Example Embodiment

[0023] Example 1, see image 3 The retractable fixing structure between the telescopic sleeve 2 and the box body 1 is as follows: the telescopic direction of the telescopic sleeve 2 is set as the axial direction of the bottom box, and the inner sides of the two opposite sides of the box body 1 are respectively provided with A number of transverse grooves 7 perpendicular to the axial direction of the bottom box, the outer sides of the two opposite sides of the telescopic sleeve 2 are respectively provided with a number of transverse convex strips 8 perpendicular to the axial direction of the bottom box. The shape and size of the lateral grooves 7 are matched, and the number of the lateral protruding strips 8 is less than the number of the lateral grooves 7 , and the lateral protruding strips 8 fall into the lateral grooves 7 . In this way, as long as a certain amount of force is used to push the telescopic sleeve 2 toward the box body 1, the transverse protruding strips 8 of th...

Example Embodiment

[0024] Example 2, see Figure 4 , the retractable fixing structure between the telescopic sleeve 2 and the box body 1 is as follows: it also includes a positioning bolt 9, a positioning block 10 is provided on the inner side of the side surface of the telescopic sleeve 2, and the inner side of the side surface of the box body 1 , There is a support block 11 near the bottom surface of the box body 1. Generally speaking, the telescopic sleeve 2 and the bottom surface of the box body 1 have a certain distance, so the inner side of the side between the telescopic sleeve 2 and the bottom surface of the box body 1 can be set Positioning block 10. The positioning bolt 9 is rotatably fixed to one of the positioning block 10 or the supporting block 11 , and is threadedly connected to the other of the positioning block 10 or the supporting block 11 . In this way, the distance between the positioning block 11 on the inner side of the telescopic sleeve 2 and the support block 12 on the i...

Abstract

The invention discloses a bottom box of a switch or a socket. The bottom box of the switch or the socket comprises a box body and a stretching sleeve, wherein an opening is formed in one side of the box body, the box body is provided with a bottom surface and four lateral sides, wiring holes are formed in the lateral sides of the box body, the stretching sleeve is provided with four lateral sides and is fixed in the box body, the four lateral sides of the stretching sleeve are close to the inner sides of the four lateral sides of the box body respectively, wiring ports are formed in positions, corresponding to the wiring holes in the lateral sides of the box body, of the lateral sides of the stretching sleeve, a stretchable fixing structure is arranged between the stretching sleeve and the box body, connecting blocks are arranged on the inner sides of two opposite lateral sides of the stretching sleeve, and connecting screw holes are formed in the connecting blocks. According to the bottom box of the switch or the socket, due to the fact that the stretching sleeve is arranged and the stretchable fixing structure is arranged between the stretching sleeve and the box body, the height of the box body can be adjusted freely to meet requirements of variable heights of indoor decoration wall covering materials, the switch or a socket panel can be fixed firmly, the surface layer is attractive, and requirements of fire protection rules are met.

Description

technical field [0001] The invention relates to an electrical installation device, more specifically a bottom box installed in a wall, under a switch or socket panel, and belongs to the field of building electrical technology. Background technique [0002] The bottom box of the switch or socket includes a box body with an opening on one side, a threading hole on the side of the box body, connecting blocks are provided on both sides of the opening of the box body, and connecting screw holes are provided on the connecting block. When decorating the interior, generally the bottom box of the switch or socket is pre-embedded in the interior wall. After the decoration is basically completed, when installing lamps and appliances, install the switch or socket board at the bottom box of the switch or socket . In some relatively complex interior decoration, especially in the decoration of high-end decoration interior walls such as high-star hotels and high-end residences, materials o...
