for example, for other mechanical connections, the columns and connecting columns to be connected may be angled: when the steel sheet of the connecting piece is welded with the connecting column, the angle is determined, after the connecting pipe fitting is assembled in a meshing mode, the upper stand column and the lower stand column are sleeved outside the connecting pipe fitting, and the angle connection of the stand columns and the connecting column is achieved.
For another example, generally, for convenience, the cross section of the steel bed column of the present invention is square or rectangular, and thus the concealed connecting device includes four connecting pieces (two of the connecting columns on two edges of the welding bed hall), but in fact, the concealed connecting device of the present invention is still suitable for different objects, such as a cylindrical column, a column with a hexagonal cross section, or a column with an octagonal cross section: the connecting pieces can be meshed/meshed to realize the concealed connection mode of the upright post of one N-surface body and a plurality of (1-N) connecting posts. For the column with polygonal interface, the preferred built-in connection device comprises connecting pieces equal to the sides of the polygon, for example, the column with hexagonal section is preferably fixed into the connecting tube body with hexagonal section by adopting 6 connecting pieces, but 4-5 (even 3) connecting pieces can also be used for jointing into the connecting tube body with the polygon which is tightly abutted with the inner wall of the column only by the engaging sides and is in a relatively fixed position; at this time, the cross-sectional openings on the columns may be across different faces thereof, depending on the connection requirements, and depending on the transverse connection columns.
For example, the connecting member and the connecting column may be welded by means of nut anchoring or the like (in this case, the connecting portion of the connecting column is bent outward to form a plane for engagement with the steel sheet of the connecting member).
The utility model discloses an interior concealed connecting device is applicable to the built-in connecting device that various steel bed stands or steel bed room need connect. The appearance of the built-in connecting device cannot be seen, the attractiveness of the built-in connecting device is achieved, and in addition, the connecting device is firmer and more stable due to the mutual meshing mode of the combination of the connecting pieces. Meanwhile, the design that the safety buckle is arranged in the built-in mode and is matched with the built-in safety buckle can prevent loosening and random dismantling, the safety buckle needs to be destroyed when the safety buckle needs to be dismantled, the safety buckle is convenient for students to use aiming at the use group mainly suitable for accommodation of schools, the students are prevented from dismantling intentionally or unintentionally, and the effect of improving safety is achieved.
