Assembly structure for bed column and lateral bed rod

An assembly structure for a bed column and a lateral bed rod, wherein:

• the bed column is arranged vertically and comprises an upper column and a lower column that are configured to be inserted together in an up-and-down direction,
• an upper end of the lower column comprises a joint section formed by reducing a diameter of the upper end of the lower column,
• a positioning step is formed at a bottom end of the joint section,
• the positioning step is disposed no lower than an upper surface of the lateral bed rod,
• the upper column is sleeved on the joint section from top to bottom and is stopped at the positioning step,
• the lateral bed rod is horizontally, laterally arranged,
• an end surface of the lateral bed rod is connected with a locking piece,
• the locking piece is adjacent to a side of the positioning step and abuts an outer side of the upper column and an outer side of the lower column,
• a first portion of the locking piece that extends upward beyond the upper surface of the lateral bed rod is locked with an upper bolt,
• the upper bolt enables the locking piece, the upper column, and the joint section to be locked together,
• a second portion of the locking piece that extends downward beyond a lower surface of the lateral bed rod is locked with a lower bolt,
• the lower bolt enables the locking piece and the lower column to be locked together,
• the upper column is locked with a reinforcing bolt,
• the reinforcing bolt enables the upper column and the joint section to be locked together in absence of the lower column, and
• the reinforcing bolt is located above the upper bolt.
