Description

Technical Field

[0001] The invention relates to the field of beds, and more particularly to a connection structure of a bed beam and a column and a bed body comprising the structure. Background Art

[0002] In the existing bed structure, the connection between the bed beam and the column is generally achieved by welding an iron sheet at the end of the bed beam, then attaching the iron sheet to the column and then screwing it through the iron sheet to the column to achieve the connection between the bed beam and the column. However, this method has the following disadvantages in actual application: 1. The iron sheet is protruding from the end of the bed beam, which occupies a certain space during transportation, causing inconvenience during transportation; 2. The iron sheet has a certain thickness, so there is a gap between the assembled bed beam and the column. The slight shaking of the bed frame during use may cause friction and generate noise, which is more obvious when the iron sheet is connected to the metal column; 3. The bed beam is screwed to the column through an iron sheet, but there is no direct contact between the bed beam and the column. The stress points are concentrated and the connection is not stable enough. It may become loose or the connection unstable due to excessive stress caused by external factors (such as shaking, impact, weight), causing safety hazards. Summary of the invention

[0019] The connector has a bottom surface 31 and four sides 32. The top surface of the connector is open, and the opening allows the bed beam 2 to be inserted. The outer side of the bottom surface 31 of the connector fits the shape of the column 1 and contacts the inner wall of the column 1 opposite to the plug hole 11, so that the bottom surface 31 of the connector is in close contact with the inner wall of the column 1. After the bed beam 2 is inserted into the connector, it fits the inner wall of the connector, that is, a slot for the bed beam to be inserted is formed in the middle of the connector, and the slot just corresponds to the shape of the end of the bed beam 2, so that the end of the bed beam can fit in the inner wall of the connector after being inserted into the connector to achieve a tight connection. Furthermore, a retaining edge 33 is protruded outwardly around the top surface of the connector, and the retaining edge 33 can be stopped outside the plug hole 11 and fit on the outer wall of the column, so that the retaining edge 33 fits and clamps on the outer walls around the outside of the plug hole 11, further positioning the connector. At the same time, a connecting piece 21 connected to the surrounding inner walls is provided on the inner side of the end of the bed beam 2, and corresponding screw holes are provided on the side wall of the column 1 at the bottom surface 31 of the connecting piece and on the connecting piece of the bed beam 2, and the bottom surface 31 of the connecting piece is also provided with a screw hole or a through groove for the screw to pass through. In this embodiment, a first screw hole 12 is provided on the column, a second screw hole 311 is provided on the bottom surface of the connecting piece, and a third screw hole 211 is provided on the connecting piece 21.
