of the bottom box cover 120 is provided with a positioning piece 121 corresponding to each limiting groove 111, so the positioning pieces 121 are also provided in pairs. Each positioning piece 121 protrudes from the side surface of the bottom box cover 120 and can be selectively accommodated in the limiting groove 111. The area near the side surface of the bottom box cover 120 is also provided with a deformation hole 122 that passes through the upper and lower surfaces, and each deformation hole 122 is provided in a one-to-one correspondence with each positioning piece 121.
[0034] In this embodiment, the limiting groove 111 is a groove extending along the end surface of the bottom box toward the bottom of the bottom box. In order to ensure a stable fit between the positioning piece 121 and the limiting groove 111, the limiting groove 111 includes an opening area and an arc area. The opening area is located at the end surface of the bottom box, and the arc area is away from the end surface of the bottom box. The diameter of the arc area is larger than the diameter of the positioning piece 121, and the diameter of the opening area is smaller than the diameter of the positioning piece 121.
[0035] Preferably, in order to prevent the positioning member 121 from being separated from the limiting groove 111 , the diameter of the arc area is 1 mm larger than the diameter of the positioning member 121 , and the diameter of the opening area is 1 mm smaller than the diameter of the positioning member 121 .
[0036] Furthermore, in order to ensure that the positioning member 121 is smoothly inserted into the limiting groove 111 , the end of the positioning member 121 away from the bottom box cover 120 is a reducing portion, and the reducing portion increases gradually in the direction approaching the bottom box cover 120 .
[0037] Therefore, in the process of the positioning member 121 being inserted into the limiting groove 111, the cooperation of the reducing portion ensures that the positioning member 121 can smoothly pass through the opening area of the limiting groove 111, thereby being inserted into the arc area. Since the area of the positioning member 121 close to the side surface of the bottom box cover 120 is of normal diameter, which is slightly larger than the diameter of the opening area, the positioning member 121 is not easy to fall out of the limiting groove 111 after being inserted.
[0038] In addition, the positioning member 121 and the limiting groove 111 need to be smoothly inserted through the deformation hole 122, so that the positioning member 121 and the limiting groove 111 will not separate under the action of no external force after insertion.
[0039] In this embodiment, the thickness of the bottom box cover 120 is 10 mm to 12 mm.
[0040] In this embodiment, in order to ensure that the deformation hole 122 is deformed during the squeezing process of the positioning piece 121 and to ensure that the positioning piece 121 is smoothly inserted into the limiting groove 111, the distance between the deformation hole 122 and the side surface of the bottom box cover 120 where its corresponding positioning piece 121 is located is 3mm to 10mm.
[0041] In this embodiment, in order to ensure that the deformation hole 122 is deformed during the squeezing process of the positioning member 121, to ensure that the positioning member 121 is smoothly inserted into the limiting groove 111, and to ensure that the bottom box cover 120 is easy to flip over, the gap between the bottom box cover 120 and the bottom box body 110 is less than or equal to 8 mm.
[0042] The present invention provides a bottom box 100 with a rotatable cover, and its working principle is as follows:
[0043] First, install the positioning piece 121 on one of the side surfaces of the bottom box cover 120 in the corresponding limiting groove 111, and then close the bottom box cover 120, so that the positioning piece 121 at the other opposite end is inserted into the arc-shaped portion along the opening of the limiting groove 111. During the insertion process, the deformation hole 122 is squeezed and deformed, and the auxiliary positioning piece 121 is inserted into the limiting groove 111 to complete the installation.
[0044] When it is necessary to repair or adjust the circuit, push the bottom box cover 120 to the right to make the left positioning piece 121 disengage from the left limiting groove 111, and then push it in the opposite direction to take out the right positioning piece 121 from the right limiting groove 111. The process of taking out can be taken out in pairs or as a whole. When the positioning pieces 121 are taken out from the limiting groove 111 in pairs, and only one pair of positioning pieces 121 is installed in the limiting groove 111, the bottom box cover 120 can be rotated relative to the line connecting the pair of positioning pieces 121, so as to complete the repair and adjustment of the circuit without removing the bottom box cover 120.
[0045] The present invention provides a bottom box 100 with a rotatable cover, which has at least the following advantages:
[0046] During the installation process, the positioning piece 121 is accommodated in the limiting groove 111, thereby realizing the connection between the bottom box body 110 and the bottom box cover 120. Since the positioning piece 121 protrudes from the side surface of the bottom box cover 120, in order to facilitate the positioning piece 121 to be accommodated in the limiting groove 111, a deformation hole 122 that passes through the upper and lower surfaces of the bottom box cover 120 is also opened on the bottom box cover 120 corresponding to each positioning piece 121. Therefore, when the positioning piece 121 is inserted into the limiting groove 111, the positioning piece 121 will squeeze the deformation hole 122, causing the area of the deformation hole 122 to become smaller, so that the positioning piece 121 can be smoothly inserted into the limiting groove 111.
[0047] In addition, when only one pair of limiting grooves 111 accommodates the positioning piece 121, the bottom box cover 120 can be flipped with the line connecting the two limiting grooves 111 as the axis, which provides convenience for the adjustment and maintenance of the line without damaging the structure of the bottom box and the bottom box cover 120. After the maintenance and installation is completed, the remaining positioning piece 121 is snapped into the slot to achieve a fixed connection between the bottom box and the bottom box cover 120.
[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
