Technical Field

The utility model relates to a connecting device, in particular to a built-in connecting device for vertically connecting a steel bed stand column with a bed hall and a steel bed comprising the connecting device.

Background

In China, main users of steel beds, particularly steel beds on the upper layer and the lower layer, are young students in schools and young people who just step into the society, the space utilization rate is high, and the method is suitable for the living requirement of high density; such users are characterized by being curious, and relatively involved. Therefore, strong, difficult to disassemble and break dormitory facilities are a major need for steel beds. The existing steel bed generally adopts a bolt or interface direct welding mode to carry out vertical connection of a stand column and a bed hall, but the modes have many hidden dangers: or is difficult to disassemble and not beneficial to transportation, or the joint is easy to loosen, has poor stability and is easy to be disassembled and damaged by young people with strong curiosity. Therefore, a stable, beautiful and easy-to-transport steel bed has been a long-sought direction in this field.

SUMMERY OF THE UTILITY MODEL

To the not enough and demand direction in this field, for realizing above-mentioned purpose, the utility model provides a following technical scheme:

a built-in connecting device for a steel bed for vertically connecting a column of the steel bed with a bed hall, wherein the device mainly comprises a connecting piece which can be connected with the bed hall, and the connecting piece is detachably jointed to a connecting pipe fitting tightly abutted against the inner wall of the column.

Preferably, the connecting piece is a rectangular steel sheet, and a connecting hole is formed in the center of the connecting piece, and the connecting hole is the same as the connecting column of the bed hall in size and shape in cross section and is used for being fixedly connected with the connecting column of the bed hall. Preferably, the connecting piece and the connecting column are connected at the position of the connecting hole in a welding mode.

Preferably, the rectangular coupling members have engaging pieces bent toward one side at both long sides thereof for detachably engaging the adjacent coupling members. The engagement members are preferably on the opposite side of the plane of the rectangular connecting element from the connecting column of the bed room, but may also be on the same side (the engagement points of the formed connecting tube members tightly abut against the inner wall of the upright). Preferably, the engaging member on each side has at least one protrusion and/or at least one protrusion slot, and the protrusions and the protrusion slots on the engaging members connected with each other on the adjacent connecting members are the same in number and at the same height and can be engaged with each other to fix the adjacent two connecting members.

To the above-mentioned device of the utility model, steel bed's stand includes two parts of last stand and lower stand, goes up the stand and has the opening respectively with the looks remote site of stand down on the face of the spliced pole of connecting the bed room (two faces), and the open-ended shape of last stand, size are the same with the first half in spliced pole cross-section, and the open-ended shape of stand, size are the same with the latter half in spliced pole cross-section down.

Furthermore, fixing holes are respectively formed in the length direction of the connecting piece and on two sides of the connecting hole, and after the connecting pipe fitting is tightly abutted against the inner walls of the upper stand column and the lower stand column, through holes are respectively formed in the positions, corresponding to the fixing holes, of the upper stand column and the lower stand column. The fixing holes and the through holes are aligned when the installation is completed, wherein the fixing holes and the through holes are fastened through by fasteners so as to realize the fixed connection of the upright posts and the connecting pipe fittings.

The fastener may be a nut (the fixing hole and the through hole need to have mating threads). Preferably, to prevent removal and back-out, the fastener may be a disposable safety clasp provided with a back-clasp (e.g., as shown in fig. 5). The arrangement is such that the safety catch is especially arranged for the case of school administration, and the safety catch is removed only by breaking it, so that the arrangement prevents loosening and any dismantling.

Optionally, the connecting device further comprises a fluorescent part, and the fluorescent part is sleeved or buckled at the connecting position between the upper upright post and the lower upright post, is used for shielding a gap at the connecting position, and can provide certain brightness for climbing the upper berth at night.

And simultaneously, the utility model also provides a steel bed, this steel bed's stand and bed room use the aforesaid interior concealed connecting device carry out perpendicular connection.

To the utility model discloses an interior concealed connecting device can have different variants to different service object:

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.
