Description

Combined keel three-dimensional adjustable bottom box opening-free connection structure Technical Field The utility model belongs to the field of indoor decoration engineering, and particularly relates to an opening-free connecting structure of a three-dimensional adjustable bottom box of a combined keel. Background The switch bottom box is an important component installed on the wall keel, and the installation bottom box can protect a switch circuit from being corroded by moisture, dust or other pollutants on the wall surface, prolong the service life of the switch, facilitate installation, facilitate later maintenance and replacement, provide necessary support and fixation, and ensure the stability of the switch in the installation and use processes. The existing switch bottom box is generally arranged on a wall keel, if the installation position of the switch bottom box is proper to the installation position of the switch bottom box, the switch bottom box can be directly connected with the keel through an anchor, if the installation position of the switch bottom box is improper to the installation position of the switch bottom box, an auxiliary installation frame is required to be manufactured by using a batten and the like, the batten is firstly fixed on the keel, and then the bottom box is fixed on the batten to be indirectly connected with the keel. The problem that the installation position of the bottom box is limited obviously appears in the above fixed installation mode, and once the bottom box is connected with the fossil fragments, the adjustment of adaptability can not be carried out according to actual conditions. Meanwhile, the pipeline connected with the line box needs to pass through the upright keel, the common practice is to directly open a line hole on the upright keel, but the line hole still needs to judge the vertical installation position of the bottom box, so that the line is paved from the corresponding hole position, once the position of the bottom box needs to be adjusted, the paved pipeline also needs to be readjusted, and the adaptability is poor. The existing improvement mode is to design a keel type bottom box cross beam, screw connection or clamping connection is carried out on two ends of the bottom box cross beam and upright keels on two sides, and then a partition plate is directly arranged on the bottom box cross beam to form a bottom box. Although the vertical installation position of the bottom box can be adjusted by adjusting the connection position of the bottom box cross beam and the upright post keels, the horizontal left and right installation positions of the bottom box are still fixed and difficult to adjust due to the fact that the bottom box is directly formed by the bottom box cross beam, and meanwhile, the installation position of the bottom box cross beam in the horizontal front and rear direction is required to be adjusted by adjusting the position of the bottom box cross beam, so that the method is very complicated. Therefore, a bottom box connecting structure capable of being adaptively adjusted in the vertical, horizontal left and right directions and horizontal front and rear directions is urgently needed, the structural connection is free from being perforated, and meanwhile, pipelines on upright post keels can be adaptively laid without repeated paving when the bottom box is adjusted. Disclosure of utility model The utility model aims to provide a three-dimensional adjustable bottom box opening-free connecting structure of a combined keel, which aims to solve the problems that the bottom box and the keel connecting structure need to be connected in a punching way, the installation position of the bottom box cannot be adjusted in three dimensions, the wiring of an upright post keel needs to be reinstalled according to the adjustment position of the bottom box, and the adaptability is poor. In order to achieve the above purpose, the utility model adopts the following technical scheme: a three-dimensional adjustable bottom box opening-free connection structure of a combined keel comprises a keel column, a bottom box bearing keel beam and a bottom box which are oppositely arranged at two sides in parallel, The inner side surfaces of the keel posts are provided with keel external holes in rows at intervals along the length direction, the keel external holes of the keel posts on two sides have the same module and have opposite open holes, The bottom box bearing keel beam comprises a keel body and Liang Zhuka pieces, the cross section of the keel body is a first groove with a downward opening, the first groove comprises an integrally formed top web plate and a side plate, the top web plate is provided with an on-beam adjusting hole, liang Zhuka pieces are corner pieces, the first groove comprises an integrally formed horizontal beam connecting plate and a vertical column clamping plate, the horizontal beam connecting plate is inserted into the first groove
